When a Sunnyvale chimney leans, leaks, or draws badly, it is rarely random - soil movement opened the mortar, a storm moved the cap, or buildup sat through a mild winter and never got swept. We diagnose it on camera first and repair it with the right materials.

A chimney in Sunnyvale is not fighting a long winter - it is fighting clay soil that shifts under the masonry, heavy rain looking for a way in, storm damage up top, and long idle months in between. This is what we actually find, and what we check on every visit.
Winters here are mild, but the rain is not - long, heavy rains find every weak cap, cracked crown and failed flashing joint in Sunnyvale. Water down the flue rusts the damper, stains the firebox, and soaks masonry that then dries slowly in the heat. We trace leaks from the top down.
A Sunnyvale chimney can sit untouched from spring through fall, collecting dust, debris, nesting and moisture the whole time. Then the first cold front arrives and the fireplace gets lit with no check at all. A fall sweep and inspection catch what the idle months left behind, before that first fire does.
Long, hot summers bake chimney crowns, dry out sealants, and age cap metal across Sunnyvale, while sudden downpours test every crack the heat opened. Crowns that looked sound in spring can be split by fall. We check the crown, cap and flashing together, because heat and rain work on all three.
When clay soil moves unevenly, a chimney can lean or pull away from the house, opening a gap at the siding and cracks through the masonry in Sunnyvale. Early on, joint and flashing repairs hold; left alone, separation becomes a structural rebuild. Any new lean or gap is a reason to inspect promptly.

At least once a year if you burn at all regularly. Short, cool evening fires lay down glazed creosote faster than hot fires do, and an idle flue collects nests and debris all summer. The annual sweep clears the buildup and blockages, and checks the cap, crown and liner as well.
Do not light a fire, and do not spray into the flue yourself. Wasps and mud daubers nest in idle Sunnyvale flues, and the nesting blocks the draft, so a fire would push smoke and carbon monoxide into the room. We clear the flue safely, check the liner for damage, and fit a screened cap so it cannot happen again.
Get it inspected promptly. A lean usually means the soil under one side moved more than the other, and the same movement is cracking mortar and opening the joint where the chimney meets the house. Early movement can often be stabilized with joint and flashing repair; a lean left for years becomes a rebuild.
Yes. The liner keeps heat and exhaust gases inside the flue and away from the framing and rooms the chimney passes. Shifting masonry cracks clay tiles and opens gaps at the joints, letting both escape where they should never go. Liner faults are invisible from the firebox, which is why we diagnose them on camera first.
Not until it has been inspected. In Sunnyvale an idle flue collects nests, debris and moisture, and the masonry may have cracked from soil movement while nobody was watching. One camera inspection tells you whether the flue is clear and the liner sound - before the first fire tests it the hard way.
No — and be wary of anyone who does. Every chimney fails differently, so a phone price is a guess that changes at your door. Our estimates are free: a tech looks at the actual problem, then gives you one clear price before any work starts.
