Minor chips and splinters on floorboards

Q: I have an engineered hardwood floor and the relative humidity in my house is between 45 to 55%. The hardwood is within 2% of the subfloor moisture content. The installation was done by a reputable professional that I personally know and have seen his work over the past few years. The problem is in about 500 total square feet 30 or so boards have gradually exhibited minor chips and splinters, mainly on the edge, but a few in the center. Other than installation error could this be some type of product defect through milling or green wood not being cured properly?

Gaps in glued down floor in high humidity climate

Q: I am buying a house that has old hardwood floors that look great. There is an addition that is newer and the hardwood is installed on a concrete slab. There are some gaps between the boards (the short sides), some as big as about 1/2 inch. The boards are not nailed down due to the concrete. The seller had a guy come out and look at it and he wouldn’t put putty in because he said it would look awful.

Sealer or wax that might hold a splinter in place?

Q: I have maple hardwood flooring in my foyer. One of the boards has a small split and has a small piece that catches on the Swiffer when cleaned. What can I do to prevent this from getting worse? Would be hard to replace a centerpiece about 3″x18″? Any kind of sealer or wax that might hold the splinter in place to prevent it from breaking off?

Cracks at some joints after HVAC was turned on

Q: I had my 225 year old heart pine floors refinished (sanded, caulked and finished with water base satin finish). The job was done two weeks before HVAC was turned on. I now have noticeable cracks at some joints. My contractor says that it is because the HVAC was turned on causing the wood to dry thereby causing cracks. The floors have been in this environment for 25 years. What is your opinion?

Cracks and boards separating after overheating dried out floor

Q: While away from home recently for an extended period of time, a power surge caused our electronic thermostat to malfunction and the heat stayed on continuously for what may have been as long as 2 weeks. Because of that there was extensive damage throughout our home, especially to our hardwood floors which contracted to a point where walking on them without footwear is painful. The cracks are large and the boards have pulled away from the walls.
