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.

Straight Answers to the Questions Everyone Asks

Personal-use basements typically run $40,000–$70,000, and legal second units run $50,000–$95,000+ — depending on size, layout, and finishes. You get a fixed price in writing before any work starts, so there are no surprises.
Personal-use basements take roughly 4–10 weeks. Legal second units start around 10 weeks, depending on scope and permits. We lock your completion date in writing — and if we miss it, we pay you $4,000.
Yes — completely. We handle the architectural drawings, permit submission, and every city inspection. You never touch a form. And right now, with the Summer Special, your permit + plans are free when you sign before August 31st.

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.
We build within about 50 km of Brampton — including Brampton, Mississauga, Toronto, Etobicoke, Vaughan, Caledon, Oakville, Milton, Georgetown, Markham, Richmond Hill, and Hamilton. Keeping our service area tight is how we keep a supervisor on every site, every day.
