Engineered Hardwood Installation in Norcross, GA

When you compare engineered flooring samples, it is easy to focus on color and width and overlook the edges. Yet the way planks join each other decides which installation methods are possible, how the floor handles an imperfect subfloor and how easily a board can be replaced years later. For anyone in Norcross weighing engineered hardwood installation, the edge system is worth understanding before choosing a product.

Most engineered planks use one of two profiles: traditional tongue-and-groove or a click-lock system.

Two ways engineered planks join

A tongue-and-groove plank has a tongue milled along one side and end and a matching groove on the other. Rows slide together and are held by fasteners, adhesive or glue in the joint. A click-lock plank has a shaped profile that hooks into its neighbor, usually by angling the long edge in and dropping or folding the end joint down so it locks without glue.

Both systems can produce a handsome floor. The difference lies in what holds the floor in place and which installation methods it allows.

Tongue-and-groove: stapled, glued or edge-glued

Tongue-and-groove engineered planks are the most adaptable. Over plywood they can be stapled through the tongue. Over concrete or wood they can be glued down with a full spread of adhesive. Some products can also float, with a bead of glue run in the groove so the rows join into a single sheet over an underlayment.

That range lets the method follow the subfloor and the moisture readings. The manufacturer’s fastening or adhesive requirements still govern the details: staple type and spacing, the adhesive and trowel, or the specific edge glue for floating.

Click-lock: built for floating

Click-lock engineered floors are designed mainly to float. They go together without fasteners or edge glue, so installation is quicker and cleaner, and the floor can sit over a slab with a vapor retarder or over a wood subfloor with underlayment. Some click products are also approved for full-spread glue-down, which gives a firmer feel.

The locking joint is precise, and it needs support. If the subfloor dips, the joint above it flexes with each step and can eventually loosen or click. That is why substrate flatness gets so much attention on a click floor, together with consistent perimeter expansion space.

How the edge system affects repairs later

If a plank is badly damaged years from now, the repair depends on how the floor was installed. On a floating click floor, rows can sometimes be unlocked from the nearest wall back to the damaged board, though in a large room that means lifting many planks. More often, the damaged board is cut out, the locking lip of the replacement is trimmed and the new piece is glued in.

A stapled or glued tongue-and-groove board is removed by cutting it out in sections and gluing in a replacement. Either way, a few spare planks from the original order make the repair much easier to match.

Doorways, jambs and the last row

Edges affect the details at doors. Door casings are undercut so planks slide beneath them, and a click plank sometimes cannot be angled into place under a jamb; there its locking lip may be trimmed and the joint glued. The last row along a wall is ripped to width and drawn into place with a pull bar, used carefully so the finish is not marked.

Door clearance is checked beforehand, since the underlayment and plank together set the new height. Transition pieces where the floor meets other surfaces are chosen to suit adjoining floor height and the installation method.

Getting the rooms ready for installation day

Before the crew starts, the rooms are cleared of furniture and stored items, and fragile pieces on nearby walls are taken down. Subfloor condition and moisture are confirmed, and the flooring has been delivered and acclimated as the product requires. By then, plank direction, trim, species, finish and plank size should all be settled and written into the estimate, together with any allowances and how changes will be handled.

During the work, finished sections are covered to protect the factory finish. If you are deciding between engineered and solid flooring, our solid hardwood installation page explains how solid tongue-and-groove boards go down.

Questions about click and tongue-and-groove floors

Is click-lock engineered flooring as good as tongue-and-groove?

Neither is better in every case. Click-lock floors install quickly and float well over slabs and many subfloors, but they need a flat surface to keep the joints tight. Tongue-and-groove planks can be stapled, glued or edge-glued and floated, so they adapt to more situations. The right choice depends on your subfloor, the feel you want and the product’s approved methods.

Can click-lock engineered planks be glued down?

Some can. A number of manufacturers approve full-spread glue-down for their click products, which gives a firmer, quieter floor than floating. Others allow floating only. The installation instructions for the specific product say which methods are permitted and which adhesive to use, so check them before assuming either way.

Why do door casings get cut at the bottom during installation?

Undercutting the casing lets the new planks slide underneath it, so the floor ends neatly without visible gaps or thick caulk lines around door frames. It also leaves room for the floor’s expansion space, hidden under the casing instead of exposed. A small jamb saw removes just enough wood to match the combined height of the underlayment and plank.
