The Ultimate Exterior Cleaning Guide: Windows, Walls, and Walkways

Your home’s exterior is the first thing people notice, and over time, weather, dirt, grime, and environmental factors can take a toll on its appearance. Maintaining your home’s exterior isn’t just about curb appeal—it’s about protecting your property from long-term damage, increasing its value, and ensuring a healthy, clean environment. This ultimate guide will take you through cleaning three crucial elements of your exterior: windows, walls, and walkways. Whether you’re a DIY enthusiast or considering hiring a professional, these tips will help you get started.


Why Exterior Cleaning Matters

Before diving into the specifics, it’s important to understand why regular exterior cleaning is essential. Dust, pollen, mildew, algae, and pollution accumulate on surfaces, slowly degrading them over time. Unchecked, this can lead to staining, decay, and even costly repairs.

Key Benefits of Regular Exterior Cleaning:

  • Improved Curb Appeal: A well-maintained exterior looks inviting and attractive.
  • Increased Property Value: Clean, well-kept exteriors add value to your home.
  • Protection from Damage: Regular cleaning helps prevent damage caused by dirt, mildew, mold, and algae.
  • Healthier Living Environment: Removing allergens like mold and pollen creates a cleaner outdoor atmosphere.

Now, let’s break down how to clean each area.


1. Window Cleaning: Crystal Clear Views

Clean windows can brighten up the inside of your home, offering clear views and making rooms feel larger and more welcoming. However, they tend to accumulate dirt, water spots, and grime quickly, especially if they’re exposed to rain, wind, or pollution.

Steps for Effective Window Cleaning:

  • Start with Dusting: Before using any liquid cleaner, use a microfiber cloth or duster to remove loose dust and debris from the window frames and sills.
  • Use the Right Cleaner: You can use a commercial glass cleaner, but a simple DIY solution of water, white vinegar, and a few drops of dish soap works just as well. Spray the cleaner generously on the window.
  • Wipe the Windows: Use a microfiber cloth or a squeegee to wipe the windows, starting from the top and working your way down to avoid streaks. For stubborn spots, use a soft scrubber.
  • Dry Thoroughly: Finish by drying the edges of the windows and frames with a lint-free cloth to prevent watermarks.

Bonus Tips for Window Cleaning:

  • Clean Windows on a Cloudy Day: Direct sunlight can cause the cleaner to dry too quickly, leaving streaks behind.
  • Don’t Forget the Screens: Remove window screens and hose them down to remove trapped dust and dirt.

For higher windows, consider using extension poles or hire a professional to avoid safety risks.


2. Walls: Keeping Your Home’s Exterior Fresh

The exterior walls of your home, whether brick, wood, stucco, or siding, are exposed to harsh elements year-round. Dirt, algae, and mildew buildup not only look unsightly but can also lead to long-term structural damage if not addressed.

Cleaning Exterior Walls:

  • Assess the Material: Different wall surfaces require different cleaning methods. For example, vinyl siding can be pressure washed, while wood may need gentler techniques.
  • Start with a Rinse: Using a garden hose or a pressure washer on a low setting, gently rinse the walls to remove loose dirt and debris.
  • Apply a Cleaning Solution: For most surfaces, a solution of water, dish soap, and a little vinegar or bleach will work well. Apply this with a soft brush or a sprayer, working in small sections to avoid drying before rinsing.
  • Scrub Gently: Use a soft brush to scrub areas with mildew or stains, particularly on north-facing walls where mold grows more easily.
  • Rinse Again: After scrubbing, thoroughly rinse the walls with clean water to remove any leftover cleaner.

Pressure Washing for Walls: If using a pressure washer, be cautious with the pressure settings. Too much force can damage softer surfaces like stucco or wood. Keep the nozzle at least 12 inches away from the wall and use a wide spray pattern for even cleaning.

Bonus Tips:

  • Inspect for Damage: While cleaning, check for any cracks, peeling paint, or mold growth. It’s easier to fix small issues before they become bigger problems.
  • Annual Maintenance: Cleaning your exterior walls once a year will keep your home looking fresh and prevent long-term damage.

3. Walkways and Driveways: A Welcoming Path

Your walkways and driveways are subjected to constant foot and vehicle traffic, which can lead to stubborn stains, oil spots, moss, and algae buildup. Regular pressure washing not only enhances appearance but also prevents slippery surfaces caused by moss and algae.

Steps to Clean Walkways and Driveways:

  • Clear the Surface: Start by sweeping away loose dirt, leaves, and debris.
  • Choose the Right Pressure Washer: For concrete, a medium to high-pressure setting is ideal. You can rent a pressure washer if you don’t own one. Ensure you use a nozzle designed for surface cleaning to avoid damaging the concrete or paving stones.
  • Pre-Treat Stains: For oil spots or tough stains, use a degreaser or a specialized concrete cleaner. Let it sit for a few minutes before scrubbing with a stiff brush.
  • Pressure Wash: Use a sweeping motion with the pressure washer to cover the entire surface evenly. Be careful not to linger too long on one spot to avoid etching the concrete.
  • Rinse and Dry: After washing, rinse off any remaining soap and let the area dry completely.

Bonus Tips for Walkways:

  • Add a Sealant: Once clean, consider applying a sealant to your driveway or walkway to protect against future stains.
  • Remove Weeds: While cleaning, check for weeds growing between pavers or cracks, and remove them to keep your walkways looking neat.

Combining Window, Wall, and Walkway Cleaning for Maximum Curb Appeal

For a truly polished look, coordinate your window, wall, and walkway cleaning efforts. Cleaning all three elements at once will instantly transform your home’s exterior, giving it a like-new appearance. Start with the walls, then move on to the windows, and finish with the walkways for a comprehensive, satisfying result.

When to Hire Professionals

While DIY cleaning can be satisfying and cost-effective, there are times when it’s best to hire professionals:

  • High or hard-to-reach windows that require special equipment or safety precautions.
  • Stubborn wall stains or mildew that doesn’t respond to regular cleaning methods.
  • Large driveways or extensive walkways that require powerful, commercial-grade pressure washers.
