What changes the price of a waterproofing job
Raritan Valley Waterproofing does not publish a price list, because two basements on the same street can need very different work. Here is what moves the number up or down.
How many feet of wall, and what kind
Drain tile is measured in linear feet, so a run along one wet wall is a different job from a full perimeter. Wall type changes the work too: hollow block needs weep holes and often a wall membrane; fieldstone may need joints repointed; a poured wall with one leaking crack may need injection and nothing else. That is why the first question at the visit is where, exactly, the water shows up.
Getting in and what is in the way
Every bucket of broken concrete and soil has to leave the house. A walkout door or bulkhead makes that quick; a narrow interior stair makes it slow. Finished walls, built-in shelving, carpet, a finished ceiling over the work, or a furnace and water heater sitting on the wall line all add time to remove and protect. For crawl spaces, the size of the hatch and the clearance inside matter in the same way.
The pit, the pump and where the water goes
A new pit costs more than reusing a good one. Pump choice, a battery or water-powered backup, an alarm, and a dedicated outlet each add a line. The discharge route matters as well: a short run out the nearest wall is simpler than a long line around the house to a spot where the water can drain away and will not freeze.
Extras that are sometimes needed
- An egress window involves cutting the foundation, a well, a window and a town permit.
- A crawl space adds liner area, vent sealing and a dehumidifier.
- Patching and refinishing floors or walls after the trench is closed.
- Electrical work for a pump circuit, which is done by an electrician.
What a written scope should list
Whoever you hire, ask for a scope in writing that names each piece of work and its length, the wall type, the pit location, the pump model and backup, where the discharge ends, what finished surfaces come out and who puts them back, how the debris leaves, and what is not included. Comparing two quotes is only fair when both list the same things.
If you are not yet sure what is wrong, read about tracing a leak first.
