What Our Customers Say

I would just like to say Thankyou for your speedy and excellent service to my door lock

I would recommend you to anyone.

I just wanted to say a heartfelt THANK YOU! Your lovely engineer visited yesterday and adjusted the doors so they lock with ease, he was helpful in giving me tips/advice to follow in the future too.

I have been really stressed the last couple of weeks with these doors, and your help & care in getting someone out to me quickly is really, really appreciated.

Dear Daniel,

Thank you for looking after me when I placed my order for two windows. I thought your service, the price and delivery were excellent so thank you. I have now received your job confirmation sheets with details and diagrams confirming measurements are correct. I must say they are superb.

I am very impressed with the degree of excellence shown.

Window Warehouse are an absolute breath of fresh air and we will now be placing all of our window and door business with them.

Bifold doors are as popular as ever. Homeowners want to open up their homes, so as they flick through the home magazines, they see an extension with bifold doors opening out onto the garden and they want that look. We’re also seeing architects specifying aluminium bifold doors more and more on extension plans.

We’ve been a customer of Window Warehouse for about two years now and find them very good to deal with. They supply our windows and just over two months ago we ordered our first aluminium bifold door.

One of our recent projects was an extension to create a large living area for a customer. The architect’s drawings called for bifolds, so we installed the 4 pane aluminium bifold door. The installation was straightforward and the doors were easy to fit.

I’ve been ordering windows from other companies for a while but had problems with service. I wanted to try a different company and stumbled across Window Warehouse. Remi was my first contact with Window Warehouse and he was fantastic! Nothing has been too much trouble for him. He drew up all my windows even whilst trying to enjoy his holiday. He called me on the phone after work hours and he has done everything I’ve asked of him – fantastic member of staff. Only wish I could find myself a Remi to fit the Windows. Please look after this star as I’m sure other customers will be happy to talk to Remi.

“I will not hesitate to recommend you”

I recently purchased some bi-fold doors from Window Warehouse. The doors were installed but unfortunately it didn’t go as smoothly as hoped as the glazing beads were missing. I was told that the aluminium supplier had sent the wrong beads and that it would be an extra seven days until we could get them. This meant waiting another week until the doors could be finished.

You may be reading this expecting a complaint, but that could not be further away from the truth. I have dealt with Anni, Remi and the staff at Window Warehouse along the way and found them to be excellent throughout at keeping me informed. They have a great attitude and provide great service. I wanted internal blinds set in the glass but I didn’t like the external pulley system on offer. The team at Window Warehouse set about finding a mechanism that used magnets instead which I preferred and made everything happen.

As a customer I appreciate that things don’t always run smoothly but it’s how you deal with the issues that makes all the difference. Window Warehouse came round to my house and fitted the beading for glass and balanced all the doors. The fitter was polite, efficient and did a fantastic job beyond my expectations. He also gave great advice about looking after and opening the doors correctly and is a credit to the company.

The installer who fitted my doors has already placed orders from you for their customers which I think speaks volumes. I also will not hesitate to recommend you. Far too often customers are quick to complain but great service and an outstanding response to a problem truly deserves some credit.

Imagine Bi-fold Doors are what the market needed. In the past we have steered customers’ away from PVCu bi-folds, but this door is really refreshing and works great.

We’ve already installed three sets of the new doors. Two of which were installed in new build projects. The developers needed a cost effective option to keep in budget and as the Imagine Bi-fold door is modelled on an aluminium one it delivered the perfect look, especially in the grey foil finish.

The homeowners who bought Imagine Bi-fold Doors from us have been impressed at how well they rival the modern look of aluminium. They’re a good price, not clumpy or bulky and because of the flush-fitting, inline aluminium track, they’ve not got to worry about the mechanism getting damaged and still have the advantage of it’s an ultra-low threshold.

Window Warehouse has supplied us with Halo doors for 12 years, so when they launched a new range of bi-fold doors that claimed to be the most versatile bi-fold ever we were keen to try them. We’re glad we did because within a month of offering Imagine Bi-fold Doors, we had already sold 4 sets.

Bi-folds have become really popular over the last few years, but to be able to offer customers something new and different to the rest gives us the upper hand over other local installers. Many of which only offer standard bi-folds.

Customers like the streamline look of Imagine Bi-fold Doors. The PVCu frames are slim and we’ve had lots of positive comments about the larger panes of glass. Customers like that they don’t obstruct the view to the garden as much as some other bi-fold doors we’ve fitted in the past.

Our fitters like them as well! They are finding them easier to install. When we have fitted other types of bi-folds we’ve had to take them away again to make alterations and adjustments, but we haven’t had that problem with Imagine Bi-fold Doors.
