The only way to stretch a room properly is to use a Power Stretcher. ‘Getting by’ with a knee kicker is analogous to using a hand sander instead of a floor sander for sanding floors. The knee kicker performs a function of carpet stretching that the larger power stretcher does not do and vice-versa. Carpet stretchers are not just for installing new carpet. If you’ve got old, wrinkled, and bubbled-up carpet, we we can smooth down and “revive” your carpet, extending its life by a few years.
