The best time to work through a spring maintenance checklist in Colorado Springs is late April through May, after the risk of hard freezes has passed and before summer heat arrives. I walk this same 18-task list on my own house every year, because Colorado winters are hard on houses: over a single winter, your home’s exterior goes through 100+ freeze-thaw cycles, months of intense UV at altitude, and daily temperature swings of 40°F, and by spring everything is a little more beat up than it looks from the sidewalk. It isn’t a generic checklist copied from a national home improvement site (most of those don’t even mention freeze-thaw); it’s built around what I actually see go wrong on houses here, year after year.
Exterior
1. Walk the foundation perimeter Look for new cracks that appeared over winter. Hairline cracks in concrete foundations are common after severe freeze-thaw cycling and often cosmetic. Horizontal cracks in block foundations, stair-step cracks in mortar joints, or cracks wider than 1/4" warrant professional assessment. Document what you find with photos and a date.
2. Inspect caulking at all window and door frames Colorado’s low humidity and strong UV break caulk down faster than in most climates. Caulk that was solid in October may be cracked, shrunk, or pulling away from the frame by May. Press on any spot that looks bad (this is the single most common thing I find in May, on almost every house). If it crumbles or separates, scrape it out and put in new caulk (a high-quality, paintable silicone-latex blend holds up well outdoors). Don’t leave gaps open through summer: water that gets in behind the siding causes damage that costs far more to fix than a tube of caulk.
3. Check painted wood trim and siding for peeling or cracking Colorado’s dry air and intense high-altitude UV break down exterior paint faster than in most places. The wood underneath keeps swelling and shrinking as moisture levels swing between winter and summer, and that movement cracks the paint’s grip on the wood. Scrape off loose paint, prime the bare wood, and repaint before summer sun hits the exposed wood directly. A little spot painting now prevents a full repaint later, once the damage spreads.
4. Inspect the roof from the ground with binoculars Look for lifted or missing shingles, granule loss (bare dark patches on asphalt shingles), and any obvious damage to flashing around chimneys, vents, or skylights. Colorado Springs sees frequent hail storms in spring and summer. If a major storm hit last year and no one has checked your roof since, spring is the time to get it looked at.
5. Clean gutters and downspouts Spring means cottonwood seeds and pine debris after winter winds. Clear gutters of any organic material. Flush downspouts with a garden hose to confirm flow. Check that downspout extensions direct water at least 4–6 feet from the foundation. Pooling water against the foundation after spring snowmelt is a common cause of basement moisture problems.
6. Inspect the deck or patio surface At Colorado Springs elevations, deck stain breaks down 30–40% faster than manufacturer specifications because of UV intensity. Look for greying, flaking, or checking (surface cracks) in the wood. If you’re past two seasons since the last stain application, this is likely a restain year. Boards that have checked or show end grain exposure need prompt attention before summer moisture cycles make them worse.
7. Check fence post conditions Wood fence posts sit right at the soil line, where Colorado’s freeze-thaw cycles hit hardest. Push on each post. If it moves, that means rot or frost heave (the ground pushing the post upward as it freezes and thaws, and I’ve reset plenty of these over the years). Posts that have heaved above grade need to be reset before they pull the whole fence panel out of line.
8. Inspect the driveway and walkways for new cracks Concrete that was intact in October may have cracked after a hard winter. Fill cracks before they widen. Water entering a crack, freezing, and expanding is the mechanism that turns a hairline crack into a significant heave. Concrete crack filler from the hardware store handles cracks under 1/2" wide. Larger damage or sunken sections are worth getting looked at.
Outdoor Water Systems
9. Restore outdoor hose bibs (after May 8) Turn the interior shutoff valve back on for each outdoor hose bib. Before you attach any hose, check for drips at the spigot body and at the connections inside the wall. A frost-free sill cock (the freeze-resistant outdoor faucet with a long stem that reaches into the heated house) that cracked over winter will drip from inside the wall once the water is back on. Find the leak before you let the water run freely.
10. Inspect irrigation system Turn on zone by zone and walk each zone while it runs. Look for broken heads (spraying sideways or not retracting), low-coverage zones, and heads that are sitting too high or too low after soil movement. Adjust before the first hot week in June, not during it.
11. Swamp cooler startup See the swamp cooler vs. AC guide for the full startup procedure. At minimum: replace pads, clean the reservoir, treat with algae inhibitor, check belt condition, and test before hot weather arrives. Waiting until the first 90°F day to discover the unit needs a new pad is a guarantee of a warm house.
Interior Systems
12. Replace HVAC filter Colorado Springs has a long heating season. Once it ends, replace the furnace filter before you switch over to cooling. If you have a whole-home humidifier, remove and clean the water panel and shut off the humidistat. Don’t run the humidifier during cooling season.
13. Test smoke and carbon monoxide detectors Press the test button on each device. Replace the batteries in battery-powered units every year, no matter what the test shows: the test button only proves the alarm can sound, not that the battery has enough charge left for a real emergency. Replace smoke detectors after 10 years and CO detectors after 5 to 7 years (check the manufacture date printed on the unit, since it varies by model).
14. Test GFCI outlets Press the test button on GFCI outlets in bathrooms, kitchen, garage, and exterior locations. The outlet should lose power. Press reset. If it doesn’t trip or doesn’t reset, the outlet needs replacement.
15. Check the water heater Check for rust at the connections, confirm the temperature is set to 120°F, and listen for unusual sounds while it’s heating. Flushing the tank once a year is the recommended maintenance. See the water heater flushing guide if yours hasn’t been flushed in a while.
Outdoor Living Preparation
16. Inspect outdoor furniture hardware Outdoor furniture, swings, and play equipment expand and contract with Colorado’s wide temperature swings, and that constant movement works bolts and screws loose over a winter. Tighten all the hardware. Replace anything too rusted or corroded to work properly. A loose bolt on a swing or a climbing structure is a safety problem, not a minor one: fix it before kids use the equipment again.
17. Service the gas grill Remove the burner grates and clean them. Check the burner ports for blockage (spiders and insects nesting in the gas ports over winter is common, not rare, and I find at least one grill like this every spring). Inspect the propane hose for cracks or brittle spots. Test the igniter. Light all the burners and check for an even flame across the surface.
18. Prepare the garage for summer Spring is when garages fill up with the leftovers of winter: salt bags, snow shovels, ice scrapers. Clear floor space and check overhead storage if you have it. An uninsulated Colorado Springs garage gets hot and sun-baked in summer, which breaks down stored chemicals faster. Move paint, aerosols, and similar materials into conditioned space inside the house instead.
The Payoff
I don’t expect anyone to knock out all 18 in one weekend. This list is about catching what a Colorado winter did to your house before the damage gets expensive. Catch caulk failure in May and you’re looking at about $20 in materials and an hour of your time. Ignore it until October and you’re looking at water behind the siding instead, and that’s a much bigger job (and a much bigger bill).
