Full refurbishments and whole-house renovations in Mitcham. Trusted, professional, 30+ years' hands-on experience.
GS Renovation carries out whole-house renovations across Mitcham, bringing tired 1930s semis and interwar terraces in CR4 up to modern standards under one roof. With over 30 years in the Merton area, we rewire, replumb, replaster and reconfigure dated layouts, sequencing every trade so your refurbishment runs as one coordinated project.

A 1930s Mitcham semi that has not been touched in decades usually needs the lot: old wiring replaced, plumbing renewed, walls replastered and a layout that suited 1930s living reworked for how families use a house today. We manage all of it in the right order, so first fix electrics and plumbing go in before plastering, and structural changes like opening up the reception rooms happen before the finishes. One team, one programme, one point of contact.
These interwar houses often keep worthwhile original features, picture rails, panelled doors, decorative plaster and cast fireplaces, and where you want them kept we restore rather than strip them out. Where a wall is load-bearing we bring in a structural engineer and the necessary steel, all signed off by Merton Council building control, so the character stays but the fabric, insulation and services are brought right up to date.
The value in a whole-house renovation is the sequencing, and that is exactly where a piecemeal, trade-by-trade approach falls down. On a Mitcham refurbishment we set out a clear order: strip out, structural work and steelwork first, then first fix services, plastering, second fix, and finally kitchens, bathrooms and decoration. Because one team holds the programme, the plasterer is not waiting on an electrician who has moved to another job.
Living in CR4 while the work happens is easier when the disruption is planned rather than open-ended. We phase the work so key rooms come back into use in a sensible order, keep the site tidy in an occupied home, and coordinate the kitchen and bathroom installs to land at the right point. The outcome is a house that has been renovated as a whole, not a collection of jobs that never quite line up.
Mitcham homeowners choose GS Renovation because a full renovation lives or dies on coordination, and we run every trade under one programme. Rewiring, plumbing, plastering, structural steel and the final finishes are all handled and sequenced by our own team, with building control sign-off where needed. Over 30 years in Merton means fewer surprises and a house that comes together properly.

FAQ
No, because everything foreseeable is on the quotation already. Home renovation in 1920s and 1930s suburban housing around CR4 occasionally reveals something behind plaster, and when it does we stop, cost it, and get your agreement before continuing at the Mitcham property. GS Renovation carries the same approach across Merton. Quotes are free and carry no obligation, whether the CR4 property sits in Mitcham or the wider South West London, and the written figure follows within days. As a rough guide, home renovation in London ranges from roughly £40,000 to £150,000 or more for a full refurbishment (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Long enough to do it properly, and the programme is agreed before we start. GS Renovation sets out the home renovation stages week by week for your CR4 property, from strip out through structure to making good. What moves the dates is inspection availability at Merton Council and what a 1920s and 1930s suburban house reveals once opened. Both are explained at the Mitcham survey, which costs nothing. Ring 07472 424 226 and we will map the home renovation stages against your CR4 property.
You get the scope in writing before anyone starts. The home renovation quotation for your Mitcham home lists structure, trades, approvals and making good, and the programme names the weeks and the Merton Council inspection points at CR4. GS Renovation appoints and coordinates the structural engineer where the design needs one. Aftercare is a phone call to the same number, not a form. Ask on 07472 424 226 about Merton aftercare. The five year guarantee on installations applies in Merton too.
Most internal renovations in Mitcham do not, though building regulations apply to structural, electrical and plumbing work. Extensions and external alterations may need permission or fall under permitted development. GS Renovation handles building control and any Merton Council applications for your CR4 project.
Most weeks, that is the whole of it. GS Renovation carries out home renovation on this stock across Mitcham and the wider Merton, so the CR4 property in front of us is rarely a new problem. Our founder brings over 30 years of hands-on experience to that judgement. Merton Council building control is coordinated as standard. Ring 07472 424 226 and we will describe how home renovation was recently handled on a very similar CR4 property.
Yes, that is exactly how we prefer to work. We take a Mitcham interwar semi from strip-out through rewiring, replumbing, replastering and any structural steel, then on to kitchen, bathroom and decoration, all sequenced by one team. Internal renovation does not need planning permission, though new electrics are notifiable under building regulations, which we handle as part of the job.
We do not think of it as travelling, because Mitcham is inside our normal working area. Home renovation projects run across Merton most weeks, so reaching a CR4 address is routine and there is no surcharge for it. GS Renovation also returns for aftercare, which matters more than the initial journey. Ring 07472 424 226 and we will confirm the position. The survey costs a Mitcham homeowner nothing. Snagging visits to CR4 are equally routine.
