Our inspectors are trained and certified through AHIT (American Home Inspectors Training and earn yearly CEUs through the American Society of Home Inspectors (ASHI).  We’ve performed cumulatively over 3000 inspections; and our inspectors have years of experience in building, and have spent months training alongside Chuck and Chris, our lead inspectors. This means you, our home buyers, will know you are getting a top-notch home inspection.

“I graduated from high school knowing I wanted to pursue work in the building trades. I was privileged to learn under a highly-regarded Des Moines-area home builder who taught me how to build quality homes and to treat customers right. I spent 20 years in new home building.  Ongoing customer service and excellence remain the cornerstone of my business today.

Previous to starting my home inspection company I ran Wiemann Remodeling with my son, Chris. Our Des Moines area home inspection company stemmed from numerous customers asking me to inspect their homes in preparation to sell.  They also regularly consulted with me regarding problems encountered after moving into a home.  As a result, I felt a strong desire to provide people with honest, skilled inspections and to make scheduling an inspection as simple as possible. For me, it’s all about treating people right.

My wife, Julie and I have two children who are married and three grandchildren! We worship at the Ridge in Ankeny where we are both involved in serving in a variety of ways. My hobbies include home projects and spending time with family and friends.

“I’ve always loved building things and working on houses. At a young age I started helping my dad work and do projects around the house. When I was in high school I took a two year remodeling program at Central Campus and through our church participated in multiple working mission trips to help remodel and rebuild communities in several different states.

I had the opportunity to gain a lot of experience working with a new home builder in the area for a couple of years, and then helping run our family remodeling business for several years.  My building experience comes from both residential and commercial.   Like my dad, serving people and teaching them about homes is my passion. 

My wife Amanda and I have three children. We live in Urbandale, worship and serve at Lutheran Church of Hope-Waukee, and I enjoy working on home projects, flipping some properties, golf and spending time with my family. I love to learn and am constantly looking at ways to improve our skills as home inspectors in Des Moines.”

I love to teach, having also taught driver education for several years, and enjoyed many successful seasons as a cross country and track coach, where I was fortunate enough to coach on three state championship teams. I have always done building as a hobby and often get asked to do remodeling projects for family and friends.  I enjoy being a home inspector so I can continue educating as a profession. I especially enjoy working with first time home buyers.  I have seen how Chuck, Chris, and their team provide excellent customer service and am committed to doing that as well.

My wife Nancy and I have three children and three granddaughters.  We attend Ankeny FUMC. My hobbies include spending time with family and friends, landscaping, home projects, and following the Iowa Hawkeyes. Go Hawks!”

“From the time I was young, and because I started farming with my family immediately out of high school, I’ve always been handy and interested in learning.  For many summers I assisted a local builder with a variety of projects to help supplement farming income.  Additionally, remodeling our old farmhouse has been a constant “past-time” for my entire adult life.  In many of my projects I gleaned valuable information from my brother-in-law Chuck and nephew Chris.

My wife Mary Jo and I have two married children, as well as three grandchildren.  We live in Sheffield, Iowa;  worship and serve in a variety of leadership roles at Rolling Acres Church in Mason City.  I enjoy working on home projects, golf, and spending time with my wife and grandkids.” 


Tim Grogan, Inspector

“I was born and raised in York, Maine and joined the Army right out of high school and then the Army National Guard.  I was deployed to Iraq in 2004 and served in combat for 13 months.  After my deployment, I worked as a finish carpenter for a custom home builder out of Portsmouth, NH, doing framing and finish carpentry for 15 years.  I also worked maintenance for a company where my position included HVAC and pool maintenance.  I most recently worked as a drafter for a local architecture firm, but my passion for and knowledge in the building and remodeling industry has allowed for a smooth transition to being a home inspector. 

I live with my wife and two boys in Clive. We attend Eternity Church in Clive.  I enjoy spending time with our family outdoors and serve as a leader with my son’s boy scout troop.”
