What to ask mitigation company during onsite estimate
I live in the area known for elevated radon and during home inspection it was confirmed elevated radon levels, I have several estimators lined up in next 2 weeks starting with one tomorrow morning. I just started researching this topic so I am not fully educated yet. What would you suggest to ask estimators to ensure it is good system. I just learned that membrane is usually 6mm and 10mm optional upgrade and even maybe fiber reinforced membrane, fans can be normal AC or EC variable speed and power savings with EC are real advantage what are optional upgrades vs standard basic system. I heard encapsulation for conditioned crawl space is extra. For reference it’s 2 stories house with attached garage 2800sf verbally quotes start in 2100-2300$ for standard package not counting extras. I thought it would be cool if system can be self tuned based on continuous monitoring like if radon high then fan full speed vs if it’s low radon fan slowing down but apparently it is not an option for residential systems, do I need one fan with multiple intake pipes or 2 fans etc. please share your thoughts on this topic and if any extras with doing or it’s money waisted
