Foggy window replacement in Glasgow & Dunbartonshire

A new unit has to match the overall thickness of the old one so it sits in the existing rebate and takes the original beads. The glazier also notes any Georgian bars, leaded designs or obscure patterns so the replacement matches the other windows in the room.

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.

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.

Early seal failure often shows only on cold mornings or after rain and clears during the day. As the desiccant fills, the mist lasts longer and white mineral staining can form on the inner faces. Staining inside the unit cannot be removed by cleaning from either side.

What applies in Glasgow & Dunbartonshire

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.

Glasgow & Dunbartonshire 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 Glasgow & Dunbartonshire: questions

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.

Are misted units covered by a guarantee?

Often they are, for a period after installation. Many sealed unit manufacturers guarantee against misting, and the terms are set out in the paperwork from the original installer. If your units are still covered, contact that installer first. Units we supply carry manufacturer guarantees, and the terms are confirmed in writing with your quote.

How much does it cost to replace a misted sealed unit?

The cost depends on the size of the unit, the glass type, any Georgian bars, leaded or obscure features, how many units are done together, and access to the window. Larger units, safety glass and upper-floor windows cost more. See the guide prices for typical sizes, then get a written quote for your exact windows.

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.
