Before having chimney services done, you want to make sure that you are asking the right questions. First, be sure to ask if the company is certified and insured. This is crucial as it protects both you and your property from any liability when it comes to damage to your property or even injuries. Second, you may want to consider asking about what services they recommend. While you may have an idea of what your chimney needs, the professionals may have better ideas. Finally, ask for any references or examples. This will allow you to get a better idea of what services they offer.
