Before you book a window installer across Markham, ON
- Pre-emptively raise neighbour-courtesy expectations if your Markham parcel sits adjacent to occupied homes — debris drift, noise leak, and access-shared fences all generate complaints that contractors should mitigate before homeowners hear about them.
- Clarify hazardous-material handling (lead paint, asbestos, vermiculite) up front — older Markham stock disproportionately surfaces these mid-project, and pricing must reflect the abatement protocol.
- Get the proposed-vendor-list for fixtures, tiles, fittings on paper so visible substitutions cannot quietly downgrade the deliverable mid-job.
