Triangle Dehumidifiers serves the greater Raleigh metro area — including Cary, Apex, Holly Springs, and Fuquay-Varina — with crawlspace humidity control systems sized and installed for each home's specific conditions.
Raleigh, NC
Raleigh's mix of older ranch homes and newer construction means a wide range of crawlspace conditions — from unprotected bare soil to partially encapsulated spaces. High summer humidity regularly pushes untreated crawlspace RH above 75%, making active dehumidification essential for most Raleigh homes with crawlspace foundations.
Learn about our installation process →Cary, NC
Many Cary neighborhoods were built in the 1980s and 1990s with vented crawlspace designs that were standard at the time. These spaces frequently show elevated moisture and early wood discoloration during humidity season. We serve homeowners throughout Cary with properly sized dehumidification systems and vapor barrier solutions.
Learn about our installation process →Apex, NC
Apex's growth has brought a variety of home construction eras and crawlspace conditions. Whether your home has a vented or encapsulated crawlspace, we assess moisture levels and recommend the appropriate system to maintain 45–50% RH through the humid months typical to the Triangle region.
Learn about our installation process →Holly Springs, NC
Holly Springs homes often sit on clay-rich soil with high moisture retention. This increases the evaporative load on crawlspace environments and makes vapor barrier installation and active dehumidification especially important. We work with Holly Springs homeowners to design complete moisture control systems for their specific soil and construction conditions.
Learn about our installation process →Fuquay-Varina, NC
Fuquay-Varina's combination of older homes and rapid new development creates varied crawlspace challenges. Newer construction may meet modern encapsulation standards, while older homes often have exposed soil, open vents, and no active humidity control. We serve both with the right solution for each specific space.

North Carolina's climate produces hot, humid summers that regularly push outdoor RH above 85% — conditions that drive crawlspace humidity to damaging levels without active control.
The Triangle region — Raleigh, Durham, Chapel Hill and surrounding communities — experiences a humid subtropical climate with long summers and mild winters. Average summer RH in the Raleigh area frequently exceeds 80% during evening hours, and untreated crawlspaces track closely with outdoor humidity levels when vents are open.
This regional climate makes crawlspace humidity control not a luxury item, but a practical necessity for most homes with crawlspace foundations. The question is not whether to address humidity — it is how to address it correctly.
