Questions people ask

How do you check a builder before listing them?

We see their public liability insurance certificate and note when it runs out, and we check the owner's identity or Companies House record. Where the law or the job needs a registration, such as Gas Safe for gas work, we look it up on the official register. If a check runs out, they come off the list until it's renewed.

How much will home extensions cost in Preston?

Prices depend on the job, so ask for a written quote before work starts. We'll publish local price ranges once we have enough real quotes from the area to be useful.

How do you rank the trades you show?

Checked businesses come first, A to Z, with our green stamp. Other firms registered on Companies House as this trade locally are listed below them, also A to Z, without the stamp. Nobody can pay to appear higher.
