Residential Renovations
MLC BUILD specializes in comprehensive home renovations, focusing on structural upgrades, kitchen and bathroom transformations, and energy-efficient improvements. Our process includes detailed pre-construction planning, budget alignment, and contingency management to address unforeseen challenges. Clients benefit from advanced techniques like HEPA filtration systems and dust containment, ensuring minimal disruption during living-on-site renovations.
New Home Construction
We design and construct custom homes using high-performance building methods and sustainable materials. Our approach integrates architectural collaboration, precise budgeting, and cutting-edge technology like Festool Domino machines for seamless wood connections. Projects emphasize long-term durability through overbuilt framing and premium fastening systems, ensuring structural integrity for decades.
Specialty Projects
From noise-suppression walls to custom fencing, our specialty projects address unique client needs with innovative solutions. We apply double-wall framing techniques for sound dampening and use premium materials like cedar shake for aesthetic and functional enhancements. These projects maintain the same rigorous quality standards as our larger renovations and new builds.
High-Performance Building
Our high-performance construction incorporates advanced insulation, air-sealing techniques, and energy-efficient systems like hydronic radiant floors. We prioritize materials with low environmental impact while ensuring optimal indoor air quality. This approach reduces long-term energy costs and aligns with LEED sustainability principles for modern, eco-conscious homes.
Dormer Additions
We design and build dormers to expand living spaces, such as adding third-floor bathrooms or offices. Our process includes structural reinforcement with LVL joists and ZIP sheathing, ensuring seamless integration with existing architecture. Custom trim and historical accuracy in 1930s-era homes maintain aesthetic continuity while modernizing functionality.
