I've Already Started Installing My Laminate or Vinyl Plank—Now What?!
You came to the right place! Whether this is your very first floor or your third time installing plank, running into a tricky doorway, a stubborn locking joint, an island wrap-around, or a transition question is completely normal. Filter my troubleshooting answers below—or hop into Plank Bootcamp to snap a photo and get direct troubleshooting help from me!
Which Transition Strip (or Stair Nose) Do You Actually Need?
Picking the wrong transition—like putting a T-molding against carpet or a flush-mount stair nose at the top of a floating floor—will cause it to snap or pop loose. Click where your plank is ending below to see my exact pro rule:
Find the Exact Fix for What You're Facing Right Now
How do I install planks around a wall (or island) and reconnect on the other side?
Angled walls, hallways, and kitchen islands are the #1 culprit that throws a floor out of square when you try to wrap around them and reconnect! The secret is snapping a reference chalk line before you split off, and measuring from that reference line to every new row (using The Layout Buddy) so both sides stay dead parallel and meet cleanly on the far side. Inside Plank Bootcamp, I walk you through this exact step on video!
What kind of glue should I use for locking joints that I plane or shave flat?
When you shave the locking ridge off a tongue or groove so a plank can slide horizontally under a tight door jamb:
• For Laminate: Use any quality PVA wood glue.
• For Vinyl Plank (LVP): Use Clear Gorilla Glue (non-foaming)—and be sure to lightly moisten the groove with a damp sponge or terry cloth right before applying the Clear Gorilla Glue! (Glue the planks only to each other, never to the subfloor.)
How do I lock planks together when I have to work backwards into a room or closet?
Planks are designed for the tongue to slide into the groove (working forward). When you have to insert the groove onto the tongue (working backwards), never beat directly on the factory edge! Cut a short scrap piece of plank to lock into the edge, and tap with my one-handed Plank Hammer or pull from the wall end with my 4-lb Plank Puller.
Read My Working Backwards Guide →Where do I start my plank installation so I don't end up with tiny wall slivers?
Always center your layout off the main hallway (for multi-room installs) or the room center (for a single room), check your wall pieces with 10 locked planks and The Layout Buddy, and build rows 2 through 6 anchored with scrap blocks before coming back to install Row 1 at the very end!
See My Multi-Room Starting Guide →Which direction should I run my planks—and does joist direction matter?
I almost always run planks parallel to the walls of the longest hallway because the hall is the visual backbone of the home (and running planks the short way down a narrow hall looks choppy and risks buckling). Because floating floors aren't nailed down like hardwood, joist direction doesn't dictate your layout—unless your wood subfloor has severe high joists under laminate!
Are the refrigerator and stove too heavy to sit on top of a floating floor?
No! I always run laminate and vinyl plank all the way under the refrigerator and the stove. Don't worry about their weight—your floating floor will still expand and contract normally. (Just never install fixed kitchen cabinets or bolted-down islands on top of a floating floor!)
Do I need to install planks all the way under the dishwasher?
You don't have to—though if you're replacing the dishwasher, install the plank under it and run a bead of clear silicone around the perimeter of the cubby. If leaving the dishwasher in place, simply thread its leveling legs up, slide the plank just under the front legs, and lower the legs back down (or end the plank at the legs so the bottom kick-plate hides the edge).
Can the toilet be mounted over the plank, and does the bathroom floor need waterproofing?
Yes! Cut the plank around the toilet flange leaving a 1/4" expansion gap (make sure the toilet flange bolts don't pinch the plank), and set the toilet on top. You don't need special membrane waterproofing under the floor—just use QuietWalk LV (if bare plank) and run a clean bead of clear silicone around the perimeter and toilet base if you're concerned about topical water.
What do I do with all my furniture while installing across multiple rooms?
The goal is to move heavy furniture as few times as possible! Because you can install a multi-room floor in stages once your master hallway line is snapped, shift furniture out of your starting room first, anchor and lay that room, and then roll your furniture onto the newly finished floor (with felt pads underneath!) while you complete the adjoining rooms.
