Deck Builder in Cedar Park, TX Decks Built for Hill Country Heat & Slopes

The ledger is the board that attaches the deck to your house. If it was installed without flashing, water gets trapped between the ledger and the rim joist, and both start to rot. Once the ledger weakens, the deck can pull away from the house, sometimes with no warning.

Builder decks from the 1990s and 2000s were often attached straight over hardboard siding with nails or a few lag screws and no metal flashing. For decades, May and October downpours have run behind those boards, and long dry spells in between kept the wood cracking open and letting more water in. Older Jollyville and Wells Branch decks are often worse because their ledgers were simply nailed on. By now, many of these connections have little holding strength left.

• Soft or spongy wood where the deck meets the house
• Dark staining or swollen siding behind the ledger
• A gap opening between the ledger and the wall
• Rusted nails or lag heads
• Deck bounces or sways when people gather
• Interior drywall stains on the other side of the wall

We see this most often on original decks in Buttercup Creek, Cypress Creek, Anderson Mill and Wells Branch, particularly where hardboard siding is still in place. Decks on the north side of a house, which stay damp in the shade, usually rot first.

Our fix: We remove the failed ledger and repair any rotted rim joist. Then we install proper flashing and through-bolts or structural screws, and add lateral load connectors that meet current code.

Footings move when the soil under them swells, shrinks or washes out. The deck tips, the framing racks out of square, and gaps open at the house. Doors to the deck may stick, and stairs can pull away from the landing.

Expansive Blackland Prairie clay from Round Rock to Pflugerville can rise and fall several inches between a wet spring and an August drought. Footings that are too shallow or undersized ride along with it. On the west side, contractors sometimes stop digging when they hit limestone and set posts on a thin layer of soil instead of anchoring into rock. Then a heavy storm washes that soil out from under the post.

• Deck surface visibly out of level
• Posts leaning or lifted off their bases
• Cracked or tilted concrete piers
• Stairs separating from the deck
• Gaps opening at the ledger in late summer
• Doors and gates sticking or not latching

Clay-related heave shows up most in Teravista, Falcon Pointe and eastern Leander. Washed-out footings on rock are common on the slopes in Jonestown, Lago Vista and Volente. Decks near creek greenbelts in Brushy Creek see both problems.

Our fix: Depending on the soil, we set new footings that go deeper into clay or anchor into the limestone. Then we re-level the posts and beams and reinforce or replace any racked framing.

A guardrail has to stop a fall. Over time, rails loosen as fasteners corrode and posts shrink. Many older decks were also built with rails that are too short or balusters spaced wider than 4 inches, so they never met the current safety standard.

Each wet-dry cycle swells and shrinks post bases, which slowly loosens the bolts. Posts that were notched to fit the rim joist, a common builder shortcut, crack under that repeated stress. Hail and straight-line winds add more wear. On elevated decks over sloped greenbelt lots, where the drop can easily be 6–10 feet, a weak rail is a real hazard, especially for families with young kids.

• Rail posts move when you push on them
• Balusters spaced 4 inches or wider
• Top rail lower than 36 inches
• Cracks at notched post bases
• Rusted or missing fasteners
• Stair handrails that wobble or stop short

We see loose rails all over the original sections of Cypress Creek and Twin Creeks. Lake Travis homes often have old wood rails that block the view, and owners want to replace them with cable or aluminum systems.

Our fix: We rebuild the post connections with structural hardware. Then we install code-compliant wood, composite, aluminum or cable railing systems at the correct height and spacing.

Ultraviolet light breaks down lignin in the surface of the wood. Boards turn gray, then check, split and splinter. Once a board cracks, it holds water, rots from the inside, and becomes rough or unsafe to walk on barefoot.

West-facing decks around here get several hours of direct, high-UV sun on summer afternoons, often at 100°F or hotter. Builder-grade pine with a cheap stain or none at all can gray in its first summer. Each sudden downpour followed by fast drying adds to the damage, which is why so many 15–20-year-old decks around Cedar Park are splintery and have cupped boards.

• Silver-gray, fuzzy wood surface
• Long cracks along the grain
• Splinters on bare feet
• Boards cupping or curling at edges
• Stain peeling or flaking in patches
• Screw heads popping above the surface

This is worst on west- and south-facing decks with no tree cover, which describes many newer lots in Leander, Liberty Hill and Santa Rita Ranch where the builder cleared the trees.

Our fix: If the framing is sound, we replace the damaged boards and then clean, brighten and seal the deck with a UV-stable finish. If too many boards are gone, we resurface it in composite or PVC.

Subterranean termites and decay fungi eat wood from the inside. Joists and posts can look fine on the surface while they lose most of their strength underneath, especially near the ground.

Central Texas has active subterranean termite colonies and enough warmth and humidity for fungi to thrive. Many older decks used lumber rated only for above-ground use on posts and low joists, sat right against soil or mulch, or had too little ventilation underneath. Ground-level decks over clay that stays wet after storms are especially likely to have problems.

• Mud tubes on posts or foundation
• Wood that sounds hollow when tapped
• Screwdriver sinks easily into joists
• Fungal growth or white mats under the deck
• Sagging spans between posts
• Frass or crumbling wood near grade

We find this most often on low decks in shady Anderson Mill, Jollyville and Brushy Creek yards with mature oaks. Fire ant mounds under the same decks tell us the ground there stays damp.

Our fix: We probe and map the damaged members and replace them with ground-contact-rated lumber. We also improve clearance and drainage so the new wood stays dry.

A deck you can't use from June to September isn't doing much for you. Dark composite boards can reach temperatures that are painful to stand on, and an uncovered deck facing west is basically unusable on summer afternoons.

Many homeowners picked dark composite colors from a showroom sample without knowing how they'd perform in Cedar Park's afternoon sun. Production-home backyards often have no mature trees, and HOA rules can limit what kind of shade structure you can add. The result is a deck that's hot to stand on and only gets used for a few months in spring and fall.

• Boards too hot to stand on barefoot
• Family avoids deck until evening
• Furniture and cushions fading fast
• Kids and pets can't play outside in summer
• Glare reflecting into the house
• Grill area unusable mid-day

This is common on new-construction lots in Crystal Falls, Travisso, Santa Rita Ranch and Teravista. Sun City residents in Georgetown often bring it up when they want a covered, low-step deck.

Our fix: We add a pergola, solid deck cover or covered patio. When it's time to resurface, we switch to lighter, heat-mitigating composite or PVC boards.

Falling branches, hail and straight-line winds can crack boards, dent aluminum rails, tear pergola roofs and knock framing out of alignment. Some of the damage is easy to spot. Other damage, like a cracked joist under the deck, isn't visible from above.

Winter Storm Uri in 2021 and the February 2023 ice storm brought heavy oak limbs down on decks across the area. Spring hail is common enough that the Austin–Round Rock market sees a lot of hail claims. Oak wilt also means tree trimming near a deck should be done at the right time of year. Many homeowners wait to trim, and then a storm brings the limbs down for them.

• Cracked or crushed boards
• Dented railing or pergola panels
• Bent joist hangers or brackets
• Posts knocked out of plumb
• Torn or holed deck cover roofing
• New wobble after a storm

We see this most under the mature live oaks in Anderson Mill, Brushy Creek and older Cedar Park. On exposed lake-view decks in Hudson Bend and Lakeway, wind damage is the bigger problem.

Our fix: We do a structural check, document the damage with photos for your insurance claim, and replace the damaged boards, rails, framing and cover materials.
