Our 90 yr old house had 29 yr old windows that were in pretty bad shape and after a cold winter it was time to do something about it. The job included replacing 5 windows and a garden door with single-hung vinyl windows and a sliding patio door. All were argon-filled and Energy Star rated.
After several weeks of self-education and research we called in 3 highly reputable and well reviewed companies listed on Homestars. One company can be considered large, one medium sized and Sobol Inc which was the smallest.
Let me interrupt the review by saying that even getting to the point of choosing 3 companies was very difficult as there are is so much conflicting information in the marketplace about different kinds of windows and their respective performance, which manufacturer's produce quality products, which retailer/installer to use. In short it was a stressful process from beginning to end, but taking the time to educate myself before calling for estimates really helped.
Pre-sales - We obtained quotes from all 3 companies. Archiel from Sobol was the first to respond to our call and arranged for a prompt on-site inspection. He was knowledgeable and provided many practical suggestions to my ideas and questions. A reasonable quote was provided quickly and his response to our many revisions was also quick. We decided to choose Sobol in part because we knew that as a smaller business with almost no marketing and no "Customer Service Department" their survival depended on word of mouth and good reviews. Still, it seemed like a risky decision at the time because for all we knew, Sobol could close shop any minute in comparison to larger companies. However, we felt that Archiel had been very responsive and would be personally accountable for our satisfaction and we were right. Sobol was able to work with the window manufacturer to deliver and schedule the install in a very tight timeline.
Installation - Sobol's crew was on-time, courteous, and patient with my many questions while trying to do their work. I have to admit I felt bad for them during the install. It was a cold 2 days, the age of the house made for some unexpected difficulties, and I watched them like a hawk. I was impressed that while they worked quickly they were not in a rush to simply finish and leave. It was obvious to me that they take pride in the quality of their work. The installation, trim and aluminum exterior capping all exceeded my expectations.
Post-sale - Archiel came to our house the day after the install to inspect each window and door to ensure that it was up to his standard and took the time to go through the operation and maintenance recommendations.
In summary, we could not possibly be happier with our choice of Sobol Inc for this project. I would gladly be a reference for any homeowner looking to hire Sobol that wished to ask me questions about the entire experience.
