The Complete Maine Spring Home Inspection Checklist

Maine winters are beautiful — and brutal. By the time April arrives, your home has endured months of freeze-thaw cycles, heavy snow loads, ice dams, road salt, strong winds, and sustained cold that stresses every material in your home's envelope. Spring is the time to find out what winter did.

In my years doing home improvement work in the Saco area, I've learned that catching problems in April or May is almost always dramatically cheaper than discovering them in October when you've lost a whole season and things have progressed. Use this checklist as your guide — and if you find issues beyond your comfort level, don't hesitate to call a professional.

🏠 Exterior — Start Outside

Walk the full perimeter of your home on a dry day and work systematically from roof to foundation.

• Look for missing, curled, or cracked shingles from ground level (binoculars help)
• Check for granule loss — bare or shiny patches on asphalt shingles
• Inspect flashing around chimneys, skylights, and vent pipes for gaps or rust
• Look for sagging or uneven roof lines (may indicate structural issue or rot)
• Check for moss or lichen growth (holds moisture, accelerates shingle deterioration)
• Look at the ridge cap — is it still intact and centered?

• Clear all debris from gutters — leaves, pine needles, seed pods
• Flush downspouts with a garden hose — confirm water exits at the base freely
• Check gutter hangers — any pulling away from the fascia?
• Look for cracks, holes, or rust spots in gutters
• Confirm downspouts direct water at least 3–4 feet away from the foundation
• Look for any sections that slope toward the house rather than away

• Check all caulk joints — around windows, doors, corner trim, where siding meets foundation
• Look for cracked, buckled, or missing siding panels
• Check wood trim for soft spots, paint failure, or rot
• Inspect window and door frames for water infiltration stains
• Look for gaps where utility lines enter the home — prime spots for pests and moisture

• Walk the foundation line looking for new cracks (horizontal cracks are most serious)
• Check that soil grades away from the foundation — minimum 6 inches drop in 10 feet
• Look for efflorescence (white chalky mineral deposits) — indicates water moving through masonry
• Check window wells — clear of debris, with proper drainage
• Inspect the sill plate (where foundation meets framing) for rot or insect damage

• Probe deck boards with a screwdriver for soft spots or rot
• Check all railings for stability — push and pull firmly on each section
• Inspect posts where they meet footings or decking for rot
• Check ledger board flashing if deck is attached to house
• Look for raised fasteners (frost heave) and reset or replace them

🏚️ Attic — Don't Skip This

The attic shows evidence of roof leaks and ice dam damage that may not be visible from outside. Put on old clothes and take a flashlight.

• Look for water stains on rafters, sheathing, or insulation
• Check for daylight coming through the roof deck (visible gaps = water entry)
• Smell for mold or musty odors — early mold detection before it spreads
• Confirm attic vents are unobstructed (ridge vent, soffit vents, gable vents)
• Check that bathroom and kitchen exhaust fans vent to the exterior — not into the attic
• Look for evidence of pests — squirrel/raccoon chewing, mouse droppings, insect nests

🌊 Basement & Crawl Space

• Check for standing water or new water stains on walls and floor
• Run your hand along foundation walls — any wet patches or weeping?
• Inspect sump pump — pour a bucket of water in the pit to confirm it activates
• Check sump pump discharge line — is it clear and directed away from the foundation?
• Look for efflorescence on masonry walls
• Check rim joists (where the floor framing meets the foundation) for rot or mold
• Inspect any exposed pipes for freeze damage or small leaks
• Check crawl space vapor barrier — intact and covering all exposed soil?

🔥 Heating System

• Change furnace/air handler filter (should be done every 1–3 months)
• Schedule annual boiler or furnace service before heating season (book in spring, before fall rush)
• Check baseboard heaters — clear of dust, no blockages
• Bleed hot water baseboard radiators if you had uneven heat this winter
• Test carbon monoxide detectors — replace batteries if battery-powered
• If you have a fireplace or wood stove, schedule chimney sweep before next season

🚿 Plumbing

• Check all exterior hose bibs — open slowly and look for signs of freeze damage (dripping inside walls)
• Reconnect garden hoses after last frost (mid-May in southern Maine)
• Run water in any rarely-used fixtures to clear stagnant water
• Check under sinks for any slow leaks or water stains
• Test water heater pressure relief valve (consult manual for procedure)
• Check water heater for rust, corrosion, or sediment buildup — flush if needed

🔌 Electrical & Safety

• Test all smoke detectors — replace batteries in battery-powered units
• Test all carbon monoxide detectors
• Check GFCI outlets in bathrooms, kitchen, garage, and exterior — press Test/Reset
• Look in the electrical panel for any tripped breakers or signs of scorching
• Check exterior light fixtures — any water infiltration or corroded sockets?

Prioritizing What You Find

After your inspection, sort findings into three categories:

1. Immediate (fix within 2 weeks): Active water infiltration, structural issues, safety hazards, significant rot
2. This season (fix within 60 days): Minor leaks, caulk failure, small rot spots, gutter repairs
3. Watch and schedule (next year): Cosmetic issues, aging but functional systems, minor surface wear
