Building projects large and small
A general builder may take on anything from masonry repairs to a multi-trade renovation. Larger projects are easier to compare when every builder receives the same drawings, specification, structural information and statement of responsibilities.
Single- or two-storey extensions, side or rear additions, porches and other projects involving structural work and coordination with other trades.
Whole-room or whole-house improvement projects involving strip-out, repair, reconfiguration, making good and coordination between several trades.
New openings, wall alterations and structural supports where the work follows appropriate design, calculations and the required approval route.
New walls, repairs, repointing, steps, blockwork and other masonry where a general builder or brickwork specialist is appropriate.
Garage, loft-adjacent or internal reconfiguration projects that change how existing space is used, subject to design and permissions.
Local masonry, structural and building-fabric repairs, making good after other trades and work that goes beyond a typical handyman visit.

How it works
Describe the project once, share the information you already have and let builders who cover the postcode decide whether the scope fits their team and programme.
Enter the Hemel Hempstead postcode, describe the work, project stage, drawings or approvals you have and your preferred timing.
Your requirements can be matched through our partner network, and up to 3 local tradespeople can contact you about the project.
Compare relevant project experience, scope, exclusions, programme, communication and price before deciding who to hire.
Choose with confidence
For substantial work, compare more than the total price. Look at relevant experience, the clarity of the written scope, how the project will be managed and what happens when design or site conditions change.
Ask for recent examples and references from work similar in scale and complexity. Extensions, structural alterations and full renovations demand different planning from small repairs.
For larger work, agree the scope, insurance, programme, variation process and staged payments in writing. Avoid vague arrangements that make inclusions hard to judge.
Clarify who is responsible for drawings, structural design, planning matters, Building Regulations, inspections and completion paperwork before work begins.
