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.

FAQ
Not by much, and not because of the postcode. What raises a home renovation figure here is the housing rather than the location: 1920s and 1930s suburban houses with cavity walls and original hipped roofs take more making good than a modern estate. Access and parking around HA1 affect the labour line too. GS Renovation prices the property in front of it rather than applying a Harrow or North West London multiplier. Ring 07472 424 226 and GS Renovation will explain what actually moves the figure at HA1. 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.
Longer than the build alone, because approvals come first. A home renovation project at an HA1 address needs the engineer's design where the structure requires it, then a Harrow Council application, before the Harrow programme begins. GS Renovation runs those in parallel wherever possible. The survey costs nothing and is the quickest way to get real dates in Harrow. Ring 07472 424 226 and we will explain which Harrow Council route suits your HA1 property best.
Because you get one accountable team rather than a chain of subcontractors. GS Renovation is the contractor carrying out home renovation at your HA1 property, with a named project manager from survey to handover and full insurance throughout. We are rated 4.9 from 31 reviews on MyBuilder, and the Harrow Council paperwork is handled for you. That applies across Harrow and the wider Harrow. Ring 07472 424 226 and ask for HA1 references. Insurance details follow on info@gsrenovationltd.co.uk request.
Sometimes, depending on scope. Where the HA1 property is being rewired and replumbed throughout, most clients move out for the noisiest phase. We phase the Harrow works room by room where staying put matters to you, and say honestly when that is not practical.
Many times, and we can give you addresses. 1920s and 1930s suburban houses with cavity walls and original hipped roofs dominate that part of Harrow, so home renovation on them is routine work for GS Renovation rather than something we adapt to. The 31 public MyBuilder reviews behind our 4.9 rating cover the same kind of project. Ring 07472 424 226 and we will point you at recent work in Harrow. Email info@gsrenovationltd.co.uk and we will send HA1 addresses where home renovation of this kind was carried out.
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.
Our regular patch runs well past Hillingdon in every direction. Home renovation work takes GS Renovation across Harrow, the rest of Harrow and much of North West London in a normal month. An HA1 address is therefore easy to reach for the survey, the works and any snagging afterwards. There is no travel charge attached. Ring 07472 424 226 and we will confirm your street. Quotes are free and there is never any obligation to proceed.
