Job completed for How We Fixed Porch-Driven Rot with Structural Reinforcement and Moisture Control

Completion date: June 9, 2025

Location: Scottsboro, AL

Why did the customer contact us?

A homeowner contacted us after noticing signs of structural damage beneath the home near an open porch area. He explained that the porch had been left open to the elements, and over time rainwater and humid air were able to blow directly into the crawlspace, keeping that section damp far too often. He’d started to see warning signs like soft, deteriorating wood, uneven support points, and a persistent musty smell, and he was worried the moisture exposure had begun to compromise the framing. We scheduled an on-site evaluation to assess the extent of the damage, identify how the open porch was feeding water and humidity into the crawlspace, and develop a plan to stabilize the structure and stop the moisture from continuing to cause decay.

Solutions provided:

After our evaluation confirmed the open-porch exposure was allowing outside moisture to drive rot and weakening key framing components, we fixed both the cause and the structural damage it created. We started by treating affected areas with a Pro Cleaner hydrogen peroxide application to address microbial growth and help sanitize the crawlspace. To stabilize and reinforce the floor system, we installed PowerPost floor supports, doubled/scabbed compromised floor joists where reinforcement was needed, and added a steel beam to restore strength and proper load support. With the structure secured, we focused on long-term moisture control by blocking the foundation vents and installing a durable 9 mil vapor barrier to cut off ground vapor. We then added a Sierra Watchdog NXT 85-pint dehumidifier to keep humidity in a safe range year-round, and finished with a custom-built PVC crawlspace door to create a tighter, more durable seal—helping prevent future moisture intrusion and protecting the repaired structure.
