Custom Basement Renovations in the GTA

Q: How long does a personal basement renovation take?

Most personal spaces take 4–10 weeks depending on scope and features. We lock in your completion date in writing — and we're on the hook for $4,000 if we miss it.

Q: What if the finished space doesn't match what I wanted?

That's why we include a full design package upfront — floor plan, material board, and layout — that you sign off on before we build a single thing. What you approve is what gets built.

Q: How much does a personal basement renovation cost?

Most GTA projects fall between $40,000–$70,000 depending on size and finishes. Fill out our form and we'll give you a rough estimate for your specific space — no commitment.

Q: What if you go over budget or miss the deadline?

We pay you $4,000. It's written into your contract before we break ground — an actual financial commitment that keeps us fully accountable to you.

Sound Familiar?

Why most homeowners regret their basement renovation — and how to avoid it.

You're not the first one this has happened to — and it doesn't have to happen with GSR.

01Problem #1

You described your vision clearly — what got built looks nothing like it

You showed photos, explained the layout, discussed finishes. Then you walked into a basement that looks like a generic rental — and changing it now costs more than building it right.

02Problem #2

The quote was $38K. The final bill is $60K. With no warning.

"Unforeseen conditions." "That wasn't in scope." By the time you're halfway through you're too invested to walk away — and the contractor knows it.

03Problem #3

Three weeks in, the calls stop. The crew disappears.

On-site every day for two weeks, then nothing. The project that was supposed to take 10 weeks is now at month 5 with bare framing and exposed wires.

04Problem #4

It looked good at first. Until it didn't.

Six months after handover — tiles lift, drywall cracks along the seams, paint peels near the bathroom. You call. No answer, no warranty.
