Sealing leaky air ducts in crawlspace w/mastic - DIY?
In a recent energy assessment of our home, one suggestion was to seal the leaky joints in the ductwork with UL 181 mastic and tape.
We're on a budget, so I'm wondering if this is a feasible DIY project? I'm not super-handy, but am a quick learner. One of my concerns is that the ductwork in question is in the crawlspace, which is about 3' high in most places.
Any thoughts? Is it worth the expense to call a pro? Also, any idea of estimated cost? It's a 2300sf two-story house built in 2002, if that helps.
