Carriage House Sill Replacement & Repairs
The sills of the carriage house had rotted from the outside and collapsed, resulting in structural problems.

Rear Sill: Before Restoration Work
    

As shown in the photos the entire rear sill of the carriage house has collapsed on the outside, and has caused
the rear of the carriage house to sag by several inches.  Past attempts at bracing the wall have failed to
fix the problem.  The wall was jacked up and braced, the old sill removed, and a new sill installed, as
well as additional repairs.

A New foundation of reinforced concrete was poured and anchor bolts installed to hold the new sill in place and
tie the sill into the rest of the structure.
           

Completed Restoration of Rear Sill
Additional work included replacement of jack studs, reinforcement of support beams with metal brackets and additional
structural work.  The new sill consists of a foundation composed of reinforced concrete, pressure treated lumber,
top plate.  The original sill was 6" of oak.  Lally columns were added at load points for additional strength.


    

Right Sill: Before Restoration Work


A previous attempt at sill replacement and foundation repairs by a contractor who was both not licensed and
lacked experience with structural restoration work  resulted in cracked floor joists, and the entire ride side of the 
carriage house "jacking" or being pushed out of alignment.

Restoration Work On Right Sill
    
A majority of the floor joists were cracked as a result of the previous failed restoration work, and were replaced.
