    Case Study: Brick-to-Stone Window Sill Replacement

 
        Before and After

   

 
    The Assignment:
        The brick window sill was damaged, needed replacement.
        A rocked-face limestone sill was desired.

    The Underlying Problem:
        The masonry and bricks on the top row had cracks letting water in.
        Sills made of bricks are inherently weak, and should be stone.

 
The Problem: A Sill made of Brick
Clearly, there are broken bricks.
With a canvas dropsheet to protect the roof,
we chiseled away the brick sill.

 
The Internal Damage: None.
Fortunately there was no rotted wood behind the bricks.
We then cut the sills to fit the opening perfectly, evenly.

 
Cement Base for Sill
We set a base of cement for spacing and the angle we wanted.

 
Dry Fitting the Stone Sills
After cutting we fit the stones in place.

Alignment
From multiple angles we check the alignment of the stones.

Sealant closes the Gaps
Sealant allows the sill to have some flexibility to expand and contract, and prevents water from entering.
Standing Back, Two Sills.
The stone sill, with a rocked or chiselled face, looks nice.
