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."

Whether it's the planned project or the unexpected emergency we pledge to put forth our best effort in a professional and courteous manner. Thank you for considering New Millennium Construction Services Corp.

"Lloyd and James (who did the work) are amazing! We had a pipe burst resulting in having to shut off our water. We called around to see if we could get a plumber or general contractor out to fix it but they were only interested if it was going to be a complete remodel/rehab. One even hung up on me in mid sentence. Lloyd took my call and displayed not only compassion for our situation but a sense of urgency. He explained his basic pricing up front and told us that he would try to get someone out to us in the next hour or so. In less than an hour or so James appeared and introduced himself. After showing him the area of the damage and explaining what happened he was not only able to hone in on where the problem pipe was in the wall, but also why it happened. He gave me different options on how he could handle the pipe repair and why each had its merits. He quickly repaired the burst pipe and got us water pretty quick. Professional, courteous, and capable of explaining trades talk to a novice. I highly recommend this company and I will definitely call on them in the future. Great service, reasonable pricing, and honest work."

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

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.

In the U.S., original and converted carriage houses are most often found in New England, New York, and other parts of the Northeast. New construction carriage houses can be found across the country, and are often added to properties with Colonial-style homes for additional living, storage, or work space, although they can be found in many different styles.

Major home remodeling projects have some of the highest ROI for adding value to your home. For example, adding a primary bedroom can return about 55% of the investment to build. The cost of a primary bedroom suite averages $62,000—-so the high ROI helps sweeten the deal. However, always make sure to speak with a contractor and architect before adding a new room to your home, as each space affects the layout and aesthetic of your home differently.

The number of rooms a guest house should have really depends on your needs. A small guest house might only need one bedroom, a bathroom, a living room, and a kitchen. Larger units may have multiple bedrooms and bathrooms. Your local building codes may limit the number of rooms or square footage you can have in a guest house.

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.
