What Chiswick properties actually throw up
- Victorian and Edwardian terraces — Original sash windows, solid walls and floors that have moved over a century. Levelling and preparation is a real line in the quote here, not an afterthought.
- Bedford Park and the conservation streets — England’s first garden suburb sets a high bar on materials and detail. Getting mouldings, glazing bars and finishes right takes time, and we price that time honestly.
- Riverside and newer flats — Sounder fabric, but building management rules on working hours, lift use and waste removal drive the programme more than the work itself does.
Chiswick is unusually tightly controlled. Bedford Park and the surrounding conservation areas restrict what can change externally and to what standard, and Article 4 directions apply in parts of the area. This is a place where cheap materials are visible and often not permitted.

How we work
- Fixed price, agreed before we start. We survey the property, price the risks we can see, and hold that figure. We do not price low and find extras later.
- One team, one contact. Every trade is ours, so there is no gap between the plumber finishing and the tiler turning up, and nobody to blame if something is wrong.
- Two-year workmanship warranty on completed works.
- CDM Principal Contractor and Principal Designer qualified — the health and safety duty-holder role most small builders cannot take on, and a requirement on larger domestic projects.
- Over 100 completed projects across West London, including an eleven-flat commercial conversion.
Frequently asked questions
How much does a builder cost in Chiswick?
For defined works we quote a fixed price rather than a day rate. As a guide, a bathroom refit starts from £3,500 + VAT and a full one or two-bed flat refurbishment from £18,000 + VAT. Small repair visits are quoted individually.
Do you charge for a quote or a site visit?
No. The survey and the written fixed-price quote are free, and there is no obligation.
How long does a bathroom take in Chiswick?
Seven to ten working days for a standard three-piece refit. Layout changes, wet rooms and premium tiling run to two or three weeks, because the first-fix plumbing and tanking take longer.
Do I need planning permission to renovate in Chiswick?
Hounslow Council handles planning and Building Control in Chiswick. Large parts of W4 are conservation areas with restricted permitted development rights, and some streets carry Article 4 directions. Internal renovation normally needs no permission, but anything visible from the street usually does. We check before quoting.
Do you work for landlords and letting agents in Chiswick?
Yes — between-tenancy refreshes, full refurbishments and planned maintenance. Fixed prices and defined completion dates, which is usually what matters most when a property is standing empty.
Which areas near Chiswick do you cover?
Chiswick (W4), Acton, Ealing, Hammersmith, and the rest of West London.
