The Importance of Proper Siding Maintenance and Repair

Siding is one of the most important elements of your home. It protects your home from wind, rain, and pests.

If your residential siding isn't in proper condition, it can cause major issues down the road, like water damage and mold growth. If left unchecked, this can devalue your home and decrease its value significantly.

Repair Cracks and Holes

Holes and cracks are common in vinyl siding, especially during storms or when the temperature fluctuates. They allow rainwater to penetrate the siding and can lead to extensive damage to the home.

However, small holes can be repaired with vinyl caulk. Look for caulk made specifically for siding at your hardware store or home center.

If the hole is larger, a patch can be applied. These are usually thin, durable, and super-sticky, so they're virtually invisible on the surface of the siding.

Before you repair, ensure the hole is clean and dry. Apply a small caulk in the hole and over the surrounding area.

Once the caulk has dried, use a razor scraper to remove excess and flush the patch with the siding. Then paint the patch to match your siding. This will help it blend in better with the rest of your home's exterior.

Paint or Re-Stain

Paints are popular for exterior siding because they are easy to apply and provide a thick layer of protection. The type of paint you use also affects how long it will last. Acrylic latex paints are the most popular choice among pros and do-it-yourselfers.

They come in various colors and have three finishes: flat, satin, and semi-gloss.

Siding painters will often recommend using a primer before painting. This step is necessary to ensure the paint adheres properly and prevents peeling or blistering.

Paints also tend to fade in the sun, especially on South-facing homes where overexposure to the UV rays causes the wood of the siding to expand. This expansion can cause paint to crack and peel, which can be unsightly and lead to water seeping into the cracks.

Remove Dirt and Stains

Vinyl siding looks like a great investment but can be prone to dirt and stains. These can come from various sources and require regular cleaning to keep your home looking its best.

Mold and mildew are other common problems. They build up in homes prone to heavy rain and humid weather.

When this occurs, a white vinegar and water solution can help lift these stains without harming your vinyl siding.

If you don't want vinegar, mixing 1 cup of bleach and one-gallon water can also be a stain remover. Be sure to test any cleaner on a small area of your siding before applying it to the whole surface, and be sure to wear gloves when using bleach.

For more serious stains, try a cleaner designed specifically for exterior surfaces. These typically contain a blend of oxygen bleach and water, which will cut through stubborn stains.

Replace Loose or Broken Pieces

If you notice a small section of siding that is cracked, loose, or broken, it is relatively easy to replace. You'll need a zip tool, some replacement siding, and a little time to do the job.

First, use a utility knife to remove the damaged area from your siding. Leave a little extra siding around the top of the patch so you can attach it with construction adhesive later.

Second, get a new vinyl siding that matches your home's color and style. Look for one slightly darker than your existing siding to cover up any fading you may have noticed.

Next, nail the new siding to your wall with 1.25-inch roofing nails through the nailing flange, leaving plenty of room for expansion and contraction due to extreme temperatures. Then apply weatherproofing caulk to seal the repair and paint it. This will prevent moisture from entering your home and causing more damage to the siding.
