"Rick, Tyler, and Mark @ Ground Works were great! They were very professional, respectful, reliable, and considerate! They called to keep us updated on their arrival and arrived at the time they told us that they would. Rick evacuated the cracks we had in our basement walls, inspected inside and outside of our house, and gave us recommendations as to how to secure the walls. After making his suggestion to help solve the situation, he shared diagrams and dimensions of the project before giving us a written estimate of the job. Tyler and Mark came out to complete the project. Tyler called to confirm the time that they would arrive, arrived on time, walked with us down the basement and showed us on his tablet, as well as in the basement, what they were going to do. They protected our floors by covering the tile and carpet and did a thorough clean up! They were very professional, respectful, reliable and honest! Thank you for a job well done! I am very impressed and are highly recommend"

Basement Waterproofing FAQs, answered by experts

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Typically, waterproofing a basement should last up to 10 years. However, it’s worth noting that with proper maintenance and depending on the waterproofing method and installation quality, you can probably squeeze another decade out of it.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.
