A whole-house renovation is a planned refurbishment of an entire home, typically combining rewiring, heating, plastering, new kitchen and bathroom, flooring and decoration, and sometimes layout changes, carried out in a logical order under one project.

If you have a whole-house renovation on your list for a property in Carmarthen, we can help from the first measurements to the final clean-up. For a typical home, plan for 8–24 weeks on site, depending on scope, though larger or more complex jobs take longer. We cover postcodes SA31 and nearby Llanelli, Ammanford and Gorseinon, and every quote we send is fixed for the scope described in it.

What are homes like around Carmarthen?

Dyfed covers Carmarthenshire, Ceredigion and Pembrokeshire. Stone cottages and farmhouses under slate roofs are common, often rendered or colour-washed, as in Tenby's brightly painted terraces. Llanelli has Victorian industrial terraces, Aberystwyth and Carmarthen have Georgian and Victorian centres, and bungalows and newer estates surround most towns.

Stone homes often need lime render, repointing and roof slating repairs. Terraces suit loft conversions and extensions, and rural bungalows commonly take extensions, porches and driveways.

Whatever era your Carmarthen home dates from, we plan a whole-house renovation around how it is actually built rather than a one-size-fits-all specification.

Planning and building rules in Carmarthen

Homes in Carmarthen come under the regulations for Wales, summarised below. We don't rely on general rules alone: we confirm the position for your address with the council before a quote goes out.

Internal improvements do not need planning permission in Wales unless the building is listed.

Building Regulations in Wales cover notifiable electrical work, drainage, ventilation and any structural change.

Rules change and every property is different, so we check the planning history and constraints for your address before we quote.

How does the job run?

  1. Survey and measure

    Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.

  2. Price and scope agreed

    After the survey we send a quote for a whole-house renovation that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.

  3. Dates and permissions

    Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for a whole-house renovation are in place before the first day on site.

  4. On site to finish

    On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.

Frequently asked questions

Do you cover Llanelli, Ammanford and Gorseinon?

Yes. As well as Carmarthen, we cover Llanelli, Ammanford and Gorseinon and the rest of Dyfed. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.

What contingency should I allow?

A contingency is money set aside for problems found once work starts, such as rotten joists, hidden damp or wiring that is worse than expected. For older houses, setting aside at least 10–15% of the build cost is sensible. We look for warning signs during the survey and price known issues upfront. If something unexpected is found, we explain it and price it before carrying on.

How much does it cost to renovate a whole house?

A full refurbishment of a typical 3-bed house costs £41,500–£110,000, covering rewiring, heating, plastering, a new kitchen and bathroom, flooring and decoration. A light refresh costs much less, while renovations with structural changes cost more. The biggest variables are the condition of the house and the kitchen and bathroom specification. We survey every room and give you a written price for the agreed scope.

Can you combine a whole-house renovation with other work?

Yes. Because we manage several trades under one contract, we can plan a whole-house renovation alongside other work on your Carmarthen home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.

What happens if you find damp or rot?

If we find damp or rot during a renovation, we stop that area, show you the problem and explain the likely cause, such as a leaking gutter, bridged damp-proof course or poor ventilation. We then give you a written price to fix the cause and repair the damage before carrying on. Treating the cause matters more than treating the symptom, so we focus on that first.
