Short answer

Mice reach attics in both cities the same way, at the roofline. What differs is the house. Older Calgary homes tend to leak where brick meets soffit and around decades of add-ons; newer Airdrie homes tend to leak at vented soffits, garage roof tie-ins and vents. We inspect each house on its own.

## Typical weak points

|  | Older Calgary homes | Newer Airdrie homes |
|---|---|---|
| Siding | Brick, stucco, wood | Mostly vinyl |
| Soffits | Brick–soffit seam, wood soffits | Vented aluminium or vinyl soffit returns |
| Roofline | Additions, re-roofs, old chimneys | Garage roof meeting the house wall |
| Penetrations | Many, from decades of upgrades | Fewer, but often unsealed vents |

These are common patterns, not rules.

## Same weather, same problem

Calgary’s Chinook swings can take a wall through several freeze-thaw cycles in one winter, and each cycle works sealant and trim joints loose. Airdrie sits just north of Calgary and gets the same swings.

## How we seal an attic

1. Inspect the roofline and attic hatch.
2. Treat mice already inside, planned around your household.
3. Close each joint with copper mesh, sealant or metal screens.
4. Photograph and document each closed joint.

## Guarantee

The [Gap Guarantee](https://www.frameworkpest.ca/guarantee/) covers re-entry through a specific joint we closed and documented, during the first freeze-thaw season after the visit. It is not a whole-house seal.

## Questions

### How do mice get into attics in Calgary and Airdrie?

At the roofline: soffit returns, roof and bath vents without metal screens, flashing gaps where a lower roof meets a wall, and utility penetrations.

### Are Airdrie homes different from Calgary homes?

Often. Much of Airdrie's housing is newer, with vinyl siding, vented soffits and attached garages. Calgary has more older inner-city homes with brick, additions and decades of penetrations. Each has its own usual gaps. Every house still needs its own inspection.

### Do you serve Airdrie?

Yes. We work across Calgary, Airdrie, Cochrane, Chestermere and Okotoks.

### What does attic mouse work cost?

Mouse work is typically $100–$1,500 depending on severity, after inspection, GST extra.

### Will you replace my insulation?

No. Heavily soiled insulation goes to an insulation contractor, and we will tell you if that is what we see.
