Terrain-Based Residential Drainage Screening — New Add-On Revenue for Inspectors

Hi everyone,

My brother and I (Construction Tech Expert and Civil Engineer) founded a new company called Low Point Labs. We developed the Drainage Intelligence Platform, a terrain-based residential drainage screening product. It’s currently used primarily by landscape and drainage specialty contractors, but we think it has real applicability for home inspectors as well, and wanted to introduce it here.

The platform generates a Drainage Intelligence Report™ that models how water moves across a specific parcel — flow paths, convergence points, ponding depressions, contributing drainage area for each feature — along with soil and regional rainfall context, all derived from LiDAR elevation data. It’s a genuine analytic tool rather than a canned lookup, so producing an accurate report for a given site does involve some input and configuration on the user’s end.

For inspectors, we see two ways it adds value:

As a client-facing add-on. You offer the report alongside your inspection, price it yourself, and the client pays you directly — you keep the margin. It’s a strong fit in markets with heavy rain events or poor-draining soils, where clients already care about water management and will pay for that insight.

As pre-visit intelligence for your own workflow. Since exterior, foundation, and drainage evaluation is already a required part of most inspections, having this ahead of time lets you walk onto a property already knowing where to concentrate that portion of the inspection, rather than surveying the whole lot cold.

It’s desktop and tablet compatible, generates in minutes, and can be run on-site or ahead of time. The platform can email the report to your client directly, or you can deliver it yourself.

We offer a 30-day free trial with no contract, so you can run it on a few real properties and see how it fits your workflow and pricing before committing to anything.

Happy to answer questions here on methodology, coverage, or applicability to workflows.
