Builder FAQs for Newport
How much does a builder cost in Newport?
Prices in Newport are usually around the middle of our UK guide ranges, or a little below. Your price depends on the job, access and materials, so compare a few quotes from builders in Newport.
Can I get a builder anywhere in Newport?
Yes. Builders work across Newport and the NP postcode area, including Caerleon, Malpas, Bettws, Rogerstone, Maindee and Duffryn. There are also pages for builders in nearby Cardiff, Bristol and Swansea.
Do I need planning permission for an extension?
Many single storey rear extensions fall under permitted development, but limits apply to size, height and location. Check with your local council before you start.
How long does a single storey extension take?
Typically 8 to 14 weeks on site once work starts, depending on size, weather and how quickly you choose finishes. Planning and design can add several months beforehand.
How many quotes should I get?
At least three. Make sure each builder is pricing the same drawings and specification, otherwise the quotes are not comparable.
Should I pay a builder a deposit?
A modest deposit for materials is normal on larger jobs. After that, pay in stages as work is completed and never pay for work that has not been done.
