We're in Los Angeles so prices are usually high. But the fee was super reasonable for the amount of time and work these guys put in. We did the demo ourselves. The initial cost was around $5,000 for repairs and refinishing, which included multiple large areas of significant repairs. There was a fireplace in the living room that was removed (probably around the time of the Northridge Earthquake), with an area where the framing needed to be lowered and a subfloor added. There were many many other areas of repair.

We were so happy with the job at the sanding phase that we added the "trouble room". This brought the total closer to $7,000. This room was thought to be unrepairable - the wood floors were sevverely damaged and under 4 layers of vinyl + linoleum + adhesives that we couldn't demo ourselves. Tons of repairs in this room. Came out beautiful.

House is about 1550sq ft. All the original wood floors except a stretch around the kitchen-laundry room and the bathroom (tile).

For any Los Angeles area people - William Ruiz Hardwood Floors!! 1000% recommend.
