Zion Evangelical Pembroke, Ontario Sometimes, not a lot of work  is necessary. We did some work on this church in 2007. Keeping the elements, especially water out of a masonry structure is vital to it surviving the tests of time. These tests are repeated, day after day by the freeze thaw cycles that occur. One of the bestways to prevent damage, is to keep the water out. If you call us when you first notice that water is getting into the structure, the less expensive  it is to remedy.
