Our stone chimney repairs in Mission Bay
Mortar that gives way before the stone does
Repointing mortar should be softer and more vapor-permeable than the masonry around it. That is the central point of the National Park Service guidance on repointing. If the joint is harder than the stone, stress and moisture move into the stone instead.
Softer stones then crack or flake at their edges while the hard joint stays intact. We choose a mortar suited to the stone on your chimney, and the estimate describes it in plain words. Strength alone is not the goal, because a joint is meant to be the part that wears.
Joints where stone meets other materials
Where stone meets siding, trim or another finish, the joint needs to allow movement and stay sealed. The manufactured stone guide calls for flashing and sealant at penetrations and at transitions between materials. Old sealant is cut out completely before new material goes in, since fresh sealant does not hold well on old.
We check those joints for cracks, gaps and missing sealant. Resealing them takes little time and shuts off an easy route for rain. It is listed as its own item, with the materials named, so you can see what went into each joint.
Lifting stones to reach the flashing
On some chimneys, the flashing at the roof is tucked behind the lowest stones. Repairing it properly can mean lifting those stones and setting them back afterward. Those stones are numbered or laid out in order so each goes back where it came from.
When that is the case, the flashing work and the stone resetting are planned together, so the flashing is finished before the stones cover it again. Flashing is its own service with its own line on the estimate, and the stone work needed to reach it appears right beside it.
Simple habits that protect stonework
Keep sprinklers pointed away from the chimney and gutters near it clear, and watch for stones that change position. If a stone looks loose, keep people clear of it and leave it where it is. A quick look from the yard after strong wind or heavy rain is enough to spot most changes.
Avoid pressure washing the stone or using acid cleaners yourself, and resist filling joints with caulk. Each of those makes a later repair harder and can mark the stone. Describe anything unusual to us, and we will say whether it needs a look.

Answers on repointing chimney stone
How do you tell natural stone from manufactured stone?
Weight, edges, the back of a loose piece and the way joints are laid all give clues. Manufactured stone is a cast product with its color concentrated near the face. We tell you what we believe you have and why.
Do you cover open areas if the work takes more than a day?
Yes. Before we leave each day, any area where stones are off is sheltered from rain, and removed stones are stored safely until they go back. Loose debris goes with us rather than staying on the roof.
Is there a discount for booking stone work soon after the inspection?
It does. Book the stone work within 72 hours of your own free inspection and 10% comes off that service. Each price on the estimate is shown in full, so the saving is easy to see.
