Churches and places of worship, schools, retail and commercial buildings, medical offices, self-storage facilities, and apartment or multi-unit properties across Maryland.
Yes, flat and low-slope systems are a core commercial service, including TPO, EPDM, and modified bitumen, plus EIFS systems (we are EIFS certified).

Yes. Scheduled maintenance and inspections catch ponding, seam separation, and flashing failures while they are still small repairs rather than a full system replacement.
Yes. We work as a contractor on Baltimore City DHCD housing rehabilitation and repair projects, and we are familiar with the documentation and scope requirements those programs carry.

Yes, fully licensed, insured, and bonded, and BBB A+ accredited. We can provide certificates of insurance for your property manager or board.
