House Refurbishment Bexley

House refurbishment in Bexley means renewing the services, plaster, joinery and finishes of a whole house without changing its plan. Houses make up 73% of homes here, and 41% of all homes date from 1919 to 1939. The job in front of us is often an interwar semi or terrace whose wiring, pipework and heating have reached the end of their life. We strip out, renew the services, replaster and hand the house back finished, whether you live in it through the work or it stands empty for a sale or a new let.

For Bexley, 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 Bexley: we renew the wiring, pipework, heating, plaster, floors and joinery of the whole house under one contract, and a registered electrician certifies the rewire.

Refurbishing the interwar semis and terraces of Bexley

The interwar house is the core of house refurbishment in Bexley. The VOA figures put 41% of homes in the borough between 1919 and 1939, and 40% of homes are semi-detached or detached, with another 27% terraced. A 1930s semi of that kind has timber floors on joists, a softwood stair and joinery, and wiring that later owners have extended one circuit at a time. A full refurbishment removes that patchwork rather than adding to it, and it is the moment to lift the boards and trace every pipe and cable back to its source.

Once the house is stripped, the order is fixed: first fix electrics and plumbing while the walls and floors are open, then plastering, then second fix, joinery and decoration. On a Bexley semi the heating is often the biggest decision, because a new boiler, new radiators and new pipe runs are far easier to lay while the floors are up. A registered electrician carries out and certifies the rewire, and a Gas Safe engineer handles the boiler. Panelled doors, skirtings and the stair balustrade can often be kept and repaired, which holds on to the period character.

Housing in Bexley

The Council Tax list puts Bexley at about 101,760 homes, 27% flats against 73% houses; 11% went up before 1919, 41% between the wars and 48% after 1945. Semi-detached houses make up 36% of homes here, and a semi in Bexley has a single party wall, so one neighbour hears the chasing.

Older Bexley houses and the conservation area controls

The 11% of Bexley homes built before 1919 need a gentler approach to the fabric. Lath and plaster ceilings, lime mortar and suspended timber ground floors should be repaired with materials that let the wall breathe, since cement render or a sealed membrane can push damp into the timbers. Sash windows are worth overhauling before anyone talks about replacing them: new cords, draught strips and sound timber spliced in where rot has taken hold. Damp and timber repairs follow a proper survey, so the treatment answers the cause rather than a guess at it.

Bexley has 23 conservation areas, and special controls apply to buildings in them, so check the council's maps before changing the windows, doors or front boundary of an older house. In the Red House Lane Conservation Area, an Article 4(2) Direction covers Nos 1-9 (odd) Red House Lane and No 44 Upton Road, and brings front porches and gates, fences or walls in front of a property within council control. At Old Forge Way in Sidcup, a similar direction reaches minor alterations, including enlargements or improvements to the exterior of a dwelling. Taking down a fence, wall or gate in a conservation area may need permission too.

Working hours, skips and scaffold on a Bexley street

A whole-house job in Bexley runs inside the borough's normal construction hours: 8am to 6pm on weekdays and 8am to 1pm on Saturday, with Sundays and bank holidays off. Stripping out, chasing walls for cables and breaking up old floor screed are the loudest stages, so we put them early in the week and early in the day. If a delivery or a pour really has to fall outside those hours, a Section 61 prior consent application is the route, and Bexley runs its 28 day response period from the day the application reaches its offices.

The strip out of a house fills skips quickly. A Bexley skip permit covers one skip for up to 14 days and has to be applied for at least two working days ahead, and where the house has no drive the skip may need a suspended parking bay as well. Roof, chimney-stack and gutter repairs usually need scaffold on the front, and where it stands on the pavement Bexley issues a scaffold or hoarding licence for a 3 month period. We line those dates up with the programme, so the scaffold is not standing idle and the skip arrives on the morning the strip out begins.

Building control, Part L and certificates for a Bexley house

Much of a house refurbishment is repair, which the Building Regulations leave alone, but some elements bring them in. Renewing a roof covering, replacing windows, fitting a new heating system or relining an external wall can trigger the Part L thermal standards, and a rewire is notifiable under Part P. A registered electrician notifies and certifies that through their own scheme, so it needs no separate building control application. In Bexley, building control must hear at least 48 hours before work starts on site. A building notice there carries no formal approval of the plans, while a full plans submission is checked and decided within five to eight weeks.

The close of the job produces the paperwork a buyer or lender asks for. In Bexley the notice of completion has to reach the local authority not more than five days after the work is finished, and the completion certificate that follows is what building societies, banks and solicitors rely on. For an executor preparing a probate sale, or a landlord re-letting the whole house, that certificate sits in the handover pack beside the electrical installation certificate, the gas safety paperwork and the window and boiler registrations. Keep the pack with the deeds.

Why Bexley Homeowners Choose GS Renovation

A house refurbishment brings many trades into one building, and the order they work in decides how long the house is out of use. We write the programme before we start: strip out, first fix, plaster, second fix, then joinery, decoration and floors. If you are living in the house, we phase it floor by floor and keep a bathroom and a basic kitchen working. If it is empty, the trades can overlap. You deal with one contact from the first visit to handover, and a written quote follows a site visit and a room by room scope.

• Paperwork and certificates handed over for when you sell
• A top-floor-first programme when your family stays in the house
• Radiators, sockets and switches positioned at first fix, never after decorating
