How To Fix Gaps On Overcut Laminate, Vinyl Plank (LVP) Engineered Wood Flooring Around Doors | DIY


If you have laminate, vinyl plank, or engineered wood flooring installed around doors, you may notice small gaps or spaces between the flooring and the door jamb. These gaps can be unsightly and can also allow drafts or moisture to enter the room. However, there are several DIY methods you can try to fix these gaps and achieve a seamless look.

One common cause of gaps is improper installation or a lack of expansion gap. The expansion gap is crucial to allow for natural expansion and contraction of the flooring material. If this gap is not present or is not sufficient, the flooring can push against the door jamb and create gaps.


To fix this issue, you will need to create the necessary expansion gap.

To fix gaps on overcut laminate, vinyl plank, or engineered wood flooring, start by removing the baseboard or quarter round molding around the perimeter of the room. Carefully pry it off using a pry bar or putty knife. Once the molding is removed, assess the size and location of the gaps.

If the gaps are small, less than ¼ inch wide, you can fill them with a flexible caulk or silicone sealant. Use a caulking gun to apply the caulk into the gaps, ensuring it is smoothly and evenly distributed.


Wipe off any excess caulk with a damp cloth, and allow it to dry completely before replacing the molding.

For wider gaps, you may need to use a combination of caulk and a filler material. Choose a filler that matches the color and texture of your flooring to achieve a seamless appearance. Wood filler or putty can be suitable for laminate or engineered wood flooring, while vinyl filler or putty can be used for vinyl plank flooring.

Apply the filler into the gaps, using a putty knife or a plastic spatula. Press the filler firmly into the gaps, ensuring it completely fills the space. Smooth the surface of the filler with the putty knife, and wipe off any excess with a damp cloth.


Allow the filler to dry according to the manufacturer's instructions.

Once the caulk or filler is dry, replace the baseboard or quarter round molding by nailing it back into place. Use finishing nails and a hammer or a nail gun for a secure fit. Make sure the molding is aligned correctly and covers the gaps completely.

By following these simple DIY steps, you can easily fix gaps on overcut laminate, vinyl plank, or engineered wood flooring around doors. Not only will this improve the appearance of your flooring, but it will also prevent drafts and moisture from entering the room.
