Chimney water repellent work, explained plainly
If you are thinking of doing it yourself
Treating a chimney yourself means working at height, often on a roof, with a product that must be kept off glass and plants. The product choice also matters, and some store products form films that can trap moisture.
If you plan to do it anyway, read the product data carefully and do the repairs first. Stay off wet or steep roofs. If you would rather not climb, the free inspection in Dolphin Isles will tell you what the chimney needs. You can then decide with the facts in hand.
Being there for the assessment
You do not need to climb anything during the waterproofing assessment. What helps is telling us why you are asking. Dark brick after rain, flaking faces, a past treatment or a leak all point the visit in different directions.
If you cannot be home, someone who knows the history can stand in, or you can tell us by phone beforehand. We explain the findings in person or by phone afterward. The written estimate follows either way, with the repairs and the treatment on separate lines.
Two chimneys, two separate assessments
If your house has two chimneys, each one is assessed on its own. They may be built from different materials, face different weather and carry different repair histories. One may need treatment while the other does not.
The estimate lists each chimney separately, with its own repairs and its own treatment line if it needs one. You can then decide on each. Doing both at once saves setting up access twice, but only if both genuinely need the work. We will not pair them just to fill a visit.
Trying the repairs alone first
Brick industry guidance suggests a sensible order: make the repairs, then wait and see whether the water problem is already solved before deciding on a coating. Often the repairs do most of the work.
If you prefer that approach for your chimney in Dolphin Isles, we price the repairs now and leave the treatment as an option for later. After some heavy rain, you can look at how the chimney behaves. If faces still soak up water, treatment can follow. If not, you have saved the cost.

Your chimney waterproofing questions
Can a repellent close cracks in the brick or the joints?
It cannot. Penetrating repellents work inside the pores, and anything wider than a fine hairline is beyond them. Open joints are repointed, cracked units replaced and gaps sealed before treatment. We list those repairs separately, with the reason for each.
Can I apply a chimney sealer from a hardware store myself?
You can, but read the product data first. Some store products form films that trap moisture, and every product needs repairs done beforehand and glass and plants protected. Working at height on a roof is the other risk. The free inspection tells you what the chimney needs either way.
How will I know if the treatment is still working?
Look at the chimney during and after rain. Treated faces should shed water and dry evenly. If a face darkens and holds water again, the treatment may be fading or something else has changed. A maintenance visit can check it and the parts it depends on.
