It is difficult to compare solid wood flooring to engineered wood flooring due to the wide range of quality in both product categories, particularly engineered. Solid wood has some limitations. Recommended maximum widths and lengths are typically 5" / 127mm wide and 7' / 2100mm long. Solid hardwood is also more prone to "gapping" (excessive space between planks), "crowning" (convex curving upwards when humidity increases) and "cupping" (a concave or "dished" appearance of the plank, with the height of the plank along its longer edges being higher than the centre) with increased plank size. Solid wood cannot be used with underfloor radiant heating. However extra care is necessary with the planning and installation of the heating system and the wood flooring, such as limiting the temperature to 85 °F (29 °C), avoid sharp temperature fluctuations, utilizing an outdoor thermostat to anticipate heating demands, and monitoring the moisture content for the subfloor before installation.
My advice is to bring in a professional to make sure the floors can be refinished (i.e. if there is still enough room/if you didn’t permanently damage the wood), and if so, have them refinish them rather than replace them – that will be much less expensive. I don’t know where you live and the going rates, but in our area, it’s prob. the price is prob. $1-2 lower…but that may be par for your area. Call in 2-3 people to see. I would check Angie’s List (angieslist.com) for some good local people in your area. Denver Hardwood Floor
Hardwood species used in flooring are given a hardwood hardness rating, which indicates how resistant the wood is to dents and wear. This rating is based off a test called the Janka Hardness Test, and it measures the force needed to press a steel ball into the wood sample. The highest possible score on this test is a little over 5,000, with most traditional solid wood floors scoring in the 1,000-2,000 range. The superior density of Rigid Core flooring would exceed the limitations of the Janka test, and instead a higher impact testing is needed to measure real world performance. Here is how the general hardness of plank flooring ranks:
When it comes to choosing the perfect flooring for a home, hardwood is often the first choice for many homeowners. While it is far from the cheapest option on the market, with the average homeowner spending about $4,396 to install wood floors, it’s popular for its classic and warm appearance, durability and versatility. They can add value to your home when it comes time to sell, and this material can make any space look more appealing.
Glue down engineered hardwood, alternatively. If you don't want to nail down the boards, you do have the option of using adhesive to put engineered hardwood in place. It's a good choice, but won't last as long or be as sturdy as nailed down hardwood. The procedure is very similar to the nail-down process. Follow the adhesive manufacturer's instructions for installation and drying times. Hardwood Floor
