If you get a second opinion and they can’t be refinished, then your best option will be replace them…or wait until you can replace them. Given when the house was built I’m doubting the floors are even, so putting a floating on top will be a really bad option as they will wobble. And, installing wood on top of thin wood is a really bad solution. If your foundation is weak, your floor will be weak and it will creak and separate.
Like anything, whether you refinish your hardwood floors or replace them depends on your personal circumstances. If you are about to move into a new home, refinishing your hardwood floors is much easier vs. if you already live there. Clearly the cost to refinish the floors Is much less expensive than replacing them (For perspective, to replace them may cost 3-5 times as much). Denver Hardwood Floor Install
Most floors use a tongue-and-groove design for connecting adjacent strips. This design makes replacing a single strip or plank challenging, but not impossible. First, look for any nails in the damaged board and drive them as far through the board as possible by using a hammer and nail set. Carpenters use nail sets to drive nails flush with trim without damaging the trim with a hammer. After you’ve cleared the nails, it’s time to remove the damaged board and install a new one. Follow these steps:
There are some characteristics that are common to each category: solid wood is more frequently site-finished, is always in a plank format, is generally thicker than engineered wood, and is usually installed by nailing. Engineered wood is more frequently pre-finished, has bevelled edges, is very rarely site-finished, and is installed with glue or as a floating installation. 
I love it! I actually have an entire wall dedicated to most of my hand tools. And I want to build a miter station along one wall at some point. I’m tempted to add a bunch of drawers for a clean look and to keep dust travel off of shelves, but I have a serious “out of sight, out of mind” mentality. I think I’m going with shelves and a few drawers as a compromise. Outstanding workmanship!
If your only goal is to brighten your floors and restore their original shine, consider refinishing them. But if you want to change some aspect of the floor itself, like the style of the wood, the direction of the planks or the consistency of the material, you will need to invest in a full replacement. Refinishing is ideal to restore existing wood, while replacement is ideal for establishing a completely new look or feel. Denver Hardwood Floor
– If your floors are REALLY OLD and have been refinished many times, it may be time for a new floor. I’m not talking about oak floors that have been dinged and scratched up…I mean if your floors have been down for over 100 yrs and refinished at least 5 times. If you can see the “tongue” where the boards fit together, it’s probably time for a new floor. Or, if your floors are rather bouncy and/or don’t seem very sturdy, it’s time for a new floor. This happens more often with pine floors as pine floors are softer and used a long time ago. Denver Hardwood Floor Install
Maple is another great choice for hardwood flooring. Many people prefer its light tan look, which blends into home interior spaces. As one of the strongest woods, maple is a top choice for high-traffic areas of a home. The wood doesn’t scuff easily, making it a good choice for homes with children or those with a lot of foot traffic across the floors. Maple requires minimal maintenance, with weekly sweeping and annual applications of wood soap to prolong the life of the floors. Denver Hardwood Floor

Measure rooms one at a time. It’s easiest to measure rectangles, so if you have an “L-shaped” room, divide it into 2 rectangles and measure them separately. The length of the rectangle multiplied by the width equals the square footage. For example, a room, or section of a room, that is 20 feet long and 12 feet wide produces this formula: 20 x 12 = 240 square feet. If the flooring you are purchasing is sold by the yard, divide the square feet by 9. So, 240 square feet / 9 = 26.667 square yards.
We live in a 1924 home with very heavy thick oak woodwork thru out. It also has oak floors, quarter sawn in narrow strips, that In most rooms are in need of refinishing. We had a professional come & take a look yesterday, she said the flooring is too thin to sand & refinish. I was shocked, the floors have never been refinished. I was so disappointed. What can be done, if anything? We also have extended our kitchen & wanted to put oak flooring down to match the rest of the house. She said they don’t make this thickness anymore & the new flooring would be much thicker, therefore making it higher than the dining room that opens to it. Hardwood Floor
– If you want less mess and shorter installation, replacing the floors will usually take less time than refinishing them. Refinishing hardwood floors is messy and time consuming. It’s especially challenging if you are already living in the home and have furniture everywhere. Refinishing you hardwood floors can easily take 4-5 days and during that time you can not have furniture on them nor walk on them. For some homes, this creates logistical nightmares as they can’t stay in the home nor would they want to given the smell and the mess. Alternatively, if you replace the floors with prefinished hardwood, it’s a much faster process, less messy and you can still live in the home fairly easily. I have many customers that have done this simply because they want to avoid the mess created from refinishing the hardwood floors. Denver Hardwood Floor
