Full refurbishments and whole-house renovations in New Barnet. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refurbishes whole houses and flats across New Barnet, mostly Victorian terraces that have had a hundred years of piecemeal alteration and one bad 1980s modernisation. One team takes it back to sound fabric and rebuilds it in the right order, from the structure and the services through to plaster, joinery and decoration.

The order matters more than anything else in a full refurbishment. Structure first, then the roof and the rainwater goods, then first fix electrics and plumbing while the walls are open, then plaster, then second fix, kitchen, bathroom and decoration. Doing the pretty end early is how people finish a house twice. In a New Barnet terrace we usually start above head height, because a leaking valley gutter between two back additions has generally been the cause of the damp that everyone blamed on rising groundwater.
Damp in an EN4 terrace is rarely what the ad says it is. Nine times out of ten the ground outside has been raised above the internal floor by a patio or a path, the airbricks to the suspended floor are blocked or painted over, a cement render is trapping moisture in the brickwork, or the gutter is overflowing behind the downpipe. Fix those and the wall dries. We say that plainly rather than sell a chemical injection course, because a chemical course into a wall with an external ground problem does nothing at all.
A good number of New Barnet's Victorian and Edwardian houses were converted into flats, and refurbishing one is a different project from refurbishing a house. The lease sets what you may touch, the freeholder's licence to alter covers anything structural, and the managing agent will want method statements and the contractor's insurance before the first delivery. Most leases also restrict working hours, require a parking permit for the skip and forbid hard flooring over an occupied flat, which decides your floor finish long before you ever get to choose a colour.
Building control still applies either way. A whole house refurbishment in New Barnet typically triggers it several times over: any structural opening, the electrical work in kitchen and bathroom areas, a new or relocated boiler, insulation upgrades and any change to escape from the upper floors. We make a single application to Barnet Council or an approved inspector, book the inspections around the programme rather than after the fact, and hand over the completion certificate at the end along with the electrical certificates and the engineer's drawings.
A full refurbishment goes wrong at the joins between trades, so New Barnet owners use GS Renovation to hold the whole sequence under one contract. We appoint the engineer where structure is involved, run the trades in an order that does not undo itself, deal with the freeholder and managing agent on flats, and take Barnet building control through to certificate. Founder led, 30+ years hands on.

FAQ
A rough steer yes, a quotation no. Ring 07472 424 226 or email info@gsrenovationltd.co.uk and we will describe how home renovation normally runs in New Barnet, including the Barnet Council approvals involved. The figure itself waits until the EN4 property has been seen, because bay-fronted Victorian terraced construction rarely matches the assumption. That is what keeps a GS Renovation quotation accurate. Nothing at all is owed for the EN4 survey, and the written New Barnet 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.
Faster than most people assume, provided the survey is done early. The lead time on home renovation at an EN4 property is usually approvals and materials rather than labour, so GS Renovation starts both as soon as the New Barnet scope is signed off. Seasonal demand across Barnet does move it. Email info@gsrenovationltd.co.uk for the current position on bay-fronted Victorian terraced properties. The EN4 survey is free and there is no obligation afterwards in New Barnet.
Mostly because the process is clear from the first visit. You get an itemised quotation for home renovation, a written programme for the EN4 property, and one person to call throughout the New Barnet job. We are fully insured, company number 14611254, and GS Renovation handles the Barnet Council approvals rather than leaving them with you. Read the 31 MyBuilder reviews before deciding on a Barnet builder. Ask for EN4 addresses of finished Barnet work.
It can. Article 4 removes specific permitted development rights in defined areas, so changes that would be automatic elsewhere in New Barnet need a full application to Barnet Council. We check whether your EN4 address is covered before any design work starts.
Damp, decayed timber and load paths that are not where anyone expected. Solid-wall Victorian terraces with original chimney breasts and suspended timber floors hide all three, which is why home renovation at an EN4 address starts with careful opening up rather than demolition. GS Renovation tells a New Barnet homeowner immediately and prices the fix in writing. Nothing proceeds on a Barnet site until you have agreed it. Email info@gsrenovationltd.co.uk and we will explain how home renovation variations are agreed at an EN4 property.
Strip it where it has blown, overboard it where it is sound and you want the ceiling line kept. Tapping the ceiling tells you most of it: a hollow, drummy note means the plaster has lost its keys behind the laths and it will come down eventually, usually onto a new carpet. Stripping is filthy but lets you insulate and rewire properly. Overboarding with 12.5mm plasterboard and a skim is quicker and quieter, but it loses a little height and buries the problem if the laths are already going. Decide room by room.
Both, and the borough is not the limit. GS Renovation carries out home renovation throughout New Barnet and the EN4 area and across neighbouring areas, which is why the team is rarely far from an EN4 property. Free survey, written quotation, no obligation. Email info@gsrenovationltd.co.uk with the address for a visit. We will say plainly if a North London property is too far out. Aftercare and snagging afterwards are handled from the same EN4 team as the build.
