The Challenge: Restoring and preserving this magnificent historic building in Boston’s Back Bay to its original appearance.
Project Scope:
The Hooper Mansion resides in the residential Back Bay historic district with unobstructed views of the Charles River Basin and was one of the largest buildings in Boston when it was constructed in 1889.
Restoration of exterior masonry included stone/brick repair and replacement of damaged or missing elements, repointing mortar joints with historically appropriate mortars, and delicately performed masonry cleaning.
Windows were replaced with custom wood windows with insulated glass to replicate the original historic design.
Repairs to existing slate roofing and copper flashings. Replacement of all low-slope membrane roofing systems.
Removal of all membrane roofing systems, including the main roof deck, balconies and carriage house, and replacing with more durable systems.
Reconstruction of previously lost portions of the North Elevation and Carriage House facing the Charles River, including new cast stone and masonry, new flat seam copper roof, flashings, gutters, and downspouts.
