Transparent Pricing
How Much Does Waterproofing 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.
Triflex Liquid Waterproofing
£45 – £120+ per m²Depends on system specification, substrate condition, and access requirements. Simple warm roof overlays sit at the lower end; car park decks and complex details at the higher end.
Key Cost Factors:
- Roof area and complexity
- Substrate preparation needed
- System build-up (single-ply vs fleece-reinforced)
- Access and scaffolding requirements
HD Sharman Roof Coatings
£12 – £35+ per m²Delcote® full roof coatings are one of the most cost-effective ways to restore an ageing industrial roof. Seamsil® cut-edge corrosion treatment and Delglaze® rooflight systems can be specified alongside. Larger roofs benefit from economies of scale.
Key Cost Factors:
- Roof area (larger = lower per m² cost)
- System choice (Delcote® 10 vs Delcote® 25)
- Cut-edge corrosion extent (Seamsil® 100)
- Rooflight condition (Delglaze® required?)
Plygene Gutter Lining
£80 – £200+ per linear metreVaries significantly based on gutter profile, width, and access. Valley gutters and parapet gutters are at different price points. Includes bespoke fabrication.
Key Cost Factors:
- Gutter profile and width
- Length of gutter run
- Outlet and drainage details
- Access requirements (scaffold, cherry picker)
Soprema Copper Art & Silver Art
£55 – £150+ per m²Premium product commanding a premium price — but significantly less than real copper or zinc cladding. Best suited for projects where aesthetics matter as much as performance.
Key Cost Factors:
- Chosen finish (Copper Art vs Silver Art)
- Area and detail complexity
- Substrate type and preparation
- Architectural detailing requirements
Leak Detection & Investigation
£800 – £4,000+A standard thermal imaging and moisture mapping investigation starts at the lower end. Add electronic leak detection for pinpoint accuracy on membrane systems. Full diagnostic packages for large or complex buildings sit higher. Compare this to the cost of repeated failed patch repairs.
Key Cost Factors:
- Roof area and number of roof zones
- Detection methods required (thermal, ELD, flood)
- Accessibility and covering type (ballast, paving, green roof)
- Report detail and remedial specification
Rooftop Safety Systems
£80 – £600+ per unitGuardrail systems typically £80–£150 per linear metre. Walkways £120–£200 per linear metre. Fall arrest anchors £300–£600 each installed and tested. Free-standing systems avoid membrane penetrations.
Key Cost Factors:
- Type of system (guardrail, walkway, anchor)
- Length of perimeter or access route
- Fixing method (free-standing vs bonded)
- CDM documentation and rescue plan
Condition Reports & Surveys
£500 – £3,000+A desktop report with visual inspection starts lower. Full surveys with thermal imaging, core sampling, and moisture mapping are at the higher end. Price scales with building size and number of roof areas.
Key Cost Factors:
- Building size and number of roof areas
- Survey depth (visual vs full diagnostic)
- Equipment required (thermal, moisture mapping)
- Report detail and remedial specifications
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 systems from manufacturers like Triflex, Soprema, and Plygene because they work — and we stand behind that with proper guarantees.
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?
Maintenance and refurbishment systems like spray coatings and liquid waterproofing 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.
The False Economy
- ✕ Cheapest quote wins
- ✕ No condition survey first
- ✕ Minimal preparation
- ✕ Short or no guarantee
- ✕ Failure in 3–5 years
- ✕ Do it all again + repair damage
The Vanguard Approach
- Proper condition survey first
- Right system for the application
- Thorough substrate preparation
- Manufacturer-backed guarantees
- 20–25 year system life
- Ongoing maintenance support
