The four main ways to install engineered wood flooring — floating, glue-down, nail-down, and staple-down — and how to choose the right one for your subfloor, room, and product.
A practical guide for Toronto homeowners and DIYers choosing the right installation method
Engineered hardwood is one of the most popular floors in Toronto homes because it delivers the look of real wood with better stability — but how well it performs depends heavily on how it's installed. There are four main installation methods, and the right one depends on your subfloor, the room, and the product you've chosen. This guide walks through all four, explains when to use each, and shows how to get a result that lasts.
How to Choose the Right Installation Method
Before you pick a method, three things matter most: your subfloor, the room, and the product.
- Subfloor: Concrete — common in condos and basements — rules out nailing and stapling and points to glue-down or floating. Plywood or OSB above grade suits nail-down and staple-down.
- The room: Basements and condos favour floating or glue-down for moisture stability; main-floor living areas can take any method.
- The product: Click-lock engineered planks are designed to float, while tongue-and-groove boards can be glued, nailed, or stapled.
With those three factors in mind, here are the four methods and when each one is the right call.
1. Floating Floor Installation
This is the most popular method for engineered wood floors, prized for its speed and simplicity. The planks lock together edge-to-edge using their tongue-and-groove or click system and "float" over an underlay — they aren't fastened to the subfloor at all. Some tongue-and-groove products call for a bead of glue in the joint; most modern click floors don't.
Installation steps:
- Start on a clean, flat, dry subfloor and roll out the recommended underlay.
- Use spacers to hold a ¼-inch expansion gap at every wall.
- Lay the first plank in a corner, working left to right, applying tongue-and-groove glue only if the manufacturer specifies it.
- Cut planks to fit at the end of each row, and start the next row with the offcut to stagger the seams for a natural look.
- Keep every joint tight, working across the room.
- Once finished, wait at least 24 hours before moving heavy furniture back.
Best for: condos, basements, and installs over concrete or an existing hard floor. It's the fastest and most DIY-friendly method, and pairs well with an acoustic underlay.
2. Glue-Down Installation
Here the planks are bonded directly to the subfloor with flooring adhesive, giving the most solid, quiet underfoot feel of any method.
Installation steps:
- Set spacers around the perimeter to maintain the expansion gap.
- Spread adhesive in small sections, starting from a corner, using the trowel size the adhesive maker specifies.
- Lay the first row left to right, then tap each following row tight.
- Use offcuts to begin subsequent rows and keep the stagger natural.
- Continue until the floor is covered, then remove spacers and add transition strips and molding.
Best for: concrete subfloors and high-traffic areas where maximum stability matters. Glue-down is also a common choice over radiant heat with an approved product.
3. Nail-Down Installation
A traditional, very secure method for wood subfloors, using a flooring nailer to fasten each board.
Installation steps:
- Set spacers around the room, leaving a ¼-inch gap.
- Lay the first row with the tongue facing the room's centre, pre-drill, and nail it down.
- Countersink the nails and fill the holes with matching wood filler.
- Use offcuts to start following rows and blind-nail through the tongue as you go.
- Continue across the entire floor.
Best for: solid plywood or OSB subfloors above grade. Nail-down is not suitable over concrete, since there's nothing to nail into.
4. Staple-Down Installation
Similar to nail-down but using a pneumatic stapler, offering a strong, fast hold for experienced installers.
Installation steps:
- Start with spacers to set the perimeter and expansion gap.
- Lay the first row, pre-drill, and secure it.
- Drive staples at a 45-degree angle just above the plank's tongue.
- Work row by row until the floor is complete.
Best for: plywood subfloors, much like nail-down. With the right stapler it's quick, though it demands a steady, practised hand to avoid damaging the tongue.
Which Method Suits Your Toronto Home?
Matching the method to your space is what makes the floor last:
- Concrete condo or basement → floating (with acoustic underlay) or glue-down. In condos, the underlay also helps meet building sound ratings — see our condo flooring service for IIC/STC compliance.
- Plywood main floor → nail-down or staple-down for a permanent, solid install.
- Over radiant heat → floating or glue-down with a radiant-approved product; our guide to engineered hardwood and radiant floor heating covers the details.
- Whole-home upgrade → engineered hardwood for your Toronto home explains wide planks, transitions, and finishes.
Why Professional Installation Matters
Engineered hardwood is forgiving, but the details that make a floor last are easy to get wrong. A professional installation includes checking subfloor moisture and flatness, acclimating the wood to your home for 48–72 hours, and maintaining consistent expansion gaps so the floor can move with the seasons. Skipping those steps is what leads to gaps, cupping, or hollow-sounding boards later.
There's a warranty angle too: most manufacturers require their installation guidelines to be followed for the product warranty to stay valid. FloorSure is WSIB-covered, fully insured, and backs every installation with a one-year workmanship warranty. A professional hardwood flooring service gets the method, subfloor prep, and finishing right the first time.
Common Installation Mistakes to Avoid
A few missteps account for most engineered-floor problems, whatever method you use:
- Skipping acclimation. Installing planks straight off the truck invites gaps or cupping as the wood adjusts to your home's humidity. Give it 48–72 hours.
- No moisture test on concrete. Gluing or floating over a damp slab can fail. A moisture reading and the right vapour barrier are essential in basements and condos.
- Too small an expansion gap. Wood expands and contracts with the seasons; a tight perimeter leads to buckling. Keep the ¼-inch gap at every wall.
- An uneven subfloor. High and low spots telegraph through the floor as hollow spots and squeaks. Level and flatten before you start.
- The wrong method for the subfloor. Nailing where you should glue, or floating a product meant to be fastened, undermines the whole installation.
Frequently Asked Questions: Installing Engineered Wood Flooring
Q: Which installation method is best for a concrete subfloor? Glue-down or floating. You can't nail or staple into concrete, so those two methods are the standard choices for condos and basements, often with an acoustic or moisture-control underlay.
Q: Can engineered hardwood be installed in a basement or condo? Yes. Engineered hardwood's stable core handles below-grade and concrete conditions far better than solid wood, which is why it's the go-to choice for basements and condos — usually floated or glued down.
Q: Do I need underlay for a floating floor? Almost always. Underlay cushions the floor, reduces noise, and can add moisture protection. In condos, an acoustic underlay also helps meet the building's sound requirements.
Q: How long before I can walk on or furnish the new floor? Floating floors can usually be walked on right away, but wait about 24 hours before moving heavy furniture. Glue-down floors need the adhesive to cure — follow the manufacturer's timeline before heavy use.
Q: Should I install engineered hardwood myself or hire a professional? Floating floors are the most DIY-friendly. Glue-down, nail-down, and staple-down are more demanding and, done wrong, can void your product warranty. For a large area, stairs, or an unusual subfloor, a professional install protects your investment.
