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

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.

Framing tends to be the longest step in the construction process, especially for larger homes. It takes anywhere from one week to a couple of months, depending on the house size, the number of people on the construction crew, and the time of year. The design stage often takes a long time, too. Some people spend months or even years contemplating their house’s size, layout, and materials before construction begins.

Prefab kits like a small sunroom for around $20,000 or even a basic gazebo roof for as little as $60 can save you big over professional installation. However, you lose the option for customization, and these structures tend not to last nearly as long. As for bigger projects like a deck or patio, you shouldn’t go with the DIY route unless you’re fully prepped with the tools and know-how to get it done right. Mistakes can be frustrating and costly, so choose a pro if you’re looking to eliminate your risk of error.

Yes, you can finance cottage construction through several options. Construction loans provide funds in stages as work progresses, while home equity loans or lines of credit are available if you have existing property. Some lenders offer a combined construction and permanent mortgage. Always review loan terms and payment milestones before committing.

Construction typically takes 1-3 weeks, depending on the project’s scope and customization.
