Frequently asked questions
Do you offer free quotes?
Yes. We visit your property, discuss your plans and then send a detailed written quote. There is no charge and no obligation.
Do I need planning permission for my project?
Many extensions and loft conversions fall under permitted development, but it depends on your property and plans. We will advise you at the first visit and can help with planning and building control applications where needed.
How long will my project take?
It depends on the scope. A bathroom typically takes one to two weeks, a kitchen two to three weeks and a single-storey extension around eight to twelve weeks. Your quote will include a realistic timeline.
Can I stay in my home while the work is done?
In most cases, yes. We plan the work to keep disruption to a minimum, protect the areas we are not working in and keep essential services running wherever possible.
How do payments work?
We agree a clear staged payment schedule linked to completed milestones before work begins, so you always know what you are paying for.
