Storm Alert

With the fourth Nor’easter in nearly three weeks right on our door step, we have hundreds of crews positioned across the region should the storm impact our system. Remember to keep safety a priority – before, during and after the storm. Be sure to have a supply of bottled drinking water and canned food handy. Power problems can sometimes interrupt public water supply systems or disable well pumps. It is also a good idea to check on elderly family members, neighbors and others who may need assistance during an outage period.

A better business climate starts with a well-insulated building. Increase comfort and energy savings with these simple tips:

  • Make sure all exterior walls, ceilings, roofs, and wall cavities are adequately insulated.
  • Common air leakage points to check and seal include:
    • The areas around plumbing, electrical, and duct work in exterior walls.
    • Any chases open to spaces like an attic.
    • Gaps between interior and exterior walls and ceiling sheetrock.
    • Any sheetrock areas, including between interior and exterior walls and where sheetrock is sealed to the subfloor.
    • Openings around windows.
    • Floors, including cantilevered floors and band joist areas in floor systems.
    • Kneewalls in cape-style structures.
    • Joints between existing buildings and additions or modular buildings.
  • Add a reflective roof coating which keeps your building cooler by absorbing less heat.
