CAT Contracting, Inc. is a national restoration company which operates two divisions. The residential catastrophe division facilitates the sales and restoration processes for homeowners after catastrophic storm events. The Commercial Division services large low slope membrane systems including but not limited to TPO, EPDM, Spray Foam, PVC, Metal and Hydro-Stop

"The original project manager was good. He installed the roof, had a few hiccups, but I was satisfied until 1 1/2 years later when I got 4 leaks. Additionally, some aluminium was supposed to be installed and it still hasn't been installed. I have been calling since March 2019 and still no one has come out to fix the leaks. I only have a couple of months left until warranty expires which I'm figuring they are waiting for. I've called & asked the owner Matt to call me, b ut 5 days later and still no call. A roofer is only as good as his repairs. My advise is don't use Cat. They have no one within 50 miles to repair my roof. I'm very disappointed as I first thought they had done a good job. I had seen reviews where the owner was very responsive, but not to me."

FAMILY OWNED.

"I used this company in 2017/2018 and it was a complete disaster. Some guy named Cord/Coy fail through my roof in 4 spots leaving permanent damage and the repairs were horribly done. They damaged my HVAC and another company had to be paid to come in and fix it. I had to hire another well known roofing company to completely redo the work. The owner was not responsive or involved in communication at all. I live in Urbana il and will gladly provide photos and proof of this horrible experience to anyone that needs it. Stay clear of this company and it's poor practices. BEWARE!"

Home Building questions, answered by experts

The requirement for building permits varies by location, but most building departments will require permits for any changes to the structural components of a home. They’ll also require them for changes to the plumbing, electrical, and HVAC components, as well as any permanent improvements to the land, including concrete patios or foundations for additions or outbuildings. You also might need permits for things like roof replacement and window replacement, depending on your local government.

While a log cabin is often less expensive to build than a typical home, cabins actually have a similar cost per square foot. The main difference affecting price is that log cabins tend to be much smaller than traditional homes. For instance, many cabins are about 500 square feet, versus a traditional house which averages between 2,000 and 3,000 square feet.

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.

The average cost to build a modular home is around $270,000, and most modular homes total between $180,000 and $360,000. Of course, this price varies significantly by location, and the price tends to follow the cost of living in the area. There are quite a few other factors at play that can affect your pricing, including the following:

  • Number of bedrooms and bathrooms

  • Site preparation, including land clearing and leveling

  • Type of foundation

  • Utility connections

  • Cost of building permits

Home additions cost between $22,000 and $84,000, with the average addition totaling $51,000. Project costs can vary greatly depending on the type of addition and the required work to complete it. Homeowners can expect to pay between $80 and $210 per square foot for an addition. Conversions of existing space will sit toward the lower end of that range, while bump-outs and new construction add-ons will push toward the higher end.
