FAQ
Common Questions
Get answers to the most frequently asked questions about our services.
A 3-plus-season sunroom is an enclosed space with more insulation and weatherproofing than a basic screened porch, designed to stay comfortable from spring through fall and into milder winter days. It offers far more usability than an open deck without the full mechanical requirements of a four season sunroom.
The difference comes down to insulation and climate control. A four season sunroom is built with full insulation and HVAC integration so it performs year-round in any temperature. A 3-plus-season sunroom is optimised for most of the year and may need supplemental heating during the coldest months.
In most cases, yes. Building permits are typically required due to structural, electrical, and zoning regulations. During your consultation we'll walk you through what applies to your specific project and location so there are no surprises down the line.
The most important decisions involve window performance, roof style, ventilation, and whether you want heating or ceiling fans for added comfort. We'll guide you through every option during your design appointment based on how you plan to use the space.
Every project is custom built to your deck, your home, and your preferences, so costs vary based on size, materials, and configuration. The most accurate way to get a number is to book a free consultation. We'll assess your space and give you a detailed, transparent quote with no obligation.
