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.
Whatever prompted you to look into a whole-house renovation, whether wear and tear, a growing family or plans to move, we can survey your Penarth home and give you a price in writing. Homes in Wales typically come in at £41,500–£110,000, VAT included, for this kind of work. We also cover Cardiff, Barry and Caerphilly, and the same steps apply wherever you are in South Glamorgan.

What are homes like around Penarth?
Cardiff has large areas of bay-fronted Victorian and Edwardian terraces in districts such as Roath, Canton and Cathays, plus interwar suburbs, post-war estates and modern flats around Cardiff Bay. Penarth has Victorian villas, Barry mixes terraces with newer estates, and Vale of Glamorgan villages are often built of local limestone.
Terraces commonly suit loft conversions, side-return and rear extensions, and bay window renewal. Suburban semis take side extensions and driveways, and stone village homes need lime-based repairs.
If your house in Penarth fits one of these patterns, it helps us anticipate what a whole-house renovation will involve, though we always confirm the details on site.

How does the job run?
We look at the job
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for a whole-house renovation, and photograph or measure anything the quote needs to reflect.
Written quote
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
Getting ready
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your Penarth property.
On site to finish
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.
What you can expect from us
Common questions
Which parts of a renovation need building regulations approval?
Several parts of a renovation fall under building regulations, including rewiring and new circuits, new boilers and heating systems, structural changes such as removing walls, replacement windows and changes to drainage. Some of this is self-certified by suitably registered trades, and some needs building control approval. In Scotland a building warrant may be needed for certain works. We arrange the right approvals and certificates.
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.
Can we live in the house while it is renovated?
Living in a house during a full renovation is possible but hard, especially while rewiring, plastering and the kitchen and bathroom are being done. Many people move out for the noisiest weeks or stay elsewhere for the whole project. If you stay, we can phase the work room by room and keep one bathroom and a basic kitchen working for as long as possible. We discuss this at the survey.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from a whole-house renovation, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
