Every aspect from the initial visit to completion of the job was faultless and professional: all concerned we’re helpful, considerate, communicative and highly skilled. I will certainly use them again and will unhesitatingly recommend them to others." > — Customer in Greater London (5.0, via Which? Trusted Traders) > "The work involved capping parapets, installing a new valley gutter with a higher gradient, relaying the roof with new tiles and replacing joists where necessary. It was done to the agreed schedule and budget. GWS stood out in that their quote was clear and were very happy to visit and explain any items of work or technical terms. We liked the fact that their was more than one generation in the family business, we dealt with Daniel who supervised the work and Gary who would be there for Daniel to consult as needs be. We were confident they fully understood the issues associated with our roof. Throughout the job they were happy to send us photos and respond to our phone calls asking after progress. We were please with the behaviour of their employees during the job and were impressed with the dedication and care shown by the skilled roofer who must have done all the tricky bits that mean the roof isn't going to leak. There were a couple of contingent items, which were spelt out and quoted for in the quote, regarding the potential support of the gutter and that it may have to be relaid with a higher gradient. We were consulted on these items when the roof was first uncovered, and decisions could be made." > — Customer in Greater London (5.0, via Which? Trusted Traders) > "I have no hesitation in recommending GWS and the Sparrowhawk family as a very professional and pleasant firm to deal with. They carried out two separate pieces of work for me during the Covid-19 lock-down. The first to complete work to rectify lead work on the parapet wall beside my loft extension, which had already started before lock-down in March. The second - once lock-down restrictions had been eased - to replace the felt covering on the roof of my shed in the garden. Both jobs were carried out within budget - and within the time specified in their estimates. As a firm, they are very easy to deal with. No problem in reaching them on either the phone or by e-mail. Surveys and estimates are swiftly arranged and given and dates for work to be carried out are met." > — Customer in Greater London (5.0, via Which?
