Good to know
Common questions
General guidance about builders in the UK, not specific to any one business.
Do I need planning permission for an extension?
Most single-storey extensions under certain sizes qualify for permitted development, but two-storey extensions and loft conversions usually need planning permission. Listed buildings have stricter rules. Local authority checks are essential.
What is building regulation approval and why does it matter?
Building regulations ensure construction meets safety, structural and energy standards. Most building work requires approval before starting. An inspector checks progress and issues a completion certificate, essential for insurance and resale.
How long does a typical extension take to build?
Single-storey extensions usually take 3 to 6 months depending on size and complexity. Two-storey extensions take 6 to 12 months. Timescales vary with weather, ground conditions and planning delays.
What happens if subsidence cracks appear during renovation?
Structural cracks need professional assessment. Causes range from settling to serious subsidence. Specialist reports may be needed before repairs. Insurance and legal advice should be sought for significant damage.
Can an old chimney be safely left in place during loft conversion?
Redundant chimneys can remain but need proper support and ventilation. They must not create weak points in new floor joists or reduced headroom. Professional assessment is needed for safe integration.
What prevents water ingress in new brickwork?
Proper mortar joints, damp-proof courses, cavity trays and adequate ventilation prevent water penetrating walls. Poor workmanship, incorrect mortar mix and missing details lead to persistent damp problems.
