How much does a renovation cost in Ajax?

It depends on scope and finishes. As a guide, bathroom renovations typically run $15,000–$26,000, kitchens $24,000–$55,000, and finished basements $32,000–$65,000, with whole-home and addition projects quoted individually. After a free in-home consultation we give you a detailed, fixed-price quote — the real number, with no vague allowances.

How long does a renovation take in Ajax?

Timelines depend on scope. A bathroom typically takes 3–6 weeks, a kitchen 4–8 weeks, and a basement 6–10 weeks, while whole-home renovations and additions run longer — especially when a permit is required, since municipal review adds time. We give you a week-by-week schedule before work begins so you always know what to expect.

Can you remove a load-bearing wall in my Ajax home?

Yes — and this is where our approach stands apart. GMC is led by an owner who holds a Master's degree in Structural Engineering, so we assess how your home carries load before touching a wall, and arrange the stamped structural drawings and permit the work requires. Opening up a closed layout is one of the most common — and most structurally sensitive — requests we handle across Ajax's older and newer homes alike.

Which Ajax neighbourhoods do you work in?

All of them. We renovate homes across Pickering Village, Nottingham, Applecroft, Southwood, Central Ajax, Duffin's Bay, Northeast Ajax and the waterfront communities — from historic character homes to the town's newer subdivisions. We serve Ajax and the wider Durham Region.

Why choose GMC over other Ajax renovation companies?

GMC is led by an owner who holds a Master's degree in Structural Engineering, so every project is planned around how your home actually carries load — the structural surprises that stall other renovations get caught up front. Combined with fixed-price quotes, a written workmanship warranty, and a 5.0-star rating across 85+ Google reviews, that gives you a level of confidence most renovation crews can't match.

Q: Do I need a permit to renovate my home in Ajax?

It depends on the work. Cosmetic updates — new cabinets, tile, fixtures or finishes in the same layout — usually don't need a permit. But moving plumbing, changing electrical, removing a load-bearing wall, finishing a basement, adding a legal second suite, or building an addition require a permit from the Town of Ajax's Building Services. As a licensed contractor, GMC handles the entire permit process for you, and arranges the stamped structural drawings your project requires.

Built to Last — Not Just Installed

What makes us different starts before the first material is ordered. GMC Construction is founded and led by an owner who holds a Master's degree in Structural Engineering — so every project is approached with a genuine, advanced understanding of structure, load-bearing changes, drainage, and moisture protection. Most renovation companies focus only on how a space looks. We start with what's underneath, because that's what determines whether your renovation lasts five years or twenty-five.

Renovation Contractors in Ajax

When it comes to home renovation Ajax, no two homes are alike — from the historic character homes of Pickering Village to the established neighbourhoods of Nottingham and Applecroft and the newer subdivisions of Central Ajax, each has its own character. GMC Construction Inc. has spent 15+ years working across all of them — kitchens, bathrooms, basements and whole-home renovations for Ajax homeowners who want the job planned properly, priced honestly, and built to last.

What sets us apart in a crowded market: GMC is led by an owner who holds a Master’s degree in Structural Engineering. Before we quote a wall removal, a basement underpinning, or a second-storey addition, we understand how the house actually carries load — which is why our projects don’t run into the structural surprises that stall other renovations. It’s a structure-first approach no other Ajax renovation company offers.

Renovating in Ajax: What to Know

Ajax’s housing stock ranges from historic to brand new, and each brings its own renovation realities. The character homes of Pickering Village are among the oldest in the area and often need careful updating of layouts, wiring and plumbing. The established homes of Nottingham, Applecroft and Southwood are prime candidates for kitchen open-ups, basement suites and additions. The newer subdivisions of Central Ajax, Duffin’s Bay and Northeast Ajax are larger and more open, where the work is usually finishing a basement, building a custom kitchen, or adding an ensuite. Lakeside properties near the waterfront sometimes carry grading and drainage considerations for additions.

Basement-finishing and secondary-suite projects are especially common across Ajax’s family neighbourhoods — turning a large lower level into legal living space or a rental suite, with the proper permits and structural planning a structure-first contractor gets right up front.

Do You Need a Permit to Renovate in Ajax?

Renovation permits in Ajax are issued by the Town of Ajax’s Building Services, within the Region of Durham framework. Cosmetic work — replacing cabinets, tile, fixtures and finishes in the same layout — generally doesn’t require a permit. But moving plumbing, altering electrical, removing a load-bearing wall, finishing a basement, adding a legal second suite, or building an addition typically do. As a licensed contractor, GMC manages the permit process for you and arranges the stamped structural drawings your project requires — so the work is done to code and passes inspection the first time.

Ajax also permits Additional Residential Units, and as part of Durham Region most detached, semi-detached, and townhouse properties can add a second unit — commonly a basement apartment — subject to the Town’s zoning by-law and a building permit. A legal suite must meet the Ontario Building Code and Fire Code, including minimum ceiling height (which may call for underpinning where the basement is too shallow), egress windows, and fire separation, and electrical work requires a separate permit from the Electrical Safety Authority (ESA). Lakeshore properties in south Ajax can also carry conservation or grading considerations, which we confirm up front rather than mid-project.

I recently used GMC Construction for a project, and I couldn’t be happier with the experience. The team was incredibly professional, responsive, and reliable. They arrived promptly, completed the work efficiently, and the final cost was even better than I expected. Their workmanship and attention to detail were outstanding, and it was clear they have a highly skilled and experienced team. The entire process was smooth from start to finish. I highly recommend GMC Construction to anyone looking for quality work, fair pricing, and excellent customer service. I would definitely use them again!

Ernika Naghizadeh

We had our bathroom done at a very reasonable price! It looks amazing, first time since we’ve gotten such reliable work done in our house! 10/10 experience!

Niall Flynn

Had a great time dealing with Max and the work he did tiling our kitchen! I’d planned to do it myself but decided to hire Max instead and thank god I did because the results were great!

I had an absolutely amazing experience with GMC Construction Inc. You never really know what you’re getting when you take the risk of hiring someone new - but I was pleasantly surprised by the level of care and attention to detail Max put into his work. GMC handled a few repairs in my home, including installing a new sink and fixing my door. I also had a few other fixes that I hadn’t initially discussed, and when I brought them up, Max moved quickly and took care of everything without hesitation. He went above and beyond, spending time to find the right tools, making sure everything ran smoothly, and even following up afterward. Max and his wife are truly a rare find: professional, fair with pricing, and they genuinely care about the quality of their work. Highly recommend if you're debating on who to trust with your home! :)

Krystal

Max was the perfect guy to install things around our home. He showed up on time, was very personable & friendly. He cleaned up any mess he made and did such a fantastic job. I will definitely be hiring him again for anything else that comes up in the future. Thanks again Max! 😊

Ben Bakhtiarynia

Max is a highly professional and knowledgeable contractor. He completed several jobs with expert attention to detail and wonderful efficiency. He is also very friendly and will offer you additional solutions to improve the jobs he starts. I would highly recommend him and his work. He did a beautiful job mounting my TV, soundbar, and making it all look super clean by running the chords through the wall. My entertainment experience has improved so much thanks to his care and hard work.

Staci J

I had the best experience with GMC construction they were very quick and so nice. I had my mirrors installed and old ones removed. Would definitely recommend.
