Why Lian Construction
London building work goes wrong when trades aren't sequenced: finishes before repairs, decoration before leaks are resolved. We survey first, price a clear written scope, then coordinate roofing, plasterboard, tiling and decorating under one team — so you deal with one contractor from the first visit to the final snag.

Lian Construction is a London building contractor covering property refurbishment, kitchen renovation, bathroom renovation, loft conversion, property repairs, roof replacement, roof insulation, leak repairs, plasterboard repair, tiling, rendering and facade repair, brickwork and repointing, painting and decorating, partition walls, and landlord compliance works including HMO upgrades, fire doors and interlinked smoke alarms.
We work across all 32 London boroughs plus the City of London, with regular projects in Hackney, Camden, Lewisham, Southwark, Lambeth, Merton and Barking & Dagenham as well as South West London around our Kingston upon Thames base.
Send the property address, photos of the work if available and a short description through our contact page or by email. We survey the property, then provide a clear written scope and price before any work begins.
We work with several teams covering different parts of London, rather than one team travelling across the whole city for every job. A job is usually matched to whichever team is closest to the property, which keeps travel time and site costs down and helps us offer a competitive price without cutting corners on the work itself.
Yes. We handle HMO compliance works, fire risk assessment remedial actions, fire door installation, interlinked smoke alarms, end-of-tenancy redecoration and void refurbishments for landlords, letting agents and block managers across London.
Lian Construction holds a 5.0 average rating from 26 verified Google reviews. You can read them on our Google Business Profile or on the reviews page of this site.
Watch for a deposit over 25% of the total, no written quote with an itemised breakdown, a price well below other quotes for the same scope, no proof of insurance, and high-pressure tactics to book immediately. Our FAQ page and blog cover this in more depth, including a full guide to spotting the warning signs before you sign anything.
