House Refurbishment Hanwell

House refurbishment in Hanwell means renewing the whole fabric of a terrace, semi or detached house without re-planning it. The VOA count puts 36% of Hanwell homes before 1919 and 34% between the wars, and 42% of all homes here are terraced houses. That stock brings lath ceilings, lime-bedded brick, tired wiring and mixed pipework. We rewire, replumb, renew the heating, repair plaster, floors and joinery, and decorate, in one programme for the whole house.

For Hanwell, published UK figures put a three-bed house refurbishment at £43,530 to £110,350, and London houses usually cost more, with a London architect allowing £1,800 to £2,200 per square metre before VAT (Checkatrade and Bradley Van Der Straeten Architects, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Hanwell: we renew the wiring, pipework, heating, plaster, floors and joinery of the whole house under one contract, and a registered electrician certifies the rewire.

What a pre-1919 Hanwell house hides behind the plaster

Expect lime, lath and several decades of patching, and budget time for opening up before anyone fixes a price for the finish. With 36% of Hanwell homes built before 1919, houses such as the Edwardian terraces near the river come up often, and their walls breathe through lime mortar and soft plaster. Gypsum skim and cement render over that trap damp, so where we find sound lime work we repair it in lime rather than hacking it off.

Under the floors, look for iron gas pipe, lead or early copper water runs, and circuits that were extended rather than replaced. Those go early in the programme, while the boards are up, so the new wiring and pipework are fixed before the ceilings are repaired. A registered electrician tests and certifies the new installation, and any gas work is done by a Gas Safe engineer. Only then do plaster, joinery and decoration start.

Housing in Hanwell

Around 10,370 homes make up Hanwell on the valuation list; 42% are flats and 58% houses, and 36% date from before 1919, 34% from between the wars and 30% from after 1945. A rewire in a terrace in Hanwell chases cables into walls shared with neighbours on both sides, so the noisy days are planned and flagged, and 42% of homes here are terraced.

Interwar semis and terraces in Hanwell need different repairs

The 34% of Hanwell homes built between 1919 and 1939 are a separate job from the Edwardian stock. Walls are often cavity brick rather than solid, ceilings are more likely to be early plasterboard than lath, and original steel or timber casements may already have been swapped for later frames. The repairs that come up are tired roof coverings, failed flashings round the stacks, and floors notched too often by earlier trades, so we check the joists before any new boards go down.

Semis and detached houses make up 16% of Hanwell homes, and on those the side wall and a hipped roof add scaffold and gutter work that a mid-terrace does not have. A cavity wall also raises the insulation question once the plaster is off, and renewing a thermal element brings Part L into play. We agree with you which elements are being renewed, so the insulation that follows is planned into the order of works and not added at the end.

Windows, doors and roofs in Hanwell conservation areas

Check the conservation area before you order windows, a front door or a new roof covering. Ealing Council lists Churchfields, Cuckoo Estate, Hanwell Cemeteries, Hanwell Clock Tower and Hanwell Village Green among its Hanwell conservation areas, and says normal permitted development rights are restricted in them. Six conservation areas in the borough carry further Article 4 restrictions, so a like-for-like repair is the safe default and anything that changes the look of the front goes past the planners first.

At Churchfields, Half Acre Road, an Article 4 direction requires planning permission for enlarging a house by an addition or alteration to its roof. Repairing the existing slopes, stacks and gutters in matching materials is a different matter from altering the roof, so we keep the two apart in the scope. Rebuilding a stack shared with next door is work that needs a party wall notice, and the building owner serves that notice. Where a sash is sound we overhaul it with new cords, beads and draught-stripping; where it has rotted beyond repair, your designer confirms the replacement pattern first.

Skips, scaffold and working hours on a Hanwell street

Sort out the skip, the scaffold and the bays before the strip-out date, because Ealing licenses all three. An Ealing skip licence runs for 14 days and only an authorised skip company can apply, and the council does not allow a skip on the pavement. On a narrow Hanwell terrace street the choice is a skip in the road, one on your own frontage, a renewed licence for a longer job, or wait-and-load collections.

Scaffolding on the pavement needs a temporary structure licence, which the scaffold firm normally takes out, and hoarding usually has to leave 1.2 metres for pedestrians. A parking bay suspension needs 7 working days' notice, or 3 at a higher rate. Ealing keeps its SPG 10 Noise and vibration as interim guidance on building noise. We keep noisy stripping and chasing to normal weekday hours and tell the neighbours about the loudest days in advance.

• Smoke, heat and carbon monoxide alarms fitted to current rules on every storey
• Loft insulation topped up while the tank space is cleared
• Sash boxes overhauled with new cords, parting beads and brush seals

Trusted House Refurbishment in Hanwell

We run a house refurbishment as one programme from strip-out to decoration, so you are not coordinating separate trades through the walls of an old house. We visit first, open up where it matters, and give you a written quotation with the opening-up allowances shown. We plan the order of works around whether you are living in the house, book the bays and check the skip and scaffold licences, and bring in the registered electrician and Gas Safe engineer who certify their work.

• Radiators, sockets and switches positioned at first fix, never after decorating
• A written scope and programme agreed before work starts
• Every wall of the house tapped and every circuit tested before the refurbishment is priced
