Outdoor problems we fix every week

Toronto winters are hard on a house. These are the jobs homeowners call us about most.

  • Interlocking pavers being laid for a new driveway

    Cracked concrete and sunken walkways

    Trip hazards at the front door and a driveway that gets worse every winter.

    We rebuild it on a proper base

    Driveways, walkways, steps and patios in concrete or interlock, set on a compacted base so they stay level.

  • New aluminum eavestrough and downspout installed on a brick house

    Water pooling near the house

    Overflowing eavestroughs and soil that slopes the wrong way send water into the basement.

    We fix the drainage

    New eavestroughs and downspouts, regrading and foundation sealing that move water away.

  • Cedar deck with a pergola in an Ontario backyard

    A backyard you never use

    Bare grass, no shade and nowhere to sit outside.

    We build you an outdoor room

    Custom decks, covered patios, pergolas and landscaping built for the way you live.

  • House front with new stone veneer and a new front door

    A tired, dated front

    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.

    We hired CNG Contracting to redo the entrance at our church. They did an incredible job, on time and on budget. We are very satisfied with the results. Claudio kept his word and was very helpful, he also provided us with frequent updates during the process.

    I would definitely recommend using CNG contracting for any construction needs you may have.

    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.

Do you offer full exterior renovations in Toronto?

Yes. We do stucco, siding, exterior painting, concrete driveways, walkways and stairs, interlock, railings, brick pointing, eavestroughs, soffits and fascia, windows, front doors, landscaping and grading, and larger basement windows for egress.

Do you build decks and pergolas?

Yes. We build custom decks, stairs, covered patios and pergolas. You can see some of them in our recent projects below.

Can you install larger basement windows for a legal suite?

Yes. We cut the concrete or block wall, install a legal egress window, add a window well with drainage and take care of waterproofing and structural reinforcement. It is often the first step in turning a basement into a legal basement apartment.

How can I improve my home’s curb appeal?

New interlock or concrete, a rebuilt porch with new railings, stucco or siding, a new front or garage door, exterior lighting and fresh paint. We help you choose the upgrades that change the look the most for your budget.

Can you replace my front door and windows?

Yes. We install fibreglass and steel entry doors with sidelights, and casement, slider and fixed windows. All installations are ENERGY STAR rated, with full-frame replacement for better insulation.

Do you replace roofs?

Yes. We install asphalt shingle, flat and metal roofs with proper ventilation, flashing and waterproofing, and we install and replace Velux skylights.

Do I need a permit for exterior work?

Some jobs need one, like structural porch work, new window openings or certain decks. All our exterior work is done with the permits and code compliance it requires.
