Why RMG Interiors

More Than a Flooring Sub.
A Construction Partner.

When a company signs a commercial lease, the clock starts immediately. Landlords have timelines. Business owners have move-in dates. General contractors need interior subcontractors who show up, hit their scope, and don't slow the job down.

RMG Interiors delivers flooring, tile, stone, millwork, and cabinetry for office build-outs and tenant improvements across the Front Range — all under a single contract. Our construction management background means we think like a GC: we read drawings, manage submittals, coordinate phasing, and never wait to be told there's a problem.

The RMG Difference

Why Denver's Top GCs
Choose RMG Interiors

🏗
Construction Management Background

Our principals have managed commercial projects from both the GC and owner's representative side. We understand what a superintendent needs from a subcontractor — and we deliver it without being asked twice.

📅
Schedule-First Mentality

Office TI projects run on hard move-in dates. We build our installation sequencing around your CPM schedule, communicate proactively when conditions change, and don't wait to be told there's a problem.

🔩
Single-Source Finish Package

Flooring, tile, stone, millwork, and cabinetry — all under one contract and one point of accountability. No gaps between trades, no finger-pointing, no GC having to chase three subs for one space.

📁
Professional Documentation

Submittals organized and delivered on time. RFIs written clearly. Closeout packages complete at substantial completion. We run paperwork like a GC, not a trade contractor.

Client Feedback

What GCs & Developers
Say About RMG

RMG came in, read the drawings, and executed without a single RFI coming back incomplete. Flooring, tile, and the millwork package all coordinated perfectly. That's the kind of sub you keep on every project.

General Contractor
Class A Office TI — Denver, CO

We had a hard move-in date and complicated phasing. RMG coordinated with three other trades, worked weekends when needed, and delivered on time. The built-in millwork in the conference rooms is exceptional.

Commercial Developer
Multi-Tenant Office Buildout — Boulder, CO

The submittal package was organized, product was spec-compliant, and the installation was clean across flooring, tile, and cabinetry. Punch list was two items. That's rare.
