With homes subjected to all types of weather day in and day out, it’s no surprise that siding can fall victim to damage, deterioration or improper installation over time. Left unchecked, minor siding issues have a way of growing into bigger problems that require more extensive repairs.
But with some know-how, many common siding problems homeowners encounter can be diagnosed and fixed before they get to that point. Let’s look at a few frequent offenders and how to address them, so you avoid potential headaches and expenses down the line from putting off needed home siding replacement or exterior renovation.

Cracking or Spalling
Changes in temperature and moisture are natural enemies of the siding on your home. Over years of exposure, cracks may appear or small pieces may start spalling off the surface. This is typically more common with fiber cement or vinyl siding in older homes. Gaps let water penetrate the wall cavity, accelerating damages. Apply caulk or wood filler as needed, following with fresh paint. Or in severe cases, replace individual problem boards or panels.
Loose or Lifting Panels
Proper attachment is critical for long-term siding performance. Loose panels allow air and water intrusion behind. They are prone to further damage or being blown/knocked off completely in storms. Re-secure loose panels with siding nails or screws driven at an angle through the face of the panel back into wall sheathing.
Dents, Holes or Gouges
Impact damage may occur for various reasons – lawn equipment, tree branches, hailstorms, etc. For fiber cement or vinyl, fill gouges/holes with matching exterior-grade silicone caulk or wood putty. Light sanding may be needed first for adhesion. Deeper holes require patching with a siding repair kit. Dents can sometimes be carefully popped back out from behind with a damp sponge.
Peeling, Cracking or Fading Paint
Proper surface preparation and quality paint goes a long way for wood siding’s appearance and protection. But even the best maintenance can only slow natural fading over decades. Scrape and sand any peeling areas before recoating. Consider patching or spot-priming severely damaged spots as needed before repainting the whole wall for a uniform look.
Mold or Mildew Growth
This unsightly surface contamination indicates excess moisture problems that need addressed. Improve drainage, ventilation and overhang extensions. Scrub affected areas with a mild bleach solution, rinsing thoroughly to remove. Then apply a mold-resistant primer/paint designed for exterior use. Landscaping that’s grown too close should also be trimmed back.
Be wary of ignoring these and other ongoing siding issues, as they often signal bigger moisture-related problems developing within the wall cavity. Maintaining good drainage, ventilation, sealing and protective exterior coatings prevents future headaches and costs down the line from requiring expensive home siding replacement or extensive exterior renovation work.
Addressing smaller problems promptly helps preserve your home’s siding and curb further damages. Reach out to professional siding installers if things seem to be getting out of hand. Their expertise can help diagnose underlying issues and advise the best repair or upgrade options.
