About Our Doors & Windows
Properly functioning doors and windows are essential for comfort, security, and energy efficiency — especially in the mountain climate of Big Bear Valley. Anthony Mark Lee installs, adjusts, repairs, and replaces doors and windows of all types.
In the Big Bear Valley, energy efficiency is a real concern. Drafty windows and poorly sealed doors can significantly increase heating costs during cold mountain winters. Our team assesses your existing openings, repairs or replaces worn components, and upgrades weather stripping and seals to keep cold air out and conditioned air in.
We work with interior and exterior doors of all styles — from entry doors and sliding patio doors to interior passage doors and bifold closet doors. For windows, we handle everything from single-pane replacements and broken sash repairs to full window unit replacements and installation of new openings.

Common Questions
Frequently Asked Questions — Doors & Windows
Can you fix a sticking or dragging door?
Yes. Sticking doors are common in mountain homes due to seasonal humidity changes. We diagnose the cause — swelling, hinge wear, frame movement — and make the right fix.
Do you install new entry doors?
Yes. We install pre-hung entry doors, including standard sizes and custom openings, with proper insulation, weather stripping, and hardware installation.
Can you upgrade single-pane windows to double-pane?
Yes. Upgrading to double-pane or insulated glass is one of the most impactful improvements for energy efficiency in Big Bear Valley homes.
