Over time, exterior door frames exposed to the elements can fall victim to wood rot, compromising their structural integrity. But how much does it actually cost to repair or replace a rotted door frame?

This guide examines the factors that influence exterior door frame rot remediation costs, when DIY repairs are practical, and how to budget for full frame replacement by a contractor. Read on for a detailed overview of what to expect when tackling this common exterior maintenance issue.

How Much Does Rotted Exterior Door Frame Cost?

The total cost to replace a rotted exterior door frame spans from $550 to $1,650+. Replacing the entire frame is an investment, but provides long-term rot resistance and performance.

If the rot is widespread and deeply embedded, DIY fixes won’t suffice – full professional replacement is likely required. Typical contractor costs for a complete rotted door frame replacement:

• Removal & Disposal – $150-300 to fully demo old frame and prep the rough opening
• New Frame Materials – $100-500 depending on size and material
• Installation Labor – $200-600 based on complexity and accessibility
• Weatherproofing – $100-250 to properly seal and protect the new frame

Other Potential Costs to Factor In

• Structural Repairs – Rot may compromise walls, requiring $500+ in repairs.
• New Hardware – Hinges, locks, etc. add $50-150.
• Painting/Staining – Aesthetically finish the new frame for $100-300.
• Permits – Some areas require permits for exterior door work ($50-100).

According to HomeGuide, if the door frame is beyond repair, replacing an exterior door frame typically costs between $131 and $382. For minor repairs, costs can range from $75 to $90, while larger repairs may cost between $110 and $220.

Another source, Angi, states that the overall cost to replace an exterior door frame generally falls between $130 and $400. The average cost for a complete replacement, including labor, is around $400, with material costs ranging from $80 to $500 depending on the type of door and frame.

According to an article on Alpine Door Service, repairing a rotted door frame can cost between $100 and $300, depending on the severity of the rot. If the entire frame needs to be replaced, costs can escalate significantly, with estimates ranging from $200 to $650.

What Causes Exterior Door Frames to Rot?

Wood door frames installed outside are under constant assault from rain, humidity, sprinklers, and snow. This persistent moisture exposure eventually penetrates the wood grain, causing rotting and decay. Areas where water pools, like the bottom of the frame, are particularly vulnerable.

Once rot takes hold, it quickly spreads through untreated wood. Catching it early is essential to limiting repairs.

Exterior Frames Rot Faster

Exterior door frames face much harsher conditions than interior ones:

• Direct rain and humidity exposure
• Seasonal freezing and thawing cycles
• Intense UV radiation from sunlight
• Greater temperature extremes and shifts

This punishing combination of moisture, sun, and dramatic thermal changes degrades exterior wood much faster. Interior doors may last 50+ years protected indoors, while exterior units often need replacement after 10-15 years.

Neglecting Rot

Ignoring initial signs of rot like isolated dark spots or soft areas allows it to expand dramatically. As rot eats deeper into the wood, it compromises the structural integrity of the entire frame. This can lead to:

• Sagging or detached frame sections
• Broken hardware as wood weakens around screws
• Leaks and drafts as insulation degrades
• Eventual need to replace the entire frame and door

Catching rot early and arresting it with DIY fixes can save thousands in replacement costs down the road.

Signs Your Door Frame is Rotting

Some common signs of a rotted door frame include:

• Visible wood damage – Peeling paint, soft spots, dark stains, mold growth
• Sagging or detached frame – Loss of structural integrity as rot spreads
• Insulation leakage – Gaps around frame let air penetrate
• Swollen door – Moisture causes expansion and sticking

Inspect regularly, especially after heavy rains, for early signs of trouble. Addressing minor rot now prevents major headaches later.

Factors Affecting Rotted Door Frame Repair Cost

Several important variables affect the cost and scope to repair or replace a rotted exterior door frame:

• Extent of Damage – Widespread decay escalates repair difficulty and material needs.
• Door Size – Larger doors require bigger, more expensive frames.
• Frame Material – Wood is cheapest but rots most easily. PVC and composites resist rot longer.
• Location Access – Harder to reach frames drive up labor hours.
• Customization – Ornate or non-standard frames cost more.
• Labor Rates – Prevailing costs for carpenters vary considerably by region.

Carefully considering these factors allows setting realistic rot remediation budgets.

Cost to Repair Minor Rot Damage

If the rot damage is relatively minor and localized, do-it-yourself repairs are very achievable. Typical DIY repair costs:

• Sanding/Scraping – $20 for sandpaper, blades to remove degraded wood
• Filling Small Holes – $50-75 per tube of epoxy or wood filler
• Applying Consolidants – $75-100 to strengthen partially decayed wood
• Protective Sealants – $50-75 for waterproofing coatings

With the right materials and some diligent elbow grease, minor rot damage can often be arrested for $200 or less in DIY supplies. This small investment saves thousands over full frame replacement.

When DIY Rot Repairs Are Practical?

DIY repairs for surface-level rot may suffice if:

• Damage is limited to small, localized areas
• Only surface wood layers are impacted
• The overall frame structure remains sound

In these cases, applying wood consolidants, fillers, and sealants can add years of life before full replacement is needed.

When Can I DIY the Repair?

This table provides guidance on whether DIY or contractor repair is best based on the observed extent of rot damage:

Damage Level	Repair Approach	Typical Cost Range
Surface decay in isolated spots	DIY fixes	$50 – $200
Less than 25% frame degradation	Potential DIY	$200 – $800
25-50% of frame affected	Call contractor	$800 – $1,200
Over 50% of frame rotted	Full replacement	$1,200 – $1,800

DIY Tips vs. Hiring a Carpenter

When DIY repairs may suffice:

• Addressing minor rot limited to surface wood layers
• Using consolidants and fillers for small, stable areas of decay
• Basic preventative sealing and weatherproofing

When to hire a professional:

• Extensive rot through over 50% of the frame
• Structural instability or wall/siding damage
• Moisture issues beyond just the frame
• Full frame demolition and replacement
• Precise experience fitting and sealing new frames

Seeking contractor help for major rot remediation ensures the job gets done properly. But diligent DIYers can handle smaller fixes.

Step-by-Step Replacing

If replacement is needed, the process usually involves:

1. Remove hardware (lockset, hinges) from old frame.
2. Carefully detach old frame from the rough opening using pry bar and hammer.
3. Remove remaining rotted wood with chisel and prep opening for new frame.
4. Cut, fit, and secure new frame using shims, nails, and screws. Seal joints with caulk.
5. Weatherproof frame with protective barriers and sealants.
6. Reinstall door hardware on completed frame.
7. Make final adjustments so door operates smoothly.

Preventing Future Door Frame Rot

To avoid repeated rot issues, take preventative measures:

• Inspect regularly for early signs of decay
• Keep exposed wood painted/stained
• Caulk joints between frame and siding
• Ensure door closes tightly against weatherstripping
• Install flashing above frame to divert water
• Repair gutters and drainage issues
• Consider rot-resistant frame materials

Proper maintenance saves money over the long haul.

Final Words

Catching exterior door frame rot issues early is critical to keeping repair costs manageable. While full frame replacement runs $550 to $1,650+, diligent DIY maintenance can arrest surface-level decay for under $200 in many cases.

Regardless of which repair approach makes sense, addressing rot issues promptly reduces expenses and home exterior damage down the road. Investing in preventative maintenance also pays dividends through avoided repairs. Keep your eyes peeled for early signs of trouble, and take action before rot gets out of hand.
