Yes, flooring should go under the fridge and your other large appliances. Installing it underneath creates a seamless appearance and makes it easier to move appliances for cleaning or replacement. It is also essential for protecting your subfloor. A kitchen contractor will help you find suitable flooring that is durable enough to handle the weight of your fridge without denting or cracking.

Common problems with laminate flooring include surface-level scratches, dents, warping, and separating seams. Scratches can be caused by dragging heavy items like furniture or from not using a mat under rolling office chairs. Dents can occur from regular wear and tear or from dropping heavy objects on the floor. Most of these issues can be prevented with regular cleaning and moisture control, and many are fairly easy to fix for a beginner DIYer.

No subflooring is perfectly level, but you should never ignore any noticeable floor sagging. Most contractors deem a floor that slopes by a 1/2 inch to 1 inch per 20 feet of floor acceptable. Further investigation is required when the slope or sag is more than one and a half inches.

There are a few different types of finishes to choose from for the final step of the project. 

Water-based polyurethane sealants emit fewer odors and fumes but dry quickly, which can pose a challenge when trying to get a smooth coat. Oil-based polyurethane sealants let out more odors and fumes into the air (it’s especially important to wear a respirator if you choose this type), but they take longer to dry, which can be more forgiving during the finishing step. 

Some may prefer wood oil to polyurethane because rather than creating a layer, it becomes part of the wood. Wood oil takes longer to dry, and is less resistant to wear and tear; however, it creates a natural-looking result by enhancing the grain of the wood.
