This is an example of exterior portion of a standard radon mitigation system ran for a real-estate transaction. As always, we took time to professionally install the system so it looks great and will withstand the outdoor elements.

Interior example of a radon mitigation system completed for a real-estate transaction. Notice how clean and inconspicuous this installation is.

This is a good example of an exterior radon fan with a moisture water guard (Extended 10 year warranty). The schedule 40 PVC vent piping was ran to the top of the second story, then around and above the gutter safely venting the radon gas above the home. The homeowner was happy we were able to place the radon fan and vent piping inconspicuously in the rear corner out of site. The fan and piping blend in well against the white siding of the home.

Job Stories From Kalamazoo County, MI
Radon Mitigation - Kalamazoo, MI

Stacey C bought her entire family radon test kits for Christmas. She had read about the dangers of radon and wanted to be sure her immediate families were safe. When all the tests came back, she found that here  own radon levels were elevated to 19 Pico Curies. After a second follow up test that came back at 17 Pico Curies she decided to mitigate. 

We met with the Stacey and designed a radon sub-depressurization system that we felt would significantly lower the radon levels in the home. This included multiple suction points in the basement along with the concrete floor crawlspace. We also included an interior aesthetic package and ran the schedule 40 piping to the garage, up to the attic and out of the roof. With the fan in the attic and discharge pipe through the roof, the entire system is out of site from the exterior. This system also came with an extended 10-year warranty.  

ALS Property Associates, Inc. was happy to help her with this project and feel confident we have lowered the Radon levels significantly in the home. We will follow up on this story once a post Radon test has been completed by the homeowner.

Mold Remediation and Indoor Air Quality Improvements

Michelle reached out to us in an emergency because she had visible mold located in her finished basement. Members of their family were beginning to show side effects that seemed to be linked to possible mold toxicity. There had been a previous leak from the water softener in the utility room which drained into an adjacent finished room causing mold to grow on the drywall, trim, and carpet. This room was right below her daughter’s bedroom who was beginning to show symptoms. 

ALS Property Associates was on the job and ready to help. Upon inspection, we found visible mold growth on the backside of the drywall. Though parts of the trim had water stained, the mold was not showing on the front of the drywall and was hidden from plain sight. We proceeded to build containment around the utility room and the adjacent room with the mold issues. Once the containment was built and sealed off, we created negative pressure, ducting air from the work areas to the outdoors using a HEPA filtered negative air machine. Our team proceeded to remove the affected drywall, carpet, and some of the wet insulation. Following removal, we proceeded and vacuumed all extracted areas, walls, ceilings, floors, and flat surfaces located throughout the contained areas using Nikro HEPA filtered vacuums. After all of the HEPA vacuuming was completed, our team wet wiped all walls, floors, ceilings, and flat surfaces with a hospital grade antimicrobial disinfectant using microfiber towels. The same protocols were used in the daughter's bedroom above the utility room. After removing drywall, cleaning, and wet wiping our team fogged the contained work areas along with the entire basement and areas of the main level with Concrobium Mold Control to eliminate additional mold spores and help prevent future microbial growth. Our last step in the remediation process was to run (4) HEPA filtered air scrubbers for approximately 12-24 hours scrubbing the air of particulates and improving the overall air quality of the home. 

Once the remediation was completed the family began to improve and the mold induced side effects began to subside. Michelle also wanted to improve her indoor air quality of the family’s newer built home. We ended up installing a Breathe EZ Air Filter in her furnace along with an Energy Recovery Ventilator (ERV). The ERV brings in fresh air which is filtered and conditioned and takes stale air outdoors. We set the energy recovery ventilator to a slight positive pressure to also help lower the radon levels which were also slightly elevated. Along with the slight positive pressure, we installed a radon fan in the attic to the already installed pass through radon system that was installed with the home. We are waiting for follow up radon and mold testing but believe we successfully lowered both the mold and radon levels throughout the home to our even below outdoor levels. 

Radon Mitigation with Interior Aesthetic Package

We met Travis at a home he was working on purchasing. After the elevated radon levels were detected he felt it was important to have a radon reduction system installed. Aesthetics were a factor for Travis and he really didn’t want the fan to be visible from the exterior of the home.


Once the sale of the home was finalized we had the opportunity to install the radon reduction system. Our team was able to put the suction point of the radon reduction system inconspicuously in the corner of the basement. We ran the schedule 40 PVC piping from the suction point around the existing gas and electrical lines and out to the garage. The piping was then professionally ran through the wood shelving up to the upper portion of the garage almost hiding the pipe from view.  All of the shelves are still usable and can be moved as needed. We then installed the low voltage radon reduction fan above the attic line and vented it straight through the garage roof. The visible area of the system is the PVC vent extending through the side portion of the roof.


Our team was happy to help Travis and proud of the excellent workmanship completed at his newly purchased home.

