Common Questions

Do I need impact rated glass on my doors?

If you’re within two miles of the sound or Atlantic, local code and many insurers require it. Even inland, it adds security and longevity.

How long does installation take?

Most replacements finish in a single day, including removal, prep, installation and cleanup.

Do I need a permit to replace my front door in New Hanover County?

Most like-for-like door swaps don’t require permits, but if you’re enlarging the opening, adding sidelights or installing impact-rated glass, check with the City of Wilmington’s permitting office. We handle permits for you to ensure full compliance.

Will my new door help reduce my energy bills?

Yes. An ENERGY STAR®-qualified door with an insulated foam core and thermally broken threshold can lower heat transfer by up to 30%, cutting your cooling load during Wilmington’s hot, humid summers. Combine a new door package with the Best Most Energy Efficient Windows in Wilmington NC and you're sure to have solid savings!

Why Choose Coastal Grade Doors?

Durability Against Salty Air

Standard doors warp and corrode near the coast. Our fiberglass and galvanized steel cores resist rust, rot and swelling—even within two miles of the Atlantic.

Hurricane and Impact Rated Doors

All door systems meet or exceed North Carolina’s 130 mph wind-uplift requirements. Multi-point locking, reinforced frames and impact-rated glass help your home stand up to tropical storms.

Energy Star Rated Doors

Wilmington’s humid summers and mild winters demand year-round comfort. Our ENERGY STAR®-qualified doors feature insulated foam cores and thermally broken thresholds, cutting heat gain and lowering your electric bills.

High ROI

Doors provide your home with the highest return on investment for a home improvement project. Improve curb appeal and total value with a single change.

Bringing the Outdoors In: A Wilmington Sliding Door Transformation

After we installed a new Timbertech deck and patio for our clients their master bedroom still felt boxed in by a single small window. We removed the old opening, widened the wall, and installed a large, energy-efficient sliding glass door. Instantly, the room flooded with natural light and opened directly onto their backyard oasis.This upgrade does more than brighten the space—it creates seamless indoor-outdoor flow, perfect for morning coffee or evening relaxation, and boosts home value in our competitive coastal market. From structural permitting to marine-grade sealing and precise trim work, we handle every step to add real, lasting value to your home.

Whether you need a simple slider replacement or a full-wall conversion like this, our team in Wilmington, NC, is ready to transform your space—and your lifestyle.

My husband and I met with Pat Jewell and he was such a pleasure to work with. Very knowledgeable and kind. We felt comfortable with this company.
We are very pleased with the work that Capitol Improvements did and we would highly recommend and use them again in the future.

Seth and install team were organized and project went smoothly. Entire team was responsive and kept in touch throughout the process.
They replaced my roof including skylights in April 2023 and I am very satisfied. Melinda as my first contact was very professional and got me on the schedule quickly.
It was easy to work with Pat to get a quote. We did both a roof on our house and our shed, we also had new gutters put on our den. The crew was very hardworking and efficient.
