Double Storey Extensions in Maidenhead

What should I look for when hiring a builder for a double storey extension in Maidenhead?

When hiring a builder for a double storey extension in Maidenhead, look for clear scope, fixed-price quoting, proof of insurance, recent references, and a builder who can explain structure and Building Regulations without waffle.

The quote should include foundations sized for two floors, steels, floor structure, roof alterations, stairs or landing changes, and upstairs making good. For Maidenhead homeowners, the quote should separate structural shell, glazing, kitchen/finish allowance, and any drainage or flood-related checks.

The strongest hiring test is whether the builder can turn a vague idea into a clear scope before asking you to commit. Look for insurance evidence, references, quote detail, payment stages, Building Control knowledge, and a named person responsible for the site.

Double storey extensions add space upstairs and downstairs, so the structure, roof tie-in, drainage, and neighbour impact need more careful coordination. Planning risk is higher because height, overlooking, loss of light, and roof massing matter more than on most single storey work.

Maidenhead work often centres on family homes, open-plan layouts, riverside pockets, and higher expectations for finish quality. Many plots have decent access, but drainage, glazing size, and high-specification interiors can move the budget quickly.

Maidenhead sits under Royal Borough of Windsor & Maidenhead. The Royal Borough of Windsor & Maidenhead can require careful handling where previous extensions, flood considerations, or conservation edges apply.

Before agreeing the work, ask for a written scope that names inclusions, exclusions, payment stages, variation process, site protection, waste removal, and who manages the job day to day. That is the difference between a headline price and a buildable quote.

Planning permission and Building Regulations are separate. Even if planning is simple, Building Control still needs the relevant structure, insulation, drainage, fire safety, ventilation, electrics, roof work, and final completion evidence for the specific double storey extension.
