Only 5 miles from Downtown LA; playing the long game combined with the outlook and the halo effect from Downtown LA will penetrate South LA.

Duplex was completely remodeled but one of the walls started to have some "moisture patches"It is only a portion of 1 wall and only in the downstairs unit.

There are multiple ways to handle moisture from exterior preventative systems to interior French drains.

June 26 I moved my vacuum, and the whole wall had fallen in due to moisture standing water under the crawlspace  which obviously this explains the smell because it was standing water from the time I started living there all the way up to the time that he started fixing, it which was around the middle of July.

Due to the lack of moisture, our selection criteria, and construction materials, our average annual maintenance is about $350.Growing - There is over $22B under construction and more announced, which will create thousands of new well-paying jobs.

When all was said and done, our $12k got us:New windows throughoutInterior and exterior painting for the house and exterior painting on the garageA small amount of roofing - The house's roof was only a year old, but the cover for the back porch never got redone for some reasonGutter guards along the whole houseNew floors throughoutNew kitchen appliancesNew bathtub enclosure (including moisture-resistant drywall)Some light electrical work (new lights, flipping out receptacles, etc) What was the outcome?

Once the walls are 'broken down' a slew of issues (i.e. plumbings & electric issues, moisture, structural damage, etc) can arise that will affect the estimate.I would use $175/sq. ft. to calculate your estimates.

If there is moisture, we simply put in a sump pump/ dehumidify and the glass block window with the vent.

Cracks in joints at blocks and moisture in crawl. 

Hello,How would you all handle repairs to foundation and remediation of moisture issues in crawlspace when shared with an adjoining quadplex?
