Working in Northallerton
As well as Northallerton itself (DL6 and DL7), we survey in Yarm, Darlington and Thornaby-on-Tees.
Being a smaller town does not change how we work in Northallerton: free survey, written quote, one team. If your Northallerton home has one bathroom and a good-sized main bedroom, an en-suite is often the change that eases the morning queue. If the en-suite in your Northallerton home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size.
Supplies across most of North Yorkshire are moderately hard. A quick wipe of the glass and an easy-clean coating are worth having on a new shower in Northallerton. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
Decisions to make first
Noise
Acoustic insulation in the stud walls and a quiet fan make a real difference when one of you showers early while the other is still asleep.
Refit or new en-suite
A refit keeps the existing drainage and walls. A new en-suite costs more because the walls, waste route, fan duct and electrics all start from nothing.
Rules that apply in England
In England, a new en-suite brings in Part H for the new connection to the soil stack, Approved Document F for ventilation, at 15 litres per second intermittent or 8 litres per second continuous extract, and Part P for the new circuits. The electrician should be registered with a competent person scheme, or the work notified to building control. On a refit, avoid replacing the fan with a less effective one.
