"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.

Basement Waterproofing FAQs, answered by experts

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to water-damaged concrete.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.
