Grabex Windows Ltd Reviews 

Arrived when they said they would to measure up and then fit ( which was not my experience of others ) Kept fully informed of progress of the manufacture after I had ordered Fitters were respectful and tidy in the property. Did not leave until they were sure I was happy with the results

Grabex are one of the best companies I have ever had to deal with. Firstly their products are superb but potentially more important, is their customer and installation service.
We bought a house in spring 2023 and after moving in we realised that our balcony was leaking into our kitchen below. After months of investigation I opted to change the design of the balcony doors in the hope that this along with a new fitting would solve the issue.
The quote and handling of the design was very very good and reasonable, I explained that the existing doors had a serious issue that was causing extensive damage to the property. This info was escalated extremely quickly, I had several calls and emails confirming details, survey was booked extremely quickly and an expert came out to measure and investigate.
Due to personal circumstances and the damage that was getting caused each time it rained, the Grabex team expedited the fitting, calling and emailing at every stage up until confirmation of the fitting date.
When you are parting with thousands in cash for doors/windows you want to trust the company you are dealing with and you do not need to worry with Grabex, these guys are the BEST.
I took a day off work to be around for the install to make sure all the contractors knew how important the fitting was - with the issues we had been having. There was no need, every contractor on site knew the backstory and issues with the existing doors. I honestly could have left my keys under the door mat for them to let themselves in.
A special thanks to RICHARD, Marta, Matt, RICHARD and RICHARD. A year of problems with leaks and a lot of stress on my family, all solved within a month of first contacting them. Highly highly rated!

We had Grabex install the glass roof in our kitchen extension. We had been told by our council that we needed to use triple panel glass which very few window companies had done previously, especially with glass roofs. From the moment we contacted Grabex they were amazing! They understood our requirements and worked with us to find the best solution for our needs, and the councils.

Matt, Peter, Lukasz and the team were so professional, courteous and respectful through the whole process. They even went above and beyond when our own builder refused to do some work that was his responsibility.

I can’t recommend Grabex enough. If we ever have to replace any other windows in our house, we will definitely use them!

Fantastic service. Highly recommend. Extremely professional. Extensive survey carried out and advised re best options.

I needed to replace my balcony door, and I’m so glad that I did come across Grabex. First of all they guided me through the different options at the showroom. Then they took the measurements to make sure that everything will go smoothly and without any issues. On the day of installation, Mirek and Amir came in fully prepared, they were very professional, they covered everything, and started the work. While they were on the job, the supervisor came in to make sure that everything was in order. After they were done, they cleaned everything and left the place as tidy as it was when they came in.
Regarding the door, I was a bit anxious that it might not be as what I expected. But now, I’m certain that it exceeded my expectations. The build quality is very high. It came in well balanced and the handle/locking mechanism is smooth and sturdy. The glass was as I wanted, eliminating the sound. And finally the draught problem I endured for long was finally over.

Very professional, well organised, excellent communication and good attention to detail.

Grabex fitted a curved window for us some years ago. After problems arising with the sealed glass unit, they have investigated the issue and Mario and his team have been so helpful in providing a solution and fitting the new unit. The aftercare team kept us updated on the appointment for the refit and Mario and the company were keen to work to make sure we were happy with the eventual outcome. We are pleased with the new unit and look of the window, thank you to Mario and the team.

We had our windows fitted by the most professional, kind and friendly group of Grabex employees. Mirek, Amir, Mario and Martin came over to ensure the tricky bay window installation went smoothly. Although there were surprises they were prepared and did a fantastic job! Thank you for your brilliant service. I cannot recommend Grabex more.

Grabex are a truly wonderful company to deal with. Mario and his team were fantastic at trouble-shooting and fixing our Hi-Finity glass doors following their electrical damage by lightening. They were positive, kind and professional throughout.

Great job at a great price. Very helpful when it came to problems with access etc. I can highly recommend Grabex windows.

We have used Grabex to replace all our windows and doors. The level of service we have received has been excellent, from choosing the windows through to installation and aftercare. Would thoroughly recommend.

