Transparent Pricing
How Much Do Our Services Actually Cost?
We believe you deserve to know what things cost before you pick up the phone. Here’s our honest, no-nonsense guide to waterproofing pricing — what affects it, what to expect, and why the cheapest quote isn’t always the smartest choice.
Why We Talk About Pricing Openly
Most waterproofing companies won't discuss pricing on their website. We think that's a mistake. You're a busy building owner or facilities manager — you need to understand ballpark costs to plan budgets and make informed decisions. Hiding pricing doesn't help anyone. It just wastes your time and ours.
Indicative Price Ranges
These are honest ballpark ranges based on typical projects. Your actual cost may be higher or lower depending on the factors listed below each service.
Flat Roof Waterproofing
£45 – £120+ per m²Depends on system specification, substrate condition, and access. Simple warm roof overlays sit at the lower end; complex build-ups with multiple penetrations and details at the higher end. We specify the right system for your building — not just the one we install most often.

What Affects the Cost?
Waterproofing isn't a one-size-fits-all service. Here are the main factors that influence your final price.
Building Type & Access
A simple single-storey warehouse is very different from a multi-storey occupied building. Access, working restrictions, and safety requirements all influence cost.
Area & Complexity
Larger areas often bring economies of scale. However, complex layouts with many penetrations, upstands, and details increase labour time.
Substrate Condition
A roof in reasonable condition needs less preparation. A badly deteriorated substrate may need significant repairs before waterproofing can begin.
Programme & Urgency
Planned work is more cost-effective than emergency callouts. A flexible programme allows us to schedule efficiently and pass savings on.
System Specification
Higher-specification systems cost more upfront but deliver longer guarantees and lower lifetime costs. We help you find the right balance.
Existing Issues
Hidden problems like trapped moisture, asbestos, or structural defects only become apparent during surveys and can affect the final scope.
The Honest Questions About Pricing
These are the questions our clients really want answered. We don't shy away from them.
Why can't you just give me an exact price?
Because every building is different. We could give you a number right now, but it would be meaningless without understanding your specific situation. What we can do — and what we believe in — is giving you honest ranges so you can budget realistically, then providing a detailed, no-surprises quotation after a proper survey.
Are you the cheapest option?
Probably not, and we'd be worried if we were. The cheapest waterproofing quote often comes from contractors cutting corners on preparation, using inferior materials, or lacking the insurance and guarantees you need. We specify proven, independently certified systems from leading manufacturers — chosen for your building, not our margin — and we stand behind that with proper guarantees and PI-insured design.
What if my budget is limited?
We'll tell you honestly. If your budget doesn't stretch to the ideal solution, we'll discuss phased approaches, interim maintenance, or alternative systems that deliver the best value within your constraints. We'd rather give you an honest plan than oversell and underdeliver.
How do your prices compare to a full roof replacement?
Refurbishment systems — roof coatings, liquid waterproofing overlays, and gutter lining — typically cost 30–60% less than full replacement, with less disruption. That's why condition surveys and proactive maintenance are at the core of what we do — catching problems early saves significant money.
Do you charge for surveys and quotes?
Initial consultations and visual inspections are typically provided free of charge. Detailed condition reports with thermal imaging, core samples, and full specifications are a paid service — because they require specialist equipment, time, and expertise to deliver properly. However, this cost is usually offset against the project value if you proceed with us.
What about hidden costs?
We hate hidden costs as much as you do. Our quotations itemise everything: materials, labour, access equipment, waste disposal, and any provisional sums for work that can only be confirmed on-site. If something changes during the project, we discuss it with you before proceeding.
Think Lifetime Cost, Not Just Upfront Price
The cheapest quote almost never delivers the lowest lifetime cost. A poorly specified or badly installed waterproofing system will fail early, causing water damage, business disruption, and the cost of doing the job again — properly — the second time.
