The Martha’s Vineyard Savings Bank branch next door to the Edgartown Post Office remains closed because of water damage due to construction.

Hours at the main office downtown on the corner of Main and School streets have been extended on Fridays until 5:30 p.m. and Saturdays from 8 a.m. to noon.

“I really don’t know for certain when it’s going to open,” bank president Paul Falvey said last week of the branch at the Triangle. “We’re very conscious of the fact that it’s a busy branch and very important to our customers . . . but we want to make sure it’s done right and safe for our employees and our customers. It might end up being an improved branch because of it.”

He said water entered the bank from the construction project underway to build five apartment units above the bank and the post office next door. Mr. Falvey said the bank now expects to do additional work to make the office more accessible for people with handicaps.

“Work is going to need to be done in that branch in order to get it reopened and it may drive us to correct a few other deficiencies there,” he said.

He said building owner Charles Hajjar has taken some responsibility for repairs and lost rent. “He’s done a nice job reaching out to us,” Mr. Falvey said. “Do we wish it didn’t leak in the first place? Of course we do.”

In other savings bank news, a new Chilmark location at Beetlebung Corner opened for business on April 4. A grand opening celebration is planned for early May.

The new branch has a drive-up teller window, an ATM and more parking, the bank said in a press release.

The savings bank purchased the new building, a former Santander bank branch across from the community center, last June. The previous Chilmark branch was located around the corner; the savings bank will shift all operations to the new location.
