"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"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!"

"John and his team did a great job on our backyard. John was very knowledgeable and had great suggestions and made sure we got what we wanted in the simple and clean look we were going for. We appreciated that they worked quickly and got the project done in about a week even during the heatwave we were experiencing at the time. He even came back to fix an issue with the turf that had been caused by the heat after the job was completed. It's so nice not seeing any more dirt and we are very happy to be able to fully enjoy our simple, low maintenance back yard."

Basement Waterproofing questions, answered by experts

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

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.

Venting the crawl space can be a good alternative to encapsulation if you live in a dry climate and the moisture problem isn’t severe. You could also try a dehumidifier or install a vapor barrier on the floor, leaving the walls exposed. A new drainage system may eliminate the moisture problem if it is not caused by humidity.
