Reno, Nevada
Reno exteriors: 4,500 feet of UV, hard freeze-thaw swings, and the product list that answers them
Downtown sits near 4,505 feet and the ground keeps climbing toward the southwest bench. Add a daily temperature swing most of the country never sees and a wildland edge on the west side, and the glass and the cladding are largely decided before anyone opens a colour chart.

What is on the wall now, by Reno build era
The decade a house went up tells us more about what is coming off the wall than anything visible from the driveway, because Reno was not built in one push.
1900 to 1935. Wood double-hung sash, a real amount of it still single-glazed and still working. The question is rarely which brand. It is whether the opening takes an insert unit that keeps the existing frame and trim profile, or a full-frame replacement that does not.
1950 to 1965. The largest cohort we replace. Aluminium sliders and jalousies, single pane, no thermal break in the frame. The metal is the bridge, which is why condensation forms on the frame before the glass, and why new glass in the same aluminium frame fixes half the problem.
1970s and 1980s. Early combination units over hardboard and T1-11 cladding. Hardboard delaminates from the bottom edge up; T1-11 opens along the grooves. Both fail from the back, so the face you can see is the last place to look.
1990s to 2008. First-generation vinyl and clad windows, then a long run of builder-grade vinyl now at or past service life: balances that will not hold a sash, hardware no longer in production, sealed units gone hazy.
Era is a starting point, not a diagnosis. We confirm frame material, glass build-up and substrate condition at the measure visit.
Glazing
Specifying glass at 4,500 feet, and for a 40-degree day
Two conditions do most of the damage to a sealed unit here.
Elevation loads the glass with light. Thin, dry air scatters less of what passes through it, so the same window takes more ultraviolet here than at sea level, and more on the south and west than on the north. A low-E coating reflects infrared and ultraviolet while letting visible light through: heat out on an August afternoon, heat in on a January night, and slower bleaching of floors under a big south window.
The daily swing works the seal. A gap of 35 to 40 °F between afternoon high and overnight low is routine across the valley floor for most of the year, and the gas fill inside a sealed unit expands and contracts with it, every twenty-four hours, not once a season. Because that is fatigue, it argues for spending on the edge construction and not only on the coating.
Before we quote anything we read the certified rating label for the exact unit rather than a brochure range: U-factor, solar heat gain coefficient, visible transmittance and air leakage. West and south elevations get a lower solar heat gain coefficient; on a shaded north wall that trade is not worth making and we keep the daylight. Whether a line is ENERGY STAR certified for our climate zone is on the same label. On any bedroom we also measure the net clear escape opening. A fixed unit cannot serve one, and a slider that drops into the existing rough opening can still fall short.
Cladding
Fiber cement, LP SmartSide or vinyl on a Reno wall, and what the wildland edge does to that choice
On most of the valley floor the material decision is an exposure decision. On the west side of town it stops being one.
That rim sits in wildland-urban interface, and the interface code pushes exterior construction toward ignition-resistant materials, which moves the conversation to fiber cement and away from vinyl. It also moves part of the scope off the wall, because embers get in at soffits, vents and deck framing rather than at the face of a lap board.
Off that line, each material has a cost:
- Vinyl (Alside). Lowest installed cost, colour moulded through, no repaint cycle. But the colour is fixed at the factory, so a deep shade on a west wall cannot be walked back.
- Fiber cement (James Hardie). Holds a painted finish longest and takes radiant heat without moving. Heavy, needs dust control and frequent blade changes, and the dearest of the three in labour.
- Engineered wood (LP SmartSide). Lighter and faster to hang, in longer boards with fewer butt seams. Seams are where freeze-thaw gets a foothold.
That last point is the Reno-specific one. Freeze-thaw runs roughly October to May at valley elevation, and the damaging version is not a cold night. It is water that gets behind the cladding on a warm afternoon and freezes after dark, lifting flashing laps, splitting sealant beads and opening the cut edges of hardboard and oriented strand board. The barrier, the flashing and the kickout at the roof-to-wall junction do more for the wall than the panel on the front of it.
The Washoe Zephyr belongs in the same paragraph: a thermally driven downslope wind off the Sierra, from the west and southwest, up mid-afternoon into the evening, mostly in summer, gusty rather than steady. It is why fastener schedule and nailing pattern are not details we let a crew improvise.
Product lines
What goes on a Reno house, and which line it comes from
Six manufacturers, stocked and ordered directly. Which one belongs on your elevation depends on orientation, substrate and what you want to be doing to the wall in fifteen years.
- Windows: Andersen, Jeld-Wen, Alside. Hung, casement, slider, picture, bay and bow, in vinyl, fiberglass and clad frames. Casements seal tightest on a wind-facing wall; sliders cost less and want a clean track.
- Siding: James Hardie, LP SmartSide, Alside. Lap, board and batten and panel profiles in fiber cement, engineered wood, vinyl and metal, with the barrier and flashing detailed underneath rather than assumed.
- Entry and patio doors: Codel. Fiberglass, steel and glass entry doors, sliding and French patio doors, and pet doors set into the glass. Threshold and hardware decide how a door feels in year five.

How it runs
What a Reno measure visit produces
Nothing gets quoted from a photograph. We work the house elevation by elevation, because on a Reno lot the north wall and the west wall are two different specification problems on the same building.
- Every opening measured, with orientation, shading and access noted
- Substrate checked where the trim allows it: sheathing, barrier and sill
- A written product list: line, style, glass package or profile and colour
- The manufacturer's own rating and warranty documents handed over with it
- Two materials priced side by side wherever the elevation makes it a real choice
- The freight window the manufacturer gives us, not a date invented to close a sale
Reno specifics
Questions that only come up at this elevation
The west wall takes the two loads that age an assembly fastest, and takes them together: afternoon sun at the hottest part of the day, which drives a dark frame's surface temperature well above air temperature, and the downslope wind off the Sierra. Sun cycles the sealant and the gas fill; wind drives dust and moisture at the joint the sealant is holding.
Not the way you would on a sheltered lot. That edge sits in wildland-urban interface, and the interface code steers cladding toward ignition-resistant materials: fiber cement and engineered wood rather than vinyl. Embers also get in at soffits, vents and deck framing, so we check which side of that line an address falls on before pricing a material.
No, and that is a product limit rather than a style preference. A fixed unit does not open, so it cannot serve as an emergency escape and rescue opening. The residential code sets 5.7 square feet of net clear area, or 5.0 square feet at grade-floor level, with a minimum clear height of 24 inches, a minimum clear width of 20 inches and a sill no higher than 44 inches. Net clear is measured after the frame and the sash, so a slider that fits the rough opening can still miss it.
Next step
Tell us the Reno address and which way the worst wall faces
Orientation is the first thing we ask about a Reno house, because it changes the answer more than square footage does. Give us the street and roughly when the house went up. We will measure every opening, elevation by elevation, and put the product list in writing: line, style, glass package or profile and colour.
