Thoroughly recommend

Grabex were great at every stage of the process - friendly, knowledgeable and professional throughout. The three sash windows they installed for me are of a very impressive finish, and their team were efficient and tidy too. On top of all that, they were also very reasonably priced!

New replacement windows…

Have received 3 new replacement windows today. Very pleased with the products and installation. The team were great and were happy to make good even where they didn't need to i.e. assisted in putting curtains and blinds back up etc. Very tidy, cleaning up and hoovering inside and out. After two separate installations would continue to recommend this company!

As a customer during the covid pandemic I'm more than happy to recommend Grabex. They have installed double glazed timber sash windows to the front of my property and bifold doors on the rear.

quality of product is high
installation quality is high (I did have a couple of minor snags on the bifold doors which Grabex have resolved)

yes there were delays due to Covid, but nothing more than expected.

BEWARE DO NOT ORDER UNTILL YOU READ MY REVIEW

BEWARE
WORKMANSHIP APPALLING , COMMUNICATION WORSE , TIME KEEPING INEXCUSABLE AND AFTER 30YEARS AS A DEVELOPER I CAN TRULY SAY THS COMPANY IS SHOCKING.
REGARDLESS OF COVID , GLASS DELAYS AND STAFF SHORTAGES THERE IS NO EXCUSE FOR A SUB STANDARD INSTALLATION REQUIRING MANY RETURNS TO CORRECT MAJOR ERRORS AND A TOTAL DISREGARD FOR APPOINTMENT TIMES.
THIS IS AN HORRENDOUS COMPANY HEAVILY UNDER STAFFED BY THIER OWN ADMISSION AND STRETCHED BEYOND COMMITMENTS COMPOUNDED BY THE FACT THAT YOU HAVE PAID 100% IN ADVANCE , I AM HAPPY TO PROVE ALL MY COMMENTS WITH PROGRESS PICTURES LEADING UP TO AN INCOMPLETE “FINISHED” INSTALLATION WITH THE SLIDING DOORS SO TIGHT MY WIFE CANNOT USE THEM , END CAPPINGS MISSING TO MAJOR SECTIONS , GASKETS FITTED INCORRECTLY AND NO ATTENTION TO DETAIL.
IN ADDITION THIER FITTERS CRACKED A NEIGHBOURS ROOFLIGHT !
I COULD BE VERY VERY UNLUCKY , BUT WHEN CONSULTING WITH OTHERS IN THE DEVELOPMENT WORLD COMMUNICATION APPEARS TO BE A MAJOR FLOOR AND COMPLETED WORKS ALWAYS PROBLEMATIC

MY COMMENTS ARE FACTUAL AND TRUE , I HAVE NOTHING TO GAIN FROM MY HONEST PUBLICATION

Update (Part two)
The Grabex MD never did contact us and it took a further five man days to correct the faulty installation including removing the sliders base track as it had been installed incorrectly causing the doors to bind.
The installation still leaks and the Commercial manager is now not returning calls - no surprise .

I will keep reviewing until a satisfactory conclusion .

DO NOT WASTE YOUR MONEY , SATISFACTION IS NOT A GLOSSY BROCHURE AND FALSE PROMISES .
IT SHOULD HAVE SIMPLY BEEN THE PRODUCT AND SERVICE THE COMPANY PROMISED , REGRETTABLY NEITHER HAVE MATERIALISED AT GRABEX.

Andrew, Karen,

We understand your frustration. Glass delays and a slower supply chain of our components had an impact on many of our projects and we’re dealing with each and every one of them, at the same time dealing with the shortage of staff - unfortunately not due to our own doing.
Your project is our priority and, just to assure you, we are in the process of replacing your neighbour’s glass. We have encountered many unusual problems during your contract and we deeply apologise for the unnecessary stress it caused during the build of your home.

Please be ensured that all snagging will be resolved to your satisfaction and our Managing Director will be in touch with you directly to make sure all outstanding works are completed.

Outstanding windows, excellent instillation customer service.

We are so happy with our new windows – it’s one of the elements of the house which we love the most.!

We have recently renovated our home in Surrey and spent quite some time researching various companies and different options. We chose engineered hardwood from Grabex and visited the factory before committing – The level of craftsmanship clearly showed and we were particularly impressed by the in-house specialist paint spraying facility.

The acoustic glazing alongside the high quality of the frames and the skill and setup Grabex has, has resulted is a huge drop in noise from the road to the front of the house. :-)

Everyone we have had contact with at Grabex have been excellent, from our first contact all the way through to the outstanding instillation – Thank you!

We would just like to say Richard and his brother from Grabex did a great job installing 5 windows for us. They worked very well, were professional, polite , neat, clean and very tidy.
We would like to thank Grabex for a great installation with which we are very happy.

Terrible customer experience

I would like to echo the comments of a post made on the 13th December 2019. We were also met by a very friendly sales person who sold us a set of Bi-Folds.

Grabex were very quick to take our money (the full amount and a very considerable amount that has taken us years to get together) and then the problems started.

Doors were promised two to three weeks from receipt of payment and never delivered. All of our building works were based around receipt of these doors and had to be put on hold. We chased and chased to find out where our doors were, and received no reply and no updates. When we finally got a response they simply blamed their supplier and hung up.

When the doors finally arrived 4 weeks after they were originally promised Grabex only provided one delivery driver who was unable to get the doors out of the van alone and couldn't deliver them into the house unless we assisted in taking them off and carrying them through. The weight of the frame was extremely heavy which resulted in the corner of the frame getting damaged and serious injury to my foot.

