Frequently Asked Questions
Costs vary by size, style, and whether you choose a 3-season or 4-season design. Most Wisconsin homeowners can expect to invest $25,000 to $65,000. We provide a detailed estimate after your free consultation so you’ll know exactly what to expect.
- 3-Season Room – Built with WeatherMaster windows and lighter framing, designed for spring through fall comfort. Great for fresh air, extra living space, and protection from rain and bugs.
- 4-Season Room – Thermal room walls with high efficiency glass with Low-E argon gas,, so you can comfortably use the space even through all of Wisconsin’s seasons.
Typically any 3-season sunroom or 4-season sunroom that is attached to a house generally requires a frost-protected concrete slab or helical piers to handle freeze-thaw cycles and snow loads common in Wisconsin. There are some options where we don’t need a full concrete foundation, like on a mobile home or a stand alone sunroom.
Yes. A professionally built sunroom adds both square footage and appeal, especially in Wisconsin where outdoor living is limited by weather. Buyers value the added light and flexible living space.
Yes. Outdoor Oasis is fully licensed and insured in Wisconsin. We follow state and local codes and carry full liability and workers’ compensation coverage for your protection.
We offer both a manufacturer’s warranty (covering windows, framing, and roofing components) and a workmanship warranty covering installation and labor. You get complete peace of mind.
We assign a project manager to oversee your build. If an issue arises, it’s addressed immediately, with open communication and quick resolution. We keep the site safe and tidy throughout.
Yes. In nearly every Wisconsin municipality, a permit is required for structural additions, whether it’s a 3-season or 4-season sunroom.
We manage the entire permitting process on your behalf. This includes preparing drawings, engineering (if required), and coordinating with your local building department. It’s included in your project cost.
After permits are approved and materials are ready, installation typically takes 2–6 weeks. From consultation to completion, expect about 8–12 weeks, depending on customization and local permit timelines.
Our crews work weekdays between 8:00 AM and 4:30 PM. We minimize disruption, maintain a clean jobsite, and protect your landscaping and home during construction.
We use engineered roof systems, professional flashing, and high-quality sealants to create a watertight connection. Our installers are trained specifically in transition points between existing homes and new structures.
Flashing is installed to manufacturer specifications and Wisconsin building code. We use durable aluminum flashing and sealant systems designed to handle heavy rain and snow melt.
No. Our 4-season rooms use insulated framing and thermally broken glass to prevent energy loss. For 3-season rooms, we seal carefully to ensure your home’s energy envelope isn’t compromised.
Minimal maintenance is needed. The aluminum framing is powder-coated and virtually maintenance-free. WeatherMaster vinyl windows only need an occasional cleaning with mild soap and water. Seasonal inspections are recommended.
