Question 1

How do you calculate project costs?

Accepted Answer

We use current market rates for high-quality materials and skilled labour in Durham Region. Every estimate includes a detailed breakdown of tasks so you know exactly where your money is going.

Question 2

Is the initial consultation free?

Accepted Answer

Yes. We offer a free first meeting to look at your space and talk about your goals. After that we provide a clear price range for your specific project.

Question 3

Do you offer fixed-price contracts?

Accepted Answer

Most of our projects use fixed-price contracts. This means the price we agree on is the price you pay, unless you decide to change the scope of work later.

Question 4

What happens if material prices go up?

Accepted Answer

Once we sign a contract, we lock in the material prices for you. We order supplies early to make sure your budget stays safe from market changes.

Question 5

How long will my renovation take?

Accepted Answer

Small jobs might take two weeks, while large additions can take months. We give you a full schedule before we start so you can plan your life around the work.

Question 6

Will I have a dedicated project manager?

Accepted Answer

Yes. You will have one main person to talk to. They will be on site often to check quality and keep you updated on our progress every day.

Question 7

How do you keep the job site clean?

Accepted Answer

We clean up at the end of every single day. We use floor protection and dust barriers to keep the rest of your home safe and tidy while we work.

Question 8

Do I need to move out during construction?

Accepted Answer

For most room renovations you can stay home. For very large projects like whole-home guts, we might suggest staying elsewhere for a short time for your comfort.

Question 9

What areas do you serve?

Accepted Answer

We serve all of Durham Region including Oshawa, Whitby, Bowmanville, Ajax, Pickering, Newcastle, Clarington, Scarborough, Stouffville, and Peterborough.

Question 10

Do you handle permits and inspections?

Accepted Answer

Yes. We submit the plans to the municipality, get the permits, and schedule all required inspections to ensure your home is safe and the work is done to code.

Question 11

Can you help with the design phase?

Accepted Answer

Yes. We work with designers and architects to help turn your ideas into professional drawings before we start building.

Question 12

Do you do commercial construction?

Accepted Answer

Yes. We offer commercial services for offices, retail spaces, and restaurants alongside our residential renovation work.

Question 13

What kind of warranty do you provide?

Accepted Answer

Every Cornerstone project is backed by a 5-year written workmanship warranty. If something we built fails because of how it was installed, we fix it at no charge.

Question 14

What if I find a problem after you leave?

Accepted Answer

Contact us directly. We respond to warranty concerns within 1 to 2 business days and will schedule a site visit to assess the issue at no cost to you.

Question 15

Are you insured and WSIB compliant?

Accepted Answer

Yes. Cornerstone Construction carries full liability insurance and all our workers are covered by WSIB. This protects you and your home completely.

Question 16

Do you offer maintenance tips?

Accepted Answer

Yes. At the end of every project you receive a full Owner's Manual with care and maintenance instructions for every material and system we installed.
