Frequently Asked Questions

  • What's the difference between pressure-treated and composite decking in Maine?

    Pressure-treated wood is more affordable and stands up well to Maine's freeze-thaw cycles, but requires periodic staining and sealing. Composite decking costs more upfront but resists moisture, rot, and fading with minimal maintenance. At C. Duffy Exteriors, we help homeowners choose based on budget, maintenance preference, and how the deck will be used year-round or seasonally.

  • How does Maine weather affect roofing material choices?

    Maine's heavy snow loads, ice dams, and temperature swings require roofing that can handle expansion, contraction, and moisture. Asphalt shingles offer reliable performance and affordability, while metal roofing excels at shedding snow and resisting ice buildup. C. Duffy Exteriors recommends materials based on your roof pitch, exposure, and whether the home is year-round or seasonal.

  • When should you replace your roof instead of repairing it?

    If your roof has widespread shingle damage, multiple leaks, or is approaching 20 years old, replacement is usually more cost-effective than ongoing repairs. A professional inspection reveals the extent of wear, decking condition, and remaining lifespan. At C. Duffy Exteriors, we provide honest assessments and help homeowners make informed decisions without pressure.

  • What siding materials work best for older Maine homes?

    Vinyl siding offers affordability and low maintenance, while LP SmartSide and Hardie board provide superior durability and a traditional wood appearance. Cedar shake delivers classic curb appeal but requires more upkeep in coastal or湿气-prone areas. C. Duffy Exteriors helps match siding to your home's style, budget, and exposure to Maine's climate.

  • How long does it take to build a custom deck?

    Most deck projects take one to three weeks depending on size, design complexity, and permit requirements. Weather delays and material delivery can extend timelines, especially during peak season. At C. Duffy Exteriors, we set clear expectations upfront and communicate any changes so homeowners know what to expect from start to finish.

  • Can you build a deck on a lakefront or coastal property?

    Yes, lakefront and coastal decks require careful attention to moisture exposure, soil conditions, and local building codes. Composite materials and proper drainage details help decks withstand salt air and seasonal flooding. C. Duffy Exteriors has experience building decks for lake homes and coastal properties across central and coastal Maine.

  • What's the biggest mistake homeowners make with siding installations?

    Neglecting proper flashing and moisture barriers leads to water infiltration, rot, and mold behind the siding. Cutting corners on installation to save money often results in costly repairs down the road. At C. Duffy Exteriors, we prioritize moisture protection and clean finishes to ensure siding performs well for decades in Maine's wet, variable climate.

  • How do you prepare your home for a roofing project?

    Clear vehicles and outdoor furniture from around the house, cover items in the attic, and expect noise and vibration during tear-off and installation. Communicate with your roofing crew about access points, pets, and any fragile landscaping. C. Duffy Exteriors reviews site logistics and safety measures before starting so homeowners feel prepared and informed.

  • Why do metal roofs shed snow better than asphalt shingles?

    Metal roofing has a smooth, slippery surface that allows snow and ice to slide off more easily, reducing the risk of ice dams and structural load. Asphalt shingles have more texture and grip, which can hold snow longer. In areas like Oakland and Bangor with heavy snowfall, metal roofs offer faster snow release and less maintenance.

  • What affects the cost of building a new deck?

    Deck size, material choice, design features like stairs or built-in seating, and site conditions all influence cost. Composite decking and complex layouts increase expenses, while pressure-treated wood and simpler designs are more budget-friendly. At C. Duffy Exteriors, we provide transparent estimates and help homeowners balance design goals with budget realities.

  • Do composite decks hold up better in Maine winters?

    Composite decking resists moisture absorption, warping, and cracking caused by freeze-thaw cycles, making it ideal for Maine's harsh winters. It won't splinter or require annual staining like wood. C. Duffy Exteriors installs composite decks designed for year-round durability, especially on homes exposed to snow, ice, and seasonal temperature swings.

  • How do you maintain a pressure-treated wood deck?

    Clean the deck annually with a mild detergent, inspect for loose fasteners or rot, and apply a quality stain or sealant every two to three years. Proper ventilation underneath and prompt debris removal prevent moisture buildup. At C. Duffy Exteriors, we build pressure-treated decks with longevity in mind and advise homeowners on simple maintenance to extend deck life.
