Why Erith customers keep calling us back.

Erith's housing is a genuine mix: Victorian and Edwardian terraces near the river, sizeable inter-war and post-war stock inland, plus the newer developments spreading out towards Slade Green and Northumberland Heath. That variety keeps the work interesting. The through-line is that Erith customers, like our SE18 customers, want a straight answer and a fair price rather than a script.

About 4 miles from our Plumstead base · approx 15 minutes on a normal traffic day.

Erith property patterns

The problems we see again and again in Erith.

Local heating and plumbing issues are rarely random. They follow the era of the property, the pipework, the water conditions and the way the house has been extended. Here is what our diary in DA8 actually looks like.

Riverside damp and cold external walls

Erith's riverside properties often have colder external walls and higher humidity than inland stock. Under-specified boilers and undersized radiators leave rooms that never quite warm up. We size correctly at survey.

Sludged systems in older semis

Inter-war and post-war Erith semis frequently have 20+ years of magnetite sludge in the radiators. Power flushing plus a magnetic filter usually restores full output at a fraction of the cost of a new boiler.

Ex-council maisonettes

Original combis in DA8 ex-council stock are typically past economical repair. We give a clear, numbers-based repair-versus-replace answer.

Slade Green-side newer estates

Newer estates use compact combis with tight utility-cupboard access. We plan flue runs and clearances carefully so a boiler swap does not need destructive work.

Landlord rental turnover

Erith has a busy rental market. We can turn CP12s around within a day or two, and batch annual services to keep a portfolio compliant without last-minute panic.