We were told this was our fault and that Grabex delivery doesn't include taking the doors out of the van and delivering them safely in to your home. To quote the delivery driver "I could have stayed in my van and just told you to take them off. That's what Grabex will say if you complain". There was also a suggestion that it was our fault for ordering the frame in one whole piece rather than in bits.

I will be picking this up direct with Grabex but doubt they will answer my calls.

I wonder how well the skip delivery industry would do if they adopted a similar approach?!!! I wonder what would have happened if there was no one physically able in the household to carry the doors in? Do Grabex solely provide a service to those able to lift a metal door frame that I imagine weighs well over 100KG? Should they be advertising themselves as a service only suitable for bodybuilders? These are all questions I would be keen to get the answer to, however now they have my money, I doubt I will.

Perhaps we were naïve to not insist they have someone else come and help unload the doors. We had just waited so long and were desperate to continue with the works to our first ever family home. Perhaps we were naïve to think that a door company might relish feeding in to that experience with the hope of repeat business in the future.

I remember thinking Grabex was an unusual name for a door company when we first started with them, but now I get it. They were very quick to GRAB and take our money..............and then they EXIT.

Dear Will,

We have received the account of the events that took place during the Friday delivery and the photos of the damage to the frame.

I’m really sorry to hear that your expectations were not met, at the same time I’m obliged to refer you to terms and conditions attached to the order and the email confirming delivery to your address - both clearly stated that it is the responsibility of the customer to arrange for suitable labour and equipment to offload the items and carry them to the site.

Our driver should decline delivery in your case but instead, seeing you were not prepared to take this delivery, offered his assistance. He decided to help you to not only offload all the items, but carry them into the kitchen as you were on your own and could not have managed. During all that time he witnessed your verbal abuse and outbursts of anger, while remaining calm.

Your bi-folds were made and delivered as fully finished frames - as ordered, and you declined the use of our trolley, choosing to carry them to the back of the property. As a result bi-folds were dropped, dragged and scratched by yourself. May I remind you that we have images of those scratches and that our driver offered to return to do a touch up once installed.

I’m not sure what your comments regarding the skip delivery industry are referring to. I can instead point you in the direction of many other home improvement companies that deliver bulky items - new bathrooms, new kitchens or furniture - the terms are always the same kerbside deliveries only, and the customer needs to arrange for suitable labour to offload and carry items to site.

With regards to lead times - these are estimates only and should not be deemed as definite delivery date. We always advise our customers not to schedule any installation until goods are delivered and checked by them. You received all that information at the point of order. Despite our best efforts to get the orders as soon as possible, some of our component suppliers remain affected by current conditions.

I understand that buying bi-folding doors was a big purchase for you, as it is for all our customers, and we hope that they will be a great feature in your first home. Should they turn out to have manufacturing defects - they are covered under a 1 year supply only manufacturer’s guarantee, therefore we all find your comments implying we’re not interested once having taken your money quite upsetting and damaging to our business.

You stated it has taken you years to put together money for the bi-folding doors, therefore it’s difficult for us to understand the level of recklessness displayed on delivery - why you did not apply the proper amount of care and due diligence to the items that, as you claim, were such a considerable expense to you.

We will be reaching out to you, to clarify this situation, and making sure you’re satisfied with the product, so there’s no need to make any further edits to this review, as an example I highlight the comments about your injury which was not mentioned in the original review, then you edited to mention you big toe injury which now, in another iteration of your review, escalated to a serious foot injury. We all wish you a quick recovery if this is the case. However, despite few attempts at some humorous remarks, your account of the events makes us think you’re not entirely truthful and honest in your review and only seek further gains for yourself at the cost of damaging the reputation of a small business.

Good quality wood framed doubled glazed windows

We have been impressed with the knowledge, suggestions and support throughout the sales process. Greg Kowalczyk was very friendly and helpful.
We are also very happy with the quality of the windows themselves and the fitters were very courteous and professional.
We would happily recommend Grabex.

Great Bi-Fold doors

Great company to deal with as I ordered the doors with internal blinds myself. Not being in the trade the Lady I dealt with was excellent and talked me through the process. She was also extremely helpful afterwards with my questions. Would highly recommend.

Find someone else

Let me start with positive: very pleasant sales person and easy to arrange a date to fit the windows, from there is a long painful journey, appealing customer service, no replies, no phone backs. still stuck with not finished windows/doors, have tried to ask for owner's email address but have been told to contact service team again. will never use them again and will make sure none of my friends as well.

Very good product, recommended!

We changed all of our garden doors for new ones made of timber, and we are very pleased with the product. The new doors look beautiful, the installers were professional and well mannered, prices were competitive and everything went smooth. I have had a very good experience with the team at all points of the project, from providing multiple options/quotes to the installation. I wish I had done this work earlier and would definitely recommend Grabex. Thank you!

I’m a returning customer and didn’t even consider any other company to supply and fit our new windows. We were given all advice regarding the thermal efficiency, fire escapes and design. There was no hard sales and the overal price was very reasonable. Their surveyor had wealth of knowledge and experience. The fitters arrived on time and did a truly great job. We had a friendly chat, they were helpful and tidy. The new windows (including 2 big bays) have really enhanced our house’s look. It’s worth mentioning they manufacture their products and can really offer a wide variety of products, colours and materials. Highly recommended

Quality products and great customer service

I can’t recommend GRABEX enough. If you’re looking for quality products and great customer service, look no further. We had two bay and two casement windows installed. The surveyor helped us enormously to get it right with design, openings and vents. We didn’t wait long for the installation - not to mention fitters came on time, were very polite and knowledgeable and did a fantastic job. The windows look lovely and really made such a difference.
They have got a impressive choice of products, designs and materials to suit every style and budget. No hard sales. Great customer service, prompt replies. Highly recommend!
