db Designs replaced our windows and doors and did a fantastic job. Dom was professional and friendly and cared about the end result. The installers were equally brilliant, professional and trustworthy. I would fully recommend db Designs to anyone wishing to replace their doors and windows.

Caution - Good at selling but not Post Sale…

Good at selling but watch out if you have an issue!

Pls watch these guys about warrantees and guarantees because once installed - they do not care. They present issues, blame and hide behind warrantees should later problems arise with the installation.

A considerable amount of work and huge expense was previously undertaken on the entire house we then purchased - 25+ doors/bi-folds windows , lanterns etc - anthracite grey.
DB obviously provided a competitive quote to get the job.

An issue was raised with the rubbers and seals, that was batted off as damage caused by the owners.

The Lantern glass shattered in the heat and exploded over the back of the house, no apology despite being a serious potential accident - was told glass is no longer under warrantee.

UPVC coating has also degraded in sunlight into an ugly pale grey and white faded mess - on a period property with a lot of windows! It has devalued the house and ruined the aesthetic.

Despite being under warrantee we were then told the UPVC coatings also have a shorter 5 year expired warrantee for UV fading specifically.

DB's manufacturer (DirectTrade LTD) insisted that the windows must have been cleaned with chemicals (not true at all - only windows exposed to sun have become chalky - all would be affected if due to 'so called' chemicals) no proper assessment or testing was done, an assumption made.

For example: we have one window that is half shaded and half in the sun - the half in the sun has gone chalky - the shaded side has not - same window - different light - all washed with purified water. The huge lanterns in the extension or now virtually white instead of anthracite. That must because I climb up onto my roof regularly with my chemicals right?!

I have installed anthracite UPVC in a couple of other properties which 11 years into their lifespan DO NOT LOOK LIKE THIS.

Despite explaining in detail , no site further visit was offered, no pictures asked for , we have to remedy these issues ourselves. The costs to respray unsurprisingly run into tens of thousands.

We are seeking legal advice.

3 reputable quotes from established UPVC experts and EVERY single one commented that the level of degrade is the most severe they have seen and synonymous with a UV defect in the paint applied or an error in application .

DB and their window supplier disagree quoting 'sorry about the UV stability but this does occur on painted plastics I have seen it many times'. I suspect this is not a statement shared at the point of sale.

Any poor trust pilot reviews here say exactly the same - after care issues and support is nil - warrantees are blamed - repairs and issues avoided - so proceed with caution if you want an installation that will last more than a few years and good post care if something fails or is faulty.

Check warrantees and make sure you read them carefully! 10 years only applied to a few things so exposes the customer to lower warrantees where they probably need it the most. Good for DB but not for the customer.

Or, avoid and seek an alternative company, especially if significant home improvement investment is required for your project.

As you can see by the comments below they continue to defend highly faded windows without so much as an apology.

The previous owners stated once in an email their cleaner had used fairy liquid and focused on this as the entire reason for fading.
My question to them still remains unanswered weeks later…..
A cleaner does not scale. 15 foot ladder to clean upstairs or lanterns so why are these the same appalling degradation as those within a cleaners reach.

Still no answer to us, but have taken time to respond here with more excuses about what shade of grey they are? Lol

Several neighbours have expressed similar poor service concerns. This is not an isolated incident.

DIrect Trade their window supplier also has poor reviews.

We installed for the previous homeowner 9 years ago Iron Grey PVC which comes with a 5 year guarantee we did not install Anthracite Grey products.
If this was the case it would of been Renolit Foil which comes with a 10 year guarantee.
They were ordered as RAL colour 7011 which is Iron Grey and sprayed therefore a bespoke product and colour that comes with a 5 year guarantee.
You say they have been cleaned in pure water but we do have in writing from the previous owner that chemicals had been used.
Frames in direct sunlight will have colourfast issues due to UV stability faster than non sunlight.

DB Designs is my first choice for windows and doors.

DB Designs is my first choice for windows and external doors. Over the past years I've had a new front door, back door and maintenance to my existing double-glazed windows. Quick and efficient with good communication regarding install days and times.
DB have also installed new doors and windows in my parents house locally. For an efficient and helpful service at very reasonable prices, I always recommend DB Designs.

Installation of window and external door

DB Designs recently installed a new bathroom window, fitted an external door, and repaired my balcony — all at a very reasonable price. They were incredibly flexible with scheduling and gave me full reassurance that everything would be completed before my bathroom installation works began, which took a huge weight off my mind.
The team finished all the work within a single day and left everything clean afterwards. The workmanship is solid, communication was easy, and the whole experience felt smooth from start to finish. Highly recommend DB Designs for anyone looking for reliable, efficient, and well‑priced home improvements.

Great service from the db Designs team

We needed to replace all windows, rear doors and front doors to our property and went with db Designs after getting several quotes. We immediately liked Dominic and it was clear he was experienced and had excellent knowledge, along with being personable and a pleasure to deal with throughout. He guided us through our selection with helpful insight and we are delighted with our new windows and front door. The x4 strong install team did a great job, notwithstanding the weather was terrible the first day they were here in nonstop all day lashing rain but they literally rolled up their sleeves and got on with it doing a great job. A small issue was quickly rectified by Dominic so no problems there and he was always easy to get hold of and responsive when we had further questions. We are very happy and would recommend and use again in the future. Thanks db Design!

Fantastic service and products

Really good service from start to finish and nothing was too much for them. An experienced team of fitters, net and tidy and did what they said they were going to do WHEN they said they would do it. Other contractors take note. A joy to deal with and i recommend them to anyone with glazing needs.

Dom and Sally are lovely people to do business with and I would not hesitate recommending DB Designs based on their work undertaken both for our church building and our home glazing.

Apparent lies about guarantee. Good service until you have an issue.

DB was recommended to us. Initial meeting and quote was good and Dom was courteous and professional. A year later our lock failed and we needed emergency assistance. Dom was on holiday and asked us to contact his fitter. Two weeks later and still no reply from them. We engaged a third party to replace the lock. This is where the company appeared to show its true colours. It's washed it's hands completely, stating a one year guarantee for door furniture. A quick look on Yales own website shows a 10 year guarantee on our lock. In our correspondence not once did Dom apologise for the lock failing. He has hidden behind a false one year guarantee. I would recommend any future customers look beyond the initial good impression of the company and consider the lack of support or common courtesy delivered when thier product fails. There is absolutely no after sales service, only sarcasm and abruptness.

Top class experience throughout from initial quotes through to installation (undertaken in two phases). We are extremely happy with the finished product and would have no hesitation in recommending DB Designs/Dominic and his team to others.

Delighted with our new windows

DB Designs were very responsive to our enquiry. Great choice of windows and doors at a reasonable price. They were very informative, open and honest. The fitters were highly skilled, hard working and very polite. Very happy with the new windows and glad to support a local business.
