10 Windows and doors done right !
Posted 3 days ago
John and Archie did a great job, polite and tidy. Windows look smart and door too. They always kept me well informed too. Overall great guys they delivered on what they promised and were both professional and decent throughout. I believe mine are the 5th set of windows done on my road andI would have no hesitation in recommending them at all.Verified reviewerJob location: AL210 Ash

Nothing but praise for John and his son. Great guys who really know what they are doing. Great price, great products and nothing is too much trouble.

We are so pleased with John's work. He was professional, polite, and worked very fast. He communicated well and there were no issues. He turned up on time, on the day agreed and started work... He gave us a day-by-day plan, and finished on time. Critically, the installation is fabulous. The windows look great and the internal finishing is great with nothing for us to do afterwards. I would highly recommend and use him again. Thanks!!Verified reviewerJob location: AL210 Front door

John recently removed the old and fitted the new front door at our newly refurbished property and was a pleasure to deal with. Couldn't be happier with the finish!Verified reviewerJob location: WD6
