House Renovation Wandsworth: Victorian Terrace and Period Property Specialists From £50,000
✓ Gas Safe Registered | ✓ NICEIC Approved | ✓ All Trades In House | ✓ Fixed Price | ✓ Free Site Visit | ✓ 26 Reviews – 5.0 Stars
A couple on East Hill called us in January. They had bought their Victorian terrace at auction in November: a stripped shell, no kitchen, no bathroom, rewired in the 1970s with a consumer unit that building control would not pass, original cast iron soil pipes, damp in the rear ground floor bay caused by a failed damp-proof course inserted in the 1980s rather than the original lime mortar repointing the wall actually needed, and a rear extension added in 1994 that had settled 18mm from the main structure, creating a cold bridge across the full width of the property.
Five problems. One property. One programme.
We assessed the full scope on a Thursday. Fixed-price quotation delivered the following Tuesday: £118,000 covering structural, damp, drainage, Gas Safe plumbing throughout, NICEIC full rewire, kitchen installation, two bathroom installations, decoration throughout, flooring, and snagging. Every trade in-house. One project manager. One point of contact.
The East Hill house was handed over fully renovated, Gas Safe certified, NICEIC certified, and building control approved in eighteen weeks.

House renovation in a Wandsworth Victorian terrace is not a sequential list of separate jobs. It is a single integrated programme where every trade decision affects every other trade: the plumber’s pipework routes determine where the electrician runs cables, the structural engineer’s beam positions determine where the kitchen units can sit, and the damp treatment determines the substrate specification for the plasterer and the decorator.
A house renovation company that subcontracts each trade separately loses control of this integration at every handover point. A house renovation company with all trades directly employed controls the programme from the first structural assessment to the decorator’s final coat.
Wandsworth’s Victorian terraces run from the late-Victorian properties north of East Hill built in gault brick with Gothic Revival detailing to the grand Toast Rack townhouses near the Common and the workers’ cottages and merchant villas of the old town. Every one of these property types presents the same five renovation challenges that a Wandsworth specialist encounters every week.
Structural - Chimney breast, RSJ, and load-bearing walls
The ground-floor layout of a Wandsworth Victorian terrace two reception rooms separated by a load-bearing wall, a narrow galley kitchen behind, and a chimney breast projecting into every room on every floor was designed for Victorian domestic life. Modern open-plan living requires structural intervention. Every load-bearing wall removal and chimney breast removal requires a structural engineer’s specification, an RSJ installed to that specification, building control approval, and Gas Safe disconnection where a gas fireplace is affected. All four are in-house.
Damp - The correct diagnosis before the correct treatment
Damp in Wandsworth Victorian terraces is consistently misdiagnosed. The most common error is installing a chemical damp proof course in a solid lime mortar wall. The chemical DPC cannot bond correctly to lime mortar; the treatment fails, and the damp returns within three years. The correct treatment for rising damp in an original lime mortar Victorian terrace is lime repointing to the correct specification, not a chemical injection. We confirm the correct diagnosis and the correct treatment at the survey stage, not after the scaffolding has been erected.
Services - Gas Safe plumbing and NICEIC full rewire
A Victorian terrace built between 1880 and 1910 has original gas pipework, cast iron soil pipes, lead supply pipes, and electrical wiring that has been modified multiple times across 140 years. A house renovation is the correct point to address all three simultaneously.
Separating the plumbing, drainage, and electrical programmes adds cost and programme time. Our Gas Safe and NICEIC engineers work simultaneously on first fix; one scaffolding erection, one floor opening, and one wall chase serve both trades.
Planning - Wandsworth's 46 conservation areas
The London Borough of Wandsworth has 46 conservation areas. The Wandsworth Town, Wandsworth Common, Magdalen Park, and Old Devonshire Road areas matter most in SW18. Internal renovation generally needs no planning permission, but an Article 4 Direction over the Magdalen Park Conservation Area (2023) removes some permitted development rights; external changes such as window replacement may need consent there. We confirm the planning and consent position at the free site visit before any design is committed.
Basement Renovation - The +189% opportunity
Basement renovation and basement conversion in Wandsworth Victorian terraces is the fastest-growing renovation category in the SW18 market. Many Wandsworth Victorian terraces have semi-basement rooms- lower-ground-floor spaces that are partially below pavement level, used as storage or utility rooms. Converting these to habitable living space bedroom, bathroom, study, or kitchen requires underpinning assessment, waterproofing, drainage, ventilation, and NICEIC electrical. From £45,000. Included in full house renovation programmes.

