Honey, I shrunk the carpets: when carpet cleaning goes bad

If you’ve ever hired a carpet cleaning machine in Christchurch or doused your rugs in DIY carpet cleaning solutions, you may have had a rather unpleasant surprise: a carpet that suddenly doesn’t fit the room anymore. Carpet shrinkage isn’t just inconvenient, it’s costly, unsightly, and entirely preventable. So, as we enter the season of spring cleaning, it seems an appropriate time of year to warn you how poor carpet cleaning methods is the prime reason for carpet shrinkage. And that means new underlay and carpets – big avoidable expenses.


Why have my carpets shrunk after cleaning?

Despite many carpets being sold as hard wearing, their fibres are far more delicate than you may think. Certain materials, particularly wool and jute-backed carpets, are highly sensitive to moisture and when oversaturated, the natural fibres swell and distort. As they dry, the tension pulls them inward, leading to visible shrinkage.


Common carpet cleaning mistakes include:


Over-wetting:  whether you’ve hired an inexperienced carpet cleaner or attempted the job yourself with a rental machine, the problem is the same: consumer-grade equipment simply lacks the suction power required for thorough water extraction. As a result, carpets remain too damp for an extended period, increasing the risk of shrinkage, warping, and mould growth.


Improper cleaning products: off-the-shelf supermarket detergents may promise the world in terms of results, but they are rarely designed with the delicate structure of different carpet fibres in mind which can warp them. Using the wrong formula can cause irreversible damage, including fibre weakening, colour bleeding, or discolouration. Worse still, many of these products leave behind a sticky residue that dulls the carpet’s appearance but also attracts dust and dirt so your floors can look dirty again within days of cleaning.


Uneven application: it’s all too easy to oversaturate certain areas while neglecting others. This imbalance leads to patchy textures, rippling, and visible distortions in the carpet’s surface. In severe cases, over-wet sections may shrink or pull away from the backing while drier patches remain unchanged, leaving an uneven, unsightly finish.


Cheap carpet cleaning in Christchurch suddenly becomes expensive when you factor in the risks. Shrunken fibres, stubborn stains that set deeper, and lingering moisture can all lead to permanent damage.
