Our waterproofing approach, one step at a time
The written record of the treatment
When the work is finished, you receive a written record of it. It names the product, the faces treated, the repairs done beforehand and the date of application. It also notes any area left untreated and why.
Keep it with your home papers. Before anyone applies another product later, the record tells them what is already on the brick. That matters, because some treatments do not combine well. It also helps judge, down the line, whether a renewal is due.
Reaching the chimney for treatment
Treating a chimney means reaching every face to be treated, usually from the roof and sometimes from ladders or staging on the ground for an outside chimney. Access depends on the roof pitch, height and surface.
Mention anything that sits under the chimney, such as a patio, flower beds or a skylight, so we can plan where ladders stand. Gates, dogs and parked cars matter too. We sort out access before the application day, so the dry weather window is not spent setting up.
The first heavy rain after treatment
The first heavy rain after treatment is a good moment to look at the chimney from the ground. Water should bead and run off the treated faces, and the brick should dry evenly afterward. Areas that darken and hold water deserve a note.
If you see something unexpected, tell us. It may be an area the treatment did not reach, a patch that took it differently or a new crack. We would rather hear about it early and check it than find out at the next maintenance visit.
Footing and cover on the roof during treatment
Treating a chimney usually means working from the roof around it. Tile and some other roofing can crack under careless footing, and overspray can mark the surface. The roof needs as much protection as the windows below.
We plan where we will stand and where equipment will rest, and we cover the roofing close to the faces being treated. If a tile is damaged during the work, we tell you and deal with it. The roof around the chimney is left as we found it.

Your chimney waterproofing questions
Is chimney waterproofing the same as painting the brick?
No. Paint forms a film over the masonry and changes its look. A penetrating repellent soaks into the pores, keeps liquid water out and lets vapor escape. On a chimney we recommend only the breathable kind, and the estimate names the product.
Can one face be treated without doing the whole chimney?
Yes, where only some faces absorb too much water. Treating the whole stack gives an even look and even protection, while treating the worst faces may cost less. The estimate lists the faces included, and the test area shows how each one responds.
Will the treated brick still let moisture out?
With a breathable repellent, yes. It keeps most liquid water from soaking in while letting water vapor leave through the face. That matters on a chimney, because moisture reaches the masonry from inside as well, and a sealing film could hold it in.
