Why Wrap Your Door Frame With Aluminum?#

Before diving into the installation process, it’s helpful to understand the key benefits of aluminum cladding for door frames:

• Weather resistance: Blocks rain, humidity, and UV rays to prevent wood rot, warping, or fading
• Ultra-low maintenance: No annual repainting required; simply wipe clean with soap and water
• Curb appeal: Pre-painted aluminum coil stock is available in dozens of colors to match your home’s exterior trim
• Energy efficiency: Adds a thin insulating layer to reduce drafts and lower heating/cooling costs
• Cost savings: Avoids expensive full frame replacements, which can cost $500+ per entry door

10 Easy Methods to Wrap a Door Frame With Aluminum#

Each method follows a sequential, beginner-friendly workflow to ensure a perfect fit:

Method 1: Measure the Door Frame Precisely#

Inaccurate measurements are the top cause of gaps and uneven wraps.

1. Measure the full height of each side jamb, the full width of the head (top) jamb, and the depth of the frame reveal (the edge that sits against the door stop)
2. Add 1 inch to all measurements to account for overlapping edges and trim allowances
3. Double-check all measurements before cutting; for uneven frames, measure the widest and tallest points to ensure full coverage

Method 2: Cut Aluminum Coil Stock to Size#

1. Lay the aluminum coil flat on a stable work surface, and mark your measurements with a permanent marker
2. Use tin snips for long straight cuts, or score the aluminum with a utility knife and bend back and forth to snap cleanly for shorter cuts
3. Cut the head jamb piece first, followed by the two side jamb pieces
4. Wear work gloves at all times to avoid cuts from sharp aluminum edges

Method 3: Prep the Existing Door Frame Surface#

Proper surface prep ensures adhesive sticks and prevents hidden damage under the wrap:

1. Scrape off all old caulk, peeling paint, and dirt from the frame
2. Sand rough spots with 80-grit sandpaper, then smooth the entire surface with 220-grit sandpaper
3. Fill small cracks or holes with wood filler, sand smooth once cured
4. Cut out and replace any severely rotted wood sections before wrapping
5. Wipe the entire frame with a damp cloth to remove dust, and let it dry completely

Method 4: Bend Aluminum Edges for a Snug Fit#

Bending lips into the aluminum creates a flush, waterproof seal:

1. Use a sheet metal brake or clamped straight edge to bend a ½-inch lip along the edge of each aluminum piece that will sit against the wall
2. Bend a second ½-inch lip along the edge that will sit against the door stop
3. Test the bend angle against your frame to adjust for a tight fit before moving to installation

Method 5: Dry-Fit the Aluminum Wraps Before Adhesion#

Never apply adhesive before testing the fit of your pieces:

1. Hold each cut and bent piece up to the frame to check alignment
2. The head jamb piece should extend ½ inch past each side jamb to create a waterproof overlap
3. Side jamb pieces should extend ½ inch past the bottom of the frame to cover the sill edge
4. Trim excess aluminum or adjust bends as needed, then mark the position of each piece on the frame with painter's tape for easy alignment later

Method 6: Apply Adhesive & Sealant to the Frame#

1. Run a continuous ¼-inch bead of construction adhesive along the entire surface of the wood frame
2. Add a thin bead of butyl sealant along the edges of the frame where the aluminum lips will sit to create a secondary waterproof barrier
3. Avoid applying too much adhesive, as it will squeeze out when you press the aluminum on and create a messy finish

Method 7: Secure the Head Jamb Wrap First#

Always install the top piece first to ensure proper water runoff for exterior frames:

1. Align the head jamb aluminum piece with the marks you made during dry fit
2. Press it firmly against the adhesive, starting from the center and working out to the edges to remove air bubbles
3. Use a rubber mallet to gently tap the edges to ensure the lips are seated snugly against the wall and door stop
4. Wipe away any excess adhesive that squeezes out with a damp cloth immediately

Method 8: Install Side Jamb Wraps Next#

1. Slide the top edge of each side jamb piece under the overlapping edge of the head jamb piece to prevent water from seeping between the seams
2. Press each side piece firmly against the adhesive, working from top to bottom to remove air bubbles
3. Tap the edges with a rubber mallet to seat the lips fully
4. For extra hold on high-traffic exterior doors, add 2-3 countersunk stainless steel self-tapping screws along the inner edge of each side jamb, spaced evenly apart

Method 9: Seal All Seams & Edges#

Sealing is critical to prevent water damage and extend the life of your wrap:

1. Run a thin, continuous bead of butyl rubber sealant along all seams: where the head jamb meets the side jambs, where the aluminum meets the wall, and where the aluminum meets the door sill
2. Smooth the sealant with a caulk smoothing tool or gloved finger to create a flush, even finish
3. Wipe away any excess sealant with a damp cloth before it dries
4. Add a small dot of sealant over each screw head to prevent corrosion

Method 10: Clean Up & Inspect Your Work#

1. Remove any painter's tape while the sealant is still wet to avoid pulling dried sealant away from the seams
2. Wipe the entire aluminum frame with glass cleaner or metal polish to remove marker marks, adhesive residue, or fingerprints
3. Inspect the entire wrap for gaps, air bubbles, or loose edges:
   • Fill small gaps with extra sealant
   • Poke air bubbles with a pin, press the air out, and seal the hole with a tiny dot of sealant
   • Press down any loose edges and add a small amount of adhesive under the edge to secure it

Pro Tips for a Long-Lasting Aluminum Wrap#

1. Opt for pre-painted aluminum coil stock that matches your home's trim to avoid painting after installation
2. If you don't own a sheet metal brake, most home improvement stores will cut and bend aluminum to your measurements for a small fee ($10-$20 per frame)
3. Add a thin foam insulation strip behind the aluminum wrap for extra energy efficiency, especially for exterior entry doors
4. For coastal homes, choose marine-grade aluminum coil stock to resist salt corrosion
5. Avoid using steel screws, as they will react with aluminum and cause rust over time

---

Common Mistakes to Avoid#

1. Skipping surface prep: Dirt, old paint, or rot under the wrap will cause adhesive to fail and wood to deteriorate hidden from view
2. Butting seams instead of overlapping: Non-overlapped seams will leak water and cause damage over time
3. Using the wrong sealant: Silicone sealant does not adhere well to aluminum, and acrylic sealant will crack in extreme temperatures. Stick to butyl rubber sealant for best results
4. Leaving sharp edges: File down any sharp cut edges to avoid accidental cuts during installation or later use
5. Forgetting to ventilate: For interior door frames, leave a 1/8-inch gap at the bottom of side jambs to allow air circulation and prevent trapped moisture

FAQs About Aluminum Door Frame Wraps#

Q: How much does it cost to wrap a door frame with aluminum?#

A: For a standard 36-inch entry door, materials cost between $50 and$150, depending on the quality of aluminum and sealant you choose. Hiring a professional costs between $300 and$600 for the same job.

Q: How long does aluminum door frame wrapping last?#

A: With proper installation, aluminum wraps last 20 to 30 years before needing replacement.

Q: Can I wrap a metal door frame with aluminum?#

A: Yes! Just use a metal-compatible construction adhesive instead of wood adhesive, and sand the metal frame lightly to create a rough surface for the adhesive to stick to.

Q: Can I paint aluminum wrap after installation?#

A: Yes, as long as you use a paint formulated for metal surfaces and prime the aluminum first. Pre-painted coil stock is recommended for longer-lasting, fade-resistant color.
