Bel Air is the Harford County seat and one of our most-active service areas. We're about 15 minutes from our Fallston office.
Near: Bel Air Town Center, Rockfield Park, Liriodendron Mansion neighborhoods.
We're MHIC #91686-licensed, Trex Pro Platinum, an authorized Sunspace dealer, and Azenco-certified for motorized louvered pergolas. Every Bel Air project is custom-designed, permitted, and built end-to-end by our own crews. No subcontracted middlemen.
Services we build in Bel Air
Custom decks in Bel Air
Bel Air is one of our most-active deck markets. Our Fallston shop is about 15 minutes from the Bel Air Town Center, so we handle site visits, permit pickups at the Harford County office, and inspections without adding travel to your quote. We build Trex composite decks, wood decks, and multi-level layouts across the Rockfield Park, Liriodendron, and Homestead Village neighborhoods. As a Trex Pro Platinum builder (top 1 percent nationally) and MHIC #91686 contractor, we design each Bel Air deck around your grade, sun exposure, and how you actually use the space.

"Loved working with Mark and his guys! Love our new sunroom even more! Mark was open and honest from the very first call (and never salesy). He was a great resource in helping us finalize the design and recommending a few changes we would have never thought of. After our terrible experience getting a pool two summers ago it was very refreshing to work with a company who did what they said they were going to do and were on schedule! Highly recommend CDB."
Custom pergolas in Bel Air
Bel Air pergolas need to fit both established neighborhoods and newer communities around Town Center and Rockfield Park. We plan shade around the direction of the house, available patio or deck space, and any HOA requirements before recommending wood or a motorized louvered system. Our Fallston office is about 15 minutes away. As a certified Azenco installer under MHIC #91686, we handle the Harford County permit and inspections, then build with our own crews rather than sending the project to a subcontractor.

Sunrooms in Bel Air
Bel Air sunroom projects benefit from our office being about 15 minutes away in Fallston. Homes around Town Center, Rockfield Park, and Liriodendron vary in age and construction, so we examine the foundation, roof tie-in, drainage, and electrical needs before selecting a system. As an authorized Sunspace dealer, we offer three-season and four-season options. Our own crews handle the structural and finish work, while we manage the Harford County permit and inspections under MHIC #91686.

Retractable awnings in Bel Air
Add on-demand shade to your Bel Air deck or patio with a motorized Alutech SunShield retractable awning. As an authorized Alutech dealer, we install premium Sunbrella awnings with LED-lit arms, remote operation, and optional wind and sun sensors for Bel Air homeowners, usually in a single day. Extend it when you want shade, retract it when you want full sun.
