Step One: Check for Damage

The first step in learning how to restore your deck for spring is to check for damage. Winter can be very hard on outdoor structures, and it’s important to assess the deck’s condition before scheduling any backyard bashes. It’s best to start with a bottom-up inspection.

Inspect the Support Posts

Get a good look at the support posts. They should sit on top of poured concrete footings, and they should be rot- and moisture-free. Tap the bottom of the support post with a hammer and take note of whether it feels solid or soft. Soft support posts could be wicking up moisture from the ground, and that can cause them to rot.

You’ll want to check any hardware connecting the support posts to the support beams, as well. Also, check the wood around for any obvious points of rot or damage.

Inspect the Joists

The joists make up the main structure of the deck. They typically run from the house to the edge of the deck, perpendicular to the deck boards above.

Joists are susceptible to rot, insect damage, or even cracking and splintering due to age. If they rot, the damage is typically on the top few inches of the board. Carpenter ants and termites will attack wood with high moisture content, so be sure to check parts of the deck that might not dry as quickly as the rest. Also, look for almost perfectly round holes bored into the wood—a sure sign of carpenter bee damage.

Get a Look at the Deck Boards

One of the most common issues to look for on a deck is deck board damage. Again, this can be from rot, bugs, or age. It can also be the result of the sun’s damaging rays breaking down the wood’s fiber over time.

Be on the lookout for any areas that feel spongy or bouncy. Also, look for discoloration, flaking finish, or excessive splintering. Pay extra attention to the boards directly under the eaves of the home as they often collect water from rain or snow as it falls. Replacing deck boards is not a super complicated process, and should be done promptly if you find one that needs it, to avoid further damage and potential injury.

Check the Railings

Whether they’re vinyl, wood, metal, or a combination, railings need to be sturdy and trustworthy. If not, you’ll never feel at ease having folks over, swapping stories and soaking up the sunshine while leaning against them.

Start underneath the deck, if possible. Check each post for loose hardware, rotting, insect damage, or compromised strength. Above the deck, check the posts for signs of rot, excessive moisture, cracking, splintering, or broken or badly worn hardware. Any of these can result in a weak spot where handrails might be most likely to fail.

Step Two: Replace Damaged Boards and Hardware

Trying to ignore damaged boards is not worth the risk, and replacing deck boards is a key part of deck restoration. Damaged or rotten boards can give way underfoot, or separate from the structure, compromising the safety of the entire deck. Replacing deck boards takes just a few steps, and it’s best to start with the same bottom-up approach.

Materials:

• 6×6 posts
• 4×4 posts
• 2×8, 2×10, or 2×12 pressure treated lumber in necessary lengths
• Deck boards (pressure-treated or composite)
• Replacement spindles
• Exterior grade deck screws
• 9-gauge exterior joist hanger nails
• Joist hangers
• Hurricane ties
• Railing brackets
• Galvanized carriage bolts, washes, and nuts

Replace Posts First

Start by replacing any damaged support posts, as any deck is only as good as its foundation. Be sure to prop the deck up with temporary supports before removing the damaged post. This can typically be a spare 6×6 post positioned carefully near the existing post. Also, work on one post at a time for safety’s sake.

1. Detach the post from the beam by removing the nails, metal brackets, or bolts holding the joint together.

2. Remove the nails or screws from the bracket holding the support post to the footing.

3. Carefully remove the post, ensuring the temporary support post is adequately holding the beam.

4. Use the old post as a template for the new one. Transfer notches and cut-outs from the old post to the new one, and cut it to length.

5. Slide the new post into place. It’s typically easiest to install the base of the post before the top. If persuasion with a sledgehammer is necessary, be sure to use a piece of scrap wood as a sacrificial tapping block to prevent damaging the new post.

6. Attach the post using new hardware and brackets, if necessary.

7. Carefully remove the temporary support and repeat at the next post, if necessary.

Handle Joist Damage

Joist damage can be a serious problem, and while it may be a bit of work, the following steps will help.

