Sunderland · Building & conversions

Builders in Sunderland

Phone numbers for builders covering Sunderland — extensions, loft conversions and refurbishment. Open a profile and call the business yourself. This site does not send your job.

Extensions and loft work need more than a day rate. The renovation budget tool can sit beside a local quote. A Newcastle card that says Tyne and Wear is not a reason to use this page. Houghton-le-Spring appears here when the firm is actually based there. Profiles show a name, the area they cover and a phone number. Public qualifications such as Gas Safe or NICEIC appear only when they are on the profile. Read the cost notes for a sourced national range; a figure on a card is not a quote.

Typical building & conversions costs

Checkatrade’s house-extension guide, per-square-metre table last updated March 2025, is a national sense-check for shell versus finished work. It is not a local tariff. An extension in Washington has side access and a trussed roof to cut. A terrace extension in Millfield has a lane and a party wall. Ask which drawing they priced.

A local rule to check in Sunderland

Many extensions, loft conversions and structural openings need building control, and some need planning. A listing is not an approval and not a party-wall agreement.

Questions before you phone

How do I find builders in Sunderland on this list?

Roker and the terraces toward Millfield are the older streets. Washington is a new town with drives and trussed roofs, often on the same trading card and almost never the same job. Names, service areas and phone numbers sit on the cards. Open a profile and call the firm yourself. A Newcastle card that says Tyne and Wear is not a reason to use this page. Houghton-le-Spring appears here when the firm is actually based there.

Does this page send my job to a Sunderland building & conversions firm?

No. You place the call. This site does not email or text anyone on your behalf.

What should the written price say for building & conversions in Sunderland?

Trusses and a drive, or a lane and a party wall.

What is easy to miss before booking in Sunderland?

Sea fret at Roker and a Washington cul-de-sac need different fixings and different parking. One city price erases that.
