Black Swan Construction LLC.

This is a small residential outfit. The owner works on the tools, and the state puts the crew at one to three people. The state lists Daniel Derkach as a principal since 2020 and Jasmine Derkach since 2026. Washington registration through L&I dates to 2020, and the Idaho registration through the Division of Occupational and Professional Licensing followed in 2024. Around Spokane, Spokane Valley and Liberty Lake, that adds up to hands-on masonry and repair work on houses, not large commercial or industrial building. Before comparing quotes on masonry or repair work, write down exactly what you want done. Note the wall, chimney, steps or foundation section involved and roughly how large it is. Note whether old material comes out or new work goes over it, and what finish or matching you expect for existing brick or stone. Ask each bidder to say who handles demolition and debris, whether the permit is included, and how freeze-thaw damage found mid-job will be priced. Spokane winters are hard on mortar joints and porous stone, so ask how each contractor plans to schedule cold-weather work. With the same written scope in every bid, the quotes become comparable.
