How to Maintain Your Deck During a Colorado Springs Summer

A deck in Colorado Springs ages differently than one in most of the country. The combination of high-elevation UV exposure, low humidity that dries wood out faster than it can equilibrate, afternoon thunderstorms that can deposit hail with almost no warning, and temperatures that swing 40 degrees between an afternoon high and a morning low puts a lot of mechanical and environmental stress on wood and its finish over a single summer.

The good news is that most of this damage is manageable with the right maintenance at the right time. Here is how to approach deck care through a Colorado Springs summer.

Start With an Honest Inspection

Before anything else, walk your deck slowly and systematically. What you find in this early-season inspection determines what the rest of your summer maintenance looks like.

Start at the ledger board, the horizontal member where the deck attaches to your house. This is the most structurally critical connection on the deck and one of the most vulnerable to moisture damage. Look for any separation between the ledger and the house, any signs of rot or discoloration in the wood, and any gaps in the flashing above the ledger that might be letting water in behind it.

Move to the posts. Check each one at ground level by pressing firmly from the side. A post that moves at all has a compromised footing or a rotted base. Both need to be addressed before the deck is used for the season, because a post failure under load is a serious safety risk.

Walk across every board and pay attention to what you feel underfoot. Boards that bounce, feel soft, or have any give where they should be rigid have deteriorated past the point where surface treatment will help. They need to be replaced. Also check for boards that have split along the grain, cupped significantly, or have raised fasteners — all signs of wood that has been through repeated moisture and drying cycles without adequate protection.

Finally, check the railings. Push on them laterally and vertically. Railing connections loosen over time, especially at post brackets, and a railing that fails when someone leans against it is a fall hazard.

Clean Before You Apply Anything

Sealant or stain applied over a dirty surface bonds to the dirt, not the wood. The result is a finish that peels or flakes within a season instead of lasting two or three years. Cleaning the deck properly before refinishing is the step that most DIY attempts skip or underdo, and it is the single biggest reason backyard deck finishes fail prematurely.

Start by sweeping all debris off the surface and clearing out anything that has accumulated between boards. Pine needles, cottonwood fluff, and leaf debris hold moisture against the wood and need to be cleared out completely.

For the surface itself, use a deck cleaner formulated for the species of wood you have. Pressure washing can work, but the settings matter. Too much pressure raises the grain of the wood and can drive water into the surface in ways that work against you. Keep the nozzle moving, keep the tip at least 12 inches from the surface, and use a fan tip rather than a zero-degree tip. Work with the grain, not across it.

Allow the deck to dry completely before applying any product. In Colorado Springs’ dry climate this often happens within 24 to 48 hours after cleaning, but thicker lumber like 5/4 decking can hold moisture longer than it appears to from the surface.

Choosing the Right Product for Colorado’s Climate

Not all deck stains and sealants perform the same way in Colorado. The high UV index at elevation degrades finishes faster than at sea level, which is why products that hold up well in coastal or Midwest climates may show significant fading or breakdown here in a single season.

Look for products rated for UV resistance, specifically formulated for exterior wood, and appropriate for your wood species. Oil-based penetrating stains tend to perform well on cedar and pressure-treated pine in Colorado’s dry climate because they penetrate the wood fiber rather than forming a film on top, which means they do not peel — they simply wear away and can be reapplied without stripping. Film-forming products like paints and solid-color stains can look good initially but require more preparation on each reapplication because they must be stripped before recoating.

For composite decking, skip stain entirely and follow the manufacturer’s maintenance guidance, which is usually limited to cleaning. Composite materials do not absorb sealants the way wood does and applying them can trap moisture and cause surface problems.

What Hail Does to a Deck and What to Do About It

A significant hail event in the middle of summer can do visible surface damage to wood decking. Large hailstones leave impact marks and dents in softwood like cedar or pine. They can also drive small debris into the wood surface, create micro-fractures in the grain, and strip away fresh sealant that was applied earlier in the season.

After any significant hail event, do a quick walkthrough of your deck. Look for new impact marks, any boards that split or cracked under impact, and any damaged railing or post cap components. Clear off any debris that collected on the surface and in the gaps between boards promptly, because wet debris sitting against the wood extends moisture exposure well beyond the storm itself.

If the deck was recently sealed and the hail was significant, check the water-bead test again after the surface dries. Pour a small amount of water on a board. If it soaks in rather than beading, the sealant layer took enough damage that a fresh application is worth doing.

Ongoing Care Through the Season

Summer deck maintenance is not a one-time event. A few habits through the season keep small issues from becoming larger ones by fall.

Sweep the deck regularly and keep gaps between boards clear. Debris in the gaps retains moisture and can cause boards to rot from underneath even if the top surface looks fine. Move furniture periodically if it stays in fixed positions, because furniture feet that sit in the same spot all summer create soft spots in the finish from the combination of trapped moisture and UV blocking.

If you have planters or pots on the deck, keep them elevated on pot feet or risers. A planter sitting directly on the deck boards traps moisture and concentrates weight in a small area, both of which shorten the life of the wood under it significantly.

Check any areas where vertical surfaces meet the deck surface — post bases, railing bottom plates, stair stringers — periodically through the season. These transition points are where moisture is most likely to collect and where rot starts.

When the Job Is Bigger Than a Weekend Project

Some deck maintenance is well within homeowner territory. Cleaning, resealing, replacing an individual board, and tightening loose railing hardware are reasonable DIY projects with the right materials and a weekend afternoon.

Post resets, ledger repairs, structural section replacement, and anything involving the deck’s connection to the house are different. These repairs require understanding how the deck is built, what hardware and fastener specifications are appropriate, and how to ensure the work holds up to Colorado’s load conditions, including snow loads in winter that can be significant at Colorado Springs elevations.

Jay P’s Handyman Service handles deck installation and repair in Colorado Springs for situations where the scope goes beyond weekend DIY. Whether it is replacing damaged boards after a hail event, resetting a post with a compromised footing, or rebuilding a railing section to current safety standards, the work is done correctly so the deck holds up through more than one season.
