Before you expand or upgrade your outdoor living space, read below to learn the answers to the decking questions we get most often.
Your Decking Material Questions Answered
1. What type of decking material is best for our Midwest climate?
In Indiana, we experience hot summers and cold winters with occasional heavy snowfalls. So, it's important to choose a decking material that can withstand extreme temperature changes and moisture.
Popular choices for this region include composite decking, pressure-treated wood, and cedar.
Pressure-Treated Wood
This type of wood is chemically treated to resist rot, decay, and insect damage, making it a popular and affordable choice for Indiana homeowners. It can be stained or painted to match the aesthetic of your home.
All natural wood decks need regular maintenance.
A stained deck should be refinished every two to three years, while painted wood can last up to five if properly applied.
The key to getting a long-lasting finish with your stain is to remove the original finish completely before reapplying.
Sealer left on the wood may peal in the future, and can prevent the new finish from adhering. Follow all manufacturer instructions when applying new stain and sealer, or hire an experienced and reputable contractor to do the job for you.
Cedar Decking
This is another popular option as cedar is naturally resistant to rot and insect damage. It has a beautiful, natural look that can complement the surrounding environment. Keep in mind it does require regular maintenance to prevent it from fading or turning gray over time.
Composite Decking
This is a popular choice in the Midwest because it is durable, low-maintenance, and can withstand temperature changes and moisture well. Composite decking is made from a combination of wood fibers and plastic, which makes it resistant to rotting, warping, and cracking.
Although composite is very low maintenance, it still requires regular cleaning to look its best.
2. What is the best way to maintain and clean my deck?
Regular maintenance is crucial to keep your deck in good condition regardless of its material type.
Cleaning Pressure-Treated Decking
Clear the deck: Remove all furniture, grills, and other objects from the deck. Sweep or blow off any loose debris such as leaves, twigs, and dirt.
Prepare the cleaning solution: Mix a solution of warm water and mild detergent. You can also use a commercial deck cleaning solution, but be sure to follow the manufacturer's instructions.
Apply the cleaning solution: Using a garden sprayer, apply the cleaning solution to the deck, working in small sections. Allow the solution to sit for 10-15 minutes to penetrate the dirt and grime.
Scrub the deck: Using a stiff-bristled brush or power washer, scrub the deck in the direction of the wood grain. Be sure to work in small sections, rinsing the brush frequently.
Rinse the deck: Once you have scrubbed the entire deck, rinse it thoroughly with a garden hose or power washer. Be sure to rinse all the cleaning solution off the deck.
Allow the deck to dry: Allow the deck to dry completely before placing any furniture or objects back on it. This will prevent water from getting trapped underneath and causing mold or mildew.
Regularly cleaning your pressure-treated wood deck will help it last longer and maintain its appearance. It's recommended to clean your deck at least once a year.
Cleaning Cedar Decking
Clear the deck: Remove any furniture, planters, or other items from the deck surface.
Sweep the deck: Use a broom or leaf blower to remove any debris from the deck surface.
Mix the cleaning solution: Combine one part oxygen bleach with two parts warm water in a bucket. Avoid using chlorine bleach as it can damage the wood.
Apply the solution: Dip a stiff-bristle brush into the cleaning solution and apply it to the deck in small sections. Allow the solution to sit for 10-15 minutes.
Scrub the deck: Use the stiff-bristle brush to scrub the deck in the direction of the wood grain. Pay special attention to areas with stubborn stains or mildew.
Rinse the deck: Use a garden hose or pressure washer to rinse the deck thoroughly. Be sure to remove all the cleaning solution and any loosened dirt or debris.
Allow the deck to dry: Let the deck air-dry for at least 24 hours before using it.
Note: Avoid using a pressure washer on cedar decking as it can damage the wood. Also, be sure to wear protective gloves and eye wear when working with cleaning solutions.
Cleaning Composite Decking
Clear the deck: Remove any furniture, planters, or other items from the deck surface.
Sweep the deck: Use a broom or leaf blower to remove any debris from the deck surface.
Rinse the deck: Use a garden hose to rinse the deck surface thoroughly. This will help remove any loose debris and prepare the deck for cleaning.
