What Energy-Efficient Remodeling Means Today
Building science-led upgrades that elevate comfort, durability, and value
Lynch + Company, LLC delivers high-end energy-efficient additions and remodeling rooted in building science. Our team fuses architectural intent with performance engineering to create high-performance homes and spaces that are quieter, healthier, and more durable—lowering operating costs while elevating daily comfort. Professionalism, quality, and integrity guide every decision, from feasibility through final commissioning.
We prioritize an envelope-first strategy: continuous insulation, meticulous air sealing, high-performance windows and doors, and vapor-smart assemblies that manage moisture in all seasons. Right-sized HVAC, balanced ERV/HRV ventilation, and precise dew point control ensure consistent temperatures, clean indoor air, and resilient finishes that stand the test of time.
Transparent planning, precision execution, measurable outcomes
Every project begins with a thorough assessment: goals, budget, and constraints, followed by diagnostics such as blower-door testing, infrared scanning, and duct leakage evaluation. We pair field data with energy modeling to inform design, optimizing assemblies, mechanical systems, and daylighting while aligning performance targets with your aesthetic and lifestyle.
During construction, you can expect transparent schedules, site protection, and coordinated trade sequencing that preserves airtightness and thermal continuity. Our QA/QC checklists, mockups, and performance tests verify results, and we document details—from window flashing to ventilation commissioning—so you have clear proof of the home’s elevated performance.
Quality that endures for generations
Built to last for generations, our assemblies emphasize durability: rainscreen cladding, continuous weather barriers, robust flashing at all penetrations, and clean roof-to-wall transitions that shed water and resist wind-driven rain. Material selections favor longevity, repairability, and low embodied carbon, supporting responsible development. On site, we practice stewardship of the land with erosion controls, tree protection, careful runoff management, and low-impact staging.
High-performance living enhances quality of life. Expect even temperatures, exceptional comfort, and superior indoor air quality through balanced ventilation, high-MERV filtration, and low-VOC finishes. Our craftsmanship extends beyond what you see—precise tolerances, straight lines, and hidden protections that safeguard structure and finishes.
We future-proof your home with renewable-ready infrastructure: PV and battery prewiring, EV charging, smart controls, and conduit pathways that simplify solar or wind integration. Our strong relationships with trusted trade partners ensure expertise at every step, while our commitment to integrity keeps budgets, timelines, and performance targets aligned.
