This is my first home. We built new in Nashville, Tennessee (climate zone 3) so things can get humid in the summer months. Our home is only 3 months old.
We have a conditioned crawlspace with tarp covering the dirt floor. I have noticed that we have a tiny bit of mold growth on some of the wood supports. I contacted a reputable crawlspace company to give us an encapsulation estimate. Below is their quote. My question: Is this an outrageous amount for the work and materials?
1050 sq. ft of CleanSpace Vapor Barrier (covers floor) - $4,000
594 sq. ft of SilverGlo Wall Insulation (2 inches thick) - $1,360
1 Smart Drain - $320
1 Everlast Door - $450
1 Dehumidifier (SaniDry CX Air System) - $1,830
Total Cost: $8,000
The majority of the cost is the CleanSpace vapor barrier.
Our house is brand new. Seems like encapsulating a new crawlspace (that's 3 ft. high) should be cheaper than this. What do you experts think?
