I wouldn’t call them the best company. No!!! They are the best of the best in the entire country! I work in Construction QA/QC industry and they exceeded all the quality and performance measures not limited to detailed quotes, on time delivery & installation, product design (they produce the windows not just dealers), quality of products, quality installation, and price! The best description of this company is UPOD (Under- Promis, Over-Deliver) type of company. My appointment handled by Alex Merkin—this guy is gold. He advises you what works best for you. I can’t thank him enough for his honesty and the on-site follow up to ensure the work exceeded my expectations! Alex is a great estimator and Project Manager! The other who i should thank here is the installation manager Andre and his professional team! In 2 days they finished changing all windows of 4000 sf house from brick to brick and install sidings for 3 bay windows in addition to other works and window trims from inside. Andre and his team they don’t just finish a work, they deliver a piece of are work... TRUST me on that! They know what to do and very organized so they don’t waste time. I was so blessed by working with this company, Alex, and Andre and his team.
