Certified Professional Inspector and licensed contractor serving all of southwest Minnesota and Eastern South Dakota

Inspected Once, Inspected Right! ®

A home is the biggest purchase you’ll ever make, so it’s important to understand the condition of your investment. Let 4K Construction provide you with a thorough inspection and report you can rely on.

My name is Kerry Louwagie and I’m a Certified Professional Inspector®. I’ve been trained by InterNACHI, the International Association of Certified Home Inspectors, and I represent the most highly qualified property inspectors in the industry.

I’m also a South Dakota registered home inspector. License # 16840

I’m also a fully insured Minnesota-Licensed Building Contractor (#BC638118), so I know homes inside and out. I can spot problems with materials, installation and workmanship that inspectors without my background and experience might miss.

I use a state-of-the-art thermal imaging camera as one of my standard inspection tools so that I can pinpoint problems that can’t be seen with the naked eye. Ask me about a free Home Energy Report™ with your inspection to help you quickly determine ways to save energy and money right away. I also offer Radon Testing to make sure your family is safe.

Whether you’re a home buyer, home seller, real estate professional, investor or lender, let 4K Construction LLC educate you about your home so that you can make an informed and confident decision.
