10 Questions to Ask a Waterproofing Contractor

Is your basement or crawl space damp, musty or moldy? Then you need to find a waterproofer who can solve the water problem so your home is dry, healthy and usable. Selecting the right company can seem overwhelming, but it doesn't have to be difficult. As long as you talk to several contractors and ask the right questions, you'll find a waterproofer who will help you love your home again.

Here are 10 questions you should ask when researching waterproofing contractors.

How long have you been in business?

A waterproofing contractor who has been in business for a long time is likely to be an experienced, trusted professional. Also ask how long the waterproofer has used the solution recommended for your home. A system that has been used successfully for many years is one that has good long-term value.

Are you licensed and insured?

Different states have different laws, but trade licenses, general liability insurance and workers' compensation insurance provide legal and financial protection just in case something goes wrong.

What kinds of solutions do you offer?

Waterproofing companies use a variety of tools and techniques to address water problems, such as French drains, sump pumps, window well and stairwell drains, downspouts, crack and structural repair, waterproofing membranes, erosion control, re-grading and driveway drains. Some companies only offer interior drainage systems, while others provide both interior and exterior solutions. Whether your basement is flooded or your crawl space is smelly, you want to hire a company that offers the solutions you need.

What is causing the water problem?

Water problems may be caused by hydrostatic pressure, negative grading, poorly situated sump pump discharge pipes, high water tables and so on. A waterproofing company's proposed solution should address the source of your home's water problem.

Warranties may cover materials, labor or both. Ask what the warranties cover, how long they'll last, and whether they're transferable to the next homeowner. Check to see if the waterproofer has had to service warranty coverage and, if so, if the company charged additional fees for service or parts. You'll find out if the company stands by its work.

How will the work affect my home?

Waterproofing repairs can be messy. Make sure the waterproofer tells you exactly what the company will do to your home or yard when installing the recommended solution.

Interior solution. A drainage system around the interior of the foundation's perimeter will require cutting into concrete slab floors and may call for drilling into cinderblock walls. In a finished basement, that means several inches of drywall just above the floor will be cut out and tile, carpet or sheet flooring may be cut or removed, too. You'll have to replace the drywall and repaint, and you might need to repair or replace the floor covering.

Exterior solution. A wall and footing drainage system around the below-grade exterior foundation will require excavation and should include the application of a waterproofing sealant to the exterior face of the foundation walls. That means you'll need to redo your landscaping, and you may have to repaint or replace siding.

What is your price estimate?

Ask for an estimate to be presented on the spot or within two business days maximum. Be sure to ask what the price includes. You can also ask about types of accepted payments and whether financing is available.

Are there additional costs?

Waterproofing costs may extend beyond repairs, so don't be surprised if the actual cost is higher than the estimate. Look into these possible additional expenses:

Moving. You may need to move furniture, fitness equipment, toys, lawn furniture and more.

Electrical. If you're getting a new sump pump, you'll need to hire an electrician to install a dedicated outlet.

Drywall, painting and flooring. If you're having an interior drainage system installed in a finished basement, you may have to hire someone to repair drywall, repaint and repair or replace floor covering.

Landscaping and siding. If you're having an exterior drainage system installed, you may need to hire someone to redo your landscaping or repaint or replace siding.

Can I see customer reviews?

A waterproofing contractor with a long list of satisfied customers is a plus. Look at reviews on sites like Angie's List, BBB, Best Pick Reports and Yelp to find out if customers recommend the company you're considering. Note the ratio of positive to negative reviews; a waterproofer with a high percentage of good reviews and a low percentage of poor reviews is generally a good bet. Also check to see if and how the contractor replies to criticism. Even the best contractors aren't perfect, but a waterproofer who responds appropriately to a valid complaint clearly values good customer service.

Selecting the right waterproofing contractor doesn't have to be hard. Just ask several waterproofers these 10 questions and you'll find a company that will solve your water problems so you can relax and enjoy your home.
