Working in Helensburgh
As well as Helensburgh itself (G84), we survey in Greenock, Vale of Leven and Dumbarton.
Being a smaller town does not change how we work in Helensburgh: free survey, written quote, one team. If you live in a Helensburgh flat, check your title deeds and any deed of conditions before planning a new en-suite, as agreement from the other owners or the factor is often needed for new drainage and vents. We quote new en-suites in Helensburgh only after checking the drainage route on site, so the price reflects the work your house actually needs.
Most of Argyll and Bute is supplied with soft water. If that holds for your street in Helensburgh, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- A shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
Decisions to make first
Night lighting
A mirror light or low-level LED strip on its own switch lets you use the en-suite at night without the full glare of the ceiling lights.
Door type
An outward-opening door frees floor space inside. A sliding pocket door saves space on both sides but needs a stud wall long enough to take the cassette.
Rules that apply in Scotland
In Scotland, forming a new en-suite may need a building warrant because it creates a new bathroom and alters drainage; refitting an existing one rarely does. The Technical Handbook uses the same 15 litres per second extract rate for a bathroom, and the electrics should be tested and certified to BS 7671.
