Replacement Window and Patio Door Installation
Replace 8 windows and 1 sliding patio door at 4412 Fernwood Drive. Windows: All 8 existing double-hung windows to be replaced as full-frame tear-outs. Site inspection on 3/14 confirmed the following: existing wood frames on north and west elevations show moisture damage in sill areas, with one sill (bedroom 2, north) showing soft wood extending 4 inches into the rough opening. Full-frame replacement allows damaged wood to be removed and treated before new units are installed. South and east elevation windows show no rot; full-frame is recommended anyway to allow proper flashing and air sealing on all units, and to install new exterior trim to match the planned siding refresh next year. Patio door: Existing sliding door (6-foot opening) to be replaced as full-frame. Old door shows gap at threshold and failed glazing seal (visible fogging between panes). New unit to match rough opening; no structural changes required.
Windows (8 units): Model: Simonton 9800 Series double-hung, double-pane low-e with argon fill Frame: Fusion-welded vinyl, white interior and exterior Glass package: Cardinal 366 low-e coating, argon-filled U-factor: 0.22 | Solar Heat Gain Coefficient (SHGC): 0.20 Meets ENERGY STAR requirements for Northern Climate Zone Screen: Full-screen on all units, fiberglass mesh, removable Sliding patio door (1 unit): Model: Simonton Patio Door, 6/0 x 6/8 sliding, XO configuration (fixed panel left, operating panel right) Frame: Vinyl, white, multi-point locking hardware Glass: Same Cardinal 366 low-e / argon as windows U-factor: 0.27 | SHGC: 0.22 Meets ENERGY STAR Northern Zone Screen: Full-height sliding screen included Note on fiberglass alternative: Soft-Lite Elements fiberglass double-hung (comparable glass package, U-0.20) is available at $140 per unit upcharge. Fiberglass is dimensionally more stable than vinyl in high-temperature-swing climates. Recommended if you plan to own the home 15+ years. Ask us to requote if interested.
All windows: Full-frame tear-out. Process for each opening: 1. Remove existing window, trim, and frame to rough opening 2. Inspect rough framing — treat or sister any compromised framing members (bedroom 2 north sill to be reframed; included in scope) 3. Install self-adhering flashing tape at sill and up jambs to weather-resistant barrier 4. Set and shim new window unit; verify plumb, level, and square 5. Foam-seal gap between frame and rough opening (low-expansion foam) 6. Install new exterior aluminum casing (primed, paintable) and caulk with Tremco Vulkem 116 7. Re-install or replace interior wood casing; nail and caulk 8. Final check: operation, lock engagement, screen fit Patio door: Same process. Threshold flashing to extend under door to exterior decking. Threshold height to be confirmed on site before installation — if deck boards require notching, that is included. All old units, frames, and debris hauled off-site and disposed of. Interior protected with drop cloths; work areas vacuumed and wiped down at end of each day.
Windows — 8 units (full-frame, Simonton 9800 series): Bedroom 1 (east, 28x54 DH): $1,140 Bedroom 2 (north, 28x54 DH): $1,140 + $180 sill reframe = $1,320 Bedroom 3 (east, 24x36 DH): $980 Living room (south, 36x54 DH): $1,220 Living room (south, 36x54 DH): $1,220 Dining room (south, 28x48 DH): $1,100 Kitchen (west, 24x36 DH): $980 Basement egress (north, 30x24 DH): $940 Window subtotal: $8,900 Sliding patio door — 1 unit (6/0 x 6/8, full-frame): Door unit and installation: $2,640 Deck board notching allowance (if needed): included Patio door subtotal: $2,640 Project total: $11,540 All per-unit prices include: unit, full-frame installation, new exterior aluminum casing and caulk, interior casing reinstallation, foam air seal, low-expansion foam, flashing tape, haul-off of old units. Excludes: interior painting, exterior painting of new casing, blinds or interior window treatments. Payment: 30% ($3,462) at contract signing, 30% at project start, balance due at completion walkthrough.
Lead time: 3 to 4 weeks from signed contract to installation start (window order lead time; Simonton ships in 15-18 business days). Installation: 2 days with 2-person crew. Day 1: all 8 windows. Day 2: patio door, punch-list, and cleanup. If interior casing on any window requires more than standard reinstallation (e.g., existing wood is damaged beyond reuse), that window may extend into a third half-day — we will communicate this during installation. ENERGY STAR documentation: We will provide the certificate of installed products for tax credit filing. The federal Energy Efficient Home Improvement Credit (25C) covers 30% of qualifying window costs, up to $600 per year. The Simonton 9800 units on this proposal qualify. Consult your tax preparer. Warranty: Simonton product warranty: Lifetime on frame and glass seal, transferable to one subsequent owner Clearview installation warranty: 3 years on labor — air and water infiltration at installed openings, screen fit, hardware operation Sill reframe (bedroom 2): 5 years on structural work Exclusions: damage from impact, settlement cracks in surrounding drywall, or failure of any existing components not part of this installation scope.

Create Your Free AccountQuote U-factor, not just frame material. Homeowners hear "double-pane" and assume that's the spec. It isn't. A double-pane vinyl window can be U-0.28 or U-0.17 depending on the glass package — and that difference will show up every month on their heating bill. Put the U-factor in the proposal. ENERGY STAR requires U-0.30 or lower in most northern climate zones. If your window meets that threshold, say so. If it doesn't, the client deserves to know.
Full-frame and insert are not the same job. An insert replacement drops a new window unit into the existing frame — one crew, two hours per opening, no interior patching. A full-frame tear-out removes the old frame down to rough framing, which requires new exterior trim, interior casing, drywall repair, and sometimes structural work if the old frame is rotted or undersized. An insert job on a rotted sill is a callback waiting to happen. Inspect the existing frames before you quote anything. If you find rot, quote it as full-frame and explain why in the proposal. Clients who understand what you found will pay for the right fix.
Frame material is a decision with real trade-offs — tell clients what they are. Vinyl is the low-maintenance, mid-price default for most residential jobs. It doesn't rot, doesn't need painting, and holds its U-factor well over time. Fiberglass costs 30 to 50 percent more but doesn't expand and contract like vinyl, which matters on south-facing exposures in climates with wide temperature swings. Wood is the most thermally efficient frame per inch but requires ongoing maintenance and is wrong for anyone who doesn't want to paint windows. The client choosing between a $380 vinyl and a $620 fiberglass unit needs to understand what they're actually deciding — not just which number is smaller.
Per-unit pricing beats a single lump sum. A proposal that says '$14,400 — 9 windows' gives clients nothing to evaluate. One that shows unit costs by window type lets them make decisions: maybe they drop one casement for a picture window, or pull the bay window from the project scope until next year. Lump bids look like you're hiding the breakdown. Line items look like confidence in your pricing.
Disposal and installation details close callbacks before they start. What happens to the old windows? Who patches the interior casing? Who caulks exterior trim? Who is responsible if the rough opening needs reframing? Answer all of it in the proposal. "Includes haul-off of old units, exterior caulking, and interior casing reinstallation" versus silence on those items is the difference between a signed contract and a week of follow-up calls.
