"Great job and great warranty."
Michael, Milwaukee, WI
Roofing and Gutters

"Needed to have windows replaced in my 80 yr. old house and called several companies for esitmate. While Sigma was not the cheapest, they gave 3 levels of quality windows, left estimates, were professional and there was no high pressure sales pitch. A few finishing issues which I put in writing to them. They were responsive to that and inspected and agreed with my assessment stating not up to their standards. Ordered 11 more windows for install (in the process). Took care of two of the fall issues and will return to finish up outside trim and complete final fall install issues. Clean up was excellent and took care not to damage new plantings in front of house. Have six windows to go and will use Sigma. Explained anything that needed to be done, such as blinds removed and how long to wait before rehang to allow caulk to set."
Nancy, Milwaukee, WI
Windows

"The price was good compared to others. They gave us an estimate. They did a follow up on the work they did. They cleaned any mess they made. They were friendly."
William, Milwaukee, WI
Masonry

"It was an excellent experience. We went with them because the guarantee and because of the service they provided. They sent someone out and sat with us just ahead if their crew and discussed everything that was going to happen over the weeks that they were going to be here. They talked with us at the end of everyday and let us know what they had done and did excellent clean up. They also replaced a small attic window and one built an aluminum window and installed it. They also had to replace the gutter. They did a great job and I was surprised with how much interaction they had with us before they started the job and the care they took. They had to come into the house to install the attic fan and the dog was here and it did not have any problem with him and he did not have a problem with it, which was unusual."
Mark, Milwaukee, WI
Roofing and Windows

"Most times I find it hard for home improvement contractors to return my calls. In my opinion, the mark of a good contractor is the prompt return of phone calls, usually within 3 days for me. Sigma met that expectation. Secondly, it's how a company's job planner/representative takes the time to explain the products or services the company promotes. Again, Sigma met that expectation. My experience with Sigma was very positive. I won't hesistate to call for future projects. Regards!"
Michael and Ione, Kansasville, WI

Thad, Racine, WI

"Prior to your roofing, I had 2 other companies. By FAR, your staff did the best all-around job from managers to men on the job. You had some unique ideas for the trim around our 11 upper windows. Keep up the A # 1 quality and service."
Ray and Ellie, Hales Corners, WI
Roofing

"We were very concerned about protection for our plants in the areas near construction. It turned out that not one single plant was damaged. In fact, you could not even see any evidence that work had been done or that anyone had even been here except a new roof was in place. Please pass along our thanks and appreciation to everyone involved in the project. The whole team did an excellent job."
Gordon & Lynn, Sussex, WI

"We appreciate Sigma jumping through the many hoops required by the city."
Sue & Al, Milwaukee, WI
Roofing

"Our house, that we built in 1968-69, is 40 years old. Prior to your roofing I had two other companies. By FAR, your staff did the best all-around job from managers to men on the job. You had some unique ideas about the trim around our 11 upper windows. Actually, I picked your company out of the Yellow Pages, Great Choice. Keep up A#1 quality and service."
Ray, Hales Corners, WI

"Melody & I are extremely happy with our selection of Sigma Exteriors as our roofing contractor. With great delight, we spent times of Summer and Autumn rains inside, knowing that nothing was coming into our house. And! Watching the rain flow through the new 5 inch gutters and 4 inch downspouts away from the house was assuring. When Winter came, and snow and ice built up on the roof, we had no worry of ice dam damage. We spent a lot of money, but it was money well spent!"

"In October of 2001 my roof was damaged by a horrible hail storm. For four months I searched for a contractor, and finally I found Sigma Exteriors. From the first contact to the last tool being put away, the experience was nearly pleasureable. The crew showed up on Thursday, February 7th, and had the house re-roofed by 3pm. They were done the next day by 5pm. When they left they had removed all the debris, and I mean ALL the debris. I have nothing but good things to say about all the guys in the crew. They had to be the friendliest and most polite bunch of highly skilled workers I've seen. Sigma Exteriors is my best reccomendation to anyone."
James, Brookfield, WI

From the time I met Matt, received his proposal, and had the crew on the job it was an excellent experience. We had our old roof torn off, and even then, the men did a clean job. I was skeptical because I did not have a personal reference, but anyone who needs one, call me."

"I had a new dimensional roof put on our home April 10th, 2003. I would like to thank you and your crew for doing a great job. All the men were very courteous and respectful for me and our property. From the time I met Matt, received his proposal, and had the crew on the job it was an excellent experience. We had our old roof torn off, and even then, the men did a clean job. I was skeptical because I did not have a personal reference, but anyone who needs one, call me."

After many years of failed roof repairs by other contractors, your company was finally able to fix the problem. Phil Oresick was exceptional; finding the problem, recommending a solution, and communicating the process to me and my parents. The roof project has now been completed, and my parents were impressed with how hard the roofers worked and the care they took to clean up. Thanks so much to Phil and the crew."

"In October of 2001 my roof was damaged by a horrible hail storm. For four months I searched for a contractor, and finally I found Sigma Exteriors. From the first contact to the last tool being put away, the experience was nearly pleasureable. The crew showed up on Thursday, February 7th, and had the house re-roofed by 3pm. They were done the next day by 5pm. When they left they had removed all the debris, and I mean ALL the debris. I have nothing but good things to say about all the guys in the crew. They had to be the friendliest and most polite bunch of highly skilled workers I've seen. Sigma Exteriors is my best reccomendation to anyone."
James, Brookfield, WI

"I find Sigma Exteriors to be one of the most professional business's I have worked with. Sigma has been there when stated, given competitive bids, the work site is clean, the crew professional and respectful. Sigma Exteriors has been an enjoyable company to work with and plan to have them around for many more of our roofing needs."
