Services
uPVC Windows
Our uPVC window installations combine energy efficiency with modern aesthetics, featuring multi-chambered profiles for superior insulation. Backed by FENSA certification, these windows reduce noise pollution while enhancing property security. Available in various styles and colours to match your home's architectural character.
Composite Doors
Engineered for maximum security and thermal performance, our composite doors feature reinforced frames and high-density insulation cores. Supplied by Veka, they resist warping and fading while offering customisable designs including glass panels and decorative finishes to suit traditional or contemporary homes.
Conservatory Installations
We create bespoke conservatories using aluminium or uPVC frameworks with energy-efficient glazing systems. Our designs comply with current building regulations while maximising natural light. Options include tiled roofs for year-round usability and traditional orangery styles with decorative columns.
Tiled Conservatory Roofs
Upgrade your existing conservatory with our insulated tiled roofs, featuring lightweight composite panels and integrated ventilation. This solution transforms poorly insulated spaces into comfortable living areas while maintaining compliance with thermal efficiency standards.
Double Glazing
Our double-glazed units incorporate argon gas fills and low-E coatings to minimise heat loss. Installed with precision-engineered seals, they improve thermal retention by up to 70% compared to single-glazed windows while reducing external noise intrusion significantly.

Just had the front of my house replaced with J.P Windows on an old property I recently purchased, Over the moon with the final results. The Staff have been great from the first enquiry to the final fitting, Will definitely be recommending them to friends and family

We recently had new windows fitted by JP Windows and Conservatories and have had them in the past to fit a new front door etc. I cannot stress enough how pleased we are with the whole J P process, we previously had quite a bad experience with another local company and having JP do this new work was like a breath of fresh air !! The three fitters who came (Gareth, Kyle and Richie) were polite ,professional and very hard working, also nothing was too much trouble. They also left our home clean and tidy on completion of the task. We also had an existing problematic PVC window which had been installed
