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."

Mulligan Restoration Inc. was founded in 1998 and is located in the historic River District of Rockford, IL.

"???? We have been using Mulligan Restoration for more than 5 years. Their quality of work and attention to detail is excellent. They take care of the small details that turn an average job into an excellent job. Rory, the owner, is a personable, easy to talk to person. He stands behind his work. We had an issue come up @ 5 years after he did some work, he took care of it 100%. No charge. Aaron, one of Rory’s key employees, is a first class finish carpenter, no detail is too small. All of Rory’s sub-contractors; plumbers, electricians, painters, etc have been of similar quality. During the work, Rory communicates with the homeowner regularly to keep them appraised of progress or problems. Every effort to lessen their impact on you and your home is taken. Cleanup after the job is great. If you want the job done right the first time, call Mulligan Restoration."

Home Building questions, answered by experts

This answer varies based on where you are, but most states require that all homes are greater than 320 square feet. Remember that four walls are not the only requirements—windows, closet space, minimal ceiling heights, and indoor air quality are also factors. Each state and municipality differs, though, and as some don’t consider tiny homes permanent shelters, you’ll need to check to ensure you aren’t violating any local or state laws with your build.

Some, but not all, home improvements are tax deductible or offer other tax benefits. For example, if you make green improvements to your home, such as installing a heat pump or solar panels, you may qualify for a tax credit. You may also deduct the cost of home improvements you make to improve the accessibility of your home or to allow yourself or another resident to age in place.

The national average cost of a building permit is about $1,600, but this number includes extensive renovations. Homeowners typically spend between $150 and $2,000 in general on one or multiple permits for their project. Conversely, permits for simple projects, such as minor electrical renovations, could cost as little as $10.

How long it takes to build a log cabin depends on a variety of factors, including its size and design, and whether or not you have to clear the land. Construction can take a few weeks for a prefab log cabin on an established site, but up to eight or nine months for a custom cabin on undeveloped land. In comparison, the timeline to build a house is typically four to 12 months.

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.
