Mold Inspections The Name You Know and Trust

Fort Collins Mold Inspection Services

You Saw Something. Now You Need to Know What It Is.

A discolored patch near the baseboard. A musty smell in the basement that wasn't there last fall. A spot behind the bathroom vanity that doesn't look like water staining. You don't know if it's mold, what kind, or how far it goes.

That uncertainty is exactly what a mold inspection is for. At Allen Service, our licensed technicians assess your home, identify what's present, determine how far the growth has spread, and give you clear answers about what comes next. You leave the inspection knowing what you're dealing with, not still guessing.

Contact us at (970) 431-6574 to schedule a mold inspection in Fort Collins or across the Front Range. We are available seven days a week.

What a Professional Mold Inspection Covers

A professional mold inspection is different from looking around and noting visible discoloration. Our technicians assess areas beyond the visible surface, because mold growth in Colorado homes frequently originates in wall cavities, behind drywall, under flooring, and in attic and crawl space spaces where it isn't visible until it's become a larger problem.

During an inspection, our team evaluates:

Visible mold growth on surfaces – We document the location, approximate coverage, and visual characteristics of any surface mold. The inspection records this in a way that supports whatever next steps are appropriate, including remediation, insurance documentation, or a pre-sale disclosure.
Hidden mold growth behind walls and under flooring – Moisture that reaches wall cavities and subfloor materials creates conditions for growth that isn't visible from the surface. We use moisture detection equipment to identify elevated readings in areas where mold growth may be present but not yet visible.
HVAC systems and ductwork – Mold in ductwork spreads spores through the home every time the system runs. We assess HVAC components and ductwork as part of the inspection because air circulation is one of the primary ways mold spreads beyond its original location.
Attic and crawl space conditions – Colorado homes accumulate moisture in attics and crawl spaces, particularly in properties along the Front Range where humidity swings are common. These areas are frequent mold sites that go undetected until the growth is significant.
Moisture sources contributing to growth conditions – Removing visible mold without identifying the moisture source that caused it leads to recurrence. We identify plumbing leaks, condensation issues, ventilation gaps, and other moisture sources as part of every inspection.

After the inspection, we walk through our findings with you in plain language: what we found, where we found it, what's likely causing it, and what your options are for addressing it.

When Should You Schedule a Mold Inspection?

Some situations call for an inspection clearly. Others are less obvious. We get calls from homeowners who waited too long because they weren't sure whether what they noticed was worth calling about. Usually, it was.

Conditions that warrant a professional assessment include:

Visible discoloration that keeps coming back after cleaning – Mold that returns after surface cleaning has an active moisture source feeding it. Surface treatment alone won't resolve a recurring growth problem.
A persistent musty odor without a clear source – Mold has a distinct smell, and it doesn't require visible growth to produce it. A musty odor that doesn't go away with ventilation often means growth is present somewhere out of sight.
Any area with recent or ongoing water damage – Water damage creates mold-favorable conditions within 24 to 48 hours. Homes that experienced flooding, plumbing leaks, or roof damage should be inspected before the work is closed up, not after.
Before purchasing or listing a property – Mold discovered during a home sale creates delays and negotiation pressure. An inspection before listing or before closing gives you accurate information and time to address anything that's found.
Unexplained respiratory or allergy symptoms in residents – Elevated mold spore counts can contribute to respiratory symptoms, particularly in residents with allergies or sensitivities. If the symptoms correlate with time spent at home, an inspection is worth scheduling.

If you're not sure whether your situation warrants an inspection, call us. We'll ask a few questions and help you determine whether an assessment makes sense.

Colorado Homes and Mold: What Makes the Front Range Different

Fort Collins, Denver, and the surrounding Front Range communities sit at elevation with a climate that swings from dry to humid across seasons and even across a single week. That variability creates specific mold risk patterns in Colorado homes that don't apply the same way in other regions.

Basements and crawl spaces in older Fort Collins homes, many of which were built before modern moisture barriers were standard, accumulate ground moisture during snowmelt and spring rain. Properties in lower-lying areas near the Poudre River corridor see higher humidity levels that accelerate growth in wall cavities and subfloor framing. Attic mold is common in homes where inadequate ventilation traps warm, moist air during heating season.

Our technicians have assessed mold conditions in homes across this region for years. The local knowledge matters when you're trying to understand where to look and what's actually causing what you're finding.

What Happens After the Inspection?

The inspection gives you information. What you do with that information is your decision.

If the inspection finds mold that warrants remediation, we explain the scope of what we found, the approach we'd use to address it, and what you can expect from the process. We don't assume you'll hire us for the remediation, and we don't pressure you toward any particular decision. The inspection report is yours regardless of what you choose next.

We also offer mold removal services for properties where remediation is the appropriate next step. Having the same team handle inspection and removal means nothing is lost between the assessment and the work.

Frequently Asked Questions About Mold Inspection

The following are the questions homeowners most often ask before scheduling an inspection.

How Long Does a Mold Inspection Take?

For most residential properties, an inspection takes between one and three hours. Larger homes, properties with extensive crawl spaces or multiple HVAC zones, or homes with widespread visible growth may take longer. We give you a time estimate when you schedule.

Do I Need to Leave My Home During the Inspection?

No. You don't need to vacate your home during an inspection. Our technicians move through the property with their equipment without disrupting your household.

Will the Inspection Tell Me What Type of Mold I Have?

A visual inspection and moisture assessment identifies growth, documents its location and extent, and assesses the conditions contributing to it. If you need laboratory identification of the mold species present, we can discuss sampling as part of the inspection process. Our technicians explain what sampling adds and whether it's relevant to your situation.

Is Mold Always Visible During an Inspection?

Not always. That's why the inspection includes moisture readings and assessment of concealed areas. Our technicians look beyond the surface for elevated moisture that indicates hidden growth. In some cases, opening a wall or floor section is necessary to get an accurate picture of the extent of growth.
