About Us

Rebuilding Together Sheboygan County 2011

Here's the project we worked on for Project Day 2011. It was a combined effort between Wells Fargo (primary donor) along with the Sheboygan Downtown Rotary and the Sheboygan Early Bird Rotary clubs. We also had invaluable help from Quasius Construction and Showcase Painting. The results are remarkable. The scope of the project was to replace 57 windows, 4 exterior doors, painting the common areas including the hallways, living room, kitchen/dining room and finally the daycare center. We accomplished all of that plus replacing the toilet and vanity in the daycare center, re-staining the exterior woodwork on 3 sides of the building, yard clean-up, and painting the playground equipment.

We had help from the Sheboygan North and South High School Interact Clubs along with the Sheboygan North carpentry trade group. Seeing all of the young people helping really was uplifting! We want to thank all of those that were able to help. Every little contribution really made the project come together.

The Bridgeway House is part of the Sheboygan County Interfaith Organization. It is a group transitional home for single mothers and their children to use while they transition from "crisis" situations to working their way back into the community. This is a structured, goal oriented, facility where each family is responsible to learn the life skills they will need to grow their self-esteem and commitment to the community. This project has helped tweak the interior and most definitely help reduce their utility bills in the future.

History of 4-Square Home Inspections

After graduating from Tri-State University in 1985 with a Bachelor of Science Degree in Mechanical Engineering, my career brought me to Wisconsin. When the companies I worked for started moving out of the State or were sold I became a displaced worker. I turned my search locally for the benefit of my family who made Sheboygan their home.  My wife, a Real Estate Broker, knew my skills and my desire to help people. She suggested I become a Home Inspector.  I went to the National Association of Certified Home Inspectors (NACHI) and passed their Home Inspector exam where 60% of the participants fail. I obtained my credentials from the State of Wisconsin and launched our business, 4-Square Home Inspections, LLC on April 25, 2006.

Our business has continuously grown by providing superior customer service and thorough inspections at a competitive price. We’ve received so many wonderful reviews from our clients thanking us for the job we did for them and helping them learn more about the biggest buying decision they will most likely make in their entire life, their Home.

We’re constantly improving our skills and services to be a one-stop shop for anyone in need of an inspection or testing of their home. We perform Residential Home Inspections, Commercial Inspections, Pre-Listing inspections for Sellers, and Home Maintenance Inspections for people who want to make wise choices to protect their investment. We've expanded our services to include Radon and Mold testing, and we've achieved our credentials as a Wisconsin Uniform Dwelling Inspector (Construction Building Inspector) and Lead Abatement Supervisor.

A 4-Square Future

By Bob Petrie Sheboygan Press staff

Greg Liebig started 4-Square Home Inspections in Sheboygan three years ago out of necessity. After being laid off as an engineer at Watry Industries, Liebig had no job, no severance package and no new prospects in the engineering field.

"We started looking at careers in my field and around here, but it was slim pickings and nothing was really available at all," Liebig said.

Unemployment was running out, and with Liebig's wife, Theresa Christen-Liebig, going to college and their children still living in the Sheboygan area, Greg said, "We really didn't think relocation would be in the best interest of the kids."

After looking at several career possibilities, including opening a catering business, Greg and Theresa landed upon the idea of opening their own home inspection business.

Theresa had been working in real estate in Cedar Grove and knew a few contacts to get them pointed in the right direction. There weren't many home inspectors in the phone book, so there was room in the market. And they thought it would be a good fit for Greg.

"We had a little bit of an advantage when we started out ... and I knew full well Greg was certainly capable of being able to do a good job for people," Theresa said.

Greg, who considers himself pretty handy around the house, took a state home inspectors test and passed, and then a national test in Green Bay to earn his license, and in 2006 opened 4-Square, which operates from the couple's Sheboygan home at 419 Erie Ave.

The couple had to make some pretty big sacrifices to make the business happen. They borrowed money from their parents, sold a vacation cottage on Crystal Lake and parted with their Honda motorcycle for the cash needed to open.

"I couldn't very well put ladders on my Gold Wing," Greg said.

Business was slow at first; building a clientele took its time. Theresa's contacts in real estate got Greg in the door, and he took a thorough approach to his new career, applying many of the things he learned in engineering and manufacturing to create a business plan.

"I'm very big on goal-setting," said Greg, 45. "So when we started out the business we set some realistic goals and stayed focused on what's important, and made sure we had enough capital to get things going."

