Property Renovation Tip for Wandsworth Homeowners
Wandsworth properties near the river often have basements that are prone to damp. The high water table means external waterproofing alone isn't always sufficient, and we recommend a combined approach with internal tanking and a sump pump as backup. On the upper floors, many Wandsworth Victorians have been through loft and extension projects over the years that weren't properly documented. A structural survey before renovation starts is essential to understand what's been done and whether it was done correctly.
What a full property renovation covers in SW18
Three project patterns cover most of what we run in Wandsworth. The scope varies depending on whether you have a Victorian terrace, a riverside villa, or a combined renovation and extension.
Victorian terrace refurbishment on Wandsworth's period streets
The terraces along East Hill, Garratt Lane, and the streets running off Wandsworth Common have solid 9-inch brick walls, original lime plaster, and slate roofs. A full refurbishment covers rewire to BS 7671, full replumb including original lead supply and cast-iron soil stack, structural opening-up of the ground floor with a 152x89 UC steel beam, sash window restoration, lime plaster repairs, new kitchen and bathrooms, and complete decoration. Build time runs 14–22 weeks.
Riverside villa and combined renovation projects in Wandsworth
Properties on the streets between Wandsworth High Street and the Thames add basement waterproofing to the scope, given the higher groundwater close to the river. Build time 18–26 weeks. Where we combine renovation with a rear extension or loft conversion into a single coordinated contract, the programme runs 22–28 weeks, typically 4–8 weeks shorter than running them separately because the site is mobilised once.
Wandsworth-specific factors that affect renovation scope
Three Wandsworth conditions regularly change what a renovation involves. Each one is worth understanding before you commit to a specification.
Basement waterproofing near the Thames: what BS 8102 requires in Wandsworth
Properties within 200–300 metres of the Thames have persistently higher groundwater than those further inland. Where a renovation includes any basement work, tanking a cellar to habitable use, deep extension foundations, or underpinning, the specification under BS 8102 Grade 3 is typically: Newton 109-LM external membrane applied before backfill where excavation allows; Newton 508 cavity drain membrane internally as the primary barrier; and a sump pump with dual pumps and battery backup as failsafe. A ground investigation is essential before committing to below-ground work on riverside properties. For Flood Zone 2 or 3 properties under London Borough of Wandsworth, a Flood Risk Assessment is required as part of any extension planning application.
Undocumented structural work and conservation areas across SW18
Many SW18 Victorians have been through loft conversions, extensions, and internal alterations over the past 30–40 years that were never documented or signed off. A chartered structural engineer survey before the renovation identifies removed chimney breasts without proper support, undersized steels from past extensions, cut joists from pipe runs, and unauthorised loft conversions without Building Regulations sign-off. We commission this survey before pricing, so any remediation is built into the fixed-price contract before work starts. On conservation areas: Wandsworth Common, East Putney near Putney Bridge Road, and Magdalen Park in Earlsfield all require sympathetic design for exterior alterations. Wandsworth Council typically determines applications in 8–10 weeks. Internal renovations are unaffected.
How we manage a Wandsworth renovation from survey to handover
A full renovation in Wandsworth typically involves 14–18 different trades over 14–28 weeks. One project manager covers the job from survey through handover, with photo updates throughout.
Planning and Building Regulations for SW18 renovations
Internal renovations do not need planning permission under London Borough of Wandsworth. Building Regulations apply for the rewire (BS 7671 under Part P), structural opening-up (Part A), drainage (Part H), thermal performance (Part L), basement waterproofing (BS 8102 Grade 3 for habitable use), and any unvented cylinder (BS 7593 commissioning). For riverside properties needing below-ground work, ground investigation and Flood Risk Assessment are coordinated as part of the project. Fixed-price contracts cover labour, materials, all fees, structural engineer calculations, FENSA registration, party wall surveyor coordination, basement waterproofing, ground investigation, Flood Risk Assessment where applicable, conservation area applications where relevant, and Building Control fees. The contract is signed before any work starts. Variations are quoted in writing before they are done.

Frequently Asked Questions
- What does a Wandsworth property renovation involve?
- Three patterns cover most of what we run. A Victorian terrace full refurbishment covers rewire, replumb, structural opening-up, sash window restoration, lime plaster repairs, and new kitchen and bathrooms. A riverside Victorian villa renovation adds basement waterproofing to handle the higher groundwater close to the Thames. A combined renovation plus rear extension or loft conversion runs as a single coordinated project. Where the chartered structural engineer survey finds undocumented past alterations, the remediation is built into the scope. Every job runs on a fixed-price contract confirmed after a free site visit, signed before any work starts.
- How does basement waterproofing work on a Wandsworth riverside property?
- Belt-and-braces approach to BS 8102 Grade 3 (habitable use). Specification is typically external membrane where excavation allows (Newton 109-LM applied to the external face of the retaining wall before backfill), Newton 508 cavity drain membrane internally as the primary barrier, and a sump pump with dual pumps and battery backup as final failsafe. The cavity drain system collects any moisture that gets through the external membrane and channels it to the sump for pumping out. A ground investigation is essential before committing to below-ground work on riverside properties to confirm groundwater levels and soil conditions.
- Why do Wandsworth renovations often need a structural survey first?
- Because many SW18 Victorians have been through loft conversions, extensions, and internal alterations over the past 30-40 years that were never properly documented or signed off. A chartered structural engineer survey at the start of the renovation identifies undocumented alterations, typically removed chimney breasts without proper support, undersized steel beams from past kitchen extensions, cut floor joists from past pipe and cable runs, and unauthorised loft conversions that lack Building Regulations sign-off. We commission the structural survey before pricing the renovation rather than after, so any remediation is built into the fixed-price contract before any work starts.
