Desert-proofing your home: a Las Vegas summer maintenance checklist
A Las Vegas summer is not like summer most other places. Months of direct, high-altitude UV, surface temperatures that can top 150°F on a south-facing wall, and single-digit humidity all work together to dry out, fade, and crack the materials your home is built from. The good news: a few hours of seasonal upkeep in spring heads off most of the expensive problems before they start.
Service the AC before you need it
Your air conditioner is the one system in a Vegas home you genuinely cannot live without in July. Replace the filter (a clogged filter makes the unit work harder and run hotter), and gently rinse the outdoor condenser coils with a hose to clear dust and cottonwood fluff. Make sure there is at least two feet of clear space around the outdoor unit so it can breathe. If the system is short-cycling, freezing up, or not keeping up on a hot afternoon, get it looked at in spring — HVAC techs are far easier to book in April than during the first 115-degree week.
Inspect exterior paint and caulk
UV is the enemy of exterior finishes here. Walk the perimeter and look for chalky, faded, or flaking paint, especially on south- and west-facing walls and on any wood trim, fascia, or garage-door framing. Then check the caulk lines around windows, doors, and where dissimilar materials meet. Desert sun bakes the elasticity out of caulk, and once it cracks or pulls away it lets water and dust in during monsoon storms. Re-caulking gaps and touching up bare or peeling paint is cheap insurance — bare wood and stucco left exposed degrade fast.
Check the irrigation system
Drip lines and sprinkler heads take a beating from heat and sun. Run each zone and watch for cracked poly tubing, popped emitters, geysers from broken heads, and dry spots where a line has clogged. A small leak you cannot see wastes water all summer and can quietly undermine a foundation or hardscape. While you are at it, adjust the controller for the season — plants need noticeably more water in July than in March, and most controllers let you set a seasonal schedule.
Refresh weatherstripping and seals
Dry desert air shrinks and hardens the rubber and foam weatherstripping around doors and the garage. If you can see daylight under an exterior door or feel a hot draft, the seal has failed and your cooled air is leaking straight outside. Replacing door sweeps and weatherstripping is an easy, inexpensive job that pays for itself in lower cooling bills. Check the garage-door bottom seal too — it is a common gap that lets in heat, dust, and the occasional scorpion.
A few smaller things worth ten minutes
Clear any debris from roof valleys and the few scuppers or gutters a desert home does have, so the monsoon rains drain. Test that exterior GFCI outlets still trip and reset. And look up at exposed beams, pergolas, and fence tops for sun-checked or splitting wood that wants a coat of sealant before it goes further.
None of this is glamorous, but in our climate the homes that hold up are the ones whose owners stay a season ahead of the sun. If any of it turns up something you would rather hand off — peeling paint, a failed seal, an irrigation break, or an AC that is not keeping up — that is exactly the kind of itemized, warrantied work we do.
