Waterproofing Estimating Services for Roofs, Walls, and Foundations
Water damage doesn’t show up during construction, it shows up months later, in the form of a callback. Spiron Engineering provides detailed waterproofing estimating services that quantify the sealants, membranes, and barrier materials your project actually needs, so the estimate reflects real protection, not a rough allowance that gets cut when the budget tightens.
Our estimators work across residential, commercial, and industrial projects, delivering the same level of accuracy an in-house team would produce, without the fixed cost attached to keeping one on staff.
Planning & Strategy
Accurate waterproofing quantities depend on a careful review of every exposed surface, not a flat rate applied across the whole structure.

Roof Waterproofing
Membrane systems, flashing, and sealants for the surface most exposed to weather.
Wall & Siding Waterproofing
Water barriers and sealants that prevent moisture penetration through exterior walls and siding.
Foundation Waterproofing
Below-grade membrane and damp-proofing materials that protect a structure’s foundation from moisture and decay.
We also quantify damp proofing scope separately when a project calls for humidity resistance rather than full waterproofing, the two involve different materials and shouldn’t be estimated as if they’re interchangeable.
How We Approach Your Estimate
We review your drawings and specifications for every waterproofing application in the project, then quantify materials by area, roof, walls, siding, or foundation, rather than a single blended number. This matters because underpricing waterproofing scope is one of the most common ways a budget looks fine on paper and then generates callbacks and rework once water finds its way in.
Trades We Cover
We estimate every major trade across the CSI Divisions, so contractors get one accurate, coordinated estimate instead of piecing together numbers from multiple sources.
Questions? You’re covered
Waterproofing protects against direct water penetration. Damp proofing addresses humidity and moisture resistance. The materials and application differ, so we estimate each based on what your project actually requires.
Yes. We can estimate a single application area or the full scope across roof, walls, siding, and foundation, depending on what your project needs.
Construction drawings showing the areas requiring waterproofing. If specifications aren’t finalized, we can work from what’s available and note any assumptions made.
