About Windowsills Work

A major part of our core business is repairing, replacing and restoring window sills, lintels and copings. Sills are crucial parts of your house since they shed water that runs down toward the windows directly to the ground, preventing it from going down the wall onto the brickwork. Since these window sills are high saturation areas, it’s important to have them well sealed and constructed with the proper materials with as few joints as possible.

We use several products on window sills. Arriscraft sills are impermeable man-made stone slabs with a pre-cut drip edge, and are available in various thicknesses that can accommodate a variety of window sizes. Indiana limestone, a popular and very long-lasting material, comes in lengths of up to 10 feet long, so a single piece can create a sill on almost any window. We also install custom-formed silica concrete window sills, with a variety of other finishes to match original sills on the house.

Arches and lintels are structural supports above a window, doorway or opening. Over time they can crack or shift, destabilizing the wall above, so special skills are required to repair or replace them. We always install a metal angle iron to support the opening properly, and have a variety of options like brick, stone, and Arriscraft for arches and lintels.

Our services include:

May 2024, I had Stonehenge Masonry replace two bricked window sills that had broken, cracked and split bricks with Indiana limestone sills. These came in 8 foot lenghts that were cut to fit in perfectly. My experience with this company's workers that I dealt with from start to finish were A+. They were professional, courteous, explained the work to be done and left a clean work site when they were done. Neighbours even expressed how nice the front of the house now looked.
