Wood Deck Railing Cost
Traditional 2×2 baluster + 2×4 rail wood construction, PT pine or cedar. Lowest material cost, highest labor cost, requires biennial sealing to last past year 8.
Estimate your wood railing cost
The calculator below is seeded with a 16×20 deck. It builds your full deck budget — switch the railing line to wood at roughly $28–$55/lf and enter how many feet of perimeter actually get a rail (skip the house side and any stair openings).

Building permit included in budget
IRC R105Northeast typical permit fee is in the budget. Most jurisdictions require a permit for decks > 200 sqft, > 30″ above grade, or attached to the house.
Hidden-fastener install premium baked in
Manufacturer specsMid composite uses hidden-fastener clip systems (Cortex / CamoClip / Trex Universal) — labor takes 25–30% longer than face-screwing PT. Already inside the tier's installed $/sqft band.

What wood railing costs
Wood deck railing is priced per linear foot, not per square foot — railing follows the deck's edge, so the deck's footprint barely matters compared with its perimeter. Installed, expect $28–$55/lf including posts, top and bottom rails, infill, and labor. The low end assumes a straightforward ground-level run with simple corners; the high end reflects elevated decks, more posts, stair returns, and premium finishes.
Worked example. A 16×20 deck has a 72-foot perimeter. Railing the entire edge would cost about $2,016–$3,960 in wood. Most decks attach to a house on one 16-foot side and have a stair opening, so the truly railed length is closer to 56–60 feet — trimming the realistic budget to roughly $1,568–$3,300.
Code compliance (IRC R312)
Build-to-code requires precise 4″ sphere spacing (R312.1.3). DIY builds typically fail inspection on inconsistent baluster spacing — use a spacing template not eyeball.
IRC R312 governs guard height (36″ residential when the walking surface is more than 30″ above grade) and the 4″ sphere rule for infill spacing. Whatever system you choose, the inspector checks those two things first — buy a pre-engineered, code-rated assembly where you can and keep the manufacturer's spec sheet for the permit file.
Maintenance & warranty
Re-seal every 2-3 years (~$0.85/lf per cycle). Replace splintering balusters every 8-12 years. Top rail typically warps + needs replacement at year 10-15.
Typical warranty for wood systems: PT lumber 25 yr (rot only), no system warranty. Read the small print — most warranties cover the finish or the material against defects, not labor to remove and reinstall, and many are voided if you mix components across brands. Over a 25-year horizon the maintenance cadence above matters as much as the sticker price; a cheaper system that needs frequent re-sealing or re-tensioning can cost more in total than a higher-priced, maintenance-free one.
Wood railing cost by deck size
Installed wood railing at $28–$55/lf, applied to the full perimeter of each common deck size. This is an upper bound: real railing length is usually less, because the house side and stair openings don't get a rail. Subtract those runs for your actual number.

Perimeter = 2 × (length + width). Costs use the wood installed range and assume every edge is railed — deduct the attached house side and any stair openings to get your real linear footage, then re-price in the calculator above.
FAQ — Wood deck railing cost
How much does wood deck railing cost?
Wood deck railing runs about $28–$55 per linear foot installed (materials + labor). On a 16×20 deck — roughly 72 linear feet of perimeter — that works out to about $2,016–$3,960 if the entire perimeter is railed. In practice you exclude the house side and any stair openings, so the real number is usually lower. Use the calculator above to enter your exact railed length.
Is wood railing code-compliant?
Build-to-code requires precise 4″ sphere spacing (R312.1.3). DIY builds typically fail inspection on inconsistent baluster spacing — use a spacing template not eyeball.
How much maintenance does wood railing need?
Re-seal every 2-3 years (~$0.85/lf per cycle). Replace splintering balusters every 8-12 years. Top rail typically warps + needs replacement at year 10-15. Typical warranty: PT lumber 25 yr (rot only), no system warranty.
Is wood railing worth it?
Budget DIY builds, traditional architecture, period homes, owners willing to commit to biennial maintenance. Easiest to color-match to existing decor. Watch-outs: True 25-year TCO often EXCEEDS composite once maintenance is factored. Splintering balusters are a safety issue and a deal-killer at resale. Cedar costs ~50% more than PT for marginal lifespan gain.
