Exterior & Entry Door Installation in Tacoma, WA · Fully Insured

Exterior & Entry Door Installation in Tacoma means setting a weather-tight seal against the wind-driven rain that rolls off Puget Sound across the North End, Stadium District, and South Hill neighborhoods. Tacoma's Victorian and Craftsman homes, built a century ago from old-growth Douglas fir, sit on hills exposed to Pacific storms that drive moisture into door frames, thresholds, and sills. Entry doors at the front, back, and French doors along decks face constant moisture and the slow rot that follows. We repair sound door frames and thresholds where the wood justifies it, and replace the full unit with proper sill pan and head flashing where rot has compromised the structure. The goal is a door that functions, seals tight, and lasts without leaking into the rim joist or subfloor behind it.

Why Door Rot Matters in Tacoma Homes: Moisture, Time, and the Cost of Waiting

Tacoma gets about 40 inches of rain a year over long gray winters, and the entry door is the first point of failure. Wind-driven rain finds its way past weatherstripping and into the door jamb, sill, and the framing behind it. Rot starts at the threshold, spreads into the sill plate, and over years moves into the floor joist and subfloor. A rotted entry door frame is not just an aesthetic problem, it is a pathway for water and pest damage deeper into the home.

• Rotted thresholds and sills allow water to wick into the rim joist and floor structure below the door opening.
• Compromised door frames lose their seal and let wind-driven rain penetrate the door jamb and interior walls.
• Doors that no longer close or latch properly signal frame movement or rot that has weakened the opening.
• Delayed repair of a rotted entry door often means replacing the joist or subfloor later, at much higher cost.
• A new door installed without proper sill pan and flashing will rot again within a few years in Tacoma's climate.

Address a rotted entry or back door early, before the damage spreads into the structure. We inspect the frame, sill, and surrounding wood, and propose repair or replacement based on what the wood can support.

Key info: In Tacoma and Gig Harbor, we often see rot starting at the threshold where water pools against the door sill. A rotted threshold can be replaced without replacing the entire door frame if the jambs and header are still sound. We check this carefully and only replace the full unit if the rot has spread.

How We Install or Repair Entry Doors: The Process from Opening to Seal

Entry door installation begins with a careful inspection of the existing frame, sill, and the wood around the opening. If the frame is sound but the threshold is rotted, we replace just the threshold and reseal the door. If the frame, sill, or jambs show rot, we remove the door and frame, inspect the rim joist and subfloor, and install a new unit with a proper sill pan and head flashing to keep water out for years to come.

• We inspect the existing door frame, sill, threshold, and the wood structure around the opening for rot or damage.
• If repair is possible, we replace rotted components (threshold, sill trim, or casing) and reseal the door with new weatherstripping.
• If the frame or sill is too far gone, we remove the door and frame, check the rim joist and subfloor for rot, and install a new door with a sill pan and head flashing.
• We set the new door plumb, level, and square, shim the jambs, and seal the gap between the frame and the rough opening with foam and caulk.
• We install interior casing and exterior trim or brick molding to finish the opening and tie it to the siding or brick.

The entire process, from removal to installation and trim, typically takes one to two days depending on the condition of the opening and whether the subfloor needs repair.

Example: A 1910 Craftsman bungalow in the North End of Tacoma had a rotted entry door sill and threshold. The frame and jambs were sound, so we replaced the threshold, re-caulked the sill, and installed new weatherstripping. Cost was under $1,200, and the door now seals tight. Had we waited another two years, the rot would have spread into the rim joist and cost $3,500 or more to repair.

Repair vs. Replace: When to Fix a Door and When to Install New

We propose repair when the wood is sound and the damage is localized. We recommend replacement when rot has compromised the frame, sill, or structure, or when a door is old and the cost of repeated repairs exceeds the cost of a new unit.

Exterior & Entry Door Installation Cost in Tacoma: What to Expect

Entry door repair and installation in Tacoma runs from around $850 for threshold and weatherstripping repair on a sound frame, to $2,500 to $4,500 for a full door and frame replacement with new sill pan, head flashing, and finish trim. The cost depends on the extent of rot, whether the rim joist or subfloor needs repair, the type and quality of the new door, and the finish trim required to tie the opening to your siding or brick.

Factors that affect the cost:

• Threshold or sill repair only costs less than a full frame replacement because the opening remains intact.
• A full door and frame replacement is more expensive if the rim joist or subfloor is rotted and needs sistering or replacement.
• The quality and style of the new door (solid wood, fiberglass, steel, or composite) affects the material cost and installation time.
• Exterior finish trim, brick molding, or casing to match existing siding adds to the total, especially on historic homes where materials must match.
• Access and site conditions, such as a tight entryway or a porch that must be temporarily removed, can add time and cost.

What to Look for When Hiring a Carpentry Contractor Near Me in Tacoma

Choosing the right carpenter for your entry door repair or installation matters because a poorly installed door will leak, and a poorly sealed opening will fail again within a few years. Look for a contractor who inspects the frame carefully, explains the repair or replacement recommendation clearly, and installs doors with proper flashing and sealant. Get at least two or three estimates so you understand the range and scope of the work.

• Verify that the contractor is fully insured and can provide a certificate of insurance before work begins.
• Ask for references from recent projects in Tacoma, Gig Harbor, or Lakewood so you can speak to homeowners about their experience.
• Confirm that the contractor will install a sill pan and head flashing on any new door to prevent water intrusion in Tacoma's wet climate.
• Understand whether the estimate includes finish trim, interior casing, and exterior brick molding or if these are priced separately.
• Ask about the timeline and whether the contractor can start within your preferred window, especially if the door is already leaking.

A good contractor will take time to explain what is wrong, why, and what it will cost to fix. They will not pressure you into replacement when repair is the honest answer.
