Wood Repair and Window Restoration



My crew is putting the finishing touches on our window work at the Fogg Library in Weymouth. I figured this would be a good time to reflect on what we have done in the short amount of time we have been on site and discuss a bit about what I've learned.

For this job, my crew has concentrated on repairing the rot and insect damage on the window sills and frames throughout the building. A secondary crew has been working on repairing any damaged window sash including fixing joinery and repairing and reglazing any broken or damaged glass.

The frame and sill repair starts with assessing the existing wood and removing any rotted or damaged sections. Specialized wood consolidant is applied to strengthen the fibers of the areas to be repaired before epoxy is added to fill any voids. In areas with severe rot and decay, new wood is spliced in and shaped to conform with the existing material.

After we received the restored window sash, our work turned to fitting and installing window weights, pulleys, and cords. Finally, the window sash were returned to their openings and adjustments were made to ensure smooth operation of both upper and lower sash. Lastly, the original locking hardware and decorative pulls were reinstalled.

There is still a lot of work to be done on the building but at least the unsightly plywood window covers that have adorned the historic structure for several years have been replaced by the carefully restored original windows. For the public that drives by the Fogg Library every day, our work represents a small but significant evolution of the project. Some pictures of my work can be seen below.

Watch out Kai! Kai was glazing a window on the East elevation before his 2 wheel drive manlift got stuck. I bailed him put by putting a shim under the slipping wheel.
