"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."

"Angel and Andrew did a great job on raising the concrete on my patio. One side was sinking which caused the other side to lift up. They were able to even out the cement so now it looks great. Thank you for working so hard to fix it."

"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

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.

The purpose of soffits is to circulate air, so a blocked soffit means the air in your attic becomes stagnant. This can lead to a number of problems, mostly moisture-related, that can cause damage to your health and your home. The good news is that unclogging soffits is relatively straightforward, and if your attic is easy to access, an easy DIY project.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.

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.
