Full services directory How it worksFor prosAbout Get matched Call (866) 582-8523It usually starts with a basement that smells like a basement. The hard part is not the work — it is that every waterproofing company sounds equally sure of itself, and you get one guess. We check licence and insurance before we introduce anyone, and we record the date we checked.

Waterproofing services fall into four groups: exterior work (excavating to the footing, sealing the wall with a membrane and adding a footing drain), interior work (a perimeter drain channel and a sump pump that collects water and pumps it out), targeted crack repair (epoxy or polyurethane injection), and surface and site work (sealers, gutters, downspout extensions and regrading). Interior drainage plus a sump pump is the most common paid job, typically $4,000-$8,000, while full exterior waterproofing usually runs $5,000-$15,000 (HomeCostLab, 2026).
Basement waterproofing costs $3,000-$10,000 on average in 2026, with most homeowners spending around $5,000, or roughly $3-$10 per square foot (Fixr, 2026). Interior perimeter drainage runs $40-$120 per linear foot, exterior French drains $10-$100 per linear foot, sump pump installation $600-$2,500, and single crack injection $250-$1,000 per crack.
Everything we publish on waterproofing, grouped the way homeowners actually search — not the way a company would organise it.
Most sites sell your number to whoever pays the most for it. We check the waterproofing companies we match you with, and we publish the date we checked so you can hold us to it.
We look up the licence with the issuing state or local authority and record the date we checked it.
General liability and, where it applies, workers’ compensation — confirmed with the carrier, not taken on trust.
We read the recent negatives as well as the average, and we look at how the pro answered them.
A licence that lapses drops the pro out of matching. Every record carries the date it was last verified.
Ranges, with the source and the date underneath. Anyone quoting you a single national number is guessing, and you should know enough to notice.
No verified waterproofing price ranges published yet.
We don’t publish a cost until we can show the data behind it. If you need a
number today, the quote form gives you real prices from local companies.
Three ways to get this work done. Here’s what each one actually gives you.
| HomeMatchup | Typical lead site | DIY | |
|---|---|---|---|
| How many companies call you | A short, named shortlist you agreed to | Often 4–5+ at once, sold to whoever buys the lead | None — the work is on you |
| Licence & insurance | Checked against the issuing authority, with a date on the record | Usually self-reported by the contractor | Your own permits and liability |
| What it costs you | Free — pros pay us, and only for a real match | Free, but your number is resold | Materials plus your time |
| Price guidance before you talk | Published ranges with the data behind them | Rarely shown before you hand over details | You research it yourself |
| If it goes wrong | You have a named, verified company and a record of the checks | Hard to trace which site sold the lead | No recourse |

We’d rather show you nothing than show you someone else’s reviews.
Plenty of sites fill this space with reviews scraped from elsewhere, or written for them. We don’t. The first waterproofing review on this page will come from a homeowner we matched, after their work was finished and paid for.

The materials you'll actually be choosing between.
Waterproofing gets sold before anyone finds out where the water is coming from. Treating the symptom indoors leaves the source outdoors. Getting matched takes about a minute, costs nothing, and you can walk away from every quote you receive.
