What to check before you hire a waterproofing specialist
- Ask which BS 8102 approach will be used and why
- Ask whether the system includes a sump and pump, and what happens in a power cut
- Get the guarantee in writing, ideally insurance-backed for larger jobs
- For showers and wet rooms, ask what tanking system is used under the tiles
- Check that surface water and gutters have been ruled out first
What affects the price
- Area and depth of the space
- Water pressure and whether a sump pump is needed
- Preparation, including removing old plaster or finishes
- Access
- The finish required afterwards
Call-out fees usually cover travel and the first period of labour. Ask whether yours does, and what the hourly rate is after that.
How to compare quotes

Compare what is included, not just the headline price. The cheapest quote often leaves out preparation, making good or certification.

Frequently Asked Questions
Why do waterproofing quotes vary so much?
Quotes differ in what they include: preparation, parts, making good, certification and guarantees. Ask for an itemised quote so you can compare like for like.
Do these prices include VAT?
Yes, the guide ranges include VAT. Always check whether a written quote is inclusive or exclusive of VAT.
Is it cheaper to book outside peak season?
Often, for planned work. Emergency and out-of-hours call-outs cost more at any time of year.
What is the difference between damp-proofing and waterproofing?
Damp-proofing resists moisture. Waterproofing resists water under pressure, as in basements below ground level.
Do I need a sump pump?
If the system collects water, like a cavity drain membrane, a sump pump removes it. A battery backup is recommended.
Can a shower leak without me seeing it?
Yes. Water can get through grout and failed seals into the floor or wall for months before you see stains.
