From start to finish was a professional job, David the sales person was very knowledgeable on how everything works.

We purchased an encapsulation with a dehumidifier through the Jacksonville Alpha Foundation team in February 2024. Our initial site survey was conducted by Christian. He did a great job, showed us the pictures he took, thoroughly explained all of our options and presented a very clean proposal which was great. Ethan was our installer along with his team of Andrew and Matt. They were very obviously well trained and experienced – from the first step of unloading through the installation and clean up. Super friendly, answered all of our questions, shared post install photos -GREAT customer service. They hauled out all of the empty boxes and partially cut pieces. Even though we offered, they didn't use our trash or recycling bins which would have been easy, instead they cleaned up everything and then packed it all out. Today (3/7/25), Devin made an appointment and stopped by for our year 1 of our 5 year dehumidifier maintenance service. He cleaned the filter, pump and checked up on the seams, tape and overall encapsulation install work. He took and shared pictures of what he saw under the house. Today wasn't a sale or attempt to sell – just an inspection visit. Even so, Devin, like the rest of the team, was friendly, showed great customer service and made sure we were happy with the project – even though it wasn't generating any additional revenue. However, his continuation of this cycle of GREAT customer service has locked us in with Alpha Foundation for any work we may need in the future. The entire team – from site survey through year 1 check up – were rock stars. No issues or concerns at any point during the process. I don't believe that this is a one off experience for an Alpha Foundation customer, I believe that this is their business standard. We highly recommend Alpha Foundation as your choice for any and all home improvement work you may need.

Is Crawl Space Encapsulation the Right Solution For Me?
Homeowners in Florida and Georgia are too familiar with the musty smells and humidity from their crawl space. But just because it is common doesn’t make it okay. Crawl space problems like mildew and mold growth caused by moisture can lead to a whole host of problems.
More than 50 percent of the air you breathe comes from your crawl space, so it’s important to keep that space dry and clean.
Your crawl space is more important than you may think. Apart from offering a little extra space under your home, your crawl space also plays a huge part in your health and energy bills. Moisture in your crawl space leads to mold and musty odors plus pests—these problem signs greatly impact your home’s air quality, and elevated humidity causes homeowners to overuse their heating and cooling units, leading to outrageous energy bills.
Alpha Foundations have been sealing crawl spaces with their high-quality crawl space encapsulation system for more than 20 years. We recommend covering your crawl space floor with a vapor barrier, installing a waterproofing system, a sump pump, and in areas where humidity is especially high consider sealing block walls. This high-quality solution mechanically attaches to your concrete blocks, sealing humidity and pests out. A high-capacity, self-draining dehumidifier improves the air your family breathes and makes the whole home more comfortable.
More About Crawl Spaces
Crawl spaces are notorious for their sagging floors, humidity, odors, and flooding. You should call Alpha Foundations for assistance if you notice:
- Rotting wood beams and sagging floors
- Unusually high indoor humidity levels
- Worsening allergy symptoms due to increased humidity
- A musty scent that indicates crawl space moisture
- Increased utility bills and/or the HVAC unit working overtime
- Standing water
- Mold and mildew in your crawl space, basement, or on your first floor
- Condensation collecting on your joists, floors, or foundations
- Cracking foundation
- Pests in your home
Contractors tend to treat crawl spaces as an afterthought, so they often have inadequate support. If your crawl space isn’t encapsulated, mold and water issues could also lead to decaying beams and damaged supports. Soil and clay tend to settle and expand unevenly, but this damage can often be reversed. At Alpha Foundations, we use IntelliJack™ crawl space support posts to provide an effective, durable solution for leveling and stabilizing damaged crawl spaces.
Unencapsulated crawl spaces rarely allow for healthy drainage, so humidity can often transform into severe pooling. Perimeter drains can be placed around your walls and connect to a sump pump. This way, you can deal effectively with flooding. We can include flood alarms, submersible pumps, and vents in this service for a holistic, lasting solution.
Your crawl space is often the only buffer between your house and the earth below, so it has a severe effect on your indoor climate. Insulation can resolve any odor issues while helping your home to achieve a stable temperature. We’ll seal your crawl space with rigid foam insulation to ensure your home is comfortable and more energy-efficient.
