Can new siding go over the old?expand_more
It's occasionally done with vinyl, but it hides whatever is happening to the sheathing and prevents the flashings being corrected. In a climate this wet, that's a gamble. Most reputable Clark County contractors will insist on tear-off, and if one offers an overlay, ask specifically why.
Does siding work happen through winter?expand_more
Small repairs, yes. Full replacements need reasonably dry weather because the wall is open at some point in each section. Crews here concentrate the work from late spring into fall, and booking during winter often gets you a better slot and price for a spring start.
Will new siding improve energy efficiency?expand_more
Modestly on its own. The bigger gain comes from adding continuous exterior insulation or air-sealing while the walls are stripped, which is far cheaper to do at that moment than any other time. Worth asking for as a priced option in the bid.
What about the trim, gutters, and paint?expand_more
Clarify all three in writing. Some bids include new trim and corner boards, some reuse them. Gutters usually have to come off and go back on — ask whether that's replacement or reinstallation. For fiber cement, confirm whether pre-finished product or field painting is included.
How long will the job take?expand_more
A typical single-story home runs one to two weeks; two-story or cut-up elevations longer. Rot repair extends it. Expect the house to be wrapped and dried in each evening, not left open, and ask how the crew handles unexpected rain.
