Chose Alpha Foundations Chris V and Matt W to stabilize the concrete area under my spa and pool area and Mike and Kesly to fill the cracks on my pool deck and add poly to seal. After a few hiccups which they solved quickly they did an excellent job. Explained everything as they went along and answered all my questions. Very knowledgeable and professional. Cleaned the area of any debris when they were finished. I would highly recommend.

Our 100 year old house sustained significant foundation damage from Hurricane Helene in August 2024. Half of the supporting piers in our crawlspace were washed away by storm surge. Half of the house was suspended in the air without support. I contacted 3 different foundation companies for quotes. By far, Alpha Foundations is the best. An appointment was scheduled immediately with Johnnie the site estimator. He showed on time and communicated during his trip where he was and when he would arrive. He spent about 3 hours at our home during the evaluation. He was the only one of the 3 companies we contacted, who climbed under the house. He spent 90 minutes in a dark, damp and narrow crawl space. He did a thorough evaluation. He discussed with me and my wife his findings and recommendations. Prior to leaving he left a detailed quote and estimated timing to complete the project. We selected Alpha Foundations to repair our home. A repair date was scheduled and the office communicated with us multiple times prior to the repair date. On the repair date, Luke, Ryan and Jordan arrived as scheduled. They were courteous, friendly and very professional. Luke was the job foreman and reviewed the repair plans in detail. He was available for questions throughout the process. The crew was here for 3 days and did a fantastic job. Our home had a 4" drop in the family room, which was corrected. The sloping floors throughout the house were gone. Fantastic job done by these young men. Alpha Foundations is a 5-star company and will provide on-time, professional and excellent service. I highly recommend their company…….and I hope to never need this time of repair again.

The Orange Park, Florida Office is top flight from the initial call, to the field visit by Mr. Clark to determine the recommended solution. In advance of the foundation work, we prepared the area for the Technicians, which is very helpful in expediting the work. Tyler and crew arrived at 8:30 am, followed by Brandon and crew at 11:00 am, all work was completed by 12:30 pm, and the final result was perfect. Pictures show that you would never know technical work that Alpha Foundation provides ever happened. Mr. Clark and both Crews are professional, experienced, and excellent ambassadors for their Company. We highly recommend Alpha Foundations.

Alpha installed piers at our residence to stabilize the foundation. During their visit, it was noticed that another corner of the home had cracks and also needed stabilization piers. They were able to take care of the additional work while on site so we did not have to go through the permitting process again. They also repaired our sprinkler, which was not their fault, just to provide good customer service. They cleaned up our property afterward and completed all work in a timely manner. Steven, Isaiah, David, and inspector Brandon C were very pleasant and professional.

After Hurricane Milton we had water intrusion that forced us to remove the carpets in each room and replace the flooring. When we removed the carpet, we found a crack that went from one corner to the next in one of the rooms. Lance was our sales guy, super knowledgeable, easy to talk to, and worked with us on options since our insurance wasn't going to cover it. Although some settling cracks are probably ok, I had a feeling this one wasn't. We decided to do the hydrophobic injection under the foundation. Tory came out to do the work. He was on time, very responsive, super nice. Everything moved along smooth. Tory noticed that it seemed like there was a bit more foam injected than he expected- which confirms there was a larger void in that area than we expected. Tory patched the holes and I can't even tell anything was done! Looks great! I think of this room as now the strongest room in our house. I'm SO happy I got this done. I would do this again if we ever needed to in our next house. Thank you!!!

I would highly recommend them to you and your family if you need foundation work done. Don't shop around and waste your time and call Alpha today. Thanks Malik and team you guys were awesome.

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.

Ductwork and insulation in a crawlspace with reflective material and exposed beams.

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.

Rotten Floor Beam

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.
