Windows and composite door fitted

“Absolutely thrilled with the work done I was a lift unsure using a company not really heard of before but no worries they are fab and an excellent price will certainly recommend this company and would definitely use again. Thanks lads xxx”

New front door

“The guys arrived at the exact agreed time, they were polite and professional. The work was carried out to an exceptionally high standard and the quality of the door is excellent. I wouldn’t hesitate in recommending this company. Well done guys and thank you.”

Windows with door and canopy

“Top notch workmanship. Superb finish and they even hoovered through the house. The suggestion of a canopy in one piece between window and front door is superb. All great blokes who know the meaning of a promise i.E. To provide the service they are payed for! I would 100% endorse their work and will be using them again in the future. Thanks for a superb job at the agreed price. We defiantly got what we payed for more in my opinion. They even took away extra rubbish and carried out a few repairs for free.”

“Work carried out to a high standard, very quick and efficient. Always kept in contact to let me know when the windows would be getting fitted. Excellent set of lads. Will be getting them back for some more work very soon.”
