Most basement windows are small and sit high on the wall. If you are planning a basement suite or a bedroom downstairs, that window usually has to get bigger. We do the whole job. We file the permit, cut the foundation, install the window and well outside and finish the wall inside. You deal with one team and get one written quote.
Licensed and insuredOur crews are covered while they work in your home.
Everything in writingScope, price and schedule agreed before we start.
Permits and inspectionsWe file the drawings and book every inspection.
These are the calls we get most often from homeowners in Brampton and Mississauga.

One small window near the ceiling, and the lights stay on even at noon.
We cut a larger opening and install a bigger window so daylight reaches the room.

The suite needs a second way out before anyone can live there.
We plan the window with the rest of your legal basement apartment and take care of the permit.

The old window is too small, and the basement project is on hold.
We enlarge the opening, install the new window and book the inspection again.

Leaves and snow fill the old well, and water gets in around the frame.
A new well, drainage at the bottom and waterproofing around the opening keep the water outside. If water also gets in somewhere else, see our basement waterproofing in Brampton page.

Everything from the first cut to the final cleanup is in one quote.
We cut the poured concrete or block foundation wall to the new size.
We add the header and the structural reinforcement the wall needs above the opening.

Claudio and his team are great at what they do and I wouldn’t hesitate, for a second, to recommend them to anyone who is looking for a great general contractor in the GTA.
My fiancé and I had the pleasure of having Claudio renovate our main floor and roof. While the reno process can be stressful, Claudio was there to help us every step of the way. It was clear early on that Claudio was thorough (spent 2+ hours with us building a detailed project plan, in person, before we signed a contract), communicative (shared updates with us almost daily and always responded to questions quickly), personable (friendly, easy to talk to and explained everything) and an overall fantastic contractor (quality final product and everything was on schedule).
My fiancé and I had reached out to several contractors before deciding to work with Claudio. While other contractors took weeks to respond and estimated 3-6 months before they could even start, Claudio started the project one week after we signed! From signature to completion the project took only six weeks, an impressive feat considering the amount of work we had done.
The new kitchen and living area are both functional and beautiful, Claudio truly turned our vision into a reality. We are extremely pleased with our new living space!
If you are looking for an amazing general contractor in the Greater Toronto Area, look no further – Claudio and the team at CNG Contracting’s the one for the job.
It was a pleasure engaging CNG Contracting. We were fortunate to have Claudio Marcelo Navarro, CEO, spearhead the project. His hands-on approach achieved timeliness, thoroughness, quality and price. Most important is that the work was well within our limited pensioners’ budget. Marcelo understood our needs by providing before and after pictures that passed all scrutiny, including that of the neighbours whose property he had to access. He and his team cleaned up all work area in a most professional manner.
Our senior citizens’ trade discount was built into the total project cost. There were no surprises.
Without reservation, we would hire CNG for our next house/backyard initiative.
I am very very confident to recommend CNG for any area of their business. A few years ago they did a complete basement construction and we were so pleased with everything, we immediately contacted them again, when had to remodel two bathrooms.And they will be returning soon to do work on my front porch.
Here is a short list of what to expect from CNG
1- delivered as promised on time and on budget.
2.- always there to answer any questions and to update on current and next step in construction.You know exactly how work is flowing.
3.- everything professionally done to construction standards.
4. -skilled crew deployed in their area of expertise, to ensure the
highest quality of job is done.
5 – quality material used .
6 – no cutting corners.
7. even after work was done, Claudio returned to touch up something in one bath at no cost, maintenance I should be doing.
8- Hire and enjoy PEACE OF MIND and NO REGRETS.
Thank you to CNG Contracting for their professional work in restoring our cracked steps. We are grateful that this has been fixed and pleased with the outcome.
Due to a very harsh winter and over time the cracks were becoming bigger. CNG came in and was able to fix the problem.
A special thanks to Marcelo and Sam, who did the work.
CNG were completely professional from the beginning to the end and I would recommend this company for any of your renovation needs. They are economical, friendly, and they do excellent work.
Still have a question? Call or WhatsApp us and we will answer it.

The price depends on the wall, the size of the window, how deep the well goes and how much finishing the room needs inside. Poured concrete and block walls are cut differently, and a suite can need more than one window.
We visit, measure and send you a written quote before any work starts. There is no obligation to go ahead.
Cutting a new or bigger opening in a foundation wall usually needs one. We prepare the drawings, file the application and book every inspection, so you do not have to deal with the city yourself.
Yes. We cut the concrete or block wall, install the egress window, add a well with drainage and take care of waterproofing and structural reinforcement. It is often the first step in a legal basement apartment, and we can build the rest of the suite too.
Not when the outside is done right. We set a new well, add drainage at the bottom and waterproof around the opening before we backfill. If your old well already lets water in, we fix that as part of the job.
It depends on the wall, how many windows you need and the permit. You get the schedule in writing with your quote, and one person keeps you updated until the job is done.
Yes. Most of the work happens outside and at one wall of the basement. We keep the site clean and safe while we work, and we clean up before we leave.
Yes. We are based in Brampton and install egress windows in Mississauga, Toronto and other nearby cities.
Yes. Most of our egress windows are part of a bigger basement job. See our basement finishing page for rooms and suites, or our exterior work page for drainage, grading and other outside jobs.

Send us a few photos of the window and the wall outside. We will visit and send you a written quote.
