Laminate is one of the few flooring projects where a careful DIYer can match a professional install – as long as you nail the prep. This guide keeps things simple and focuses on the decisions that actually affect the finished floor, plus the mistakes that show up six months later if you skip steps.
Laminate is a strong pick if you want a new floor without a big budget hit. It's durable, affordable, and in most cases installs right over your existing floor. Rooms where it works well: living rooms, bedrooms, hallways, home offices and finished basements.
Bathrooms and any area with standing water are a different story – go with waterproof luxury vinyl or tile instead. Kitchens are fine as long as you wipe up spills quickly.
For the project you'll need:
Figure out how many packs you need with the flooring calculator. It accounts for waste, so you won't run short halfway through the room.
Let the unopened packs sit in the room for at least 48 hours. If you skip this, the planks expand or contract after you lay them and you'll end up with gaps or buckled seams.
Place a 6-foot straightedge on the subfloor in random directions. If there's more than 1/8 inch of gap underneath, level those spots with floor leveler. Check that doors can still swing freely – you may need to trim the bottom a bit, since laminate raises the floor height.
Roll the underlay perpendicular to the direction you plan to lay the planks. Butt the seams and tape them – no gaps. If you're over concrete, make sure the underlay has a built-in vapor barrier.
Typically you'll lay planks running toward the main source of light – it makes the room feel bigger. Check where the last row will end up and adjust the first row width so you don't end with a sliver less than 2 inches wide along the far wall.
Place spacers against the wall, then set the first plank with the tongue side facing the wall. Click the next plank in on the end. Cut the final piece to length, and use the offcut to start the second row.
Stagger every row by at least 12 inches so the pattern looks natural. Angle each plank into the long-edge groove and tap it tight with the tapping block. Scribe and cut around doorways, pipes and tight spots as you go.
Once the floor is down, pull the spacers and install baseboards. Nail them into the wall, not the floor – the floor has to be free to expand and contract.
By far the most common mistake is forgetting the expansion gap. Laminate shifts with temperature and humidity, and if the planks touch the wall the floor will buckle up in the middle of the room. Keep that 3/8 inch gap all the way around – including door frames and radiator pipes.
Second: rushing the prep. Lots of DIYers dive straight into laying planks without checking or leveling the subfloor. The result is a floor that creaks and feels spongy a few weeks later. Spend the extra hour up front – it pays off.
Third: hammering directly on a plank. That's a fast way to break the click joint and leave a gap you can't close. Always use a tapping block as a buffer.
Use the flooring calculator to figure out the number of laminate packs based on your square footage and waste. Then build it all into a material list and keep track of spending in the renovation budget.
Installing laminate is one of those projects where 80 % of the outcome depends on prep. Get the subfloor flat, let the planks acclimate, respect the expansion gap, and the finished result will basically take care of itself. A typical 200 sq ft room fits in a long weekend, and most homeowners save $500 to $1,200 doing it themselves.
Keep going with one of these – they pair well with what you just read.
