Do you notice musty odors after it rains?

How about condensation on your windows, or allergy-like symptoms that go away when you leave home? The air inside your house is affected by what’s happening below your floors. At Air Quality by Cut ‘N Dry Waterproofing, we check crawlspaces and basements, measure key factors like moisture, particulates, and ventilation, and explain everything in simple terms. After that, we address the source with solutions like drainage, encapsulation, dehumidification, and ventilation improvements. When needed, we can also add CIMR whole-home treatment for the spaces you live in. We measure, fix, and then verify the results.

Why Air Quality Matters

It’s a whole home issue.

Air is always moving. Your indoor air quality depends on what happens below and around your home. Things like pressure, moisture, and ventilation connect your crawlspace or basement to your living spaces. If that balance is off, pollutants can travel upstairs and stick around.

Stack effect: Warm air rises and pulls replacement air from below grade. If your crawlspace or basement is musty, those odors and airborne particles ride that current into living areas.
Moisture → microbes: Persistent dampness fuels mold growth and musty odors.
Tight homes trap more: Energy-efficient, well-sealed homes can hold onto pollutants longer without controlled ventilation or treatment.

Is Your Air Telling You Something?

Little signs can add up over time. If you notice any of the issues below, especially after it rains or when your windows stay closed, your indoor air quality may be affected by moisture or problems below your home. If two or more of these sound familiar, it’s a good idea to have things checked out.

Musty smells (especially after rain)
Condensation on windows or ducts
Allergy-like symptoms at home that improve when you’re away
Visible spotting on wood/drywall or that “earthy” crawlspace odor
Headaches or stuffy noses that improve away from home

What We Check and Why

We begin by looking at the main causes, such as moisture and air movement, and then connect these sources to the symptoms you have noticed. During a typical visit, we will:

Track moisture pathways: seepage lines, elevated relative humidity, unsealed soil, rim-joist gaps, wet/compacted insulation.
Inspect likely growth zones: crawlspace framing, rim joists, cold corners in baths/laundry, and behind finishes along exterior walls.
Verify air movement & ventilation: bath/kitchen fans (vented outside vs. attic), leaky returns/ductwork, make-up air paths, dryer venting.
Note comfort patterns: when/where odors or symptoms appear (after rain, showers, laundry, or cooking), and which rooms are affected.

If testing could impact our approach or if you require documentation for real estate or medical reasons, we’ll collect specific air (IAQ) and/or surface samples. Otherwise, we won’t push tests you don’t need.

Our Approach

Inspect -> Test -> Solve

We keep it simple: find the source, test only when it helps, then fix what’s causing the problem.

Inspect

We trace the sources of moisture and air (crawlspace/basement, bathrooms/laundry, and duct returns), identify likely growth zones, and review ventilation systems to determine the root cause of the issue. You’ll get plain English findings and clear priorities.

Test Only When It Helps

We add targeted air or surface samples if the scope is unclear, hidden growth is suspected, or you require documentation (e.g., real estate, medical). Otherwise, we won’t push tests you don’t need.

Solve (Fix the Cause, Then Support the Air)

Stop moisture at the source. Depending on what we find, this may include exterior and interior drainage upgrades, tying water to a reliable pump, or sealing below-grade spaces. In practice, that often means Crawlspace & Basement Drainage Systems, right-sized Sump Pumps, targeted Foundation Waterproofing, and sealed Crawlspace Repair & Encapsulation. We recommend only what your home actually needs.
Move and clean the air. We vent baths and kitchens to the outside (not the attic), seal leaky returns, and help you choose appropriate filtration so particles don’t recirculate.
Treat the whole home (optional, recommended). After source control, add Air Quality Solutions (CIMR), which provides continuous, in-place reduction of airborne contaminants in occupied spaces.

We don’t use scare tactics. Instead, we offer a clear plan and real solutions that improve the air you breathe.

What Our Clients Are Saying

See what Michigan families have to say about the changes they’ve noticed after we solved their moisture problems and improved their indoor air quality.

