"I highly recommend this contractor. They were highly professional in every way: they always came just when they said they would, they did exactly what they said they would, they were great at solving problems that arose during the basement waterproofing project, and they did a really good job of keeping us informed multiple times a day about the progress of the project. The crew that handled our project was outstanding. We were especially appreciative of the work done by the foreman, Dan. Just great all around work."

"John from Global Dwelling did our initial assessment. I appreciated him taking time to explain all the work that needed to be done and why. His team came in a few weeks later and were really amazing. I think insulation work is super messy and will leave a ton of debris everywhere. I was pleasantly surprised to find a ton of cloth coverings coming in to cover everything and found no major dust/debris in the house when they were done. The guys were very nice and thoughtful while in the house. The work completed was completed on time and our house is definitely more comfortable. Our finished basement is no longer a freezer and the house doesn’t “sneeze” when there is a high wind. I have already recommended them to my neighbor for when he’s ready to insulate his attic!"

You can see that we've insulated and air sealed the rim joists in this picture in addition to the B2B paneling.
You can see the main attic ducts have been spray foamed in this photo.  This keeps the warm air warm as it travels through your cold attic in the winter time.

"Mold Buster's got it right. Chris and Sayde and the crew are hard working honest people who know what they are doing. Not only is Chris knowledgeable about this service, he is honest and forthright. He is committed to your total satisfaction with the job. We hired him after we inherited my father's house/cottage. The roof had been leaking and moisture had been getting into the basement and exterior walls, causing mold growth throughout. Chris quickly identified all the problem areas, suggested various solutions, worked with us to set up budget and schedule, answered all our questions, and completed the job in a timely fashion. Bottom line is we are very pleased with the result, would use Chris again, and recommend him highly."

Basement Waterproofing FAQs, answered by experts

If foundation problems are not fixed, they will likely worsen over time, leading to more complex and expensive repairs. Neglecting a damaged foundation can cause a range of issues, including:

  • Structural Damage: Minor problems like small cracks can escalate into major structural issues. This can damage the house above the foundation and, in severe cases, lead to foundation walls caving in or a total collapse.

  • Water Damage and Pests: Moisture and water intrusion can cause flooding, mold growth, and pest infestations.

  • Health and Safety Risks: Mold can lead to poor indoor air quality and other health risks, while structural instability poses a significant safety hazard.

  • Reduced Home Efficiency: A compromised foundation can negatively impact your home's energy efficiency.

To avoid these escalating problems and costs, it's best to hire a foundation repair company to address any issues as soon as you become aware of them. The earlier problems are discovered and fixed, the lower the repair cost will likely be.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

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.

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.
