Maintenance and Repairs


Painted deck

The cost of painting a deck can be between $1.50 to $3.50 per square foot.

Painting your deck is essential to not only enhance its appearance but also to protect it from the elements. Deck paint can help prevent moisture from seeping into the wood, reducing the chances of rot and damage. Generally, it is recommended to repaint your deck every 2-3 years.


The average cost to install or replace deck flashing ranges from $5 to $10 per linear foot, depending on the material and labor needed for the job.

Flashing is a critical component for maintaining the structural integrity of your deck. It is installed at the attachment points between the deck and the house and helps divert water away from your home.

Over time, flashing may wear out or become damaged, increasing the risk of moisture intrusion and damage to your deck and home.

To inspect your deck flashing, check for signs of wear and tear, such as rust or corrosion.

Deck Repairs

Regular maintenance can help prolong the life of your existing deck, but some repairs may still be needed.

Common deck repairs include replacing damaged boards, fixing loose nails or screws, and repairing damaged railings.