Basement renovation Wandsworth is growing at a rate that no other renovation category matches: up 189% in three months, up 136% year on year. The reason is straightforward: Wandsworth Victorian terraces are running out of upward extension space and outward extension space, and the value per square metre added by a basement renovation exceeds the value added by almost any other renovation category in SW18.
The Wandsworth Victorian terrace semi-basement, the lower ground floor room partially below pavement level, is in approximately 60% of period properties across the Tonsleys, the Toast Rack, and the streets between East Hill and Garratt Lane. These rooms are currently used as utility rooms, storage, or informal playrooms. They have restricted head height in some cases. They have no natural light in others. And they are structurally part of the main house, not a separate excavation project requiring underpinning and structural engineering at the scale of a full basement dig.
Converting a Wandsworth Victorian terrace semi-basement to a habitable room requires: waterproofing to BS 8102 cavity drain membrane or cementitious tanking depending on the specific conditions, drainage and sump installation, NICEIC electrical installation including emergency lighting, ventilation to Building Regulations requirements, plastering and decoration, and flooring appropriate for the below-ground environment. From £45,000 all-in. Building Regulations approval and completion certificate as standard.
For full basement excavation beneath the existing footprint, digging out, underpinning, tanking, all services, staircase, and habitable rooms from £85,000. This is the larger-scale basement conversion that adds a full floor to the property below ground level. Planning permission is required in some cases. Party wall notices are required in all cases. Our structural engineers, Gas Safe plumbers, and NICEIC electricians manage the full programme in-house.
Basement renovations Wandsworth from £45,000 for a semi-basement conversion. From £85,000 for full excavation. Free site visit and structural assessment. Fixed price within five working days. All prices exclude VAT. Call 020 7129 7418.
Victorian terraces SW18: The Tonsleys, Toast Rack, East Hill
The primary house renovation property type across SW18. Bay-fronted, three to four storeys, two or three reception rooms, galley kitchen, cast-iron soil pipes, lime plaster walls, original cornicing. The East Hill auction purchase: five problems, one programme, eighteen weeks is the defining Wandsworth Victorian terrace renovation project.
Edwardian semis: West Hill and Geraldine Road
Wider footprints than the Victorian terraces. Different loft geometry: hip roofs are less commonly converted than Victorian gabled roofs. Ground floor open-plan renovations are the primary opportunity alongside kitchen and bathroom upgrades. From £45,000 for the ground floor. From £90,000 full renovation.
Toast Rack Townhouses: Wandsworth Common
The grandest Victorian residential properties in SW18. Four and five-storey. Significant period features. Renovation programmes typically include basement conversion, ground-floor open-plan, full kitchen and multiple bathroom renovations, full rewire and replumbing, and loft conversion. From £180,000 for a complete programme. Listed building assessment where applicable.
1930s semis: Earlsfield and Southfields
Different construction from Victorian and Edwardian cavity walls, concrete ground floors in some cases, different loft geometry. Renovation typically focuses on kitchen extension, bathroom remodelling, full decoration, and NICEIC rewire. From £55,000 for a full renovation.
Riverside and Warehouse Conversions: Wandsworth Bridge Road
Open-plan layouts already. Renovation focused on specification upgrades: kitchen, bathroom, flooring, NICEIC electrical. From £40,000. No structural complications in most cases.
Auction and probate purchases
The East Hill project was an auction purchase. Pre-auction surveys are limited. Post-purchase, the full scope of renovation work often exceeds what the buyer expected. We carry out post-purchase surveys and deliver fixed-price programmes within five working days. The auction buyer who calls us on the day of completion has a fixed price in their hands by the following week.

Home renovation contractors in Wandsworth range from single-trade decorators and bathroom fitters to full-service renovation companies with all trades directly employed. The difference is not marketing; it is programme control and cost certainty.
When a Wandsworth Victorian terrace renovation is managed by a general contractor who subcontracts structural, plumbing, electrical, plastering, and decoration to five separate companies, five things can go wrong that are outside the general contractor’s control. The structural engineer’s beam delivery delays the plumber’s first fix. The plumber’s completion date slips and the electrician’s availability is no longer aligned. The plasterer starts before the electrician has completed second fix. The decorator finds a damp patch that the plasterer has skimmed over. Each one of these is a programme delay. Each one is a potential cost variation.
Chelsea Property Renovation & Maintenance Ltd employs every core trade directly: Gas Safe plumbers, NICEIC electricians, structural team, plasterers, decorators, tilers, and flooring specialists. One project manager controls the programme across all trades simultaneously. When the structural beam arrives on Tuesday, the Gas Safe first fix starts Wednesday. When the plumber completes on Friday, the electrician starts Monday. No subcontractor availability gaps. No handover disputes at trade junctions. One fixed price covering all trades from survey to snagging.
