Installing wood flooring

But upgrading to hardwood floors is expensive, even if you do it yourself. And the final cost is usually much more than the square-foot price that’s advertised. If you’ve tried to calculate how much wood floors will cost based on the ads in the paper, you’re in for a shock.

Of course, prices vary by region, but if you take a few things into account, you should be able to make an educated guess about how much it will cost to upgrade to wood flooring. Once you have an idea, you’ll know whether it’s worth your time to start shopping or not.

Bear in mind that, unlike carpeting, wood floors will last for generations if properly cared for. So you’ll be amortizing the investment over many years. And many flooring companies offer interest-free financing for 12 months and other payment options. They realize that wood flooring is a big purchase that many customers may want help with.

The square-foot price of the wood is just the start. In addition to that, there are other supplies and labor, which will vary based on how the floor is installed.

Wood flooring supply costs.

If you’re lucky enough to have a wood sub floor, you won’t need anything more but some felt paper and some nails or staples. If you’re having your floor installed, these will usually be included in the price of labor. If you’re doing it yourself, figure around $50 for a box of 7,000 staples and ten cents per square foot for the felt paper.

The cost of renting a stapler or nail gun is usually pretty reasonable.

Those without a wood sub floor will incur some additional expense, especially if the floor is to be floated. An underlayment, which can run from 25 cents to $1.50 per square foot will be needed to cushion and insulate the new flooring.

If you have concrete floors, you’ll probably want to use engineered wood flooring that can be glued down. The cost of glue runs from 50 cents to $1.00 per square foot. To be on the safe side, add $1.00 to the price of the wood. Gluing wood flooring often takes longer than nailing it down, so your labor costs may be higher too.

Moisture protection, which is often needed with concrete floors, can add another $1 to $2 per square foot to the cost.

In addition to the floor boards, you’ll need to buy some trim to finish off the floor. If you want quarter-round molding in the same wood and finish as the flooring, this can run as much as $5 a lineal foot. Because there’s waste, it takes more than you think. Your flooring company can help you calculate how much you’ll need.

Wood flooring labor costs.

The cost to install your floor can vary a lot depending on where you live, who installs the floor, and how difficult or easy your specific situation is. If you’re having a full-service dealer install your wood flooring, figure between $2 – $4 a square foot.

The price should include having the wood delivered to your home and stacked, removing the existing flooring, prepping the sub floor, installing the flooring, installing all the trim, cleaning up, and hauling away all the debris. Most installers will move your furniture out and back in once as part of the installation process.

All in, a good-quality, pre-finished wood floor will probably cost between $8 and $12 per square foot, or about $1,200 – $1,800 for a 12’ x 12’ room installed. Bamboo or laminate wood flooring will cost less. Premium hardwoods like cherry will cost more.

Before making a commitment, make sure everything is spelled out in writing so there are no unpleasant surprises.

Reducing the cost of wood flooring.

Buying the wood and getting it to your home yourself will bring down the price, and paying cash will sometimes save you another 2 or 3%. Using inexpensive pine molding and adhesive or staples from your local home store will bring the cost down even more. And installing it on your own will probably get the price to about $6 or $7 a square foot, depending on the flooring, where you live, and the competition in your area.

Wood flooring isn’t hard to install.  It’s a project most homeowners can tackle with good results.   But since sanding is tricky, and produces a huge amount of dust, it’s probably best to use pre-finished flooring.

Make sure you have the right sub floor for your wood flooring.

Before you decide which kind of wood floors to install, you’ll need to evaluate your sub flooring.  If you have a concrete slab, solid hardwood floors are not an option.  You’ll need to go with an engineered floor.

Solid wood flooring should only be installed over a clean, smooth, level base.  A plywood sub floor will provide insulation and sound proofing for your wood floors.  And give your floors added stability.

Because wood expands and contracts with changes in temperature and humidity, it’s a good idea to store the boards in the room where they’re going for a few days so they can adjust to the new environment.

You should buy about 30% more wood than your measurements indicate because there will likely be some boards that you don’t like and would prefer not to use.

Get your room ready.

If you haven’t already, remove the doors and baseboard molding from the room where you’re installing wood floors.  Numbering the baseboards and corresponding place on the wall will make reinstalling them much easier.

Figure out where the floor joists are and mark their location on the wall with a pencil.  You’ll be installing the wood flooring perpendicular to the joists.

To ensure a smooth surface, go over the sub floor and sink any nails or screws that protrude.  Then use a moisture tester to make sure the room is within the acceptable range.

To minimize creaks and squeaks and add some moisture protection, use a staple gun to tack down a layer of 15-pound asphalt felt.  Overlap the seams by 2 or 3 inches.

Once the felt is installed, measure the width of the room in several places, then snap a chalk line down the center, parallel to the wall where you‘ll start installing the wood strips.  Usually exterior walls are the straightest.

Snap additional chalk lines to show the location of the joists.  Finally, snap a chalk line parallel to your centerline 1/2″ from the starting wall.  Because this gap lets the wood expand, it’s essential.  And after the wood flooring is installed, it will be covered with the baseboards.

Begin installing the wood boards.

Check the boards and discard any that are crooked or warped.  If they aren’t already cut to random lengths, cut them yourself in varying sizes.

Select one of the longest boards and drill pilot holes that match up with the location of the joists.  Using 1-1/2″ finishing nails, nail the board to the plywood sub floor with the tongue side away from the wall.  Place the nails about six inches apart.  Use spacers against the wall to maintain the expansion gap, and to avoid denting the wood, use a nail set to drive the nail slightly below the surface.

If you don’t have a pneumatic blind nailer, you should rent one. It will make the job a lot easier.  Because it takes up some space, you probably won’t be able to start using it until the third or fourth row.

Putting a piece of tape on the head of the nailer will reduce the chance of it damaging the wood flooring.

Once the first board is nailed down, lay out a group of boards, staggering the ends by at least four to six inches.  Cut the end pieces to fit.  This process, called racking, speeds up the job by letting you install large sections of the floor at once.

Place a small piece of scrap next to the second-row board and hit it with a mallet to make sure the tongue and groove fit together tightly.  Then use the blind nailer to drive a nail at an angle from the top of the tongue into the sub flooring.   Driving the nails at an angle keeps them from becoming loose over time.

You should nail the board every ten inches or so, starting about three inches from the end joints.

When you get down to the last two or three rows, you won’t be able to use the blind nailer anymore, and you’ll need to face nail them.  As you did with the first board, drill pilot hotels and attach them with 1-1/2″ finishing nails.  You may need a pry bar to pull the boards together for a tight fit.

Sink the nails with the nail set and then use a matching putty to fill the holes.

Once the wood floor is installed, install the transitions, and reinstall the baseboards.
