Full refurbishments and whole-house renovations in Harrow. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refurbishes whole houses across Harrow, from tired 1930s semis in Pinner to substantial interwar homes near Stanmore Common. With over 30 years across HA1, HA2, HA3, HA5 and HA7, we manage rewiring, replumbing, replastering and structural changes as one sequenced project, run by a single accountable team.

Many of Harrow's interwar houses have never had a full refurbishment, and homeowners in HA5 and HA7 come to us with dated wiring, old plumbing and cracked lath plaster that all need addressing together. We strip back where needed, rewire to current standards, replace worn pipework, and replaster throughout, so the fabric of the house is brought up to date rather than patched around cosmetically.
Running everything under one team means the trades follow in the right order, first fix before plaster, plaster before second fix, and decoration last. That sequencing matters most in an occupied family home, where we keep dust down and rooms usable as far as possible. The result across a Harrow semi is a house that feels new inside while keeping the solid interwar shell that made it worth buying.
The compartmented layouts of 1930s Harrow houses rarely suit modern life, so a full renovation is the natural moment to reconfigure. We open up reception rooms with engineer-designed steel, relocate a downstairs cloakroom, rework the kitchen into the garden, and rethink how the first floor bedrooms and bathroom are arranged, all signed off by building control where the structure changes.
Where a Harrow home retains period detail, such as original cornicing, picture rails or stained glass around Harrow on the Hill, we restore and protect it rather than strip it out. Elsewhere we bring in clean contemporary finishes. Because kitchens, bathrooms, structural work and decoration are handled by the same team, the whole project stays coordinated on one programme and one point of contact.
Harrow homeowners choose GS Renovation because a full refurbishment involves many trades, and we run them all under one roof. Rewiring, plumbing, plastering, structural steel and finishes are sequenced by a single team, with clear pricing and tidy working in your interwar home. Over 30 years across HA1 to HA7 keeps the whole project accountable from strip-out to snagging.
George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.
Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.
Giorgio is an excellent and intelligent workman, and with very reasonable prices!… He paid a lot of attention to detail that is not common at all, and the final result was immaculate. Highly recommended!
FAQ
Every Harrow project is priced on its own merits, as the cost of home renovation varies with the size, specification and condition of the home. We give a clear, itemised quote up front with no obligation. Call 07472 424 226 for an estimate tailored to your property. 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.

Yes. A large share of Harrow's homes are 1930s and interwar properties, and we renovate them regularly. We plan each home renovation around their particular characteristics, such as cavity walls, regular original layouts and the generous plots that suit extending, so the result suits the building and meets building control.
Yes. Many Harrow interwar homes have cornicing, picture rails or coloured glass worth keeping, and we protect and restore these while rewiring, replumbing and replastering behind them. Internal renovation needs building regulations for the electrics and any structural change, not planning permission. We sequence structural work, kitchen, bathrooms and decoration together so the house is modernised without losing its character.
