OnCenter Contracting is dedicated to ensuring that customer satisfaction is our satisfaction. We specialize in interior finishes both in residential and commercial settings and also provide our same exceptional craftsmanship to you home remodeling projects!

"The wood that OnCenter used for my Pergola was defective and they refuse to stand behind their warranty. They tell me that If Menards will not warranty their wood, then how can they. I think it is terrible that I paid $6400 to have a nice pergola on my back patio and I am left with cracked, defective wood. I was told that OnCenter would only replace a portion of the pergola (they could not deny how bad this wood was; but they refuse to replace the entire thing. It is the entire pergola that has the same wood and all of that wood is cracking badly. It will not do me any good to have half of the pergola replaced, only to have the other half keep cracking and be a different color. I tried to explain this to Sam Cox, owner of OnCenter, and he told me that; he cannot control how wood ages; For the money I paid, I really think I should enjoy my pergola and be able to look at it and have my visitors look at it without being ashamed of how unsightly it is. I have a nice house and wanted a nice pergola. I feel I will now need legal representation and have to reach out to Menards corporate office myself. I will have to do the fight that OnCenter should be doing. Terrible"

Window Door Contractors questions, answered by experts

Yes, they can enhance insulation by installing weather stripping and ensuring tight seals.

While doggie doors are convenient for pet owners, they do offer a few drawbacks. For instance, they’re small enough that unwanted critters could come into the house, such as raccoons, snakes, rats, and insects.

They’re also large enough that small children can escape through them, which can be a serious concern to parents of young children.

Finally, doggie doors can make it difficult to regulate your home’s temperature because they constantly let in hot or cold outside air.

A door sill is the horizontal part of the door frame at the bottom, while a door jamb consists of the vertical parts of the frame on either side. The door sill serves as a threshold, sealing the bottom of the door, while the door jamb provides structural support and houses the hinges and latch. Both are essential components of a door frame, with the door sill acting as a transition point and the door jamb providing stability and functionality.

Proper installation ensures solid hinges and locks, maintaining home security.

It’s possible to install a door yourself if the wall opening already exists, but the work is rather complicated, and a professional installation is usually well worth the investment. For your door to work and close properly, you’ll need to shim and level the door frame in your wall perfectly, which can be difficult. Additionally, we recommend you always hire a professional door installer to place an exterior door, as mistakes during the installation process can lead to poor security for your home.
