We had a lantern and a set of sliding doors installed at our property in Henley in April this year…read more The job itself was quite good, all completed in a week, with good communication. However, upon completion of the work we realised the installers had damaged our natural oak floor during installation. We raised this with WindowWorx who sent their General Manager to take a look. He verbally accepted liability and followed this up with an email, again, accepting liability. WindowWorx went ahead and got a quote for the repair work which was £2,500. Following this, the owner of the business asked to come and have a look himself, so we welcomed him in. He immediately started talking about getting the insurance companies involved to figure out whose liability it was, which was odd, as we'd already established this. Needless to say their insurance company sided with their client. They fabricated a story about us damaging the floor ourselves, with no evidence whatsoever. They carried out zero due diligence, they didn't even visit the property, they just palmed us off. We have evidence by way of photographs that the floor was undamaged before they carried out the work, and damaged once completed. We took legal action against WindowWorx (this is their trading name, the limited company is actually First Direct (Kingston) Ltd) at significant cost to us, but again, we were palmed off with the same letter we'd received weeks prior from the insurance company. It was simply too expensive to continue perusing the matter in the courts, so we just had to walk away with a massive loss and a damaged floor. These people are not kind, they're not honest - they are deceitful and they lie. I would avoid them at all cost.

I am delighted with the windows provided and fitted by WindowWorx. There was no hard sell - rather…read morea team of people who listened to what I wanted, and gave clear and sensible advice. The cost was extremely reasonable compared to others, and there were no hidden extras. The finished product is excellent and I have received positive comments from neighbours and visitors alike.

High quality windows and doors fitted expertly with minimum disruption and good finishing off. They…read moreuse their own people to survey and then fit the stuff, not contractors. When they quote, they will give useful advice and avoid any form of hard sell. They will also help you with ideas if you want them. They are concerned with excellence, and the designs and materials they use are chosen and fitted carefully, even when competing on price. You can also go down to their factory in North Street where they build your windows and get shown around. I found them to be straightforward, honest and friendly, and therefore a real pleasure to work with to get the best windows and doors for my house. They don't use clever techniques to confuse, or pressurising sales methods to get your business. In fact it was pretty-much a pleasure to part with the money at the end of the job. My fears that we would have a load of mess were unrealised and I'd have them again any time. So you know, because this is a glowing report, I have no connection with them - just impressed by their integrity and quality. By the way, they've been going as a family-run firm for about 30 years.

I got 2 windows fitted by this company a year ago. I am very…read morehappy with them. They did a good job, cleaned up after themselves and replastered around windows. they gave me a 10 year guarantee and because they are FENSA registered this will help if I ever sell my house within this time as the guarantee is transferrable to the next owner. I would get them to do further work if I need new windows in the future. As they are a local company, I know that the money goes back into the community and not out of it which would be the case if I'd have used a national company to do the installation.

Can't see that I would have cause to use anyone different next time I need windows. Highly recommend them.

I had a guy come around to the door to make an appointment for a quote (same day). I was told about…read morean offer of getting two windows done for the price of the one (bay window compared to simple window) and this quote being valid for 12 months. I was interested but not for right away. Very possibly though within the 12 months. The quote guy came around and gave me a quote. Not mentioning the offer. I asked about it and he gave me a new quote with the offer but this quote is only available if I confirm to the purchase right away. If this is not a pressuring method I don't know what Is. Friendly escorted the guy out (who rudely went on his phone while still talking to me). Great window product. Really bad company sales policy. Won't consider them for my replacements.

I was almost discouraged from using this company by a competitor, who came to provide a quote at…read morethe same time Grabex was installing for a neighbour, but I decided to get a quote regardless. The price quote was competitive, however the sales consultant was absolutely lovely and professional from start to finish, not pushy, provided required information to aid our decision making. On day of install, installers arrived on time, were professional, and did a stunning job. My partner and I, are very satisfied. The windows look great, and have dramatically changed the look of our home. We were also impressed by the Supervisor who came to check that the installation was progressing as planned half way through, Totally recommend, service and quality of windows is excellent. More companies should aim to be like Grabex.
