Most people call us about one of these four situations. Each one ends the same way, with a basement apartment built properly and signed off.
A letter about the basement shows up and you are not sure what to fix or how fast.
We visit, go over what the basement needs and prepare the drawings. Then we do the work and stay with it until the final inspection.
The suite looks finished, but nobody knows what is behind the drywall.
We open what needs opening, keep what is sound and rebuild the rest to the approved drawings.
An empty basement could help with the mortgage, but only if the suite is legal.
Layout, bedrooms, kitchen, bathroom and a private entrance, all built with a permit and ready for a tenant.
Drawings, permits, trades and inspections feel like four projects at once.
You talk to one person from the first visit to the handover. We coordinate the paperwork, the trades and the inspections.
Every suite is different, but these are the parts we plan, build and get inspected on almost every job.
We measure the basement, draw the plans and handle the permit application and follow-up.
Larger bedroom windows cut into the foundation, with a proper window well. See our egress window installation page.
We rework bulkheads, ducts and pipes to gain headroom where the space needs it.
Heating, cooling and ventilation planned for the suite, so both units stay comfortable.
Fire-rated drywall, doors and connected alarms between the two units.
A side or rear entrance with its own door, so your tenant comes and goes without walking through your home.
New circuits, pot lights, a kitchen and a full bathroom, all roughed in and inspected.
Insulation, sound control, drywall, flooring and paint to finish the suite.
Every suite we finish gets its own page in our project gallery, with photos of the rooms, the kitchen and the bathroom. Take a look before your visit so you can point out what you like.
Most basement renovations cost $40 to $60 per square foot. A legal second unit adds a kitchen, a bathroom, fire separation and permits, so we quote each one after we see the space. Our basement finishing cost guide shows what changes the price.

| 1,000 sq. ft. basement | $40,000 to $60,000A finished open space with standard finishes. |

Four steps, with one person keeping you updated from start to finish.

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.

Claudio explained everything from the beginning and gave us a detailed estimate showing everything we discussed for our basement renovation.

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.
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.

Thank you
Claudio and your CNG Contracting Team!!!
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!
