Common pitfalls in luxury renovation and how to avoid them

2026-06-22T12:02:06Z

Floor:

Having worked on over 40,000 projects from compact urban extensions to the grandest of [https://idsystems.co.uk/blog/idsystems-named-grand-designs-premium-partner/ Grand Designs TV] new home projects, [https://idsystems.co.uk/ IDSystems] has seen it all. Below, Technical Sales Manager Edward Stobart has rounded up the most common luxury renovation issues he has encountered, and how to avoid them:

* Underestimating budgets and project scope is a main cause of failure, as well as cutting costs on important structural elements.
* A disconnected supply chain and unclear responsibilities also frequently cause issues.
* Failing to comply with planning & building regulations can stop a project in its tracks, and can be costly to fix.

== 1. Cutting costs on important structural elements ==

Any Grand Designs fan knows this issue well: ambitious projects going wildly over budget and schedule due to poor initial planning. Stobart warns there is another factor at play: attempting to cut costs in the wrong places. He states: “It is easy when budgets are tight to think about cutting costs, particularly when glazing is one of the most expensive elements of a build. But quality is definitely linked to price, and saving a few thousand pounds now but ending up with doors that cause problems constantly just isn't worth the risk.”

The key to maintaining your budget is to focus on the details from day one:

* Your budget should include a contingency fund of 15-20% which is more realistic for complex luxury builds than the 10-15% often quoted for standard projects.
* Work with trusted partners like quantity surveyors and experienced architects to establish realistic cost estimates.
* Insist on detailed quotes from all suppliers. When comparing providers, especially for critical elements like glazing, examine the specifications closely.
* Invest in high-quality work for foundational and structural elements like [https://idsystems.co.uk/windows/ windows], [https://idsystems.co.uk/doors/ doors], and [https://idsystems.co.uk/blog/the-future-homes-standard-2025-and-what-it-means-for-glazing/ insulation]. You can make cost savings later on non-structural elements and decorative items.

“We’ve had projects in the past where architects have insisted on a single huge window manufactured from a single glass unit that looks absolutely stunning but is incredibly costly to manufacture and install, whereas opting to split the same window into three frameless sections considerably reduces not only the cost of the materials but also the installation.” Edward Stobart says. “When a budget is involved, there will always be trade-offs to be made; it is about finding the ones that you can implement without impacting how you enjoy the house in the long run.“

== 2. Too many points of contact ==

Edward Stobart says, “In my experience, one of the most common sources of project delays is a disconnected supply chain. If you have a supplier buying from a fabricator and then subcontracting the fitting, there is so little control over responsibility and quality. One of the main reasons we manufacture, supply, and install ourselves is so we aren’t reliant on third parties to make or fit the products.”

To avoid a disconnected supply chain, consolidate contracts wherever possible, especially for critical components like glazing. Duncan Foster from [https://www.youtube.com/watch?v=9bvkaW6IGqs Duncan Foster Architects] says: “The general rule I always think with glazing is the more you can get wrapped up in one contract, the better. Because there's one point of contact for the client, one point of contact for me, and one point of contact for the contractor and his programming. So, it was really critical that all the different glazing systems we wanted in here could all be supplied and installed by one manufacturer.”

== 3. Not assigning responsibilities clearly ==

A successful project is built on a complex relationship between the homeowner, architect, builder, and various specialist suppliers. But when communications break down, a lack of clarity over responsibilities is often the cause. This can create unnecessary friction, with specialist contractors often bearing the brunt of issues that originated elsewhere.

“When it comes to architects and builders, the messages can get mixed as they are approaching the project with their own considerations in mind. Architects will often look at the overall vision and the aesthetics of a project primarily, whereas a builder is considering how it is going to be practical to build,” says Stobart.

“By providing detailed specifications, maintaining open lines of communication with every party involved, and insisting on clear sign-offs at critical stages, you can remove ambiguity from your project.”

To ensure clear communication in your project:

* Set out responsibilities and lines of oversight from the beginning of the project.
* Provide a clear and detailed project plan to all parties.
* Make sure to use experienced suppliers.

== 4. Failing to comply with planning and building regulations ==

The complexities of building regulations can be a minefield, but failure to comply can be a hugely frustrating and expensive mistake, and is often discovered right at the end of the project when you're ready to move in.

“Don’t ignore key features because they impact the aesthetic appeal of the finished system,” Stobart advises. “Finding out when you go to get sign-off on the house that the doors don't comply with the relevant [https://idsystems.co.uk/blog/building-regulations-part-f-sliding-bifold-doors-ventilation/ building regulations] because they don't have trickle vents or don't include security laminate glass can be hugely frustrating.”

