Working in Blackwood
We work right across Blackwood — NP12 — and in neighbouring Gelligaer and Risca.
Blackwood gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If you have bought a vanity unit for your Blackwood bathroom, fit-only installation covers connecting the tap and waste and testing for leaks. Wall-hung vanities in Blackwood homes are fixed to suit what the wall is built from, which we check at the survey.
Supplies across Gwent range from soft to hard depending on the source. Taps and wastes will need an occasional descale, and chrome or brushed finishes are easier to keep clean than polished brass. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Moving the waste and supply positions where the new unit needs them higher, lower or to one side
- Testing for leaks and checking the trap holds its seal
- Fitting the unit level, with the basin sealed to the top and the top sealed to the wall
- Patching or re-tiling the wall where the old basin left gaps
Decisions to make first
Width
Compact units around 400 mm wide suit cloakrooms; family bathrooms often take 600 to 800 mm for one basin and 1200 mm or more for two.
Waste and overflow
A basin with an overflow takes a slotted waste; one without needs an unslotted waste, often a push-button 'click-clack' type.
Rules that apply in Wales
Wales follows the same water fittings regulations as England. Its own Part P covers more electrical work, so a lit vanity or mirror should be connected by a registered electrician.
