How to Screen In a Porch: Materials, Cost, and DIY Steps

Knowing how to screen in a porch transforms an underused outdoor space into a bug-free living area you will actually enjoy from spring through fall. A screened porch adds usable square footage, increases home value by an estimated 4-6%, and costs significantly less than a full room addition. Whether you hire a contractor or tackle it yourself, this guide covers everything from material selection to final installation.

Screened Porch Cost Overview

Budget varies widely depending on porch size, materials, and whether you are screening an existing covered porch or building new.

• DIY screening an existing covered porch: $500-$2,000 for a 200 sq ft porch (materials only)
• Professional screening of an existing porch: $2,000-$5,000 including labor and materials
• Building a new screened porch from scratch: $8,000-$25,000+ depending on size, roofing, and foundation

The DIY route saves 50-60% on labor, and screening is one of the more forgiving home projects for intermediate DIYers. The framing is simple, the screen installation is repetitive, and mistakes are easy to fix.

Choosing the Right Screen Material

Screen material selection affects durability, visibility, and cost. Here are the main options.

Fiberglass Screen

The most common and affordable option at $0.15-$0.30 per sq ft. Fiberglass is flexible, does not crease permanently, and is easy to install. Standard 18×16 mesh keeps out most insects while allowing good airflow. Downsides: it sags over time, tears more easily than metal, and UV exposure degrades it within 5-8 years.

Aluminum Screen

Stronger and more rigid than fiberglass at $0.25-$0.50 per sq ft. Aluminum resists sagging and lasts 10-15 years, but it dents and creases permanently, making installation less forgiving. Charcoal-colored aluminum provides better outward visibility than silver.

Pet-Resistant Screen (Phifer PetScreen)

Vinyl-coated polyester that is 7 times stronger than standard fiberglass. Resists claws and tears. At $0.50-$1.00 per sq ft, it costs significantly more but saves money long-term if dogs or cats regularly push against the screens.

Super Screen / High-Visibility

Uses thinner strands to maximize the view while maintaining insect protection. At $0.40-$0.80 per sq ft, this premium option is worth considering if your porch overlooks a view you do not want obscured.

Tools and Materials Needed

For a DIY screening project on an existing covered porch, gather these items before starting.

• Screen material (measure all openings and add 10% for waste)
• Pressure-treated 2×4 lumber for framing
• Screen molding or spline channel and rubber spline
• Spline roller tool ($5-$10)
• Screen door (pre-hung units from $100-$300)
• Staple gun and 3/8-inch stainless steel staples
• Miter saw or circular saw
• Drill/driver with exterior-grade screws
• Utility knife, tape measure, level

Step-by-Step Installation Process

Step 1: Plan the Layout

Measure each opening between existing porch posts. Determine where the screen door will go — typically centered on the side facing the yard. If openings are wider than 4 feet, plan to add intermediate vertical framing members (mullions) to support the screen. Unsupported spans over 4 feet sag and flex in wind.

Step 2: Build the Screen Frames

Cut 2x4s to fit each opening, creating a rectangular frame that sits flush with the outside face of the porch posts. Secure frames to the posts with 3-inch exterior screws, pre-drilling to prevent splitting. Use a level to keep everything plumb and square. For taller openings (over 7 feet), add a horizontal rail at 36-42 inches to divide the screen into upper and lower panels — this also provides a convenient ledge and makes future screen replacement easier.

Step 3: Install the Screen

Two methods work for attaching screen to wood frames.

Staple and trim method: Stretch the screen across the opening, staple it to the outer face of the frame at 2-inch intervals, pull tight, staple the opposite side, then trim the excess and cover the stapled edges with screen molding (1/4-round or lattice). This is the traditional approach and creates a clean finished look.

Spline channel method: Attach aluminum spline channel to the frame, press the screen into the channel using a spline roller and rubber spline cord, then trim the excess with a utility knife. This method holds tighter and makes future screen replacement simpler, but requires the spline channel hardware.

Step 4: Hang the Screen Door

Pre-hung screen doors ($100-$300) are sized for standard openings and include the frame, hinges, and hardware. Shim the frame plumb and level in the opening, then screw through the frame into the surrounding structure. Install a pneumatic or hydraulic door closer ($15-$25) to prevent slamming and ensure the door latches automatically — essential for keeping bugs out.

Step 5: Finish and Seal

Caulk any gaps between the screen frames and the existing porch structure. Paint or stain all exposed wood to match the porch. Add kick plates (aluminum panels at the bottom 12-18 inches) to protect screen from foot traffic and pet damage.

Common Mistakes to Avoid

Learning how to screen in a porch properly means avoiding these frequent errors.

• Not tensioning the screen enough — loose screen sags within weeks. Pull firmly and evenly before fastening
• Skipping the kick plate — bottom sections of screen take the most abuse. A $20 aluminum kick plate panel prevents tears
• Using interior-grade lumber — untreated pine rots within 2-3 years in an outdoor porch environment. Use pressure-treated lumber or cedar
• Forgetting a threshold seal — the gap under the screen door is an insect highway. Install a door sweep or threshold
• Ignoring water drainage — ensure the porch floor slopes slightly (1/8 inch per foot minimum) away from the house so rain blown through the screens drains out rather than pooling

Maintenance and Screen Replacement

Wash screens annually with a soft brush and mild soap to remove pollen, dirt, and cobwebs. Inspect frames for rot or damage each spring. Small holes or tears can be patched with screen repair patches ($3-$5 for a pack) — peel-and-stick patches work surprisingly well for temporary fixes.

When a full panel needs replacement, fiberglass screen is easier to re-stretch than aluminum. Budget 30-45 minutes per panel for replacement once you have the process down. Keeping a spare roll of screen material in storage saves a trip to the hardware store when damage occurs mid-season.
