Ron, I've looked at Certainteed's website, and I, too, like the appearance of the vertical siding.
Egon, I know they add insulation under the siding, at least some of the time, but I really don't need anymore insulation. My only concerns are: (1) no more painting, and (2) keep any moisture out and prevent rotting. However, I've also been told they put a thin sheet of strofoam under the vinyl to keep from driving the nails in too tight; i.e., let the vinyl have the ability to expand and contract with temperature changes.
Goaliedad, I thought Sears used independent contractors, too, (and maybe they do), but the lady I talked to on the phone yesterday said it was Sears employees. I thought they also used independent contractors for in home appliance repair, but the two guys who were here recently to check out our washer and dryer said they're Sears employees; not contractors. And when I was in Pennsylvania, I saw a number of vinyl sided homes with severe fading on the west side, especially if the color was blue. Our current color is something I would call gray and I think I'd kind of like to keep the same color. Actually, I'm inclined to think white is the best, but we have aluminum rain gutters that perhaps would need to be repainted if we changed colors. However, the roofing shingles are gray, so maybe white vinyl with gray gutters wouldn't look too bad. As for being up for the job myself . . . I don't really think so, although I have two brothers who have done that job several times, so with their help, that's a possibility this Fall.
Sears is supposed to have someone here to give me an estimate at 10 a.m. today, so we'll see how it goes. I appreciate everyone's responses.
