Frequently Asked Questions
Do I need interior drains or exterior fixes?
We first diagnose where the water is coming from. If it originates outside (grading, downspouts, hydrostatic pressure), exterior drainage is usually best. Interior drains are used when exterior access is limited or to relieve pressure quickly.
Who will be coming out to do my foundation waterproofing inspection?
Foundation Waterproofing 101 has and will never use salesmen. Your inspection will be conducted by Jeff Earl, the CEO and water hydraulics engineer, to guarantee your issues are properly diagnosed and permanently resolved.
How fast can you start after the inspection?
Most projects are scheduled within 1–2 weeks after approval. Emergency water intrusion can be prioritized faster when needed.
Do you guarantee the work?
Yes. Every project comes with a written warranty specific to your scope, covering materials and workmanship.
What does an inspection include?
Our engineer documents moisture readings, structural movement, and provides photos and a written plan of repair. You’ll know exactly what’s happening and how we’ll fix it.

I just wanted to share my experience with Foundation Waterproofing 101. I had been having troubles with one room in my home and I could never get the problem resolved. I hired a leak detection company as I thought there was a busted pipe under my house, but no leak was found. I replaced the carpet in hopes that the issues would “go away”, and behold the rainy season arrived, and my new carpet was ruined by the moisture and wetness in my guest bedroom. I had contacted contractors, plumbers, leak detection companies and none of them could figure out the problem. Therefore, I searched the internet for a company that could help me and I stumbled upon foundation waterproofing 101 online, I called, got an appointment and the owner of the company(Jeff Earl), no less came out and looked at my issue. Jeff Earl, the owner, immediately knew what the problem was immediately. Apparently as he is from the mid-west, these issues are common there and they have a cure that Florida does not. WATERPROOFING!! This system that they have comes with a lifetime warranty, and has solved my problems. I cannot thank Jeff of Foundation Waterproofing 101 enough for saving me, my home, and money. If you are having wetness issues in your home contact Jeff and his company and all your problems will be solved. The team was great, friendly and kept a neat jobsite.Sherry Wallace Tampa fl.
I would like to thank Jeff Earl of Foundation Waterproofing 101 for finding the problem and proving that the problem existed in a home that we recently purchased. The previous owner, or realtor never disclosed that the home had water, wetness issues in the back half of our home. After we moved in we noticed the smell of mildew and dampness on the floors in the back of the home, and thought we had a leak. We contacted a sprinkler company to see if the sprinkler line broke. No, that wasn’t it. We contacted a plumber and a contractor to find the problem and they could not. We checked on line and found Foundation Waterproofing 101 and thought, why not, we tried everything else. Jeff Earl, the owner came out to inspect our home and to unfortunately tell us that the problem that we were having had been going on for years, as the damage to our flooring and walls was obvious to him. He told us that is was a simple, permanent fix that would solve all of our problems. We hired Foundation Waterproofing 101 and was very surprised that there crew of workers was great, helpful and after they were finished, Jeff came back by to check on things and to give us a report that we could use if we chose to go after the previous owner for not disclosing this major issue. The waterproofing fix comes with a lifetime transferrable warranty so that we know that if we ever decide to sell, this fix will cover the new owners and we will not have to worry about litigation. Although I must admit, Jeff has a strong personality, but he was honest and fixed the problem and went above and beyond when he chose to give us a letter to help with litigation. You can not go wrong with Foundation Waterproofing 101. 5 stars for them!!!!!Kelly Mackintosh, Sarasota Florida
I moved here from the northeast and did not realize when we bought our home 7 years ago that it had a crawlspace. Who knew? Well, we have since learned that apparently the water table in Florida is really high so after a year or so, we noticed that our hardwood floors (recently put down) were warping and popping. Therefore, we called a contractor to see why this was happening, well after a bunch of money and no results we decided to look on the internet for someone who handles crawlspaces, and water. We came up with Foundation Waterproofing 101. They were polite, professional, knew immediately what we were talking about, came out did an inspection, shared the issues that we were having and provided a proposal that would solve our problems. Now, I have waited awhile before writing this review because I wanted to see if these guys were the real deal. Well, guess what, they are. We went through the hurricane here I Tampa a few months back and no wetness, no wood warping. Holy cow. They were right and to top it off, they have a LIFETIME TRANSFERRABLE warranty for this. Woohoo!!! No more worries, no more wasting money. Thank you Jeff Earl and Foundation Waterproofing 101 crew.Patty Williams tampa
I am not normally one that writes reviews, but I felt that I needed to for this company. We were under contract to purchase a house that we love and we were told in the home inspection that we had water and mold issues on the main floor of the house. The sellers were not willing to fix it, so we paid the money after closing to have our house looked at by Foundation Waterproofing 101. Jeff Earl, the owner, actually came out himself to look at our issues and knew he could help us. Apparently the water level here is high, the house is lower than some areas of our yard, so water started pooling under the foundation and causing problems. The solution was simple. Waterproof the foundation. This system apparently comes with a lifetime warranty and once we had the job done, they even offered suggestions on how modifying our landscaping will help issues and other things that we could do as well. The team was courteous, and neat, the job was completed without incident and Jeff even came back after to be sure that everything was satisfactory to us. My husband and I are so grateful to Jeff and Foundation Waterproofing 101, for allowing us to move forward with the home purchase and not have worry in the future about it.Steve Apollo Beach
