Balham homes: what we plan for
- Victorian and Edwardian conversions — Many Balham houses have been split into two or more flats. Bathrooms are often squeezed into an old box room or the back addition, and the floor between the flats is usually timber, so sound and leak protection matter.
- Terraced houses around the Nightingale Triangle and the Commons — The period terraces between Balham and the Commons are often bought as houses ready for a new kitchen-diner and an updated family bathroom.
- 1930s and later purpose-built blocks — Blocks along the main roads come with managing agents, block rules and leases that often specify flooring and working hours.
Bathroom renovation in Balham
In an upper conversion flat, your bathroom is probably above your neighbour’s kitchen or bedroom. We take the room back, check the joists, tank the wet areas and pressure-test the pipework before anything is closed in. If you want to move the bathroom, we look at the soil-stack route first, because that usually decides what is realistic. See our London bathroom renovation page for what is included.
Kitchen renovation in Balham
A common Balham project is turning a narrow galley kitchen and a separate front room into one open-plan space. Our in-house team carries out the structural opening, plus the plumbing, electrics and plastering, so the kitchen fitter is not waiting for anyone. More on our London kitchen renovation service.
Full flat refurbishment in Balham
For a Balham flat you have just bought, a full refurbishment usually means rewiring, new heating, a kitchen and bathroom, plastering, new floors and decoration. We work in a set order and agree it in writing, so you know when the flat will be ready to move into. Read more about fixed-price flat refurbishment.
Upper and lower flats: living with your neighbours
In a conversion, the people below or above you will hear the work, and the shared floor is part of the job. We agree working hours that respect the building, protect shared hallways and stairs, take waste away as we go, and use an acoustic underlay where the lease calls for it. If your lease needs freeholder consent for the work, see our licence to alter guide.

Frequently asked questions
I have bought an upper flat in a Balham conversion. What should I check before renovating?
Read your lease for rules on alterations, flooring and working hours, and find out who the freeholder or managing agent is. At our survey we check the bathroom floor, the soil-stack route, the electrics and the heating, then give you a fixed price for the work.
How long does a full flat refurbishment in Balham take?
A typical one or two-bed flat takes 6–10 weeks depending on scope. A bathroom on its own takes 7–10 working days, and a kitchen fit takes 10–14 working days once the units are on site.
