The piece between two types of flooring is called a transition strip or transition molding. Its purpose is to cover expansion gaps, prevent tripping, and provide a smooth, aesthetic finish as you move from one room to another.
A transition strip is a small trim piece that connects two flooring surfaces. You'll typically see it: Between LVP and carpet. Between laminate and tile.
Transitioning between two different floors usually happens inside a doorway and depends on height. For even floors, use a T-molding or flat saddle transition. For uneven floors, use a sloped reducer strip or a ramp to safely bridge the gap and prevent tripping.
Floor transition strips provide a clean, finished connection between flooring surfaces. They cover the required expansion gap around floating floors such as vinyl, laminate, hardwood, marmoleum, and cork, while seamlessly joining different materials or ending a floor neatly at walls, fireplaces, and exterior doors.
You don't always need transition strips, but when you do, skipping them can lead to floor damage, buckling, or lost warranties. If your layout includes vinyl, tile, or a combination of materials, use them where necessary.
Common problems with transition strips include tripping hazards due to poor fit, lifting from the subfloor, warping, and failure to allow for flooring expansion, resulting in buckling. These issues often occur due to incorrect installation, such as using the wrong adhesive or failing to account for high-traffic wear.
Apply one, long, steady bead of Loctite® PL PREMIUM MAX to both the T-strip and the floor. Loctite® PL PREMIUM MAX works on wood, laminate, drywall, concrete, brick, masonry, stone, marble, metal, stainless steel, fiberglass and more. It's Omar's go-to adhesive for quick fixes he wants to last - like loose T-strips.
If you want to skip traditional bulky transition strips, try a flush seam binder, caulking, or a custom floor cutout. The best alternative depends on whether your floors are at the same height or slightly uneven.
A mezzanine floor is an intermediate floor between main floors of a building, and therefore typically not counted among the overall floors of a building. Often, a mezzanine is low-ceilinged and projects in the form of a balcony.
The average cost to install transition strips ranges from $25 to $40 for DIY supplies, while professional installation typically costs between $150 and $400 per threshold. The final price largely depends on the material, height difference, and the total labor required.
Joining floors of different levels depends primarily on the size of the height gap. For slight differences up to 1 cm (or ≈38 in), use a carpet reducer or T-molding. For drastic drops, like a step down into a room, build a sloped, custom ramp or install a flush transition strip.
Types of Transition Strips
Some Common Mistakes When Laying Laminate Flooring
Transition strips are nailed into, or glued directly on the subfloor. They hide gaps between flooring transitions and create smooth height changes between different flooring types.
Floor dividers are commonly called transition strips or transition molding. They are used to bridge the gap between two different flooring materials (such as carpet and tile) or to create a safe, finished seam.
Materials almost always classified as flooring include carpet, laminate, tile and vinyl. The selection of floor finishes is very important.
This space, often referred to as the interstitial space or floor-to-floor space, is not just a void; it plays a vital role in the building's structural integrity and functionality.
Reducer and Threshold: A reducer and threshold are types of transition strips that are used to transition between two floors of different heights. Both are available in a variety of heights to accommodate different types of flooring.
Transitioning between two different wood floors depends on their height and layout. For flush floors, use a T-Molding, which rests between them to cover the gap. For uneven heights, use a Reducer to slope gradually. Alternatively, “lace” the boards for a seamless, continuous look.
A transition piece is essential where different flooring options meet in high-traffic areas, as it safeguards the exposed edges from wear and tear. This protection also benefits areas with lower foot traffic.
Fixing a loose or broken floor transition strip usually takes just a few steps: remove the old strip, clean the seam, apply heavy-duty construction adhesive, and press the strip firmly into place while weighing it down overnight.
Glue-down vinyl plank flooring requires a perfectly smooth subfloor, as even tiny imperfections show through. The installation is messy, labor-intensive, and difficult to repair or remove. The required professional labor and adhesive significantly increase upfront costs compared to click-lock alternatives.
Option 2: Meet With Transition Strip
While the floor transition strips don't adjust for height, they provide a smooth shift from one flooring to the next. If you're transitioning from one hardwood to another, you could also opt for a seam binder instead of a transition strip.
