What we do
We handle upgrades to leased and owner-occupied commercial spaces, including layout modifications, millwork, finishes and services coordination. We work with owners, property managers, architects and general contractors, and we are used to working in spaces that stay open.
How we work
Whether the job is a tenant improvement before move-in or an upgrade to an active facility, we phase the work around your operations. Our restoration of a refrigerated distribution facility, for example, was phased so the loading dock kept operating.
What is included
- Layout modifications and new partitions
- Millwork and finishes
- Concrete and loading dock work
- Ceilings, flooring and painting
- Services coordination with mechanical and electrical trades
- Back-to-base restoration for tenant turnover or redevelopment
