### How much does attic finishing cost in Ajax?

In Ajax, attic finishing typically runs based on scope and materials. Pro House Maintenance gives every Ajax homeowner a free, fixed-price written quote before any work begins, so there are no surprises.

### Does my attic have enough headroom to finish?

### How does attic finishing affect my home's energy efficiency?

Significantly. An uninsulated attic is the biggest source of heat loss and gain in most homes. Finishing it with spray foam or continuous batt insulation often reduces HVAC bills by 15–20% as a direct benefit of the project. Properly air-sealed attic assemblies also reduce drafts and improve comfort on every floor below.
