Ameristar Construction in Muscoy, CA | Hampton Contractors
We provide independent Ameristar service in San Bernardino and across Muscoy, from replacement units to weather sealing and sash repairs. The thing that separates our Ameristar work here from work in any neighboring city: Muscoy is an unincorporated San Bernardino County island, so every installation we do runs on county permit and inspection rules, not city of San Bernardino rules. If you’ve got Ameristar windows that whistle in the wind or a fogged double-hung that leaks at the corners, call us at (833) 467-4075 and we’ll tell you straight whether it’s a repair or a replacement.
Why Muscoy Residents Choose Us for Ameristar Service
We know these products from the rough opening out. Ameristar by Ply Gem sold a lot of builder-line windows and entry doors through Inland Empire supply yards in the 1990s and 2000s, and a big share of them ended up in Muscoy’s older ranch houses and owner-built homes. Brent Calloway, our owner, started his construction career at Victor Valley College and has spent over two decades working the High Desert and Inland Empire housing stock that dominates Muscoy, where a window rough opening is rarely square and the framing rarely matches the spec sheet. We measure every opening, correct the framing and flashing first, then install the Ameristar product the way it needs to go in here, not the way a showroom diagram assumes. We source Ameristar sales & service parts that fit the actual series you’ve got, and we’re honest about when a unit has one more season in it versus when it’s done.

Common Ameristar Construction Problems We Solve in Muscoy
- Failed perimeter seals and lifted flashing on Ameristar builder-line vinyl windows. Muscoy sees real winter storm runoff and intense summer UV. When an older roof or stucco job leaves the window flange exposed, water creeps behind the nail fin and rots the sill before you ever see a stain on the drywall. We find it early, rebuild the sill pan, and reflash the opening properly.
- Melted or chalked weatherstripping and gasket shrink. Inland summer heat bakes Ameristar gaskets and sash seals until the windows whistle in Santa Ana winds and sweat on the inside of the glass. Replacing the weatherstrip and resealing the frame restores them cheaper than new units, and we do that work regularly in Muscoy’s older housing stock.
- Sticking sliders and cracked sash corners on Ameristar sliders. Large owner-built openings that were never shimmed correctly rack the frame as the house settles. The sash drags or the vinyl corner cracks. We reset the frame and re-shim before we condemn the unit, because a lot of these windows are worth saving.
- Door-slab delamination and failed hinges on fiberglass entry doors. Full western sun exposure peels the finish and lets water into the slab edges. The weight of a heavy slab overwhelms undersized hinges. We refinish, re-hinge, and re-seal the opening rather than selling a whole new unit when the slab is still sound.
- Fogged double-hung glass on older Ameristar units. Failed sealed units are the most common call we get from Muscoy. The glass is often replaceable, but when the frame itself is cracked or the nail fin has rotted into the sheathing, we’ll tell you honestly that a full replacement is the smarter spend than another repair.
Ameristar Service in Muscoy: What Local Conditions Mean for Your Equipment
Muscoy’s county-island status changes how Ameristar window and door work gets done on every address here. Because the community is an unincorporated San Bernardino County pocket wedged between the city of San Bernardino and the foothills, our installations are permitted through San Bernardino County Building and Safety, not the city — unlike our Ameristar repair in Rialto. That means different plan-check schedules, different inspection paths, and a different inspector than a San Bernardino city contractor would expect. We found this out in detail on a ranch house off Cajon Boulevard: a 1990s Ameristar double-hung set had a rotted sill from years of runoff off an unpermitted carport roof the previous owner had built. We pulled the units, rebuilt the framing and sill pan, flashed the new nail fins, set fresh Ameristar builder-line windows, and brought the county inspector through to sign off on the framing same-day. The owner got a watertight opening and a clean paper trail on the carport for the first time. Most Muscoy houses are older, self-built, or owner-improved stock on big lots with detached garages and outbuildings. When a window opening was framed forty years ago by the homeowner’s uncle with a Skilsaw, we plan for the correction work before we ever order glass.
Ameristar Models & Products We Service in Muscoy
We service the Ameristar lines that actually show up in Muscoy homes: the Mason and M/L series single-hung and double-hung vinyl windows, the slider and double-hung builder-line replacement units sold through supply yards, and the half-lite fiberglass and steel entry doors with Ameristar by Ply Gem branding. We keep factory-style Ameristar-compatible hardware on hand locally, sash balances, tilt latches, weatherstrip, and glass, sourced through building-supply and aftermarket channels that match the actual series. A twenty-year-old builder-line window does not need a whole-unit replacement for a broken balance. When the frame is cracked or the nail fin has rotted into the sheathing, we’ll recommend a full window replacement and install a new Ameristar or comparable unit built for Muscoy’s heat and wind. Hampton Contractors is an independent Ameristar service provider, not a factory-authorized dealer or warranty representative.

FAQs – Ameristar Construction in Muscoy
It depends on the frame. Fogged glass on an otherwise square Ameristar frame is often fixable with a new sealed unit and fresh perimeter seal. If the vinyl frame is cracked, the nail fin is rotted into the sheathing, or we’ve already resealed it twice, full replacement is the better spend. Call (833) 467-4075 and we’ll assess it on site, free.
They hold up as well as the installation allows. Ameristar builder-line windows were engineered for volume construction, not extreme inland UV, and the original gaskets and weatherstripping degrade faster here than in coastal climates. Proper flashing, correct shimming, and fresh seals make the difference. We install for Muscoy conditions, not a spec-sheet ideal.
San Bernardino County. Muscoy is unincorporated county land, so the county Building and Safety department permits and inspects window and door replacement work. We schedule our Ameristar installations around the county’s timeline and get the rough opening flushed with the county inspector watching the flashing details.
For a garage or ADU conversion in Muscoy, Ameristar slider and double-hung replacement units sized for the existing rough openings usually make the most sense. Many of these old outbuildings have non-standard openings, so we measure everything before ordering. If the frames are too far gone, we bring in new Ameristar builder-line units and re-frame as needed.
If the slab is sound and the hinges aren’t pulling, a slab swap and re-seal often works. If the slab is delaminating from sun exposure or the jamb is racked, replacing the whole pre-hung unit is usually the better move. Either way, we show you the numbers on both options before you decide. Estimates are free, call (833) 467-4075.
