Working in Boston
We cover every part of Boston, including PE21, and nearby Spalding (14.1 miles) and Sleaford (16 miles).
Homes in and around Boston vary, so we look at the floor, the walls and the water system before we price anything. If your Boston home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options. If your Boston house has a combi boiler, a loft shower can usually run on mains pressure without a pump.
Water across much of Lincolnshire is hard. If your supply in Boston is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A check of your hot-water system and of the pressure and flow you actually get at loft level
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
Decisions to make first
Where the shower goes
Under the ridge or in a dormer, where the full height is. A walk-in shower with a single panel is usually easier to fit to a roof line than a framed enclosure.
Eaves storage
Low cupboards built into the slope behind the WC or basin take clutter out of the room and hide the pipework.
Rules that apply in England
In England, new drainage and a new connection to the soil stack fall under Part H, a new bathroom needs extract of 15 litres per second intermittent or 8 litres per second continuous under Approved Document F, and new circuits are notifiable under Part P. If the work includes an unvented hot-water cylinder, it must be fitted by a G3-qualified installer.
