Plumstead is home. Every van starts and finishes here, and a huge share of Danny's original customer base, some now on the second or third boiler he has fitted, still lives inside SE18. The housing is mostly late Victorian terraces on the north side, larger Edwardian and inter-war homes climbing Plumstead Common, and post-war council stock in between. We know the pipe layouts by street, and often by house.

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 SE18 actually looks like.
Original small-bore pipework, ground-floor bathrooms added later, and boilers wedged into airing cupboards. We know the layout because we probably fitted the last one.
Larger footprints, often now on system boilers with cylinders. We size the replacement to the actual heat loss and radiator schedule, not to whatever was there before.
Combis fitted on tight budgets a decade ago are now ready for replacement. We give an honest repair-versus-replace call rather than defaulting to the sale.
Terraced Plumstead bathrooms are small. Getting a walk-in shower, WC and basin to actually work needs proper design, Danny will draw the layout with you first, not after ripping the room out.
SE18 extensions almost always break the heating circuit and move the boiler. We plan the pipe route with your builder before the slab goes down so the finished job actually works.
Speak to Danny or the office team direct on 07956 994429. Describe the problem or the project in Plumstead, we'll tell you what we need to see.
For anything bigger than a diagnostic, we survey the property and send a fixed, written quote. No sales pressure and no vague phone-guess pricing.
