Fall is one of the best times of year to inspect and clean your home’s exterior.
For Pittsburgh-area homeowners, fall maintenance is particularly important. Leaves, rain, changing temperatures, and winter weather can put additional stress on roofs, gutters, siding, concrete, decks, patios, and other exterior surfaces.
A few hours of preventative maintenance can help your home enter winter cleaner, safer, and better prepared for the months ahead.
But where should you start?
This Pittsburgh fall exterior cleaning checklist walks you through the most important areas to inspect and clean before winter arrives.
Quick Answer: What Should You Clean Before Winter?
Before winter, Pittsburgh homeowners should inspect and, when necessary, clean:
- Gutters and downspouts
- Roof
- Siding
- Windows
- Driveways and sidewalks
- Decks and patios
- Fences
- Exterior drains and drainage areas
- Outdoor furniture and exterior surfaces
- Areas where leaves and organic debris accumulate
The most important priorities are the surfaces and drainage systems that can be affected by falling leaves, standing water, ice, and freezing temperatures.
Why Fall Exterior Maintenance Matters in Pittsburgh
Pittsburgh homeowners deal with a combination of conditions that make seasonal exterior maintenance important.
These include:
- Frequent rainfall
- Mature trees
- Falling leaves
- High humidity
- Shaded areas
- Freeze-thaw cycles
- Winter precipitation
- Organic growth
- Winter salt and road grime
Leaves and organic debris can accumulate quickly during the fall.
If they are left on or around the home, they can contribute to clogged gutters, blocked drainage areas, slippery walkways, and additional organic growth.
Fall is therefore an excellent opportunity to identify problems before winter makes them more difficult to address.
Fall Exterior Cleaning Checklist
1. Clean Your Gutters
Priority: Very High
Gutter cleaning should be near the top of every Pittsburgh homeowner’s fall maintenance list.
As leaves begin falling, they can quickly accumulate inside gutters and downspouts.
Clogged gutters may prevent rainwater from flowing properly.
Look for:
- Leaves
- Pine needles
- Sticks
- Roof granules
- Dirt
- Moss
- Standing water
- Plants growing inside gutters
Don’t forget the downspouts.
A clean gutter doesn’t help much if water can’t flow through the downspout.
After cleaning, make sure water has a clear path away from the home.

2. Inspect and Clean Your Roof
Priority: Very High
Fall is also an excellent time to inspect the roof.
Look for:
- Black streaks
- Algae
- Moss
- Lichen
- Leaves
- Branches
- Accumulated organic debris
Organic growth can be particularly noticeable on shaded Pittsburgh roofs.
Don’t pressure wash asphalt shingles.
Asphalt shingles can be damaged by aggressive pressure washing.
If your roof needs cleaning, a professional roof-washing or soft-washing approach may be more appropriate.

3. Wash Your Home’s Siding
Priority: High
Fall is a good time to remove the dirt, pollen, algae, and mildew that accumulated during the spring and summer.
Cleaning siding before winter can also improve the home’s appearance during a season when landscaping becomes less prominent.
Look for:
- Green algae
- Black mildew
- Dirt
- Pollen
- Spider webs
- Tree residue
- Bird droppings
Vinyl siding and many other residential exterior materials can often be cleaned using soft washing or low-pressure techniques.
The goal isn’t to use the highest pressure possible.
The goal is to use the safest effective cleaning method for the material.

4. Clean Your Windows
Priority: Medium to High
Fall can be an excellent time for professional window cleaning.
Clean windows can make your home look brighter and more maintained as daylight becomes shorter.
Window cleaning can also remove:
- Pollen
- Dirt
- Dust
- Water spots
- Spider webs
- Environmental residue
If you have large numbers of windows or difficult-to-reach glass, professional window cleaning can also eliminate much of the ladder work associated with DIY cleaning.