We built a house. Grabex advised type of window/door and Grabex measured for a set of French doors. We fitted the doors.

Doors leak.

Grabex wanted to charge us £150 for coming to take a look & stated they would refund £150 if they deemed window was faulty!

Local authority Inspector, NHBC Inspector, RICS surveyor all stated doors fitted correctly & Grabex inspector did not state that the window was fitted incorrectly.

Grabex now asking for a RISA report (at another £200 + ) before they ‘supposedly’do anything.

Feel only option is court action next.

Shame as they also supplied us with beautiful wood sash windows but will never use again and advise others not to.

A fabulous experience is the only way to describe our interaction with Grabex Windows. Everything from the initial visit to their showroom in Orpington, through the consultation and design process to the delivery and fitting of our Aluminium windows was extremely easy and nothing was too much trouble. I can thoroughly recommend this company as a delight to work with.

Absolute wonder.
Well experienced, matured in their field, fine workmanships of Richard & Phil & Mario.

Richard arrived to troubleshoot my installation, and to my amazement, Richard was able to determine the issues surrounding my door mechanism, which was failing to open and let me out ! This issue was a major fault which Richard with Phil, professionally rectified by re- aligning the entire frame. A whole days job!

Richard is advanced in his skills, but also very ethical. Richard and Phil were both determind to fix my problem satisfactorily.

Mario, is also a wonderful Manager. All these Grabex professionals at my home, Mario, Richard & Phil are real DIAMONDS for Grabex firm.

Mario, please provide Richard & Phil their appropriate rewards for such obvious OUTSTANDING WORKMANSHIPS.

Richard & Phil most certainly deserve Grabex finest reward.

I am so impressed with the deep respect that both Richard & Phil and Mario, alongside their fine workmanship, and good eye for detail.

I HIGHLY and SINCERELY reccomend Grabex Windows Ltd because of these fine professional men.

Thank Richard, Phil, & Mario.

Grabex installed my window which cracked within less than a year. You can see the source of the crack is from an unexposed part of the glass (within the window frame border) so could not be caused by myself. Grabex refuse to put this right without charging me. They claim “Spontaneous breakage can happen at any point,” and therefore isn’t covered by warranty.

You need to be aware that if you use Grabex the window they install can spontaneously break and you will need to pay for a replacement.

I’ve asked them if they won’t stand by the quality of their products and they haven’t answered - says it all. Basically a big risk using because if the window breaks through no fault of your own, you are still on the hook to pay for a replacement.

Grabex provided us with a great quality Bifold doors and front porch glazing and door. Their service from start to finish was knowledgeable, professional and timely. Communication was great and re-assuring - especially as we were nervous about paying before installation as we have been let down multiple times by different trades before.

The installation was quick, with minimal intrusion or mess and the new glazing looks fantastic in situ.

Follow up after installation with guarantee documents and after care advice is also welcome. I have no hesitation in recommending this fantastic company to all and sundry

I had a very positive experience with Grabex Windows when replacing our windows! Good customer service and professional installation can make a big difference in home improvement projects like this. I would recommend Grabex Windows to others who may be looking for similar services.
Special thank you to Peter and Matt. I appreciate all your help.

Erika and I would like to thank you all, Greg, Matt and the whole team at Grabex for the work done.

Despite some hiccups and delays, the delivery is now completed, and we are very happy about the result.
Materials supplied and installation provided have left us very much satisfied.

Thank you
Stefano and Erika Tomas

Start to finish, the advice given was very good and thorough. No sales talk at all and no competition bashing unlike the three other companies we got quote from.

This is the third time I have purchased windows and or doors from Grabex including bifolds, kitchen and bedroom windows and an amazing made-to-measure front door with glass panel. Each time the service and customer care has been exceptional, from the initial survey and quote right through to installation and after-care. Everyone is so helpful, professional and caring. Not to mention the superb quality of the windows and doors. I cannot recommend this company enough.
