Ernest Waterproofing is here to give you and your family an ease of mind when dealing with water damage. Statement from our proud owner: " I believe that a good home is built with trust, love, hard work and dedication.

My goal is to expand the longevity of your home and more importantly keep your home safe from water damage.

"Ernesto & his team provided great expertise and quality workmanship throughout a French drain and sump pump installation. When a small pool of water appeared in my furnished basement, Ernesto quickly diagnosed the groundwater infiltration issue and started the project inside 2 days. When we found a leaky pipe that was compounding the problem, he had a plumber on-site within hours to support the additional fix, and later on, connected us with quality support for the drywall and painting recovery. The situation could have been a mysterious nightmare, but Ernesto shed light on the problems and solved them in short order."

"This is the second time that I have used S&S Waterproofing and Foundation Repair. The first time was to fix very large sink holes that were opening up in my front yard, apparently due to underground collapsed drainage piping. This time, when I contacted Steve I asked if they did retaining walls. Steve came to look at the job. I immediately expressed my concern with my limited budget, which Steve completely understood. He offered several options on how to complete the job within my budgetary constraints. We hired S&S Waterpoofing and Foundation Repair to do the job. During each phase of the job, Steve sent me photos of the job progression. He answered any questions that I had almost immediately via text message. Most importantly, he also made sure that my wife was onboard with anything that they were doing. Apparently he knows who controls the money and who the boss is! LOL! Additionally, during the job Steve identified issues with a previous contractors work and addressed those for me as well. Steve is very concerned with customer satisfaction, that is incredibly important to me and my wife! The end result was a beautiful retaining wall. The only thing better than the beauty of the wall is how well it works, drainage is completely handled with ease, even during bad rainstorms! When visitors come to the house, they all ask who built the new wall because it looks incredible! Thank you to Steve and his crew for doing such an amazing job! I am sure this is not the end of our relationship, I will be calling Steve for any of my construction needs in the future! Finally, I just wanted to say, I am the type of person that has anxiety with these types of situations, due to the cost issue, my personal lack of knowledge, and an inability to be able to see the end result before it's accomplished. It is incredible to have confidence in someone doing the work. Someone that keeps me updated, keeps within my budget, makes customer service a top priority. Steve, I can't say thank you enough!"

Cleaning your crawl space is a worthwhile investment for several important reasons. A properly maintained crawl space prevents structural damage by eliminating moisture that can deteriorate wood supports and metal components. It also significantly improves your home's indoor air quality by removing allergens like mold spores and pest droppings that can circulate through your living spaces.
Additionally, a clean crawl space contributes to better energy efficiency by allowing proper insulation installation and reducing humidity levels that force your HVAC system to work harder.
Several warning signs indicate your crawl space needs professional attention. Look for musty odors throughout your home, unexplained increases in allergy symptoms, higher energy bills, visible pest activity, or moisture issues.
Other indicators include sagging floors, warped wood, visible mold growth, standing water, or damaged insulation. If your crawl space hasn't been inspected in over a year, or if you've recently experienced flooding or severe weather, it's advisable to have professionals assess the space even without obvious symptoms.
Most crawl space cleaning projects take between one and three days to complete, depending on several factors. Simple debris removal in a small, relatively clean space might be finished in a single day.
More involved projects that include mold remediation, water damage repair, or pest control require two to three days. For large crawl spaces or those with extensive contamination, the timeline might extend to a week, particularly if additional services like encapsulation are included in the project scope.
You can remain in your home during basic crawl space cleaning. However, if the project involves mold remediation or pest extermination with chemical treatments, temporary relocation might be recommended, especially for household members with respiratory conditions or chemical sensitivities.
Professional cleaning companies use containment procedures to minimize the spread of dust and contaminants into living spaces, but some disruption is inevitable. Discuss your specific situation with your service provider to determine the best approach for your family's needs.