Apply the cleaner: TimberTech recommends using a deck cleaner specifically designed for composite decking. Apply the cleaner with a soft-bristle brush or sprayer, following the manufacturer's instructions.
Scrub the deck: Use a soft-bristle brush to scrub the deck surface in a circular motion. This will help remove any dirt, stains, or mildew that may have accumulated on the deck.
Rinse the deck: After scrubbing, rinse the deck surface thoroughly with a garden hose. Be sure to remove all the cleaning solution and any loosened dirt or debris.
Allow the deck to dry: Let the deck air-dry for at least 24 hours before using it.
Note: Avoid using pressure washers or abrasive cleaners on composite decking as they can damage the surface. Also, be sure to check the manufacturer's guidelines for any specific cleaning recommendations.
3. How do I prevent my pressure treated deck from warping?
Use good quality lumber: Start with high-quality, straight lumber for your deck. Choose lumber that is free from knots and other defects that could weaken the wood and cause it to warp.
Seal the wood: Apply a water-repellent sealer to the wood as soon as possible after installation. This will help to protect the wood from moisture damage and prevent warping.
Use proper spacing: When installing the deck boards, make sure to leave adequate spacing between the boards to allow for expansion and contraction due to changes in temperature and humidity. Check with your local building codes for recommended spacing requirements.
Install the boards properly: Make sure the deck boards are installed with the crown side up. The crown is the slightly curved side of the board, and installing it with the crown up will help prevent warping.
Maintain the deck: Regular maintenance, such as cleaning and sealing, can help prevent moisture damage and keep the wood from warping over time.
Provide adequate ventilation: Make sure there is adequate ventilation underneath the deck to allow for air flow. This will help prevent moisture buildup and reduce the risk of warping.
Tips for Preventing Warping with Cedar
Use proper spacing: Like with pressure-treated lumber decking, proper spacing between the deck boards is crucial to allow for expansion and contraction due to changes in temperature and humidity. Check with your local building codes for recommended spacing requirements.
Seal the wood: While cedar is naturally resistant to decay and insects, sealing the wood can help to protect it from moisture damage and prevent warping. Use a water-repellent sealer designed for cedar.
Use stainless steel screws: When fastening the deck boards to the joists, use stainless steel screws instead of nails. Screws provide a stronger connection and are less likely to loosen or pull out over time.
Maintain the deck: Regular maintenance, such as cleaning and re-sealing, can help prevent moisture damage and keep the wood from warping over time.
Provide adequate ventilation: Ensure that there is adequate ventilation underneath the deck to allow for air flow. This will help prevent moisture buildup and reduce the risk of warping.
Avoid direct sun exposure: Cedar decking can warp due to prolonged exposure to direct sunlight. Consider using shade sails or umbrellas to provide some shade and reduce the risk of warping.
4. What is the expected lifespan of a deck?
The lifespan of a deck varies depending on the quality of material used, design of the deck, maintenance, and weather conditions.
Cedar, on the other hand, typically lasts around 15-20 years with proper maintenance. Additionally, cedar is a more sustainable and eco-friendly option than pressure-treated lumber, which contains chemicals that can be harmful to the environment.
Pressure-treated lumber has a longer lifespan than cedar, usually lasting around 20-25 years with proper maintenance.
Composite decking can last upwards of 25-30 years. It's resistant to rot, insects, and moisture damage because it is made from a combination of wood fibers and plastic.
While composite decking may be more expensive than wood decks initially, the longer lifespan and low maintenance requirements can make it a more cost-effective option over time. Additionally, composite decking is a more eco-friendly option than pressure-treated lumber, which contains chemicals that can be harmful to the environment.
Overall, the longer lifespan and low maintenance requirements make composite decking an attractive option for homeowners looking to build a durable and long-lasting deck.
5. Can I install a deck myself or should I hire a professional?
While it's possible to install a deck yourself, it's recommended to hire a professional contractor who has experience and knowledge in deck installation. A professional can ensure that the deck is properly installed, meets local building codes and regulations, and is safe and secure for use.
