When the alarm guy finally showed up to hook up the detectors in the new addition I was glad as I was very anxious to get security system hooked up. I had waited several days for him. I was not too happy when he left, however, as he tracked what looked like tar on the new carpeting. I called the professionals from Alameda Carpet Cleaning and, unlike the alarm guy; they arrived in a couple of hours and left my carpet fresh and looking like new. I was so overjoyed I had them return to clean the carpeting in the entire house.
