Introduction
Laminate flooring is one of the most popular DIY flooring installation projects available to homeowners, and for good reason. Modern laminate products are attractive, durable, affordable, and designed specifically for straightforward DIY installation using a click-lock system that requires no adhesive or nails. A motivated homeowner with basic tools can install laminate flooring in a medium-sized room in a single day, achieving a result that is visually indistinguishable from a professional installation.
Laminate flooring has evolved dramatically since its introduction in the 1980s. Early laminate was characterised by obviously artificial patterns and hollow, plastic-sounding footfall. Today’s premium laminate products feature high-definition photographic layers that closely replicate the appearance of hardwood, stone, and tile, with realistic embossed textures that add tactile authenticity. Waterproof or water-resistant laminate cores have addressed one of the product’s historical weaknesses, making it suitable for installation in kitchens, bathrooms, and basements where traditional laminate would have been risky.
This step-by-step guide covers the complete process of laminate flooring installation — from choosing the right product and preparing the subfloor through laying the planks, cutting around obstacles, installing transitions, and adding finishing touches. Follow these instructions carefully and you will have a beautifully installed floor that will look great and perform reliably for 15 to 25 years.
Choosing the Right Laminate Flooring
Laminate flooring is sold in planks that typically range from 5 to 9 inches wide and 48 to 60 inches long, with thickness ranging from 6mm to 12mm. Thicker planks (10 to 12mm) feel more substantial underfoot, are more resistant to denting and damage, and produce a quieter, more solid sound when walked on. They also accommodate minor subfloor imperfections better than thin planks. If budget allows, choose 10mm or thicker for the best overall performance and appearance.
The wear layer — the clear protective coating over the photographic layer — determines the floor’s resistance to scratching, denting, and fading. Wear layers are rated by an AC (Abrasion Criteria) rating system from AC1 to AC5. For residential use, AC3 is the minimum recommended rating; AC4 and AC5 offer additional protection and are worth the modest extra cost for high-traffic areas. Check the warranty too — longer warranties (25 years or more) from reputable manufacturers typically indicate higher-quality products.
For kitchens, bathrooms, laundry rooms, or any area with significant moisture risk, look specifically for waterproof laminate or water-resistant laminate with sealed edges and joints. Traditional laminate uses a high-density fibreboard (HDF) core that swells when exposed to prolonged moisture — a serious failure mode in wet environments. Waterproof laminate uses a WPC (wood plastic composite) or SPC (stone plastic composite) core that is genuinely impervious to water, making it suitable for any room in the home. The modest price premium for waterproof products is well worth it for peace of mind.
Subfloor Preparation: The Critical First Step
Subfloor preparation is the most important phase of laminate flooring installation, and the one most often rushed by DIYers eager to see the new floor going down. Laminate flooring requires a subfloor that is clean, flat, dry, and structurally sound. Imperfections in the subfloor will telegraph through the laminate and cause premature wear, clicking noises, and in severe cases, structural failure of the click joints.
The flatness requirement for laminate installation is typically 3/16 inch over a 10-foot span or 1/8 inch over a 6-foot span — check your product’s specifications. Check your subfloor with a long straightedge or level. High spots should be ground or sanded down; low spots should be filled with floor levelling compound, which is applied as a thick paste, levels itself, and cures to a hard surface in 24 hours. Address all squeaks in the subfloor by driving screws through the subfloor into the joists at squeak locations — squeaks will be amplified rather than eliminated by the new flooring.
Most laminate flooring requires an underlayment — a thin foam, rubber, or cork layer installed between the subfloor and the laminate. Underlayment provides cushioning, improves sound insulation, provides a slight level of moisture protection, and helps accommodate minor subfloor irregularities. Many modern laminate products come with an attached underlayment on the back of the planks, in which case additional underlayment is not needed (and adding a second underlayment can actually cause installation problems). A vapour barrier sheet should be installed over concrete subfloors before the underlayment to protect against moisture from below.
Installation Process: Laying the Planks
Acclimate your laminate flooring in the room where it will be installed for 48 to 72 hours before installation. Remove the planks from their boxes and stack them flat in the room, allowing the product to reach equilibrium with the room’s temperature and humidity. This prevents the planks from expanding or contracting after installation, which can cause gaps or buckling. Keep the room at its normal living temperature and humidity during this period.
