Wood vs. Engineered Wood? No contest in this case. If the home was built in 1905, put real hardwood in. This preserves the integrity of the home's building materials. Plus, as you can see from the age of these floors, higher grades (i.e. thicker) hardwood can be sanded several times; you usually don't get even one chance to sand engineered wood. The hardwood layer at the top of this multilayered product is simply too thin. Level Floors and Subfloors There are ways to level a subfloor, ranging from replacing parts of the subfloor with thicker or thinner sheets of plywood (or planks, see below), to pour-on leveling compounds that harden to make the entire floor level. What you use to level uneven areas depends on what the subflooring is. If it is plywood or concrete, the compound works. But more likely with this home, on floors at or above grade, there will be wood planks laid at a diagonal across the floor joists. So in your home, the layers were probably joists first, then subfloor planks of wood, then hardwood with tongue & groove joints. You cannot effectively use a pour-on leveling compound on a plank subfloor, as there are cracks between the planks. However, you can lay a new hardwood floor directly on a wood plank subfloor as long as those planks are sound and relatively level. Replace individual planks that have been damaged by water or insects, are otherwise compromised, or even missing (it happens!), with either new planks of lumber, or with plywood of the same thickness as the planks. Any lumber you install, for either the subfloor or finished flooring, should be brought in to your home several days prior to installation, so the materials acclimatize to your typical interior temperature and humidity. Unlike for ceramic or porcelain tile, the subfloor does not have to be perfectly level. And unlike vinyl sheeting, planks or tiles, the hardwood won't "telegraph" minor differences in height, and minor surface irregularities, so the subfloor doesn't have to be absolutely perfect; it should be sound, strong, uniform and essentially level. Your flooring contractor can give you specifics on what upgrades your subfloor may need once the original hardwood is removed. Joists If the floor is significantly not level in parts, or if certain areas feel spongy when you walk on them, I recommend you have your flooring contractor, a home inspector, or structural engineer inspect the subflooring and especially the floor joists. You don't want to invest in a new floor, only to have it become damaged because some joists weren't attended to. Transitions Transitions (a.k.a. thresholds or molding) between existing rooms and the new floor ought to be made of the same wood and same finish (stain, polyurethane, etc.) as the new flooring you are putting down. As wood ages, the finish becomes darker, so trying to make the transitions match the finishes of existing floors is very difficult and not recommended (what will match those floors right now won't match later after your transitions age up a bit). Eventually, the transitions wouldn't match either the new or the old floors! Transitions come in four types: reducer (when the two floors being joined are of different heights), seam binder (when the floors are the same height, and the boards from each are very close to one another), T-mold (when the two floors are the same height, but there is a crack between the two rooms' flooring) and stair nose or stair edger (when the flooring needs to curve around the front of a stair's "tread"--the flat part of a stair upon which you tread!). The transitions for your particular project can be ordered when you order the hardwood, so make sure to include measurements for those doorways/entrances. The contractor can tell you if he/she anticipates there will be a height difference or gap between the floorings, which would require those particular transitions. Dry Air Concerns Consult a local lumber supplier or flooring contractor familiar with your local climate conditions to discuss finishes or other tips for keeping your wood floors healthy in the dry winters. Sounds wonderful! Have fun!

Choosing the right flooring type isn't enough for your living condition. You will have to consider the types of cut: flat sawn, rift and quarter sawn, quarter sawn or live sawn. Quarter sawn and rift & quarter sawn will be best choices, because expansion and contraction is along the thickness of the wood. You will need climate control all year round. 70 degrees at 40 % relative humidity is where you want to be throughout the year. The use of a humidifier/dehumidifier will be needed year round. Although, engineered flooring is more stable than solid. Using the wrong wood specie in your living condition can run the risk of de-laminating with engineered wood. If, the top veneer is more or less stable than it's core and backing. You will experience de-laminating in extreme humidity swings. Take in account of what the engineered flooring is constructed of: mdf or plywood. The width of the flooring will account for how much expansion and contracting also. 2 1/4" strips are the most stable. As you go wider, expect to see more wider seasonal gaps. Proper acclimating is critical, should be performed with a moisture meter. For 2 1/4" strip flooring , sub-floor and flooring moisture should be within 4%. For all other widths 2% moisture differentiation is allowed or should not be exceeded. Don't forget proper expansion gaps, which is the thickness of your flooring, example: 3/4" thick = 3/4" gap. Sub-floor type and condition will affect the performance of wood floors. All this needs to be considered for the proper and successful performance of your wood floors.

I'm a fan of Hickory. Love it! I love it's STRONG variation! Yep. Variation is the word that can be used for Hickory. If you are going for "mid-tone" then it means the Hickory is stained. No problem. That's fine. Hickory takes a stain very nicely. But it will still have plenty of variation. The stain will even that out a little bit, but not entirely. The finish is UV cured urethane. I'm not very excited about that finish. If you are going for factory finish, you will want to work with the TOUGHEST finishes on the market (that's why you go with factory finished...for the TOUGH finish). The UV cured urethane is a ho-hum type of finish. Average would be the best way to describe it. The thickness of the plank is 3/4" = normal for sold. The plank width is 5" with random lengths UPTO 60" (5ft). That tells me there will be many planks in the 3' - 4' range. Again, this is ho-hum average. And with a wide plank product, it will need "glue assist". And Hickory certainly needs it because it has a bit more movement (less stable) than white oak. And then there is the "low gloss" format. The low-gloss finish on this depth of colour = nightmare to live with. It will show dust, etc as well as oily foot prints, sock prints, paw prints and will look hazy at certain times during the day. The "haze" is part of the chemical make up of the finish itself = that's how they take away the gloss...they haze it with a chemical additive. The haze goes away when you sand and refinish the floor. That's the only way to fix it. If you must have a mid-tone floor, I would recommend a TOUGHER finish (aluminum oxide or ceramic infused polyurethane) in a satin. Satin is FAR MORE livable. It offers a lovely glow without being shiny. It hides skin oils (like paw prints from dogs) because it is the same gloss level as skin oils....it isn't hazy....you get the idea.

@Sye Phommachanh (or anyone who wants to weigh in) - quick question! we did solid 4" #1 white oak flooring and after samples are doing the following combo for staining: 2 coats Nordic Seal 1 coat Traffic HD We are low traffic, no shoes, no pets, no littles in our house household. Is this combo ok? Another flooring company said we must put Mega One between Nordic Seal and Traffic HD but our flooring person didn't mention this. I want to trust his work but learned it's better to check. They started the process today so appreciate your help on this! THANK YOU!
