This is quite a common problem and doesn't necessarily mean that your carpet is or was defective or fitted badly. It could have been caused by numerous things, like heavy furniture being dragged over it, or not being cleaned correctly, or just the fact it has softened up. This means it will need restretching or it will become worse. We can restretch your carpets and save you replacing it and aiding landfill. We also offer a patching (infill) service, damage or burns in carpets repaired, perhaps you have removed a unit or wardrobe and need to replace the carpet, (we will of course need some of the original carpet to patch it) we can also do small fitting jobs like bedrooms and bathrooms etc, and can supply underlay and gripperods.
