Spring maintenance for your house — after the Swedish winter
Updated 15 June 2026
Swedish winters leave a bill — clogged gutters, tired seals, salt-stained steps, and systems that ran hard for months. Spring maintenance is your reset: clear what winter broke, inspect what you could not see in the dark, and fix small things before summer projects take over. This guide gives a practical timeline from March through May, outdoor work that protects the structure, indoor checks as you ventilate and dry out, and drainage tasks that connect roof to foundation. Treat it as the counterpart to autumn winter prep — same house, different season, same goal of avoiding surprises.
Timeline: March to May
March: assess winter damage when snow melts — gutters, downpipes, cracked tiles visible from ground, drainage paths blocked by ice or grit. Test outdoor taps carefully if they were shut for winter. April: deeper outdoor inspection, first lawn and bed work away from the facade, check crawl space ventilation as ground dries. May: facade wash where appropriate, window seals, deck and balcony fasteners, schedule any roofer or painter visits for summer. Complete FTX filter change if not done in winter prep. Document what you found so next spring starts with a list, not a blank slate.
Outdoors — facade, roof line, and garden
Walk the perimeter: look up at eaves, soffits, and chimney flashing; look down at grading toward the foundation. Clear gutter outlets and window wells of sand and leaves. Check exterior paint and wood for blisters or rot — spring moisture reveals problems summer heat hides. Open outdoor water slowly and watch for pipe leaks. Inspect fences, gates, and retaining walls shifted by frost. Keep soil and mulch from sitting above the line where timber meets ground — a common spring mistake after enthusiastic gardening.
Indoors — air out, dry out, and check systems
Open windows daily for effective cross-ventilation as the house warms — flush winter humidity. Check basements and cold corners for musty smell or new spots on walls. Test smoke and CO alarms; replace batteries on a date you remember each spring. Run heating system briefly on cooler nights until you are sure it still works — better than discovering issues in autumn. Review bathroom silicone and grout after a season of heavy ventilation use. If condensation disappeared in winter but mould spots remain, clean and monitor — they signal a source still unresolved.
Drainage and water paths
Spring melt and April rain test every weak point. Confirm downpipes carry water to storm drains or away from the house. Clear surface drains in the driveway and patio. If the lawn holds puddles against the facade, plan grading or drainage improvements before summer landscaping covers the problem. Check sump pumps if you have them — spring is when they should run, not when you first notice basement damp in November. Roof, gutters, ground slope, and crawl space vents work together; spring is the best time to verify the whole chain.
Checklist: spring home maintenance
Walk the house exterior — roof line, facade, foundation, drains.
Clear gutters and downpipes after winter debris and sand.
Test outdoor water carefully; fix leaks before full summer use.
Ventilate indoors daily; check basement humidity and musty smells.
Test smoke and CO alarms; replace batteries on a fixed spring date.
Inspect deck, balcony, and steps for frost damage and loose fittings.
Confirm ground slopes away from the house; clear window wells and surface drains.
Document findings and schedule summer repairs while tradespeople have capacity.
