Professional service, excellent product

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.

Recent aftercare experience

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.

Very professional and friendly with brilliant result

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.

Appalling after sales care

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.

Dear Susan,
We tried to assist you with correcting the installation conducted by your builder, and pointed out a number of installation issues which exist and have not been addressed. So far we have not been provided with any report or evidence of what you believe the actual manufacturing fault is.

The facts are:
- The french doors in question were purchased as a supply only, collected from our factory in 04/21, and installed by your builder at a much later date.
- On 1/3/22 you reported the leak and the issue with rubber seals and we offered to inspect your installation at a small fee.
The site inspection was followed by 2 free of charge service visits 8/02/22 and 8/08/22 where we changed rubber gaskets, adjusted the doors, changed and adjusted drip bars, installed missing keeps and caps, and drilled missing drainage.
- On 5/04/23, following the report of the leak appearing in the room below by the new owner, our installation manager inspected the doors and the installation (free of charge), conducted the water test and found no fault with the doors, nor its drainage, however pointed out to number of issues he identified that might be causing the leak, amongst them the way the cill was fitted and drilled through, fixing screw holding bottom threshold which could let water in, missing silicone, frame not correctly joined with he coupler, and also insufficient tanking/ weatherproofing in the areas of the balcony.

These are all installation-related issues which we advised you to address by refitting the frame, which would also allow you to look further for water ingress.

- We advised on the independent RISA inspection, should you be not satisfied with our findings, as this type of independent report firstly is admissible if needed in court and secondly if the report does find fault we will act on their reported findings. The RICS report you procured instead, and only recently shared with us, unfortunately covers only visual inspection, and even refers to an entirely different system ‘patio sliding door’ not the french door in question. Unfortunately we can’t comment on other reports you mention, as their findings were never shared with us.

- We also prepared a quote for reinstallation of the doors, which would also allow us and you to inspect the threshold and check for the cause of the leak, but the offer was declined and on 16/10 - your case was escalated to our general manager who responded in depth to your email pointing out unsuitability and mistakes in the RICS report.

We’d also like to remind you of the GGF conciliation scheme and alternative dispute resolution (details of which are in the terms of our contract) which is at your disposal, if you’re not happy with our findings.

Thank you for your comments about our timber sash windows, we’re glad to hear you’re pleased with them. It’s a shame you’re not willing to address our findings.

A fabulous experience is the only way…

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 wonders

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.

Cracked window

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.

Dear Marianne,

We stand by the quality of our products. And we're really sorry to hear of your dissatisfaction,

Our guarantee covers replacement of a glass unit in case of a sealed unit failure, which includes fogging up, gases dissipating, internal condensation. Unfortunately we cannot give a warranty for breakages, including spontaneous breakage, and these are the standard terms across the industry. This could however be covered under your house insurance.

We inspected the breakage, and as a gesture of good will, we offered the unit at cost price to us (as we don’t manufacture them) and waived the charge for a service call. We've done everything we can reasonably do to help you in the situation and we're sorry we cannot meet your expectations.

A top quality customer experience

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

Positive experience

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.

An Exceptional Company

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.

Great sliding door and customer support

Grabex installed an aluminium sliding patio door as part of my house renovation.
I did some research prior to engaging with suppliers and the Reynaers door brand made my shortlist. Grabex is a Reynaers supplier local to me, so I booked an appointment at their showroom. The salesperson was helpful and I felt like I'd made an informed choice on the CP130 Lift & Slide model of door, with its almost flush track.
The next day a quote arrived in my inbox, which was drawn up professionally including diagrams. After visiting other showrooms (with products from Reynaers competitors), I decided to move forward with Grabex as I liked the CP130 out of all that I'd seen, and the lead time to installation was about 10-12 weeks, which suited my project.

After paying a deposit, I was contacted about a week later to arrange a survey. There was a 2 week lead time, for a total of 3 weeks after paying the deposit, which at the time made me feel a bit nervous about whether my expectations for installation were optimistic, but in the end it was completely fine. The survey was very comprehensively and professionally carried out. This came back a few days later as there was an issue processing it, but it was specific to my case and I don't expect it would happen again so I won't knock Grabex for it as after some phone calls they did sort it. The customer support team were very good at trying to get my case advanced - Lindsay and Matt were two very helpful members. When I did get the survey paperwork, it was second-to-none in terms of design and specification, and gave my builder what he needed to prep the aperture.

A few weeks later I was offered an installation date, which was about 10 weeks after I paid my deposit. On the day, the fitters arrived and very quickly installed the door. If you've had a builder do any prep for you, it's best that they be around in case they need to do any finishing off of the aperture, as mine had to because he hadn't quite made it ready properly (no fault of Grabex). The Reynaers CP130 product looks beautiful in the space and I'm very happy with it.

A couple of hours after installation, I noticed that I was unable to lock one of the doors as the handle wouldn't rotate up. I emailed and called Customer Support and Matt was straight on the case, able to get the fitter back round in the afternoon to have a look as they (rightly) didn't want me to be without a lockable door overnight. I suspected that the sliding door frame was settling in to the wall and probably just needed adjusting, so I wasn't too concerned, but was glad it was being taken seriously. The fitter returned and quickly disassembled and reassembled the door so that it sat better, which fixed the problem completely.

Overall my experience with Grabex has been very positive, and I would use them again. There were a few niggles in the process that could be improved, especially in terms of communicating next steps at each point along the order process, but there was always someone I could talk to and overall I did get a door installed in 10 weeks, which I believe is on the faster side of average for the industry, plus the customer support team are brilliant when you arrive into their care, so I would still rate Grabex 5 stars.

Fab French doors, great service.

Really pleased with our uPVC French doors. The grey exterior we chose looks very smart and the installation team were super efficient and polite. Excellent customer service kept us informed all the way through although it would have been good to have a video call to go through the options as it can be hard to choose just from the brochure info alone.

Professional firm represented well by sales, technical and support staff. We ordered the SL68 aluminium windows which offer a good ratio of glass to frame, so letting lots of light in. Installers took 2 days for 7 windows, working diligently and without compromise.
