Maple Valley, King County
On a Maple Valley chimney, flashing repair is priced from $330 up to $1,500. At $330 the metal is still good and only its caulk line gets redone. At $1,500 every step piece and counter piece comes off a steep or tall roof and new metal goes on. Flashing means the folded sheet metal covering the seam where roof meets chimney; a large share of chimney leaks start there.

The usual Maple Valley house was built around 2001, the Census Bureau's median for the city, so its original flashing and the sealant along it are now past twenty years old. Sealant is the first part to give up. It dries, shrinks and pulls away from the brick or siding, leaving a thin gap that faces the weather. And the weather here comes from one side for most of the year: WeatherSpark finds the wind blowing mainly from the south from September 8 to April 30, which are also the wet months.
Every chimney flashing repair we do in Maple Valley includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowStorm winds push rain uphill and sideways. The Western Regional Climate Center writes that speeds of 40 to 50 mph can be expected each winter in the interior valleys of western Washington. Under those gusts water is driven behind flashing that would shed a vertical shower. Tree litter adds a second problem. Needles and leaves drift against a chimney's upslope face, hold water against the metal and let it creep under the shingles. A third is chemical: Oregon State University Extension cautions that zinc sulfate moss treatments corrode copper, so a roof treated for moss can lose copper flashing early.
Stains inside show where water ends up, not where it gets in. We follow the path from the attic to the roof and photograph the opening.
Sound metal with failed caulk is resealed. Rusted-through, loose or wrongly lapped metal gets replaced. Which of the two applies, and on what evidence, is written into the quote.
Debris comes out, shingles are lifted where needed and the old sealant is removed down to clean surfaces.
New pieces are lapped so water runs over each one, set into the mortar joints or behind the siding, and sealed.
A hose test checks the repair where it is safe to run one. You receive before and after photos.

Four steps, each one on paper — so you always know what happens next.
Choose a genuine opening on the crew's calendar. Confirmation is immediate.
Liner, crown, cap, flashing and masonry examined in order — each finding photographed.
One document, plain numbers, covering only the work your chimney genuinely needs.
The repair is completed, then handed over with before-and-after photos of every item.
$330 to $1,500. Cheapest is a plain reseal. Complete new metal, steep pitches and chimneys wide enough to need a diverter on the uphill side are at the top.
Often both. The leak is at the seam between the two trades. We trace it with photos so the cause is visible, whichever side it turns out to be on.
Only if you can do it safely from a ladder at the eave. Otherwise leave it. We clear that area on every roof visit, and it is worth doing each fall on a wooded lot.
The diagnostic visit is $99 plus tax. Accept our quote afterward and we deduct that $99 from what the repair costs.
A $99 on-site inspection, a written quote before any work, and photos of every item we touch.
