Frequently Asked Questions — Window Installers in Renfrew

How do I check if a Renfrew window installer is FENSA registered?

FENSA is the main scheme for replacement windows in England & Wales. In Scotland, installers should be registered with CERTASS or similar, and work must comply with Scottish Building Standards. Ask for their registration number and verify it on the scheme's website.

What are window energy ratings and why do they matter?

Window Energy Ratings (WER) grade windows from A++ to E based on heat retention. For Scottish weather, aim for at least a B rating. A-rated or triple-glazed windows save more on heating bills. Scottish Building Standards set minimum U-value requirements for replacements.

Should I choose uPVC, aluminium, or timber windows for Scottish weather?

uPVC is the most popular and affordable — low maintenance, good insulation, handles Scottish rain well. Aluminium offers slim sightlines and modern looks but costs more. Timber is traditional, suits conservation areas, but needs regular maintenance. For most Scottish homes, uPVC offers the best balance.

Do Glasgow window installers cover Renfrew?

Renfrew sits between Glasgow and Paisley on the south bank of the Clyde. Tradesmen from both cities serve the PA4 area. The town has a mix of traditional sandstone tenements, post-war housing, and new-build developments.

How do I know if my Renfrew home needs replacement windows?

Signs include: draughts around frames when closed, condensation between panes (seal failure), difficulty opening or closing, visible rot or damage, cold spots near windows, and rising energy bills. Windows over 20 years old may benefit significantly from modern replacements.

How do I compare quotes from Renfrew window installers?

Get at least 3 written quotes and compare: window system and brand, energy rating, glass type (double or triple), frame material, old frame removal, disposal, building warrant fees, and guarantee length for both product and installation.
