"Robby, Logan and Mason at Basement Authority did a wonderful and professional job for us. They were on time, answered all of our questions and made sure that we were informed and comfortable with all the steps taken during our project (crawl space encapsulation). I would highly recommend them."

"Our water main broke on a holiday weekend and flooded the yard. we were were sure we wouldn't be able to get anyone out to look at it right away. He actually came on the holiday to get a plan together and was back as soon as the store opened on Monday to get materials. Did an excellent job running an eighth of a mile water line in a day at an extremely reasonable rate. I'd highly recommend them!"

"Alford had waterproofed my basement 2 years ago & I've been very pleased with that project. This time, a mouse had gotten in thru an open garage door when weather started getting cold, and had found a hole in a cinder block wall and had babies! I had already trapped and killed 5 before calling Alford. The rep was very polite, professional, knowledgeable, etc. He quoted me a price which was very reasonable but I decided to wait & see...it's been 6 days since last one killed & I still have traps set throughout the house but if I have any further issues, I would not hesitate to call Alford!"

Basement Waterproofing questions, answered by experts

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.
