FREE Warranty Coverage & Simple Warranty*

90 Day Warranty

We back all of our residential inspections. A 90-Day Limited Structural and Mechanical (10 years and newer) Warranty with a ZERO deductible applies to the residential home. Zero deductible for qualified repairs.

Platinum Roof Protection Plan

Covers repairs for leaks on the residential roof for a period of 5 years from the date of the inspection. This includes all residential roof types, including asphalt/composition shingles, slate roofs, metal roofs, tile roofs, and non-commercial flat roof types. This warranty applies to the home itself, and specifically excludes other structures. $3,000 aggregate coverage. Deductible applies.

Mold Safe

Covers any New Visible Mold in the home that was not there at the residential inspection without doing a mold inspection. Up to $2,000 coverage for remediation of the new mold. Deductible applies.


Covers underground Water Lines and Sewer/Septic Lines for failures to the line. The 90 Day coverage may be extended to 6 months if a sewerscope was done with residential inspections and there were no issues at that time. $4,000 aggregate. Deductible applies. May be renewable.


We match appliances against the national database to see if there are any outstanding/potential recalls for their household appliances. 1 in 10 homes has a potential recalled appliance and they are usually a fire hazard.

Radon Protection Plan

Covers the home buyer when there is a radon test done and the test comes back at a safe level of 3.9pCi/L or below. If a 2nd test is performed after the original test within 120 Days, and the new test is at an unsafe level then this policy pays up to $1200 for a mitigation system to be installed in the residential home. Deductible applies.

    I can't say enough about this company but I will definitely try! They were recommended by my realtor, whom I trust and after doing my own research decided to hire them as part of our home buying journey. The inspector (Eric) 😊 was … More amazing! He was thorough, knowledgeable and walked us through each part of the process. I felt that he truly looked out for our best interest and and the investment of purchasing a home. He made this part of the process easy for us and offered professional support and knowledge. I would absolutely use this company in any future endeavors that we encounter and will be recommending them to family and friends.

    When purchasing our house we are so thankful to have had Jack Rothweiler and Liz Rothweiler by our side during the process with Castle Home Inspections. They were easy to get ahold of, friendly, timely, and most importantly trustworthy … More and dependable. They not only complete their job duties but go above and beyond in explaining everything that goes into it along the way to help you better understand the home inspection process. They are also like a one stop shop which is so convenient, they work with other highly reputable companies for all of the other necessary services, termite, septic, sewer lateral, radon, you name it. It is so incredibility important to have a home inspection when buying a home. We are so grateful for you. Thank you again for making the home inspection process a breeze!

    We had Steve Armstrong for our inspection. Steve and his team did a great and thorough job of inspecting the home and going over details. Being first-time homebuyers, Steve answered questions we had as we went and educated us on things … More we didn’t know.
