I recently had the pleasure of working with AlphaTech Windows & Doors in Calgary, and I couldn't be more satisfied with their services. As someone who has collaborated with various windows and doors installation companies in the past, I can confidently say that AlphaTech stands out for its exceptional quality and professionalism.

From the initial consultation to the final installation, the entire process was seamless. The team at AlphaTech is highly knowledgeable and skilled, ensuring that every detail was meticulously handled. They provided a wide selection of high-quality windows and doors, catering to both aesthetic and functional needs.

What impressed me the most was their commitment to customer satisfaction. They were attentive to my specific requirements, offering customized solutions that perfectly matched my home’s design. The installation crew was punctual, efficient, and left my home spotless after completing the job.

The new windows and doors have significantly improved my home's energy efficiency and curb appeal. I highly recommend AlphaTech Windows & Doors to anyone in Calgary looking for top-notch products and exceptional service in the windows and doors industry. Their dedication to excellence truly sets them apart.

Replaced 3 sets of French Doors. Amanda was our salesperson, she came out to our home and was great to work with. They delivered ahead of schedule which was awesome. Walter and his crew arrived on time and did a great job with the installation. We LOVE our new doors, no more leaks and the quality is excellent. They did have to come back out for some touch up but they responded immediately and were back here within a couple of days and took care of everything! They look beautiful.
Thank you to Walter as well, professional and excellent at installation, he knows exactly what he is doing.
