Railings
The deck guard that wobbles when the kids lean against it. The porch baluster that came loose three winters ago and the homeowner has been meaning to fix. The cedar top rail that finally rotted through at the post and a hand went through it. The cable run that was tight on install day in 2019 and now sags low enough to fail the 4-inch sphere rule. The stair handrail that was glued to the wall and pulled out the first time a guest grabbed it on the way down. Railings is the trade for every guard, baluster, and handrail outside (and the interior stair rails where a fall is a real risk) — five material systems with very different price floors, very different maintenance profiles, and one shared code reference. Every system Handis builds meets IRC R312 — 36-inch minimum guard height (42 inches in some Seattle-area jurisdictions where the deck sits more than 30 inches above grade), the 200-pound concentrated load capacity at the top rail, and the 4-inch sphere rule for infill. Pure carpentry — no licensed sub is required for the railing itself. From $2,500 for a small pressure-treated wood replacement to $16,000 for a frameless tempered laminated glass run on a view deck.
Systems
What Railings Covers
Railings is the carpentry trade for every guard, baluster, top rail, and handrail on a residential deck, porch, balcony, or stair. Five material systems Handis installs — wood (pressure-treated, cedar, mahogany), cable (316 stainless for the salt air and rain), glass (tempered laminated per IBC 2407), aluminum (powder-coated systems from AFCO, Westbury, Trex Signature), and composite (TimberTech Impression Rail, Trex Transcend, Fiberon). Each system gets its own page with the pricing, the install steps, and the maintenance schedule. Every install meets IRC R312 — 36-inch minimum guard height (42 inches where local amendments apply for decks more than 30 inches above grade), the 200-pound concentrated load at the top rail, and the 4-inch sphere rule for the infill openings. Handis self-performs the full scope; no licensed plumbing or electrical sub is required for pure railing carpentry.
Wood Railing
Pressure-treated, cedar, Douglas fir, or mahogany. Turned 2x2 balusters or square pickets, a 2x4 or 2x6 top rail, 4x4 or 6x6 posts. The lowest-cost material and the highest maintenance — pressure-treated needs a sealer every two to three years, cedar silvers if left untreated (a deliberate choice for some) or needs an annual oil-based stain to keep the warm tone, mahogany asks for a marine-grade finish to hold up in the rain. The right pick for a budget-led replacement, a traditional porch profile, or a craftsman or farmhouse aesthetic. From $2,500 for a 25-linear-foot pressure-treated replacement to $7,000 for a clear cedar or mahogany run with shaped balusters.
Wood Railing — pressure-treated, cedar, fir, mahogany; traditional profile
Cable Railing
Stainless 316 marine-grade cable strung horizontally between posts, tensioned tight enough that the cable spacing passes the 4-inch sphere rule (typically 3-inch on-center spacing). Posts can be aluminum, stainless, powder-coated steel, or wood with through-post tensioner hardware. The cleanest sight-line of any system after frameless glass — a view-deck favorite for Lake Washington, Puget Sound, and Cascade-facing properties. Cables require annual re-tensioning for the first two to three years (the cable creeps under load and slackens) and inspection every spring; we walk that schedule with you. Vendors we install — Atlantis Rail, Feeney CableRail, Ultra-tec. From $4,500 for a basic aluminum-post system on a small deck to $12,000 for a powder-coated steel-post premium system on a long view run.
Cable Railing — 316 stainless, view-deck sight-line, annual re-tensioning schedule
Glass Railing
Tempered laminated glass per IBC 2407 (laminated is required for guard use — if both lites break, the interlayer holds the assembly together long enough to prevent a fall). Three mounting styles — framed (top and bottom rail, picket-style vertical posts), frameless base-channel (continuous channel mounted to the deck framing), or frameless standoff (point-loaded stainless standoffs into the deck framing or fascia). The strongest sight-line, the highest cost, and the highest maintenance (glass shows every water spot, every rain mark, every dog nose-print — plan on a monthly squeegee). Vendors — C.R. Laurence, Crystalia, Q-railing. From $6,000 for a framed system on a small balcony to $16,000 for a frameless standoff system on a long view run.
Glass Railing — tempered laminated to IBC 2407, framed or frameless
Aluminum Railing
Powder-coated aluminum systems from major fabricators (AFCO Aluminum, Westbury, Trex Signature, Fortress, Key-Link). Square or round pickets, sleek top and bottom rails, color-through powder coat that does not flake or peel like paint. The lowest-maintenance material of any railing system — no painting, no staining, no annual sealer, no cable re-tensioning. A clear runner-up on price between wood and the premium materials. Color options are typically black, bronze, white, and a few textured premium colors. From $3,500 for a standard black 25-linear-foot run to $9,000 for a longer premium-color textured system.
Aluminum Railing — powder-coated, no maintenance, AFCO and Westbury
Composite Railing
Composite top rail and balusters in PVC or composite material from the same manufacturers as composite decking — TimberTech Impression Rail, Trex Transcend, Fiberon Symmetry. The right pairing if the deck itself is composite (or about to be), so the railing tone matches the decking line out of the box. 25-year warranty typical from each manufacturer. Aluminum balusters are commonly mixed with composite top and bottom rails (the strength of aluminum where the load actually concentrates, the composite color match where it shows). From $3,500 for a standard composite system to $9,000 for a top-tier Trex Signature with aluminum balusters and color-matched posts.
Composite Railing — TimberTech, Trex, Fiberon; deck-matched
Railings Pricing
Final pricing depends on the linear footage, the material selected, the post style (wood, aluminum, steel, stainless), any returns or stair runs, and whether the existing framing meets the 200-pound load requirement (older decks sometimes need post blocking added before the railing install). Each material page lists detailed pricing for that system. Request a free in-home estimate for an accurate quote against your actual deck and railing run.

