Carpet Installation: Preparation and Implementation Tips


Commercial carpet installation requires planning, attention to detail, and meticulous workmanship. The benefit of such painstaking perfection extends the life of the carpet, promotes a safe environment, and creates an attractive and functional workspace. Being properly prepared and knowing what to expect makes the process seem effortless.    


Commercial carpet installation requires a team effort. Office furniture and equipment must be moved. If applicable, painting and drywall should be completed before carpet installation occurs. All electronics, equipment and computers must be disassembled and moved to ensure their safety during the process. Some equipment must be moved by the manufacturer or warrantees can be voided such as vending machines or copiers.

Interior doors may also need to be temporarily removed to accommodate large rolls of carpet being moved throughout the building. Professional installers should be made aware of any security systems or alarms present in the building and locking up procedures.

Installation Methods

Glue down carpet installation can be done in two ways for commercial application:

  1. Carpet can be glued directly to the floor. When padding is not used, the floor must be very smooth or imperfections could be obvious. The advantage of this method is the carpet will have little to no movement to better accommodate rolling traffic such as wheelchairs or carts. This method is suitable for ramps, flooring transitions and large areas. Some of the drawbacks of this method are the floor is can be less comfortable, less insulated, and durability is compromised.
  2. Double glue down carpet installation glues padding to the floor first then carpet is glued to the padding. Special padding must be used in this process. The advantages are comfort, insulation and extended durability. This method requires additional time to allow the flooring adhesives to cure before traffic can be introduced to the area. Additional cost is a consideration with this method. Additional supplies and eventual removal is more expensive.  

Step by Step

The following is a general outline of the common process for installation methods:

  1. Remove old carpet and padding. New carpet must be installed on a clean surface. Remove moldings, cove bases, and any trim that may hinder carpet removal. Remove carpet by rolling it starting at one end of the room.
  2. Begin with a carpet strip that overlaps the floor area by at least 4 inches (10.2 cm). Measure the room at its longest point and add 4 to 6 inches (10.2 to 15.2 cm) to that measurement. Excess can be removed but not easily added. 
  3. Sometimes the carpet is cut from the topside of the carpet and sometimes it is cut from the backside with a sharp utility knife and straightedge. Make sure you put scrap board underneath if cutting on top of other carpet to protect the underlying surface.
  4. Trim the carpet in each doorway so the edge is centered under the closed door. Finally, install a door edge strip to hide any gaping and transition.

Industrial Standards 

The Carpet and Rug Institute (CRI) provides commercial installers with detailed principles and guidelines for carpet installation. CRI 105 Commercial Installation Standards were created and supported by the industry. In 2015 the CRI updated the 105 standards addressing innovations require new methods for carpet installation specifically planning and subfloor preparation.

This document reviews all aspects of commercial carpet installation including:

  • Storage standards dictate carpets must be kept in a climate-controlled dry space and must be protected from dirt and moisture. Stacking heavy objects upon carpet is prohibited.
  • Handling standards prevent damage and distortion from occurring. Guidelines dictate carpet must not be bent or folded. If this is unavoidable, carpet must be unfolded immediately upon arrival at the installation site.
  • Planning standards require scale drawings determining the type of carpet, quantity, installation method, cushioned backing, adhesives, transition molding and seam locations are required. The planning process must be followed to avoid costly mistakes and wastage. 
  • This document goes into great detail about how to safely and effectively deal with Alkalinity, humidity and ambient temperatures, among other things.
