Included with every project

The Waltbridge Homes Care Commitment

At Waltbridge Homes, our commitment goes beyond construction. We believe in delivering quality workmanship, maintaining open communication and remaining responsive to our homeowners after project completion.

Included at no charge

Complimentary Waltbridge Homes Care Commitment included

Cleaning of both furnaces after completion and a six-month post-possession walkthrough.

Complimentary cleaning of both furnaces

At the completion of construction, Waltbridge Homes provides a complimentary, one-time cleaning of both the furnace servicing the main home and the furnace servicing the basement suite.

This is part of our standard construction-completion practice to help address construction-related dust and support HVAC system cleanliness.

One complimentary service covering both furnaces, scheduled once after construction completion. The confirmed cleaning scope is set out in your project agreement.

Six-month post-possession walkthrough

Our relationship with homeowners continues beyond possession. Approximately six months after project handover, Waltbridge Homes arranges a follow-up walkthrough to listen to client concerns, review the completed basement and identify eligible workmanship items that may require attention.

We believe listening, responding and taking responsibility are essential parts of delivering a positive construction experience.

Scheduled approximately six months after possession. Eligible items are addressed under the applicable workmanship warranty and service terms.