“Suppliers know this, so making sure you get accurate and honest advice upfront is crucial. This issue is often linked to choosing low-cost suppliers who may not be as diligent about compliance. Ultimately, the responsibility rests with the homeowner, but you are reliant on the advice of experts - so use suppliers you can trust.”

== The right team for your dream project ==

Luxury renovation projects are complex, but they don't have to be stressful. By anticipating these common pitfalls from day one, you can navigate the process with confidence.

The keys to success are always the same:

* Meticulous planning
* Clear communication
* Strong partnerships with experienced, reputable experts.

The rise of ultra-slim sliding doors has created a new interior design challenge: how to incorporate window dressings on large moving panels? While homeowners invest heavily in floor-to-ceiling glass to maximise views, many are left facing issues with solar glare, "fishbowl" privacy concerns, and summer overheating.

Glazing experts at [https://idsystems.co.uk/ IDSystems] share how to navigate the technical complexities of fitting blinds on contemporary sliding systems.

* Because sliding doors overlap and move horizontally, traditional blinds are often unsuitable as they can obstruct the sliding mechanism or interlock.
* Accurate and detailed measurements are critical, as mistakes can result in clogged up sightlines or awkward finishes.

“For example, roman blinds can look great,” says Edward Stobart. “Just ensure you mount them high enough so the ‘stack’ doesn’t cover the top of the glass or sag so you hit your head when walking through.”

Stobart has rounded up his tips for fitting blinds on sliding doors, from mounting options to measurement:

== Deciding which blinds and where to mount them ==

=== Ceiling-mounted blinds ===

The most common fitting on sliding doors. By mounting on the ceiling above the frame, the doors can slide freely without hitting the blinds.

=== Recessed blinds ===

Sliding screens can also be recessed into the side reveal of the doors. Set internally to the tracks of the doors, [https://idsystems.co.uk/blinds/insect-screens-and-shades/ the retractable sun shades and insect screens] offer a stylish solution for inside-outside living. As these screens are incorporated into the door system itself, they are not generally suited for retrofitting to existing doors.

=== External blinds ===

An increasingly popular option, external blinds sit on the outside of the glass and prevent direct sunshine from reaching the door system. By preventing sunlight from reaching the glass, these blinds can significantly reduce overheating.

=== Integrated blinds ===

Lastly, while it’s not an option for sliding doors, there is another option for [https://idsystems.co.uk/slide-and-turn-doors/ slide and turn] and [https://idsystems.co.uk/bifold-doors/ bifold door] systems. This approach sees Venetian or pleated blinds installed between the glass of a double or triple-glazed unit, creating a maintenance-free way to create privacy or reduce glare.

== How to measure your sliding doors to fit blinds ==

Accurate measuring is essential to achieve a clean finish and proper functionality.

* Outside recess measurement: Measure the full width of the opening (horizontally), allowing for overlap on each side to ensure full coverage and minimise light gaps.
* Panel alignment: For wider sliding doors, multiple roller blinds are often the most practical solution. Measure each section individually, aligning with the panels for greater flexibility and easy access.
* Drop measurement: Measure the height of the opening (vertically), from the intended fixing point to the desired finish, usually just below the door frame or to the floor level.
* Measure obstructions: ensure to measure any obstructions, such as door handles or frames, to ensure the blind can hang freely without interference.
* Stacking depth: Measure the space that fully opened blinds will take up, which will vary depending on the style and size of the blinds.

“The most common mistake people make when measuring for blinds is forgetting the ‘stacking depth’. If you choose vertical blinds that drop down from the ceiling, remember that when the door is fully open, those blinds have to bunch up somewhere,” Stobart explains. “Ensure your track extends past the door opening so the blinds don’t block your view, or the breeze when the doors are open.”

Stobart gives an extra piece of advice: “If fitting within a recess, it’s important to measure in multiple places and use the smallest dimensions, while also confirming there is enough depth for the blind mechanism.”

