Critter Control of Des Moines installs chimney caps to prevent critters from getting into chimneys.  Raccoons will live in chimneys and raise their young.  Birds and squirrels will fall into a chimney and become trapped.  The following pictures are examples of the types of chimney caps we have installed.  Special order chimney caps are available when needed, otherwise we carry most standard size chimney caps with us at all times.  If you are hearing scratching sounds coming from your fireplace, give us a call at 515-287-0419!
