Working in Bangor
As well as Bangor itself (LL57 and LL59), we survey in Caernarfon, Llandudno and Colwyn Bay.
Bangor gets the same process as anywhere else: a free survey at your home and a written, itemised quote. Whether your Bangor bathroom needs a refresh or a full strip back to brick, the written quote shows both where both are realistic. If you have just bought a house in Bangor, renovating the bathroom before moving in saves living through the dust.
Most of Gwynedd is supplied with soft water. That leaves you free to choose matt black, brushed brass or clear glass without worrying much about limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Re-plastering or boarding, with cement-based boards and tanking in the wet areas
- New wiring, lighting, extractor fan and RCD protection, installed and certified by a qualified electrician
- Strip-out back to brick or studwork, with waste taken away by a licensed waste carrier
- Repairs to rotten floorboards, joists or other timber found once the room is open
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 Wales
Wales applies its own building regulations, including a wider Part P and its own Parts F and H. Structural and drainage changes go through building control in much the same way as in England.
