Property Renovation Contractors in Penge (SE20)
Professional property renovation contractors in Penge, South East London.
Why Choose All Well for Property Renovation in Penge?
Penge is one of the best areas in SE20 for renovation work. Victorian terraces regularly come up for sale in unrenovated condition with plenty of scope for a full refurbishment. We've done enough of these to know the common issues. Rewiring is almost always needed, the plumbing is usually a mix of lead, copper, and plastic from different decades, and the ground floor often needs damp treatment. None of it is complicated if you know what you're looking at.
Every project comes with a fixed-price contract, single project manager, and full certification including Building Control sign-off.

Property Renovation Tip for Penge Homeowners
Penge Victorians share the same construction as Anerley. Solid 9-inch brick walls, timber floors, and lime plaster. The lime plaster is important. Don't let anyone skim it with gypsum plaster, which traps moisture behind a hard shell and makes damp problems worse. Where the lime is sound, we leave it. Where it's blown, we repair with lime. It takes a bit more care than a gypsum skim, but the wall stays breathable and you don't end up with damp patches six months after your renovation.
What a full property renovation in SE20 typically covers
Three patterns cover most of what we run for full renovations in Penge. The scope varies by property type, but the bones are consistent across the Victorian and Edwardian stock in SE20.
Victorian terrace refurbishment on Maple Road and Penge Lane
The terraces along Penge High Street, Maple Road, Green Lane, and the streets running off Penge Lane regularly come to market unrenovated with room for a full refurbishment. Scope includes a complete rewire to BS 7671, full replumb including replacement of original lead supply pipes and cast-iron soil stack, structural opening-up of the ground floor with a steel beam (typically 152x89 UC for a standard 3.5-metre span), new kitchen and bathrooms, lime plaster repairs where the original is sound, damp treatment where required, and complete decoration. Build time 14 to 20 weeks with one team and a single project manager.
Combined renovation and rear extension in Penge: a single coordinated project
Where a buyer wants both modernisation and an open-plan kitchen-diner, which the original Victorian layout does not provide, we run the extension and renovation as one programme. Running them together cuts 4 to 8 weeks off the total programme and keeps a single team on site throughout. Edwardian cottages around Penge West station are tighter on plot but typically have a side return or small back addition that converts into useful ground-floor space during the renovation. Build time for a combined project is 18 to 24 weeks.
Penge property renovation: the site conditions that affect your scope
Three SE20-specific factors regularly affect renovation scope. They come up on almost every unrenovated property in the area, so it is worth knowing about them at the survey stage rather than discovering them mid-build.
Rising damp on the streets near Penge East and Penge West stations
Penge sits at the bottom of the Crystal Palace ridge. The streets near both stations have higher persistent groundwater and the original 1870s slate damp-proof courses have failed at scale. The tide mark of rising damp at about a metre above floor level is visible on most unrenovated ground-floor walls. Treatment is chemical DPC injection (silicone-based cream into the mortar course) plus salt-resistant replastering, or, where damp is severe, Newton 503 cavity drain membrane to BS 8102 with a sump pump. The work goes in early in the programme so new plaster has 4 to 6 weeks to dry before decoration.
Lime plaster, mixed-era plumbing, and pre-1980 electrics in SE20
Penge Victorians are built on solid 9-inch brick walls with original lime plaster. We repair with natural hydraulic lime (NHL 2 or 3.5 to BS EN 459-1) rather than gypsum. The wall stays breathable and damp patches do not reappear after handover. Most unrenovated SE20 properties also carry a patchwork of plumbing: original lead on the supply, cast-iron stack on the rear elevation, copper from the 1960s, and push-fit plastic from later patches. Thames Water replaces the public-side lead free of charge if the internal section is replaced at the same time. Cast-iron stack replacement with PVC covers the rear section. Pre-1980 properties typically need a full rewire to BS 7671 with new consumer unit, RCBO protection, and an Electrical Installation Certificate, notified under Part P to Bromley Building Control.
How Bromley Building Control and Thames Water apply to a Penge renovation
Penge falls under the London Borough of Bromley. There is no conservation area covering Penge itself, so internal renovations are unaffected by conservation review. That said, Building Regulations still apply across several categories, and some rear plots trigger a Thames Water requirement.
Building Regulations, party walls, and Thames Water Build Over in SE20
Building Regulations apply for the rewire (BS 7671 under Part P), structural opening-up (Part A), drainage (Part H), thermal performance (Part L: U-value 0.18 W/m²K for new walls and roof), and any unvented cylinder (BS 7593 commissioning by our G3 certified installer). Bromley Building Control charges a fee for a renovation inspection process. Many Penge terraces sit over public sewers running along the rear gardens, particularly on the older streets near Penge High Street. Where a rear extension projects over a public sewer, a Thames Water Build Over Agreement is required (council fee plus CCTV survey). For internal-only renovations, the Build Over Agreement is not triggered. We assign one project manager from survey through handover. They run the weekly programme, schedule the 12 to 16 trades involved across a full renovation, manage materials deliveries, and report progress with photo updates throughout the build. Fixed-price contracts cover labour, materials, all fees, structural engineer calculations, FENSA registration, party wall surveyor coordination (Agreed Surveyor route on a single fee where neighbours dissent), damp treatment where included, and Building Control fees. The fixed price is confirmed after a free site visit and the contract is signed before any work starts. Our office on Limes Avenue is 5 minutes from any Penge property.

Frequently Asked Questions
- What does a Penge property renovation involve?
- A full Victorian terrace renovation in Penge covers a complete rewire to BS 7671, full replumb including replacement of original lead supply and cast-iron soil stack, structural opening-up of the ground floor with a steel beam, new kitchen and bathrooms, lime plaster repairs, damp treatment where the survey finds it, and complete decoration. An Edwardian cottage follows the same scope on a tighter plot. Where a buyer wants an open-plan kitchen-diner, we run the renovation and rear extension as one coordinated project. The fixed price is confirmed after a free site visit and the contract is signed before any work starts.
- How do I deal with rising damp on a Penge ground floor?
- Diagnose first, treat second. Most damp on Penge ground floors is genuine rising damp from a failed slate DPC dating to the 1870s, made worse by the higher groundwater near Penge East and Penge West stations. The tide mark at about a metre above floor level confirms it. Standard treatment is chemical DPC injection (silicone-based cream into the mortar course) plus salt-resistant replastering with at least 1 metre of new plaster above the new DPC. Where the damp is severe or persistent, we use Newton 503 cavity drain membrane with a sump pump to BS 8102. The treatment goes in early so plaster has 4 to 6 weeks to dry before decoration.
- Do I need Bromley Council consent for a Penge renovation?
- No planning permission for internal renovations. Building Regulations apply for the rewire (BS 7671 under Part P), structural opening-up (Part A calculations from a chartered structural engineer), drainage (Part H), thermal performance (Part L: U-value 0.18 W/m²K for new walls and roof), and any unvented cylinder (BS 7593 commissioning). Penge has no conservation area restrictions so internal work is unaffected. Where a rear extension is part of the project and the extension passes over a public sewer (common on the older streets near Penge High Street), a Thames Water Build Over Agreement is required, with a council fee plus CCTV survey. Bromley Building Control charges a fee for the inspection process.
