THE REPORT Site Conditions and Geographical Information The carpets in question were installed in town-homes of this multi-unit common-interest development. This facility was located in the southern part of the Canoga Valley in a residential neighborhood. The maintenance and condition of this property was good. The units were all occupied at the time of the inspection. BACKGROUND INFORMATION MADE TO THE INSPECTOR The carpet was installed as the result of a redecorating effort and the spot was noticed immediately after installation. Corrective measures have not been successful and the claimant has not been satisfaction. DESCRIPTION OF PROBLEM AREA BY THIS INSPECTOR The spot was located just inside of the entrance way between the living-room and stairwell. The carpet to the left of the spot was buckled and to the far left was a sliding-glass door. To the right and in close proximity of the spot was a small piece of orange-varnish furniture. The spot had a red hue and changed when viewed from different directions. ON-LOCATION FIELD TESTING A general spotting agent by Groom Industries called Perky SpotterŪ was applied to a towel and the towel was blotted onto the trafficked and spotted areas. The results of this test revealed that the spot did not change. An inspection lamp was used in these two rooms for closer evaluation and to create shadows. This high intensity lamp is equipped with a 200 watt halogen bulb. The spot diminished or disappeared when the light was shone on the spot and it diminished or disappeared. THE ISSUE OF THIS REPORT The question that I have been asked to address is: what has caused the spot? GUIDELINES FOR EVALUATING THE ISSUE Spots can occur when: 1. lighting conditions create shadows on the carpet 2. foreign substances have been split on to the carpet 3. substances from manufacturing or installation wick from underneath the yarn INDUSTRY STANDARDS, PRACTICES & DEFINITIONS The unknown spot is defined by the Flooring Covering Dictionary by the following definition. Spots can be caused by a number of things. If the spot was not present when the carpet was installed, there is a 99 + 1 change that it was caused by spillage, tracking or some local agent. It could be related to something the installer used or product found in the home. Spots do not "appear" for some unknown reason after installation. If they have a pattern, they may be related to the manufacturing of the carpet. If they are randomly spaced, they are caused locally. THE INSPECTOR'S ANALYSIS If a spot is not created from a shadow, then it will become more noticeable under high intensity light. Thus the spot disappears or diminishes when the light is shone on it and in this case the sun light coming from the sliding-glass door reflected off of the orange-varnished furniture and cast a reflection onto the carpet. The ridge in this carpet probably aggravates the problem allowing for a back drop for the reflection. CONCLUSION The spot in question was due to lighting conditions created by reflections from nearby furniture, based upon the light test. |
