"I am amazed at The quality of their customer service. Before I became disabled, I was employed at the hospital for 28 years and I know how hard-working with the public can be. I really need to give a hats off and a pat on the back to (midstate Basement) systems they came in and did work on my basement and had to come back and adjust some things… Not one time did they roll their eyes or give me a hard way to go about it. Levi ,Judd, Ernest, Jonathan & Adrian were very friendly, courteous & Ernest, Levi and Judd always answered any question I give them and was quick to be of help and to get me scheduled in I would highly recommend Midstate Basements systems to anybody that needs any kind of basement or crawlspace work done. I had my basement done and I’m gonna have to have my crawlspace done in the future and they will definitely be the company I contact. You can’t go wrong by hiring them. Fast, friendly service, each and every time."

"I wish I had hired them first! I hired another company to fix my moving bowed and shearing basement walls. They were primarily a waterproofing company, but said they had the solutions to my issues. 3 months after they were complete, my walls cracked and shifted again. (Note, in the attached photos, the patchwork quilt on the walls was the OTHER company.) OBA fixed my issues the correct way. And they were great at every step. The work crew Caleb, Delontae, and Dylan were fast, efficient, and cleaned up when they were done. Caleb made sure to explain what was happening as they did the work and ask if I had questions. The work was thorough, and I feel good about it. And even better, they'll be out in 6 months to ensure everything is working as it should and make adjustments if needed."

Basement Waterproofing FAQs, answered by experts

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

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.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.

Yes, a crawl space can add value to your home. However, there is a higher chance of it adding value if it is an enclosed crawl space, as this reduces issues caused by excess moisture in the home. That being said, a basement does add more value than a crawl space.
