Chicago, IL Leak Detection & Building Envelope Consulting
Finding the True Source of Water Intrusion in Chicago Commercial Buildings
Building Envelope Leak Detection in Chicago, IL
In a Chicago building, the place where water appears is rarely the place where it gets in. A wet ceiling on the 8th floor may come from a split sealant joint three floors up, a loose coping at the parapet, or a curtain wall frame that fills with rain during a storm off Lake Michigan. Winter adds another twist. Snow and ice can hide a leak for months, and the damage only shows up during the spring thaw when meltwater finds its way inside. Water can also travel along steel, slab edges and insulation before it drips, so the stain on the ceiling is often far from the cause. Patching where the leak shows up rarely solves anything. The leak comes back, and the hidden damage keeps growing inside the wall. Presto Restoration uses controlled testing and careful inspection to trace each leak back to where it actually starts. With more than 25 years of experience, our team works on Chicago office towers, condominium buildings, hospitals, schools and historic masonry buildings. Once we know the real source, we can fix the problem once, and fix it correctly.
OUR DIAGNOSTIC METHODS FOR CHICAGO BUILDINGS
We choose the testing methods that fit each Chicago building and each leak, so you get clear answers without paying for tests that will not change the repair plan.
The most reliable way to confirm a leak is to recreate it. We spray water on one section of the wall, window or joint at a time, under controlled pressure, while a team member watches the inside. When water appears, we know exactly which part of the envelope failed. This approach works well on Chicago windows and curtain walls, where wind-driven rain off the lake is often the cause. Testing one area at a time keeps the results clear and avoids guessing.
Infrared cameras show temperature differences on a wall or roof surface. Wet areas hold heat and cold differently than dry ones, so trapped moisture often shows up clearly in a thermal image. Chicago weather can work in our favor here. Cold days create a strong difference between indoor and outdoor temperatures, which makes wet insulation and air leaks easier to see. We use thermography to map problem areas quickly before deciding where to test further.
Moisture meters measure how wet a material is, both on the surface and just below it. We take readings across walls, floors, roofs and around windows to map how far water has spread. In Chicago masonry, this helps us see which areas soak up water and are most at risk of freeze-thaw damage. Readings taken over time also show whether a repair has worked and the wall is drying out.
On Chicago high-rises, many failure points sit well above the street and are hard to see from the ground. Drone photography lets us inspect upper floors, parapets, rooftop structures and setbacks closely and safely. High-resolution images reveal cracked terra cotta, open joints, loose flashings and stains that point to hidden leaks. Drone work is also a quick way to survey a building before planning closer inspection or testing.
When other methods cannot confirm what is happening inside the wall, we open it up in small, controlled areas. Probe openings let us see flashings, anchors, insulation and framing directly. On older Chicago masonry and terra cotta buildings, this is often the only way to check the condition of hidden steel anchors and supports. Every opening is documented and then closed and sealed again.
Every diagnostic plan is built around the building and the question we need to answer. A single leaking window in a West Loop loft calls for a very different approach than recurring leaks across a Loop office tower. We select only the methods that will guide the repair, explain why each one is needed, and keep the results focused on what you need to decide next.
How Diagnostic Work Fits Into Your Chicago Restoration Project
Every Presto restoration project in Chicago starts by understanding the building. Diagnostic work is part of that process, so the repairs we recommend are based on evidence instead of guesswork.
Exterior Survey & Leak History
We review where and when leaks appear, talk with building staff, and look over the exterior for likely entry points such as joints, windows, parapets and flashings.
Diagnostic Testing
Targeted water testing, moisture readings and other methods confirm the real cause of each leak before any repair is designed.
Report & Scope
We turn the findings into a clear report and repair scope that addresses the actual causes, with priorities and costs you can plan around.
Restoration Execution
Our crews carry out the repairs, from sealant replacement and flashing work to masonry repair and coatings, during the right season.
Verification & Closeout
Where possible, we retest repaired areas to confirm the leak is stopped before the project is closed out.

Chicago Leak Detection & Consulting FAQs
Does Presto offer leak detection as a standalone service in Chicago?
No. Our leak detection and building envelope consulting are part of complete commercial restoration projects, not a separate service, with a typical minimum project size of $50,000. This keeps our testing focused on what will guide the repair. If you need a standalone forensic study, we recommend a specialty engineering firm.
What methods does Presto use to find leaks in Chicago buildings?
We use controlled water testing, infrared thermography, moisture meter surveys, drone inspection and, when needed, small probe openings. The mix depends on the building and the leak. On Chicago buildings we also look closely at how snowmelt, ice and wind-driven rain off the lake reach the inside.
Why does diagnostic work matter before restoration?
Without it, repairs are often aimed at the wrong place. Water in Chicago buildings can travel a long way inside the wall before it shows up, and winter can hide the damage for months. Diagnostic work confirms the real cause, so the money you spend on restoration actually stops the leak.
Does Presto provide expert witness or litigation support?
No. Presto does not provide forensic engineering, expert witness testimony or litigation support. For that kind of work, we recommend a specialty forensic engineering firm. We are glad to work alongside your engineer or consultant on the restoration once the cause is known.
What does a diagnostic report include?
Each report is built around the specific project. It typically includes inspection findings with photos, the confirmed causes of water entry, testing results and a recommended repair scope with priorities. The goal is a clear plan you can act on.
How long does diagnostic work take?
Most diagnostic work on a Chicago building takes from a few days to a few weeks, depending on the building size and the number of leaks. Water testing needs suitable weather, so some testing may be scheduled for spring through fall, while thermal imaging often works best on cold days.
