How to Find Clients for Waterproofing Contractors: Builders and GCs With Work Now
Waterproofing contractors find clients by reaching the builders and general contractors that award waterproofing, while their projects are still open. Those projects show up first on building permits, months before any bid board; on October 9, 2026, 38,669 of them were inside the waterproofing award window across 25 markets. Builtie, a sales automation platform for construction trades, lists these projects by market and stage and runs the outreach to the builders behind them.
The same four steps, whether the buyer is a builder, a designer, an owner or a company you want to acquire.
Who your clients are
For waterproofing contractors on new construction and larger renovations, the client is rarely the end owner. The general contractor awards waterproofing around the foundation and the building envelope; an envelope consultant or the architect often specifies the system. The client is the company that awards the waterproofing package, so finding clients means finding those companies while their projects are still open.
Where they show up first
| Source | When you see the client | What it covers |
|---|---|---|
| Building permits | Months before the trades are hired | Every project, public or private, with the applicant named |
| Bid boards | When a package is posted for bids | Mostly public and large commercial work |
| Referrals and repeat builders | Whenever they call | Your best clients, but only as many as you already know |
| Directories and ads | When someone is already shopping | Homeowners more than builders |
A building permit names the project months before the waterproofing package is awarded. That is the earliest public sign that a client has work for you, and the one most competitors are not reading.
How to win a new client
- Pick the markets you can serve and pull the permits issued there.
- Keep the projects whose build is from about 10% of the way through the build to about 35%, with the last realistic approach at about 45%.
- Find the builder or general contractor on each permit, then the person who buys waterproofing.
- Lead with below-grade and envelope systems, warranty terms and inspection coordination.
- Follow up when the build moves, and keep the builder warm for its next permit: repeat clients are the cheapest ones.

Frequently asked questions
How do waterproofing contractors find new clients?
Work from building permits: they name the project and the builder months before the waterproofing package is awarded. Keep the projects in the award window, reach the builder's decision maker and follow up as the build moves.
Who hires waterproofing contractors?
The general contractor awards waterproofing around the foundation and the building envelope; an envelope consultant or the architect often specifies the system.
How do I find more clients without more ads?
Repeat builders and new builders found on permits. A builder that awarded you one job will have another permit soon; Builtie flags it.
Is Builtie a CRM?
No. A CRM stores the contacts and deals you already have. Builtie is sales automation: it finds the projects from building permits, times each one to your trade's award window, finds the decision maker and runs the LinkedIn and email outreach. Most customers keep their CRM or job-management tool for the work they win.
