Basement Finishing in Cumming, GA
Our Basement Finishing services
A finished basement should feel like part of your home. Grand Home Design is a licensed, insured contractor serving Cumming. We plan for moisture, egress, HVAC, and sound up front, then build cleanly and on schedule.
Why Cumming Homeowners Choose Us
Moisture Management First
We assess water entry risks, vapor, and humidity. When needed, we address grading, drainage, vapor barriers, sump/pump checks, sealants, and dehumidification before finishes go in.
HVAC, IAQ & Comfort
We plan egress (windows/doors), smoke/CO detectors, fire-blocking, and stair protection as required. Safety isn’t optional.
Code-Compliant Egress & Safety
We size supply/returns properly, insulate, and seal for comfortable temperatures and cleaner air without starving existing systems.
Our Process
-
We confirm goals, head height, utilities, and a realistic budget/timeline. If we see moisture risks, we address them first.

-
Clean job site, dust control, and a single point of contact. Change orders are written with cost/schedule impact before work proceeds.
