What We Protect
Three pillars.
One partner.
Roof systems, the building envelope and the exterior surfaces around them. When we manage all three, your asset actually gets managed — not stitched together across three vendors.
02 · Envelope
Building Envelope
Façades, glass and exterior equipment maintained with ground-based, reach-system and aerial access.
- Façade & exterior building care
- Glass & window systems
- Solar & exterior equipment
03 · Surfaces
Exterior Surfaces
Stone, concrete, hardscape and pavement cleaned, restored, sealed and maintained on a documented schedule.
- Stone, paver & travertine
- Concrete & hardscape
- Parking & pavement
Our Core Systems
Proprietary systems.
Predictable outcomes.
Every CLN system follows a defined pathway from assessment and cleaning through restoration, treatment and ongoing protection. Select the exterior system to explore its primary treatment pathways.

The Problem
Sound familiar?
- Roofs staining and aging years before their rated life.
- Facades stained by Gulf Coast humidity, salt air and organic growth.
- Parking lots and garage decks aging faster than the building itself.
- Three vendors, three invoices, and nobody accountable for the whole asset.
The Clean Stream (CLN™) Answer
We manage the whole envelope.
- Condition assessments — often drone-mapped — before we quote a dollar.
- One crew, one schedule, one accountable partner for roof + envelope + surfaces.
- Methods engineered for Gulf Coast humidity, salt and heat cycles.
- Documented outcomes that raise appraised value and pre-listing appeal.
