Property Inspections
Janesville Home Inspection Services
Every home has a story. Our job is to help you understand its condition before you take ownership. A home can look great on the surface while still hiding costly concerns. That's where a thorough inspection truly matters.
Our goal is to provide you with a clear understanding of the property's condition so you can move forward with confidence.
Through fact-based inspection reporting and detailed digital inspection reports, we document the conditions we observe with photographs, measurements, video, and clear explanations when appropriate.
Our Janesville home inspections evaluate the readily accessible major systems and components of the property, including:
- Roofing and exterior components
- Basements and crawlspaces
- Plumbing systems
- Attics, insulation, and ventilation
- Interior components
- Decks, porches, and exterior structures
- Foundations and structural components
- Electrical systems
- Heating and cooling systems (HVAC)
- Windows and doors
- Garages
- Appliances and other readily accessible components
Our inspections are thorough, practical, and designed to help you understand not only what we found, but why it matters.
During the inspection, we point out and explain observed defects as well as important conditions that may not be defective.
When evaluating foundation walls, for example, we commonly use a laser and 6 foot level to document relative measurements. Those measurements are incorporated into the inspection report along with photographs and video to provide clear documentation of the foundation's condition.
We don't simply check boxes. We use detailed, fact based inspection reporting to document and explain the condition of the property you are preparing to purchase.
You can view sample inspection and environmental reports to see examples of the photographs, videos, measurements, findings, and documentation our clients receive.
Simply put, we believe the quality of our work speaks for itself, and we have been proving it every day through 25+ years of inspection experience and more than 20,000 completed inspections.

What 25+ Years of Wisconsin Inspection Experience Brings to a Janesville Home Inspection
Janesville has a diverse housing stock ranging from older homes in established neighborhoods to newer subdivisions, commercial buildings, investment properties, and rural properties surrounding the city.
After inspecting properties in the Janesville area since the early 2000s, there are many neighborhoods where we can stand on a roof and likely see other homes we have inspected over the years.
That local experience matters.
We understand the characteristics, construction methods, aging building systems, renovations, and property concerns found in homes throughout the Janesville area.
Older Janesville homes may contain aging electrical systems, older plumbing materials, foundation concerns, outdated insulation and ventilation, aging roofing or mechanical systems, and previous renovations completed under different construction standards.
Newer homes can present an entirely different set of concerns, including installation defects, drainage and grading problems, roofing deficiencies, siding installation issues, attic ventilation concerns, and workmanship defects.
No two properties are identical.
Our 25+ years of inspection experience allow us to evaluate each property based on its age, construction type, systems, modifications, and individual conditions rather than approaching every property with the same checklist.

Perspective
What We've Learned Inspecting Janesville Properties Since the Early 2000s
Long term experience in a community provides perspective that cannot be gained from a checklist alone.
During our years of inspecting Janesville homes and commercial properties, we have evaluated properties representing different eras of construction, building materials, mechanical systems, renovation practices, and levels of maintenance.
That history helps us recognize when a condition is consistent with the age and construction of a property and when an observation deserves closer attention.
We regularly evaluate:
- Older foundations and structural systems
- Plumbing materials from different construction eras
- Attic insulation and ventilation configurations
- Exterior siding and installation details
- Previous additions, renovations, and remodeling
- Aging electrical components and previous electrical modifications
- Roof coverings, flashing, drainage, and exterior systems
- Heating and cooling equipment
- Grading, drainage, and moisture-related conditions
- Newer construction and installation workmanship

Detailed Inspection Reports — Not Just a Checklist
The value of an inspection depends not only on what your inspector observes, but on how clearly those observations are documented and explained.
Tri County provides photo- and video-enhanced digital inspection reports designed to make complicated property conditions easier to understand.
