Maidstone's housing stock is a real mix. You've got Victorian and Edwardian terraces in Fant and around the town centre, interwar semis sprawling through Bearsted and Loose, and plenty of post-war estates in Parkwood and Shepway. That variety means local builders genuinely do see it all: lime mortar repointing on older properties, cavity wall issues on 1960s builds, and loft conversions where the original roof pitch barely gives you the headroom you'd hope for. The local geology doesn't help either. Much of Maidstone sits on Kentish ragstone and greensand, which affects foundations and drainage. Builders who've worked the area know what to expect, and that experience matters when you're digging footings for an extension or underpinning a wall that's moved.

Every business on this page was drawn from third-party public business listings and ranked by review rating and review count, with a small lift given to those that show a working website and phone number. Before any business makes it onto the page, we check their homepage to confirm that builders work is what they primarily offer. That step keeps unrelated trades off the list. Any listing flagged as permanently closed is removed automatically. Where you see a Trust Verified badge on a business, that means they've gone further and passed our full independent verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information. You can see exactly what that involves on our How We Verify page. For any business that doesn't carry that badge, those checks haven't been done by us, and it's worth carrying them out yourself before you commit.

Before you hire any builder, get at least two or three written quotes. Prices vary considerably, and a quote that comes in much lower than the others isn't always a bargain. Ask for a full breakdown of labour and materials, a realistic start date, and a payment schedule tied to milestones rather than a large sum upfront. For structural work, check whether you need Building Regulations approval or a Party Wall Agreement with your neighbours. Your builder should know, but it's your responsibility to make sure the paperwork is in order. Ask to see their public liability insurance certificate before work starts, and if they're working with electrics or gas, confirm the relevant accreditations. References from recent local jobs are worth asking for too.

Frequently Asked Questions

How much does a builder cost in Maidstone?
Day rates for a skilled builder in Maidstone typically run between £200 and £350 per day, depending on experience and the type of work involved. For project-based pricing, a single-storey rear extension usually falls somewhere between £25,000 and £50,000 once you factor in foundations, blockwork, roofing, plastering, and first fix. Loft conversions tend to start around £30,000 for a basic Velux conversion and can reach £55,000 or more for a full dormer. Smaller jobs, like repointing, a new garden wall, or a garage conversion, will obviously cost far less. Getting two or three detailed written quotes is standard practice and gives you a realistic sense of the market rate for your specific job.
Do I need planning permission for an extension in Maidstone?
Many extensions fall under Permitted Development rights, which means you don't need a full planning application. But there are limits: single-storey rear extensions can extend up to 4 metres on a detached house or 3 metres on a semi or terraced property without permission, though larger extensions up to 8 metres or 6 metres require prior approval under the Neighbour Consultation Scheme. If your property is in a conservation area, such as parts of the town centre around All Saints' Church, or if it's a listed building, the rules tighten significantly. Building Regulations approval is separate from planning permission and applies to almost all structural work regardless. Maidstone Borough Council's planning portal is the right place to check your specific postcode before work starts.
What is a Party Wall Agreement and do I need one?
A Party Wall Agreement is a legal document required under the Party Wall etc. Act 1996. You need one if your building work affects a shared wall, boundary, or structure between your property and a neighbour's. That includes loft conversions where the wall is shared, rear extensions that involve excavating close to a neighbouring foundation, and any work on a wall that sits on the boundary line. You serve a Party Wall Notice on your neighbours at least two months before work starts. If they agree in writing, that's straightforward. If they don't respond or disagree, both parties need to appoint surveyors. Your builder won't handle this for you. It's your legal responsibility as the homeowner, though a good builder should flag it early.
How long does a typical extension or loft conversion take in Maidstone?
A single-storey rear extension on a standard Maidstone semi typically takes eight to fourteen weeks from groundworks to practical completion, assuming no major delays with materials or groundwork surprises. Full dormer loft conversions usually take six to ten weeks once the scaffolding is up. Those timelines assume Building Regulations approval is already in place before work starts, which is something to sort out well ahead of your planned start date. Lead times for builders in Kent have stretched in recent years, so don't be surprised if you're waiting four to eight weeks from agreement to a start date. Build that buffer into your plans, particularly if you're trying to coordinate with other trades like electricians or plumbers.
What should a builder's quote include?
A proper written quote should break down labour and materials separately, ideally line by line for each phase of the work. It should state what's included and, just as importantly, what's not. Watch out for quotes that lump everything into one figure with no breakdown; that makes it very hard to compare properly or challenge costs if something changes. The quote should also include a payment schedule. Staged payments tied to completed milestones are normal and fair. Avoid any builder who asks for more than a modest deposit upfront before work has started. VAT should be clearly stated. If the job involves skip hire, scaffolding, or Building Regulations fees, confirm whether those are in the quote or extra.
How do I check a builder is legitimate before hiring them in Maidstone?
Start by asking for their public liability insurance certificate and check the expiry date. A reputable builder will hand this over without hesitation. If structural work is involved, check whether they're affiliated with a recognised trade body such as the Federation of Master Builders, though membership alone doesn't guarantee quality. Ask for two or three references from recent jobs in the Maidstone area, and actually follow them up. Look at their reviews across public listings and pay attention to how recent they are and whether the builder responds to negative feedback professionally. Check Companies House to confirm the business is registered and active. For any gas or electrical work within the project, confirm Gas Safe registration or NICEIC/NAPIT membership separately. Don't rush the process. A builder worth hiring won't pressure you to sign quickly.
