Window Company in Lake Arrowhead, CA
Westlight Windows & Doors is a window company serving Lake Arrowhead, CA, where mountain cabins and chalets need glass and frames that can handle real winter. We replace and install windows and doors across Lake Arrowhead with products matched to the elevation, the snow, and the sun. At 5,174 feet, the wrong window fails fast – seals fog, wood rots, frames warp. The right one, properly flashed and sealed, keeps a cabin warm through January and cool in August. Call (760) 624-3669 for a free estimate on any window or door project in Lake Arrowhead.
Why Lake Arrowhead Homes Are Different
Lake Arrowhead houses sit in a climate that punishes ordinary building materials. Winter brings heavy snowfall that drifts against entry doors and buries ground-level windows for weeks. Freeze-thaw cycles work water into frame joints, where it expands and splits wood. Summer flips the problem: strong UV at elevation bakes south-facing glass and fades interiors fast. Most of the original windows in Lake Arrowhead are single-pane units in cedar-sided A-frames and mid-century cabins, and those units were never designed for what this mountain throws at them.
What that means practically: wood frames around Lake Arrowhead need rot-resistant treatment or full replacement with materials that shed moisture. Weather sealing has to be done right the first time, because a small gap that would be harmless in the valley becomes an ice dam and a condensation problem up here. And door frames carry a load most people never think about – snowdrifts lean against entryways for months, so reinforcement and proper flashing matter more than they do anywhere lower down the hill. Stainless steel hardware is another mountain-specific detail: standard hardware rusts in the moisture that lingers after snowmelt.
Cedar, Pine, and the Rim communities around Lake Arrowhead all have their own mix of original cabins and newer chalets, but the underlying problems repeat: single-pane glass, weathered wood, and doors that no longer seal. We plan every Lake Arrowhead job around those conditions, not around what works at sea level.
Our Main Lake Arrowhead Services
Most Lake Arrowhead homeowners call us for two things: replacing windows that have failed, and installing new windows or doors in a remodel or addition. Here is what each involves on the mountain.
Window Replacement in Lake Arrowhead
Replacing windows in a Lake Arrowhead cabin usually starts with pulling out single-pane units that have been fighting the weather for 40 or 50 years. We measure for dual-pane replacements with low-e coatings, which means the glass reflects heat back into the room in winter and back outside in summer. The work includes proper flashing and insulation around every opening, because that is where mountain moisture gets in. Many homeowners here pair replacement with rot repair on the surrounding frame. For the full breakdown, see Window Replacement in Lake Arrowhead.
Window Installation in Lake Arrowhead
New-construction window installation in Lake Arrowhead covers additions, remodels, and full cabin rebuilds. The job is about getting the rough opening right before the window ever goes in, then sealing it so snowmelt and wind-driven rain stay outside. We install windows from eight manufacturer lines, including impact-rated options for homeowners who want glass that handles mountain debris and heavy wind. On new work, we coordinate with the framing and flashing schedules so inspection-ready installation happens once, not twice. Details are on Window Installation in Lake Arrowhead.
Door Installation in Lake Arrowhead
Door installation around Lake Arrowhead means more than hanging a slab. Entry doors here take direct snow load in winter, so we check and reinforce the rough opening, install proper sill pans and flashings, and use hardware that resists rust from mountain moisture. A door that drags against snowdrifts or lets cold air pour in around the jamb is a door that was installed for a different climate. We install Therma-Tru entry systems among other lines, and we build the opening to stay square through freeze-thaw cycles. See Door Installation in Lake Arrowhead for the full scope.

Every customer gets a written price before any work starts, and that number does not change at the door.
