Work approach: upfront assessment and tailored recommendation

The company states that it does not apply a single product to every project. During the free on-site estimate, it evaluates the actual condition of the attic, exterior walls, crawlspace, rim joists, pole barn, garage or commercial building. Before recommending spray foam, cellulose, fiberglass or a combination, it considers the structure, existing insulation, air leakage, moisture conditions and project goals. The company maintains that this approach addresses both thermal performance and air-leakage control, in order to achieve more stable indoor temperatures and reduce unnecessary heating and cooling losses.

Estimate and quote process

The process described by the company consists of three steps: the customer tells us about their project by phone or through a form; an on-site assessment is carried out; and a detailed written quote is provided. The company states that estimates are free and with no obligation, and that it does not use high-pressure sales tactics. It also notes that it can guide homeowners on which insulation and air-sealing improvements may qualify for energy-efficiency rebates or incentives.

Signs of poor insulation

Among the problems the company associates with insufficient insulation or air leaks are: upstairs rooms that stay too hot, cold floors over a crawlspace, drafts in walls and rim joists, and high heating and cooling bills.
