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!"

With over 20 years of experience in the industry, Promax Construction has the tools to knock out any job for your home or business. We have honed are craft through years of experience and know how to get the job done right. We believe in offering great value to our customers without comprising the quality of the craftsmanship or materials. We cut costs by purchasing wholesale and developing long term relationships with our staff. We are comfortable guaranteeing all of our work. Promax Construction is fully licensed and bonded. Meaning, the customer is always protected under our coverage. When you hire Promax, rest assured the job will be done right with no head-aches. In a tough economy, many homeowners are choosing to save money by hiring independent contractors without the proper licensing and insurance. We do not recommend this practice. Not only do homeowners have no guarantee the job will be done right, they are liable if someone gets hurt on the job. Another example we notice frequently is when a homeowner hires a roofer on the side to repair a roof. 5 years later the shingles are falling off the roof. A quality roof job should last up to 50 years. The homeowner tries to call up the roofer to fix his work and the roofer is out of business, left town, or refuses to honor the guarantee. Save yourself hassle and money by getting the job done right the first time. Licensed. Additional DBA - Promax Construction Corporation. Facebook: https://www.facebook.com/promaxdecatur

FAQs for home building projects in Windsor, IL

One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.

The pros and cons or advantages and disadvantages of building a new house include:

Pros:

  • It’s all new, so you should have several years before you need to pay for major repairs like a new roof. 

  • It’s under warranty, so many fixes within that warranty period should be covered.

  • You get to build the house to your specifications.

Cons:

  • You have to make a LOT of decisions.

  • You will almost certainly deal with building delays.

  • It can take a lot of work to stay within your budget.

  • Building can be more expensive than buying an existing house.

Typically, it’s more affordable to buy an existing home than it is to build a new one. New construction loan interest rates tend to be higher than interest rates for traditional mortgages. Additionally, the cost of materials is likely higher when building a new home than it was when an existing home was built (unless it’s a very new one). You’re also paying for all new appliances, finishes, permits, inspections, and connections for water, gas, and electricity. 

The average price per square foot to build a house is about $150 per square foot. Overall, the cost to build a house ranges anywhere from $100 to $500 per square foot, depending on where you build. The primary cost factors include location, size, and style of house you build.

Hiring a contractor to build your home is a big commitment. So be sure to ask as many questions up front as possible. Here are a few questions to ask a prospective home builder:

  • How many years of experience do you have?

  • Are you licensed, bonded, and insured?

  • Do you have worker’s compensation?

  • How long have you worked with your subcontractors?

  • How do you handle garbage and waste disposal?

  • Do you provide a guarantee or warranty on your work?

  • Do you give free estimates?

  • Do you offer design services?

  • How do you handle change orders?

  • Can you provide at least three references?

  • Can I see some of the work you’ve done?
