Vinyl windows, replacement windows, vinyl siding installation

One of my very good friends moved to a new house in Maryland over the weekend. However, it was only after moving in that she realized that the windows need replacing. Hence, she asked me to quickly find out about any good Replacement Window contractor in Maryland and arrange to have the contractor come over to take a look at the problem and fix it as soon as possible. I told them that I would get on the job pronto, because I know what she must be going through. This is because I had faced a similar situation a few years back when I had moved into my house back then. All of a sudden the Vinyl Windows broke on me, and I had to similarly locate a Vinyl siding installation contractor immediately as well. However, at that time I was not so lucky and was not able to find one for over a week, as there were severe snowstorms going on then. I used to sometimes go sit in my car and turn the heater on to warm myself up. Anyway, I gave her the details of a company that I came to know about through another Maryland friend of mine. That company is located in Maryland and serves the greater tri-state area.