Plan your layout before beginning installation. The planks should run parallel to the longest wall or the primary direction of light entering the room (along floorboards in the direction of travel is also common). Measure the room width and calculate how many full planks will fit and how wide the last row will be. If the last row would be less than 2 inches wide, adjust the starting point by cutting down the first row slightly to create a wider final row. Snap chalk lines on the subfloor to guide your installation if needed.
Begin in a corner, typically the left rear corner of the room relative to the main entrance. Install the first plank with the tongue side facing the wall, leaving a 1/4-inch expansion gap between the plank and the wall on all sides — this gap accommodates natural expansion of the flooring and will be covered by the baseboard. Place spacers against the wall to maintain this gap consistently. Connect planks end-to-end in the first row by angling the short end of the next plank and clicking it into place. Begin the second row with a cut plank (at least 12 inches long) to offset the end joints, creating a staggered pattern that distributes stress and looks more natural.
Use a pull bar and tapping block to engage stubborn joints fully — never strike directly on the top surface of the plank. Keep rows tight with no visible gaps between planks. For obstacles like door frames, undercut the door casing with a handsaw so the flooring slides underneath rather than trying to cut around it — this creates a much cleaner finished appearance. Use a jigsaw for irregular cuts around pipes, corners, and heating vents.
Frequently Asked Questions About Laminate Flooring Installation
Do I need to remove baseboards to install laminate flooring?
It depends on the design of your baseboards. If there is enough clearance to slide the flooring underneath the existing baseboard (the expansion gap requirements can be met without removing the baseboard), you may be able to install without removal. However, in most cases, removing the baseboard before installation and reinstalling it after produces a cleaner, more professional result. It also makes it easier to maintain the required expansion gap consistently. Use a pry bar carefully to remove baseboards without damage so they can be reinstalled, or plan to replace them as part of the project.
Can laminate flooring be installed over existing flooring?
In some cases yes, but with important conditions. Laminate can be installed over a single layer of hardwood, vinyl, or existing laminate if the existing floor is in good condition, firmly adhered, and flat. Installing over multiple layers of flooring can cause height issues at doorways, transitions, and appliances. Never install over carpet, over flooring with significant height variations, or over flooring that is loose, damaged, or wet. Check the maximum allowable height restrictions for your specific product, and always verify that the combined floor height does not create problems with doors and appliances.
How long does laminate flooring last?
Quality laminate flooring typically lasts 15 to 25 years or more under residential use. The longevity depends on the AC rating of the wear layer, the quality of installation, and how well it is maintained. High-traffic areas may show wear sooner than low-traffic rooms. Unlike hardwood flooring, laminate cannot be refinished when its surface wears — when it reaches the end of its life, it must be replaced. Choosing a higher AC rating for heavily trafficked areas extends the floor’s useful life significantly.
Is laminate flooring slippery?
Smooth, high-gloss laminate can be slippery when wet, which is an important consideration for bathrooms, kitchens, and entryways. Textured or embossed surface finishes provide better traction than smooth, polished surfaces. Some products carry a slip-resistance rating that can be compared when shopping. In areas where spills are likely, ensure the laminate product you choose has an adequate texture for safe use, particularly for households with children, elderly residents, or pets. Area rugs with non-slip backing can also be used to add traction in specific locations.
Can I install laminate in a bathroom?
Yes, if you choose a waterproof laminate product specifically designed for wet environments. Traditional laminate with an HDF core is not suitable for bathrooms because prolonged moisture exposure causes the core to swell and fail. Waterproof laminate with a WPC or SPC core is genuinely impervious to water and can be installed in full bathrooms. Ensure all transitions and edges are properly sealed, and address any potential water infiltration sources (leaking toilet, shower splash zones) to ensure the flooring performs as intended in the long term.
Final Thoughts
Installing laminate flooring is one of the most accessible, high-impact DIY home improvement projects available. With proper preparation, quality materials, and methodical installation technique, a homeowner with moderate DIY skills can install laminate flooring that looks beautiful, performs reliably, and significantly enhances the appearance and value of their home. The key to success is investing adequate time in subfloor preparation, allowing proper acclimatisation, and maintaining the required expansion gaps throughout the installation.
Choose quality materials appropriate for the room’s moisture exposure, follow the manufacturer’s installation instructions carefully, and take your time to ensure each row is properly aligned and fully clicked before moving on. The result will be a floor you are proud of and will enjoy for many years.
