- Window prices are per unit installed for insert replacements into sound frames; full-frame replacements and rot repair price above the bands.
- Siding tiers are whole-house vinyl figures anchored to the metro's $18,200 average project; fiber cement and wood run well above the vinyl bands.
- Historic-district window work is modeled at +20% (sources put it at 15–30%) for commission-approved styles and materials.
- Mass Save rebates of $150–$250 per qualifying window are not netted into the totals — treat them as an offset at the end.
- Gutter guards span $1–$20+ per foot nationally by type; the calculator bands the installed mid-market ($3–$12) between snap-in screens and premium micro-mesh systems.

What drives the price
Windows: the tier is the price
The spread from a $400 basic vinyl unit to a $4,000 triple-pane wood window is the biggest lever on the whole job — count × tier before anything else. In South Shore's historic districts, commission approval narrows what you're allowed to install and adds 15–30% for compliant styles and sightlines.
Siding: size, stories, and what's underneath
Whole-house pricing scales with wall area and complexity — gables, trim detail, and second-story staging all add labor. The quote-versus-final risk is what's found under the old siding: rotted sheathing or old wiring surprises are why contractors who probe before quoting are worth the wait.
Gutters: seamless earns its premium here
The $8–$14 per foot for seamless versus $4–$9 sectional buys continuous runs with joints only at corners. In South Shore's freeze-thaw winters — where ice dams stress every seam — fewer joints means fewer leaks, which is why most local installers quote seamless by default.
Efficiency programs change the math
Mass Save's $150–$250 per-window rebate effectively drops a tier's price, and efficiency-driven projects sometimes unlock favorable financing too. Before comparing window bids in Massachusetts, ask each installer to show the rebate as its own line — an honest quote separates the discount from the price.

- How much does window replacement cost in South Shore?
- Installed per-window prices in South Shore run $400–$1,100 for basic vinyl (with $600–$800 typical), $800–$1,500 for premium vinyl or fiberglass, and $1,500–$4,000 for wood or triple-pane units. A 10-window vinyl-replacement job comes to roughly $21,900 in New England cost-vs-value data — and recoups about 76% of that at resale, among the better returns of any exterior project.
- Are there rebates for new windows in Massachusetts?
- Yes — Mass Save offers $150–$250 per window for qualifying ENERGY STAR replacements, which on a 10-window job is a $1,500–$2,500 offset. The catch is eligibility rules (typically replacing single-pane units, with program terms that change year to year), so confirm the current requirements before signing and make sure your installer handles the paperwork.
- How much does new siding cost in South Shore?
- Whole-house vinyl siding in South Shore runs $10,700–$30,600 depending on house size, with the metro average around $18,200. Figure $10,700–$14,000 for a small ranch or cape, $16,000–$20,000 for a two-story colonial, and $24,000–$30,600 for a large home. Fiber cement and wood clapboard cost meaningfully more — those quotes deserve their own comparison.
- How much do seamless gutters cost in South Shore?
- Seamless aluminum runs $8–$14 per linear foot installed against $4–$9 for sectional, so a typical 150-foot colonial comes to $1,200–$2,100 seamless or $600–$1,350 sectional. Seamless is formed on-site in continuous runs with joints only at corners — fewer places to leak, which matters over New England winters.
- Are gutter guards worth it?
- Mid-market installed guards run $3–$12 per linear foot — $450–$1,800 on a 150-foot home — while professional gutter cleaning in South Shore runs $126–$219 per visit, typically twice a year. Under heavy tree cover the guards can pay for themselves in a few seasons; on an open lot with little debris, the cleaning schedule is cheap enough that guards are more convenience than economics.