== Choosing the right type of blinds for your sliding doors ==

* Roller blinds: Usually, they are installed above the door and roll up neatly to vanish out of sight, leaving your view completely unobstructed when open. The most efficient way of designing the blinds is to opt for one blind per panel – this gives you flexibility when opening the doors.
* Venetian blinds: Vertical Venetian blinds remain a hugely popular option for many people simply because they are incredibly practical. Individual slats hang vertically from a track and can be tilted to filter light or drawn back completely.
* Roman blinds: If roller or Venetian blinds look too ‘office-like’ or clinical, Roman blinds offer a softer, more furnished alternative. They bring the feel of curtains to your sliding patio doors without the floor-to-ceiling bulk.
* Sliding screens: Large, wide panels of fabric roll out from a cassette from the side along a track. Whether you opt for a blackout style sun screen or choose an insect screen (or both) the panels slide in a similar way to the door itself.

== Finding the right window dressing for your glazing ==

Choosing the right blinds for your sliding doors is likely the finishing touch to your renovation project. Whether you choose the clean lines of a panel blind or the practicality of Venetian blinds, make sure your choice complements your home’s style and the quality of your glazing.

Mastering flush tracks: A technical guide to achieving an effective weather seal

With UK searches for the term ‘indoor outdoor living’ increasing 51% year-on-year according to Google Trends, there is a growing demand for seamless transitions between indoor and outdoor living. [https://idsystems.co.uk/ IDSystems] Technical Sales Manager Edward Stobart supported countless projects, including those where previous mistakes have had to be corrected.

* Flush tracks now account for more than 70% of total IDSystems installations - but they are still relatively rare for existing doors and older homes.
* As flush tracks require higher technical precision than traditional thresholds, without expert guidance, this can unfortunately lead to mistakes that are costly and time-consuming to correct.
* Having worked on over 40,000 projects, [https://idsystems.co.uk/blog/idsystems-named-grand-designs-premium-partner/ Grand Designs Premium Partner IDSystems] has been at the forefront of mastering these complex installations since their inception.

Below, Stobart explains why installations still go wrong, and how mistakes can be avoided.

== #1 Not understanding which types of doors can achieve a completely flush track ==

Sliding doors and slide & turn doors can be designed to achieve a flush finish with a solid weather seal, but most other doors such as bifold and french doors need at least a low threshold to seal against.

Knowing the difference can make or break your project. Below, there’s a summary of considerations for a range of doors, but if you’re still unsure, you can find more details on [https://idsystems.co.uk/blog/flush-track-mistakes-to-avoid/ the IDSystems site].

35mm upstand, for more exposed coastal and rural conditions

Bifold and French doors close into the track or upstand. While it is possible to purchase completely flush track bifold and French doors with no upstand, in those instances, the only connection between the bottom of the panels and the track is brush pile, which is not an effective method of preventing drafts and rain.

Stobart advises against opting for bifold doors or French doors with no upstand, saying: "These were common-place when folding doors first became popular but with only brush-pile sealing the base of the panel to the track they are incredibly prone to drafts getting in and even water ingress. Completely flush bifold tracks should only ever be used for internal applications, for external doors you need an upstand against which the panels can close to create an effective seal. We get customers who have their hearts set on the completely flush appearance, but when we explain the risks and that the low-threshold track is only 14mm, they understand.”

This doesn’t mean you need to compromise on your flush track dreams. Bifold doors can be manufactured with tracks that are designed with a small 14mm upstand, against which the panels close. This upstand is barely noticeable, complies with [https://www.gov.uk/government/publications/access-to-and-use-of-buildings-approved-document-m Building Regulations Part M] for wheelchair access, and still appears to be almost completely flush when viewed from inside and out.

== #2 The flush track is too high ==

The most common mistake when trying to achieve a flush track finish is the track sticking out above the flooring. Unfortunately, this is also the issue that is usually the most difficult to fix. Stobart explains: “Typically, if the track is too high, it is because the base has been built up too much. To fix this issue, it would have to be lowered by digging out the base and reforming it to the correct height.

“Unfortunately, this is time-consuming and, more importantly, will have a knock-on impact throughout the rest of the ground floor of the finished floor height.”

“For a new-build, this may be possible, but for an extension where you are likely to be matching the floor height of the existing house, it is far more challenging. If it is not possible, the likely result would be the track sitting slightly above the level of the finished floor.”

== #3 The flush track is too low ==

Stobart explains: “When the track is too low, we have the potential ability to pack underneath the frame to bring the height of the track up to match the finished floor level.”

“However, how much it can be raised is dependent on the size of the doors and the tolerance allowed for at the head of the system.”

If you want to raise the bottom track, the entire door panel has to raise with it. There is a certain amount of tolerance at the top of the door to allow for smooth operation and small changes in structural settling of the building over time. It’s not possible to raise the track beyond the tolerance of the system without changing the size of the opening.

