What business owners worry about

A renovation should not cost you customers. This is how we keep the project under control.

  • Retail store renovation done after hours behind a temporary partition

    Closing the doors during construction

    Every day closed is lost revenue.

    We work around your business

    We check what can stay open, phase the work and schedule the noisy jobs outside your hours.

  • Steel stud walls and ductwork during an office fit-out

    Too many trades to coordinate

    Electrical, plumbing, HVAC and finishers who never talk to each other.

    One company runs every trade

    We manage the planning, permits, trades and inspections from start to finish.

  • New glass-walled meeting room in a renovated office

    A space that no longer fits

    Offices without meeting rooms and stores with the wrong flow.

    We redesign the layout

    Open offices, meeting rooms, partition walls and custom millwork.

  • LED panel light being installed in a commercial ceiling

    High power bills and poor light

    Old fixtures that cost too much to run.

    We upgrade lighting and systems

    LED retrofits, motion sensors and HVAC upgrades that lower operating costs.

    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.

    I’ve worked with CNG Contracting on several commercial inspections, and they’ve been outstanding from start to finish.
    The entire experience was professional, organized, and very educational. The inspection reports were clear, detailed, and easy to follow — not just technical data, but practical information that actually helps you make confident decisions.

    Claudio arrived right on time, and was extremely knowledgeable, he took the time to explain every part of the process. After the inspection, he personally walked me through all the photos and videos, breaking down each finding so I could fully understand what I was looking at. That extra step made a big difference.

    The detailed report I received afterward became more than just paperwork — it turned into a valuable guide I can use as a reference for my commercial project.
    It gave me full clarity on what to expect and how to plan each stage, from the first step to the last.

    I truly appreciate the transparency, care, and expertise that CNG Contracting brings to their work.
    It’s rare to find a company that combines professionalism with genuine customer care and integrity like this.

    I’d absolutely recommend them to anyone looking for a thorough, honest, and reliable inspection or construction service
