Working in Harpenden
In Harpenden we cover AL5; we also cover St Albans, 4.7 miles away, and Luton.
Homes in and around Harpenden vary, so we look at the floor, the walls and the water system before we price anything. If your Harpenden water is hard, a tap with a removable aerator and a smooth one-piece basin top are easier to keep clean. Wall-hung vanities in Harpenden homes are fixed to suit what the wall is built from, which we check at the survey.
Supplies across most of Hertfordshire are very hard. Taps, plug wastes and toilet pans scale up quickly, so chrome copes better than matt black, and a removable aerator is worth having. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- 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
- A check that the wall can carry a wall-hung unit, with fixings to suit solid or stud walls
- Moving the waste and supply positions where the new unit needs them higher, lower or to one side
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.
Wall-hung or floor-standing
Wall-hung units leave the floor clear and are easy to clean under, but need a strong wall. Floor-standing units hold more and suit weak or uneven walls.
Rules that apply in England
In England, the tap and supply pipework come under the Water Supply (Water Fittings) Regulations 1999. A new waste connection to the soil stack can be Part H work, and adding a light to the unit or above it is notifiable under Part P.
