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."

Free computer drafting with general knowlege of design. I have 30 years experience in building houses. I am familiar with local subcontractors. I can get any job done at a reasonable cost.

"The work was done properly and when some additional jobs were added, Mr Grant went out of his way to get subcontractor's in to fix the added jobs promptly. I was very happy with the results and would recommend Steven Grant Construction to anyone who needed a prompt quote and a properly done job. He took the extra steps to finish my job within the quote so I stayed on budget."

Home Building questions, answered by experts

The average build timeline for a home is between six and 12 months, with timelines pushing toward the upper end of that range if you’re creating a custom design or need a lot of land preparation before getting started. Hiring a general contractor or a custom homebuilder will help speed up the process, as you’ll see fewer delays between different parts of the build process getting done.

The steep slope of an A-frame roof withstands high winds, heavy rain, and heavy snowfall, making them popular all over the world. A-frames also offer simple, quick construction. Finally, an A-frame typically has large windows on the non-roof sides to let in a maximum amount of natural light. Consequently, they are often an affordable building solution for the right homeowner and location.

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.

In-law suite floor plans almost always include at least one bedroom, a bathroom, and a combination kitchen/living room area or separate spaces for the kitchen and living room. Larger in-law suites built in accessory dwelling units separate from your main structure can feature multiple bedrooms, dining rooms, and entertainment rooms in addition to the necessities.

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.
