This is a type of project I have worked on many, many times over the years.Many homes have hardwoods in part of the house but they cut off where they meet carpet,tile or linoleum.By tearing out the carpet,linoleum,etc.... and connecting new wood to the old a more open feel can be created for the house.
In most homes the subfloor is consistent throughout the home.So the carpet,linoleum,tile,etc.. is simply torn out and the new hardwood is added right over the existing subfloor.
Here you see a living room in the process of having the carpet torn out.............
After the new wood has been installed...........
And finally after both the new and old wood has been sanded and finished...........
One thing I look out for on these projects is to be sure to get as good a match between the old and new wood as possible.I have seen too many floors over the years where the new wood was not properly matched to the old.....and it shows!
Its not only important to match the species and grade of wood but also to match the mill or at least the region the original wood came from as well.
I have more to post on this subject, so look for more in the future................Thanks for looking!
