Repairing Rotten Sill Plate and Rim Joist

Repairing Rotten Sill Plate and Rim Joist

We are a Landscape Construction Company.   Like many of our professional peers, we regard the landscape as a fundamental component of a home.  Unlike many of our professional landscape construction peers, our skill set includes a dozen years in licensed home remodel carpentry.  In the occasions where we find rot, we have the knowledge and experience necessary to not only repair the damage, but to identify the cause and remediate the defect.  Here’s a pictorial essay of a recent situation where we’ve fixed a problem that would have become an epidemic if ignored.

Rotten framing under not-so-bad looking siding

We discovered rot in an area where soil had been piled against the siding from over the years.

 

 

 

 

 

 

cut away rot

cutting away the rot

We cut away the rotten wood which consisted of a portion of the sill plate and a portion of the rim Joist.  The siding itself was surprisingly intact.  Cedar is stalwart as siding.

We replaced the rotten wood with pressure treated lumber and bronze coated screws.

Over the new framing lumber we installed Fortiflash brand butyl flashing membrane, and over that, James Hardie brand cement board siding attached with stainless steel nails.  Although no soil will be in contact with it, we will back fill with gravel bedding.  A patio will be flush to the siding in this area.

To address some of the reason this area was rotting, we core drilled a 4″ hole in the concrete retaining wall…..

and ran a titeline pipe to redirect the rainwater from the downspout that had been creating a puddle in that corner of the house.

Fixed!

    I have this same problem on one corner of my house due to termite damage. Were you able to replace that corner piece without needing to support the bearing there since it was a small corner piece? Mine is the same way, a couple of short runs under windows that I can work with….

      Hi Jeff, Thanks for your question. Yes, we didn’t need to support any of the houses weight. We cut the rotten sill out and forced a new pressure treated section in with a pry bar and an 8 pound hammer.

      Good luck with your project!
