The components of the system that are specific to radon systems were purchased online since they could be found cheaper there or were not available at all locally. I made my best attempt at achieving the lowest overall cost, which meant I spent a little extra on some of my items in order to save on shipping.Fantech HP190 radon fan: $120
Rubber connectors: $18
Exhaust cap: $33
Condensate bypass kit: $17
U-tube manometer: $22
Shipping & tax on online items: $36
All of the rest of the items were found locally.
4" PVC Sch 40 pipe, elbows and couplings: $77
Roof flashing: $6
14/2 romex wire: $12
15 amp breaker: $6
Hanging strap, concrete mix, glue: $6
Tools: $40
Tax: $12
All materials total: $405
I didn't keep track of my time spent on the project, but with muliple trips in and out of the attic, concrete hole cutting done the cheap way, and roof flashing work done in the dark, I probably spent close to 30 hours to complete everything. I'm told a contractor would probably charge about $1,200 for the type of system I installed, but as I mentioned in my first post, I prefer to do this kind of project myself. My conclusion: I think this kind of project is well withing the skill level of most DIYers; a bit of planning and testing ahead of time can streamline the project; and like most home projects, there is an opportunity to save a little money.
