Why Spring Cleaning Matters in New England
New England winters are tough on homes. Months of snow, ice, road salt spray, freezing temperatures, and moisture leave their mark on every exterior surface. By the time April rolls around in the Merrimack Valley, most homes are showing the effects — dirty siding, stained concrete, algae-coated decks, and debris-filled gutters.
Spring is the ideal time to address winter's damage before it compounds through summer's humid months. This checklist covers everything you need to inspect, clean, and maintain on your home's exterior to start the season right.
The Complete Spring Exterior Checklist
1. Inspect Your Siding
Walk around your entire home and look for:
- Mold, mildew, or algae growth (especially on north-facing walls)
- Dirt buildup and staining from winter
- Cracked, loose, or damaged siding panels
- Areas where caulking has failed around windows and trim
- Signs of pest activity (holes, nesting materials)
Document any damage that needs repair before cleaning. It's always best to fix damaged areas first, then clean the entire surface for a uniform appearance.
2. Check Your Roof
From the ground (using binoculars if needed), examine your roof for:
- Missing, cracked, or curling shingles from ice damage
- Black streaks (algae growth)
- Moss or lichen buildup, especially on north-facing slopes
- Damaged or missing flashing around vents and chimneys
- Ice dam damage along the eaves
If you notice black streaks or moss, professional roof cleaning can address these issues safely without the damage that DIY methods often cause.
3. Clean Your Gutters
After the last of the spring pollen drops (usually mid-May in our area), clean your gutters thoroughly. Clogged gutters cause water to overflow onto siding and foundations, accelerating mold growth and potentially causing water damage. Check that downspouts are clear and directing water away from your foundation.
4. Wash Your House Exterior
Spring is the most popular time for house washing in the Merrimack Valley — and for good reason. A professional house washing removes winter's accumulation of:
- Road salt spray and mineral deposits
- Mold and mildew that grew during damp winter months
- Pollen and organic debris
- General dirt and grime
This is best done by professionals using soft wash techniques that safely clean without damaging siding, paint, or trim.
5. Inspect and Clean Hardscapes
Your driveway, walkways, patio, and steps all take a beating from winter. Look for:
- Cracks from freeze-thaw cycles
- Salt staining and mineral deposits
- Algae and moss growth making surfaces slippery
- Settled or heaved pavers that create trip hazards
Professional pressure washing removes staining and biological growth, restoring both the appearance and safety of your hardscapes.
6. Prepare Your Deck
Before you drag out the patio furniture, give your deck attention:
- Sweep away accumulated debris and leaves
- Check for loose, warped, or rotted boards
- Inspect railings and stairs for stability
- Look for mold, mildew, and graying
If your deck shows significant graying, algae, or mildew, professional deck cleaning prepares it for staining or sealing. A clean, treated deck lasts significantly longer than one that's neglected.
7. Address Fencing
Walk your fence line and note:
- Leaning sections or loose posts (frost heave is common)
- Green algae or black mildew on surfaces
- Graying and weathering on wood fences
- Damaged or missing boards
Professional fence cleaning restores appearance and prepares wood fences for staining if needed.
8. Check Windows and Screens
- Clean window glass inside and out
- Inspect screens for tears and damaged frames
- Check window seals and caulking
- Clean window wells and sills
9. Evaluate Landscaping Beds
- Remove winter mulch and debris
- Cut back dead perennials
- Edge beds along walkways and driveways
- Apply fresh mulch after spring cleaning is complete (so you don't damage new mulch during washing)
10. Inspect Outdoor Lighting and Fixtures
- Clean light fixtures of winter grime
- Replace burned-out bulbs
- Check that motion sensors and timers work
- Clean house numbers and mailbox
Timing Your Spring Cleaning
In the Merrimack Valley and Southern NH, we recommend this general timeline:
- Late March / April: Inspection and repairs
- April / May: Professional exterior washing (house, roof, hardscapes)
- May: Deck cleaning and prep for staining
- Late May / June: Deck staining, fresh mulch, final touches
Don't Try to Do It All Yourself
While some items on this list are DIY-friendly (sweeping the deck, checking gutters), others are best left to professionals. House washing, roof cleaning, and heavy concrete cleaning require specialized equipment, proper cleaning solutions, and experience to do safely and effectively. Improper technique can damage siding, void roof warranties, or etch concrete.
