TESTIMONIALS

What They Say About Steve Wirtz Builders

"My new kitchen and living room look great! It was great working with SWB. They were professional and made the remodel a positive experience. Their staff was super helpful and I can’t say enough about them. The painter, drywaller, plumber, countertop installer and electrician were also good to work with."

"Starting on June 21st, Steve Wirtz Builders began working on our huse. We couldn't be happier with the work and the time and would absolutely reccomend these guys to anyone that needs work done!!"

"I had the privilege of meeting several employee's of Steve Wirtz Construction company as they replaced an old cellar door... Each person I met I found to be courteous, helpful, dependable and skilled. They are a trustworthy, talented group of individuals with high-work ethics. They arrived on time and left the job site clean after each visit... I truly appreciate all their hard work and kindness! Their skills are A+"
