If you’ve had waterproofing done on your home—whether it was a sump pump install, a French drain, or a full crawlspace encapsulation—you might wonder: “Do I need to disclose this when I sell?”
Or even:
“Will it make my home more appealing, or raise more questions?”
Great questions. Let’s break it down.
First Things First: Always Tell the Truth
Let’s get this out of the way—yes, you should disclose past waterproofing work. Not only is it the right thing to do, but in many states, it’s also the legal thing to do. If the work was done due to water intrusion, that’s a material fact that buyers deserve to know.
And here’s the kicker: trying to hide it almost never works. Inspectors, appraisers, and even nosy buyer uncles who “know construction” will spot signs of waterproofing. Sealed crawl spaces, new sump pumps, fresh vapor barriers—it’s all visible.
Trying to pass off a perfectly dry crawlspace in Oregon without any explanation? Yeah, that raises eyebrows.
Disclosing = Confidence, Not Red Flags
Some sellers worry that disclosing waterproofing work will scare buyers off. But here’s the thing:
Buyers don’t get nervous when they see a problem fixed. They get nervous when they think one’s been hidden.
If you had water in the crawlspace and dealt with it head-on, that’s not a red flag—that’s proof of responsible homeownership.
And if you can show a detailed invoice or warranty from a professional waterproofing company? Even better. Now you’re not just disclosing—you’re reassuring.
It Can Actually Help You Stand Out
Most people don’t want to buy a home that comes with homework. So when a buyer sees that you’ve already taken care of potential water issues, it puts them at ease. One less thing for them to worry about. One more reason to make an offer.
Especially in rainy regions like the Pacific Northwest, showing that your home is already protected against water intrusion could be a selling point.
What to Share (and What Not to Sweat)
When it comes time to disclose, here’s what’s worth including:
- What kind of waterproofing was done (e.g., sump pump, drain system, encapsulation)
- When it was completed
- Who did the work (bonus points for licensed contractors)
- Any warranties or maintenance agreements
What you don’t need to do is get overly detailed or technical. You’re not writing a how-to manual—just give the basics, and let your documentation do the rest.
Yes, it’s absolutely worth disclosing past waterproofing work. Not only because it’s required, but because it builds trust, reduces surprises, and might even help you close the deal faster.
Handled right, waterproofing isn’t a liability—it’s a selling point.
