When it comes to home renovations, there’s always a lot of excitement. Whether you're planning a kitchen remodel, bathroom upgrade, or a new addition to your home, the possibilities are endless. However, before you dive into your project, it’s important to consider a crucial factor that might affect the safety of your home and your health: doing an asbestos inspection. In homes built before the 1980s, asbestos was widely used in construction materials for its heat-resistant and insulating properties. Unfortunately, disturbing materials that contain asbestos during a renovation can release harmful fibers into the air, which can be a health risk.
This is where asbestos inspection and asbestos testing come into play. If you're planning a renovation in the Denver Metro area, an asbestos inspection can help you identify any materials that may contain asbestos. In this guide, we'll walk you through the process of what to expect during an asbestos inspection, how asbestos testing works, the regulations surrounding asbestos sample collection in Colorado, and why it's crucial to take these steps before starting your home project.
Why Is an Asbestos Inspection Important for Your Renovation?
Before we dive into the specifics of the inspection and testing process, it’s important to understand why an asbestos inspection is a critical first step in your renovation journey.
What Is Asbestos?
Asbestos is a naturally occurring mineral that was used extensively in construction materials from the 1900s through the 1980s due to its resistance to heat, fire, and chemicals. It was commonly found in products like insulation, flooring materials, ceiling tiles, and even roofing materials. While asbestos itself isn’t dangerous in its intact state, if materials containing asbestos are disturbed, they can release tiny fibers into the air. These fibers, when inhaled, can cause severe health issues, including lung cancer, mesothelioma, and asbestosis.
What Are the Risks of Asbestos Exposure?
Exposure to asbestos can be dangerous, especially when fibers are inhaled over time. Because asbestos-related diseases often take decades to develop, the risks may not be immediately visible. Homeowners and contractors who perform renovations without an asbestos inspection may unknowingly expose themselves and others to these harmful fibers. By scheduling an asbestos inspection, you can avoid the risks associated with asbestos exposure by ensuring that any potential ACMs (asbestos-containing materials) are identified and managed safely.
When Should You Schedule an Asbestos Inspection?
If your home was built before the 1980s, it’s a good idea to schedule an asbestos inspection before starting any renovation or demolition project. While some materials may be obvious, others—like certain wallboards, joint compounds, and flooring tiles—might be more difficult to identify without testing.
If you are planning a kitchen remodel, bathroom remodel, or any project that involves disturbing walls, floors, ceilings, or pipes, it’s essential to conduct an asbestos inspection beforehand.

The Asbestos Inspection Process: What to Expect
An asbestos inspection typically involves two main components: a visual inspection and asbestos testing. Here's a detailed look at each step of the process:
1. Visual Inspection
The first step in an asbestos inspection is a visual examination of the areas that are being renovated or potentially disturbed. A certified asbestos inspector will walk through your home to identify any areas where asbestos-containing materials may be present and may be impacted by the renovation. This visual assessment includes looking for suspect material such as floor tiles, drywall, or ceiling textures that may contain asbestos.
During the visual inspection, the inspector will focus on the following areas of your home:
Floors and Floor Tiles: In older homes, floor tiles, adhesives, and underlayment may contain asbestos. This is especially true for vinyl and linoleum tiles installed before the 1980s.
Walls and Ceiling Materials: Textured walls and ceiling materials, such as popcorn ceilings, were often mixed with asbestos for added durability.
Insulation: Insulation around pipes, ducts, and boilers is another common area where asbestos was used. The inspector will check for any signs of asbestos-containing materials in these areas.
Walls and Roofing: Drywall, joint compound, and certain roofing materials may also contain asbestos, especially in homes built before the 1980s.
After the visual inspection, the inspector will determine which materials should be tested for asbestos and explain the next steps in the process.
2. Asbestos Testing (Sampling)
If the inspector suspects that any materials may contain asbestos will be impacted by the renovation, they will collect samples for testing. This is where the actual asbestos testing process comes into play. The inspector will carefully collect small samples of the materials that are suspected to contain asbestos and send them to a certified laboratory for analysis.
It’s important to understand that asbestos testing is essential to confirm whether or not a material actually contains asbestos. A visual inspection alone cannot definitively identify the presence of asbestos; laboratory testing is required to confirm it.
3. Laboratory Analysis and Results
Once the samples have been collected, they are sent to a certified laboratory where they are analyzed for the presence of asbestos fibers. The laboratory will examine the samples under a microscope to determine whether asbestos is present and, if so, how much asbestos is contained in the material.
Positive Result: If asbestos is found in the sample, the inspector will provide you with a detailed report, including the type and percentage of asbestos present. The inspector will also provide recommendations on how to manage or remove the asbestos-containing materials.
Negative Result: If no asbestos is found in the sample, the inspector will still provide you with a detailed report and you can proceed with your renovation project safely, knowing that no hazardous materials are present in the tested areas.
What Happens if Asbestos Is Found?
If the test results come back positive for asbestos, you’ll need to make a plan for how to manage the asbestos-containing materials. In some cases, asbestos removal may be necessary, especially if the materials are deteriorating or will be disturbed during the renovation process.
However, in some cases, if the asbestos-containing material is in good condition and won't be disturbed, the inspector may recommend simply encapsulating the material (covering it with a protective layer) to prevent exposure.

How Many Asbestos Samples Are Required in Colorado?
One of the most common questions homeowners have when preparing for an asbestos inspection is, “How many samples will be collected?” The number of samples required depends on the materials being tested and the area being inspected. In Colorado, the Colorado Department of Public Health and Environment (CDPHE) has clear guidelines for sample collection during an asbestos inspection.
Guidelines for Sample Collection
In our blog post, How Many Asbestos Samples Are Required in Colorado? A Simple Guide, we explain that the CDPHE recommends collecting a specific amount of samples based on the type of material being disturbed when assessing the likelihood of asbestos. For example:
Kitchen Remodel: If you’re remodeling your kitchen, the inspector might collect samples from your drywall and joint compound (total of five samples between the two type of material), flooring (at least two samples per flooring type), and backsplash adhesive (two samples). For most, the average number of samples needed for a kitchen remodel is between 7-9 samples total.
Bathroom Remodel: In a bathroom, the inspector would likely collect samples from drywall and joint compound (at least three samples per textured surface and 2 joint compound), flooring (at least two samples per flooring type), shower/tub tile adhesive (two samples). Similar to a kitchen remodel, most bathroom remodels require at least 7-9 samples.
For larger areas or more complex renovation projects, additional samples may be required to ensure that all potential ACMs are properly identified.
If there are different types of material, then this could also change the number of samples. When in doubt, ask your inspector on-site for the final number of samples needed.
How the Sampling Works
For each material suspected to contain asbestos, the inspector will collect a small sample (typically a few square inches) to send for testing. The number of samples collected will depend on the size of the area and the number of different materials in question.
