7 Best Builders in Sunderland for 2026

Sunderland's housing stock is a mixed bag, and that's what makes finding the right builder here genuinely important. The city has streets of traditional Edwardian and Victorian terraces across Hendon, Pallion, and Millfield, alongside post-war semis in Farringdon and Hylton Castle, and newer builds spreading out towards Ryhope and Doxford Park. That variety means builders working locally need to be comfortable switching between lime mortar repairs on older brickwork and modern cavity wall construction in the same week. The ground conditions vary too, with some areas close to the River Wear sitting on heavier clay soils that affect foundations for extensions. Most enquiries from Sunderland homeowners fall into a handful of categories: single-storey rear extensions (typically priced from £18,000 to £30,000 depending on size and finish), loft conversions, garage conversions, and full house renovations on older terraced stock that needs damp-proofing as well as cosmetic work.

Every business on this page was drawn from third-party public business listings and ranked by public review rating and review count, with a small lift applied to businesses that show a working website and a contactable phone number. Before anything appears here, we check each business's homepage to confirm that builders work is what they primarily offer, which is how unrelated or miscategorised trades get filtered out. Any listing flagged as permanently closed is removed automatically, so you won't find dead-end contacts. Where you see a Trust Verified badge next to a business, that means it has additionally passed our full verification process, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information. You can see the complete list of checks on our How We Verify page. For any business on this page that doesn't carry that badge, those independent checks haven't been carried out by us, and you should do them yourself before committing to anything.

Before you call anyone, get at least three written quotes and make sure each one breaks down labour and materials separately so you're comparing like for like. Ask any builder you're considering whether they hold public liability insurance and ask to see the document, not just a verbal confirmation. For structural work, extensions over a certain size, or anything affecting drainage, you'll need Building Regulations approval, and a competent builder will expect that conversation and know whether your project also needs planning permission. If you're touching a party wall shared with neighbours, the Party Wall etc. Act 1996 applies, and written notice must be given in advance. It's worth asking upfront how variations to the agreed scope are handled in writing, because that's where costs tend to creep. A realistic payment schedule tied to project milestones protects you far better than a large upfront sum.
