Catherine Woodward
Stewart and Stewart were available to provide a boiler service and gas safety inspection at my tenants’ flat at short notice when the company I had been paying into each month, for a call-out plan that should have covered this, let me down. Grateful to them for stepping in, liaising with the tenants and getting the job done without issue, and within the legal deadline, ensuring I didn’t breach regs. Easy and friendly to deal with. Wouldn’t hesitate to recommend them.
Farhan Rashid Qazi
Very professional and knowledgable. Clearly talked me through the vairous reasons that could have effected my radiator from heating up. Talked me through different options to try out prior to sending an engineer and thankfully one of the options given fixed the issue. Thank you
Michael Green
Lee gave his time to advise me that I did not actually have to spend money - his honesty and help there means that I will definitely use him for any future plumbing issues
Paul Crichton
Friendly, local and helpful. Fitted new boiler and rads in a timeframe that suited my needs. Tidy and good workmanship. Has been available at very short notice for emergencies.
Marta Ra
Fantastic service, incredibly helpful, speedy, professional and kind - just the kind of support needed at the best of times and especially during the pandemic. Can’t recommend enough. 5 stars and above!!
David Johnson
I emailed for a quote and sent a photo. After describing my issue I received a phone call from Lee who was able to advise me over the phone. He didn't have to do that because he got no business from it. Would highly recommend because that was honest of him. If I have any jobs which require specialist work in the future I will be sure to call them. Honesty goes a long way.
John McElholm
What nice guys! Offered me advice over the phone to sort out a problem at no cost which got me out of a hole for the weekend. Am pretty sure anyone else would have made a call-out of the situation!
Jimmy Lemkes
I would highly recommend Lee and his company. they have recently completed a job on my bathroom to replace all the flooring and shower. They were very quick to respond, professional and went out of their way to be helpful, including going out of their way to make sure the job was done well.. I can't thank them enough for the work they have done.
Ben Matthews
