TWD Carpentry is a licensed and insured deck restoration company based in Bonner, MT, serving homeowners throughout Missoula County. Owner Tom Dorrell — a journeyman carpenter with 35+ years of experience — personally inspects, repairs, and refinishes every deck. No subcontractors. No crew rotations. One experienced carpenter from first board to final coat.
Montana decks take a beating. Between 5+ months of freeze-thaw cycling, intense summer UV, and heavy snowpack that sits for weeks, wood deteriorates faster here than almost anywhere in the lower 48. Tom understands these conditions because he has been working on Missoula County homes since the 1980s. He knows which stain products hold up through a Bonner winter, which wood species resist the Blackfoot Valley's moisture levels, and when a deck has crossed the line from "needs refinishing" to "needs structural work."
Deck Restoration Services in Missoula County
Pressure Washing & Eco-Friendly Cleaning
Professional deck washing removes mold, mildew, algae, and years of embedded grime. Tom uses eco-friendly cleaners safe for Missoula County waterways and adjacent landscaping.
Sanding & Stripping
Old finishes are sanded or chemically stripped to bare wood. This step is critical — new stain will not penetrate properly over remnant coatings, which is the leading cause of early peel in Montana decks.
Staining & Sealing
Penetrating stains with UV inhibitors protect against Missoula's high-altitude sun exposure. Tom applies sealant rated for below-zero temperatures and heavy moisture — the two conditions that destroy unprotected decks fastest.
Board Replacement
Rotted, split, or warped boards are replaced individually — no need to tear out an entire deck when only a section has failed. Tom matches wood species, grain pattern, and board width for a seamless result.
Trex Composite Decking
Trex composite runs $8–$14 per square foot for materials and eliminates annual staining. It resists rot, insects, and UV fading — a strong choice for Montana homeowners tired of yearly maintenance.
Railing Repair & Replacement
Wobbly posts, loose balusters, and cracked railings are safety hazards. Tom repairs or replaces railing systems to meet code and restore structural integrity — wood, composite, or metal.
How Much Does Deck Restoration Cost in Missoula, MT?
Basic deck cleaning and staining runs $2–$5 per square foot in Missoula County. Board replacement adds $8–$15 per square foot depending on wood species and accessibility. A full Trex composite conversion for a 300-square-foot deck typically costs $4,000–$7,000 installed. Tom provides free on-site estimates with exact pricing — no ballpark guesses, no hidden fees.
What Every Montana Deck Owner Should Know
Stain vs. Paint: Which Lasts Longer?
Stain penetrates wood fibers and moves with natural expansion and contraction. Paint forms a surface film that cracks during Montana's freeze-thaw cycles. Tom recommends semi-transparent penetrating stain for most Missoula County decks — it lasts 2–4 years between applications and ages gracefully instead of peeling.
Trex Composite vs. Natural Wood
Trex costs roughly 2–3x more upfront than pressure-treated lumber but requires zero staining and resists rot, warping, and insect damage. For homeowners who want a low-maintenance deck that handles Bonner's heavy snowpack and Potomac's spring runoff, composite pays for itself within 5–7 years in saved maintenance costs.
How Montana Weather Destroys Decks
Water seeps into unprotected wood grain, freezes overnight, and expands. Repeat that 100+ times per winter and boards split from the inside out. Summer UV then bleaches and dries the exposed fibers. This cycle is why unfinished decks in Missoula County lose structural integrity within 3–5 years.
How Often Should You Reseal?
Every 2–3 years for most wood decks in western Montana. South-facing decks with full sun exposure may need resealing every 18–24 months. Tom inspects deck condition during every estimate and recommends a maintenance schedule based on your specific wood type, orientation, and altitude.
How Tom Restores Your Deck — Step by Step
Inspection & Cleaning
Tom inspects the full deck structure — joists, ledger board, posts, railings, and surface boards. He identifies rot, insect damage, loose fasteners, and structural concerns. Then the entire deck is pressure-washed or eco-cleaned to remove mold, mildew, and embedded dirt.
Sanding & Stripping
All deck surfaces are sanded to remove old finish and smooth the grain. Chemical strippers are used on stubborn coatings. This step ensures the new stain bonds directly to fresh wood — the single most important factor in how long your finish lasts.
Repair or Replacement of Damaged Boards
Rotted, cracked, or warped boards are pulled and replaced with matched lumber. Loose railings are secured. Compromised joists are reinforced or swapped. All structural work is completed before any finish is applied.
Staining, Sealing & Final Inspection
A penetrating stain with UV protection is applied in even coats, followed by a clear sealant rated for Montana's freeze-thaw conditions. Tom performs a final walkthrough to verify even coverage, secure fasteners, and a clean finish edge-to-edge.
Deck Restoration Questions
A standard cleaning, sanding, and staining project takes 2–3 days. If board replacement or structural repair is involved, expect 4–7 days depending on deck size and the extent of damage. Tom provides a timeline estimate during every free on-site assessment.
Stain is the better choice for Montana decks. It penetrates the wood grain and flexes with seasonal expansion and contraction caused by freeze-thaw cycles. Paint sits on the surface and typically cracks and peels within 2–3 years in Missoula County's climate. Tom recommends semi-transparent penetrating stain for the best balance of protection and natural wood appearance.
Trex composite costs $8–$14 per square foot for materials — roughly 2–3x more than pressure-treated lumber. But it eliminates annual staining, resists rot and insect damage, and handles Montana's snow load and UV exposure without degrading. Most homeowners recoup the extra cost in 5–7 years of saved maintenance. Tom installs both wood and composite and can help you weigh the options for your specific deck.
Every 2–3 years for most wood decks in the Missoula area. South-facing decks with heavy sun exposure may need resealing every 18–24 months. Montana's combination of intense UV and repeated freeze-thaw cycles breaks down sealant faster than milder climates. Tom assesses condition during every visit and recommends a maintenance plan based on your deck's wood type and orientation.
One Carpenter. Start to Finish.
Most deck contractors send a pressure-washing crew on Monday and a different staining crew on Thursday. Tom Dorrell does every phase himself — inspection, cleaning, sanding, repair, staining, and final walkthrough. That means consistent results, no communication breakdowns between trades, and one person accountable for the entire project.
Tom has restored decks across Bonner, East Missoula, Potomac, Lolo, and throughout the Blackfoot Valley. He knows which lumber yards carry the best pressure-treated stock, which stain brands survive a Montana winter, and how to reinforce ledger boards on homes built in the 1970s and '80s. That is the kind of local knowledge that only comes from 35 years working in the same county.
