Misted double glazing in Edinburgh & the Lothians

Check the paperwork for your windows before booking. Many sealed units come with a manufacturer guarantee against misting, and if your windows are still covered, the original installer or manufacturer may be responsible for replacing the failed unit under its terms.

Once the seal has failed, any argon or other insulating gas in the cavity has escaped and been replaced by ordinary damp air. The unit insulates less well than when it was new, and moisture inside can gradually leave deposits that dull the glass.

Common causes of seal failure include water sitting in the frame rebate because drainage holes are blocked, units fitted without correct packers, strong sun on dark frames, and age. Clearing the drainage slots in the frame helps protect the new unit from the same problem.

Replacing a misted unit is usually a short job per window once the new unit has been made. The old unit is lifted out, the frame rebate and drainage cleaned, and the new unit set on packers so the weight is supported and any opening sash stays square.

What applies in Edinburgh & the Lothians

Section 4 (Safety) of the Scottish Technical Handbooks covers glazing that people could collide with, such as glass in and beside doors and low-level glazing, where safety glass is needed.

Section 6 (Energy) of the Scottish Technical Handbooks sets the thermal performance that replacement windows, doors and rooflights should achieve.

Edinburgh & the Lothians has its own coastline, so for homes and businesses near the sea, salt air and wind-driven rain are part of the brief. Salt air and wind-driven rain put extra strain on sealed unit edges in coastal homes. Keeping frame drainage clear and gaskets in good order matters more, and the glazier checks both so the replacement unit is not sitting in trapped water.

In flats and terraced streets, replacing misted units often means planning access, parking and carrying units up stairs. Upper-floor windows may need to be done from inside, and conservation areas may require matching bars or glass patterns.

Misted Glass Repair in Edinburgh & the Lothians: questions

Is it worth replacing misted units or should I get new windows?

If the frames are sound, square and the hinges and locks work, replacing only the misted units is usually the more economical option. New windows make more sense if the frames are rotten, warped, draughty or hard to open. The glazier checks the frames at the survey and the quote will say if replacing units is not good value.

Can you clean the inside of a misted double glazing unit?

Not without breaking the seal. Some firms drill the glass, flush the cavity and fit a small vent, which can clear the mist for a while. It does not restore an airtight seal or gas fill, and white staining may not fully clear. Replacing the unit is the reliable way to restore a clear, sealed cavity.

How can I stop new sealed units misting early?

Keep the drainage slots at the bottom of the frame clear, so rainwater does not sit around the unit edges. Avoid pressure washing the seals, and do not paint over glazing gaskets. Check that opening sashes close properly, as a dropped sash can stress the unit. Report any cracked beads or failed gaskets early.

Can misted double glazing be fixed without replacing the window?

Yes. In most cases only the sealed unit needs replacing, not the frame. The glazier removes the beads, lifts out the misted unit and fits a new one made to the same thickness. Your frames, hinges, handles and locks stay as they are, provided they are in good condition, which the glazier checks at the survey.
