Working in Lisburn
We work right across Lisburn — BT17, BT26, BT27 and 1 more postcode districts — and in neighbouring Belfast and Castlereagh.
Lisburn is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. Where your Lisburn home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go. We survey cloakrooms in Lisburn with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly.
Supplies across most of County Antrim are soft. In soft water, taps, wastes and toilet pans scale up slowly, so brushed and matt finishes are a safe choice. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Splashback or feature tiling and a new floor, often LVT or porcelain
- A concealed cistern frame or WC unit where the space allows
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
- A new waste connection to the soil stack or drain, or a macerator where the rules allow it
Decisions to make first
Under-stair layout
Headroom drops quickly under stairs. The basin and the space in front of the WC need standing height; the low end of the room can take the cistern or storage.
Macerator or gravity
Gravity drainage is silent and needs no maintenance. A macerator lets a WC go where a pipe could not otherwise fall, provided another WC in the house is on gravity drainage.
Rules that apply in Northern Ireland
In Northern Ireland, building control covers new drainage and ventilation, with ventilation set out in Technical Booklet K. The Water Supply (Water Fittings) Regulations (Northern Ireland) 2009 limit a new WC to a 6-litre flush.
