Quality and craftsmanship on every job

Quality and craftsmanship are central to everything we do. We approach every project with attention to detail, making sure each element meets a high standard — from a bespoke kitchen installation to a full-scale renovation.

By combining expert skills, quality materials and thoughtful design, we deliver results that are durable, functional and well finished, completed on time and within the agreed budget.

For homeowners, builders and contractors

Our clients include private homeowners as well as other builders and contractors who bring us in to carry out part of their project, such as roofs or the shell of a building.

Even if your property is slightly further afield, we are happy to look at projects outside our core areas.

Planning ahead

What to sort out before work starts

Most building projects run more smoothly when a few questions are answered early. We go through them with you at the first visit, so the quote reflects the job as it will actually be built.

Planning permission or permitted development
Building regulations sign-off
Party wall notices for shared walls
Access, parking and skip space
Where materials will be stored
Which rooms stay in use

If drawings or structural calculations are needed, we tell you at the start rather than part-way through.

What our customers say

Built on recommendations.

Caws Carpentry have done an excellent job at opening up our wall and reinforcing it with steel. Ryan and his team were professional – on time, no problems.

GGary LangdownCustomer review

Caws Carpentry undertook a large extension with new roof, attic conversion and total refurbishment of the whole house over a period of 11 months. Caws Carpentry were well-organised with great attention to detail and kept us informed and consulted on changes to scope and cost. The quality of workmanship and finish was exceptional and we are so pleased with the result.

SSophie LiddellExtension, loft conversion & refurbishment

I thought this was a fairly straightforward job but as it progressed I realised there was more to it than I expected. In the end 3 different teams worked on it and I appreciated them each being experts in their own particular trade, rather than using someone who was more of a general carpenter/Builders. Each team was very efficient and did a superb job. Ryan was always available if needed and I was consulted on each stage of the project, and he took a lot of care to ensure the final design would stand the test of time. Highly recommend

They were efficient, friendly, and left the space looking better than we ever imagined. The new layout is perfect, and it’s made cooking and entertaining so much more enjoyable.

Our bathroom looks amazing after the renovation, thanks to the CAWS Carpentry team! They handled the bathroom installation smoothly from start to finish and paid attention to every little detail. They were punctual, courteous, and we couldn’t be happier with the final result.
