Working in Harpenden
We work right across Harpenden — AL5 — and in neighbouring St Albans and Luton.
In Harpenden, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. For listed and period properties in Harpenden, we check early whether listed building consent applies to the work you have in mind. A renovation survey in Harpenden looks behind the surfaces, at joists, pipework and wiring, before any figure is put on paper.
Water across much of Hertfordshire is very hard. We plan easy-clean glass, rimless toilets and finishes that do not show limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- New wiring, lighting, extractor fan and RCD protection, installed and certified by a qualified electrician
- A survey of the structure and services: joists, walls, ceilings, pipework, wastes, wiring and ventilation
- Strip-out back to brick or studwork, with waste taken away by a licensed waste carrier
- New hot and cold pipework and wastes, with isolation valves to each fitting
Decisions to make first
Heating
Moving the radiator, adding a heated towel rail or laying underfloor heating is simpler while the room is stripped.
Combining rooms
Taking out the wall between a bathroom and a separate WC gives one larger room, but it is structural work and may need building control.
Rules that apply in England
In England, structural changes, new drainage or a new connection to the soil stack under Part H, and new circuits under Part P can all be building regulations work. A registered electrician can self-certify the electrics; structural and drainage work may need a building notice or a full plans application to building control.
