Windows and doors in Caerphilly
Conservation and castle-setting views can limit designs near the walls — check before ordering. Event weekends slip installation dates.
Replacement windows and doors should be installed by a FENSA or CERTASS competent person so Building Regulations compliance is self-certified — otherwise notify Caerphilly CBC Building Control. Keep the certificate for sale of the property. Never pay the full balance before installation and snagging.
What to check
From Caerphilly station to the castle (walkable; taxis for evening return). FENSA or equivalent certification, U-values and lead times belong in the quote.
