Want to use your New Jersey backyard in more weather? You have three main ways to add an enclosed outdoor room: a screen room, a patio or porch enclosure, or a full sunroom (three- or four-season). They span a wide range of cost and comfort — from a simple bug-free porch to a fully insulated, year-round addition. This guide compares all three so you can pick the one that fits how you'll actually live and what you want to spend.

Prefer to stay open-air? A louvered or aluminum pergola gives shade and a defined outdoor space without enclosing it — and our pergola vs. sunroom guide compares open vs. enclosed.
1. Screen rooms & screened porches
A screen room is the simplest, most affordable way to extend your living space outdoors — fresh air and shade, minus the mosquitoes and ticks. We build new screened structures or convert an existing porch, deck, or patio, with the roof and framing done right for NJ weather. It's also a smart starting point: you can add glass later to upgrade to a three-season space.
2. Patio & porch enclosures (vinyl vs. glass)
An enclosure is the fastest way to make an existing patio or porch usable in more weather without building a full addition. The two main paths are vinyl window systems — budget-friendly, with panels you open in summer and close in cooler months — and glass enclosures, which cost more but give a brighter, more finished, sunroom-like feel. We assess the slab, roof, and structure, add a roof or footings if needed, and finish it to match your home.
3. Sunrooms: three-season vs. four-season
A sunroom is a true addition built onto your home. The big decision is insulation and climate control. A three-season room is bright and comfortable spring through fall at a lower cost; a four-season room is fully insulated, heated, and cooled for year-round use — and it adds heated square footage and resale value. We build custom sunrooms as real additions rather than installing prefab kits, so the insulation and roofline match your house.
A three-season room is right if you…
- Mainly want the space spring through fall
- Want a bright room at a lower cost
- Are okay closing it down in deep winter
A four-season room is right if you…
- Want to use the room every month of the year
- Want insulated, heated, and cooled comfort
- Want to add heated square footage and resale value
What they cost in New Jersey
Cost rises with how enclosed and how climate-controlled the room is: a screen room is the most affordable, enclosures sit in the middle, and a four-season sunroom is the biggest investment because of insulation, HVAC, and a full foundation. For NJ-specific ranges, run the numbers in our sunroom cost calculator, or read our cost guides for screened rooms, 3-season sunrooms, and 4-season sunrooms.
Permits, foundations & NJ weather
Most of these projects need a permit, and rules vary township by township. A sunroom is always a structural addition that needs a permit and a true foundation — see do sunrooms need foundations? Screen rooms and enclosures usually need permits too. Whatever you build, we engineer the roof, footings, and glazing for Jersey snow load and — near the shore — wind and salt air, and we handle the paperwork across Monmouth, Ocean, Middlesex, Somerset, and Union counties.
Common questions
What's the difference between a screen room, an enclosure, and a sunroom?
A screen room uses screening for airflow and bug protection (an outdoor room). An enclosure closes in an existing patio or porch with vinyl or glass for three-season use. A sunroom is a fully built addition — three-season, or insulated four-season for year-round, heated living space.
Can you convert my existing porch, deck, or patio?
Usually, yes — that's a big part of what we do. We assess the existing structure and roof, reinforce it if needed, and screen or enclose it properly. If a new roof or footings are required, we handle that as part of the build.
Which option adds the most home value?
A four-season sunroom generally adds the most measurable value because it adds insulated, heated square footage that appraisers and buyers can count. Screen rooms and enclosures add strong usability and appeal but don't add heated interior square footage.
Vinyl or glass for an enclosure?
Vinyl window systems are budget-friendly and great for three-season use with openable panels. Glass enclosures cost more but give a brighter, more finished, sunroom-like look. We'll walk you through both on site.
What does each option cost in NJ?
It depends on size, how enclosed the room is, and finishes. Use our sunroom cost calculator for a ballpark across all three, then we'll give you an exact quote on site.