Why Seattle Homeowners Book Handis for Railings
A failing deck railing is not a cosmetic problem. It is the only thing between someone and a fall, and IRC R312 wrote the 36-inch height and the 200-pound load capacity into code because falls from residential decks are the most common single source of serious deck injury in the US — the CPSC has tracked it for decades. The deck guard that wobbles when leaned on, the baluster that pulls loose in a hand, the cable run that sags wide enough that a toddler can put a head through it — every one of those is a liability that should be on the next-fix list, not the someday list. Handis carpenters install every system to code, document the post connections in the photos we send at closeout, and tell you on the call which material is the right pick for the actual use case (kids and dogs, view deck, low-maintenance retirement, deliberate craftsman wood profile).
Built to IRC R312 — 36-inch height, 200-pound load, 4-inch sphere
Every guard we install meets the residential code — 36-inch minimum guard height (42 inches in jurisdictions like Bellevue and parts of Seattle DCI where the deck sits more than 30 inches above grade — we check the AHJ before the quote), the 200-pound concentrated load capacity at the top rail (post spacing and through-bolt schedule are sized for it), and the 4-inch sphere rule for infill (no opening wide enough that a 4-inch sphere passes — sized by manufacturer for aluminum and composite systems, set by cable tension and on-center spacing for cable, set by glass panel size for glass). We document the post connections with photos at closeout.
Honest material pick — what the railing is actually for
We will tell you on the call which material fits the use case. Wood for a craftsman or farmhouse aesthetic where the homeowner wants to refinish every few years. Cable or glass for a view deck where the sight-line is the whole reason for the deck. Aluminum or composite for a low-maintenance install where the homeowner does not want to refinish anything. We do not push the highest-priced material when the use case fits a lower-cost option — and we will be straight about the maintenance schedule (cable re-tensioning, wood sealer, glass squeegee) before you commit.
Post connections done right — through-bolted, blocked, no lag-screws into rim
The single most common deck-railing failure pattern is a post connected with lag screws into the deck rim joist alone — the lags pull out over time as the wood checks and seasons, and the railing goes wobbly. Code requires posts connected to the framing so the assembly carries the 200-pound load at the top rail; that means through-bolts with washers (not lag screws into end-grain), and blocking inside the rim joist at every post location. If the existing framing does not have the blocking, we add it (priced as a per-post add-on on the quote). Newly installed railings get the right connection from day one.
One Handis crew start to finish — no sub coordination, no schedule gaps
Railings is pure carpentry. No licensed plumber, no licensed electrician, no permit through a third party in most jurisdictions (Seattle DCI does not require a building permit for a like-for-like railing replacement on an existing deck; new construction or a change in guard height or structural framing is a different matter). One Handis crew shows up, demos the old railing, installs the new system, hauls the debris, and runs the punch list with you at the end. Most railing projects finish in one to three working days depending on the run length.
Insured, background-checked, 30-day workmanship + 2-year structural warranty
Every Handis carpenter carries general liability and workers' compensation insurance and has cleared a background screening before the first job. The 30-day workmanship guarantee covers caulk joints, finish, and any cosmetic punch-list item. The 2-year structural warranty covers the post connections, the rail-to-post fasteners, and the infill anchoring — if a post loosens or a cable tensioner fails inside 2 years from our install, we come back and fix at no charge. Manufacturer warranties (cable, glass, aluminum, composite) run 10 to 25 years depending on the system and pass through to the homeowner at install.
Estimate
Tell us the railing run (linear feet, how many stair runs, any returns or corners), the deck height above grade (drives the 36 vs 42-inch height question), the material you are leaning toward (wood, cable, glass, aluminum, composite), and any constraints — view deck, dogs and kids, a hot tub on the deck, a fixed budget. We send back a clear estimate and a project timeline.
What Our Customers Say
Recent railing-install reviews from verified Seattle-area Handis customers across all five material systems.
Replaced a failing pressure-treated railing on the back deck of a 1996 split-level in Bothell with a clear cedar top rail and stainless cable infill. Handis pulled the old posts (the lags had pulled out of the rim joist on three of them), added blocking inside the rim at every new post location, set the steel posts through-bolted, and tensioned the cable on day two. Three working days. The torque-wrench photos showing every tensioner spec'd correctly were a nice touch.
Glass railing on a third-story balcony in West Seattle facing the Sound. Tempered laminated glass per code, frameless base-channel mount into the deck framing. Two working days for the install. They warned us about the squeegee maintenance schedule on the call — we have stuck to it monthly and the glass still looks like the day they finished. Worth the upgrade for the view.
Cedar railing replacement on the front porch of a 1923 craftsman in Wallingford. Wanted the traditional turned-baluster profile to match the original (the previous owner had put up a 2x2 picket replacement in the 90s that looked nothing like a craftsman porch). Handis sourced the turned cedar balusters, set the new posts, ran a shaped top rail and bottom rail to match historic profile. Two working days. House looks period-correct now.
Aluminum railing on a long back deck in Sammamish — about 65 linear feet with a stair run. We wanted zero maintenance going forward (the previous wood railing had been refinished four times in twelve years and was rotting at the bottom rail again). Powder-coated black, three working days. Two years in and it looks identical to install day. No staining, no sealing, no thinking about it.
Composite railing matched to our existing TimberTech decking on the back of a 2018 Issaquah build. The deck was the original Tigerwood Capped Composite and Handis sourced TimberTech Impression Rail in the matching tone with aluminum balusters. Two working days. The colors line up exactly like one project — the previous owner had put up a white vinyl railing that fought the deck color. Now the deck reads as one assembly.
