Keep Your Siding in Top Shape: Home Exterior Tips

In the San Fernando Valley, your home’s siding endures long periods of intense sun, low humidity, dry winds, and the occasional heavy rain. From hot summers to Santa Ana winds and winter storms, siding in neighborhoods like Porter Ranch, Sherwood Forest, and Knollwood needs regular care to stay strong and maintain curb appeal.

At CertaPro Painters® of Northridge – Granada Hills, CA, we understand the impact of Southern California’s climate on your home exterior. Here are our expert tips for protecting your siding and keeping it looking its best year-round.

Inspect Your Siding Regularly

Inspect your siding every 3–6 months—especially after wind events or seasonal changes. In areas like Chatsworth, Mission Hills, and Northridge South, UV exposure and high temperatures can cause fading, warping, or cracked paint over time.

Look for sun-bleached areas, dry or brittle surfaces, loose panels, and signs of weathering or water intrusion. Pay extra attention to areas around eaves, vents, and sprinkler-exposed siding where damage often starts.

Clean Your Siding Annually

Dust, pollen, and air pollutants can accumulate on siding—particularly in dry climates like the Valley’s. In communities like Granada Hills Charter or near Rinaldi Park, regular cleaning helps maintain a clean, polished look and prevent long-term discoloration.

Use a garden hose or a low-pressure washer along with a soft brush and mild detergent. Gently scrub away any buildup or mildew, and avoid using high pressure, which can damage aging wood or fiber cement siding.

Repair Damage Promptly

In our arid climate, cracks or gaps can easily go unnoticed until they let in pests or moisture from a rare storm. Dry, sunny conditions may also cause caulking to deteriorate or paint to flake.

Small fixes like sealing cracks or touching up paint may be manageable yourself, but larger issues should be left to the pros. At CertaPro Painters® of Northridge – Granada Hills, CA, we offer expert siding repairs and painting services that match the materials and conditions found throughout the San Fernando Valley.
