Consider a breathable water repellent
A compatible treatment can help reduce rain absorption into suitable exterior masonry.
Start with the water source
Which problem are we solving?
A stain is a clue, not a diagnosis. Water can enter through the masonry face, chimney top, or roofline. We check the relevant accessible areas before recommending a water-repellent treatment.
Repair the masonry first
Treatment cannot replace missing mortar or rebuild a damaged brick face.
Address the chimney top
These openings need their own repair or replacement.
Check the flashing
Coating the brick will not close a failed roofline joint.

Treatment after assessment
How masonry waterproofing fits the repair plan
A compatible breathable water repellent can help reduce rain absorption into suitable exterior masonry while allowing water vapor to move through it. It is considered after the water source and any repair needs are understood.
Open joints, damaged brick, crown cracks, and flashing defects need their own assessment. We explain those items separately in the written scope. Explore masonry repair or chimney cap options.
Find the likely entry point
Review your symptoms and check the accessible cap, crown, flashing, mortar, and brick.
Explain the repair plan
Identify any needed crown, flashing, cap, or masonry work separately from treatment.
Prepare suitable masonry
Complete approved repairs and follow the chosen product’s surface and drying instructions.
Apply and document
Treat the approved area with a compatible vapor-permeable product and record the completed scope.
What treatment can and cannot do
A breathable water repellent can help suitable brick and mortar shed rain. It does not repair a cracked crown, failed flashing, missing cap, or open mortar joints. The right work depends on what is allowing water in.
Know the scope and price
What affects a waterproofing estimate?
The amount and condition of exposed masonry, roof access, preparation, and any separate cap, crown, flashing, or mortar repair affect the scope. We show the recommended work and total price in writing before you decide.
If you are comparing options for a larger repair, you can also review financing information.

They came out quickly for an estimate and did the work in the same week. They were very professional and explained everything they would be doing before the job started. I highly recommend them to anyone looking for honest, reliable, and high-quality service. Thank you for making this such a great experience!

2 reviewsI had an emergency situation that needed immediate help. Franklin chimney came the next morning and estimated the job for me. The estimate was totally in line with the research other companies that I had done and Franklin came out the next day to do the job. I am so relieved to have this major problem in my house corrected. They were great communicators, on time, clean, fair, professional, and did a great job I could not recommend them more.

3 reviewsWe needed a level 2 chimney inspection on a quick timeline for our HOA. Franklin Chimney came out in less than 48 hours. Booking was very easy and price was significantly better than competitors. Our technician Madi was very efficient and made sure we had the report we needed.

1 reviewI called Franklin Chimney when I noticed flies coming out of my wood burning stove. Maty was here within an hour. He sent a drone up on my roof and discovered a few holes in the mesh that was easy access for birds or squirrels to enter. He sent 2 guys out the next day. They were friendly, efficient and fast. They removed 4 birds and a squirrel. Put a new cap on chimney and sealed it off with mesh. They were done in about 2 hours. I highly recommend Franklin Chimney....thank you for doing a great job!
