Replacing a Kitchen Subfloor

Replacing a kitchen subfloor is not quite as complicated as it may sound. The first thing you should remember is that if you are making changes to the design and décor of your kitchen it is probably an excellent idea to check out the condition of your subfloor at some point in the process.

Kitchens and bathrooms are both rooms that present unique problems when it comes to the condition of the sub flooring as a result of the amount of water and moisture that is commonly found in these rooms.

The truth of the matter is that water damage isn’t the only reason for replacing a kitchen subfloor but it is one of the most common. Other reasons for a replacement project would include a bad slope, squeaks in the floors, or soft spots.

Sometimes the smaller problems can be corrected by simply nailing the subfloor into the joists. There is no guarantee however that this will work and if it doesn’t and the problem proves bothersome to you as a homeowner you might seriously wish to consider replacing the sub flooring in order to remove the squeaks or any unevenness in your floors.

What comes first?

When it comes to replacing a kitchen subfloor the first thing you must do is remove the existing flooring. Once this is done you should also take great care that you check the floor joists, particularly in cases where there was water damage, for possible weak points that may need to be repaired or replaced.

You should also check to see if there are any local codes about the type and depth of subflooring or materials and methods that should be used when replacing a kitchen subfloor. Some areas have very specific requirements.

Once you are armed with knowledge it is time to gather your gear and materials. You should take great care that you are using actual subfloor material and not OSB or standard plywood—you should also make sure that the subfloor material that you select is in accordance with your local building codes.

Tools Required

Once you have your materials, tools, and supplies (some of the things you will need include: a chalk line, circular saw, screw gun, tape measure, and deck screws) you are ready to begin.

A cardinal rule when it comes to this particular type of work is that you should measure twice in order to cut only once. These are words to live by with cheap material, as you will be in the habit with working with more expensive material, not to mention the time it will save you. The next step is to measure and cut the length of your subfloor material if the joists aren’t properly located for to use without cutting. You should take care not to measure from the tongue but from the top edge.

The Actual Installation

Once you’ve gotten the measurements and a layout for your floor you can begin the act of actually replacing a kitchen subfloor. You’ve probably noticed that there is tongue and grove set up for the subfloor material.

When you’ve fastened your first piece you will want to make sure that you have popped the second piece into its proper place leaving about an eighth of an inch in order to allow room for the wood to expand. You should check your local codes about the placement of screws but a good rule of thumb is 6 to 8 inches apart.

While this isn’t the most complicated of home improvement projects it helps if you have the basics of safety down at the very least. Replacing a kitchen subfloor is a good project for practicing basic skills.
