Sidcup property patterns

The problems we see again and again in Sidcup.

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 DA14, DA15 actually looks like.

1930s semi heating layouts

The same story we see across our patch, small-bore pipework, undersized upstairs radiators, boilers picked on price. We resize honestly rather than copying whatever was there.

Unvented cylinders in larger homes

Bigger Sidcup family homes often run unvented cylinders. Legally notifiable and G3-only work, Danny is qualified, so it is done correctly with the paperwork.

Cold upstairs, hot down

Classic complaint in Sidcup semis. Almost always sludge and balance rather than boiler capacity. We diagnose properly and quote the actual fix, not a new boiler by default.

Bathroom refurbishments in family homes

Adding an en-suite or reworking a family bathroom is a common Sidcup job. Danny designs the layout with you so the pressure, capacity and drainage all actually work.

Landlord and letting-agent compliance

DA14/DA15 has a steady rental market. We batch CP12 inspections and annual services so portfolios stay compliant without last-minute rushes.
