Job Stories From Williamson County, TN
Wet Basement Solutions in Fairview, TN

This homeowner was having some major issues in their finished basement space.  The water was seeping in through the walls and the humidity was high.  They were having some major issues, since this was more than just storage, it was a living space too!  They were ahving mold on some of their things, and were concerned that a major water problem could wipe out the entire basement.  They had drywall, which was going to hve to be ripped out along the bottom because it was soaked and molding.  

We cam in and installed the WaterGuard trenching system along the perimeter of the basement.  This collects water as it comes through the walls and channels it to the SuperSump, then pumped outside.  A FloodRing was also placed around the hot water heater.  This device captures water in the event of the leak or burst in the tank, and then drains it directly into the sump well, preventing water damage to the floors.  A SaniDry was also installed to help with the humidity levels in the air.  The drain line for this goes directly to the sump as well, so it never has to be emptied.  No more hauling buckets of water everyday!  Theis basement is now, for the first time, dry and comfortable.

CleanSpace in Franklin, KY

This homeowner called because of water, mold, and debris in the crawl space.  Our inspector found a lot of waste from other contractors underneath the home.  Conditions like this it increases the chance of moisture accumulation, which leads to mold. He also noted mold on the home’s floor joists. Mold in your home is problematic for people with asthma and allergies. It also eats away at the structure of your home.

When our team arrived the first thing they did was remove all of the trash and old insulation. Insulation absorbs water vapor making it heavy. This causes it to sag away from the subfloor rendering it an ineffective breeding ground for mold. They installed our SuperSump pump system and SaniDry  CX to insure that the crawl space remains free of moisture. The finished product is a fully encapsulated CleanSpace that allows the home to maintain healthy air flow.

Dr. Energy Saver in Brentwood, TN!

This family in Brentwood, TN wanted their home to be more comfortable. They spent quite a bit on their home as it was, and were frustrated by the various temperature differences in certain rooms, and cold floors. 

They had a member of our team come and do a FREE energy audit to come up with the best permanent solutions for their home. 

We insulated their attic properly but sealing holes and light fixtures. We used our SilverGlo panels in the basement work shop, and attic. We added Clean Space to their crawl space and made sure everything was sealed from top to bottom. 

Their home now has clean air throughout the house, and their energy bills are going to be less which will pay for their project over a period of time! We can do this for you too!

Dr. Energy Saver in Franklin, TN!

This family bought their home 2 years prior and were living with uncomfortable rooms and sky high energy bills. They wanted to keep the lady bugs out of their attic, and were concerned about the lack of insulation in their attic. Their main concern was lowering their energy bills and had already replaced their 6 HVAC systems and replaced the windows throughout the house. 

After an inspection from Frontier, they began to understand how the whole house is system that works together or against itself depending on how the house is built. They decided to go with our open cell spray foam insulation to seal holes that air was seaping though, and use our higher grade insulation to keep the heated and cooled air inside the house!

Crawl space fungus in Hohenwald TN

After owning this rental home for 30 years the home owner decided it was time to sell. The home owner does not go in to the crawl space and to her knowledge did not have any moisture or mold problems upstairs. After listing the home on the market an inspector told them about moisture and mold concerns in the crawl space. This home will not pass inspections for sale as-is.


Killing the mold under the home was a priority for the home owner.

Water in the crawl space was easy to spot once entering the space. The relative humidity in the crawlspace was 77%. The wood had a mosituere content reading of 18.5%.

Looking back they had noticed a couple soft spots in the floor near the center of the home but had not thought anything of it. These unfavorable conditions and mold eating away at floor joist had weakened the supports.


Treating the floor joist with a powerful cleaning solution, Mold-X2, kills off the mold and fungus growing there.  It was important to not only kill and clean the mold off but also prevent it from growing again. By encapsulating the crawl space the conditions can be controlled making the space intolerable for mold, mildew, and fungus growth.

Lining the crawl space with CleanSpace 20mil plastic vapor barrier will keep rain and ground water out of the space.

Moisture is also found in the air and can effect the condition of the environment. The SaniDry Sedona, a compact dehumidifier, treats the air and pumps moisture pulled from the air to the sump pump liner.

A liner and sump pump collect and pump water out of the crawl space to a discharge line that runs further out on the property, safely away from the home and foundation.


With the crawl space treated and protected the air and wood will be much healthier; creating a healthier environment for the home above. A permanent solution to a scary mold and fungus problem offers value to this home and peace of mind to whomever buys it for their family.

Replacing a basement drain with a sump pump in Nashville TN

Since the flood of 2010 this Nashville basement will flood during heavy rains.

A drain was installed in the basement floor when the home was built this seemed practical since the utilities were there.

In 2010 Nashville had a great flood, even ground water was going any where it could. Homes like this one had water coming in through the drain. Over time as the area grew, land was developed, water routes were altered.

Since this time this home has had flooding with every heavy rain.

Main concern: Water getting in the HVAC unit and causing damage.

The space is also used for storage so the goal was to protect the utilities and personal belongings, providing peace of mind for future rains.


The Solution:

Triple Safe Single Pump System


LawnScape Outlet


The pump liner collects all water and moisture. From there a single M-53 Zoeller cast iron sump pump moves the water through to the discharge lines.

The patented IceGuard prevents wintertime freeze-up of discharge lines, providing an escape route if needed. 

A 4" discharge line is buried and ran 15 feet away from the home at a down grade a LawnScape Outlet caps off the end. This fitting is a way to eliminate visible discharge lines in the yard.

Foundation Repair in Franklin TN


Franklin foundation was settling and needed to be raised.

