Triple Glazed Installation

Premium service installing windows with three panes of glass for maximum thermal efficiency. These units achieve U-values as low as 0.8 W/m²K, exceeding standard building regulations and significantly reducing heating costs. Argon gas fills the cavities between panes for enhanced insulation. Warm edge spacer bars prevent cold bridging. Particularly effective in properties with high energy bills or those seeking passive house standards. The additional glass weight requires robust hinges and stays, which we fit as standard. Service includes thermal imaging assessment showing heat loss reduction. Investment pays back through lower energy consumption over time, typically within eight to ten years.

Coloured Frame Installation

Installation of uPVC windows in non-white finishes including woodgrain effects, grey, black, cream, and custom RAL colours. Frames use through-colour or foiled profiles that resist fading and maintain appearance for decades. Woodgrain options replicate oak, rosewood, or mahogany textures, combining aesthetic appeal with plastic durability. Popular for period properties, conservation areas, or modern architectural designs. Internal and external colours can differ, allowing white interiors with coloured exteriors. Manufacturing requires additional time compared to standard white. Hardware finishes match frame colours. Service includes colour samples and consultation to ensure compatibility with property style. No repainting required throughout the product lifespan.

From £520

Per window | 30+ colour options

What Our Customers Say

Real feedback from homeowners across London and surrounding areas who chose our window installation services

James Mitchell

Birmingham

Had 6 windows replaced in my Victorian terraced house last month. The installers arrived exactly at 8 AM as promised, protected all floors and furniture with dust sheets, and completed everything in one day. The old frames came out cleanly without damaging the brickwork, which was my main concern. New UPVC units fit perfectly, no gaps or drafts. The house is noticeably warmer now and street noise has reduced significantly. Received all certificates and warranty documents the same evening. Very satisfied with the entire process from initial measurement to final cleanup.

Sarah Patterson

Manchester

Good quality windows at competitive price. Installation took slightly longer than estimated - they said 6 hours but finished after 8 hours. The team was professional and cleaned up properly afterwards. Would have appreciated more color options for handles and frames, but overall happy with what we got.

Robert Harrison

Leeds

The installation itself was fine and windows seem decent quality. However, there was some miscommunication about the delivery date - originally scheduled for Tuesday but arrived on Friday without prior notice. Price was fair for what we received. Customer service could respond faster to queries. The end result meets our expectations, though the process could have been smoother.

Emma Collins

Bristol

Brilliant service! My energy bills dropped by £45 per month after replacing single-glazed windows with their A-rated double glazing. The surveyor explained everything clearly during the quote visit and suggested the most cost-effective solution for our budget.