1. Locate the joist in question from the top of the deck.

2. Remove all the screws connecting the deck boards to the damaged joist. If necessary, remove the railing to access screws underneath. Cut any screws that don’t come out willingly by sliding a reciprocating saw blade between the joist and the bottom of the deck board.

3. Remove the rim joist (the outer joist that spans across the ends of all the joists) as well as any bolts connecting the railing post to the joists.

4. Install a scrap piece of wood spanning from the joists on either side of the damaged joist. Be sure to use two or three screws driven up through the scrap piece and into the joists on each end.

5. Remove the hurricane tie connecting the joist to any beams.

6. Carefully remove the joist hanger. If all the screws are removed from the deck boards, the joist should be loose, but probably sandwiched between the deck’s upper surface and the support beam.

7. Strike the bottom of the joist in one direction and the top in the opposite direction until it falls over. Slide it out the front of the deck.

Note: Joists can be very heavy, especially if wet and rotten. Be very careful and enlist help if necessary.

8. Use this joist as a template for the new one. Either place the old joist on top of the new one and mark it to length, or measure and mark the new joist according to the old joist’s dimensions.

9. Slide the new joist over the beam and underneath the deck, ensuring that it rests on the piece of scrap attached to the two neighboring joists.

10. Stand the joist up by twisting and striking the top and bottom of the board in opposite directions. This may require help, and be sure to use scrap wood as a sacrificial striking surface whenever possible. Adjust the joist’s positioning so it aligns with the previous joist’s location.

11. Use the sacrificial board and a small sledgehammer to tap the joist up against the ledger board. Install a new joist hanger and hurricane tie using the joist hanger nails to hold the joist in place.

12. Reinstall the rim joist and screw through the deck boards and into the new joist with exterior grade screws.

Sturdy Those Railings

Sturdy deck railings are vital to keeping folks safe during get-togethers, gatherings, and cookouts. Luckily, they’re typically fairly easy to prepare for spring.

1. Remove any damaged railing sections from the posts. This will include sections with broken brackets, spindles, rails, or other components. In most cases, these are impossible to repair in place, so it’s best to remove them completely.

2. Start by replacing any broken or damaged spindles. For wood spindles, remove the screws holding them into the top and bottom rails. For metal spindles, it may be possible to simply separate the top and bottom railing as these spindles typically sit inside brackets or over top of small pegs. For vinyl railings, it may be necessary to replace the entire railing.

3. If the posts need to be replaced, do it before replacing the railings. Remove the carriage bolts and nuts attaching them to the deck’s framing. Remove the posts and use them as a template for cutting the new posts. Reinstall them and bolt them back into place.

Note: If the deck boards around the post need replacing, it may be worth waiting until that part of the process is complete before reinstalling posts or railings.

4. Reinstall the railings by reusing the old brackets or by replacing them with new brackets. Attach the brackets to the railings first before screwing them to the railings.

Replace the Deck Boards

Deck boards take a beating, and they’re often the first deck component to fail. This is a common issue, and thankfully replacing deck boards is typically straightforward.

1. Identify the damaged deck board and remove it from the deck. There should be at least two screws holding the deck board down at each joist location. Remove the screws and the board.

Note: Be sure that any guests, children, or pets don’t walk on the deck while the board is removed to avoid anyone accidentally stepping in the gap and getting hurt.

2. Use the old deck board as a template for the new board. Lay the old board on top of the new one and use a pencil to mark the new board to length. Cut the new board to length.

Note: If the old board is damaged and breaks during removal, use a tape measure to determine the length of the new board. It’s also possible to install a full-length board and then cut it to length.

3. Place the new board perfectly parallel to the gap left by the old board. Mark the locations of the joists on the new board by aligning a speed square with the center of the joist and drawing a light pencil mark across the board.

4. Pre-drill two holes along each pencil mark. The holes should be approximately 1 inch from the edge of the board, but some composite decking manufacturers may have more specific placements.