Crawl space encapsulation is a quick and easy solution to leave you with a dry, clean crawl space. We use the CrawlSeal™ crawl space encapsulation system to seal off your crawl space from any moisture leaking in. Once your crawl space has been encapsulated, you can start enjoying the benefits. You’ll experience more comfortable air in your home and fewer pest problems, as well as increased energy efficiency to help you save on energy bills.
Muggy air is more than just uncomfortable. It has a direct effect on your health, causing overheating and exhaustion. Crawl spaces generate an average of 0.3 to 2.9 g/m in vapor excess, so it’s unsurprising that most homes that have them suffer from humidity problems. Your crawl space shouldn’t generate more than 55% humidity, but fortunately, there are solutions to resolve all that moisture. Alpha Foundations can fix your home with a crawl space dehumidifier. This will protect your home from fungi and mold overgrowth while simultaneously improving your interior climate.
Why Is Crawl Space Encapsulation Needed?
In Florida and Georgia, the weather, with its high humidity and frequent rain, makes protecting your crawl space even more important. Many crawl spaces still have open crawl space vents and exposed dirt floors. Here we discuss a few of the most common reasons for crawl space waterproofing and encapsulation.
Moisture, Water Damage
Moisture and water are your crawl space’s worst nightmare. Moisture can enter through open vents, a loose or cracked crawl space door, a plumbing leak, or condensation caused by humidity. Regardless of the reason, moisture can cause serious damage like wood rot, mildew, and mold.
Air Quality
Since nearly half the air you breathe comes from the crawl space, ensuring healthy air quality starts there. Both mold and mildew are detrimental, but pest excrement and dust can also cause respiratory problems, especially for those struggling with asthma and allergies.
Structural Integrity
Moisture in your crawl space is responsible for wood rot. Wood rot eats through wooden beams and supports in your crawl space. This causes the wood to weaken. When these important structural supports are damaged, your entire home’s integrity is at risk.
Common Crawl Space Tips & Mistakes
For many reasons, homeowners tend to ignore their crawl spaces until they absolutely need to address them. Over more than 20 years, Alpha Foundation has been helping Florida and Georgia homeowners regain confidence in their homes. Along the way, they have developed helpful tips and mistakes which they’ve noticed in the field.
Crawl Space Tips
- Increased Storage
Although it might not seem like it right now, a crawl space can be a wonderful place to store items like Christmas décor or seasonal outside activity equipment like skis or golf clubs. Once a crawl space encapsulation system is installed, the previously unusable space is transformed into a dry and clean storage area. New doors can be added for easy access if needed.
- Consider The Cost
We understand no one wants to spend money on crawl space repair but choosing the least expensive repair options isn’t always the best bet. If the benefits aren’t worth the cost, why bother? Typically, price depends on the size and condition of the crawl space. Skipping important elements to save cost may not allow you to enjoy the full benefits of an encapsulated crawl space.
- Eliminate Pests
Florida and Georgia homeowners are no stranger to pests in their homes. Frequent visits from the exterminator are likely. One thing to consider, the pests may be entering because your damp crawl space is so attractive to them. Once you seal your crawl space, you’ll be surprised how many fewer pests you have in your home.
Crawl Space Mistakes
- Not Maintaining the Space
Even the most advanced crawl space encapsulation system requires some amount of maintenance. Ensure your crawl space sump pump is in good condition, the vapor barrier hasn’t been damaged, and there are no plumbing leaks. It’s not unusual for crawl spaces to be difficult to get into. However, Alpha Foundation has annual maintenance programs that make the job worry and stress-free.
- Big Box Dehumidifiers
Even with the highest quality encapsulation systems, a dehumidifier may still be needed to remove excess water from the air, especially in humid areas like Florida and Georgia. Skip the big box store units that aren’t rated to remove nearly as much water and require constant attention. Our dehumidifiers are energy-efficient, self-draining, and remove up to 100 pints per day while filtering up to 280 cubic feet per minute.
- Not Repairing Leaking Plumbing
While crawl space encapsulation eliminates water entering from the walls and floor, plumbing leaks are a different story. Before investing in crawl space repair, ensure your pipes are properly inspected by a plumbing professional.
