What homeowners say
The owner came over after the job was completed and asked me to send a revised review. I’m glad to help him. His work was excellent and we discussed how to improve his scheduling.
Chris QuirinA window which has been fixed by Prestige 2 years ago, would not stay opened. Within a few days Andrey came, and made an adjustment, without a charge. The problem was fixed.
Anne PuliaficoGreat experience! They were extremely responsive and came out very quickly. I explained the urgency of getting my window replaced, and he showed up with his team and took care of everything right away. The job was completed before I even finished a work call! Fast, professional, and reliable. Highly recommended, and I would definitely call them again.
