Frequently Asked Questions
How long will we be without a bathroom?
Typically 1-3 weeks depending on the scope of work. We work efficiently to minimise disruption. Many clients use another bathroom in the house or arrange temporary facilities.
Do you supply the sanitaryware and tiles?
We can supply everything through our trade suppliers, or you can choose your own from showrooms. We advise on suitability and handle all installation.
What is tanking and why is it important?
Tanking is waterproofing wet areas to prevent water ingress into walls and floors. Critical in showers and wet rooms. We use quality systems like BAL or Mapei and follow manufacturer specifications.
Can you install underfloor heating?
Yes, we install electric underfloor heating mats before tiling. Adds comfort and helps dry the room quickly. Typically adds 1-2 days to the programme.
Do I need Building Control for bathroom work?
Major bathroom work (new rooms, structural changes) requires Building Control notification. We handle all submissions and arrange inspections.
