Entry, Patio & French Door Installation in Sonoma
Apex Line Construction installs and replaces entry doors, patio doors, French doors, and sliding glass doors throughout Sonoma with correct sill pan flashing, weather-resistant barriers, and insulation engineered for lasting performance. We work with Therma-Tru fiberglass entry doors, Simpson wood doors, and Milgard and Andersen patio doors — all selected for durability and energy efficiency.
Bay Area marine influence means fog, salt air, and moisture cycling — material selection and flashing must resist prolonged humidity and coastal exposure. A poorly flashed door leaks air and water, driving up energy bills and causing hidden moisture damage. We prepare the rough opening, install sill pan flashing, shim doors plumb and square, insulate and air seal, and finish with interior and exterior trim so your Sonoma door is weather-tight and smooth-operating for years.
Homeowners searching for door installation near Sonoma want a contractor who pulls permits where required, passes inspections, and warranties the installation — not a big-box measure-and-drop service. Apex Line handles the entire process with one accountable crew.
