How to Choose a Waterproofing Company

Start with a visit

A company that wants to see your basement or crawl space before quoting is paying attention to what matters. Water behaves differently at every house.

Be careful with a price over the phone. It may leave out many items.

Notice whether they listen to what you have seen and when it happens.

Ask how they found the cause

A good company can explain where the water comes from and how they know. They should have looked outside as well as inside.

Ask to see photos or readings that support the diagnosis.

A plan that fits only one product for every house deserves a few more questions.

Read the scope

A good proposal lists the method, the length and location of the work, the equipment, the discharge, the restoration, the exclusions and the schedule.

Check that each item you care about is written down, such as a battery backup or a floor patch.

Ask what happens if they find something unexpected.

Check the paperwork

Ask which registrations or approvals your city or county requires for this kind of work and ask to see them. The state and local offices can explain how to confirm them.

Ask for proof of insurance and have it sent from the carrier. We encourage you to confirm these with the people who decide.

Keep copies of the contract, the scope and any change orders.

Think about care after the job

Pumps need testing, drains need flushing and gutters need cleaning. Ask what care the system needs and who can help.

Ask whether the company offers a maintenance visit and what it includes.

A company that explains upkeep honestly is thinking about your long-term experience.

Trust your read of the conversation

You should feel that questions are welcome and answers are plain. Pressure to sign today is a signal to slow down.

Take time to compare at least two written proposals.
