Local stone chimney repair for Rio Grande Park homes

Preparing joints before filling

Preservation guidance wants the old mortar cut out cleanly to a flat, squared back, and the joint washed free of dust and loose grit. At the time of filling, joints should be damp with no standing water.

Dust and a rounded back are what let new mortar pop out later. Our crew cleans each joint to a square, sound back and dampens it just before filling, section by section.

Moss, algae and dirt on stone

Shaded sides of a stone chimney can hold moisture long enough for moss and algae to grow in the joints and on the stone. The growth holds water against the surface and can darken the stone.

We start with the gentlest cleaning that works, water, a mild detergent and a soft or bristle brush, and avoid pressure and harsh chemicals on the stone and joints. Where growth keeps returning, the findings note the moisture that feeds it.

What a stone chimney estimate lists

A clear stone estimate separates the work so you can see and approve each part. Ours list the stones to reset or replace, the joints to repoint and how deep, the mortar type and how it will be matched, and any access equipment.

Cap, crown, flashing, drainage and flue items sit on their own lines beside the stone work. Each has its own price, and the total does not change later without your approval.

• Joints to repoint and depth
• Mortar type and color match
• Access and site protection

Stone chimney notes in a home inspection

Home inspection reports sometimes note loose stones, open joints, hollow veneer or missing drainage at the base of a stone chimney and recommend further evaluation.

We inspect the chimney, explain what each note means for that chimney and put the repair options and prices in writing. Buyers and sellers can read the same scope, which makes the conversation between them easier.

Scheduling stone work around cure and cleaning

A stone job has three parts on the calendar, the working days, the first days of curing and the wait before any real cleaning. Planning them together avoids surprises, such as a planned party with fresh joints still covered.

We book the work around your plans and the forecast, tell you when the covers come off and give you the date when the stone can be cleaned beyond a dry brushing.
