As a homeowner, one of the best things that you can do to secure your home from animals and water damage is to cap your chimney. An uncapped chimney is an open invitation for animals and water damage. Portland Fireplace Shop stocks many standard size chimney caps. They are heavy-duty caps and are more than strong enough to keep raccoons and water out and fit tightly to prevent bats from getting through. They are also very reasonably priced and available in round, square or rectangular sizes.
