Most South Wales builders disappear the day the deposit clears. LEWZ runs on direct contact with the owner, fixed written quotes and tight on-site discipline — the way the trade used to work.

The Hard Way.
"Lewys and Craig did a brilliant job for us to the highest possible standard. Their work was faultless and was clearly just as it should have been. They were also very easy to have in the house - polite, considerate and professional. Thank you both."

"Insulation and boarding/plastering done so far by Lewys and Craig and they've done a fantastic job. Very accommodating, efficient work and excellent finish! House looks better than before and cleaner after they'd left! Thanks very much guys!"

Which areas do you cover?+
We're based in Pontypridd and work across South Wales — Cardiff, Caerphilly, Merthyr Tydfil, Bridgend, Newport — plus Bristol when the project's right.
Do you handle the whole build, or just parts?+
Both. We can take a project from foundations to final coat, or step in for a specific trade like bricklaying, render or plastering.
Are you fully insured?+
Yes — we hold £1m public liability and £10m employers' liability cover, and we're a registered limited company (Company No. 15585929). Evidence available on request.
How long does a quote take?+
We aim to send a fully itemised written quote typically within 48 hours of the site survey for most domestic projects.
Do you offer fixed prices?+
Mostly yes. We work on fixed written quotes for materials and labour on around 80% of jobs, with occasional day-work where it suits the project. We'll always agree the basis up front so there are no surprises at the end.
Can you help with planning and drawings?+
We don't draw plans in-house, but we can recommend architects and planners we've worked with.
