Common jobs

Jobs homeowners in Isleworth often ask about

Single-storey extensions in Isleworth

A single-storey extension is a new ground-floor room built onto your house, usually at the rear or side, with its own foundations, walls and roof, creating a bigger kitchen, living space or bedroom without moving home.

Budget guide in Isleworth: £45,500–£98,000, with 10–16 weeks on site as a rule of thumb.

Double-storey extensions in Isleworth

A double-storey extension adds two floors of new space to your house in one build, typically a larger kitchen or living room downstairs with an extra bedroom, bathroom or en-suite above, sharing one set of foundations and one roof.

Typical time: 14–22 weeks on site. Local guide price: £78,000–£156,000 including VAT.

Garage conversions in Isleworth

A garage conversion turns an integral or attached garage into a warm, habitable room by insulating the floor, walls and ceiling, replacing the garage door with a wall and window, and adding heating, lighting and finishes.

Typical time: 2–6 weeks on site. Local guide price: £15,500–£36,500 including VAT.

Flooring in Isleworth

Flooring installation is the supply and fitting of a new floor finish, such as laminate, luxury vinyl tile, engineered wood or solid wood, over a properly levelled and prepared subfloor, with underlay, trims and thresholds finished neatly.

Expect 1–2 days per room, longer if levelling is needed for new flooring; the London guide is £1,550–£5,200.

Building work in Isleworth

London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.

London Clay shrinks and swells with the seasons, and street trees close to houses can contribute to movement, which affects foundation design.

Whatever era your Isleworth home dates from, we plan home improvements around how it is actually built rather than a one-size-fits-all specification.

Planning and building rules for Isleworth

For anyone in Isleworth, the relevant framework is England's. The summary below is general, so we always contact the council about your address before putting a price in writing.

In England, planning applications go to your local council, and many smaller extensions, loft conversions and outdoor jobs are permitted development. Conservation areas, listed buildings and Article 4 directions remove some of those rights. Building Regulations approval comes from council building control or a registered building control approver, or through a competent person scheme for certain trades.

Questions from homeowners in Isleworth

Do you cover Hounslow, Heston and Richmond?

Yes. As well as Isleworth, we cover Hounslow, Heston and Richmond and the rest of London. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.

Do I need planning permission in Isleworth?

It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Isleworth is in England, so England's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.

Which postcodes in Isleworth do you cover?

We cover TW1, TW3, TW4 and TW5, along with the rest of London. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.

What happens at the survey?

We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from your project, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.

Who do I deal with during the job?

One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.
