Cold upstairs rooms, drafty floors and high heating bills can point to air leaks or missing insulation. Souzet is a Holliston-based Home Performance Contractor participating in the Mass Save program. From our Washington Street office, we help local homeowners assess their homes, complete recommended insulation and air sealing work, and navigate available incentives. We also seal and insulate ductwork when those improvements are part of the plan.
Eversource and National Grid are Sponsors of Mass Save. If your Holliston home is served by either utility, Souzet can help you start with a no-cost Home Energy Assessment and find out which improvements and incentives apply. We review the home and the program requirements, then explain the recommended work and estimated cost before you decide. Eligibility and incentive amounts depend on your home, utility account and current program terms.
An under-insulated attic can make the second floor uncomfortable in every season and contribute to winter heat loss. We check existing insulation during the assessment, seal accessible air leaks and recommend attic insulation where it will help. Mass Save incentives may cover 75% to 100% of approved insulation costs, depending on eligibility. Your assessment will show what applies to your home.
Insulation works best when hidden air leaks are addressed first. We look for gaps around attic hatches, plumbing and wiring penetrations, and rim joists, then seal the accessible areas identified in the assessment. This can help reduce drafts and make rooms easier to keep comfortable. Recommended air sealing is typically completed at no cost after a qualifying Mass Save assessment.
Cold floors and hard-to-heat rooms can be signs of insulation gaps below or around the living space. Depending on the home, Souzet can insulate rim joists, basement walls, crawlspaces and exterior walls. The assessment identifies the right areas to address and whether the proposed work qualifies for Mass Save incentives.
When ducts run through an attic, basement or crawlspace, leaks and uninsulated sections can waste heated or cooled air before it reaches the rooms you use. We seal accessible duct joints and insulate ductwork where recommended, helping the system deliver air more effectively. The assessment shows whether either service belongs in your home's improvement plan.
A Home Energy Assessment is the first step. A specialist checks insulation, air leaks and heating equipment, then provides a written report with recommended upgrades, estimated costs and applicable Mass Save incentives. Souzet helps with the program steps and rebate paperwork if you choose to move forward. To get started, request an assessment through Souzet or call (833) 717-5001.
