    “Luke is an exceptional installer and businessman. His communication in amazing and attention to detail is second to none. From the moment I contacted LDM installations he was there from start to finish. Even though he has a large business I never felt my repair was insignificant. The work was carried out at a mutually agreeable time and with little to no disruption. Even though my pug wanted to play with him constantly.”

UPVC windows: An overview

uPVC (unplasticised polyvinyl chloride) windows are durable, low-maintenance, and highly energy-efficient.

Installation involves:

  • Removing your old frames
  • Preparing the openings
  • Fitting new double- or triple-glazed units sealed to prevent drafts and moisture

They’re a popular choice for homeowners across the UK thanks to their insulation, security, and weather resistance.

  • Sash window: £500–£800
  • Tilt and turn windows: £500–£800

uPVC vs other window materials

Compared to timber or aluminium, uPVC offers the best value for money and requires minimal upkeep.

  • uPVC: Affordable, weatherproof, great insulation
  • Aluminium: Sleek design, more expensive, lower insulation
  • Timber: Natural appearance, high maintenance, costly

If you’re after low maintenance and energy efficiency, uPVC is the ideal all-rounder for modern homes.

How long do uPVC windows last?

uPVC windows typically last 20–35 years with proper maintenance.

High-quality installations can last even longer if cleaned regularly and checked for seal integrity.

Their long lifespan and resistance to rot, rust, and corrosion make them a worthwhile investment.

Maintaining your uPVC windows

Maintaining uPVC windows is simple, just follow these tips:

  • Clean frames and glass every few months using mild detergent
  • Check seals and hinges annually for wear
  • Lubricate locks and handles to keep them moving freely

These small steps will help extend your windows’ lifespan and maintain their energy efficiency.
