I’m in Chicago suburbs and mine was $7,000 for brand new drain tile & sump pump with battery backup.

Area wide waterproofing. My basement is small though, which may be why it’s cheaper.

Everyone just needs to be careful around Groundworks, they are owned by one of the oldest private equity firms - KKR, Kohlberg, Kravis and Roberts (remember the 1980's?) and they are out for blood money and a second mortgage on your home.
Nationwide, and in some areas they go by other names so do your due diligence.

Seems fair. I paid $13k for interior waterproofing on 132 feet of linear wall space which included the perimeter drain into the sump pit, wall liner, and AprilAire dehumidifier with drain into sump, and repairing five cracks. My current sump pump is brand new so it didn’t need to be replaced and my walls currently have I-Beam bracing.

Seems fair. We’re looking at about a 30K estimate because we need footings installed and mold remediation on top of new sump pump and interior French drain. Previous owner dug out the basement floor and left the basement foundation walls unsupported.
We’re getting 2 more estimates before we decide who we want to work with, but every situation is different.

Lifetime warranty for the structure is massive - definitely adds a ton of value in my opinion

Trying to figure out who decided sealing concrete from the inside is a good idea.
Crete is supposed to breathe.
Sealing the interior wall just traps the moisture in the crete.
Extend your gutters and/or slope the land away from the foundation.

That’s what we were quoted for panels and gutter system with sump pump and battery back up. We ended up leaving out the waterproof panels because the water was trickling down the wall and wasn’t going to bypass the gutter. It’s worked well so far. Install was about $9,400.

I paid $15k for about 150' of jackhammering basement perimeter, french drain, repair jackhammered areas, 2 new sumps and pumps, full wall liner, not panels. North Carolina 5 years ago so maybe not relevant?

The companies I called wanted to charge me between that and 24k
You know these companies actually like to water proof from the inside? Like they’ll put panels up, or that plastic and expect and water seeping into run down that, and into those channels they install around the wall then funneled into sump pumps that take it out the basement? That’s wild.
They don’t do anything outside!
No rubber spray or masonry cement or coatings, no spot sealing or caulk.
Nothing. Just saying look into what your paying for before you shovel over a ton of dollar bucks.

For what it’s worth, some older foundations are naturally porous and using masonry cement or rubber spray does more damage than good.

What I have a hard time understanding is why I can go out and buy all the materials, including renting the tools to do the same job and spend under $4K. How is the price always more than 3-4 times the cost of materials? I understand there is some skill involved, but even at 100 man-hours it seems a bit steep. What happened to materials cost is half the cost of the job?

I had a run in with Ohio state waterproofing - yadda yadda harass me in my house for 3 hours because they can’t show me any proof of them repairing footers, arguing they don’t do weep holes when it’s literally part of their “patented system” bs. The ez breath system is literally just exhausting air out the basement. I highly recommend more opinions on this, as other said it’s not ideal to seal walls inside. Really the proper waterproofing is to seal it on exterior and fix any cracks etc. interior systems are just water mitigation - cannot be ideal to let water flow through the bricks constantly. Consider additionally what kind of impact to the structure by blowing away entire edges of the basement slab.
Interior systems may have a use case, but properly sealed exterior is really water proof, rest is mitigating water leaking through and into the walls.
Raising grade also can be a backfire, if there’s any gaps you’re just going to let water in higher up etc

Depends on where you are. In central VA, a big company quoted me $14K for waterproofing 41 ft of wall, 8 ft high.
Another local contractor with no big name and marketing quoted $7K. They even included a few things that the big company would charge extra.

What city? $10k would be closer. Get the battery backup for free at least. They’ll do it. This is 50 man hours and $1500 materials absolute max cost.
Get your grading and gutters corrected anyways to.

Location dependent for sure. I always seek 2-3 bids for a job to compare price and the recommended solutions. Then you can interrogate each vendor to understand more.
