Get matched with top carpet installation pros in San Ramon, CA

In most cases, you do not need to put padding or underlayment under carpet tiles. Unlike traditional carpet, which requires a separate pad, carpet tiles are designed to be installed directly onto a firm subfloor like plywood, concrete, or tile. Many carpet tiles come with a built-in underlay and attach with peel-and-stick adhesive, double-sided carpet tape, or glue. For a more comfortable, cushioned feel, especially in residential settings, you can opt for padded carpet tiles that have a thicker underlay attached. While it's generally not recommended to install a separate pad, a compact underlayment might be used in some situations, though this typically requires professional installation. An acoustic underlay may also be considered in commercial spaces or multi-level homes where noise reduction is a priority.

While not always required, experts recommend removing baseboards before removing old carpet and installing a new one. This practice leads to a smoother process and a cleaner, more professional-looking finish. Removing the baseboards allows for a seamless carpet installation without the risk of damaging either the carpet or the trim. It also provides a good opportunity to repaint or stain the baseboards and inspect the underlying wall for any issues. If you prefer a quicker option, you can carefully cut the old carpet along the edge of the baseboards, but this may result in a less polished installation for the new carpet.

Yes, carpet tiles are easy to install—even if you don’t have much DIY experience. In fact, the simple installation process is one of the main reasons that people choose carpet tiles over traditional carpet. Since carpet tiles come in individual squares, they aren’t as heavy or awkward to install as regular carpet. Plus, you don’t need specialized equipment (like knee kickers or carpet stretchers) when installing carpet tiles.

On average, installing carpet costs between $3 and $11 per square foot, depending on factors like the carpet material, style, and labor rates in your area. Sometimes, installers will include carpet removal in these costs, so if you don’t have any carpet to remove, you can save time and spend less money on labor.
