How Much Does It Cost to Repair Vinyl Siding?

Fortunately, repairing or replacing vinyl siding doesn't have to cost a ton, and you don't need advanced DIY know-how to fix minor issues.

Can You Repair Vinyl Siding?

Vinyl siding hole repair is a relatively straightforward DIY job, provided the hole is smaller than an inch. Simply fill the hole with paintable caulk, smooth it with a putty knife and allow it to dry. You can then paint the caulk the same color as the rest of your siding using exterior paint.

Caulk is also suitable for medium-sized holes measuring more than an inch wide. However, you'll need to unzip the damaged panel first and apply foil tape to the back of the hole. Foil tape supports the caulk and makes your repair more durable.

You can't use caulk to repair major damage. Large holes require a vinyl siding patch made from siding similar to the rest of your house. While some homeowners choose to patch damaged siding themselves, a house siding repair specialist may achieve a more seamless finish.

How Much Does Vinyl Siding Repair Cost?

According to Forbes, vinyl siding repair costs $2 to $4 (CAD 2.74 to CAD 5.48) per square foot or between $200 and $400 (CAD 274 and CAD 548) for a 100-square-foot section. Hiring a professional to fix a single hole typically costs $50 to $100 (CAD 68 to CAD 137) if the hole is small enough to fill with caulk.

Alternatively, fixing a minor hole yourself allows you to save on the cost of labor. You'll only pay the cost of color-matched caulk and some basic supplies, adding up to around $15 to $40 (CAD 21 to CAD 55).

Depending on the cause of the damage, you may need additional repairs to prevent recurrence and keep your siding and walls in good condition. Damaged siding allows water to seep underneath, potentially leading to mold and water damage. Professionals generally charge around $2.50 to $20 (CAD 3.42 to CAD 27) per square foot to eliminate mold on the outside of your home and $2 to $12 (CAD 2.74 to CAD 16) per square foot to remediate water damage.

If you don't address leaky vinyl siding promptly, water can cause any underlying wood to rot. Repairing wood rot usually costs $5 to $11 (CAD 6.84 to CAD 15) per square foot. Most homeowners spend $100 to $2,000 (CAD 137 to CAD 2,738) in total to have a professional treat wood rot, and the cost depends on the size and severity of the problem.

Replacing vinyl siding usually costs between $4 and $5 (CAD 5.48 and CAD 6.84) per square foot or $130 to $1,000 (CAD 178 to CAD 1,369) per 100 square feet for materials, excluding installation labor. You may pay more for premium or decorative siding. For example, stone-effect vinyl siding can cost up to $10 (CAD 14) per square foot.

According to HomeGuide, professional siding installation costs between $2 and $6 (CAD 2.74 and CAD 8.21) per square foot, but charges vary depending on the cost of living in your city. Factor in an extra $0.70 to $2 (CAD 0.96 to CAD 2.74) per square foot to pay a pro to remove and dispose of the existing damaged siding.
