Sunroom Addition Cost Estimates

Screen rooms are spaces that are enclosed by screens rather than windows and most often used spring through fall. If you are looking for a solution that will keep the bugs away without breaking the bank, a screen room would be a good choice for you.

Three-season rooms are enclosed with windows, often floor-to-ceiling, on one to three sides of the room. These rooms are also most often used in spring, summer, and fall. Three-season rooms are not climate-controlled so they can get chilly in the winter and hot in the summer if you don’t have good-quality sunroom glass. The benefit of a three-season room over a screen room is that the room and its contents are protected from rain, dust, and any other nature that might try to blow in. If you want full protection from the elements and want a less expensive alternative to a year-round room, then a three-season room would serve you well.

Four-season rooms are enclosed with windows just like three-season rooms but they can be climate-controlled, making them comfortable to use all year round. Four-season rooms can also be called all-season or year-round rooms. If you want to be able to comfortably use your sunroom year-round, then a four-season room is what you will need.

This means that the sunroom is going to be built under an existing roof, such as a porch. Under existing rooms can be screen, three-season, or four-season sunrooms. Many times, these projects are replacing wood screen rooms that have succumbed to the elements.

Double-paned glass with low-emission gas between the panes offers better insulation to keep the heat out in the summer and in during the winter. Not all double-paned glass is the same however, so make sure you ask about the details of the glass that your contractor uses.

For example, here at JSB, double-paned glass is standard in all of our three-season. Aluminum three-season rooms use LoE Argon gas-filled windows to reduce the amount of heat that goes in or out through the glass.

Cardinal 366 insulated glass is a silver-oxide LoE insulated glass. This type of window makes a four-season room energy efficient so that it can be climate-controlled with heat and A/C.

JSB’s BetterLiving sunrooms come with a 50-year transferable warranty from BetterLiving. This manufacturer warranty will cover issues that arise from faulty materials. The transferable nature of this warranty means that if you sell your home, the warranty will transfer to the new owners.

We also put our limited lifetime craftsmanship warranty on all of our sunrooms. Our sunroom installers are all trained and certified by BetterLiving so our craftsmanship warranty covers issues that arise from improper installation of the materials.

The color of your sunroom most often matches the trim of your home or compliments your home’s color to make it a seamless addition to your home. There is some price difference between the color choices.

Screen and Three-Season rooms have a powder-coated paint finish that comes in white, desert sand (tan), and earthstone (dark brown). You can also choose for the inside of your sunroom to be white with any of these exterior colors. White interiors tend to make the room feel larger and compliment the interior of the home as well.

Four-season vinyl rooms can be white or desert sand. The dark earthstone color absorbs too much heat from the sun to be used with the increased insulation of a four-season room. You can also choose for the interior to be white with either exterior color.

We will install sunrooms on a concrete pad, a pressure-treated wood deck or a composite deck. If you already have a foundation, your JSB design consultant will be able to evaluate its condition to make sure it is suitable for your sunroom.

If you don’t currently have a foundation, that will be part of your project. You can either add it to your contract with JSB or we can recommend someone to install your foundation separately. Then we will build your sunroom once the foundation is completed.
