FAQ
Frequently asked questions
What is a three season room?
A three season room is an enclosed room with windows or screens that you can use from spring through fall. It is usually not heated or insulated for winter, which sets it apart from a four season addition.
Can PLJ turn my existing deck into a three season room?
Often, yes. If the deck framing and footings can carry the added load of walls and a roof, we can enclose it. If not, we reinforce or rebuild the base first. PLJ checks this during the estimate visit.
Do I need a permit for a three season room?
Yes. A three season room adds walls and a roof to the house, so it needs a building permit. Lots near wetlands or homes in a historic district may also need additional approvals.
Will a three season room match the rest of my house?
That is the goal. PLJ frames, roofs, windows and trims the room to match your home's roofline, siding and trim so it looks like it was always part of the house.
