While it is possible to install carpet yourself, it is a challenging DIY project that requires precise measurement, proper cutting skills, and knowledge of correct installation techniques. The process involves multiple steps, including removing old flooring, installing underlayment and tack strips, and stretching the carpet to prevent wrinkles, which can take several days to complete.

Before starting, consider these factors:

• Warranty: Many manufacturers' warranties are voided if the carpet is not installed by a professional.

• Tools: You will need to buy or rent specialized equipment like a knee kicker, carpet stretcher, and seam roller.

• Complexity: DIY installation is most suitable for simple, straightforward rooms. Projects involving stairs or floor vents are significantly more difficult.

• Cost: While you can save on labor, the cost of tools plus the risk of expensive mistakes—which may require re-installation—can make hiring a professional more cost-effective in the long run.

Given the potential for errors, voided warranties, and the need for special tools, hiring a local carpet installer is often recommended to ensure the job is done correctly and safely.

The type of flooring you choose for your bedroom comes down to personal preference. Many people prefer carpet over hard-surface flooring types (such as hardwood, tile, or stone) in their bedrooms because it’s warmer and cozier. Carpeting also helps muffle sound, which may benefit those who have trouble sleeping.

On the other hand, some folks prefer the look of hardwood over carpet. People with allergies might also opt for non-carpeted flooring since carpet fibers can attract dust, dander, and other allergens.

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.

The cost to put wooden flooring in an attic can run a wide range. Carpeting can cost as little as $1 per square foot, or even less if you opt for unfinished flooring types like rubber or painted plywood. On the high end, hardwood floors might cost as much as $45 dollars per square foot. For a previously unused space, you’ll probably need to add a subfloor which usually costs about $5 per square foot.
