The crew that fights Colorado weather for a living.
Altitude ultraviolet, chinook winds and freeze-thaw take coatings apart on a schedule. The preparation is what decides whether yours lasts eight years or three.

Painter Hotline's exterior crew paints siding, trim, fascia, soffits, entry doors and garage doors on the Front Range. Before any color goes on, each house is washed, scraped back to tight paint, sanded smooth at the edges, filled, caulked and primed wherever wood or patches are bare. Strong high-altitude sun, chinook winds that dry paint too fast and constant freezing and thawing all work against exterior paint here, so we paint each side when its exposure allows and choose the product grade for how hard that side gets hit.
Four forces, and all four compound here
Outside paint is not just getting old. Specific things break it down, and on the Front Range several hit the same wall at once.
- Ultraviolet at altitude. Thinner atmosphere filters less. UV attacks the binder holding pigment together, which is what produces fading first and chalking later. Rub a sunny wall: if powder comes off, that coating is finished.
- Chinook winds. Downslope winds accelerate off the foothills, skin a surface before the film underneath has knitted, and drive grit into it.
- Freeze-thaw. Water entering a failed caulk joint freezes, expands and lifts the film from the substrate. Dozens of cycles a winter. This is why caulking is structural work rather than cosmetic.
- Snow reflection. A fresh snowfall reflects sunlight up onto the lower siding, the trim and the undersides of the eaves, which is why those spots often give out first.
Reading your own house before you get bids
| What you see | What it means | What it needs |
|---|---|---|
| Powder on your palm | Chalking. UV destroyed the binder | Thorough washing, then repaint. Coating over chalk guarantees failure |
| Peeling in sheets | Water getting behind the paint, or bare wood that was never primed | Find the water source first, then scrape, prime, repaint |
| Failure only near the ground | Sprinkler overspray, nine times out of ten | Adjust the heads. Cheapest repair available |
| Gaps where trim meets siding | Failed caulk, the main water path | Cut out and reseal with a quality elastomeric sealant |
| Dark streaks on a north wall | Mildew, not dirt | Treat chemically. Painting over mildew feeds it |
| Swollen, soft bottom edges | Hardboard siding taking on water | Replace the failed sections and seal every cut end before coating |
The season, honestly
In practice, exterior season runs from about mid-May into early October. Denver-area climate normals put the average last spring freeze around May 5 and the average first fall freeze around October 7; the higher you go, the shorter that gets. What decides a paint day is the low that night, not the afternoon high: paint put on at a comfortable 65 degrees still has to cure in the dark. If the temperature falls under the product's minimum before it sets up, the bond is weaker, and you will not see it for a year. Our guide to how long an exterior paint job takes lays out the recoat times and month-by-month weather numbers behind our schedule.
If the forecast is wrong for paint, we move the date. It is sometimes a hassle, and it is always the right call.
What is in the scope
- Protect plants, walks, drives, windows, fixtures and vehicles.
- Pressure wash the whole exterior and allow full dry time.
- Scrape every loose edge back to sound material.
- Repair or replace failed substrate, and seal all cut ends.
- Sand transitions so the old paint line does not telegraph through.
- Fill, then caulk every joint, seam and penetration.
- Prime all bare substrate and every repair.
- Two finish coats on siding, trim, fascia, soffit and doors as scoped.
- Full cleanup, then a walkthrough you lead before the balance is due.

Exterior questions
When can you paint the outside of my house?
Generally mid-May through early October. Denver-area records place the average last spring freeze near May 5 and the first fall freeze near October 7, and elevation tightens both ends. The overnight low governs, because the coating cures through the night.
How much does exterior painting cost?
On Angi’s 2026 Denver cost data, exteriors run about $1.55 to $4.10 per square foot of paintable surface. How sound the old paint is, and how much repair sits under it, matter far more than the size of the house. Run the numbers.
Do you pressure wash first?
Always, on every exterior. Paint will not bond to chalk, dust or mildew, and Colorado's sun-facing walls chalk heavily. Washing is part of the scope, not an add-on.
How many coats do you apply?
Two finish coats on siding and trim as standard, with primer specified separately wherever the substrate is bare or repaired. The count is written into your estimate rather than left vague.
Why does my west wall look worse than the rest?
Directional ultraviolet load. West and south elevations take hours of direct afternoon sun, which breaks down the binder in the coating. Those walls commonly need attention a full cycle before north and east.
Can I repaint only part of the exterior?
Yes, and it is often the smart use of a limited budget. Doing the sun-facing elevations now and the shaded ones in a later season matches the spend to the actual wear.
