"I contacted Fausto from Tigasi Insulation to discuss a project in my basement. He arrived on time, and from the beginning, I could tell that he was a professional who takes pride in his work. At the end of the job, Fausto personally asked me to inspect the work that had been completed. I was very impressed with the quality of his work and the excellent job he did. I highly recommend Fausto and Tigasi Insulation to anyone looking for professional and reliable service. Thank you, Fausto, for the great work!"

"Guys came in and worked. No lollygagging or long breaks or any of that just plowed through on a dirty two-day job and their work made me feel a heck of a lot better about the structure of our home. Did great work. The only complaint is that they did not repair a small basement window casing that they pried open to get materials to the basement. I am sure had I contacted them they would have come back and fixed it, but it was not anything nice to begin with and I was able to repair myself pretty easily so I never even brought it to their attention."

"Headly was very knowledgeable and professional. He was also very honest to tell me that the issue was not an emergency as I thought it was. He gave me a lot of information about the water in our basement and advised me to call him if it happens again after a heavy rain. He also checked out and cleaned my gutter while he was there."

"As a realtor, I found Rich from Expedient Environmental Solutions while searching for a client who needed mold remediation. He and his crew did an excellent job at a fair price. They finished on time and left the home clean. So, when I was looking personally to have basement waterproofing (interior french drains and sump pump) along with radon mitigation, I received 3 quotes, of which theirs was the most comprehensive plan, and again not the highest quote overall. They finished the work ahead of schedule by bringing four workers the second day, were respectful throughout and left the area reasonably clean. I'm confident that my days (and nights!) with the shopvac and flooded basement are finally over, and grateful they stand behind their work for a full year. Good contractors are hard to find. Glad I found them. Thanks and I highly recommend!"

"Amazing job, definitely recommend him for your yard or deck work. He came gave me a quote to clean up my flower beds and fix a few rotten woods I had on my deck that looked really bad. He did the job in a few hours and gave me the best price from everyone who gave me a quote."

"Excellent basement waterproofing service! The team was professional, knowledgeable, and worked extremely hard from start to finish. They explained everything clearly, repaired the problem areas, waterproofed the basement properly, and left everything clean when the job was completed. The difference has been amazing ? our basement is now dry and protected, even after heavy rain. Great workmanship, reliable service, and very fair pricing. I would highly recommend them to anyone needing basement waterproofing or foundation repair."

"I recently had Pro Point Masonry and Construction take care of some foundation waterproofing at my home, and they did an excellent job. From start to finish, the team was professional, detail oriented, and made sure the foundation was properly waterproofed. They left the area spotless. I?m really happy with the result and would recommend Pro Point to anyone looking for quality masonry work."

Basement Waterproofing FAQs, answered by experts

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

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.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

If you decide to fill the space around your home’s foundation with landscaping materials, it’s important to consider the aesthetic as well as technical factors like drainage and protection from pests and the elements. Materials such as gravel, rubber mulch, concrete, and brick masonry are all good options.