What tools do I actually need to finish my installation without overspending?
Beyond basics you already own (tape measure, utility knife, chalk line, speed square, knee pads, jigsaw, and oscillating multi-tool), the 3 tools that make the biggest difference are The Layout Buddy, The Plank Hammer, and The Plank Puller (plus a small block plane or sharp wood chisel for shaving door-jamb joints).
See My Complete Tools & Supplies List →Can I double-layer foam pad to build up a low spot in the floor?
Never double up foam pad! Doubling foam pad voids your warranty, creates sponge-like flex, and snaps locking joints. If your plank has an attached pad, either put nothing at all underneath it or use QuietWalk LV (the only pad I ever use underneath it—and never use 6-mil poly plastic on concrete!). To shim a minor shallow dip on wood, use layered 30-lb roofing felt (tar paper) or skim with Feather Finish.
I have an uneven floor—should I pour liquid self-leveler or use floor patch?
Avoid liquid self-leveler! Pouring self-leveler requires lath mesh on wood, primer on concrete, spiked shoes, and gauge rakes—and I've seen way too many DIY self-leveler failures crack or debond. Instead, grind down high spots and trowel Ardex Feather Finish (or Henry 549 Feather Finish from Home Depot) into low spots—it bonds to almost anything and never cracks or crunches!
How do I properly install 1/4-inch wood underlayment over a subfloor?
First rule: NEVER use cheap Luan plywood—always use 1/4" Birch underlayment! Remove base trim, undercut all door jambs so the underlayment + plank slide underneath, and use a narrow-crown underlayment stapler shooting 7/8" long staples with a 1/4" crown. Staple every 4 inches in the main field and every 1 inch along all seams!
How hard is it to tear out old flooring—or can I build up the subfloor instead?
Carpet & old floating laminate tear out easily. Single-layer sheet vinyl glued directly to the subfloor is only ~1/16" thick and can often stay down (just feather the edge with Ardex). Tile takes elbow grease and dust protection. If you build up adjoining rooms (e.g., with GoBoard or OSB) instead of tearing out tile, always check first that doors will still clear and that stair heights won't be thrown off!
How do Luxury Vinyl Plank (LVP) and Laminate behave differently during install?
LVP is 100% waterproof, handles unheated cabins, and flexes slightly to conform over minor subfloor waves (though thin LVP can telegraph bumps, and direct hot sunlight can swell it). High-quality Laminate (like Flooret Arista) has a super realistic wood feel and superior scratch resistance, but it hates high floor joists and requires careful moisture protection.
Can I use a flush-mount stair nose at the top of my stairs?
No! A flush-mount stair nose is ONLY for individual stair treads where the planks are glued down and cannot move. Where a floating floor ends at the top landing of a staircase, you must use an overlapping stair nose so the cut edge is covered while allowing the floating floor to expand and contract safely.
How do I finish my plank cleanly where it meets carpet?
Never use a T-molding against carpet—the soft carpet lets the T-molding rock and break! Instead, use a dedicated End Cap (Square Nose) transition, OR if the carpet has plush, long yarns, you can cut the plank cleanly along the carpet (leaving a 1/4" gap from the carpet backing for laminate or 1/8" gap for LVP) and tuck the carpet fibers right over the edge.
Where can I watch step-by-step videos on installing transitions and stairs?
Inside Plank Bootcamp, you get full access to my step-by-step transition videos, doorway undercutting guides, and private community where you can upload a photo of your exact transition or stair landing and get my personal advice!
Read My Flooring Transitions Guide →"Am I Really Capable of Finishing This Plank Installation Myself?"
Yes! I have helped thousands of DIYers—men and women, young adults, middle-aged homeowners, and wise elders—complete their projects with professional results. If you are willing and able to follow the steps I teach, you are capable!
Fear should never stop you. Remember this: God is on your side! He will help you through this and give you the confidence you need—you just have to ask Him. I had no clue what I was doing when I started over 20 years ago, and now I get to teach others how to do it. Pray, my friends—God loves you, and we can all be saved through Jesus Christ!
