Sandown, NH’s Trusted Exterior Remodelers

Your home deserves more than just a fresh coat of paint or a quick fix. It deserves solutions built for New Hampshire weather and a team that shows up, follows through, and treats your home like their own.

That’s exactly what we bring to the table at Capital Construction. Since 2005, our exterior remodeling company has helped homeowners across Sandown and southern New Hampshire tackle a range of projects, including roofing, siding, decks, windows, and more. We’re not here for shortcuts. We’re here for superior craftsmanship, consistency, and customer service that keeps people coming back.

Built for Sandown’s Climate, Designed for Your Home

Capital Construction has beautified homes off Fremont Road, around Angle Pond, and throughout Rockingham County. We know what your home is up against (from nor’easters in the winter to blazing humidity in July), and we know how to remodel for it.

Whether you’re dealing with an aging roof, dated siding, or a backyard that’s ready for a deck, we’re here to make the exterior remodeling process a breeze. 

Roof Replacement Services Fit for New England 

Roofing in Sandown needs to be more than just watertight; it must also withstand high winds, ice dams, UV exposure, and snow loads. That’s why Capital Construction offers premium roof replacement services using:

• GAF architectural asphalt shingles for strong curb appeal and unbeatable warranty coverage

• Evergreen Slate for homes with historic character or natural stone finishes

• Carlisle EPDM for flat or low-slope roofs that need watertight performance

We don’t do half-measures or patch jobs. Every roof we install is built to last, and we’ll walk you through every detail, from underlayment to ridge caps.

Brighten Your Home with Skylights

Let more natural light into your home with Velux skylights, professionally installed with proper flashing to guard against leaks and moisture issues. Perfect for bathrooms, stairwells, and second-story rooms that could use a little sunlight.

Siding That Protects and Elevates

The right siding can do more than freshen up your home’s appearance. It can improve energy efficiency, eliminate upkeep, and protect against New England’s wild weather swings.

Capital Construction proudly installs:

• James Hardie fiber cement siding for bold style and serious weather resistance

• Alside vinyl siding for a cost-effective upgrade with minimal maintenance needs

You’ll be able to choose from dozens of styles and colors. Our team is here to help you find the perfect fit for your Cape, Colonial, or ranch-style home.

Custom Decks That Fit the Way You Live

If you're spending your evenings on the porch or hosting friends on weekends, a new deck can make all the difference. We design and build custom decks with Trex composite decking, so you can enjoy the outdoors without worrying about splinters, stains, or sanding.

• Fully customizable layouts

• Optional lighting, stairs, and built-in benches

• Renderings available before we build

Your backyard should feel like an extension of your home. We’ll make sure it does.

Efficient Replacement Windows & Secure Doors

• Alside and Weather Master replacement windows, including double-hung, casement, bay, and bow styles

• ProVia doors for front entries, side doors, and patios, built for performance and style

All window and door installations come with energy efficiency ratings, secure locking systems, and custom sizing for a perfect fit.
