Hiring a builder in Walton-on-Thames means working with a very particular mix of properties. There are Edwardian and Victorian terraces around the station and Hersham Road, 1930s semis in Hersham and Burhill, and larger detached houses along the river towards Shepperton and Sunbury. Plenty of it sits on London clay, so foundations for extensions need proper thought, and tree roots are a regular headache. Flood risk near the Thames can affect everything from damp-proofing to how high your ground floor sits. Rear extensions, loft conversions, kitchen knock-throughs and full refurbishments are the bread and butter here, and many homeowners are stretching a three-bed house rather than moving.

The businesses on this page were drawn from third-party business listings and ranked by public review rating and review count, with a small lift for those showing a working website and phone number. We read each business's homepage to confirm that builders work is what they primarily offer, which keeps unrelated trades off the page. Listings flagged as permanently closed are removed automatically. Where you see a Trust Verified badge, that business has additionally passed our full verification covering trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information. Our How We Verify page has the full list. For anyone without that badge, we haven't independently verified them, so those checks are yours to do before you book.

Get at least two or three written quotes, and make sure they're itemised so you can compare like with like. Ask to see public liability insurance and check the cover amount and expiry. Ask who deals with Building Regulations sign-off, and whether the price includes the Building Control application fee, skip hire and scaffolding. For party wall matters, which come up often on terraces and semis, find out who serves the notices and who pays the surveyor. Agree a payment schedule tied to stages of work, not big sums upfront, and get it in writing along with a start date and expected duration. Ask for addresses of recent jobs nearby and, if possible, go and look at them.

Frequently Asked Questions

How much does a builder cost in Walton-on-Thames?
It depends on the job and the spec. A single-storey rear extension typically runs from around £2,000 to £3,000 per square metre, so a 20 square metre extension might land between £40,000 and £60,000 before kitchen fittings. A loft conversion with dormer usually costs £45,000 to £75,000. Smaller jobs like knocking through a wall with steel beam work often come in at £3,000 to £8,000. Day rates for general builders are around £180 to £250. Prices are higher near the river where access and site constraints add cost. Getting two or three quotes is normal, and a quote far below the rest is worth questioning.
Do I need planning permission for an extension in Walton-on-Thames?
Many single-storey rear extensions and loft conversions fall under permitted development, but not all. Flats, maisonettes and properties in conservation areas have tighter limits, and some homes have had permitted development rights removed. Check with Elmbridge Borough Council before you commit. Even where planning isn't needed, you'll almost certainly need Building Regulations approval. A good builder will tell you which route applies and won't start without the right sign-off.
Will I need a party wall agreement?
If you're building on or near a shared boundary, digging foundations within three metres of a neighbour's property, or cutting into a shared wall, the Party Wall etc. Act 1996 probably applies. That's common with terraces and semis in Walton and Hersham. You serve notice on your neighbours, and if they dissent, surveyors get involved. Budget roughly £700 to £1,500 per neighbour for surveyor fees. Ask your builder to make clear whether this is included in their quote or left to you.
How long does a typical building project take?
A kitchen knock-through might take one to two weeks. A rear extension usually takes 12 to 20 weeks from groundworks to plastering, longer if the weather turns or deliveries slip. Loft conversions generally take eight to twelve weeks. Don't forget lead-in time, as good local builders are often booked months ahead. Ask for a programme with stages and agree what happens if the schedule overruns.
Should I stay in my home during building work?
For smaller jobs, most people stay put. For a big extension that opens up the back of the house, or a kitchen you can't use for weeks, many families set up a temporary kitchen or move out for part of it. Dust, noise and loss of water or power for short periods are all part of it. Ask your builder how they'll protect floors, seal off work areas and tell you in advance about any shut-offs, including where your stopcock is and when it'll be needed.
How do I check a builder is reliable before hiring?
Start with the basics. Ask for proof of public liability insurance and check the dates. See whether they belong to a relevant trade accreditation and confirm it directly with the scheme. Look at online reviews and read the middling ones as well as the glowing ones. Ask for the addresses of two or three recent jobs and, ideally, speak to those customers. Check they have a proper company address and landline or mobile number that gets answered. Get a written contract, agree stage payments, and never pay a large deposit. A reasonable one is 10 per cent or less, with materials ordered on a schedule you've both agreed.
