Why your neighbors trust Groundworks

We've earned 33 five star reviews.

"As a structural engineer myself, though my work is in a different sector of construction, I can confidently say that working with Joe Daleo from groundworks was an absolute pleasure. While I don't specialize in residential construction, I knew I needed an expert to thoroughly assess the structural integrity of the foundations of a single family residence. Joe exceeded all expectations. He is extremely knowledgeable in his field and was able to provide valuable insights that I would not have considered. His attention to detail was excellent, and he took the time to explain everything in a way that was easy to understand. Communication was seamless throughout the process—he was always available to answer questions and discuss any concerns I had. Beyond his technical expertise, what stood out the most was his professionalism and friendly attitude. I highly valued his input and felt confident in the thoroughness of his inspection. If you’re looking for a structural inspector who is reliable, skilled, and dedicated to doing a thorough job, I wholeheartedly recommend Joe Daleo from groundworks."

Common Causes of your Crawl Space Problems in Ontario

Moisture and Humidity

Excess moisture and high humidity levels in the crawl space can lead to mold growth, wood rot, and structural damage. This often results from poor ventilation or water seepage.

Poor Drainage

Inadequate drainage systems can cause water to accumulate around the foundation, leading to water infiltration and increased moisture levels in the crawl space.

Open Crawl Space Vents

Open vents allow outside air and moisture to enter the crawl space, which can lead to condensation, mold growth, and pest infestations.

Foundation Cracks

Cracks in the foundation can compromise the structural integrity of your home by allowing water infiltration, which can lead to further deterioration and instability.

Plumbing Leaks

Leaks from plumbing systems can saturate the soil around the foundation, leading to erosion and weakening of the structure.

Understanding these common causes can help you take proactive measures to protect your crawl space and maintain the overall health of your home.
