"Because of Mikeâ s experience, I felt comfortable in hiring MCF Waterproofing. He and Pat were professional and worked very hard for a reasonable price. They just finished yesterday, and so it may take a while to see how well it works. I know I have less stress now because of the fine job they did."

"Radiant Radon LLC did a great job. I am a Realtor and was representing a client selling house. The buyer wanted a Radon test done before the closing of the house. We were on a tight schedule and Jon was prompt and professional. He did the inspection and then also did the mitigation. Service was well done and affordable with good communication. Client and buyer were happy with results and the house got sold. Thanks Jon! Had a good experience using your company and will reach out to you again for any future Radon testing/mitigation needs."

Basement Waterproofing FAQs, answered by experts

Home improvement grants are available for various groups, including individuals with very low-income housing, elderly people, older adults, and veterans. These grants can cover a range of needs, from accessibility modifications to addressing critical issues that may affect a resident's health or safety.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

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.

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.
