The difference between a 40-oz. and 60-oz. carpet is the carpet face weight, meaning the 60-oz. carpet weighs 20 ounces more per square yard.

Yes, laying laminate over carpet may void the warranty of your flooring. Most laminate manufacturers specify installation over a suitable subfloor, not carpet. Deviating from these installation guidelines can invalidate the warranty. You should stick to the manufacturer's instructions to ensure warranty coverage, and you should always consult with professional laminate flooring installers near you if you have any concerns or questions regarding installation methods.

Yes, carpeted stairs are generally considered safer than stairs with hard surfaces like wood, vinyl, or tile. Carpet provides more traction and friction, which helps reduce the chances of slips and falls. Additionally, if a fall does occur, carpet offers more cushioning, which can lessen the severity of an injury. While hard surfaces can look great, they are often more slippery. However, it's worth noting that some carpets, especially if they are new, dirty, or have a slick texture, can also pose a slipping hazard. To improve safety on any type of stair surface, you can add traction treads to increase grip.

Taking carpet off stairs is an easy but multi-step process you can usually do yourself. If you have the right tools, time, and oomph to finish the job, removing carpet from stairs can be an easy-to-medium difficulty task, depending on your stairs, the type of carpet installed, and how willing you are to get your hands dirty. It’s important to review the process, gather the right tools before you begin, and follow a tutorial or directions while you work.
