Working in Grangemouth
We cover every part of Grangemouth, including FK3, and nearby Falkirk (2.5 miles) and Alloa (7.7 miles).
Being a smaller town does not change how we work in Grangemouth: free survey, written quote, one team. Where your Grangemouth home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go. For a new cloakroom in Grangemouth, the first thing we look at is where the nearest drain or soil stack runs.
Water across much of the Forth Valley is 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
- 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
- Compact sanitaryware: a short-projection, back-to-wall or wall-hung WC and a corner, wall-hung or slim vanity basin
- Lighting wired by a qualified electrician, tested and certified
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.
WC style
A wall-hung WC on a frame gives the most floor space and looks neat. A back-to-wall pan in a short furniture unit is easier to fit against an uneven wall.
Rules that apply in Scotland
In Scotland, forming a new WC that alters drainage may need a building warrant, while refitting an existing cloakroom normally does not. Water fittings are covered by the Scottish Water Byelaws 2014, and electrics should be tested and certified to BS 7671.
