The vertical deflection exhibited here is caused by the installation of the floor over an insufficiently smooth subfloor, and this is the responsibility of the installer. This report is based on information available to the inspector at the time of the inspection as well as its review and finalization as prepared by the Inspect Solutions’ review team. The observations and conclusion are made to a reasonable degree of certainty. Inspect Solutions reserves the right to add to and/or to modify these findings should additional information become available. Supplemental: Observations / Tests: Product is a laminate plank installed continuously in the living room and dining room on the 2nd floor, and continuously in the hall, master bedroom, 2nd bedroom, and 3rd bedroom on the 3rd floor. Customer complained of vertical movement in planks, chipping, popping, and softness in the floor. Product was installed in August of 2009, and the customer noticed the concerns when she moved in September of 2009. The builder was notified at the time of walk-through. Some repairs have been made to the subfloor as well as to the laminate itself, and 2 of the upstairs bedrooms have been completely replaced. According to the consumer, it is unknown if the product was acclimated prior to its installation, and it is unknown if the HVAC was operational before, during, or immediately after installation. The HVAC has been operational since the consumer moved in. Product is installed over an unknown underlayment of ¾” oriented strand board over engineered “I” joists set 24” on center. It is unknown if moisture tests were taken prior to installation, but the sub floor was leveled, according to the consumer. There is 1 adult in the household. Pets include 1 cat. Customer cleans the floor with Bruce Laminate Floor Cleaner on a regular basis. Inspection revealed lifted corners and edges occurring in several places both on the 2nd and 3rd floors. These lifted corners and edges are generally about 1/32” higher than the adjoining plank, and they can be pushed down flush by hand. Some slight end joint peaking was observed throughout the installation, particularly in the hallway on the 3rd floor. Noticeable vertical movement and “softness of the sub floor’ were also observed in several places throughout including at the edge of the steps in the hallway on the 3rd floor and where the living room meets the stairs to the 1st floor. Close inspection of the smoothness of the floor showed it is out of plane by as much as ¼” in 6’. A moisture test of the product with a Protimeter MMS+ meter showed low moisture content with readings of 115 to 128. A moisture test of the sub floor where it is exposed at the top of the stairs on the 3rd floor showed moisture content of 11.1%. Inspection of the sub floor in this area showed it is cracked and damaged. Inspection throughout showed no evidence of moisture damage, joint swelling, etc. Close inspection showed adequate expansion space throughout. The total uninterrupted distances are 37’ lengthwise by 17’ widthwise. T-moldings have been used between the 3rd floor bedrooms and hallway, but no T-moldings have been used between the living room and dining room. The end joint stagger is generally 5-6” with the exception of a few places with an end joint stagger of 1” in the upstairs bedrooms. Temperature at the time of inspection was 73 degrees with relative humidity of 51.6%.
