Serving Louisville and Southern Indiana
Clean, Healthy Air
We control moisture and humidity to improve indoor air quality and reduce mold, allergens, and odors.
Lower humidity • Healthier indoor air
Water Managed at the Source
From vapor barriers to drainage solutions, we stop water intrusion before it leads to rot, mold, or foundation damage.
Encapsulation • Drainage • Moisture control
A Clear, Proven Process — From Inspection to Certification
We follow a structured approach to assess, protect, and document the conditions beneath your home — so nothing is left to guesswork.
Step 1 — Inspect
We inspect moisture levels, air quality indicators, structural components, and existing conditions to establish a clear baseline.
Step 2 — Protect
Based on what we find, we implement the right solutions — from encapsulation and moisture control to structural reinforcement.
Step 3 — Verify
We verify results through follow-up inspections and optional monitoring, ensuring the crawl space remains dry, healthy, and stable.
Why It Matters
in Numbers
Facts & Figures
50%
of the air you breathe
In many homes, up to half of the air on the first floor originates from the crawl space through stack effect.
70%
relative humidity
High crawl space humidity creates ideal conditions for mold growth, wood decay, and pest activity.
Years
of hidden damage
Moisture-related rot and settlement often develop slowly — long before visible signs appear upstairs.
caught early vs. late
Early detection and control can prevent costly repairs and protect long-term home value.

WHY CRAWL SPACE GUARD
Protect the Invisible, Secure what matters Most
Most homeowners never see what’s happening beneath their home — until something goes wrong.
Crawl Space Guard was built to change that.
We focus on the systems below your living space that quietly affect air quality, moisture, energy efficiency, and structural integrity. By combining building science, monitoring technology, and practical construction experience, we help homeowners prevent problems — not just react to them.
It’s not about scare tactics.
It’s about clarity, protection, and long-term peace of mind.
What Our Customers Say
Our old house is like brand-new again, ready for the next 150 years. Completely changed the feel of everything - level and flat floors and no more smell!
Scott H.
You've renewed our home and made us proud owners... You delivered far more than promised or that we expected in restoring our 140-year-old home.

I contracted with Tyler... I can't imagine going through this process with anyone else. He was my "rock" and my voice of reason all the way. I truly felt like the smallest of things was as important to him as it was to me. His attention to detail, making himself available and his ongoing communication really made a difference. His experience and skill was reflected throughout the project. No doubt he will do an excellent job if you're looking for someone to help with your project.
Alyce R.
Tyler was fair and prompt. During the inspection and planning process I didn’t feel overwhelmed with information as he concisely laid out what needed to be done and how he would do it. His background in engineering really was apparent. Our old home is now all the more sustainable for many years to come thanks to his service.

Tyler was just the person you need. The thoughtfulness and the work ethic is what you don't see anymore, and Tyler Poteet provided above and beyond. Give Tyler a shout, and trust me, you won't be disappointed. Thanks so much Tyler.
