“I called them up at 10pm because we had a sudden burst pipe in our home. They were there within the hour, the owner assured us that it was going to be great and explained to us exactly what they were doing. They really went above and beyond our expectations. All of our stuff was put back together perfectly, and we were VERY happy with how it all turned out. Definitely our new favorite company.” -Mark G. San Diego, CA

About San Marcos

San Marcos is a city in the northern part of San Diego County surrounded by Escondido, Carlsbad, Encinitas, and Vista. It has a total land area or 24.4 Square Miles. It has a relatively mild weather in May and June, just like the coastal area of San Diego. It can be very warm though during the summer months in view of the Santa Ana Winds, which incidentally can cause wild fires in the area. Usually it rains between November and March, and during the winter months, the temperature hardly goes below freezing point.

It is culturally and ethnically diverse, with Asians, South Americans, even Europeans living with the locals in the area.

It has a host of tourist attractions, in fact the city has been known for having a great selection of restaurants in the Northern Part of San Diego County. These restaurants are mainly concentrated in what is called “The Restaurant Row.” The restaurants in this area have a variety of cuisines.

San Marcos also has some Golf Courses, and is also home to prominent hotels and Inns like the Ramada Inn, the Hamptoon Inn, The Lake House Resort among others. San Marcos is also home to the Double Peak Park which gives its patrons a good glimpse of the Skyline of Downtown San Diego as marked by its Sky Scrapers. The San Bernardino Mountain can also be seen from this vantage point on a clear day.

One can also see some historical houses within the city that are being carefully maintained by the San Marcos Historical Society.

It is also the home of California State University of San Marcos, which is a smaller campus of the California State University System. As of 2010, this particular campus offers 44 undergraduate programs, and 10 graduate programs as well as one program on Doctorate in Education. The campus has three colleges and one nursing school.