Though not one to often write reviews I have to commend the Crawlspace Remediation LLC team. The work performed, workers attitude, professionalism, quality of work, communication and cooperation was great through the entire process ! The team showed up everyday and was conscientious in their work. A special shout out to Jalen, Tristan, Christian, Patrick and Joe for all their great efforts. The office support of Brianna and Brittany is also appreciated for their great communication. Lastly, Sam, the owner was exceptional to deal with. We spoke on the phone and Sam met with me personally to understand my expectations and show me how Crawl space Remediation LLC would meet my expectations. Very happy I chose a local business and I am 100% confident I made the correct choice receiving a competitive price and thorough job vs. the larger national service providers. My home feels better just days after the work was completed with improved humidity and air quality. I recommend crawlspace encapsulation and having and the work performed by Crawlspace Remediation LLC. Brian L.

It was a pleasuring working with this company to find the best solutions for our crawlspace problems. They replaced a water damaged beam, replaced bad duct work, installed a sump pump and took care to explain the process as they went along. The house is staying warmer now. Brendan was in charge of the project and was super communicative. Ty and Tristan worked with him. They were both very friendly and helpful. Brianna and Brittany in the office were both super helpful with scheduling and answering any questions I had. I will for sure use them again in the future if we have any issues with our crawlspace again. Hopefully there won't be since they did an amazing job :).

I had a lot of work done in my 18" crawlspace over the summer and I'm happy with the results. New insulation/encapsulation, sump pump, some duct repairs, jacking up the main beam of the house which had sunk over time, new crawlspace access doors. I went with the 90 mil vapor barrier material and it was well worth it. Friendly folks and they were always nice to work with. Shout out to Johnny for being so friendly and kind. Also Brianna, Meriann, Nick, and a few others whose names escape me.

Note: Some reviews mention our former names, Crawlspace Remediation and Radon Control Services. Both are now part of the Cut ’N Dry Waterproofing family of services.

Frequently Asked Questions

Michigan homeowners ask us these radon mitigation questions every day. Here are some answers to those questions about noise, post-mitigation testing, and more.

Do I need air testing, or can we just add a dehumidifier?

Begin with an inspection. If testing will impact the plan or you require documentation, we’ll conduct targeted sampling. A dehumidifier helps significantly, but it won’t resolve seepage or leaks. For those issues, drainage or encapsulation is needed.

What is CIMR, and is it safe for homes?

CIMR stands for Continuous Infectious Microbial Reduction, which is a whole-home treatment that continuously reduces airborne mold spores and microbes to low, controlled levels. We install it after moisture is under control and any needed remediation is complete. It’s designed for use in occupied spaces and sized to your home.

Does CIMR replace mold remediation?

No. Visible growth and contaminated materials must be removed (per best practices), and the moisture source fixed. CIMR is the “finishing step” to keep airborne counts lower afterward.

How soon will musty odors improve?

Musty odors often improve quickly once moisture is reduced, sometimes within days. After remediation and dehumidification, and if you choose CIMR, most homes notice steady improvement over the next one to two weeks as materials dry.

Do I need to leave the house while the work is being done?

Inspections, dehumidifier installs, and CIMR installs usually don’t require you to leave. During mold remediation, we isolate the work area with containment; you can typically remain home while avoiding that zone. We’ll let you know if any short exclusions are needed.

What's the stack effect, and why does it matter?

Warm air rises and pulls replacement air from below grade. If crawlspace/basement air is damp or musty, those odors and particles can ride that current into the living areas of your home. Fixing moisture issues below often improves the air quality above.

Will HVAC tweaks help improve indoor air quality?

Usually. Common fixes include sealing leaky returns, using an appropriately rated filter, and ensuring bath and kitchen fans vent outdoors, not into the attic.

How much ongoing maintenance is there?

Dehumidifiers: keep drains clear, clean/replace filters, verify the setpoint, typically maintaining a relative humidity of around 45–50%.

CIMR: Replace the active cell/module according to model guidance.

Encapsulation/drainage: quick seasonal check for damage or debris. We’ll outline a simple maintenance plan.

How does radon fit into indoor air quality?

Radon is a radioactive gas that rises from the ground. If your test reveals high radon levels, address radon mitigation first. After that, you can consider indoor air quality steps like dehumidification and CIMR.

What will this cost?

It depends on what your home needs. We tailor solutions for your home’s unique needs (not one-size-fits-all) and give a clear, no-pressure estimate. Financing is available.
