Hi all, So I'm in the process of getting 3 quotes for re-siding my 2-story colonial with vinyl siding. I've received 2 quotes so far and a ball-park 3rd quote which is being finalized right now. All 3 quotes have used foam-back vinyl siding from Crane, CertainTeed, or Mastic - so all top brands. The quotes also included new 5" aluminum gutters and 2x3 downspouts, soffits, etc. Here's the quotes I've gotten: $14,000 - The "low cost" guy $13,000 - $18,000 - the ballpark I received this morning from a pro who is childhood friend of a nextdoor neighbor who's given me ~5 cords of free wood $24,000 - The smooth talking super reputable company who had done work on a family members home 10 years ago and came back after 8 years to fix a flashing problem "they were ashamed had come from them". What I've been told is that the cost difference in materials from normal vinyl siding to foam-backed siding is between $2,500-$4,000 increase in job cost. However, the entire exterior siding of the home gets an r-4 value (instead of r-1), the siding has less seams in it because its more structurally rigid and therefore comes in longer pieces, and the siding is much less likely to experience any sort of bowing, cupping, breakage, or warping. It does eliminate the use of a beaded-vinyl siding, which I like the style of, but otherwise it's quite nice. So my question is: What should I expect the increase in r-value to mean to me $$ wise each year? Any personal experience in these areas? I'm trying to determine if it's worth it to me. I plan on living here a minimum of 5 more years. Thanks all, Joe P.s. All jobs involve tyvek, tape & seal, which I'm sure will help as well.
