We use A rated window profiles as standard so you will notice the difference even if we are replacing existing double glazing.

Snap Proof Locks as Standard

Our composite doors come fitted with the Ultion lock. 11 pins instead of the standard 5, accredited with the highest BSI 3 star rating, it comes complete with a £1000 guarantee against snapping. Watch this short video here.

Flush fitting casement windows

Premium Windows

The Residence 9 window system is designed to replicate the timber windows of the 19th Century while merging traditional aesthetics with modern materials to create a window that is both elegant, energy efficient and maintenance free.

Flush fitting sashes together with mechanical joints to give the appearance of a traditional Mortice and Tenon joint make these ‘A’ rated uPVC windows practically indistinguishable from a period timber window.

The authentic design will appeal to any homeowner requiring a top end luxury window.

Premium Sash Windows

When only the best will do we can now offer clients a uPVC sliding sash window that look just like traditional timber made windows.

Mechanically jointed to look just like tenon joints, integral horns and deep bottom rails make these premium windows practically indistinguishable from a traditionally made window. Around half the price of timber and of course, they will never need painting.

What our customers say

“I have just been up to the house and the windows look fantastic. Thank you for working so tidily and efficiently too!”
Nadine - Port St Mary

“From start to finish we couldn’t have been happier. It took just 9 days for the windows to be made and 3 days later the job was finished. The windows look great and the price was £4200 under the previous best price. Highly recommended.”
Tony - Douglas

“Thank you so much for our new windows and front door. They look fabulous and they’ve already made a huge difference to the house. Such quick and efficient work from quote to fitting and no dramas! Will be recommending you to family and friends.”
Sandra - Douglas

“We live relatively close to the Airport so there is a certain amount of noise but we have noticed it has diminished considerably with our new windows.”
Debbie - Castletown
