Our work is focused on long-term durability, correct building practices, and preventing repeat failures. Whether the issue involves siding transitions, deck ledger connections, roof penetrations, or plumbing wall cavities, we diagnose the problem at its source.

About us

Mikhail Makrushin

...Business owner....
I help homeowners in King County and Snohomish County, Washington, correct CONSTRUCTION DEFECTS and prevent recurring damage. My goal is to make homes DURABLE and RELIABLE while accounting for the local climate, site conditions, and project constraints.
Much of my work involves repairing wood structures damaged by MOISTURE. I restore framing, sheathing, and other parts of the home, investigate the CAUSE of deterioration, and address the conditions that led to it.
After starting my business in Washington in 2020, I began noticing RECURRING PROBLEMS across different properties: rotted wood, moisture buildup, mold, and concerns about indoor air quality. I encountered these issues in relatively new homes as well as older buildings that had RECENTLY BEEN RENOVATED.
That experience led me to look more closely at both workmanship and construction detailing—how walls and roofs are assembled, how WATER DRAINS, how air leakage is controlled, and whether materials have a way to DRY.
During an inspection, I pay particular attention to connections and transitions where different building components and protective layers meet:
  • Windows and doors. I check the condition of the wood beneath the opening, the presence of sill pans and head flashing, and how the opening’s flashing connects to the wall’s weather-resistive barrier. Water that gets in must have a path OUT.
  • Behind the siding. Exterior cladding is part of the wall’s protective system. Behind it, I assess the sheathing, the continuity of the weather-resistive barrier, and whether water can DRAIN and materials can DRY.
  • Deck-to-wall connections. I examine the ledger board, fastener penetrations, flashing, and beams extending through the exterior wall. Damage at these connections can affect both the deck and the home’s framing.
  • Roof-to-wall intersections. I check the STEP FLASHING and KICKOUT FLASHING that direct runoff away from the wall and into the gutter.
  • Attics and ceiling assemblies. Finding the source of moisture means looking beyond roof leaks. Moist indoor air can also enter through gaps in the ceiling and around service penetrations. AIR SEALING, insulation, and ventilation need to be considered together.
  • Basements and crawl spaces. I assess roof runoff, grading, drainage, and protection from ground moisture. These issues need to be addressed BEFORE damaged areas are covered with new finishes.
I made it my goal to understand why these failures occur and how to prevent them during repairs. That is why my work starts with finding the CAUSE. Replacing deteriorated wood should go hand in hand with restoring the affected connections, protective layers, and paths for water to drain.
I also pay close attention to how repairs and insulation change the way an existing home performs. Adding insulation can reduce heat flow to certain layers of an assembly and change their ability to DRY. Improving energy efficiency therefore needs to be considered alongside rain protection, air leakage control, and water vapor movement.
To me, a quality repair means restoring the damaged structure with a clear understanding of how it will DRAIN, DRY, and PERFORM after the project is complete.

Water damage inspection, mold remediation, and structural repair across Redmond, Bellevue, Kirkland, Sammamish, and Mercer Island.


Visible mold is a sign of a deeper MOISTURE issue — not the rOOT problem.
If the source isn’t identified, the damage will continue to SPREAD.
We help uncover the cause and define the RIGHT repair APPROACH.
