A Las Vegas home doesn't wear out the way a Midwest home does. There is no freeze-thaw cycle and very little humidity damage. Instead, three things do the work: relentless UV, 110°F-plus surface temperatures, and short, violent monsoon storms that dump water faster than desert landscaping can absorb it.
Before the heat: March through May
- Replace door sweeps and weatherstripping. Failed seals on a west-facing door can add noticeably to a July cooling bill and let dust into the house.
- Seal exterior caulk lines around windows, hose bibs, and trim. Sun-baked caulk shrinks and cracks in about three to five years in the valley.
- Inspect stucco for hairline cracks and seal them before summer storms drive water into the framing.
- Check fascia, eaves, and any wood trim on the south and west elevations — those faces take the most UV and fail first.
- Reverse ceiling fans to counterclockwise and balance any that wobble. A wobbling fan loosens its box over a season of constant runtime.
- Service or replace failing screens so windows can be opened during the short comfortable evenings in spring and fall.
Before monsoon season: June
| Item | What to check | Why it matters here |
|---|---|---|
| Drainage and grading | Water flows away from the slab | Flash runoff pools fast against foundations on flat desert lots |
| Downspouts and scuppers | Clear, extended 3+ ft from the house | Concentrated discharge undermines soil and stains stucco |
| Roof-adjacent trim and flashing | Sealed, no lifted edges | 60 mph monsoon gusts lift anything already loose |
| Patio covers and pergolas | Fasteners tight, posts sound | Wind uplift is the top cause of valley patio-cover failure |
| Gates and fence posts | No wobble, hardware tight | Dry soil loses grip; wind finishes the job |
| Window and door seals | No daylight, no gaps | Wind-driven rain enters horizontally during storms |
During peak heat: July and August
This is maintenance-light season by design. Exterior work should shift to early morning, and painting in particular should be avoided once surface temperatures exceed the paint's rated maximum — a common cause of premature peeling on valley homes.
- Keep interior work on the list instead: cabinet hardware, door adjustments, drywall patching, shelving, and fixture swaps.
- Watch for doors that begin binding — heat-related framing movement is usually solved with a hinge shim or a strike-plate adjustment, not a new door.
- Check garage door balance and rollers. Garages routinely exceed 120°F, and heat accelerates spring and roller wear.
- After each storm, walk the exterior and photograph anything loose so the repair list is ready for September.
After the heat: September through November
- Repair the storm damage list — fence posts, patio fasteners, screens, and any stucco cracks that opened up.
- Repaint sun-faded south and west elevations while temperatures are in the ideal 60–85°F application range.
- Reverse ceiling fans to clockwise for the cool months.
- Re-seal exterior wood: gates, pergolas, and front doors take the worst UV damage of any surface on a valley home.
- Test heat before the first cold night, and swap any smoke and CO detector batteries at the same time.
- Adjust irrigation timers down for winter — over-watering near the foundation drives the soil movement behind drywall cracking.
