"We have a strange leak in our basement that recurs every time it rains. To figure out the potential source, we called Alpha Structural, and the entire team was outstanding from the get-go. Lisa Hunter first took a detailed account of and keen interest in our situation, and then Gary Coffing came to inspect our house. Gary possesses an incredible wealth of knowledge about foundation and structural integrity, and gave us a very fair assessment of what might be happening, and what we could and should try first. Rather than make a hard sell to engage Alpha in a major investigation, he suggested we first try a few simpler solutions, including fixing the grading of our soil leading to the basement as well as our gutters. Perhaps this won't work and perhaps it will, but the point is he gave us a full account of what may be happening and a number of specific things to try before pulling the trigger on a major structural ordeal. A HUGE thank you to Gary and the whole team. We hope it doesn't come to it, but if we do need to go down the route of major structural work, we will absolutely call you again."

"I returned home from a trip and found water all over my downstairs bathroom and adjoining shed. It was late afternoon and I called Western Rooter who agreed to come out first thing the next day, I had a pretty sleepless night. Rene showed up the next day and assessed the situation and started clean up. Tony soon joined him and the two worked all day until after dark and helped me with cleanup and putting things right. They explained to me what they were doing and why along the way. I felt they charged a fair price. I am so grateful for their service and highly recommend Western Rooter."

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

Basement Waterproofing questions, answered by experts

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.
