A sealed crown and a stainless cap with a screen keep rain, birds and embers where they belong. The cheapest repair on the chimney and the one that prevents the expensive ones.

The crown is the concrete slab on top of the chimney. The cap is the metal hood over the flue. Together they are what keeps rain out of the masonry and birds out of the flue, and they are the first thing to fail on a Hill Country chimney.
A missing cap means rain runs straight down the flue onto the damper and the smoke shelf, and a screenless cap is an open door for birds and squirrels. A cracked crown lets water into the brickwork itself. Both are cheap to fix and expensive to ignore.
The exact scope depends on your fireplace, the flue and what the inspection finds.
Every job begins with a free professional inspection. The final scope depends on the home, the system and what we find.

A general home inspection notes that the fireplace exists. It does not go up the flue, check the crown or find where the dryer vent ends. What to check before closing, and what it costs when you do not.

Yes. It keeps rain, animals and embers out. A cap with a screen is the single cheapest thing that protects the chimney.
The concrete top of the chimney. Sun, rain and freezes open cracks in it over the years, and water gets into the brick below.
Hairline cracks are sealed with a flexible crown coating. A crown that is broken through or crumbling gets poured new.
Yes. Tied off, on the roof, with photos of everything so you never have to go up.
Cap and crown seal in about an hour. A new crown takes a morning and a day to cure.
