Meet Our Team
Chuck Wiemann
Owner & Inspector
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.

I am certified through the American Society of Home Inspectors (AHIT), and I get yearly re-certification through the American Society of Home Inspectors (ASHI). 

Lead Inspector
Chris Wiemann
Previous to becoming an inspector, I had the opportunity to gain a lot of experience working for both my dad and with a new home builder for many years.  I also spent a couple of years working for a local excavating company where I did earthwork and gained underground utility experience as well.  My building experience comes from both residential and commercial properties.  Like my dad, serving people and teaching them about homes is my passion. 

I am also certified through AHIT and a member of ASHI. I love to learn and am constantly looking at ways to improve our skills as home inspectors in Des Moines.  

Dave Spratte
Prior to joining Wiemann Home Inspection, Dave was a middle school science teacher for 34 years, using his summers as an opportunity to help a contractor with remodeling homes, roofing and building garages. Dave took his training with AHIT in early 2017 and is also a member of ASHI. 
Brad Koenigsberg
Brad joined Wiemann Home Inspection in early 2019, as a part-time inspector in the Mason City, Clear Lake area. Brad also farms with his brother and worked many summers with a local builder on a variety of building projects. He has done numerous remodeling projects on his family farmhouse.  Brad is also certified through AHIT and a member of ASHI. 
Tim Grogan
Tim joined the Army right out of high school and then the Army National Guard.  He was deployed to Iraq in 2004 and served in combat for 13 months.  After his deployment, he worked as a finish carpenter for a custom home builder out of Portsmouth, NH, doing framing and finish carpentry for 15 years.  He also worked maintenance for a company where his position included HVAC and pool maintenance. His knowledge in the building and remodeling industry has allowed for a smooth transition to home inspection. He is certified through AHIT and a member of ASHI.

Chuck and Julie's niece, Rachael, is the primary voice you may hear when you call to schedule an inspection personally.
