We have been building for High Desert and mountain communities since 2015.
Wrightwood gets a full mountain winter, and a room that works in January needs real insulation, proper glazing, and a heating system designed for sub-freezing nights - not a screen porch with upgraded panels. Our all season rooms are engineered for Wrightwood's specific snow loads, freeze-thaw cycles, and the elevated UV intensity that comes with being at 6,000 feet - so the room actually gets used year-round instead of sitting empty from November through March.
Many Wrightwood homeowners bought their property for the mountain views and the outdoor feeling, and a four season sunroom is the way to enjoy both without being at the mercy of the weather. Insulated walls, low-emissivity glazing, and a climate system that works across the full elevation temperature range let you sit in the light and look at the pines on days when you would otherwise stay inside.
Most Wrightwood homes are wood-frame cabins and mountain lodge-style houses with distinct rooflines and exterior character. A custom sunroom built for this setting is designed to match the existing architecture rather than clash with it - the right pitch, the right materials, and a footprint that makes sense for a hillside or terraced lot rather than a flat valley parcel.
A significant share of Wrightwood homes were built as weekend cabins in the 1950s through 1980s, and some have had additions put on over the decades that were not built to current code or mountain-climate standards. Remodeling an existing porch or enclosure - resealing, re-glazing, adding insulation, upgrading the roof-to-wall connection - often delivers a dramatically better result than continuing to patch a structure that was never right for this elevation.
Wrightwood homes often have a covered deck or concrete pad that is exposed to snow, pine debris, and the intense UV that comes with mountain elevation. Enclosing that space with a properly engineered structure converts it into a room that works through ski season and summer, extending the comfortable living area without breaking into the original cabin footprint.
Wood decks are common on Wrightwood properties, but at 6,000 feet the UV breaks down deck finishes faster than at lower elevations, and snow weight stresses the structure every winter. Converting an existing deck into an enclosed sunroom puts a roof over that investment, protects the underlying structure from snow and UV, and turns what is often an underused seasonal space into a room that earns its keep all year.
Wrightwood sits at about 6,000 feet in the San Gabriel Mountains - significantly higher than the High Desert communities of Hesperia or Victorville, and with a fundamentally different climate. The community averages around 60 inches of snowfall per year, and the rooflines, framing connections, and glazing systems used in a valley sunroom are not rated for that kind of load. A contractor who does not engineer for snow weight, ice dam formation, and the structural stresses of repeated freeze-thaw cycles is building something that will fail - potentially within a few seasons. Rooflines on Wrightwood sunrooms need to be pitched and framed specifically to shed snow rather than hold it, and the glazing must be insulated to prevent the heat loss that turns melting snow into damaging ice at the eaves.
The housing stock in Wrightwood adds another layer of complexity. A large share of homes here are wood-frame cabins and mountain lodge-style structures built between the 1950s and 1980s - some as primary residences, many as vacation properties that have seen decades of deferred maintenance. Connecting a new room to an older wood-frame structure requires understanding how the existing building has moved and settled, where rot or moisture damage may have occurred over the years, and how to create a weathertight seal at the junction point. Hillside lots add drainage considerations that flat valley lots simply do not have, and the elevated UV intensity at this altitude - roughly 20 to 25 percent stronger than at sea level - means exterior materials and finishes need to be selected for mountain performance, not coastal California conditions.
Our crew works in Wrightwood and we pull permits through San Bernardino County Land Use Services for every project here - Wrightwood is unincorporated, so there is no city building department, and the county process includes snow load and fire safety reviews that valley permits do not have. We build the Highway 2 drive time and the mountain logistics into every Wrightwood project schedule, and we plan around seasonal road conditions on the Angeles Crest Highway so that material deliveries and crew arrivals are not held up by weather or closures.
Wrightwood is a small, tight-knit mountain community centered around the village on Big Pines Highway and anchored by Mountain High Ski Resort, which draws visitors from the Los Angeles area every winter and gives the town its seasonal rhythm. We work on homes throughout the area - from the village core to the neighborhoods up in the pines and out toward the Big Pines and Table Mountain area to the east. Many properties sit on sloped or terraced lots, and we factor that hillside access into how we plan material staging and crew movement from the first day of the job.
We also regularly serve the neighboring High Desert community of Phelan down on the plateau, and the Inland Empire city of Fontana at the base of the Cajon Pass - so our service area covers the full elevation range from the valley floor to the San Gabriel Mountain communities.
Tell us about your home - whether it is a primary residence or a cabin, roughly how large a room you are thinking about, and what you want to use it for. We reply to every new inquiry within 1 business day and schedule a free site visit so we can see the property in person before giving you any numbers.
We drive up and walk the property - look at the existing structure, assess the lot slope and drainage, and identify any issues with the existing foundation or framing that would affect the new room. The written estimate we provide after this visit reflects your actual site conditions, including the mountain-specific engineering requirements. No obligation and no charge for the estimate.
We submit the permit application and drawings to San Bernardino County on your behalf. The county review includes snow load and fire safety checks specific to this elevation and fire hazard zone. Plan review typically takes two to four weeks - we handle the back-and-forth with the county and keep you updated so you are not chasing it down yourself.
Active construction on most Wrightwood projects takes three to five weeks - foundation and any slope grading first, then framing, glazing, insulation, and any climate control or electrical work. We schedule county inspections as the work progresses and do a full walkthrough with you before the job is closed out. If you are not in town full-time, we can coordinate the walkthrough around your schedule.
We build mountain-rated sunrooms and all season rooms throughout Wrightwood and the surrounding San Gabriel Mountains communities. Free estimates, no obligation.
(760) 392-8157Wrightwood is an unincorporated mountain community in San Bernardino County sitting at about 6,000 feet elevation in the San Gabriel Mountains, with a permanent population of roughly 4,500 people. The community is centered on the village along Big Pines Highway and is closely tied to Mountain High Ski Resort, which draws Los Angeles-area visitors every winter and gives the town much of its seasonal economy. Housing is a mix of full-time primary residences and part-time vacation cabins, many of them wood-frame structures built in a mountain lodge or rustic cabin style between the 1950s and 1980s. Lots are often sloped or terraced, with mature pine and cedar trees growing close to structures - a feature that adds to the mountain character but also means gutters fill with pine needles and branch falls are a recurring maintenance concern.
Wrightwood sits just off State Route 2 (the Angeles Crest Highway), which is the main route in and out of town and is sometimes closed in winter due to snow or rockslides. The community extends east toward the Big Pines and Table Mountain area, which locals use as a reference point for the eastern end of the Wrightwood corridor. Property values here run well above the San Bernardino County median, and homeowners tend to invest in maintaining and protecting structures that represent real equity. The nearby High Desert community of Phelan sits just north on the plateau below the mountains, sharing some of the same San Bernardino County permitting process and High Desert building conditions, though at a lower elevation and with a different housing stock.
