From one cracked panel on a rental unit to a complete multi-building commercial siding replacement, Squared Siding covers every Siding Contractor need in Downers Grove, IL with the same professional standard.

Not every siding situation in Downers Grove, IL requires a full replacement, and a contractor who tells you otherwise without thoroughly assessing your existing system is prioritizing their revenue over your best interest. Squared Siding's repair crews are trained to diagnose what your property actually needs - whether that is a targeted panel replacement, a caulk restoration at window transitions, a rotted corner board, or a moisture source fix that needs to happen before new material goes over it.

We handle the complete insurance process - initial damage documentation with photos and measurements, adjuster coordination and site walks, scope review against Xactimate pricing, and supplement filing when initial settlements undercount the legitimate scope of work.

The windstorm last fall knocked a full section off the back of our house. I called +1-844-782-0929 late on a Sunday and was connected to a live dispatcher who scheduled a crew for Monday morning. The damage was stabilized Monday, the insurance adjuster came Thursday with the crew there, and the full repair was done the following week. I did not have to manage any of that process - Squared Siding handled the adjuster coordination and delivered the documentation. Exactly what you need when your house is exposed.
My insurance adjuster's initial estimate was low enough that I would have had to pay significantly out of pocket for a proper replacement. Squared Siding's project manager reviewed the settlement, documented additional damage that had not been counted, and filed a supplement claim that added over four thousand dollars to my settlement. The final repair cost me exactly my deductible. That kind of experience with the claims process is worth a lot.
The crew treated the job site like it was their own yard. Debris contained every day, cleanup done before leaving, and a magnet sweep around the perimeter before they packed up on the last day. That level of respect for the property is something I noticed because I was not expecting it after previous contractor experiences in Downers Grove, IL. The siding itself is beautiful and the workmanship at every corner and trim joint is tight and clean.
We had a significant amount of wood rot behind the siding on the north face of our house that previous contractors had covered over without addressing. Squared Siding's crew identified it during the inspection, showed me the extent of the damage on camera before quoting the additional repair work, and gave me the choice of how to proceed. Everything was documented in writing before any additional work started. That transparency is what differentiates a contractor you can trust from one you have to monitor.
