Installation Process & Timeline

Crew: 4-person installation crew (1 lead, 3 installers) Day 1: — Mobilize, set scaffolding on south and east elevations — Begin aluminum siding removal, south elevation first — Inspect and document sheathing condition as each elevation is stripped — Photograph all sheathing before house wrap installation Days 2–3: — Complete siding removal, all elevations — Replace any sheathing per allowance (client notified before proceeding if allowance will be exceeded) — Install Tyvek HomeWrap, all elevations (bottom to top, lapped shingle-style) — Install FlexWrap at all window and door openings Days 4–6: — Install insulated backer board and vinyl siding, starting at south elevation — Install J-channel, starter strip, and corner posts before panels on each elevation — Progress: north and east elevations complete by end of Day 5 Day 7: — Install soffit and fascia (scaffold already in place) — Install all window and door trim coil work — Final caulk at all penetrations and transitions Day 8 (half day): — Punch list, final inspection with homeowner walkthrough — Scaffold removal and site cleanup — Remove all debris; magnet sweep of lawn for fasteners Total project duration: approximately 8 working days from mobilization. Schedule assumes no significant sheathing damage beyond the 4-sheet allowance. Weather contingency: Vinyl installation will not proceed below 40°F (vinyl becomes brittle and joints don't seat properly). If weather delays occur, Ridgecap will notify client within 24 hours and adjust the schedule accordingly.

Manufacturer Warranties & Certifications

CertainTeed Siding Warranty: CertainTeed Monogram vinyl siding carries a Lifetime Limited Warranty covering manufacturing defects, hail damage (under SureStart protection), and color fade beyond specified limits. The warranty is transferable to one subsequent homeowner within the first 50 years. Full warranty terms provided at project completion. Ridgecap certification: Ridgecap Siding & Exteriors is a CertainTeed SELECT ShingleMaster certified contractor for siding products. CertainTeed requires certified installation for the full Lifetime warranty to apply — we meet that requirement on this project. Dupont Tyvek Warranty: Dupont HomeWrap carries a 10-year limited warranty against manufacturing defects and UV degradation when covered within 120 days of installation (which this project schedule satisfies). Tyvek warranty information available on request. Ridgecap Installation Warranty: 5-year labor warranty on all siding, soffit, fascia, and trim installation. Covers: water infiltration at any installed seam, panel or soffit separation, fascia pull-away from substrate, and trim delamination. Does not cover impact damage, acts of nature, or settlement-related movement of the home structure. Color-fade note: CertainTeed Hearthstone is a through-body color, not a surface coating. Fade is covered under the SureStart protection for the first 10 years; LRV (light reflectance value) must remain within specified limits. Dark colors fade faster — Hearthstone is a medium tone and well within low-risk range for the Midwestern climate at this address.

Exterior Siding & Trim Proposal Tips

  1. 1

    Price by the square, not the square foot — and show your math. One square equals 100 square feet of wall area. Vinyl mid-grade runs $350–$550 per square installed; fiber cement runs $700–$1,100 per square installed. Those ranges are wide because story height, corner count, window trim complexity, and existing substrate condition all affect labor. Break out material cost per square, labor per square, and then add line items for soffit, fascia, trim, and house wrap separately. A client who can see $420/square for vinyl panels versus $88/LF for fascia board understands what they're buying. A lump sum just invites negotiating on the total.

  2. 2

    Specify the house wrap product and method — it's your moisture warranty backstop. Tyvek HomeWrap and Huber ZIP System are both acceptable, but they install differently and have different tape requirements. ZIP System requires ZIP tape at all seams and openings; Tyvek requires proper lapping (6-inch horizontal overlaps, 12-inch vertical) and compatible flashing tape at windows. If you don't name the product and describe the installation method, you have no defense when a client calls about moisture intrusion two years later. Write it in the proposal: product name, overlap dimensions, tape specification at windows and penetrations, and how you handle transitions at doors.

  3. 3

    Soffit and fascia are their own scope — break them out or you'll price them wrong. Soffit is measured in square feet (horizontal ceiling of the overhang); fascia is measured in linear feet (the vertical board at the roof edge). Replacing 40-year-old aluminum soffit and fascia while you're re-siding is smart — it's the same scaffold, same crew, same day — but soffit and fascia have their own material cost (vented aluminum soffit, aluminum fascia coil stock or pre-bent fascia) and their own labor rate. Bundle them on the proposal as a separate line, not buried in the siding square price. If the client wants to defer soffit and fascia to next year, they can — and you've made it easy to subtract that scope without renegotiating the whole job.

  4. 4

    Fiber cement and vinyl are not interchangeable — tell clients the real trade-offs. Vinyl is lower cost, completely maintenance-free, and won't rot or sustain insects. Its weakness is impact resistance and appearance at close range — it can dent, and the hollow sound when knocked is obvious to buyers. Fiber cement (James Hardie, LP SmartSide) costs 40–70% more installed, requires painting every 10–15 years, and adds significant weight to the structure, but it looks like real wood, holds paint well, has a Class A fire rating, and is the material buyers in upper-tier markets expect. If you're quoting a neighborhood where comps are $600K and above, lead with fiber cement and explain why. If you're quoting a rental property owner, vinyl is probably correct. Put the recommendation and the reasoning in the proposal.

  5. 5

    Manufacturer installation certification matters for warranty — put it in the proposal. James Hardie's ColorPlus warranty (30 years on pre-finished panels) requires installation by a Hardie-certified contractor following Hardie installation requirements, including specific nail patterns, minimum clearances from grade and roofing, and caulk at butt joints. LP SmartSide's 5/50-year warranty has similar requirements. If you're a certified installer, say so and name the warranty term. If you're not, you can still install the product, but the client doesn't get the full manufacturer warranty — and you need to say that clearly before they sign. Burying this creates liability when the client files a warranty claim three years out and discovers the installer wasn't certified.
