Rugs in high traffic lanes, under rocking chairs and subject to gritty sneakers and crepe soled shoes will show wear. Rotate area rugs to lengthen their useful life. Moths hide in the darkened areas under skirted furniture. Their penchant for wool, left unchecked, can result in holes chewed right down to or through a rug’s foundations. So eliminate the wearing of soft soled footwear and vacuum, vacuum, vacuum …but not the fringe.
Repeated movement or adjustments of heavy furniture can distend a rug’s foundation ultimately causing rips and tears at stress points – e.g. the feet of the furniture.
A carpet will absorb water from a flower pot positioned directly upon it. Continuous exposure to moisture causes dry rot wherein cotton and wool fibers become brittle and break. The affected area literally disintegrates. A saucer is not enough to prevent moisture damage. Plants should really not rest on a rug; rather they should be on a “trivet” or planter with air space between plant and rug.
And the threat of water damage looms large in other situations. Beware of storing a rug in a damp basement or near a water heater. Keep an eye out for on leaky radiators. The good news is that all of these maladies are remedied by reweaving but some projects are major undertakings that can be quite costly.
