Jason Humphries has spent 25+ years on the tools across King's Lynn and West Norfolk, from footings and drainage to full rear extensions and driveways.

Humphries Construction was founded by Jason Humphries in East Winch, Norfolk, on a simple idea: homeowners and small developers deserve a builder who quotes honestly, turns up when he says he will, and finishes the job to the same standard on day one as on day forty. **Who we help.** Norfolk homeowners planning single or two-storey extensions, families converting a garage into usable living space, landlords upgrading rental properties, and small developers needing reliable groundworks and foundations on new-build plots up to eight units. **What we specialise in.** Groundworks, foundations and footings, drainage, extensions, garage conversions, brickwork and driveways. We stay inside the disciplines we know cold rather than pretending to do everything. **Experience depth.** Over two and a half decades of Norfolk ground, Fen peat and silt around King's Lynn and Wisbech, Breckland sand around Swaffham, chalk around Hunstanton, and coastal clay near the wash. That local knowledge saves customers money on ground-condition surprises other builders discover mid-dig. **Where we work.** King's Lynn, Norwich, West Norfolk, Downham Market, Swaffham, Fakenham, Hunstanton, Wisbech and Dereham. If your postcode is inside a 40-minute drive of East Winch, we'll come out for a free survey within 7 days. Standards & philosophy ## How we run every job, from first call to handover. ### Fixed written price Every quote is itemised in writing within 3 working days. What you sign is what you pay, no mid-job surprises, no scope creep invoices. ### One point of contact Jason personally runs every project. No call centre, no rotating site managers. Same number, same voice, from quote to snag-list. ### Insured and warrantied £1,000,000 public liability cover, 10-year structural warranty on extensions, and a 2-year workmanship guarantee on garage conversions. ### Correct spec, first time We build to Building Regulations Part A, Part C and Part L as a baseline, not as an argument. Steel, footings and drainage go in to engineer's spec, always. ### Realistic timelines You get a written programme with survey, design, planning, build and snagging phases. If weather or supply delays hit, you hear about it the same day. ### Trusted long-term trades Jason brings in the same core team of subcontractors he's worked with for years, groundworkers, bricklayers, roofers. All fully trained and carrying their own insurance. No day-rate strangers walking off site when a cheaper job comes up. Our guarantees ## Written protection, not verbal promises. Every guarantee below is on your contract before we lift a spade. If it isn't in writing, it doesn't exist, that goes for us as much as for anyone else. ### 10-year structural warranty on extensions Covers foundations, walls, roof structure and load-bearing steels for a full decade from practical completion. ### 2-year workmanship guarantee on garage conversions If a finish fails through workmanship, not misuse, we return and put it right at no cost within 24 months. ### £1,000,000 public liability insurance Certificate provided on request before start on site. Protects your property, neighbouring property and any visitor to site. ### Fixed written price Your quote is itemised line-by-line. Variations are only ever raised in writing and signed off before work proceeds. Next step ## Speak to Jason directly. No middlemen, no waiting. Free site survey within 7 days. Written, itemised quote within 3 working days. Owner-managed from first call to final handover.
