Secondary Glazing Repairs – Restore Quiet, Comfort & Smooth Operation

What Secondary Glazing Repairs Involve

Secondary glazing is an internal glazing system installed alongside existing windows to improve
thermal efficiency, reduce external noise, and minimise draughts. While these systems are designed
to be durable, regular use and environmental changes can cause components to wear or fall out of
alignment over time.

Our secondary glazing repairs service focuses on identifying the cause of the
problem rather than masking symptoms. We inspect frames, runners, glazing panels, seals, and
locking mechanisms before carrying out precise adjustments or part replacements to restore
full functionality.

We repair all common types of secondary glazing, including horizontal and vertical
sliders, hinged panels, lift-out units, and fixed systems. Each repair is tailored to the specific
system to ensure smooth, quiet operation and a secure fit.

Common Secondary Glazing Problems We Fix

Secondary glazing faults often develop gradually and may go unnoticed until performance declines.
Early secondary glazing repairs help prevent further damage and restore comfort
quickly.

• Rattling or vibrating panels during windy conditions
• Sliding panels that stick, jam, or derail from the track
• Loose, broken, or misaligned handles and latches
• Misted, cracked, or damaged glazing panels
• Failed draught seals are causing heat loss and air movement

Resolving these issues improves usability, restores insulation, and prevents unnecessary strain
on frames and fittings.

Why Panels Rattle or Stick

Rattling and sticking are commonly caused by worn runners, distorted frames, or debris inside the
track. Seasonal temperature changes can also cause materials to expand or contract, worsening
alignment problems.

During repair, panels are removed, tracks cleaned, worn components replaced, and frames carefully
realigned so panels glide smoothly and sit securely when closed.

Repair Instead of Replace

In most cases, secondary glazing can be repaired rather than replaced. Repairs are quicker,
more cost-effective and far less disruptive, while preserving the original appearance of
your windows.

Secondary Glazing for Sash & Other Windows

We regularly carry out secondary glazing repairs on sash windows, particularly in
period properties where retaining original features is essential. Properly fitted
window secondary glazing improves comfort without altering the external appearance
of the building.

Repairs are completed with close attention to existing sash mechanisms, ensuring secondary glazing
does not interfere with sash cords, balances, or weights, and both systems operate smoothly
and independently.

We also repair secondary glazing fitted to casement, tilt-and-turn, and fixed windows, ensuring
consistent performance throughout the property.

Improving Comfort & Performance

Once repaired, secondary glazing should noticeably reduce draughts, minimise external noise,
and help maintain a more stable indoor temperature. Correct alignment and effective seals are
essential to achieving these benefits.

Our repair process ensures panels close evenly, seals compress correctly, and there are no gaps
that compromise insulation or acoustic performance.

Security & Ease of Use

Functional locks and catches are vital for both safety and convenience. As part of our
secondary glazing repairs, we ensure all locking points engage securely and
panels open and close effortlessly for everyday use.
