6 DECK LEAK REPAIRS
Deck Leak Repairs
We Handle Across Seattle
A leaking deck rarely leaks where the water shows. We trace the water from the stain or the drip back to where it gets in, then repair that point and the wood it has already damaged.
Your written estimate identifies the fixed scope before work starts, and your workmanship warranty terms are written into your agreement.
01 / LEAK REPAIR
Deck Over a Room or Garage
When a deck sits over living space, a garage or a carport, the waterproof layer under the surface is what keeps the room below dry. We check the membrane, its edges and seams, the drains and the flashing at the house wall, find where the water gets in and price the repair in writing after the free inspection.
Ask for the leak source, the repair method and the wood to be replaced to be listed separately in your quote.
02 / LEAK REPAIR
Ledger & House-Wall Flashing
The ledger is the board that ties the deck to the house. Missing or failed flashing there sends rainwater behind the siding and into the house rim. We open the area, check the wood and the connection, and flash it again so the water runs away from the wall.
A ledger reset or another change to the house connection may need a Seattle permit; we check that at the inspection.
03 / LEAK REPAIR
Water Dripping Under the Deck
Water falling through the boards onto a patio, an entry or storage below is a drainage question. We compare the ways to keep the space under the deck dry, from an under-deck drainage system between the joists to a different surface, and fit them to your deck.
Tell us how you use the space under the deck, so the quote matches what needs to stay dry.
04 / LEAK REPAIR
Rot Caused by Water
Water that sits on or under a deck rots boards, joists and posts from the inside. We replace what is soft, check the joists and beams around it and fix the cause so the new wood stays dry.
Our guide on a rotted deck: repair or replace shows how we decide when rot means a rebuild.
05 / LEAK REPAIR
Door Thresholds & Wall Connections
Many leaks start where the deck meets a door, a wall or a post that passes through the surface. We check the threshold, the transitions and the seals around anything that goes through the deck.
If water has reached the room below, mention it when you call so we know where to look first.
06 / LEAK REPAIR
Standing Water & Surface Drainage
Puddles that stay on the deck after rain point to a surface without enough slope, blocked drains or gaps packed with debris. We clear the cause and set the surface so the water runs off.
Ask about cleaning the gaps and drains as part of a maintenance plan.
Request a deck leak inspection.
Tell us where you see the water: a ceiling stain, drips under the deck, soft boards or puddles on top. Ask about inspection availability and a written repair quote.

7 SIGNS OF A LEAKING DECK
7 Signs Your Deck
Is Leaking
A deck leak can run for months before it shows. These seven signs tell you where to look and what to show us when you call. Our guide to a rotted or leaking deck explains what each one means for the wood underneath.
Deck inspiration photograph · condition and repair planning.
01
Stains or drips on the ceiling below
Brown rings, bubbling paint or drips in a room, garage or carport under the deck mean water is getting through the surface or its edges.
02
Water dripping under the deck after rain
Drips onto a patio or entry below show water passing between the boards. Whether that matters depends on how you use the space underneath.
03
Soft boards near the house wall
Rot that starts at the wall usually means water is reaching the ledger. Check the joists and the connection before replacing the surface.
04
Puddles that stay after the rain
Standing water points to slope, blocked drains or packed gaps, and it keeps the wood wet long enough to rot.
05
Stains or peeling paint on the siding below
Streaks under the deck line or paint lifting on the wall below can mean flashing that sends water behind the siding.
06
Mold, mildew or a musty smell below
A damp smell in the room or storage space under the deck is a sign that water is getting in and not drying out.
07
Rust streaks at screws and hangers
Rusting screws, joist hangers or ledger bolts show long contact with water. Look closely at the wood they hold, and stop using the deck if the ledger is pulling away from the house.

Send the deck location and tell us where you see the water.
FIX THE LEAK OR REPLACE THE DECK?
Fix the Leak or
Replace the Deck?
Most leaks come from one failed point: a flashing, a seal, a drain. Sometimes the water has been getting in long enough to rot the frame. The free inspection tells you which one you have, before you spend anything.
01 / REPAIR
A leak repair makes sense when…
The water gets in at one point and the joists, beams and ledger around it are still solid. We fix that point and replace only the wood it damaged. Deck repair in Seattle ↗
02 / REPLACE
Replacement makes sense when…
Water has rotted the joists or the ledger, the deck sags, or the same spots leak every winter. A new deck lets you build in the drainage and the flashing from the start. Deck replacement in Seattle ↗

SEATTLE RAIN AND DECK LEAKS
Leak Repairs Made for
Seattle’s Wet Season
Long rainy seasons, evergreen shade and slow drying keep water on a deck for months at a time. A small gap in the flashing or a blocked drain that would dry out elsewhere can keep leaking all winter here.
For shaded decks in Fremont and Ravenna, look at how long the surface stays wet. Decks over garages and rooms on the hillsides of Queen Anne and Madrona need a close look at the waterproof layer and the house connection, and waterfront homes around Magnolia and West Seattle add wind-driven rain. We confirm what applies at your address.
- Flashing at the house wall. Lapped so water runs away from the siding and the ledger.
- Drains and slope. Checked so water leaves the deck instead of sitting on it.
- Joist and ledger moisture protection. Drainage and protection tape detailed as part of the repair.
- Compatible fasteners and connectors. Stainless or coated hardware selected for the wood and the exposure.

The leak inspection is free. Seattle deck repairs start at $199 and board replacement at $125 per board, with up to 25% off qualifying projects. Your exact price comes from the free on-site inspection, once we know where the water gets in.
A useful leak repair quote separates the fix at the source, such as flashing, a seal or a drain, from the wood that the water has already damaged. Access, deck height and how much wood needs replacing change the cost.
We start where the water shows, a ceiling stain, a drip or a soft board, and work back to where it gets in. That means checking the surface and its seams, the edges, the flashing at the house wall, the door thresholds and the drains, and looking from below where it is safe.
Call us and describe the stain and when it shows up, for example only in heavy rain. A deck over living space relies on a waterproof layer under the surface, and the leak is usually at an edge, a seam, a drain or the house wall. The free inspection finds the point and the written quote prices the repair.
On most decks the boards are spaced so rain can pass through, so some water below is normal. If you want the space under the deck to stay dry, we compare options such as an under-deck drainage system or a different surface and fit them to your deck.
Yes. Water that keeps reaching the ledger, the joists or the boards rots them from the inside, often before anything shows on top. That is why we check the wood around the leak and replace what is soft as part of the repair.
Yes. The on-site inspection is free and comes with no obligation. You get a written price and decide on your own time.
Send photos of the deck, the spot where you see water and the area below if you can reach it safely. That is enough to talk through the likely scope on the phone. The exact number comes from the free visit, because the source of a leak is often hidden under the surface.
