The Problem
Warning signs
- Musty odors inside the living space, condensation on HVAC ducts in the crawlspace, buckled hardwood floors, or visible mold on floor joists.
Our Diagnosis
Lack of adequate mechanical dehumidification and insufficient natural ventilation to exchange moist air.
Root cause
Environmental moisture entering through foundation walls and floor, combined with inadequate airflow in the Dallas, TX climate.
How We Fixed It
- 1
Site preparation and assessment for dehumidifier placement. 2. Cut and frame two new foundation vent openings. 3. Install and flash standard foundation vents to ensure weatherproofing. 4. Run a dedicated electrical circuit to the crawlspace for the unit. 5. Install the AprilAire dehumidifier unit and route a condensate drain line to a proper discharge point.
How to Prevent This
- Ensure the condensate line remains clear of debris and check the dehumidifier filter every 6 to 12 months. Monitor humidity levels to ensure they stay below 55%.
