Who We Are & What We Do

We're Weller Infrared Services. We find problems in buildings before they turn into expensive ones.

The company was founded by Mark Weller, a Level 3 Certified Infrared Thermographer (Infraspection Institute credential #8339). That's the highest infrared certification you can hold. Mark's been doing this work for over 25 years, and the company is based in Florida. We serve the entire Southern US — Florida, Georgia, Alabama, South Carolina, North Carolina, Mississippi, Louisiana, and Texas.

What we actually do

In plain terms, we look at buildings with infrared cameras. Thermal imaging shows temperature differences on surfaces, and those differences tell us where things are going wrong. Hidden moisture behind a wall. Air leaking through a window frame. An overloaded circuit in a breaker panel. You can't see any of that with your eyes, but it lights up on an IR camera.

We do building wall infrared inspections, electrical infrared inspections, and roof infrared surveys. We do that from the ground with handheld FLIR cameras and from the air with DJI drones. We also do AAMA/ASTM window water testing, blower door testing, and duct leakage testing.

All of it's non-destructive. We don't tear anything apart to find the problem. That's the whole point.

Real problems, found before they got worse

Last year we got called out to a commercial building in South Florida. The property manager thought one unit had a small roof leak. We flew a drone IR survey after sunset and found moisture trapped in the roof membrane across three separate areas. Two of them weren't leaking into the building yet. If they'd waited another hurricane season, the interior damage would've been six figures. They fixed the membrane for a fraction of that.

Another job, a warehouse in Georgia. The maintenance crew reported flickering lights. We ran an electrical infrared scan on the main distribution panel and found a bus bar connection running 40°F hotter than the others. That's the kind of thing that starts fires. They shut it down, re-torqued the connections, and we re-scanned to confirm the fix.

We've also caught water intrusion behind EIFS (synthetic stucco) on brand new condos, found missing insulation in buildings that passed their final inspection, and documented envelope failures for insurance claims. Every job is different, but the approach is the same: point the camera, read the data, write the report.

Certifications and credentials

Mark holds a stack of certifications because this work touches multiple trades. Level 3 Infrared Thermographer from Infraspection Institute. FLIR Building Science Thermographer (#30937). FAA Licensed Drone Pilot for aerial IR work. Florida Certified Building Contractor. Florida Certified Roofing Contractor. AAMA Certified Fenestration Master for window and door testing. BPI Certified Blower Door and Duct Tester.

Those aren't wall decorations. Each one means we can speak the language of the specific trade we're inspecting: roofing, electrical, building envelope, fenestration. When we write a report, the contractor on the other end doesn't have to guess what we're telling them.

How we work

You call us at (888) 461-1115 or send us a message. We talk through what you're dealing with, figure out which type of inspection makes sense, and schedule the work. Most thermal imaging inspections happen in the early morning or after sunset. That's when the temperature difference between the building and the outside air gives us the clearest data.

We show up, run the inspection, and deliver a written report with annotated thermal images. The report tells you where the problem is, how bad it is, and what to do about it. We don't sell repairs. We don't have a financial reason to find problems that aren't there.

If you've got a building issue you can't figure out, or you want to catch problems before they turn into big ones, that's what we're here for.