This Franklin family was concerned about cracks in the brick and wall cracks in the sheetrock.

Another contractor had told them that one wall was leaning out. 

We found the building to have settled ½' in several areas and 5/8' at one corner. We also found a crack no one else had found. It helped explain a crack on the back of the house which had been incorrectly diagnosed by another contractor.

A thorough inspection and explanation set us apart from the competition.   

Considering the load of the home by type of structure, roof, foundation, measurements and the product to be installed, Ten 3 inch push piers were installed at 5-foot spacing.

The 288 Push pier low profile assembly utilizes high-strength round steel tube and a load transfer bracket to stabilize and lift sinking or settling foundations. the foundation bracket is secured against the existing footing and pier sections are driven hydraulically through the foundation bracket and into the soil below using the combined structural weight and any contributory soil load as resistance. Pier sections are continuously driven until a suitable load bearing soil is encountered. At that point, the structure either begins to lift or the target pressure load is achieved. The weight of the structure is then transferred from the unstable soil to the foundation brackets, through the piers, and to firm load-bearing soil or bedrock.

8 Push piers were installed along the exterior of the foundation and 2 on interior corners each driven down to load-bearing soil at an average depth of 10'2.

With the load of the home secure on suitable load bearing stratum, this family can rest easy.

Rotting Wood Foundation Fixed in Franklin, TN

Mr. Lawrence was experiencing foundation issues in his 1980's home that he had just recently moved into. He complained of bouncy and cracked floors. He was worried about the condition of his bathroom floor the most. All of these issues came from moisture in his crawl space, which led to mold growing on his wood foundation. The mold got worse and his wood panels began to rot; this caused the floor above to become "bouncy." If the rotting became any worse and proper support was not installed, the bathroom floor could have easily fallen through. 

Mr. Lawrence and his significant other were on the hunt for the best and most affordable solution. They were looking for companies that provided quality, a great price, and trustworthy warranties. 

They got in contact with Frontier Basement Systems and were happy with the solutions we presented. 
Our inspector, Chris Trigg, talked to them about our SmartJack system and answered their questions, then our crew got to work, 

Carlos Guox and his crew installed our steel SmartJack and steel supporting beam. The SmartJack is a high-capacity, fully adjustable pier that is designed to stop settling and raise your sagging floors!

Thanks to SmartJacks, Mr. Lawrence's joists have enough support to hold the weight of people and furniture AND he no longer is the owner of bouncy floors!

Crawl Space Encapsulation in Brentwood, TN

Heather W. had just moved into her 1973 home with her family and started noticing mold immediately. The mold was from an excessive amount of water leaking into the crawl space and garage. A few of them were experiencing allergies/asthma since moving in, so Heather was worried about her family's health and started looking around for waterproofing contractors. She found us and started looking at our website and products we offered. 
She called us up, because of our free inspection deal and stayed with us for our price and warranty. 

We sent over our inspector Stephen, and he discussed their options with them and they decided on the best one- encapsulating their crawl space.
Our crew installed the CleanSpace Drainage Matting, which becomes a channel for collected water under the liner, CleanSpace Vapor Barrier, which reduces moisture & humidity in the crawl space. They also installed our SuperSump Plus, which is made out of zoeller cast-iron and can pump up to 2,300 gallons of water per hour, and also our SaniDry Sedona, a powerful dehumidifier that will keep the humidity level below 50%. 

Heather and her family now have a dry crawl space and she does not have to worry about mold, mold spores, or dust mites affecting her family's health ever again! We are happy to be able to provide healthy and practical solutions!

Crawl Space Encapsulation in Franklin, TN

Mike G. had mold growing on the 2nd level of his home and had a bad mice problem. He had gotten other companies advice but was still searching for the perfect company. Luckily, he was referred to us and liked our encapsulation process that Robert, our inspector, had talked to him about. When Robert and Mike met, Robert inspected his home and then discussed different solutions, products, and what would be the best option for Mike and his problems. He decided on encapsulating his home with our CleanSpace products, Vapor Barrier and Drainage Matting, to reduce moisture in the crawl space and give water a channel to flow into the designated drain. He also wanted our SaniDry Sedona dehumidifier which will keep the humidity level below 55% (mold, mold spores, and dust mites thrive at 60%) and it also is hooked to a drain, so he doesn't have to worry about a messy cleanup. 

Mike is happy with his dry and clean crawl space that no longer looks inviting for mice to make their home too.
We are thrilled to be able to help Mike and provide him with practical and lasting solutions!

Basement Waterproofing in Fairview, TN

Dennis N. and his wife have had a leaking problem in their basement for 15 years. During heavy rains, water would come out of the back corner of the walls and create puddles on the floor. This created a moisture issue and that led to mold growth and a mildew smell in the space. They had hopes of getting rid of the problem and renting the space out, so they began their search for the perfect contractor to do the job!
They got a few quotes from other companies, but after meeting with our inspector they knew we'd fix up their home for good!
They were excited to get their space back and use it for storage until renting time came, so when our inspector discussed with them our waterproofing products they were right on board!

Our crew installed our WaterGuard System, which collect water from the ground surface and the walls and directs it to the designated drain, our SuperSump Plus, which can pump out up to 2,280 gallons of water per hour, our IceGuard product, which will ensure their basement won't flood if the winter weather freezes the discharge line, and our crew installed our LawnScape Outlet, which has a removable top for easy cleaning and is green to better match their yard!
Lastly, we also installed our stain-proof CleanSpace Wall System, which will help collect water seepage and keep their walls looking fresh and clean!

With the help of our nationally backed waterproofing products, Dennis's basement will stay dry and he can finally rent the space out!
