Hardwood Flooring Installation

Robar Flooring provides hardwood floor installation services for clients in Toronto, Mississauga and the GTA.

Before any hardwood floor installation, or laying any hardwood floor it is recommended to let the material become acclimated to the conditions of the house. Ideally, the hardwood flooring should be ordered a few days in advance before the installation and spread in the room in which it is to be laid.

Hardwood floor is laid over a level, clean board or plywood sub-floor. The sub-floor needs to be well inspected. Any dips should be repaired by shimming between the floor joists and the sub-floor. Loose boards should be nailed or replaced, raised edges should be levelled and any openings filled. Over a sub-floor a layer of building paper is laid to make the floor draft-tight. This layer can also help exclude moisture from below and smooth out slight irregularities in the sub-flooring. A plank hardwood floor should not be laid directly on top of a concrete slab. For this kind of hardwood flooring installation a layer of plywood needs to be installed first.

Plank Floor

Plank Floor

Hardwood strips are laid perpendicular to the floor joists or wood sleepers. If an existing board sub-floor has been laid perpendicular to the joist the planks need to be laid across the grain of the strips.

Since hardwood expands and contracts with changes in humidity, a 1/2″ gap is left between the hardwood flooring and the wall around the perimeter of the room. This gap is more critical parallel to the floor boards since wood will expand and contract more across its grain or across the width of the strips.

The first hardwood strip is placed 1/2″ from the wall with the grove edge facing the wall. It is face nailed close enough to the grooved edge so that the nails can be concealed by the base and the quarter-round. All other nails go through the tongue at 45 degree angle every 10 to 12 inches. As the floor is laid, the lengths of planks are selected so that end joints are well staggered and at least 6″ apart from each other. The last strip is face nailed just like the first strip. The expansion gap is covered by baseboard and quarter-round (see diagrams).

Most hardwood floor installations require transition and finishing trims:

Flooring Reducer

Hardwood floor reducer used as a transition from a wood floor to a thinner floor, such as vinyl. Also works to trim out the edge of fireplace or to camouflage a sliding door track. The edge that leads to the lower floor may be either square or rounded. The edge that faces into the room may either overlay the floor or flush with it. (see diagrams).


T-Cap Reducer

This type of reducer is a transition between floors of different heights. One side cover the wood floor, the other covers ceramic tile, laminate wood or other flooring. See diagram.

Stair Nosing

Stairs, though not necessary with prefabricated treads. It is also good for trimming the edges of a floor that sits slightly above another floor.

Is used where floors end in doorways.

Samples of hardwood flooring installation

There are many options and possibilities when it comes to hardwood flooring installation. Few of the most common types include:

  • plank
  • strip
  • parquet
  • engineered
  • laminated floors

All of the above are either nailed or glued down on top of existing sub-floor. In condominiums or commercial properties where sub-floor consists of concrete, plywood is applied on top of the slab in order to allow for nailing of the floor. All glued down floors can be directly applied on top of the concrete. See diagrams below outlining different floor types, installation techniques as well as examples of transition and finishing trims commonly used.
