Double Glazed Window Repairs & Misted Double Glazing Replacement

The Problem

Double glazed windows can develop misting between the panes when the seal fails, letting in moisture. You might also have stiff hinges, broken handles, draughts or faulty locks. Replacing the whole window is often unnecessary and expensive.

Our Solution

We repair double glazed windows by replacing failed sealed units, fixing hinges and handles, sealing draughts and repairing locks. We only fix what needs fixing—no upsell. See our dedicated misted double glazing replacement and window repairs pages for more detail.

Our Process

• You call or request a quote; we arrange a convenient visit.
• We assess the window and give you a clear, free quote.
• We carry out the repair or sealed unit replacement at a time that suits you.
• You get a 5-year warranty on misted unit replacements where applicable.

Misted Double Glazing Replacement

When the seal between the two panes fails, moisture gets in and the unit mists. We replace the sealed unit with new low-E glass and warm edge spacer technology. Over 90% of failed units are south-facing due to temperature changes. We cover Rotherham, Sheffield, Doncaster and across South Yorkshire.

Hinges, Handles, Draughts & Locks

Stiff or broken hinges and handles, draughty seals and faulty locks are all part of our double glazed window repairs. We stock quality parts and don’t use the cheapest options—we use what lasts. For lock emergencies we offer a 24/7 line.

UPVC Repairs

We repair UPVC and aluminium double glazed windows. We don’t recommend full window replacement unless the frame is beyond repair. Thousands of parts are available, including for older systems—check our Trade Counter for spares.

Frequently Asked Questions

What are double glazed window repairs?

Double glazed window repairs cover fixing issues with your double glazed windows without replacing the whole window. This includes replacing misted or failed sealed units, repairing hinges, handles, locks, and fixing draughts. We repair only what is needed.

How much does misted double glazing replacement cost?

Cost depends on the size and number of units. We provide a free, no-obligation quote after a quick visit. Most single sealed unit replacements are affordable and much cheaper than replacing the whole window.

Do you replace misted units only, or the whole window?

We usually replace just the failed sealed unit (the glass sandwich), not the whole frame. This is faster, cheaper and keeps your existing window. We only recommend full replacement when the frame is beyond repair.

What areas do you cover for double glazing repairs?

We cover Rotherham, Sheffield, Doncaster, Barnsley and across South Yorkshire. We serve domestic and commercial customers within our service area. Call us to confirm we cover your postcode.

Is there a warranty on misted unit replacement?

Yes. We offer a 5-year warranty on our misted double glazing replacement for UPVC and aluminium units. New units use low-E glass and warm edge spacer technology for better energy efficiency.
