A good sunroom brings the outside into your home for everyone to enjoy. You'll be able to get things started on the right foot if you know what you want to do with your space before you start calling contractors. Professionals who build sunrooms will be less likely to add extra fees if you have a clear plan, which means you'll end up paying less to get the exact type of sunny space that you want.
In most states, sunroom contractors need to have general contractor licenses. Ask any contractors who you're considering working with to produce copies of their licenses, and also make sure that they have the right insurance to protect you from financial liability if accidents occur on the job. If a contractor isn't properly licensed and insured, work with a competitor.
Reputable contractors have built dozens of sunrooms, and they're happy to show off their work at every available opportunity. Check up on the reference contacts, and ask them about details that might not show up in pictures such as timeliness, attitude, and reliability.
