A gutter proposal that specifies material gauge, profile style, downspout placement, and drainage plan wins over the generic "new gutters — $2,500" estimate. Here's what to include so the client understands they're getting a system, not just aluminum hung on their fascia.
Type of work: new installation, replacement, repair, or gutter guard addition. Total linear feet, number of downspouts, property type and stories. Note condition of existing gutters and fascia — replacement may require fascia repair or replacement that needs to be quoted separately.
Gutter profile: K-style (most common residential) or half-round. Material: aluminum (0.027" or 0.032" gauge), copper, steel, or vinyl. Color selection. Seamless vs sectional. Downspout size (2x3" or 3x4") and material. Hangers: hidden vs exposed, spacing (every 24" or 32"). End caps, miters, outlet tubes.
Where each downspout will be located and why (mark on a simple diagram if possible). Downspout extensions or splash blocks. Tie-in to underground drainage if applicable. Slope direction (gutters should slope 1/4" per 10 feet toward downspouts). This shows you're thinking about water management, not just hanging gutters.
If offered, specify type: micro-mesh, foam, brush, reverse curve, or screen. Brand and model. Warranty coverage. Cost per linear foot as an add-on. Be honest about limitations — no guard is 100% maintenance-free. This is a high-margin upsell that clients increasingly expect to see quoted.
Line items: gutters (per linear foot by material/gauge), downspouts (each), corners/miters (each), end caps, hangers, gutter guards (per linear foot if applicable), old gutter removal, fascia repair (per linear foot if needed). Show total.
Material warranty (aluminum: 20+ years, copper: lifetime). Seam warranty on seamless gutters. Workmanship warranty from your company (typically 3-5 years). Recommended maintenance: clean twice per year (spring and fall) or as needed without guards.
