They placed their trust in us

    I worked with Instaltech G.L. to replace a front door, and I’m more than satisfied. The selection and quality of products in the store are truly exceptional. The advice I received was just as helpful, and it’s immediately clear that they take pride in a job well done.

    During the installation, it quickly becomes clear that no one is rushing or in a hurry to leave. The work is done meticulously, and we also discover a few issues with the installation of the previous door. Everything is corrected and done flawlessly. The final result is impeccable.

    Dominic Marsan

    An excellent company, very professional with a great team. They installed all my doors and windows, plus the exterior siding, within the agreed-upon timeframe. The products they offer are high-quality. I highly recommend them. Thank you, Instaltech.

    Jonathan Hébert

    Very satisfied! No surprises after the quote, sound advice, and a flawless installation! The work was done efficiently, meticulously, and professionally (contract for 12 windows, entire house).

    The employees didn’t leave any debris behind, and the owner ensures the quality of the installation. Top-notch work! I highly recommend them.
