At Radon Hunter we only install with the highest quality recommended materials by EPA Standards.  Below are the products and practices we use and things to watch for to help you ensure you are getting a quality system.

Sub Slab Suction Pit:  We dig a 1 cubic foot pit in the dirt under the slab to allow the best fan performance. The EPA recommends up to a 1 cubic foot pit. Do not fall for companies who claim to dig a larger pit or say the EPA say to remove a number of gallons of soil. These are false claims. If the pit is dug to big it can hurt the structural integrity of the cement slab. That is why the EPA recommends the pit of up to one cubic foot.

Core Hole: We core a 5 inch hole in the slab. This allows for the 4 inch schedule 40 PVC pipe to fit with little gap into the hole. Other companies will claim a 6 inch core with a special adapter allowing more air flow. This is false. The laws of physics are that you can only move so much air through a 4 inch pipe. So using a 6 inch hole gains you nothing. Their special adapter is simply a 6 to 4 PVC adapter that you can buy at any plumbing supply store. The facts are that you loose suction by doing this which hurts the system. That is why the EPA standard says the Manifold piping ID shall be at least as large as that used in any suction point. This makes 6 inch suction points non EPA standard.

Location: We use our expertise to decide the most effective location for the system. These are locations near plumbing chases, drains, and other gaps. Placement of the system is key. Many companies just put it where a customer wants it or where it is easiest. This is not doing the right thing for the customer since it will not have as great of an impact on the radon levels.

Fan Quality: The top two manufacturers of radon fans are Radon Away and Fantech. We Proudly use only Radon away fans. Watch out for two things here. Companies using fans manufactured by any other company then one of these two. Companies selling you a fan upgrade. The fan we use is the same fan as their upgraded fan.

Exterior Wall Penetration: We need to penetrate the exterior wall through the rim joist. We do this with a 5 inch hole saw. We have seen many companies do this wrong. They cut through a floor joist and then the rim joist. This is a major code violation and hurts the structural integrity of the house.

Interior Pipe: We use nothing but Schedule 40 PVC pipe. It has a thicker wall and is more durable then thinner wall pipes. It also is 30 percent quieter then thinner wall pipes.

Exhaust Pipe and Exhaust Point: We use 4x3 aluminum downspout material for our exhaust pipe above the fan. We extend it to the roof line per the EPA Standard and ensure it is at least 2 feet above any opening window or ten feet away from any opening. This pipe is much more cosmetic then PVC pipe up the side of your house. We use aluminum because it will not rust like steel downspout will. Watch for companies that charge for this as an upgrade. Also watch for companies that use plumbing strap in place downspout straps. Plumbing straps are steel and will rust as well.

Sealants: We use only urethane based sealants on all of our suction point seals. We also use pure silicon sealant on sumps and other penetrations. Watch for companies using painters caulk or other sealants as these will crack.

Radon Barrier: We use Duraskim fiber woven radon barrier. It has a fiber cross laminated into it and makes it far more durable then standard 6 mil plastics. The way to tell if a company claims to use this but does not is you can see the fiber weave in the plastic. Watch for companies that use standard 6 mil plastic that you can buy from your local hardware store.

Sump Lid: We custom cut a 1/4 inch clear lexan cover. Watch for companies who use thinner covers or acrylic covers. These will crack if you step on them.

Unfortunately there are many companies putting in lesser quality systems then ours. We have to fix them all the time. We hope this helps to educate you on the quality of the system and the things to watch for when you are shopping for a Radon Mitigation System.
