Full-Frame vs Insert Window Replacement for Florida Concrete Block Homes

Why The Difference Matters In A Concrete Block Home

In a concrete block home, the replacement method affects more than appearance. It changes the scope of work, the water control details, and sometimes the code path the project has to follow.
