In order to completely seal the entire chimney area from top to bottom, these are the steps that should be taken. Starting on the very top of the chimney, we check your chimney caps and vents to make sure they are completely sealed and raised. If the top of the chimney is worn, cracking or not sloped to drain properly, it is necessary to rebuild the concrete area that is the top of the chimney. Power washing clean all of the brick and mortar is essential before chiseling out all of the loose, cracked, or old mortar. Then on to TUCK AND POINT (Filing in all the holes, gaps and cracks in the brick) with matching mortar. We can rebuild the cricket if necessary. We reseal the flashing and replace if necessary before adding 3 coats of waterproof sealer.

These steps are the only sure way to stop all the problem areas with a chimney or a cricket. Water will come right through the brick on an old untreated chimney. All of these steps are done brick by brick and can be time consuming to do properly. Sometimes to create a matching mortar we have to mix up to 5 or 6 batches until we get the right color. The power washer must be held straight onto the brick when washing to clean every crack and crevice. On chimneys with a cricket it is a very good idea to rebuild a bigger cricket over the existing structure for long term longevity.
