2 installs completed. Both old and in need of replacing. Two new white woodgrain effect Vertical sliders now double glazed in uPvc finished with decorative trims to suit the old character of the property. But being on a busy high street the Rockwool insulation used to make these more thermal and sound efficient definitely helped cure these problems. Then on the second install, a new composite door, cladding and new timbers were used to replace what were once rotten, finished in a fibreglass finish on the roof giving a minimum 20 years guarantee.

This here to me is a sort of iconic house. Situated in Beltinge it's passed by so much traffic every day, placed on such a busy corner. Which presented my first goal to help tackle the noise the old double glazing let in, then to give the new windows the character this cottage style house deserved, all finished off with Ogee trims externally to achieve this. Foam filled, sealed inside and out eliminated the noise and draft issues. So pleased with the way this install came out, helped hugely by the amazing owners! Thank you again to Kelly Scaffolding LTD

When I was first asked to look at this job to replace it was obvious to see, feel and hear that they needed replacing. Noise so bad they sounded like they were open, a cold feeling inside the room and just looked like they needed replacing, windows sealed shut. Now with new installed. This front bay now looks amazing and our customer has already commented on the amazing difference in sound, appearance and thermal efficiency. Now also able to fully use every window, which also has a tilt in option to easily clean from the inside. Plus Shark finn restrictions when operated to stop the windows being opened further than a fists 👊🏽 distance. Ogee trims used and mitred to perfection to suit the character this property has. Happy home 🏡 happy customer 😊 happy us!
Thank you also to for the access as always 👌🏽

Another new conservatory build, converted from an old tired poly roof with old windows and doors to a new block, render and insulated cavities with a full plastered inside, new fully insulated fibreglass warm roof including a roof lantern, plus new thermally efficient windows and doors. Finished off with downlights inside and out. From a room that was loved but not usable through parts of the year to a room that's now able to be fully used all year round.
Wishing all my customers past and present a very merry Christmas. Thank you all for your business and believing in me. I really appreciate you all 🎅🏼🤶🏼🎄
