Frequently Asked Questions
Do I need professional groundworks for a small project?
Yes. Even smaller works like single-storey extensions benefit from proper excavation, foundations, and drainage. It’s essential to comply with building regulations and protect your investment for the long term.
How long does site clearance usually take?
Site clearance depends on site size, waste type, and access. Most residential plots can be cleared within a few days, allowing construction to start promptly.
Are you insured and working to current standards?
Absolutely. KT5 Construction operates under full insurance cover and all relevant UK safety and quality standards for building an extension or larger construction projects.
