Marine-Grade Sealing. Precision Framing. No Drafts.
South Bay homes face a corrosive marine environment that degrades improperly sealed door and window openings. Salt air infiltration, moisture intrusion, and thermal loss are all consequences of substandard installation. Paragon frames and installs high-end door and window systems with marine-grade sealing compounds and proper weatherproofing — the kind that lasts in Hermosa Beach, Manhattan Beach, and Palos Verdes.
