Every spring, after months of cold weather, we venture outside and start to notice things like a crack in the siding, sagging gutters, or a deck that looks years older than it did in September. Ignoring these signs costs money, often thousands of dollars more than catching them early.
1. Clean Your Gutters & Downspouts
Gutters are one of the most overlooked and most consequential items on any spring maintenance list. After a full winter of leaf accumulation, ice, and debris, clogged gutters can no longer do their job: directing water away from your home's foundation and structure.
The first step is pulling out the large debris, twigs, clumped leaves, anything solid. What remains below is where it gets messy, but there's a clever DIY hack using a repurposed milk jug that makes scooping out gutter debris far easier without expensive tools.
Flush gutters with a garden hose and have water should run freely through downspouts. Check that downspouts direct water at least 4–6 feet away from the foundation. Then, look for sagging sections or loose hangers — reattach or replace as needed. Inspect joints and end caps for leaks; apply gutter sealant where needed.
2. Inspect Your Roof for Winter Damage
Winter storms with ice, snow loads, and freeze-thaw cycles are hard on roofing materials. Spring is the right time to assess the damage before it worsens through spring rain. The good news is a basic inspection doesn't require you to climb onto the roof.
A pair of binoculars or a smartphone with a zoom camera lets you scan for missing or lifted shingles, damaged metal flashing around chimneys and vents, and any areas where the surface looks buckled or bruised. If anything looks off, call a licensed roofer rather than attempting repairs.
Check metal flashing around the chimney, skylights, and vent pipes. Look for granule buildup in gutters (sign of shingle wear and check attic for signs of water intrusion like staining, mold, or daylight gaps
3. Service Your Central Air Conditioning System
Your central AC unit sat idle all winter. Before you flip it on for the first time in May, give it some attention because a unit that hasn't been inspected is more likely to fail on the hottest day of summer, when HVAC technicians have weeks-long wait lists.
At HouseCalls, we recommend scheduling seasonal AC maintenance now, before the heat sets in. Beyond a professional tune-up, there are several things you can do yourself to maintain your AC unit.
4. Seal Cracks & Gaps on the Exterior
Freeze-thaw cycles are relentless. Water seeps into tiny gaps, freezes, expands, and widens them. By Spring, your home's exterior caulking and sealants may have failed in spots you didn't notice last fall. A slow walk around your home's perimeter with a tube of exterior caulk can save you considerably on energy bills and moisture damage.
This is especially important where wood expands and contracts seasonally like around window frames, door frames, where siding meets trim, and anywhere different materials meet. Pay special attention to the bottom course of siding and any penetrations where pipes or cables enter the wall. Inspect brick mortar joints for crumbling or gaps. Additionally check weatherstripping on exterior doors and replace weatherstripping if compressed or torn.
5.Clean Outdoor Surfaces (Deck, Patio & Siding)
Winter leaves behind a season's worth of grime, algae, mildew, and discoloration on every outdoor surface. Your deck, patio, patio furniture, fiberglass entry doors, and painted siding all benefit from a thorough spring cleaning, and it makes your property look dramatically better almost instantly.
We recommend mixing a concentrated oxygen-powered powdered cleaner with hot water in a garden sprayer, applying it to the surface, letting it dwell for a few minutes, agitating lightly with a scrub brush, and rinsing. This approach lifts dirt, mildew, algae, and fungus without the surface damage that excessive pressure washing can cause on wood decking and painted siding. When you’re ready, we have tips on staining and sealing a wooden deck.
6. Overseed Bare Spots & Revive Your Lawn
A full winter of heavy snow, and objects left on the grass can leave your lawn looking patchy and tired by April. Spring is one of the two best times of year to overseed — the soil is warming up, moisture is plentiful, and grass seed has ideal conditions to germinate before summer heat arrives.
Rake away dead thatch and debris before any seeding or feeding. Identify bare or thin patches — loosen soil 1–2 inches deep before seeding. Apply grass seed matched to your climate zone and sun exposure with these tips about seeding your lawn in the Spring.
7. Check the Basement & Crawl Space for Moisture
Spring snowmelt and rain are the biggest drivers of basement water intrusion. A small leak that went unnoticed all winter can develop into mold, structural damage, or a flooded utility room once the ground becomes fully saturated. This is one of the more important , and most overlooked, spring checks.
Walk your basement perimeter after a heavy rain and look carefully for water stains, efflorescence (the white mineral deposits left by evaporating water), or any standing moisture. Use a moisture meter in crawl spaces and check that vapor barriers are intact and that there's no mold on joists or insulation.
Consider running a dehumidifier in your basement from spring through fall, targeting 50% relative humidity. This alone dramatically reduces the conditions that allow mold to grow and wood to rot, protecting your home's structure over decades.
8. Inspect Windows, Screens & Doors
With windows thrown open on the first warm days, any gaps in screens become an immediate problem. Spring is the right moment to pull out every window screen, inspect it for tears or bent frames, and clean the tracks of your double-hung windows.
9. Change HVAC Filters & Prep Your Heating/Cooling System
HVAC filters should be changed every one to three months depending on the filter type and household conditions — but at minimum, spring is one of those mandatory change points. A clogged filter reduces airflow, makes your system work harder, raises your energy bill, and degrades indoor air quality. This is a two-minute task that most homeowners delay for six months too long.
Have HVAC ducts professionally cleaned if you notice excessive dust or haven't done it in 5+ years. While you’re at it, test smoke detectors and carbon monoxide detectors and replace batteries. Test and reset GFCI outlets in bathrooms, kitchen, and garage.
10. Watch for Pest Activity
Spring is when insects and rodents become active.
Walk the perimeter looking for mud tubes along the foundation (termite sign). Probe exposed wood near the foundation and crawl space for soft spots. Check attic and eaves for wasp or hornet nests starting to be built. Look for rodent droppings or chewed materials in garage, basement, and utility areas. Seal any gaps in the exterior or where pipes penetrate exterior walls. Ensure firewood is stored away from the home's exterior — at least 20 feet.
A little work now equals a lot of savings later
Routine spring home maintenance isn't glamorous, but it's one of the highest-return activities a homeowner can undertake. Catching a roof issue or a failing caulk joint before they become water damage events can save thousands of dollars and months of stress.
Work through this checklist over a weekend or two, tackle what you can yourself, and call in professionals for the jobs that require them.
