Yes, most of the time. If we can't do it we will recommend a qualified contractor who can. This is the most important part. It is the only way to prevent the problem from happening again. Typically we use sheet metal to repair holes or flash corners.
Most repairs are in hidden areas and the flashing is barely visible.
We use our specially designed custom attic vent covers to screen attic vents. We use hardware cloth to screen any odd shaped vents. And now we have new specially designed vent screens specifically for your dryer vents. We also carry a variety of chimney caps or we can order custom sizes. If we see something that we think could be a problem in the future, we will bring it to your attention and let you decide if you would like us to repair it or not.
