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 414 reviews Posted on Reg KingTrustindex verifies that the original source of the review is Google. We needed to have our crawl space "updated" in order to feel good about handing over the home to a new owner after 38 years! The service prior to the sale was thorough, informative and substantiated the costs of each part of the process. When the crew arrived on-site they were prompt, held a consistent clean work area, did a very neat "top drawer" job! Most of all they respected all of our property which is very important when bringing in outside agents! We appreciate the ownership and the young men who completed the work.Posted on David DouglasTrustindex verifies that the original source of the review is Google. Trey Moore, a Dry Otter tech came to our house on 6/3/26 for an annual review. He was punctual, courteous, and thorough.Posted on Joyce KluttzTrustindex verifies that the original source of the review is Google. We had an excellent experience with everyone who worked under our house. The initial inspection done by Mike revealed many things we didn't know, and the report was presented in a way I could understand. The drainage system was done first and fast, followed by a goodly amount of joist and sill repair, professionally done. The encapsulation was done by William and Josh, who did great work and made several trips to our house to make sure we were satisfied. It looks good under there. The new electric lights and switches will make future drain cleaning and pest inspections much easier than before.Posted on Donald NewmanTrustindex verifies that the original source of the review is Google. Outstanding performance. Arrived on time and worked all day. Completed encapsulation on time. Price was competitive. John, Corey, Desmond, Adam, Trey and Patrick were very professional and maintained communications with me. Always knew the status of the project. Great crew all around. Highly recommend Dry Otter for the Denver Area encapsulation. Crawlspace is great.Posted on ScottTrustindex verifies that the original source of the review is Google. Dry Otter has provided me with excellent, professional service since reaching out to them to upgrade my crawl space. Their competent service and technical expertise was always helpful. Also, their response to any questions or help was always met in a very timely manner. I want to call out specifically Adam, Trey, and Heather for all the assistance they provided. They went "above and beyond". I would recommend Dry Otter (and have numerous times) to anyone needing help with waterproofing services. Again, thank you Adam, Trey, and Heather...Posted on Damien KalacTrustindex verifies that the original source of the review is Google.

Thank you!Posted on KathrynTrustindex verifies that the original source of the review is Google. Contacted dry otter for installing a dehumidifier and encapsulation, they promptly scheduled an estimate and were willing to work with me about what I could accommodate in terms of budget. The service was scheduled quickly (about 2 weeks). The crew, Will and Josh (under the Denver NC location), were very communicative and let me know of their arrival time and updates through the day. They were very professional, timely, and friendly. The work completed was very professional and well done. I would 10/10 recommend them to anyone looking for crawl space services!Posted on Fran EarlTrustindex verifies that the original source of the review is Google. troy was every good , he change the battery in the monitor and answer all my
