Fantastic service! We ordered doors from Grosvenor last year, over which time there's been a few problems (leaky windows - which were the manufacturers fault, not Grosvenors) - in all that time they've come out time and time again to sort the problems. They're a great company to do business with and I wouldn't hesitate to use them again because I'm confident that if anything went wrong, they'd always sort it out.
Superb - I wish all companies were this reliable.
Aug 2019 - The only thing I'd add at this point is I'm waiting for a window unit to be changed - I'll keep this review up to date

I thought by paying over the odds I'd be getting a good service. How wrong! I have never had dealings before with such incompetence. I had Windows and a palladio door fitted by Grosvenor 3 years ago and experienced a a series of inexcusable mistakes.
Firstly, they fitted red beveled glass in the front door and blue in the Windows!
Secondly, despite ordering obscure glass for the bathroom they fitted clear, as I live on a main road this was totally unacceptable. When they replaced the glass it was fitted back to front. After being shown an impressive and attractive roof in the showroom we ordered

GREAT SERVICE .. 20 YEARS AGO! My parents dealt with Grosvenor 20 years ago when they replaced the complete set of house windows and patio door (9 or 10 units). We couldnt fault them in terms of quality of product, price, or service.
However, as can often happens when the original founding owner hands over the reins to the next generation, things can start to change and, in many instances its not for the better! This is very much the case with Grosvenor.
Ive dealt with them a couple of times in the last 3 4 years and its been OKAY, prices were high but the service
