We bring dream homes to life with exterior remodeling in Strafford County, NH: Energy efficient roofing, replacement windows, vinyl and James Hardie siding, and entry doors with an empathetic and educational approach to transforming your home.
Strafford County occupies a distinct corner of New Hampshire. It sits far enough inland to catch the full force of a NH winter, yet close enough to the coast to feel the pull of the Seacoast Region. Dover, Rochester, and Somersworth form the urban core, while Durham, Barrington, and Farmington bring a quieter, small-town character to the county.
Homes here span the full range of New England architecture. Colonial capes sit alongside newer construction, ranch homes, and everything in between. What they share is exposure to freeze-thaw cycles, heavy snow loads, and seasonal moisture that test every exterior surface over time.
Coastal Windows & Exteriors proudly serves Strafford County homeowners across the Inland Seacoast. We install roofing, siding, windows, and doors built to last through whatever this region brings.
Choosing the right roofing contractor starts with verifying certification, insurance, local experience, and an honest written estimate.
A GAF Master Elite certified roofing contractor has met the highest standards in the industry. This status is earned by only the top 2% of roofing professionals in North America. For homeowners throughout Strafford County, knowing what to look for protects you from hiring someone underqualified for a project that averages $35,701.
What Homeowners in the Inland Seacoast Region Need to Know
Choosing the Right Contractor for Your Strafford Home
Top Pick: A GAF Master Elite certified roofing contractor for any full replacement project in Southern NH — certification means better warranties, stricter training, and higher accountability. Contact Coastal Windows & Exteriors for a free estimate!
Worth confirming: That your contractor pulls the required permits, provides a written scope of work, and can walk you through every layer of the roofing system before a single shingle goes down.
Skip entirely: Any contractor who can’t provide proof of insurance, avoids permit discussions, or pressures you to decide on the spot.

The most common siding types in Strafford County are vinyl, fiber cement, wood, and engineered wood — and each one looks, feels, and performs differently.
Knowing your siding type helps you understand what maintenance it needs, whether it’s the best siding for New England conditions, and when it might be time to replace it.
Top Pick: Vinyl siding with a foam-back insulated option for homes in the Seacoast Region — it delivers the lowest maintenance, strongest energy performance, and reliable long-term durability.
Good upgrade: Fiber cement siding for homeowners who want a premium exterior with a 144% ROI and strong resistance to impact, moisture, and fire. Coastal Windows & Exteriors is a James Hardie Preferred Contractor, offering you plenty of perks and exceptional craftsmanship.

James Hardie’s Hardie board is a brand of fiber cement siding. It’s the most widely recognized and installed in the industry, especially here in New Hampshire.
All Hardie board is fiber cement siding, but not all fiber cement siding is Hardie board. James Hardie is the manufacturer behind HardiePlank®, HardieShingle®, and HardiePanel®.
Product | Profile | Best For | ColorPlus Available |
HardiePlank® | Horizontal lap | Most home styles | Yes |
HardieShingle® | Cedar shake look | Coastal and cottage styles | Yes |
HardiePanel® | Vertical panel | Contemporary and farmhouse styles | Yes |
Generic fiber cement | Varies | Budget-driven installs | Varies by brand |
Top Pick: HardiePlank® with ColorPlus Technology for most homes — it’s the most versatile profile, never needs repainting, and carries strong warranty protection when installed by a certified contractor. Coastal Windows & Exteriors is a James Hardie Preferred contractor, bringing you the best selection of Hardie board and quality installation! Contact us for a free estimate.
Worth considering: HardieShingle® for homes with a traditional or coastal aesthetic that want a premium cedar look without the cedar maintenance demands.
Important distinction: Not all fiber cement is created equal. James Hardie’s products are engineered for specific climate zones — choosing a James Hardie Elite Preferred contractor ensures you get the right product for your region.

Savings, comfort, and 40%+ efficiency improvement make them the strongest long-term choice. Coastal Windows & Exteriors is one of the top window companies in Southern NH. Call us for a free estimate!
Worth knowing: Financing up to 20 years based on credit approval makes full window replacement practical without waiting, so you start saving sooner rather than later.
Don’t delay on: Drafty or failing windows — every month you wait is money lost to heating and cooling a leaky envelope that good windows would seal.

Quality double-pane windows professionally installed can last 25 years or more. However, builder-grade units may need replacing within 10 years.
The gap between a builder-grade double-pane window and a high-quality professionally installed unit is enormous . This is true for both lifespan and performance. Homeowners across Strafford County are often surprised to find their double-pane windows have already lost their seal and are costing them money every month.
Window Type | Expected Lifespan | U-Value | Replacement Signal |
Builder-grade double-pane | Up to 10 years | 0.30–0.45 | Fogging, drafts, early failure |
Quality double-pane (pro-installed) | 25+ years | 0.30–0.45 | End of rated service life |
Triple-pane (pro-installed) | 25+ years | 0.20–0.30 | Rarely — outperforms double-pane significantly |
Top Pick: High-quality triple-pane windows professionally installed for homes in the Seacoast Region replacing builder-grade or aging double-pane units — better performance, longer lifespan, and immediate energy savings. Contact Coastal Windows & Exteriors for a free estimate and energy efficient windows for your home.
Worth knowing: Financing up to 20 years based on credit approval makes replacing all windows at once practical — and lets you start capturing energy savings right away.
Don’t wait on: Fogged glass, frames that won’t seal fully, or rising heating bills — these are signs your windows have already stopped performing.

If your sliding patio door is sticking, drafty, or hard to operate, the right move is a professional assessment. We don’t recommend a DIY adjustment.
A sliding glass door that needs frequent adjusting is wearing out, losing its seal, or was never installed correctly in the first place. Replacement is a better consideration than repeated adjustments.
Top Pick: A professional door assessment for any sliding patio door showing recurring operation problems in the Seacoast Region — the diagnosis is free, and the answer is usually clear. Contact Coastal Windows & Exteriors for a free estimate!
Worth considering: If your sliding door is more than 15 years old or has visible gaps, ENERGY STAR certified replacement is a stronger investment than ongoing repairs.
Skip entirely: DIY roller adjustment, track shimming, or frame recaulking as a substitute for proper professional evaluation. These fixes rarely address the underlying issue and can void manufacturer warranties.
