Fall Exterior Cleaning Checklist for Lowcountry Homes
A good fall exterior cleaning checklist looks a little different in the Lowcountry than it does up north. We don't have to winterize against heavy snow, but we do come out of a long, humid summer with mildew on the siding, pine straw in the gutters, and a salty film on everything near the water. Fall is the best window of the year to reset the outside of your home before holiday guests arrive and winter rains settle in.
Below is the same top-to-bottom order our crews follow on homes in Summerville, Charleston, Mount Pleasant, Goose Creek, and the islands. Use it as a do-it-yourself list, a list to hand to a pro, or a mix of both.
Why Fall Is the Right Time in the Lowcountry
Spring cleaning still matters here because of the yellow pine pollen. But if you only do one full exterior cleaning a year, early to mid fall is often the smartest time. We go deeper on timing in our article about the best time of year to pressure wash in Mount Pleasant.
The Top-to-Bottom Fall Checklist
Always clean from the top down. Dirt from the roof and gutters runs down the walls, so washing the siding first and the roof later means doing the siding twice.
1Roof
- Look for black streaks, green moss, or lichen, especially on north-facing and shaded slopes.
- Check for branches, pine cones, and debris in valleys and behind the chimney.
- Note any lifted, cracked, or missing shingles from summer storms and call a roofer for those.
- Schedule roof soft washing if growth is visible, never a high-pressure blast.
2Gutters and downspouts
- Remove leaves, pine straw, oak tassels, and shingle grit.
- Flush downspouts and confirm water exits away from the foundation.
- Check for sagging sections, loose hangers, and leaking seams.
- Plan a second cleaning after late-fall leaf drop if you have large trees nearby.
Clogged gutters are one of the most common causes of fascia rot and foundation splash staining we see. Our gutter cleaning service includes downspout checks.
3Siding, trim, and soffits
- Look for green algae and black mildew, usually worst on the north and shaded sides.
- Check soffits and eaves for spider webs, mud dauber nests, and mildew spots.
- Look for rust streaks below fixtures and red clay splash along the bottom row.
- Soft wash vinyl, stucco, fiber cement, and painted wood instead of pressure washing.
4Windows and screens
- Clean salt haze and summer storm spots from glass.
- Remove, wash, and dry screens, checking for tears.
- Wipe tracks and sills where pollen and grime collect.
Coastal homes often need this more than once a year. Our window cleaning service can be paired with a house wash.
5Porches, piazzas, and porch ceilings
- Gently wash porch ceilings, including painted beadboard, where mildew hides.
- Clean railings, columns, and ceiling fans.
- Wash porch floors and steps to remove slick algae before wet winter months.
6Decks, patios, and pool areas
- Clean wood decks with low pressure and check for loose boards and popped nails.
- Wash pavers and pool decks to remove slippery algae.
- Plan staining or sealing now while temperatures are mild and the wood is dry.
7Driveways, walkways, and entry
- Pressure wash concrete to remove mildew, tire marks, and leaf tannin stains.
- Treat oil and rust spots before they set in further.
- Clean the front walk and entry steps last so guests see the clean result.
See our driveway and concrete cleaning page for what is included.
8Fences, outdoor furniture, and extras
- Wash fences, especially the shaded side facing the yard.
- Clean outdoor furniture and cushions before storing or covering them.
- Rinse the mailbox, house numbers, lamp posts, and trash can area.
Want the Whole Checklist Done in One Visit?
We can handle the roof, gutters, house wash, windows, and concrete in a single scheduled visit, so you can cross off the whole list at once before the holidays.
A Simple Fall Timeline
You don't have to do everything in one weekend. This spreads the work across the season.
| When | Focus | Why then |
|---|---|---|
| Early October | Roof check and soft wash, first gutter cleaning | Clear summer growth and storm debris first |
| Mid to late October | House wash, porches, windows | Cleaner roof and gutters mean siding stays clean |
| Early November | Decks, patios, driveway, walkways | Flatwork is done last, after runoff from above |
| Late November to early December | Second gutter cleaning, final touch-ups | Catch late leaf drop before winter rain |
Coastal Notes for Islands and Waterfront Homes
If you live on Folly Beach, Isle of Palms, Sullivan's Island, or along the marsh in Mount Pleasant or James Island, add a few items:
- Rinse salt film from siding, railings, and outdoor metal more often to slow corrosion.
- Check light fixtures, hinges, and hose bibs for early rust.
- Clean windows more often, since salt haze builds up faster than inland.
- Look under elevated homes for mildew on pilings, stairs, and storage areas.
Our article on salt air and humidity in Charleston explains why coastal homes usually need cleaning more often.
DIY or Hire a Pro?
| Task | Reasonable DIY? | Notes |
|---|---|---|
| Outdoor furniture and cushions | Yes | Mild soap and a garden hose work well |
| Ground-level windows and screens | Yes | Dry screens before putting them back |
| Small patio or walkway | Usually | Keep the tip moving to avoid etching |
| Single-story gutters | With care | Use a stable ladder and a spotter |
| Two-story siding | Not recommended | Ladder risk and uneven results |
| Roof cleaning | No | Slippery and easy to damage shingles |
What a Professional Fall Visit Looks Like
If you hand the list to a pro, here is roughly how a full fall visit goes so you know what to expect.
- Walkaround first. The crew checks the roof, gutters, siding, and flatwork and points out anything that needs a roofer or repair, not cleaning.
- Prep. Windows and doors are closed, outlets and fixtures are covered, and plants are soaked with water.
- Top-down cleaning. Roof soft wash and gutters come first, then the house wash, porches, and windows.
- Flatwork last. Driveways, walkways, and patios are cleaned after everything above has been rinsed.
- Final rinse and review. Plants get a last rinse, and you walk the property with the crew before they leave.
Most single-family homes can be finished in a day, depending on size and how much growth built up over the summer.
Common Fall Cleaning Mistakes
- Washing the siding before the roof and gutters. Runoff will undo your work.
- Cleaning gutters only once. Many Lowcountry trees drop leaves late, so a second pass is often needed.
- Using high pressure on everything. It can damage shingles, stucco, and wood.
- Ignoring porch ceilings and soffits. Mildew there spreads and is easy to miss from the ground.
- Waiting until mid-December. Holiday schedules fill up fast, so book early.

Frequently Asked Questions
When should I do fall exterior cleaning in the Lowcountry?
Early October through November works best. Summer growth has peaked, hurricane season is ending, and the milder weather is good for cleaning.
What order should I clean the outside of my house?
Start at the top with the roof and gutters, then the siding, windows, and porches, and finish with decks, patios, and driveways so runoff doesn't dirty finished areas.
How many times should I clean my gutters in the fall?
Many Lowcountry homes need two cleanings, one in early fall and another after the late leaf drop, especially with oaks or pines nearby.
Is fall a good time to stain or seal a deck?
Yes. Mild temperatures and lower humidity help stain and sealer cure well. Clean the deck first and let it dry fully before applying.
Do coastal homes need extra fall cleaning?
Usually yes. Salt film builds up on siding, windows, and metal, so waterfront and island homes benefit from more frequent rinsing and window cleaning.
Can I get everything on this checklist done in one visit?
In most cases, yes. A professional crew can combine roof soft washing, gutter cleaning, house washing, windows, and concrete cleaning in one scheduled visit.
