Planning guide · 01

Screen room, three-season, or all-season—which one fits?

The right answer starts with how many months you want to use the room, how closely it should feel connected to your home, and what level of comfort you expect.

Screen room

Choose a screen room when fresh air and protection from insects are the priority. It gives you shade and a comfortable outdoor room while staying intentionally open to the weather.

Three-season room

A three-season room uses windows and doors to extend spring and fall use. It offers more protection and flexibility than screening, without becoming fully conditioned year-round living space.

All-season room

An all-season room is built as true living space, with an insulated structure, high-performance glass, and heating and cooling planned for winter and summer comfort.

What to look for before hiring a sunroom builder

A beautiful rendering is only the beginning. The best proposal explains how the new room connects to your house, keeps water out, and performs over time.

Ask for drawings

You should be able to see the roofline, openings, room dimensions, and connection points before construction begins.

Read the material details

Look beyond broad promises. Insulation, window glass, flashing, water barriers, interior finishes, and exclusions should be described clearly.

Understand the contract

Know the scope, payment milestones, permit responsibility, and change-order process. Mattison does not take a deposit until you have a detailed contract and approved drawings.

How an existing porch becomes a room you can really use

A porch conversion can be one of the smartest ways to gain space, but only after the existing foundation, roof, and connection to the house have been evaluated.

Inspect first

We begin by checking structure, drainage, roof conditions, floor height, and how the porch meets the house. Those conditions determine what can be reused.

Design for the goal

A screen room, three-season room, and all-season room place different demands on the existing structure. The window layout, insulation, and mechanical plan follow the intended use.

Finish it like part of the home

The final details—trim, transitions, siding, doors, and sightlines—are what make a conversion feel intentional rather than added on.
