Can I convert my three-season sunroom to a four-season room?

Yes, this is one of the most common conversions we do. We add insulation, upgrade to energy-efficient glass, and connect the space to your HVAC system. The exact work depends on your current setup, but most three-season rooms can be converted.

How much does a sunroom upgrade cost?

Costs vary depending on what you want to change. Simple upgrades like new flooring or window replacements are less expensive than full conversions with insulation and HVAC.

How long does a sunroom conversion take?

Most conversions take 1 to 3 weeks depending on the scope of work. Simple upgrades can be done faster, while full conversions with structural changes take longer.

Common Sunroom Conversions

Here are the most popular types of sunroom conversions we handle in Thousand Oaks.

Three-Season to Four-Season Conversion

This is the most common upgrade. If you have a three-season sunroom that you can't use year-round, we can add insulation, upgrade the glass, and connect it to your HVAC system. This turns your seasonal space into a room you can enjoy every day of the year. Learn more about four-season sunroom features.

Screen Room to Glass Enclosure

If you have a screen room and want more weather protection, we can replace the screens with glass panels. This gives you better temperature control and makes the space feel more like part of your home.

Patio to Sunroom Conversion

Already have a covered patio? We can enclose it with walls, windows, and doors to create a true sunroom. This is a cost-effective way to add living space without building from scratch.

•Insulation Upgrades: Add thermal barriers to reduce heat transfer and improve comfort.
•Window Replacement: Swap single-pane glass for energy-efficient double-pane windows.
•HVAC Integration: Connect your sunroom to your home's heating and cooling system.
•Flooring and Finishes: Update old tile, carpet, or concrete with modern materials.

Why Upgrade Your Sunroom

Upgrading your existing sunroom is often smarter than building a new one. Here's why.

Save Money

Converting or upgrading an existing structure costs less than starting from scratch. You already have the foundation, frame, and roof in place, so you're just improving what's there.

Increase Home Value

A well-designed, functional sunroom is a major selling point. Upgrading an outdated or uncomfortable space makes your home more appealing to buyers and increases its market value.

Use the Space You Have

If your sunroom sits empty because it's too hot, too cold, or just not comfortable, an upgrade brings it back to life. You'll finally get to use the space you already paid for.
