Our Entry Door Installation Process

Site visit, inspection and estimation

For entry doors, we inspect the frame, sill, and surrounding structure, then measure carefully so the new door and hardware fit snugly.

Door selection and preparation

We help you choose materials, glass inserts, colour, and hardware like smart locks, then order the door to your measurements and schedule the work so downtime is minimal.

Installation, sealing, and trim

We remove the old door, install and shim the new frame, hang the slab, and seal, weatherstrip, and trim everything so it closes smoothly and keeps out drafts and noise.
