The network your building deserves — installed once, done right.
STLCertWorks builds structured cabling systems for hotels, offices, warehouses, and retail across the greater St. Louis region. Certified copper. Clean closets. Documentation you'll actually use.
Businesses hire us because we take the details seriously.
Cabling is invisible when it's done right — and impossible to hide when it isn't. Our reputation is built on the parts other contractors skip.
Standards-Based Installations
Every run is installed to BICSI and TIA best practices — pathways, bend radius, terminations, the whole book.
Thorough Documentation
You get labeled ports, as-built drawings, and certification reports on delivery. No missing pieces later.
Safety First, Always
OSHA-trained crews, proper PPE, ladder safety, and hot-work coordination baked into every job site.
Reliable Communication
One project lead. Daily updates. A phone that gets answered. Straight talk from bid to closeout.
Structured cabling — the full stack.
From single-drop MAC work to multi-floor rewires, we handle the physical layer so your IT team can focus on everything above it.
Cat5e / Cat6 / Cat6A Installation
New drops, additions, and full building rewires — copper cabling engineered for the next decade of throughput.
Certification & Testing
Fluke DSX certification with permanent-link and channel test reports handed off with the project.
MDF / IDF Cleanup
Legacy closets brought current: retermination, vertical management, patch panels, labeling, and documentation.
Cable Auditing & Documentation
Full-plant walkthroughs to identify abandoned cable, mislabels, and code exposure — with a report you can act on.
Trusted across commercial verticals.
Every industry has its own cabling reality — occupied hospitality corridors, active warehouse floors, and high-traffic retail spaces. We know the difference.

- Consistent labeling schema on both ends
- Vertical & horizontal cable management
- Color-coded by service and floor
- As-built drawings delivered at closeout
