How To Fill The Gaps Between Cabinets And The Floor

Cabinets for the kitchen are a great way to give the space personality and flair. However, gaps can be very distracting. Perhaps you are curious about the best method to fill gaps between cabinets and the floor. We have researched this extensively and identified several solutions for bridging these gaps.

The size of the space you need to fill and your reason for sealing the gaps under the kitchen cabinets will determine the method you use. The most effective methods of concealing the area beneath your cabinets are:

• Cover up with caulk or wood filler
• Embellish the top cabinets by installing trims
• Place a toe kick under the bottom cabinets, or swap out the old one
• Use spray foam to seal off an air leak
• Utilize a backer rod to seal off any significant gaps

Fixing the spaces below your kitchen cabinets can be done in a number of different ways. Read on and we will explain everything in greater depth.

Fixing Gaps Underneath Cabinets

There may be some space between your cabinets, and while this is not uncommon, it is something you may want to fix. As an added bonus, sealing the gaps will prevent pests from entering your cabinets and will keep the cold air out of your kitchen.

First, verify that the screws are securely fastened if you notice gaps under your upper cabinets. Occasionally the gaps can be filled by simply tightening the screws.

Using Caulk or Wood Filler for Small Gaps

Caulk can be used to seal not only cabinet gaps but also any other openings around the house. Before applying caulk, wipe down the surface with a moist cloth to remove any dirt or dust. Apply the caulk after the area is dry, beginning at one corner and working your way to the opposite end. When smoothing, use your finger or a little spatula.

Using Wood Filler Underneath Cabinets

Wood filler can be used to bridge the gap between the base cabinets and the toe kick, or the lower cabinets and the trim. Experts recommend using wood filler rather than caulk to provide a more seamless look between freshly painted trim and cabinets.

The many color options available make wood filler an excellent alternative for bridging gaps between trim and cabinets. A wood filler that may be tinted to match your cabinetry is another option.

Adding Trim to Upper Cabinets

To further conceal the gap, trim work can be installed on the base of the cabinets. Skirting can be attached to the ground immediately in front of the door. Back up the cabinet and align the underside of its back to the wall to hide the space.

A decent starting point is with a trim strip. There are peel-and-stick types, so they are easy to apply, and can fill gaps as small as a quarter inch.

Using Spray Foam to Stop a Draft

Spray foam can be used to insulate the space behind the toe kick to prevent the draft from entering the space. We advise hiding spray foam behind the trim instead of utilizing it to fill obvious cracks and gaps.

Wear protective eyewear and gloves when working with spray foam and do as directed on the label. Do not apply the finishing touches until the product has dried completely.
