FAQ

Questions before adding more room.

What types of home additions can CAS help with?

CAS can discuss bedroom additions and expanded living areas, including framed tie-ins, exterior envelope work, and finish transitions that connect the new space with the existing home.

How do you connect an addition to the existing home?

The work can include framing connections, exterior envelope details, and finish transitions. The approach depends on the existing home, the proposed space, and the agreed scope.

Will my whole house need to be remodeled?

Not necessarily. The work can focus on the areas agreed for the addition and its connection to the home; a whole-house remodel is not assumed.

Can we stay in the home while the addition is built?

That depends on the project scope and access to the work areas. Discuss how the work may affect day-to-day use of your home with CAS when reviewing the project.

How much will an addition cost, and how long will it take?

Cost and schedule depend on the home, the addition, materials, and the agreed scope. Contact CAS with your project priorities to discuss an estimate and timing.

Where do you work, and how can I request an estimate?

CAS serves Tacoma and Pierce County, including Graham, Puyallup, Spanaway, and Orting. Call or share your name and phone number to request an estimate. Email and project details are optional.
