Before + after · Orlando family home
Teen son's headaches resolved in six weeks.
A 3-bedroom Orlando home with a teenage son who stopped sleeping well six months after moving in, resulting in headaches, brain fog, and poor sleep. Trips to two doctors yielded no answers, then a functional medicine practitioner referred them to Kit.
Problem
Couldn't focus on homework
Son’s headaches and sleep loss started six months post-move. No one else in the house was reporting noticeable symptoms.
Found
Two issues, one inspection
Wi-Fi router was located on a shelf above the bed in the son’s room. Moisture detected behind the primary bathroom vanity, hidden from visual inspection.
Fix
Mitigation strategy
Router relocated to the living room on a timer. Supply line replaced, cabinet dried and sealed. Exhaust fan added to the bathroom.
Result
Symptoms resolved
Headaches gone within three weeks. Sleep back to baseline at six. Family still runs the router timer as standard practice.
What clients say
Calm, careful, careful again.

Remodeling ugly houses led to a career pivot.
My passion for remodeling the ugliest houses I could find came with an unexpected cost. My family’s health suffered from hidden mold, EMFs, and other toxins in the homes we lived in while I worked on them. For decades, we spent tens of thousands on healthcare solutions that never resolved.
The truth came into focus later. The internal environment (our health) had been shaped by the external environment (the homes). That discovery pushed me into Building Biology. Today I run whole-home assessments across Florida and Georgia, with virtual consults anywhere in the US. I do travel to other areas on request, please request more information if you are interested.

Five ways 5G is changing what a safe bedroom looks like
5G is not a cellular upgrade. It is a frequency profile change with implications for every bedroom inside 100 meters of a small-cell antenna.
Foundations
Dirty electricity · the EMF source nobody tests for
Dimmer switches, LED drivers, solar inverters, modern electronics · they all pollute the wiring in your home with high-frequency transients. Almost no inspector measures it.

What is Building Biology?
A Building Biology assessment treats the home as a whole system, pulling in moisture, ventilation, materials, EMF, and air quality together. The training follows 25 principles through the Building Biology Institute. Standard mold inspections often stop at visible checks; a Building Biology assessment goes further by asking why the problems are happening in this particular home.
How long does an inspection take?
2-8 hours on site, depending on the size and complexity of the property. An average single-family home runs about four hours. Larger homes with crawlspaces, finished attics, or a renovation history can run longer. The exterior assessment happens first, then interior room by room. Kit walks you through key findings before leaving.
Do you serve my area?
In-person inspections across Florida and Georgia. Virtual Consults across the entire US and Canada. If you’re outside FL or GA and want more than a consult, reach out. Kit travels for larger engagements when scope and timing align.
Do you sell remediation services?
No. Holistic Home Zone is an assessment-only practice. The report is independent. You can hand the IICRC remediation protocol to any qualified remediator. Kit can share names of qualified independent contractors in your area if you ask.
What do I get in the report?
A written report with photos, readings, measurements, and air sampling results when taken. Findings sorted by status: within range, elevated, action required. An IICRC remediation protocol if one is needed. Recommendations prioritized by impact. Plus a 30-minute consult after you receive the report.
How should I prepare?
See the preparing-for-inspection guide. The basics: let the air settle (turn off purifiers, keep windows closed for a day), access to closets and utility spaces, and avoid candles or diffusers that mask odor cues.
Ready when you are.
Book an inspection, schedule a virtual consult, or request more information. Deb handles the scheduling so there’s a human at the other end of the phone.
