How to Easily Replace Damaged Wood Subfloors At Your House

How to replace subfloor – One of the most important factors to consider when you want to change the floor at your house is the type of your subfloor. The subfloor has to be strong so that your floor looks at its best. If the subfloor is damaged or poor, the floor at your house cannot last for a long time. This is why you have to know how to replace subfloor if yours is damaged. There are 2 main kinds of a subfloor, which are concrete subfloor and wood subfloor. This article will discuss more how to replace subfloor made from wood materials. Methods of how to replace subfloor are different with how to patch cement floor.

Step 1

The first step of how to substitute subfloor is removing the floor vent by using a screwdriver. Take a look inside and check the cross-section of the existing subfloor in order to decide what kinds of subfloor materials that you need to use. Take a circular saw. Set the blade thickness of the circular saw. If the circular saw has an overlay, include it on the measurement. If you happen do not have any floor vent, set the circular saw blade to cut an inch deep. Once you have done this first step of how to substitute subfloor, you can move to step 2.

Step 2

The next step of how to patch wood floor is drawing a square or rectangular pattern with a straight line at least 6 inches bigger than the damaged subfloor areas. The subfloor has to be supported by some joists. If the cuts are not supported, extend the square or rectangular pattern to the closest seam of joint.

Step 3

Cut through the subfloor or the subfloor and overlay if it exists by following the drawn rectangular or square pattern. Use the circular saw to cut the subfloor. If the area is larger than 36 inches square, divide the pattern in half by cutting it. If the drawn pattern has a curve, use a jigsaw in order to cut the drawn pattern along the curve.

Step 4

The next step is related to wood floor gouge repair. Tap the edge of a pry bar into cracks or seam. Use a hammer to do this. Slightly pry the sections up a little bit in order to make the nails loosened. Take off raised nails or exposed nails by using a claw hammer. If those nails are broken off, hammer the nails down or you can also use a diagonal plier in order to take the nails off. Keep prying up, lifting, and taking off sections and pulling up the exposed nails with the sections.

Step 5

Measure the sides of the cutting areas which are not supported. Use a miter saw in order to cut 2 by 4 studs to the measurement so that additional blocking is added. Use a drill or a driver and 3 inches screws in order to screw the studs flush to the joists’ sides. This way, support is provided for the subfloor.

Step 6

Measure the cutting area and reduce around 1/8 inch from all of the 4 sides. So that there is 1/8 inch space between the new subfloor and the old subfloor. With a circular saw and straightedge, cut the new subfloor and overlay if it is existing. Use the same material kind and also same thickness just like what you have removed. It is purposed to make the existing subfloor and the new subfloor matches. If there is a curved part, cut it in order to fit with the jigsaw. Put the new subfloor in the area of the cutout.

Step 7

With a drill or a driver with 2 inches screws, install the new subfloor to the blocking and joists by screwing it. If it is needed, you are also able to screw the overlay too with 1 ½ inches deck screws. This step is just like squeaky wood floor repair.

Step 8

Draw 24 inches sections tp 26 inches sections in order to replace the subfloor in a complete room. Then, cut the sections with a circular saw. Remove the sections with a pry bar.

Step 9

Put the new subfloor on the joists, centering the tips and joints over the joists, separating the differences so 2 parts are supported by one joint if it is needed. You are also able to add additional blocking if it is necessary. Install the new subfloor to the joists by screwing it with a drill or a driver and 2 inches screws.
