Home Renovation Merton

Full refurbishments and whole-house renovations in Merton. Trusted, professional, 30+ years' hands-on experience.

GS Renovation refurbishes whole houses across Merton, from tired Victorian villas in Wimbledon to Edwardian terraces around Mitcham Common and solid suburban homes near Morden. With more than 30 years of experience in SW19, SW20, CR4 and SM4, we take a dated property back to brick where needed and rebuild it as one coordinated project.

Whole-house refurbishment in Merton homes

A full Merton renovation usually means rewiring, replumbing and replastering throughout, because the services in a Victorian or Edwardian terrace are often decades past their best. We sequence the trades so first fix electrics and pipework go in before the walls are closed up, then plaster, second fix and decoration follow in the right order. One team holds the whole programme together.

Reconfiguring the dated layout is where these houses come alive. We open the cramped rear rooms into the closet wing, rework the awkward bathroom that was squeezed in over the years, and rethink how a narrow SW19 terrace flows from front door to garden, all while keeping the building sound and warm.

Restoring period features across the borough

Merton's bay-fronted terraces still hold cornicing, ceiling roses, picture rails, panelled doors and original fireplaces worth saving. Where these survive we protect and restore them, and where previous owners stripped them out we can reinstate mouldings that match the age of the house, so a refurbished Wimbledon or Morden home keeps its Victorian or Edwardian character.

Structural changes are woven into the same schedule. If the renovation includes a steel beam knock-through or a new opening, the engineer's design and building control sign-off are handled alongside the kitchen, bathrooms and decoration. That coordination avoids the stop-start delays that come from juggling separate contractors on an occupied Merton house.

FAQ

Frequently Asked Questions about Home Renovation Merton

How accurate is a home renovation quote for a Merton house?

Very, and deliberately so. Quoting home renovation low to win a Merton job and correcting it later is the commonest complaint homeowners have about builders, and it is not how GS Renovation operates. We survey the SW19 address, itemise, and stand behind the total. Anything genuinely unforeseen is costed and agreed before further work. Ring 07472 424 226 and ask GS Renovation for the SW19 breakdown before you compare it with another Merton quotation for home renovation. 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.

What should a written specification for a Merton renovation contain?

Enough detail that two contractors would price the same job. For your Merton property that means the extent of each trade, the materials and fittings by name where they are chosen, what is included in making good, and what has been excluded. Vague scopes produce quotations that cannot be compared and variations later. We price from a written scope and sets out what is not in it.

How are payments arranged on a Merton renovation?

In stages tied to work completed rather than to dates. On a Merton project each stage is defined in advance, and payment follows once that stage is finished and inspected. A large payment up front is a warning sign in any building contract. The arrangement is written down before work starts, alongside what happens if the scope changes during the job.

What happens at the end of a Merton renovation?

A joint inspection and a snagging list. Walking a completed Merton project with the owner produces a written list of everything needing attention, from a door that binds to paintwork that needs a further coat. Those items are worked through and signed off rather than left to correspondence. Certificates for electrical and gas work and any building control paperwork are handed over at the same time.

How is a Merton property protected while the work goes on?

By covering and separating before the first tool comes out. In your Merton house that means protecting floors and the stair on the access route, sealing off rooms not in the scope, covering fittings that are staying and securing the property at the end of each day. Dust travels much further than most owners expect. Protection costs very little and prevents most of what people complain about afterwards.

Does a Merton renovation need a party wall award?

Where the work affects a shared wall or excavates near a neighbour's foundation, notice is required and an award usually follows. That covers beams bearing into a party wall, chimney breast removal on a shared stack and foundations for an extension close to the boundary. The owner serves the notice rather than the contractor, and the timetable is started early because it cannot be compressed.
