Built By a Family,
Not a Franchise.

GSR is a father-and-son team with 13+ years in the field — not an office. Our own crew is on your site daily, licensed trades handle the rough-in, and Raj manages every project himself — checking every stage in person. We stopped competing on price a long time ago. We compete on standard.

$200
A Day, If Late

Six Promises, In Your Contract —
Late and We Pay You $200 a Day.

Before we break a single wall, you get a fixed price and a fixed completion date, both locked in your contract. Your price is locked. If we finish late — we pay you $200 a day, up to $5,000. It's written into your contract before we start — our money on the line, not a slogan. Plus a 3-year warranty, a free design package, weekly updates with the owner’s direct number, and permits & inspections guaranteed — six promises, in your contract.

Fixed-price contract Fixed completion date $200/day if we’re late Full design included 3-Year workmanship warranty Bathroom Leak & Mold Guarantee

We build 20+ basements a year — but we only take on a handful of custom showpieces at a time.

*Full guarantee terms are spelled out in your signed contract before any work begins.

How It Works

First Call to Final Walkthrough.

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 — typically 1–2 months, depending on your city. 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 You Ask

Straight Answers.

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.
Construction: personal-use basements take roughly 4–10 weeks on site; legal second units start around 10 weeks, depending on scope. Design & permits are a separate stage before construction — typically 1–2 months, depending on your city's approval times. We lock your construction completion date in writing — and if we miss it, we pay you $200 a day, up to $5,000.
Yes — completely. We handle the architectural drawings, permit submission, and every city inspection. You never touch a form.
Yes. Through our partner Financeit, you can spread the cost into flexible monthly payments instead of paying all upfront — subject to approval. We'll walk you through the options on your free call.
Before we start, you get a fixed price and a fixed completion date — both in your contract. Your price is locked. If we finish late, we pay you $200 a day, up to $5,000. It's a real financial commitment, not a marketing line.
Custom basement renovations of every kind across Toronto & the GTA — home theatre basements, basement wet bars, home gyms, media walls, basement bathrooms, and full open-concept basements taken from bare concrete to finished. One crew, one fixed price, one completion date.
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 Raj personally manages every single project — no site managers passed between jobs.
