Crawl Space Vent Cover replacement

Protect your home from outside air and pests

A wooden crawl space access door can warp or rot from the weather outside thanks to excess moisture. They can also leak if not properly installed or sealed. This means your home is vulnerable to unwelcome pests and water damage. The same can be said about old or missing crawl space vent covers. In addition to nasty critters making their way into your home, a crawl space without durable doors and vent covers will also allow outside humid air into the basement or crawl space that will travel to the upper levels of your home. This is known as the stack effect, and it can be the source of mold, mildew and other costly damage.

Thankfully, our replacement crawl space vent covers and doors are waterproof, resistant to mold and will last for many years to come. When paired with a complete encapsulation system, you can rest easy that your crawl space will be completely sealed off from the harmful outdoor environment.

If you are missing crawl space vent covers and doors or want to upgrade what you currently have, contact SouthernDry today! We proudly offer free estimates to Alabama homeowners in Birmingham, Pell City, Hoover, Bessemer, Anniston, Jacksonville, Cullman, Gadsden, Albertville, Jasper, Talladega, Tuscaloosa, Oxford, Montgomery, and the surrounding areas.

Case Studies


Excellent Job for a Fair Price

Had a couple or areas of where water had entered crawl space. John (Owner of SouthernDry) had his men lay French Drain inside entire perimeter of Crawl Space with an addition of a sump pump. Then had Crawl Space Encapsulated. Also, Had a Dehumidifier and Condensation pump installed to prevent future humidity problems. SouthernDry did an excellent job at a fair price. John was always available for any questions I had during the entire process. I would definitely recommend Southern Dry for any encapsulation project.

Water in Crawl Space

We had a severe problem with water in crawl space. We contracted with John to provide encapsulation, and he did a great job. The men who did the work were also great, and I was impressed with how well they cleaned up when the job was completed. A representative from our termite company came today for inspection, and he was very impressed. He said, "whoever did your encapsulation did an excellent job. I was able to go all over the crawl space, which was totally dry, and I could see everything so well due to the white plastic."

Water in Crawl Space

Forgive me for the long review, but great service is hard to find these days. When it's found, it should be celebrated. John and his crew were incredible from day 1. Water was pooling in our crawl space on a new construction and we were eager to have it resolved quickly to avoid the formation of mold and spores and potential health hazards for our family. John came out immediately and assessed the situation, explained all the issues, and developed a plan. We had a guaranteed price in our hands within minutes; fair middle road pricing for extremely high quality work. Many estimates came in 2x higher, just fyi. There was plenty of trash and construction debris left under the house from the contractors; SouthernDry crew removed every piece of debris and leveled out the ground before installing the drains and pumps and encapsulation material. John and his crew returned a week later because they wanted to make a modification to the system that they believed would be more efficient. I would have never known the difference, but because they care about the quality of their work, they made the modifications to ensure the efficiency and longevity of the system. After a month, I finally made it back to the far corner under the house and noticed water pooling under the encapsulation in one area. One phone call and 24 hours later, the crew showed up, assessed the situation and implemented the necessary modifications, installing additional drainage at no additional cost to me. Using SouthernDry was the easiest and best decision we made!

Very Knowledgeable

Our neighbor had his crawl space done first and we met the workers and were impressed with them. Then we called and scheduled someone to come out and give us a quote for our house. Calvin came out and we really enjoyed meeting him and getting to know him. Have talked with Russ a couple of times over the phone and he is very knowledgeable and great to work with. When the work was done, it was so in a timely manner. Great business. Great people to work with. Now we have nothing to worry about under our house. Thanks guys for a job well done.

Very Helpful and Great Attitude

Although the start date was moved due to weather delays on other jobs, the work began on the revised start date. The crew of 3 knocked out the job in a little over a day and a half. Work started 3.12.18 and finished afternoon of 3.13.18. The crew worked diligently with a good attitude. The crew leader as well as the other two workers displayed a lot of hustle. The crew leader was very helpful and had a great attitude. Have not had any issues yet, so I cannot comment on any follow-up/warranty type issues at this time. I would give this firm a very good recommendation.

System Looks Great

They did a great job. Arrived at the scheduled time. Worked quickly and thoroughly. Cleaned up afterwards. The system looks great and appears to be working as advertised. I will call them again if I need assistance with a water issue.

Everyone I spoke with from Southern Dry was top notch.

Everyone I spoke with from SouthernDry was top notch. I prefer doing business with people who are average, regular, down-home folks trying to make an honest living. If you're like me and want someone straight up to give you a reasonable quote on your repairs, call Calvin. They were fast, gave me a date to begin, started that morning early and did a fantastic job. Juan was the foreman on my project and if I had a question he had an answer for me. He was extremely nice and knowledgeable about what was being fixed and done. I was never left in the dark about anything. I had some pretty major foundation issues on one side of my newest house. The back sill plate was rotten and the floor was sagging from no support in the rear. Juan and the crew installed 6 piers, replaced the sill plate, cleaned the crawlspace completely, installed 5 jack supports, encapsulated it all and installed a dehumidifier and battery back up, and made me a 2 new doors in 3 days! So Calvin, Russ, John, Juan, and the other crew, thank you for a job well done. The house looks a million times better! I really appreciate it!
