The new weld plate erection bars were painted with a zinc-rich coating before being welded into place. This type of coating prevents rust and corrosion without the need for hot-dip galvanizing.

Because we welded the plates on-site, ESI was issued a fire-safety permit through the Newton Fire Department. Thank you to the Department for providing us with firefighters to perform detail duty!

348 Beacon Street Tue, 29 Mar 2016 16:29:15 +0000 READ MORE]]> 348 beacon

348 Beacon Street is a condominium complex located in the Back Bay area of Boston that runs adjacent to Storrow Drive, overlooking the Charles River. ESI concentrated on repairing four chimneys where the masonry began to fail. The EPDM roof membrane had been pulled away from the termination bar due to age and shrinkage of the roof membrane. In addition, we restored the buildings authenticity. ESI had to complete the following tasks.

  • Repoint all masonry mortar joints on the chimneys and façade to create a water tight masonry wall.
  • Remove the area of EMPDM roofing membrane and install a new piece of membrane, properly seal the roof and terminate all edges of the membrane to eliminate water penetration.
  • Remove and replace window and door perimeter sealants to prevent leaks.
  • Scrape, prime, and apply two coats of latex paint to the historic brick molding to waterproof the window perimeter.
  • Clean the front façade as per Back Bay Architectural Commission Guidelines.

Masonry Repairs at The Anchorage Apartments in Charlestown, MA Mon, 22 Feb 2016 19:39:29 +0000 READ MORE]]> anchorage apartments in Charlestown, MA
The Anchorage Apartments is a historic building located in the Charlestown Naval Yard, Charlestown, MA. The Anchorage is situated on the waterfront and is exposed to the harsh New England coastal weather. Over time, the salt water erodes the masonry mortar joints and as the seasons change, the thermal expansion and contraction of water within the old joints could cause spalls and cracks. ESI took the time to restore the natural splendor of this historic naval building. The concentration of work included:

  • Cut and point all masonry mortar joints.
  • Apply a clear waterproof sealer on all masonry.
  • Caulk and seal all windows to maintain a water tight seal in order to eliminate water infiltration and moisture damage.
  • Rebuild ten masonry columns to match the existing brick
  • Patch limestone headers and sills.

Waterproofing Your Masonry or Brick Before Winter Tue, 20 Oct 2015 21:15:51 +0000 READ MORE]]> water-beads-on-red-brick2-300x196Winter is coming! As the weather gets colder in Boston, we want to remind building owners and home owners to take the proper steps in waterproofing your masonry or brick buildings, especially chimneys, before winter hits. When water freezes it expands, which can cause damage and cracking to your masonry if not properly sealed. Masonry constructions materials like brick, concrete and mortar will deteriorate quickly when going through the freeze/thaw process. Even your roof flashing can rust and deteriorate with prolonged exposure to moisture.

Preventing Water Penetration

There are a number of ways you can prevent water penetration. For your chimney, you can invest in a chimney cap or rain cover. This is an inexpensive way home owners can protect the masonry around their chimney. Other things to consider are repairing or replacing damaged chimney crown, repairing deteriorated mortar joints, repair or replace roof flashing and using waterproofing agents on masonry. These formulas are 100% vapor permeable, which means that they allow the chimney to breathe. Water that has penetrated and the vapors produced when the chimney dries out or the water vapors produced during use are allowed to escape, while the waterproofing agent prevents water from entering from the outside.

roof flashing

Here are a few frequently asked questions about flashing and roof repair:

What is flashing? Flashing is just material — usually aluminum or galvanized steel — that’s used over joints in roof and wall construction to prevent water seeping in and causing damage.

Where do I need to install flashing? Flashing needs to be installed around all joints on the roof like windows and chimneys. This includes dormer windows, skylights and vents.

Why don’t roofing shingle manufacturer’s recommend re-using roof flashing when replacing a roof? There are many reasons but the short answer is because the nails don’t always go back into the same holes they were in originally. Although many people do reuse their flashing, it is not considered “best practice.”
