Heat, Humidity, and Your Deck

How Heat and Humidity Can Damage Your Deck

Damaged Boards

Here you can see long term damage that can be done by weather.

Here is the Midwest we are used to crazy weather patterns that can change at the drop of a hat, but our decks? Not so much. Summer heat and humidity can really do a number to your deck, especially if your deck is untreated or unsealed. Composite decks have their own challenges as well. 

We always recommend putting a protective layer on your deck, by staining or sealing it with a weather protective layer. This way your deck will have more longevity and be able to stand up to the elements. Or if you want you can negate the whole process by having a Trex Composite deck.

Heat Exposure

Damage can be done over time from heat, sun, and rain exposure. When it’s hot out wood will shrink and dry out, which make it more absorbent to rain and liquids. This will absorb into untreated wood and cause swelling and buckling. This cycle of shrinking and swelling will cause wood to warp and buckle and can pull nails out from joints.

To prevent this we recommend putting a sealant on your deck every 1-2 years for the best result. This will help keep wood exposed to the elements dry and will minimize the warping.

Mildew and Mold

In the Midwest our humidity levels can get overwhelming, and this can affect your deck. Mold and mildew spores are constantly in the air, and normally aren’t too much of a problem. When rain and high humidity get into the mix, this creates the perfect conditions for them to grow in the nooks and crannies of your deck. When this growth happens you will typically see it as discolorations or stains on your deck. These stains generally look black, brown or green and can spread and grow in the right conditions. This causes what is commonly referred to as mildew staining.

Once the stain has set into your deck you will have to either use a fungicide that is specially formulated for decks, or use a 1:3 ratio Bleach to water solution (vinegar can also be substituted for the bleach if chemicals are a concern) to clean your deck. Follow this wash by sanding and sealing your deck after it has had a good week to dry out in the sun.

Wood Deck Cleaning Tips

The summertime brings lots of outdoor events, but also warm, dry weather. Now is a great time to do an inspection around your wood deck. Pay close attention to any planters, downspouts, or anything close to sources of water. When inspecting your deck:

  1. Look around for signs of rotting-this includes the stairs, the perimeter post, and on top/underneath the deck. Grab a flat-blade screwdriver and gently push it into the area that’s being inspected. If you can push your screwdriver in about a quarter-inch or more, you most likely have rot.Wood Deck care
  2. Do an inspection of the ledger-pay close attention to this, as this is one of the most important pieces of framing because it attaches the wood deck to the house. If a ledger is damaged or broken, there’s a huge possibility that your deck will collapse. Your deck’s ledger should be attached with not just nails, but lag screws.
  3. Be sure to check the remaining posts, beams, and joists-if you notice that any of the hardware is rusted, please make sure to get them replaced as soon as possible.
  4. Look for rotted decking boards or cracks-not all cracks are threatening, BUT if you find any damage, replace the piece. If you choose to not deal with it now, overtime it’ll get worse. It’s better to be safe than sorry.
  5. Inspect the railing-give your railing a good shake to make sure that nothing is loose. If you notice that your railing is damaged or loose, simply remove the fastener and fill in the crack with an exterior-grade adhesive.

Taking care of your wood deck will help it to look brand new again. Before making any repairs to your wood deck, be sure to properly wash it with a pressure washer to remove any wood fibers or dirt from it.
