"Honestly, I have never had such a positive experience with a contractor. they showed up on time, were friendly, polite, courteous, clean and efficient. In a single day they installed the entire system and left the place clean (within reason). This included jack hammering more than 30 feet of concrete floor and complete water ejection. Unbelievable. They will never be the cheap solution, but they are worth it!"

"I recently had the pleasure of working with Husky Masonry and Paving for the installation of an asphalt pad in my backyard, and I couldn't be happier with the results! The team was incredibly quick and efficient, completing the job in no time without compromising on quality. Not only did they deliver a fantastic asphalt pad, but they also took the time to clean up thoroughly after the work was done, leaving my yard looking immaculate. The professionalism and politeness of the entire staff were truly impressive—they were friendly, respectful, and answered all my questions with patience. I highly recommend Husky Masonry and Paving to anyone in need of paving services. Their dedication to customer satisfaction and attention to detail make them a top choice! Thank you for a job well done!"

Foundation Drain Installation questions, answered by experts

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

Almost any kind of home can have a wine cellar or cabinet installed. You’ll need an area where a concrete floor can be put in, along with the necessary insulation, climate control, and ventilation systems. If you think of yourself as an aspiring sommelier, an underground wine cellar may be ideal, but it will cost significantly more. 

What you choose to install really depends on your budget and how many bottles you’re looking to store.

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.
