A sunroom is the bright room you will want to be in all day. Send one request and a sunroom specialist will contact you to talk through size, glass, heating and how the space connects to the house.
Foundation, roofing and glass choices determine whether a sunroom stays comfortable in July and January. Ask about energy ratings and whether the space is meant for three or four seasons.

About sunrooms
Can I use it all year?
A four-season sunroom is built with insulation, glass and HVAC for that. Three-season rooms are not.
Does it need a permit?
Additions generally do. Your partner will help.
Will several contractors call me?
No. Only one contractor will ever call about your request. You will not get a pile of calls and constant emails, and we never sell your information.
Who does the work?
A licensed, independent, insured and vetted partner contractor visits to assess the work, gives you an estimate and does the work if you decide to go ahead. See our Terms of Use for details.
