Flooring Is Installed to Instructions
Flooring manufacturers publish detailed installation instructions covering substrate flatness, moisture testing, acclimation, adhesives, fastening, expansion space and transitions. Many warranties depend on following them. Most flooring disputes therefore turn on whether the installer followed the instructions that applied to that product, and whether the substrate was ready to receive it.
As a General Foreman at O'Hare, Paul oversees inspection and maintenance of flooring systems in terminals and concourses, and he has supervised flooring installation and accessibility modifications on commercial and educational projects.
Flooring Conditions Paul Evaluates
| Condition | Possible causes Paul considers |
|---|---|
| Cupping, crowning or gapping in wood flooring | Moisture, acclimation, expansion space, substrate |
| Cracked or loose tile, hollow sounds | Substrate movement, coverage, setting materials, layout |
| Seams opening in resilient or laminate floors | Substrate, adhesive, temperature, installation |
| Lippage and uneven transitions | Substrate flatness, setting method, layout |
| Squeaks and deflection | Subfloor fastening, framing, installation |
The table lists possible causes only. The cause of a specific condition is determined from the evidence, following the method on the workmanship analysis page.
Thresholds, Transitions and Doors
Thresholds and transitions sit where flooring meets other materials, and they are a frequent source of complaints and trip concerns. Paul evaluates their selection, height, fastening and alignment with the door and frame. He also evaluates door installation and hardware in relation to the finished floor, because a door that binds on a new floor may reflect the floor installation, the door hanging or both. Where accessibility requirements apply to a threshold or transition, he can address the installed condition against the applicable requirement.
Fixtures and Accessories
Fixtures and accessories, such as toilet partitions, grab bars, shelving, counters and furniture installed by the contractor, depend on backing, fastening and layout. Paul evaluates whether they were installed in the location shown, secured to proper backing and finished cleanly. He does not offer plumbing or electrical engineering opinions. See framing and carpentry for backing and blocking.
Moisture and Site Conditions
Many flooring failures begin before the first board or tile is installed. Concrete that has not dried, a building that is not yet conditioned, or materials delivered too late to acclimate can all lead to problems that look like poor installation. Paul reviews the schedule, site conditions and any moisture testing records to see whether the floor was installed when and where the manufacturer's instructions allowed.
