At Loos Homes, we stand behind the quality of every home we build. As a long-established home builder in Jefferson County and Southeastern Wisconsin, we are proud to offer one of the area’s strongest warranty packages for new homeowners.
30-Year Transferable Dry Basement Warranty
We are proud to be one of the only builders in the area to offer a 30-year transferable manufacturer dry basement wall warranty, providing lasting protection for your home.
10-Year Insured Builder’s Limited Warranty (Structural Warranty)
Every Loos home comes with an express 10-year insured Builder’s Limited Warranty that provides structural coverage and long-term peace of mind. While most builders will promote their quality, we go one step further and put our promises in writing with an insurance-backed warranty that is also transferable.
We have partnered with Professional Warranty Service Corporation (PWSC) to administer this warranty which is backed directly by Steadfast Insurance, a member of Zurich North America Group. PWSC, a leader in home builder warranties for nearly 30 years, and Zurich, and insurance provider known for its strength, size and quality standards, are proven partners who reflect our level of professionalism, concern for homeowners, and commitment to deliver the very best in home construction and customer service.



First-Year Service Commitment
In addition to the above warranties, we realize that, from time-to-time, there may be some items that are in need of attention. To help provide good service on these items, we offer structured 60-Day and 11-Month submission timeframes during the first year after move-in. By consolidating into these two timeframes, it better allows us to service those items that may require attention.
Additionally, our team professionals in plumbing, heating, and electrical offer 24/7 emergency service in the rare event that would ever be needed!
Thorough Pre-Move-In Walkthrough
Before closing, we conduct a comprehensive final walkthrough with each homeowner. You’ll also receive an organized new home binder containing warranty details, maintenance guidelines, and service procedures for easy reference.
Full warranty terms, coverage details, and limitations are outlined in the official warranty documentation.