5. Clean Driveways and Sidewalks
Priority: High
Driveways and sidewalks collect dirt, algae, leaves, and other debris throughout the year.
Fall is a good time to inspect these surfaces before winter weather arrives.
Look for:
- Green algae
- Black staining
- Dirt
- Oil spots
- Leaves
- Moss
- Slippery areas
Cleaning before winter can be especially useful when organic growth has made walking surfaces slippery.
However, cleaning should be performed appropriately for the material.
Concrete, pavers, natural stone, and other hardscape materials may require different cleaning techniques.
6. Clean Your Deck
Priority: Medium
Your deck may not be getting much use once temperatures drop, making fall a convenient time to inspect it.
Look for:
- Dirt
- Algae
- Mildew
- Leaves
- Staining
- Peeling finish
- Damaged boards
Wood requires particular care during cleaning.
Too much pressure can damage the wood fibers and leave the surface rough.
If you’re planning to stain or seal your deck, cleaning and allowing the wood to dry properly should be part of the preparation process.
7. Clean Your Patio
Priority: Medium
Patios can accumulate leaves, dirt, algae, and other organic debris throughout the year.
Pay particular attention to shaded areas.
If you have a paver patio, inspect the joints as well.
Look for:
- Missing joint sand
- Weed growth
- Moss
- Algae
- Dirt
- Staining
If pavers need restoration, cleaning may be combined with re-sanding and sealing.
8. Inspect Your Fence
Priority: Medium
Fall is a good time to inspect fences before winter weather.
Look for:
- Dirt
- Algae
- Mildew
- Rot
- Loose boards
- Peeling paint
- Failing stain
- Damaged sections
Cleaning can help improve the appearance of a fence and prepare it for future staining or sealing.
However, cleaning does not repair structural damage.
Damaged boards or posts should be addressed separately.
9. Clear Leaves Away From the House
Priority: High
Leaves aren’t only a gutter problem.
They can accumulate around:
- Foundation walls
- Window wells
- Drainage areas
- Porches
- Decks
- Walkways
- HVAC equipment
- Exterior drains
Don’t allow large piles of wet leaves to remain against the house for extended periods.
Keeping these areas clear helps improve drainage and reduces moisture-related problems.
10. Check Exterior Drainage
Priority: Very High
Fall is a good time to make sure water has a clear path away from your home.
Inspect:
- Downspouts
- Downspout extensions
- Drains
- Catch basins
- Grates
- Low areas around the foundation
Make sure downspouts discharge water away from the foundation rather than directly against the house.
If water consistently pools near the home, cleaning alone may not solve the problem.
You may need a drainage professional to evaluate the property.
11. Clean Around Outdoor Living Areas
Outdoor furniture, grills, storage areas, and other exterior items can accumulate dirt and organic debris.
Before winter:
- Clean outdoor furniture.
- Remove leaves.
- Clean grills.
- Clear debris from under decks.
- Organize outdoor storage.
- Check areas where water collects.
If outdoor furniture will be stored for winter, cleaning it beforehand can help prevent dirt and organic buildup from remaining on the surfaces for months.
12. Check Exterior Surfaces for Damage
Cleaning isn’t just about making your home look better.
Cleaning and inspection can help you notice problems that might otherwise be hidden.
Look for:
- Cracked siding
- Missing siding
- Loose trim
- Damaged gutters
- Peeling paint
- Damaged caulking
- Cracked concrete
- Loose deck boards
- Damaged fences
- Roof issues
Cleaning does not fix these problems.
Instead, cleaning provides an opportunity to identify issues that may need repair.

What Should You Clean First?
If your fall maintenance budget is limited, prioritize the areas where cleaning provides the greatest preventative benefit.
Priority 1: Gutters and Drainage
Keeping water moving away from the home should be the first priority.
Priority 2: Roof
Address visible organic growth and inspect for potential problems.
Priority 3: Slippery Walkways
Remove algae and organic growth from areas where people walk.
Priority 4: Siding
Clean accumulated dirt, algae, mildew, and pollen.

