A basement is the cheapest square footage in the house. These are the problems that keep it unused.
Concrete walls, cold floors and a smell nobody wants to live with.
Insulation and waterproofing go in before the framing, so the finished space stays warm and dry.
A basement suite only pays off if it is legal and passes inspection.
We build the suite with its own entrance, egress windows and permits, and we walk you through every step.
Every city has its own rules, and the drawings are a project of their own.
We measure, draw the plans, submit them and follow up with the city until the permit is approved.
Guests, teenagers or tenants all end up using the one upstairs.
A full bathroom or powder room, with the plumbing roughed in to code.

We hired CNG Contracting for a full home and basement renovation of our bungalow, which included disability-friendly access, new electrical throughout the house, new water lines from the city to the house, and new sewage lines to the city main connections. The project started on January 1st and was completed on March 20th, right on schedule.
From the initial planning and design to the final inspection and handover, Claudio and his team were professional, responsive, and easy to work with. They took the time to understand our needs and answered every question clearly. Most importantly, he was patient and helped complete the details to claim the appropriate disability rebates and refunds.
We know that no renovation is ever perfect, but what truly sets CNG Contracting apart is how quickly and effectively they handled every challenge that came up. Every concern was addressed immediately and with care.
Our new basement (with wet bar and rental-ready rough-ins) and main floor kitchen, staircase, and added powder room turned out beautifully and exactly where we needed them, as we envisioned.
Even after completion, when minor attention was needed, Claudio personally followed up right away and ensured everything was taken care of with his team.
We confidently give CNG Contracting 5 stars and recommend them to anyone looking for a serious, dependable contractor who stands behind their work and truly protects your investment.
When we first met Claudio, we had a great experience as he walked us through the entire project process according to what we needed; he made a drawing on the spot and accurately created the estimate.
Our questions were answered as we went along the process, including the selection of materials. He showed us which were high-quality and worth paying for.
When we started the project, the CNG Contracting team showed up on time, and everything was according to schedule. They had a process assuring the completion stage was on time, and we had no delay.
Something very important to us was that we had control of the finances; the payment schedule concluded after the stages, not before. Also, it was noticeable the system was created to protect our investment and we believe that the transparency that CNG Contracting runs their business is very reliable and trustworthy giving us access to a follow-up system where we could keep an eye on the project from the pictures and videos uploaded regularly.
Our experience with Customer service was perfect, whenever we had a question or need, any time of the day, we contacted Claudio and had all our questions explained and answered.
The CNG Team had the house protected from day ONE, covering floors/ staircase/ hallways and creating containments to minimize the dust throughout the project; overall, the house was clean, safe and organized every day.,
At the end of the project, we had a Professional (PDI) inspection and warranty included for any minor adjustments or touch-ups needed, as well as a 2-YEAR WARRANTY for all our plumbing / electrical and HVAC installed AND INSPECTED by CNG.
If you want to be surprised and impressed with things you were not expecting, CNG is the team to hire! They go above and beyond your expectations, no doubt about that; they are a very passionate team of guys who love what they do, respect your home, and protect your investment.
That’s why We would only recommend CNG Contracting to anyone looking for a (AAA) licensed, insured, respectful, honest, reliable, organized and professional people to do any renovation project in your home, from bathrooms, kitchens, basements, or creating an open concept adding value to your home as we did with ours.

We had a leak in our basement in May of 2022 which caused quite a bit of damage, this was mainly used as a play area for my two sons ages 5 and 2. With a lot of back and forth for months with the preferred insurance company’s contractor which clearly showed a lack of urgency on their part to repair the damages and frankly silently refused the work.
Giving the preferred insurance company’s every opportunity to fix the damages I was forced to find my own contractor in mid October of 2022 (yes, you read correctly 5 months later). With no where to turn I did a google search and came across Claudio’s company CNG Contracting. At first, I was hesitant and gave Claudio a high-level outline of my situation, which he was very honest and direct with me which put me at ease. Once he understood the situation, he came over to assess the damage and I have to say I was very impressed!
He explained how the process works and how he operates. You will receive an estimate with a timeline and cost brake down. You’ll also receive pictures showing the progression of the project (start, middle and finish). You get a real time update as to how things are going from day to day which was VERY accurate! Claudio’s crew was very clean, polite, courteous and their craftsmanship speaks for itself as it at a very high level!
I would highly recommend CNG Contracting as they do what they say and follow through. CNG Contracting is one of the good guys!
Claudio explained everything from the beginning and gave us a detailed estimate showing everything we discussed for our basement renovation.
Always keeping us up to date on every phase of the project and following the deadlines he gave us on the initial meeting.
The GNG team was very respectful, they have great communication. The team work very clean, they cleaned the work area every day, they were very prepared and created a very safe environment.
They cleaned our basement at the end, Claudio made sure the final product was more than what we were expecting. We are very glad to work with CNG contracting.
We will definitely recommend CNG contracting to family and friends and we are looking forward to call Claudio for our kitchen remodeling.
Claudio came to do a very professional and thorough presentation for my basement project with his laptop and computer program . The session was very educational and a real eye-opener.
Great organization to work with, very good communication and clarity on the work to be performed. Very happy with the work done
