It’s winter and wood floors are shrinking. Here’s a question I received the other day about this common complaint.

Need your expert advice please if you can.  I have installed acres of 18mm solid wood flooring in all my rooms. this winter with the heating on it seems to be shrinking. Seems to be taking wooden studding with it, i.e., door frames fixed on top of it have moved too. Will this settle down do you think?  Many thanks in advance.

My answer:

This shrinking is due to the wood losing moisture content. The indoor relative humidity is usually quite low in the wintertime. As the air dries out, it draws moisture from the wood floors and the rest of the wood in the house, studs and doors included. When the weather warms, the relative humidity will go back up and the wood’s moisture content will increase. The wood floors, studs, joists, and doors will swell up again. If the wood was excessively moist when installed, it will never return to the original size. If the wood had the proper moisture content when it was installed, it will return to its original size. It’s impossible for me to say without knowing the condition at the time of installation. (more…)

Do you notice the direction hardwood flooring runs when you walk into a house? It can make a big difference in how it looks and how it behaves over time. Rule number one in laying hardwood flooring is the wood boards should run perpendicular to the floor joists below. This allows the boards to “span” from one joist to the next and be much more solid. If the boards were run parallel to the floor joists, most of the boards would sit only upon the plywood subflooring and not on any of the joists. The plywood is flexible and will “give” fractionally when walked upon. This is a recipe for squeaks and large gaps.

But another rule in laying wood flooring has to do with the aesthetics or look of the flooring. (more…)

I received this question concerning changing the color on existing kitchen cabinets and I thought I would share it with everyone. I get a lot of questions regarding cabinet colors, wood flooring selections and how they should “work together.” The question was:

I have new medium cherry cabinets in a new home that we have just purchased.  I would like them to be much darker.  Is it possible to do this without refinishing the cabinets?  What wood for flooring would you suggest to complement/contrast the darker cherry cabinets?

My answer: (more…)

I’m very pleased to hear that my book, Designing Your Perfect House, is proving to be valuable to people who are building or remodeling. When I wrote it, I really hoped it would become an important resource for people and help them feel more “in control” of the building process. So it heartens me to receive questions like this one concerning the wood floors shown in the book photos.

We are starting to select the different materials around the house.  Your beautiful pictures have been a great inspiration…  I particularly like your wooden floors on pages 114

It’s nearly winter. That means that your hardwood floors are about to show cracks between the boards. If you’ve moved into a new house, these cracks could cause alarm. How could your brand new hardwood floors crack?

Gaps between boards, or cracks, if you will, are not the result of the wood floor failing or falling apart. They are the result of the wood planks shrinking as the relative humidity goes down and the wood floor loses moisture content. The air in the summer has a higher relative humidity than in the summer. This lets the wood flooring absorb moisture and swell. So usually gaps between boards go away in the summer. Then those gaps reappear in the winter as the humidity goes down again. (more…)

    When you mention wood floors to most people, they conjure up an image of a narrow board, red oak floor. But times have changed. Now there are many, many choices of board width and species. And many of these choices come at a modest cost increase. I’ve used white oak, antique chestnut oak, antique heart pine, santos mahogany, jatoba (aka Brazilian cherry), Australian cypress, cumaru, lyptus, and other species you may not have ever heard of. The range of color choices and grain patterns is impressive. (more…)

    If you have wood floors in your kitchen and a natural wood finish on your kitchen cabinets, should the floors and cabinets be the same species of wood and the same color or should they contrast? And if they should contrast, which should be the darker color?

    I often discuss this issue with my clients. My feeling is that there needs to be some color distinction between the flooring and the cabinetry so that the cabinets don’t look like the floor is simply wrapping itself up the walls. After all, one is the floor and the other is essentially furniture and they should express themselves differently. I would suggest that there is no rule about which wood is the lighter or the darker.
