Grabex Windows Ltd Reviews 

My experience with Grabex has been outstanding . I could not fault them from start to finish . The communication from Matt was very good, the installation went without a hitch and the installers , Greg and his team were absolute professionals . Peter on sales was also super helpful . I highly recommend this company and will be having them back to do my patio doors .

Professional, friendly team that installed our new, amazing aluminium windows on time and with attention to details. Grabex Windows is a company I will definitely return to while continuing our period house renovations. I also liked the fact that we were advised not only what kind of windows we needed to keep in character with our original 1930's style, but also what works needed to be carried out to make sure the house will be optimised for the changes. Working with Grabex was like a breath of fresh air among the meanders of our lengthy house refurbishment! Bravo!

We can thoroughly recommend Grabex Windows who supplied and fitted our new glazed front door and two glazed side panels.

Greg was our initial contact and was very helpful through the design phase, which included a tour round the factory. Lukas was proactive and clear on the survey, Richard and Phil did a great job fitting the whole unit, and Matt in customer service coordinated everything well.

Must also give a big shout out to Hugh Wootton of Specialist Glass Company in Sidcup who created our three beautiful stained glass panels. Hugh was recommended by Grabex and works regularly with them.

This was a good experience - our sale consultant Marta Bouziane was very helpful and patient with us - the process was long as we have had to make a few changes due to unexpected design challenges. The installation was timely and professional.

I had double glazing windows installed in my period property apartment several years ago. I had a great experience from start to finish - quality materials, like for like design for period properly, and professionnel fitting. What made Grabex stand out is their customer service. I had an issue opening a window that had been closed for a while. Grabex were responsive in arranging a visit, didn't charge to fix the issue and provided a helpful tip on maintenance long term.

I had 4 windows and a door installed, replacing existing old windows with bad insulation.Grabex were professional throughout. I highly recommend.

Incredible service from Grabex from start to finish and very happy with my new windows and doors. A professional, dedicated team whom i thoroughly reccommend.

Great experience with Matt and Greg at Grabex. Everything completed on time and to great standard. Highly recommend!

Grabex dealt the windows order with by builders as btb deal. Property owners paid the builders for the windows. After works are finished, Grabex required the property owners to pay £150 + VAT to have the account under their name and said windows were provided without warranty whilst builders sold to the property owner a 10 years warranty. Property owners BE CAUTIOUS about this mechanism which will screw you up.

I had windows and doors change in my home . I'm very please for work you have done. Igor and Dorian were extremely helpful , professional and hard working people, very positive and cherfool . They work longer to get job done with one short break through whole day.
Menager Mariusz told us how to protect windows and doors. Hi provide us with silicon spray for locks and seals.
Thank you Grabex .

We had some really lovely bifold doors made and fitted by Grabex about eight years ago. They were not the cheapest but we love them and have been very happy with them. A few days ago, we started having trouble with the lock. I checked my paperwork and we had a 10-year guarantee. I got in touch with them, and they couldn't have been more helpful. A day or two later, their chap Richard turned up and fixed the doors (no charge). Really impressed.

From the initial enquiry through to the installation the service and attention to detail from GRABEX has been everything we could have hoped for. As for the windows and additional work? amazing value for money and such a worthwhile investment. Thank You!

Follow up visit from the team at Grabex to service my beautiful sliding doors. Prompt, efficient service with a smile. Nothing is ever too much trouble and you can rest assured that they provide really excellent customer care. 10/10.

We contacted Krystian at Grabex Windows to gather information, to replace our kitchen windows and bedroom windows on same floor.
He was excellent to deal with and very professional, as was Lucasz the Surveyor, and Matt (in office).

We finally had the paned "Georgian" style windows fitted very quickly from initial consultation with a great result!
We would recommend the Grabex window products and the very professional staff for windows!
Our new windows look great and we're very pleased with them.
Thankyou to all at Grabex (and to fitters Ryan and Scott)!
Excellent!

Krystian Brzozowski and his team were extremely professional in every aspect of the job. I observed good time keeping, hard work, attention to detail, polite manners and transparency throughout the work conducted on our house. Very happy with the new windows and door that was installed. Highly recommend their services.

We had rooflights, new windows and a door installed at the back of our house by Grabex five years ago. We were and remain really pleased with them. Recently we had a small issue with the lock on one of the windows and contacted Grabex. They quickly responded and within a few days the problem was dealt with. The aftercare service was efficient, friendly and professional, just like our dealings with them five years ago, and we will have no hesitation in using them again in future for further work.

Matt went above and beyond in his customer service. After our initial site visit the communication with the company was fantastic. They even called us back to discuss an alternative idea they had thought of which would make our home more secure. They didn't try to up sell us in fact they saved us money. They were very patient with us when we had a delay on our build and then fitted us in last minute so that we didn't have to have our house open to the elements. Would highly recommend this company and have now used them several times. Customer service 5 star

Thank you to Mario and his team who did a wonderful job installing a new glazed roof and window in my kitchen. Also, the office team, who were so helpful in getting my project sorted and done. Nothing seemed to be too much trouble. I am very happy with the quality and standard of work provided by Grabex and I will certainly be recommending them.

The whole team at Grabex were amazing from start to finish. Matt in customer services and the installation team were great to work with. Our bifold doors are beautifully made and everyone comments on how amazing they are. We will definitely use Grabex in the future.

Mario went above and beyond
