    Cornerstone recently provided a full house cleaning service in advance of a visit from a relative highly allergic to animals (I have a dog in boarding during their visit). The team of 3 (Gloria, Nilda, Jason) were all prompt, focused and thorough. I would highly recommend Cornerstone for cleaning.

    Ive had Cornerstone out to my house a few times. They are a great company. Truly, each person I have come in contact has treated me the way I would like to be treated. Ontop of that they're knowledgeable and diligent. Today Josh, the electrician was at my house. He was here to help with my thermostat. Josh went above and way beyond anything I could have asked for.

    Cornerstone that’s fantastic! I highly recommend them. I had a generator plug installed so I can hook a portable generator to run the house in the case of an emergency. They came on time, completed the job, trained me how to do everything and watched over me as I did it.
