Siding Replacement in Vancouver, WA

The old frame sets the tier

The table's first two lines differ by one condition: the door frame coming out. Vancouver's housing is heavy in two decades, the 1970s and the 1990s, which together hold about four in 10 of the city's units. The sliders of the first decade were commonly aluminum, and of the second, vinyl, and the rebate reads those two histories differently: an aluminum or wood slider replaced with a U-0.30 unit is on the $8 line; a vinyl one is on the $6 line. So the first thing VResh Construction records on a Vancouver slider estimate is the frame material of the existing door, photographed, because the utility's tier is set by it and the photograph is the record if the utility asks. An 8-foot slider is roughly 50 square feet at the rough opening, and the utility's own measure of the area is the one that counts; an estimate shows what the utility's published rate would come to on that area, so the owner can weigh the rebate, from a network contractor, against any bid.

The third line is the one a homeowner chooses. A door at U-0.22 is, in practice, a triple-glazed unit, and it earns $10 per square foot regardless of the old frame. The estimate lays the two products side by side, with what the utility's table would pay on each.

What the utility requires

Three conditions sit under the table. The home must be electrically heated, be an existing home, or be a manufactured home. The door must be installed in a conditioned space, so a slider in the wall of an unheated sunroom or a shop is a question for the utility. And the work must be done by a contractor in the utility's Contractor Network. That condition falls on the installer, and as of this writing, VResh Construction is not on the utility's network list, so the rebate is not available for a VResh installation unless that changes. The estimate says so in plain terms rather than carrying a rebate line the utility would not pay. A glazed door is fenestration under the state energy code and must meet U-0.30 with or without the rebate. This is the Vancouver window page's subject, so the $6 and $8 lines start where the code already stands, and the $10 line rebates the step above it.

What a Vancouver estimate from VResh adds to the main sliding door page's installation is the frame photograph, the measured area, and a plain statement of where the job stands with the utility.
