If you want the job done right and every detail taken into account than you want Crystal Exteriors. My home builder installed an entry door improperly in the opening of my home which allowed in water and air damaging the door frame. Mr. Li came out personally to examine and measure the opening for the new Provia door and took on the task of chopping out the old concrete step and pouring a new one so the door fit properly. All of this done on time and at a reasonable cost. I happily recommend Mr. Li and will be purchasing a new Provia patio door from Crystal Exteriors.
