Outdoor decks take a lot of abuse. They are exposed to extreme weather conditions and harsh UV rays all year long. Replacing an occasional warped board or repairing a loose railing is an expected part of deck maintenance. However, there may come a time when the entire deck needs to be replaced.
A Matter of Safety
You may feel your deck is still serviceable even with a few wobbly boards, but it could be more of a safety hazard than you realize. You know better than to trust the middle board on that last step, but will your guests be aware?
A faulty deck can cause many types of injuries, from a splinter or scratch to a sprained ankle. If repair issues are serious enough, they could even cause a total deck collapse. Addressing the warning signs of a failing deck keeps your property value up and ensures your deck is safe for the entire family.
8 Signs It’s Time for Deck Replacement
Some damage is easy to see, but some deck problems can go undetected until they cause serious structural problems. If you’re experiencing one or more of these issues, speak with an experienced contractor to learn more about building a new custom deck.
1. Sagging
Sagging boards or sections are easy to see and feel. Decking boards should feel sturdy and not move when you walk across them. Sagging or “bouncy” boards can be an indication of structural problems that are beyond repair. Problems with posts, joists, or footings can cause parts of the deck to sag or shift.
2. Insect or Rodent Damage
Several types of insects and rodents can damage a deck, including carpenter bees, termites, carpenter ants, mice, and rats. Signs of an infestation include the appearance of droppings, small burrow holes, and bite marks. If your deck has a hollow sound when you walk on it, an infestation may be the problem.
3. Damaged Decking
Some minor surface damage is normal, but deep cracks or broken deck boards are signs that the wood is aging and can no longer support the weight of the deck.
If you spot the damage early, replacing the compromised boards may be enough to keep the deck functional. However, damaged boards can also indicate bigger problems, such as structural damage. Have a pro inspect your deck to determine the best solution.
4. Algae, Mold, or Mildew
Excess moisture in the wood can result in the growth of algae, mold, or mildew. Fungi and algae may be a sign of rotting wood. Look under the deck, especially in areas that are naturally shady and damp. Removing the mold is the first step. Check for wood that smells or looks like it’s rotting or that feels soft.
Replacing rotted boards isn’t always enough. Even a few bad boards could weaken the entire deck.
5. Damaged Ledger Board
The board that connects the deck to the house is called the ledger board. It is secured with screws or bolts. The ledger board is one of the most important structural parts of your deck. If it becomes damaged or loose, the structure is at risk of collapsing.
Check to make sure the ledger board is secure with no loose screws and is not slanted or cracked.
6. Slanted Posts
Deck posts provide crucial structural support to the entire expanse. Even one slanting post can lead to a collapse. A professional deck contractor may be able to repair a deck post depending on the cause and severity of the problem, but a slanted post may be telling you it’s time to replace your old deck.
7. Loose Railings
Loose railings are not only a safety hazard, but they could also be a sign of rotting boards or failing fasteners.
8. Outdated Construction Standards
If your deck is more than 15 years old, it may not meet current building codes. If this is the case, no experienced contractor would agree to make repairs.
Safety and building standards change over time. If your older deck is showing its age, updating to a new cedar or composite deck will ensure safe usage for the next 15 years and may also increase your home’s value.
Don’t Take a Chance — Have Your Deck Inspected
Regular deck maintenance can prevent the kinds of damage that lead to needing a replacement. Cleaning, resealing, and repairing damage as soon as possible will extend the lifespan of your deck. However, even the most well-maintained decks will have to be replaced at some point.