Slowly, 4-Square has grown, even in a difficult housing market. Roughly 60 percent of his clients are first-time homebuyers, and Greg said he prides himself on being meticulous in going through a home, to make sure the new owners know exactly what needs to be fixed, but also how to maintain the key

components of the house for comfort and safety.

"If you don't do things right, it affects a lot of people," Greg said.

Among his recent clients were Ray and Sara Miller, first-time buyers who are in the process of purchasing a home on North 28th Street.

"He did a real nice job; it was very thorough," said Ray Miller, 32, of 4-Square's inspection. "He really walked us through the house, and his inspection report was almost like a how-to guide to owning a house."

Theresa, 48, who earned her master's degree in counseling at Lakeland College, works part time in real estate and also makes the appointments and does the marketing for 4-Square.

The company has a Web site ( which they say has been effective at bringing in clients, but it's the telephone (the business number is 451-4646) that she considers extremely crucial to the success of business.

"If you don't answer the phone, and you're not there to take care of people right away, they'll go to the next person on the list, and you might lose the opportunity," she said.

The couple recently held a thank-you picnic for their customers, with about 80 people turning out. "We're turning the corner," Theresa said. "The first two years is a difficult time in any business." Greg, who had been laid off from other engineering jobs at Tecumseh and Polar Ware in addition to Watry, offers the following positive advice to people who may also find themselves out of work and looking for something new for a career.

"Regroup," he said. "Step back, regroup, think about different options. Don't get so distressed when it comes to having to make a change in your life. Stay positive, stay focused."

Said Theresa, "It's a scary time when you lose your job and you don't know what's going to happen. But try not to lose perspective as far as letting it overwhelm you so much, and focus on moving forward."

Greg said that he really likes his new career, which is very important, especially after going through a career-changing event.

"That's the biggest thing to get across," he said. "Once you go through the sad phase of losing your job, you just stay positive and look forward to something you really enjoy doing. If you're in a situation where what you did before is no longer there, you're going to need to do something to survive. Why not pick something you'd really like to do?"

Obligation of an Engineer

I am an Engineer. In my profession I take deep pride. To it, I owe solemn obligations.

Since the Stone Age, human progress has been spurred by the engineering genius. Engineers have made usable nature's vast resources of material and energy for Humanity's [Mankind's] benefit. Engineers have vitalized and turned to practical use the principles of science and the means of technology. Were it not for this heritage of accumulated experience, my efforts would be feeble.

As an Engineer, I Gregory Liebig pledge to practice integrity and fair dealing, tolerance and respect, and to uphold devotion to the standards and the dignity of my profession, conscious always that my skill carries with it the obligation to serve humanity by making the best use of Earth's precious wealth.

As an Engineer, in humility and with the need for Divine guidance, I shall participate in none but honest enterprises. When needed, my skill and knowledge shall be given without reservation for the public good. In the performance of duty and in fidelity to my profession, I shall give the utmost.

SHEBOYGAN, WI, June 11, 2008: 4-Square Home Inspections, LLC announces that Gregory Liebig earns the Credentials as a licensed One and Two Family Dwelling Construction Inspector.The Uniform Dwelling Code (UDC) is the statewide building code for one- and two-family dwellings built since June 1, 1980. The UDC is a uniform statewide code that sets minimum standards for fire safety; structural strength; energy conservation; erosion control; heating, plumbing and electrical systems; and general health and safety in new dwellings.

  • There is enforcement of the UDC in all Wisconsin municipalities. The following are not covered by the UDC:
  • Dwellings built before June 1, 1980 or additions and alterations to such dwellings.
  • Mobile (manufactured) homes which are instead subject to Federal standards.
  • Multi-unit (three or more) residential buildings which are regulated by the State Commercial Building Codes
  • Detached garages or accessory buildings.

A Home Inspection as defined in the Wisconsin Standards of Practice is NOT a code inspection. Most homes in our area would not be covered by the UDC simply because of the age of the home.

Greg Liebig, owner of 4-Square Home Inspections, LLC has Bachelor of Science Degree in Mechanical Engineering and over 25 years of home improvement experience. My purpose is to educate you on the features of your home, show you items that can be improved, and point out significant problems that will need to be addressed. 4-Square Home Inspections, LLC provides quality home inspections throughout Sheboygan County and Parts of Ozaukee, Fond du Lac, Calumet, and Manitowoc Counties.
