How It Works

A Clear Process, Every Step of the Way

No disappearing acts, no surprise invoices — here's exactly how your project goes.

01

Phone Consultation

We start with a detailed call — your vision, the scope, and rough pricing — so you know exactly where you stand before anyone visits. No pressure, no obligation.

02

Site Visit & Space Planning

Once you're ready to move forward, we visit your home, measure the space, and plan the layout around your actual basement — not a guess.

03

Design & Permits

We create your custom floor plan and handle the full permit application. Every project is built to Ontario Building Code — inspections passed, paperwork handled.

04

Build & Finish

Licensed trades handle the rough-in; our in-house crew handles every finish — flooring, tiling, painting, trim. Then we walk through it together.

Before we start, you get a fixed price and a fixed completion date — both in your contract. If we finish late or go a single dollar over budget, we pay you $4,000. It's a real financial commitment, not a marketing line.
