When to Replace Siding

Siding gives your home a captivating curb appeal and its own unique personality. It also protects from the elements; keeps the interior warm and dry; and improves energy efficiency. But siding can do all this only if it is well-maintained and not past its prime. Here are some signs to look for to help you decide if your siding needs replacing sooner rather than later.

Age: Like every other product on the market, siding can age past its point of usefulness. While some types of well-maintained siding can last 30 plus years, plan on a 25-year lifespan, regardless of the siding material.

Damage: Replace vinyl or wood siding when it becomes cracked, broken or pieces break off easily. A general rule of thumb is to replace the siding if 50 or more panels are damaged.

General Appearance: Even if it still looks relatively good, you might want to update your home exterior or to replace the siding to match the new add-on.

Surface Appearance: If the siding is warped or seems wavy, it could be an indication of water damage. Other changes in surface texture such as pitting or blistering can also be signs of moisture issues.

Surface Condition: Check for mildew, mold and rot. If it’s taken hold to such a degree where it keeps returning after several thorough cleanings, it might be better to replace the siding. Replacement, particularly if you have wood siding, will probably be more cost-effective in the long run, because rot is an organic growth that eats through the panels.

Loose Seams: When seams are loose and pulling away from your home, rain can get in behind the siding, creating a perfect place for mildew, mold or rot to grow. Replace the siding if the siding panels can no longer be tightened (retain nails).

Improve Energy Efficiency: When you feel a draft or the windows fog, replacing the siding could improve energy efficiency and lower your heating bills. Older siding might have been installed without the proper moisture barrier.

Selling Your Home: If you know that you will be putting the house on the market in the next five years, consider replacing the siding in the near future. It will help increase the resale value.
