Mr. J. Bronchos saw my DIY Advisor blog and he called my PennySaver USA advertisement. He had some deteriorating garage floor vents that needed to be cleaned up. The wall had been eaten by rodents and he wanted to clean up his garage. Joe lives in Eastvale California. According to the city of Eastvale, the city was incorporated on October 1, 2010 and has an ever-growing population of over 55,602 residents.

This post show the five steps of the repairing garage weep vents.
