Olmos Brothers General Contractors | Roofing Services in Seattle, WA 98168

We handle a range of residential excavation needs, including trench digging for utilities, drainage solutions, and foundational site preparation. Our team is experienced in navigating Seattle's varied soil conditions to ensure your project has a solid start, whether you're adding an accessory dwelling unit (ADU) or installing a new sewer line.

For the persistent moisture and algae growth common in our climate, we offer professional roof cleaning and treatment to safely remove stains and prevent regrowth. For skylight leaks, we perform thorough inspections to identify the source—often failed flashing or sealants—and provide precise repairs or replacements using quality materials designed to withstand Seattle's rain, ensuring your home stays dry and protected.

Managing separate contractors for site work and concrete can lead to coordination delays. As a full-service general contractor, we oversee the entire process—from the initial excavation and trenching to the final concrete pour and finishing. This integrated approach ensures seamless workflow, consistent quality control, and a single point of accountability, saving you time and providing peace of mind.
