Repair methods vary depending on the type of siding you have, but most are fairly easy to fix. Renailing loose sheathing, replacing rotted elements and patching any holes or gaps on the underlying surface will help in maintaining your siding after it is repaired.

Height considerations: If your home has multiple stories (levels), your contractor may need to have special equipment to get to the taller areas of your home. Remember, siding can be heavy and awkward to work with, so they may not be able to carry it up ladders.

Look for clues: It will help your service professional if you can pinpoint the nature of the problem before repairs begin. For example, look for obvious clues, such as overgrown tree roots or damaged gutters that let water drain onto masonry surfaces. Also check the slope of the surrounding landscape to see if it needs to be regraded to direct water away from the foundation.
