Basement Waterproofing
Dry Otter’s basement waterproofing services are your first line of defense for a dry, moisture-free basement. We use cutting-edge waterproofing solutions to prevent moisture buildup and guard against excess humidity.
Safeguard your Lewisville basement with a waterproofing system to prevent mold, mildew, and other structural problems resulting from leaks and excess moisture.
Crawl Space Repair
Crawl spaces are notorious for excess moisture and pest-related issues that can compromise your home’s air quality and structural integrity. Our Lewisville crawl space repair services offer a wide range of solutions.
Encapsulation is a process that involves lining the walls and floor of your crawl space with heavy, durable plastic to keep out unwanted moisture. We then seal vents for added protection from water, moisture, and humidity.
Other services include insulation, basement cracks, drainage, and leaks. We use only high-quality materials and proven techniques to handle all your waterproofing needs.
Basement Repair
Our basement repair experts can handle all your basement repair needs, like cracking walls, drainage issues, water damage, excess moisture, humidity, and foundation issues.
Neglecting problems will only compound the issues over time, leading to more expensive repairs.
Dry Otter Waterproofing offers a free basement inspection for early detection of potential problems to prevent costly repairs down the road.
Foundation Repair
Every home needs a solid foundation to maintain its structural integrity. Sagging floors, cracked walls, and sticking windows can all indicate a bad foundation.
Dry Otter’s foundation repair experts can diagnose problems and offer state-of-the-art solutions to repair your home’s foundation and preserve its structural integrity.
Mold Remediation
Mold can severely threaten your health, so regular inspections are vital to keeping your home’s air quality safe.
Mold is a general term for fungi that can grow in various colors, like black, green, white, and red. Our mold removal services start by installing a negative air fan in your basement or crawl space to remove potentially dangerous air particles.
Next, we install an air scrubber in your home with the HVAC system turned off to remove any air pollutants, allergens, and microorganisms. Finally, we remove all traces of visible mold so it does not reoccur.

What Our Customers Are Saying
EXCELLENT Based on 367 reviews Posted on Dylan CallicuttTrustindex verifies that the original source of the review is Google. I recently had Dry Otter Waterproofing complete a full crawlspace transformation at my home, and I couldn’t be more impressed with the results. Michael, Will, Josh, and Adam were outstanding from start to finish. Their professionalism, attention to detail, and clear communication made the entire process smooth and stress-free. They installed a sump pump, dehumidifier, full encapsulation, and several other improvements to protect my home from moisture issues. The crew worked efficiently, kept me informed at every step, and treated my property with great respect. The difference in my crawlspace is incredible — clean, dry, and well-protected. If you’re looking for a reliable and knowledgeable team for waterproofing or crawlspace work, I highly recommend Dry Otter. Michael, Will, Josh, and Adam did an exceptional job, and I’m extremely satisfied with the outcome. Thank you to the whole team and God bless you all.Posted on Lou Ellen TAYLORTrustindex verifies that the original source of the review is Google.

Dry Otter recently completed the full climate control and encapsulation of our crawlspace, and the experience was exceptional from start to finish. Huge shout-out to Tyler, Will, and Josh — an absolutely fabulous team. They were professional, knowledgeable, and incredibly easy to work with. They took the time to educate us without ever trying to oversell anything, gave us clear options, and made the entire process seamless. They showed up exactly when they said they would and truly exceeded our expectations. This is one of those investments that gives long-term protection and peace of mind for your home, and I couldn’t recommend Dry Otter more for anyone considering encapsulation or crawlspace work. Outstanding team and outstanding results!Posted on Jennifer MillerTrustindex verifies that the original source of the review is Google. I give 5 stars to Will and Josh. They called me in advance to provide an estimated arrival time, arrived on time, and worked hard throughout the day installing the new sump pump system, adding a new dehumidifier, and repairing the barrier. Thank you Dry Otter for employing such great professionals.
