How our prices work

The “from” prices on these pages are guide prices for a typical job in this area, so you can tell early on whether a project fits your budget. They aren't quotes.

After a free visit we send a fixed written quote broken down by stage: groundworks, structure, roof, first fix, plastering, second fix and finishes. If you want to change something during the build, we price the change and agree it with you in writing before doing it.

We don't ask for a large deposit. You pay in stages as each part of the job is finished and signed off.