== How to ensure the perfect flush finish ==

For Stobart, successful flush track installations come down to one thing: precise measurement of the system, opening, and finished flooring: “The biggest bit of advice is to know the depth of the track for the system you are installing and to make sure that is accounted for when the size of the doors is ordered - especially if the systems are being manufactured based on planned sizes.

“Where the opening is being surveyed prior to manufacturing it is crucial that the finished floor level (including the chosen floor finishes) are communicated to the surveyor so they are incorporated within the calculations of the aperture sizes.

“Almost every manufacturer and every system has a different track depth and ensuring that the base is built to the correct height to accommodate your particular door is crucial to the end result.

While the technical requirements of a flush track are more demanding than a standard threshold, the aesthetic payoff is undeniable. Stobart notes that because these systems require such high levels of precision, some contractors or builders may be hesitant to install them: “I was on site recently and the builder had originally tried to talk the client out of having a flush track because it meant more work and detail for him – but the client stuck to their guns and in the end the project looks so much better for it.”

“Just make sure you [https://idsystems.co.uk/blog/flush-track-mistakes-to-avoid/ do your homework on the technical details], and installing flush or low threshold tracks doesn’t have to be a headache, but showcasing your expertise can instead open the door for more luxury build work in the future.”

Innovative glazing supplier and manufacturer [https://idsystems.co.uk/ IDSystems] is celebrating its 25th year in business this year. The company was started in 2000 when founder Richard Hunter secured the exclusive UK rights to supply and install [https://idsystems.co.uk/bifold-doors/aluminium-bifold-doors/ SUNFLEX door systems] from Germany.

At the time, the term ‘bifold door’ was virtually unheard of in the UK, but had been used in Europe for a decade. Richard saw an opportunity to introduce the technology to the British market by founding a company that [https://idsystems.co.uk/blog/manufacturers-and-installers/ specialised] in these innovative systems.

One of the earliest employees, Carl Farrow, was originally employed as an administrator to answer the phones, send out brochures and make the tea. Today, he is CEO. He remembers the early days well: “If you told someone you worked for a bifold door company, they’d give you a puzzled look. We spent as much time explaining how the doors worked as we did anything else because nobody had seen anything like them before.”

“We’ve always said that we didn’t just build a company; we built an industry,” Carl adds. “Being so far ahead of what everyone else was doing back then undoubtedly played a huge part in creating the demand that exists to this day.”

By 2004, IDSystems began manufacturing its own products in the UK. Today, the company’s manufacturing facility in Rackheath, Norfolk, extends to almost 56,000 square feet, with nearly 70 staff based there.

CEO Carl Farrow highlights that their commitment to British manufacturing has been a cornerstone of the company’s success: “The skills and experience of the staff that have worked for the company over the years have been crucial in not only the finished projects, but also the design and development of cutting-edge doors and windows."

”More than half of the current staff have been here for more than 10 years, which is incredibly rare for the type of business that we are, but that shows real dedication and commitment to the business, to our customers, and to each other.”

Since its inception, IDSystems has continued to innovate, creating UK firsts for modern glazing: first in the slim frames of [https://idsystems.co.uk/sliding-doors/theedge2/ theEDGE] and then the UK’s first high-performance slide & turn door system with [https://idsystems.co.uk/slide-and-turn-doors/vistaline-slide-and-turn-doors/ Vistaline].

This influence on British home design has been recognised, with IDSystems being named a [https://idsystems.co.uk/blog/idsystems-named-grand-designs-premium-partner/ Grand Designs Premier Partner], in recognition of product quality, outstanding service, and product innovation.

Never a company to stand still, IDSystems is looking ahead to the next 25 years. “What we’ve always been really good at is being ahead of the industry,” Founder and Managing Director Richard explains, “The “ID” in IDSystems stands for Innovative Design, and we’ve never stopped trying to improve the products that we install so that we know our customers have the best possible doors and windows for their homes.”

To mark the anniversary, the Norfolk showroom is undergoing its biggest-ever transformation. The space is being completely reimagined to showcase the latest aluminium glazing systems and products to set home improvement trends for the next 25 years.

Further expansion is also on the horizon, with plans for a third showroom in Essex to better serve the thousands of customers in and around London.

From a small team to an industry leader, IDSystems’ journey is a testament to the vision, high-quality work and dedication of the people at its core. See [https://idsystems.co.uk/blog/idsystems-celebrates-25-years-in-business/ the full blog post on the IDSystems site] for more insight from Richard and Carl about the company’s journey so far.
