Wokingham's family houses, villages, and high commuter demand often lead to extensions, lofts, landscaping, and premium kitchen or bathroom upgrades.
Keep local quotes comparable by fixing the same scope, quality threshold, and access assumptions before you let providers price the job.
Ask every builder to price the same drawings, structural assumptions, and provisional sums.
Confirm whether scaffolding, waste removal, skips, and temporary protection are included or excluded.
Get stage payments tied to visible milestones instead of open-ended weekly billing.
Make sure building control, structural engineer sign-off, and making-good items are priced explicitly.
Local availability and logistics can make weak quotes look persuasive. Push these risks into writing before you approve the shortlist.
Large cash deposits before materials, drawings, or programme details are agreed.
Quotes that ignore structural unknowns but still promise a fixed total and start date.
Refusal to discuss insurance, references, or who is responsible for building control coordination.
Pressure to skip written scope, staged payments, or neighbour access planning.
Many single-storey rear extensions fall under permitted development rights. However, if your property is in a conservation area, is listed, or the extension exceeds size limits, you will need planning permission. Always check with your local planning authority before starting work.
Look for verified customer reviews, proof of public liability insurance, membership of trade bodies like the FMB or NHBC, and ask to see examples of completed projects. A reliable builder will provide a detailed written quotation and a realistic timeline.
Builders handle the above-ground structure — walls, roofs, and finishes. Groundworkers prepare the site, dig foundations, install drainage, and lay services. Many extension or new build projects require both.
A typical loft conversion takes 6–10 weeks depending on the type (Velux, dormer, or mansard). The structural work takes 2–3 weeks, followed by plastering, electrics, plumbing, and finishing.
Compare local context before requesting quotes.
