Removing old carpet and preparing the subfloor for new flooring is an important part of any flooring replacement project. Properly preparing the subfloor ensures that your new flooring will last for years to come. Follow these steps to remove the carpet and get your subfloor ready for new flooring.

Supplies Needed

Steps to Remove Old Carpet and Prepare Subfloors

1.     Clear the Room

First, remove all furniture and debris from the room. Clearing the space will allow you to work efficiently and safely.

2.     Cut and Remove Carpet

Use a utility knife to cut the carpet into manageable sections, such as 9 ft. by 9 ft. or 12 ft. by 12 ft. sections. Start cutting along the tack strip or carpet grippers around the perimeter of the room. These are the wood or metal strips that hold the carpet in place.

Lift up a corner of the carpet and use a hammer to remove the tack strips. Wear gloves during this process to avoid injuries. The carpet will now be loose on one side of the room.

Next, use a pry bar to lift and remove each carpet section. Roll up the old carpet and immediately dispose of it. Vacuum the subfloor thoroughly once all the carpet and padding have been removed.

3.     Inspect and Repair Subfloor

Examine the subfloor for any damage or flaws. Look for rotten patches, holes, and protruding nails. Use a screwdriver to remove any staples left from the old carpet or tack strips. Hammer down any popping nail heads.

For minor subfloor repairs, use an appropriate wood filler. Allow it to dry completely per the manufacturer’s instructions. Sand the area smoothly before installing new flooring.

If there is extensive subfloor damage, you may need to replace sections of the subfloor. Consult a flooring professional if you are unsure.

4.     Clean Subfloor

Vacuum the subfloor again to remove any debris or dirt. Use a damp mop to wash the floor and let it fully dry before continuing. A clean subfloor allows the new flooring adhesive to bond properly.

5.     Prepare Concrete Subfloors

Concrete subfloors need extra preparation before installing a new carpet. First, use a concrete degreaser to remove any oil or grease spots. Mix it with water per the label instructions and scrub the concrete with a stiff brush. Let the solution sit for 5-10 minutes before rinsing and allowing it to dry.

Next, etch the surface of the concrete with an etching solution. This opens up pores in the concrete for the adhesive to grip onto. Rinse thoroughly and allow the concrete to dry completely, which typically takes 24 hours.

Optionally, apply a latex based concrete primer before installing carpeting over concrete. Check the new carpet manufacturer’s recommendations first. Let the primer dry fully before beginning carpet installation.

6.     Prime Wood Subfloors

For new carpet going over a wood subfloor, apply a layer of latex floor primer. This seals the surface and creates a moisture barrier between the wood and carpet. Apply primer to clean, dry wood with a paint roller. Let it dry fully before laying new carpet padding and flooring.

If your wood subfloor is an older wood plank floor, check for gaps between planks. Narrow gaps under 1/4 inch can be filled with a sander dust and wood glue mixture. Wider gaps require cutting and replacing sections of the wood subfloor before priming.

When Preparing Subfloors, Safety First Work safely by wearing gloves, safety goggles, a dust mask, and knee pads during carpet removal. Work in a well-ventilated area and take breaks often. Be sure to dispose of the old carpet and tack strips properly.

Final Words

With some determination and elbow grease, you can save money by preparing the subfloors yourself before installing beautiful new carpeting. Taking the proper steps when removing an old carpet results in a smooth, clean foundation for lush carpet that will last for many years.
