Double Glazed Unit Replacement Across South London & Surrey

Misted, Cracked or Failed Glass? We’ll Replace the Unit Only

Not every glazing issue needs a full window replacement. If your double glazed unit has failed, JM Glass & Glazing can replace just the glass—no disruption to frames, no unnecessary cost. We operate throughout Croydon, Epsom, Banstead, and nearby areas.

What’s Gone Wrong?

Double glazed units often break down over time. Moisture can seep in, the seal can fail, or the glass can suffer visible damage. These issues reduce energy performance and visibility.


We Replace Units With:

  • Condensation or misting between panes
  • Visible chips, cracks, or scratches
  • Broken seals
  • Outdated or inefficient glass
  • Heat or sound loss through the unit

Our Focus is Speed and Simplicity

You don’t need to replace the whole window. We measure the faulty unit, supply a made-to-fit replacement, and install it neatly. Most units are replaced within 48–72 hours.


Suitable for Homes and Businesses

We work with homeowners, landlords, letting agents, and commercial premises. Whether it's a top-floor flat or a ground-floor office, our glaziers complete the job with minimal disruption.
