## In customers' own words
_Verbatim quotes from this trader's public reviews, each attributed to its source:_
> "Just wanted to leave a thumbs up here for this great company. No pushy saleman style, just straightforward measuring and explanation, choice in glass and quick responses to emails. Came when promised and hugely impressed me on the day. The two chaps who came were friendly and polite and worked like trojans, being at pains to leave the house weather-tight before leaving on the first day, when to my surpirse they managed to fit all four windows in place by 2.30 pm and popped back to finish the insides the next morning and were done by 10.30! Lovely windows! Look so good! Heartily recommended!"
> — Customer (5.0, via Checkatrade)

> "Very pleased with newly fited patio doors a new kitchen door. Neat tidy work and excellent quality fittings. Involved cutting out a lot of bricks but John and Andrew seemed to somehow keep dust and debris to a minimum. Delighted with end result!"
> — Customer (5.0, via Checkatrade)

> "This company replaced the roof of my conservatory and fitted a replacement window. Both jobs were completed to the highest standard by friendly and competent staff. The work included plastering and fitting lights. I have used the firm before for replacing windows and this gave me confidence to use them for the big job of the new conservatory roof. I have no hesitation in recommending them."
