Waterproofing work for chimneys in Three Lakes
Framed chimneys have nothing to treat
Some chimneys are a metal flue inside a framed box covered in siding or stucco. There is no brick to waterproof. Water problems on these chimneys come from the metal cover at the top, the siding joints and the finish.
If your chimney is framed, we tell you that a masonry repellent does not apply. We look instead at the cover, the collar around the flue pipe and the wall covering. Any repairs there are priced under their own names, so you are not sold a treatment the chimney cannot use.
Moss and algae come off before the repellent
Moss, algae and small plants on a chimney hold water against the brick and block a repellent from soaking in. They have to come off before treatment. Roots in mortar joints can also open the joints further.
We remove growth with a method suited to the masonry, avoiding harsh treatments that could damage the surface. Where roots have opened joints, those joints are listed for repointing. The treatment then goes onto clean, sound masonry, rather than over growth that will lift it.
How a waterproofing job is scheduled
A waterproofing job often runs in stages. Repairs come first, then time for new mortar to cure. Cleaning follows, then time for the masonry to dry. The treatment goes on last, in a dry weather window.
We set out those stages in the estimate, without inventing exact dates, because weather and curing decide them. You know what happens at each step and why. If you would like the stages spread across separate visits for cost or convenience, we can plan it that way.
Questions to raise at the visit in Three Lakes
A waterproofing visit in Three Lakes is a good time to ask anything you are unsure about. It helps to have your questions ready, such as whether the brick really needs treatment and what should be repaired first.
You might also ask how the product will look, how long preparation will take and what happens if it rains. We answer each in plain words. If a question needs checking, such as how an old coating will behave, we tell you how we will find out.

Repellent and sealing questions from Three Lakes
Can you treat a chimney that has been painted?
A clear repellent cannot reach the pores through paint, so it would do little. The choice is between caring for the paint and removing it, and removal carries its own risks for the brick face. We explain both before recommending either.
Should a planned new roof go on before the chimney is treated?
Usually, yes. Finishing the roof and the chimney flashing first avoids roof work marking treated brick and overspray marking new roofing. Tell us your roof plans, and we schedule the treatment to follow, with the new roofing protected during application.
Is it worth protecting the brick on a chimney we do not use?
It weathers the same as one in use. Rain soaks its brick, and water that gets in can damage the masonry and the house around it. Repairs come first either way, and a breathable repellent can follow where the brick absorbs too much.
