How much does window replacement cost in South Portland?

Installed per-window prices in South Portland 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 Maine?

Often. In Massachusetts, 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; Rhode Island Energy pays $75 per ENERGY STAR triple-pane window replacing single-pane after a home energy assessment; Energize CT, NHSaves, Efficiency Maine and Efficiency Vermont published no per-window rebate for 2026 and fold windows into their weatherization programs. 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 Portland?

Whole-house vinyl siding in South Portland 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 Portland?

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 Portland 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.

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.
Efficiency-program window rebates (Mass Save pays $150–$250 per qualifying window in Massachusetts; the other New England states' programs vary) 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.

Ranges are built from published New England contractor pricing and regional cost indices, scaled to Maine (×0.90 on the Greater Boston baseline that the written figures on this page quote), last reviewed 2026-11.

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 Portland'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 Portland'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

A per-window rebate ($150–$250 from Mass Save in Massachusetts, smaller amounts from the other states' efficiency programs) effectively drops a tier's price, and efficiency-driven projects sometimes unlock favorable financing too. Before comparing window bids in Maine, ask each installer to show the rebate as its own line. An honest quote separates the discount from the price.
