Spring Checklist: What Central Coast Homeowners Should Do in March and April
Spring on the Central Coast is short and busy. Between rainy season ending in late February and the first 90-degree days that show up sometime in mid-May, you have a narrow window to get your house ready for summer. Skip this list and you will either be doing catch-up work in August when it is 100 degrees outside, or worse, you will learn about a problem when your AC fails during the first real heat wave.
Here is what should be on every Central Coast homeowner’s spring maintenance list.
1. Clean Your Gutters and Check the Downspouts
Winter rains drop oak leaves, pine needles, and whatever else into your gutters. Clogged gutters during a dry summer are not an emergency, but they are during the next winter — and by then you have forgotten. Spring is the clean-out window. While you are up there, check that downspouts drain at least five feet from the foundation.
2. Service the AC Before May
Central Coast HVAC contractors are booked solid in June and July. If your system has not been serviced in the last year — changed filter, cleaned coils, checked refrigerant — schedule it now. Expect to pay $150 to $250 for a standard residential service call. A unit that limps through spring will fail in the first 100-degree week of summer, and same-day service in July does not exist.
3. Test Your Irrigation
Run every zone. Look for broken heads, clogged drip lines, and dead valves. A drought-tolerant landscape still needs deep, infrequent water in summer — if your irrigation is broken, you will lose plants before you notice. While you are at it, pull a couple of drip emitters and check they are delivering the rated flow; clogs are more common than most homeowners think.
4. Inspect Your Roof and Attic
Binoculars from the ground work fine for the first pass. Look for lifted shingles, cracked tiles, and flashing that moved during winter storms. While you are up there, check for rodent droppings in the attic — rats and mice overwinter in attics and spring is when they start breeding. A baited trap now saves you a nest later.
5. Check for Termite Swarms
March through June is swarming season on the Central Coast. If you see flying termites or small piles of wings near windowsills, call a licensed pest inspector. Drywood termites are endemic in Paso Robles and SLO County — it is less a question of if and more when.
6. Get Ahead of Ant Season
Argentine ants will find your kitchen by May if they have not already. Perimeter treatment in early spring, before they are actively foraging, is dramatically more effective than chasing them with sprays once they are inside.
7. Begin Fire-Season Prep Now
Defensible space work is easier in March when it is cool than in July when it is 100 degrees. Clear the first five feet around your structure of combustible material. Thin shrubs under trees. Clear the roof and gutters (you are already up there). If insurance renewal is coming up in the next 90 days, this work is what the underwriters are checking. See the full fire-season guide for the deeper version.
8. Plan Your Wildflower Cutback
If you have native California wildflowers — lupine, California poppies, clarkia — cut them back after they have finished setting seed, usually late May or early June. Cutting too early loses next year’s seed bank. Marking calendar reminders now means you will not miss the window.
9. Well and Septic Season
If you are on a well or septic — and plenty of Paso Robles, Creston, and outlying SLO County properties are — now is inspection season. Septic pumping every three to five years. Well water testing at least annually, with nitrates, bacteria, and, depending on your location in the North County, boron and uranium. If you have not done either recently, spring is the right time. Do not wait for a problem.
10. Walk Your Property Line
Winter winds drop branches, storms push fences, and adjacent construction can encroach without you noticing. A 30-minute walk of your property every spring catches problems while they are still small. Take photos. If anything has changed since last year, you will see it in the comparison.
The Bottom Line
Ninety minutes over a weekend in March or April saves you a much harder day in August. And when it comes time to sell, the homes that show the best in photos are the ones that have been maintained year after year — not the ones staged for a weekend.
