Sunroom Builders in Charlotte, NC Since 1995

David Canupp started Express Sunrooms of the Carolinas in 1995 and still runs it from our office on Pleasant Oaks Circle in northwest Charlotte. For 30 years we have done one kind of work: rooms that connect a house to the outdoors. That focus is why we handle the design, the Mecklenburg County permit, the build and the final inspection ourselves, with our own crews.

We are an authorized dealer for TEMO sunroom systems and Sunspace porch systems, and we build every room to the current North Carolina Residential Code.

Patio Enclosures in Charlotte, NC: Screened, Glass and Four-Season

A patio enclosure turns the porch, patio or deck you already have into a room you can actually use. Because it sits on an existing footprint, it is usually faster and less expensive than a new addition. We build three types of Charlotte patio enclosures:

– Screened enclosures keep out mosquitoes from April through October and let the breeze through.
– Glass enclosures add light and block wind, rain and spring pollen, which Charlotte gets more of than almost any city in the country.
– Four-season rooms are insulated, tied into your HVAC and usable in July heat and January cold.

Sunroom Additions

Three-season and four-season rooms, glass enclosures and patio-to-sunroom conversions, built on your existing slab or a new foundation.

Screened Porches

Custom screened-in porches and porch-to-screen conversions. Fine-mesh screens that keep Carolina mosquitoes out and the breeze in.

Pool Enclosures

Aluminum screen cages that keep leaves and bugs out of the pool and cut down on cleaning through the long Charlotte swim season.

Retractable Screens

Motorized screens for porches, patios and garages. Shade and privacy at the push of a button, out of sight when you do not need them.

Retractable Awnings

Motorized and manual patio awnings in dozens of fabrics. Instant shade for west-facing decks and UV protection for your furniture.

Express Porch Panels

Our own clear vinyl panel system that turns an open porch into a three-season room. Panels slide open in spring and close against wind, rain and pollen.

Louvered Patio Covers

Motorized louvers that open for sun and close for rain, so the patio works in a summer thunderstorm and on a clear October afternoon.

Patio Covers

Fixed and insulated patio covers that shade the patio and protect the doors and windows behind it. A good first step before a full enclosure.

Why Choose Us

Why Charlotte Homeowners Choose Express Sunrooms

We are a family business, not a franchise call center. When you call, you reach David and the crew who will actually build your room. Here is what that means in practice.

Local Since 1995

Thirty years of sunrooms and porches in the Charlotte area, from Myers Park bungalows to new construction in Ballantyne and Fort Mill. We know which HOAs need drawings and which inspectors want to see what.

Permits and Inspections Handled

Every enclosed addition in Mecklenburg County needs a building permit. We prepare the drawings, pull the permit and schedule the inspections, so the room is legal, insurable and adds to your appraised square footage.

Built for Carolina Weather

Thermal-break aluminum framing, insulated Low-E glass and screens rated for our summer storms. Materials are chosen for 90°F humidity and 30°F winter nights, not a catalog photo.

How We Help

How Our Sunroom Process Works

Four steps, one point of contact, no surprises on the invoice. Most projects go from first visit to finished room in a few weeks once the permit is approved.

On-Site Consultation and Design

We measure the space, look at how your roofline and doors work with it, and give you a written estimate. Or start with the cost calculator first.

Permits and Engineering

We prepare the drawings and pull the permit with Mecklenburg County or your local county office. Engineering is included where the county requires it.

Construction

Our own crew builds the room. Foundation, framing, glass or screen, roof, electrical and trim. Usually one crew from start to finish.

Final Inspection and Walkthrough

The county signs off, then we walk the room with you, show you how the panels, screens or motors work, and hand over the paperwork.

 Trustindex verifies that the original source of the review is Google. Great to work with. Express Sunrooms of Charlotte seem to care about us as the customer. Very responsible and reasonable. Perform high quality results and willing to take on smaller jobs like putting a metal roof on our over-sized shed. Glad we found Express at the Charlotte/Concord Home show. Will continue to work with them in the future. Super plus all the way!

 Trustindex verifies that the original source of the review is Google. David and his crew did an awesome job! They gave me the best price out of many  estimates. Put me on the schedule quicker than any other company could! Not because they didn't have the same workload....but because his guys actually work hard and get the job done quickly!  Even the 95 degree heat didn't slow them down! My fence was made in The USA which was the icing on the cake for me! A great crew of Southern hospitality! Thanks again! :)

Frequently Asked Questions

The questions we hear most from Charlotte homeowners before they start.

How much does a sunroom cost in Charlotte, NC?

In the Charlotte area, a screened porch is the least expensive option, a three-season room sits in the middle, and a fully insulated four-season room costs the most because it adds conditioned square footage. Size, foundation and glass drive the price more than anything else. See real ranges in our pricing guide or get a number for your space in the cost calculator.In the Charlotte area, a screened porch is the least expensive option, a three-season room sits in the middle, and a fully insulated four-season room costs the most because it adds conditioned square footage.

Do I need a permit for a sunroom or patio enclosure in Mecklenburg County?

Yes. Mecklenburg County Code Enforcement requires a building permit for any enclosed addition, including sunrooms, screened porches with a roof, and glass patio enclosures. We prepare the drawings, pull the permit and schedule the inspections as part of every project. Read more about permits.

What is the difference between a three-season and a four-season sunroom?

A three-season room is not insulated or heated, so it is comfortable in spring, fall and mild summer days. A four-season room has insulated glass, thermal-break framing and heating and cooling, so it is usable in Charlotte’s 90-degree July afternoons and 30-degree January nights. The comparison table above shows the full breakdown.A three-season room is not insulated or heated, so it is comfortable in spring, fall and mild summer days.

The comparison table above shows the full breakdown.

Can you enclose my existing porch or deck?

Usually, yes. A covered porch can often be enclosed with screens, glass or our Express Porch Panels without rebuilding it. An open deck usually needs a roof added first, and we check that the footings can carry the extra weight. See how a deck-to-sunroom conversion works.Usually, yes.

How long does it take to build a sunroom?

Once the permit is approved, most Charlotte-area sunrooms and screened porches are built in a few weeks. Permit review time varies by county. A four-season room with a new foundation takes longer than a screened enclosure on an existing slab. We give you a schedule with the estimate.

Does a sunroom increase the value of a home?

A permitted four-season room adds conditioned square footage, which appraisers count. Screened porches and three-season rooms add usable space and are consistently among the most requested outdoor features in the Charlotte market. The permit matters: unpermitted additions can hurt a sale. Read more on sunrooms and home value.A permitted four-season room adds conditioned square footage, which appraisers count.
