Chimney Maintenance and Repair Costs: Chimney Flashing, Spalling

While the chimney is often ignored, it’s actually one of the most important structures of your home. Both its exterior and interior should be maintained.

Many people forget that the fireplace is only as good as the chimney above it. The moment you realize that your chimney is not working as well as it should, you must take action to have it fixed.

After all, a faulty chimney will not only negatively affect your fireplace, but it also compromises your safety. Being proactive beats being reactive. Keeping the chimney in good condition now will save you from costly repairs in the future, and might save your life.
