Grabex Windows Ltd Arvostelua 

Grabex installed 3 windows for me a couple of years ago. I had some issues recently with one and contacted them and Mario came to service them and explain the issue to me and they’re hopefully back in good working order! Very helpful over email and in person- recommend !

I first employed Grabex in 2014. They have now replaced all the windows in my property. My opinion is they offer a very competitive price, for a high quality product with a 10 year guarantee. Their aftercare and customer service is prompt and exceptional. I have always been very impressed by those sent to resolve any issues. with special mention for (Manager) Mario

I recently had Grabex install new windows and a front door at my home, and I couldn’t be more impressed with their work. From start to finish, the entire process was seamless and professional. I’d like to mention Marta here, who took the time to understand my preferences and provided expert advice on the best styles and materials to suit my home.

On the installation day, the team arrived promptly and worked efficiently, ensuring minimal disruption. Their attention to detail was evident in the precise fitting of both the windows and the door. The finished product looks fantastic, enhancing both the aesthetic and security of my home.

I highly recommend Grabex to anyone looking for high-quality windows and doors with top-notch service.

Some 18 months after installation there were one or two minor issues with our double glazing and bifold doors. Everything was attended to immediately by the Grabex after-sales team and resolved without question - thank you!

Grabex staff - from the office and showroom to the surveyor and the installation team - were friendly, efficient and professional. Our windows were ready sooner than expected so the installation date was brought forward, and they look great! The only reason for not giving 5 stars is that we had an issue with communication when a staff member was on leave, but this was resolved quickly and efficiently when they returned to work, with profuse apologies. They were a pleasure to work with, would definitely recommend.

I am absolutely happy with the new windows recently installed in my property. The quality of the windows is outstanding, making a significant difference in both soundproofing and insulation. The team was punctual, professional, and completed the job on time, exactly as promised. Additionally, they have exceptional customer service - from the initial consultation to the final installation, they kept me informed at every stage and were always available to answer my questions. I highly recommend them for their professionalism, and top-quality windows.

Grabex were recommended by our builder, and they really delivered. Very professional and responsive in the design phase (thank you, Greg!). Detailed measurements were taken swiftly and different options for our aluminium doors towards our back garden were presented (incl. examples of recent installations), and when I wanted to make some changes after the measurements were taken that was no problem. Throughout the process they kept us up to date with clear communication and always reachable. The doors were delivered ahead of time and installation was smooth, by their friendly team. Really pleasant experience throughout, I can only recommend Grabex.

Be very careful when dealing with these guys. Original installation date was meant to be 18th April. This was then delayed a few times supposedly due to their glass supplier providing them with the wrong windows, and on 23 July they came on site to install the windows. Guess what? They installed the entire frames but windows didn’t fit!
this finally installed 2nd August.
Have left me to pick up the cost of 11 days of scaffolding rental (was meant to be a 1 day job), call out to fix the alarm system and the builders labour because they can’t manage their supply chain appropriately. You would think given their supplier gave them the wrong glass once they would check before coming to do the install.
Apparently not

Grabex put 3 UPVC windows into a London property of mine. I found the company professional in their approach and responsive to any points I raised. The result was very pleasing. I would definitely employ them again.

Grabex sell and install excellent products. We had our kitchen sliding doors installed nearly 10 years ago and they still provide fantastic customer service. Mario visited recently to check our doors and was friendly, knowledgeable and efficient. The doors still look great and function perfectly. I recommend them without reservation.

Great aftercare!

I have used Grabex a few times and they are very professional and reliable.

Professional and efficient services from various departments of Grabex.

From start to finish everyone has been professional, friendly and a pleasure to work with.

The fitters on the day were respectful towards me and my property, I was particularly impressed by the way they left the site clean and tidy.

Very happy with my new front door & have already recommended to family.

Very hard working and thorough installers . 15 windows and two doors installed in 3 days. One snag dealt with promptly .
Very good experience as a customer.

My experience with Grabex after care was extremely helpful. They went out of their way to solve the problem. I can recommend them. Their staff were particularly helpful particularly Richard who was the person who visited me.

Great company, proactive and fast, good in solving problems. Plus the windows look great

We replaced all of the old wooden sash windows in our house with new ones. Greg (sales team) clearly explained the options, the surveyor (Lukas) was very clear when explaining the installation process. We received regular updates during the manufacturing, and then the installation was completed extremely quickly and professionally by Patryk and his team. We're very happy with the results.

Terrible. Not recommended. Left huge holes around the installation, doesn’t meet specification for width, window height etc, fixed window is a “dummy”, which apparently “everyone” knows is a real window which is then screwed shut with cheap screws from inside the remaining fixtures, fittings are ugly and not shown on spec, silicon sealant clearly visible around door and window fitting - protrudes beyond in many cases - so simply left sitting on the wall, because everyone wants to see silicon gel, colours don’t match, paint gloss doesn’t match (apparently you have to know the percentage of gloss to do this).

First complaint resulted in a visit. Constructive engagement on visit. But no answers. Then referred to a more senior person - who stonewalled - simply refused to do anything or answer - until the day after this review was first published (to complain about the name of one of their team that I included).

I will update this review again should Grabex be willing to deal with the issues caused. So far, I only have emails.

Overall very satisfied. The installation process was very quick and smooth, they had to come back to finish some bits that they missed but I did a last minute change and they managed to do it very smoothly and without charging me.
During the process of choosing the windows prior to being made was a bit difficult the communication if I have to be honest but overall the final service was delivered good and good quality too.