5. Place the board in the gap and drive a screw through each of the pre-drilled holes. Do not overdrive the screw so far that the head creates a deep depression in the top of the deck board or it will collect water.

6. If the board was intentionally left long, use a circular saw to trim it to length.

Step Three: Pressure Wash Your Deck

For the lucky ones, the path to getting a deck ready for spring may only require a quick pressure washing. This doesn’t require a lot of tools, and the steps are pretty straightforward. Very often, small, affordable electric-powered pressure washers are more than capable of handling deck jobs. For folks who need a bit more power, consider renting a gas-powered model.

Power washing is a great thing to do before restaining a deck or refinishing a deck, since you’ll want to remove all the dirt and grime from the winter before adding a coat of anything protective.

Here are the steps to follow to get it done:

1. Use the lowest possible pressure that will get the job done. Usually, this is around 500 to 600 PSI (for soft woods like pine and cedar), but some decks might require more pressure. Never exceed 1,200 PSI or you’ll likely end up replacing more boards than you clean.

2. Use a 40- to 60-degree fan tip, as either will cover a wide enough area to work quickly, but still be concentrated enough to be effective.

3. Start in one corner of the deck and work across the deck boards. Point the wand up slightly before squeezing the trigger. Once the spray is up to pressure, lower the tip of the wand to within 6 to 10 inches of the deck’s surface.

4. Use short, sweeping motions, keeping the fan pattern perpendicular to the boards, and maintaining a consistent distance from the deck. Slightly overlap each pass to ensure there aren’t any noticeable lap marks. Continue across the entire deck surface, including the railings and spindles, if necessary.

5. After pressure washing, let the deck dry for a few hours in sunlight. Once dry to the touch, give the deck surface a light sanding with 100-grit sandpaper. This will knock down any fibers that might be standing from the pressure washing, creating a smoother surface that will accept stain or paint better. Be sure to sweep off the deck after sanding.

Note: Pressure washing may reveal damaged deck boards and broken spindles. If this occurs, refer back to the steps earlier in this guide.

Step Four: Stain and Seal Your Deck

One of the last steps necessary when preparing a deck for spring is staining or sealing. This step is important because it will protect all the hard work you just put in repairing deck boards and railings. If the process for how to restain a deck sounds complicated, we assure you it’s not. The trickiest part is actually timing the restaining correctly after your pressure washing.

Please note that if it was necessary to replace any wood components with new lumber, it’s important to wait for the wood to dry completely before staining or sealing. If it’s a simple pressure washing, be sure to wait a few days. In either case, wet wood will prevent stain or sealer from penetrating the wood, so make sure you give ample time before completing a deck refinishing.

Materials:

• Paint roller
• Paint tray
• Paintbrush
• Paint sprayer (optional)
• Stain or sealer

1. Choose the stain or sealer. Oil-based stains and sealers often penetrate the wood better than water-based products, but they take longer to dry and they’re harder to clean up. Water-based products are easier to apply and clean up, and their fumes are generally less noxious.

2. Make sure the deck is clean and dry. Pressure washing the deck and then waiting a few days for it to dry is the best bet. Sweep or blow any debris off the deck.

3. When refinishing a deck, you’ll want to work in stages. Stain the railings first, using the paintbrush to work the stain or sealer into all the nooks and crannies. Working in small areas, overlap the previous strokes, and maintain a wet edge.

4. With railings done, move to the deck’s surface. Work in small areas, approximately 3-feet-wide by 3-feet-long. Overlap the previous passes, being sure to maintain a wet roller to prevent lap marks.

Note: during a deck refinish, take care not to stain yourself into a corner. Generally speaking, it makes sense to start on the end of the deck furthest from the stairs, and then work toward them, staining one stair at a time on the way down.

4. For water-based stains, wait 24 hours before walking on the deck, and 48 hours before regular use. For oil-based stains, be sure to wait at least 72 hours before using the deck at all. After the stain is done drying, the bulk of the work for your deck restoration is done, and now you can move onto the most fun part.
