RENOVA Contractors LLC takes a hands-on, full-scope approach to basement remodeling in Seattle. We start with a walkthrough to measure the space, check structural elements, and discuss layout options. If the project involves egress, structural work, or ADU planning, we coordinate with licensed engineers or architects early.
From there, we build a clear line-by-line estimate and submit all required permits to the City of Seattle. Materials are ordered up front, and we manage every trade — framing, electrical, plumbing, HVAC, insulation, drywall, flooring, and finish work — in sequence. You’ll work with the same crew start to finish, with no rotating subs or missed steps.
Our team walks every inspection, keeps the jobsite clean, and finishes with a full walkthrough and labor warranty. We don’t cut corners — we build it once, build it clean, and build it to code. ✅
We don’t use cheap stock or bottom-shelf materials. Every basement we remodel in Seattle is built with code-compliant products that are rated for moisture, structure, and long-term durability.
