Why Build a Screened-In Porch?
Framing and screening a porch adds:

- Extended living space for relaxation or entertaining.
- Increased property value through added functionality and curb appeal.
- Energy savings by providing a shaded, breezy outdoor retreat.
Materials Needed for Framing a Screened-In Porch
When framing a porch, using the right construction materials ensures stability and longevity. Common materials include:
- Pressure-treated lumber – for structural framing and support posts.
- 2×4 or 2×6 boards – for the top and bottom plates of the screen wall.
- Decking boards – for flooring (if not already in place).
- Screening material – fiberglass, aluminum, or specialty screens.
- Fasteners – screws, nails, brackets, and joist hangers.
- Trim pieces – to cover edges and secure screens.
Steps to Frame a Screened-In Porch
1. Plan and Measure
- Assess the existing porch or deck area.
- Measure dimensions to determine how many studs and screens are required.
- Check for proper permits and building codes in your area.
2. Install Support Posts
- Use pressure-treated 4×4 or 6×6 posts for vertical support.
- Secure posts into the deck or concrete base using anchors.
3. Add Top and Bottom Plates
- Attach bottom plates (2×4 or 2×6 boards) along the deck floor.
- Install top plates parallel to the bottom plates, connecting them with studs.
4. Frame Wall Sections
- Build wall sections with vertical studs spaced 16–24 inches apart.
- Include openings for screen doors if needed.
- Secure the wall frames to the support posts.
5. Install Screens
- Roll out the chosen screen material.
- Staple screens tightly over the framed sections.
- Cover staples with trim pieces for a clean finish.
6. Add Roof Framing (if required)
- If the porch doesn’t already have a roof, construct rafters and beams.
- Ensure proper slope for drainage and weather protection.
Cost of Framing a Screened-In Porch
The cost depends on size, materials, and labor.
| Porch Size | DIY Cost (Materials Only) | Professional Installation |
|---|---|---|
| Small (8×10 ft) | $1,000 – $3,000 | $4,000 – $7,000 |
| Medium (12×14 ft) | $2,500 – $6,000 | $8,000 – $12,000 |

DIY framing is more affordable, but hiring professionals ensures compliance with building codes and a polished finish.
