Building projects large and small
What can a Dartford builder help with?
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.
Renovations & refurbishments
Whole-room or whole-house improvement projects involving strip-out, repair, reconfiguration, making good and coordination between several trades.
Structural alterations
New openings, wall alterations and structural supports where the work follows appropriate design, calculations and the required approval route.
Brickwork & masonry
New walls, repairs, repointing, steps, blockwork and other masonry where a general builder or brickwork specialist is appropriate.
Conversions & reconfiguration
Garage, loft-adjacent or internal reconfiguration projects that change how existing space is used, subject to design and permissions.
General building repairs
Local masonry, structural and building-fabric repairs, making good after other trades and work that goes beyond a typical handyman visit.

Give every builder the same project information
Standardise the information before comparing totals so inclusions such as scaffolding, waste, steelwork and specialist trades are clear.
- Share drawings, dimensions, structural information and specifications you already have.
- State which permissions or approvals have been obtained and who is expected to manage inspections or paperwork.
- Explain access for deliveries, skips, scaffolding and materials.
- Ask each builder to state exclusions, VAT where applicable, payment stages, programme and how variations will be agreed.

Planning, regeneration and heritage are site-specific
Dartford Borough Council is continuing town-centre improvement work focused on public realm, transport, walking, cycling and regeneration. The adopted Dartford Plan to 2037 identifies Central Dartford, including the town centre, as a major development priority.
Clarify approvals before work starts. Planning permission, Building Regulations approval, structural calculations and party-wall matters are separate issues. Confirm which apply to the exact property and who is responsible for each before work begins.

What should you check before hiring a builder?
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.
Comparable project experience
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.
Contract, insurance & payment stages
For larger work, agree the scope, insurance, programme, variation process and staged payments in writing. Avoid vague arrangements that make inclusions hard to judge.
Approvals and responsibilities
Clarify who is responsible for drawings, structural design, planning matters, Building Regulations, inspections and completion paperwork before work begins.
