Building in Caerphilly
The Rhondda, Cynon and Merthyr valleys are lined with stone terraces built for mining families, stepped along steep hillsides. Pontypridd, Caerphilly and Merthyr Tydfil have Victorian centres, and Bridgend has grown with large modern estates alongside interwar and post-war housing.
The valleys get heavy rainfall and steep, sloping sites are common, so drainage, retaining walls and render specification matter.
None of this holds for every street in Caerphilly, which is why we look at your actual house before pricing a whole-house renovation rather than assuming from its age alone.
Permissions for a whole-house renovation in Caerphilly
The notes below cover Wales, which is where Caerphilly sits. Rules change and every property is different, so we speak to the council before pricing your job.
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.
The four stages
We look at the job
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about a whole-house renovation.
Written quote
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Booking the work
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 Caerphilly property.
The work itself
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.
How we work
Whole-house renovations in Caerphilly: questions
Do I need planning permission in Caerphilly?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Caerphilly is in Wales, so Wales's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
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.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
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.
In what order should renovation work be done?
A renovation should follow a set order so finished work is never damaged by later trades. It usually runs from roof and structural repairs, through strip-out, first-fix electrics and plumbing, then plastering, second-fix electrics and plumbing, kitchen and bathroom fitting, flooring and finally decoration. Windows are usually fitted before plastering. We plan the programme around this sequence so each trade follows on smoothly.
