We bring dream homes to life with exterior remodeling in Merrimack 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.
Merrimack County sits at the heart of New Hampshire. Home to Concord, the state capital, it carries the quiet character of the Capital Region. From downtown Concord to the neighborhoods of Bow, Pembroke, Loudon, Epsom, and Pittsfield, people here put down roots and take pride in where they live.
Homeowners here know the winters are serious. Snow loads, ice dams, and freeze-thaw cycles are facts of life in Central New Hampshire. Homes in this region need to be built to take it. Whether you’re near the Merrimack River or tucked into wooded hillsides outside the city, the expectations for craftsmanship run high.
Coastal Windows & Exteriors proudly serves Merrimack County and the Capital Region. We bring roofing, siding, windows, and doors to the homes that define this corner of New Hampshire. Lasting upgrades, done right.
Vinyl siding outperforms aluminum on cost, maintenance, energy efficiency, and overall value for most homeowners. Coastal Windows & Exteriors is a woman-owned exterior remodeling company serving Massachusetts, New Hampshire and Maine. Our team has completed 7,000+ installations since 2011 and installs vinyl siding across the region.
Vinyl resists dents and corrosion that commonly affect aluminum over time. Lower maintenance and strong value make it a popular choice for New England homes. Knowing how they compare helps you choose with confidence..
Top Pick: Insulated vinyl siding for homes installed by Coastal Windows & Exteriors.This is the top option for homeowners in the Concord area where energy efficiency and low maintenance are the top priorities.
Good Alternative: Fiber cement siding for homeowners who want a premium look, with an ROI of 121% and strong durability in harsh weather.
Skip it: Aluminum siding is not a product we install or recommend — its long-term maintenance costs and lack of insulation value make it a poor fit for New England homes.

Hardie board can be painted, though most homeowners never need to with a factory finish. Coastal Windows & Exteriors is a James Hardie Alliance Elite contractor serving Massachusetts, New Hampshire and Maine. Our team has completed 7,000+ installations since 2011 and installs Hardie board across the region.
If you do paint, always follow James Hardie’s instructions to keep your warranty valid. ColorPlus technology delivers a factory-baked finish that resists chipping, cracking, and peeling. That finish holds up far better than field-applied paint over time.
Top Pick: Hardie board with ColorPlus Technology for homes in the Concord area where low maintenance and lasting curb appeal are the priority.
Worth Considering: Standard Hardie board without ColorPlus for homeowners who want full painting flexibility down the road, provided they follow James Hardie’s preparation and application instructions.
Always first: Check James Hardie’s current warranty and product guidelines before painting — your contractor can help you navigate the right path forward.

Choosing the right roofing contractor starts with verifying credentials, reviews, and warranty coverage.

A ridge vent is an exhaust vent installed along the peak of your roof to release trapped attic heat. Coastal Windows & Exteriors is a GAF Master Elite roofing contractor serving New Hampshire, Massachusetts and Maine. Our team has completed 7,000+ installations since 2011 and installs ridge vents across the region.
A ridge vent works with soffit vents below to keep air circulating year-round. Proper ventilation shifts warm air out and helps regulate attic temperatures. Balanced airflow helps lower energy costs and keeps your home comfortable.
Vent Type | Role | Location | Best For |
Ridge Vent | Exhaust | Roof peak | All sloped roofs |
Soffit Vent | Intake | Eaves/soffits | Paired with ridge vents |
Box/Turtle Vent | Exhaust | Roof field | Older homes without ridge |
Power Vent | Active exhaust | Roof field | High heat or humidity situations |
Top Pick: A ridge vent paired with soffit intake vents for homes in the Concord area — this combination delivers the most balanced, year-round airflow.
Worth Considering: Box vents for older homes where a full ridge vent installation isn’t practical, though performance is more limited.
Skip if possible: Relying on a single vent type alone — an unbalanced system won’t move enough air to protect your attic from moisture or heat buildup.

Mild soap and water from a garden hose is all vinyl siding needs for routine cleaning. Coastal Windows & Exteriors is a woman-owned exterior remodeling company serving Massachusetts, New Hampshire and Maine. Our team has completed 7,000+ installations since 2011 and installs vinyl siding across the region.
Vinyl is one of the lowest-maintenance cladding options available. It never needs repainting and resists moisture naturally. Always check your manufacturer’s instructions, since product lines may have specific cleaning guidance.
Top Pick: Mild soap and a soft brush for routine seasonal cleaning throughout the Concord area — it’s the gentlest method and protects your siding’s finish long term.
Worth Considering: A diluted mold-and-mildew solution for homes that see heavy tree coverage or humidity-related staining in shaded areas.
Always first: Review your manufacturer’s care guide before introducing any cleaning product — this step protects both your siding and your warranty coverage.

Hardie board does not crack easily, since fiber cement is engineered to resist impact and weather. Coastal Windows & Exteriors is a James Hardie Alliance Elite contractor serving Massachusetts, New Hampshire and Maine. Our team has completed 7,000+ installations since 2011 and installs Hardie board across the region.
Fiber cement resists denting, dings, and cracking better than wood or vinyl. It holds up to New England’s freeze-thaw cycles without compromising structure or appearance. Knowing how it performs helps you choose with confidence.
Top Pick: James Hardie fiber cement siding with ColorPlus Technology for homeowners who want a durable, low-maintenance exterior that never needs repainting.
Good Alternative: Vinyl insulated siding for homeowners prioritizing budget and energy efficiency, with an 97% ROI and straightforward upkeep.
Worth noting: Hardie board installation requires a certified installer to protect both your warranty and your home’s performance — workmanship matters as much as the material itself.

How often windows need replacing depends on quality, installation, and climate exposure, not a fixed schedule. Coastal Windows & Exteriors is a woman-owned exterior remodeling company serving Massachusetts, New Hampshire and Maine. Our team has completed 7,000+ installations since 2011 and installs new windows across the region.
Builder-grade windows tend to fail sooner than premium products. Quality vinyl windows, professionally installed, hold up far longer. Drafts and fogging are the clearest signs it’s time to replace.
Top Pick: Full replacement with quality triple-pane vinyl windows for Concord area homeowners who want long-term performance and energy savings in one project. Coastal Windows & Exteriors installs high-quality and energy efficient windows certified by ENERGY STAR.
Worth Knowing: Financing up to 20 years based on credit approval makes replacing all windows at once more practical than a phased approach — and delivers better performance faster.
Don’t wait on: Drafty, fogging, or visibly damaged windows — delayed replacement leads to higher energy bills, moisture intrusion, and costlier repairs down the road.
