"My basement is dry and within the 4 -6 weeks after the job the humidity levels where at desired levels and stayed that way. The crew was great and the after care and follow up was above expectations."

"Mid-State Basement Systems came highly recommended by a good friend from Buffalo, NY and they did not disappoint. From start to finish they were very professional yet personable. Larry & Phil in the initial stages of the basement inspection and a reasonable quote. Silvino and his team who done the actual work was incredible, done with absolute excellence. They were here when they said they would be and finished the job a day ahead of schedule. I am thoroughly pleased with this company, first class. I highly recommend them if you need work done on your basement.******"

"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."

"They are great to work with. Communication was superior. They stand by their work. A few years ago I had waterproofing done in my basement and this time they spray foamed the cavities of the basement too. Both times they did awesome work and cleaned up too! I highly recommend this company!"

Basement Waterproofing FAQs, answered by experts

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.
