How to Know If Repair Must Be Done for Carpet Seam


Most houses are going to end up with some seams in their carpet because houses vary too much in size, in construction, and in dimensions of the room. Often times a carpet seam splits apart because it was never sealed properly. When this is the case, one or two rows of carpet will begin to come loose right at the seam.

Split carpet seams can be a problem in both residential and commercial carpet alike. Carpet seam splitting can be caused by improper installation, such as seams that weren’t thoroughly secured and properly aligned. This is especially true with woven or what’s incorrectly called a Berber carpet.Carpet seams also come apart due to poor quality seam tape and adhesives.  The last reason carpet seams split apart is due to age and traffic. If your carpet has been in continuous use for thirty or forty years and the seams are splitting apart, then the carpet has lasted far longer that it was ever designed to last. More common in carpet repair, though, is the need to re-seam a loose carpet as part of the carpet re-stretching process. When we stretch carpet to eliminate ripples, we end up with extra carpet at the edges. If the edge is the edge of the room, we trim off the extra around the periphery; if that edge is at a seam, we cut off the extra carpet at the seam, and then repair the seam.