Should You Pressure Wash Your House Before Winter?
Not necessarily.
The appropriate cleaning method depends on the surface.
Some surfaces may be appropriate for pressure washing.
Others may be better suited to soft washing or low-pressure cleaning.
For example:
- Asphalt shingles generally require a soft-washing approach.
- Vinyl siding often benefits from low-pressure cleaning.
- Concrete may tolerate higher-pressure cleaning.
- Wood requires careful pressure control.
- Painted surfaces require additional consideration.
More pressure does not automatically mean better cleaning.
The safest effective method depends on the material.

Should You Clean Your House in Fall or Spring?
For many Pittsburgh homes, the answer is both.
Spring cleaning addresses:
- Winter grime
- Salt residue
- Pollen
- Dirt
- Algae
Fall cleaning addresses:
- Summer buildup
- Leaves
- Organic debris
- Gutters
- Pre-winter maintenance
The services your home needs may change with the season.
A homeowner with heavy tree coverage, for example, may need more frequent gutter cleaning while only requiring house washing every year or two.
How Pittsburgh Weather Affects Exterior Maintenance
Pittsburgh’s climate makes seasonal maintenance especially useful.
Rain
Frequent rainfall means gutters and drainage systems need to function properly.
Humidity
Moisture can contribute to algae, mold, and mildew growth.
Trees
Mature trees provide shade but also contribute leaves and organic debris.
Winter
Freezing temperatures can make existing drainage and surface problems more difficult to address.
Spring
Pollen and moisture create another period of heavy exterior buildup.
This is why a seasonal maintenance approach makes sense for many Pittsburgh-area homes.
When Should You Schedule Fall Exterior Cleaning?
Don’t wait until the first hard freeze.
Ideally, schedule fall services after the majority of leaves have fallen but while weather conditions are still suitable for exterior cleaning.
For gutter cleaning, timing depends heavily on the trees surrounding your property.
If your home is surrounded by mature trees, you may need to clean gutters more than once during the fall.
It’s also smart to schedule popular services early because exterior cleaning companies can become busy during peak fall maintenance season.
Frequently Asked Questions
What should I clean on my house before winter?
Prioritize gutters, downspouts, roof surfaces, siding, walkways, drainage areas, and other surfaces where leaves, dirt, algae, and organic debris have accumulated.
Should I pressure wash my house before winter?
Not necessarily. The correct cleaning method depends on the surface. Some materials may be better suited to soft washing or low-pressure cleaning.
Is fall a good time to pressure wash?
Fall can be an excellent time for exterior cleaning in Pittsburgh, provided temperatures and weather conditions are appropriate for the specific service.
Should I clean my gutters before winter?
Yes. Cleaning gutters after most leaves have fallen can help keep rainwater and melting snow moving through the drainage system.
How often should I clean my gutters in Pittsburgh?
Many Pittsburgh homes benefit from gutter cleaning twice a year. Homes surrounded by mature trees may need more frequent cleaning.
Should I clean my roof in the fall?
Fall can be a good time to inspect and, when necessary, clean a roof. Visible algae, moss, lichen, and organic debris should be evaluated before winter.
How often should I wash my house?
Many homes benefit from professional house washing every 1–2 years. Homes with heavy shade, mature trees, and recurring algae or mildew may need more frequent cleaning.
What is the most important exterior maintenance before winter?
For most homes, maintaining gutters and drainage should be a top priority. Roof inspection, slippery-surface cleaning, and removal of accumulated organic debris are also important.
The Bottom Line
Fall is an ideal time to prepare your Pittsburgh-area home for winter.
You don’t necessarily need to clean every exterior surface every year.
Instead, focus on the areas that need attention based on:
- Surface condition
- Tree coverage
- Shade
- Moisture
- Organic growth
- Drainage
- Previous maintenance
At a minimum, make sure your gutters and downspouts are clear, water can drain away from your home, your roof is in good condition, and slippery organic growth has been addressed.
Taking care of these items before winter can make spring maintenance easier and help keep your property looking its best year-round.
