"Don Felton and his crew did a great job installing 2 sumps and a drain system in our basement. They were professional, cleaned up the mess and did it for half the cost of the big name basement waterproofing companies. Don even power washed our deck as a "thank you" for doing business with him. That's practically unheard of these days!"

Foundation Drain Installation FAQs, answered by experts

French drains, sump pumps, and exterior waterproofing systems are common options. Choose one that best suits your property’s needs.

Some questions you should ask before hiring a plumber or drainage installation company include:

  • Are you licensed and insured?

  • Do you have any customer testimonials I can read?

  • How do you handle unforeseen challenges that occur during the job?

  • Is your fee a flat rate or hourly?

  • Do you do the work, or do you have subcontractors?

  • Is everyone who does the work licensed and qualified plumbers?

  • Is cleanup included in the quote?

  • Do you offer a warranty or guarantee on your work?

The cost to install a new sump pump, including materials and professional labor, typically ranges from $1,000 to $3,000. The average cost is often cited between $1,200 and $2,500. Several factors influence the final price, including the type of pump, the complexity of the drainage system, and the installation location. For instance, installing a sump pump in a basement may cost around $1,200, while a more complex installation in a crawl space can cost an average of $3,900. It is important to hire a licensed professional for the installation to ensure quality work, which can impact the pump's lifespan and warranty. Note that these costs are for a new installation; replacing an existing unit is less expensive, typically costing $308 to $748.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.