Combination Radon Mitigation

Lorri K reached out to ALS Property Associates, Inc because her home tested high for radon. Doug met with Lorri to inspect her home and help develop an action plan to properly mitigate the radon issue in her home.

The home had a small Michigan Basement along with a large dirt floor crawlspace. This crawlspace was under the living area, master bathroom, and bedroom. The radon levels were also reading double digits in the living room on the main floor. Doug and Lorri worked together to design a mitigation system that would efficiently improve the radon levels in the home.

ALS Property Associates installed drainage matting along with 20 MIL Clean Space Vapor barrier throughout the entire crawlspace. The vapor barrier was properly sealed up the foundation walls to help make the barrier airtight. They then created an extraction point in the main slab and connected both the vapor barrier and the basement slab to on exterior radon fan. This created negative pressure under both the basement and the barrier located in the crawlspace safely venting the radon gas up and away from the home. This system was also installed with an exterior aesthetic system for looks and a fan moisture guard (10-year warranty). ALS also installed a Breathe EZ Air filter in the HVAC to filter radon decay products along with other indoor air particulates. Following the installation of the mitigation system, the radon levels have dropped dramatically under the EPA action level and the indoor air quality greatly improved.

Radon Sump Depressurization in Schoolcraft, MI

Collette R found ALS Property Associates, Inc. online. After looking through their website, she decided to have them out as they looked like the right fit. Doug Smith from ALS met Collette and completed a thorough inspection of her home. Through discussion, Collette advised she was concerned with the overall indoor air quality of their home. Due to Covid, the family was spending a lot more time in their home. Doug and Collette sat down together and designed a radon system that met all the family’s needs along with a few indoor air quality products.

The ALS team showed up and professionally installed a complete mitigation system. They used the newly installed sump-pump and water drainage system as the radon extraction point. The schedule 40 pvc piping was ran to the front side corner to an exterior Radon fan. The radon pipe was run along the corner of the home along a gutter and completely hidden from a large tree located on the front corner of the home. The crew also installed a Breathe EZ Air Cleaner along with a Breathe EZ UVC light to improve the indoor air quality of the home.

Collette was happy with the project and relieved her radon levels were significantly lowered. She could also sleep better knowing the Breathe EZ products would filter and prevent mold growth and viruses within the HVAC system creating cleaner breathing air for the entire home.

Radon Removal in Kalamazoo Michigan

Dean B. called ALS Property Associates after an elevated radon test. He was referred to ALS Property Associates from a neighbor who had recently had her radon levels successfully reduced. Dean decided to have Doug from ALS do some additional radon testing with a continuous radon monitor to confirm what his short-term charcoal test he had complete prior. The continuous monitor confirmed that Dean's levels were a bit elevated and he decided to have ALS Property Associates, Inc install the radon reduction system. (Radon Mitigation) 

The system design included drain tile and two sump pits. The ALS team installed radon sealed covers over the sump pump pits and tied into the existing drain tile located under the slab. As Dean requested the team routed the schedule 40 PVC pipe to the West Side of the home to the Legend Low Voltage exterior radon fan, then vented safely above the roof.

Dean was happy with the finished product and shocked at how much lower the radon levels were reduced in his home. The ALS Team is happy with the results and always put the health of their clients first. Their goal is to lower the radon levels as much as possible to lower the risk of developing lung cancer.

Radon Removal with Exterior Aesthetic Package in Portage, MI

Erica S. called ALS Property Associates, Inc after completing an over the counter charcoal radon test in her basement. Her radon levels were quite elevated and she wanted to proceed with installation of a radon reduction system. After meeting with Doug at her home she decided to move forward with the project. Doug did a good job of designing an efficient system and covering all of the details. 

The ALS team proceeded with the installation of the radon system. There is a sump pit with drain tile was ran around the entire basement under the slab and along the footing. ALS was able to depressurize the existing drain tile system by installing the extraction point over the tile and properly sealing the sump pump pit. Erica was worried about cosmetics and wanted the system to have a fresh look on the outside. The team installed the interior aesthetic package which includes a cover over the radon reduction fan and venting the schedule 40 pvc pipe through the soffit and roof instead of around the gutter. She also had the team install the fan moisture guard  (Extended 10-year warranty) for piece of mind. 

The radon removal system (Radon Mitigation / Depressurization System) successfully reduced the radon throughout the home. Erica is happy with the finished product and now feels comfortable spending time in her basement.

Radon Reduction System

Nataile a real estate agent found out after a home inspection the property she was selling had elevated radon levels above the epa standards. She needed a radon reduction system installed for her client and time was a factor for closing. She called ALS Property Associates and Bucky Block was able to come out that day to provide a free estimate. ALS Property Associates from there was able to install a sub-slab depressurization radon reduction system in time for closing on the property. The radon mitigation system was run with schedule 40 piping and vented above the roof line in the rear corner of the property as requested by the buyer. Nataile was very pleased with the timely response and the new homeowner now had safe radon levels.
