How waterproofing contractors bill
Interior drainage systems are priced by the linear foot of wall treated, with the sump pump, discharge line and any wall membrane listed as separate items.
Waterproofing contractors commonly use "Deposit at signing, balance due on completion", so the invoice is payable the day it is issued. Waterproofing firms usually take a deposit at signing and collect the balance after the concrete over the drain is poured.
Waterproofing Contractor invoicing tips
- List the exact walls treated with their lengths, because a later leak on an untreated wall is often reported as a warranty failure of the whole system.
- Record the pump models, horsepower and whether a battery backup or water-powered backup was offered and declined, since flooding during a power cut is the scenario customers bring back to you.
- Say where the discharge line ends and how far it carries water away from the foundation, because water that is pumped out and runs straight back toward the wall will reappear in the drain.
- Separate interior drainage from exterior excavation and membrane work on the invoice, as the two approaches are priced and warranted very differently and customers often compare them.
Waterproofing Contractor billing disputes to head off
- White efflorescence or damp spots on walls after the job can be condensation, not leakage. Noting the dehumidifier recommendation and the difference on the invoice prevents a warranty callout over humidity.
- Customers sometimes expect a dry basement within days, but wall moisture takes time to drain out; stating that on the invoice keeps the final payment from being held while walls dry.
