Replacement uPVC windows for homes and businesses in Glasgow & Dunbartonshire

uPVC window frames are made from extruded profiles with several internal chambers that trap air and slow heat loss. Larger frames, and those on exposed elevations, are usually reinforced with steel or aluminium inside the profile so they stay straight and the locks keep engaging properly over the years.

uPVC no longer means white only. Frames can be foiled in woodgrain or solid colours such as grey, black or cream, often outside only with white inside. Foils are bonded at the factory and should be cleaned with a soft cloth and mild detergent, because abrasive pads and solvents mark the surface.

uPVC frames need washing a few times a year with warm soapy water and a drop of light oil on hinges and locking points. Drainage slots along the bottom of the outer frame let rainwater escape, so keep them clear of dirt and leaves to stop water collecting in the cill.

Windows are replaced room by room, so each opening is only exposed for a short spell. A single window is usually changed within a day, and a typical house takes a few days depending on the number of windows, bays and access. Inside, reveals are finished with trims, sealant or filler.

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. Near the coast, salt spray and wind-driven rain test seals, drainage and hardware. uPVC itself does not corrode, but stainless or coated locking parts, well-sealed joints around the frame and clear drainage slots matter, and exposed elevations may need frames with higher weather ratings.

In terraced streets and flats, old frames are usually removed and new ones fitted from inside to avoid scaffold. Parking for the van, access through communal areas, leaseholder consent and the lack of permitted development rights for flats all need checking before ordering.

Choosing your uPVC windows

uPVC sliding sash

Vertical sliders that mimic traditional box sashes, using spring balances instead of weights, where planning rules allow uPVC.

Georgian or astragal bars

Bars set between the panes or applied to the faces of the glass for a traditional divided-pane look.

Obscure and acoustic glass

Patterned or satin glass for bathrooms and street-facing rooms, and laminated acoustic glass to reduce traffic noise.

Casement windows

Side-hung or top-hung sashes on friction hinges, suiting most houses, with easy-clean hinges that let upper-floor glass be cleaned from inside.

uPVC Windows in Glasgow & Dunbartonshire: questions

Will fitting new windows damage my plaster or decor?

Some disturbance is normal, but it is usually limited to the edges of each opening. The glazier cuts out the old frame, fits the new one and finishes the inside with trims, sealant or filler. Older frames set deep into plaster may need some plaster repair, and we flag that at survey so it is covered in the quote.

Should I choose double or triple glazing?

Well-specified double glazing with low-E glass and warm-edge spacers can meet the energy standard for replacement windows, and the certified rating confirms it. Triple glazing adds a third pane, which helps on cold, noisy or north-facing elevations, but the units are heavier and need frames designed for them. We can quote both so you can compare.

How long does it take to fit uPVC windows?

Most single windows are changed within a day, and a typical house usually takes a few days. Bays, large picture windows and openings that need a tower or scaffold take longer. Manufacturing comes first, because every frame is made to the survey measurements, and the lead time is confirmed with your quote.

How much do uPVC windows cost?

The cost of uPVC windows depends on the size and number of windows, how many sashes open, the frame colour, the glass and the access. White casements with standard double glazing sit at the lower end, while foiled colours, triple glazing and bay windows cost more. See the guide prices for typical ranges; the written quote fixes the price for your specification.
