No Joanna, That’s Not Shiplap

By Scott Sidler • April 25, 2016

No Joanna, That's Not ShiplapMy wife and I, like most all old home owners, are fans of a lot of the restoration themed DIY shows these days. Rehab Addict, Barnyard Builders, American Pickers and, of course, Fixer Upper.

Their designs and passion to keep original elements of old houses is so rare in the renovation game that I can’t help but root for them to succeed. I miss the show already!

One of my favorite shows is definitely Fixer Upper. Partly because I’m from Texas, and partly because Joanna and Chip are such a trip to watch. They even have a new book out telling all about their story. Her designs are almost always stunning, but she does have a real addiction to what she calls “shiplap.”

The only problem is that rarely is the wood she calls shiplap actually shiplap! I’ve noticed more of my clients recently asking about shiplap, if their house has it, or can they incorporate it somehow. And I always have to ask “Do you watch Fixer Upper?”

If the answer comes back yes (which it usually does) then my next question is usually, “Do you want actual shiplap or do you just want wood paneling?” This query often brings a cock of the head and a quizzical look. “Aren’t they the same?”

No, Joanna That’s Not Shiplap

Don’t get me wrong Joanna, I love your show and really don’t think you need to change a thing. You do enough for historic preservation that all of us in the field should be grateful.

But, I do want to give you a quick lesson of what shiplap actually is, so that your love affair with the material can continue, unimpeded by any lack of understanding. Don’t think of me as a hater, just a fan who wants to help!

What is NOT Shiplap?

It’s Not Sheathing

This is usually what Joanna calls shiplap and where I start to yell at the TV.

Shiplap is not plain wooden boards nailed on a wall. Often in old houses, these boards can be found on the exterior of the framing just beneath the siding.

Today, we frame a house and then install plywood sheathing to tighten the frame and help square everything up prior to putting on the siding and interior wall coverings. In the days before plywood, we used 1×6 or 1×8 boards, sometimes installed on a diagonal or horizontally as both sheathing and subfloor.

These boards can be salvaged and reused as paneling or other creative design uses since they can add a lot of rich character, but they are not shiplap.

It’s Not Tongue & Groove

Sadly, it’s not this one either. Tongue and groove boards are used in all different places in old homes. Flooring is of course the most common, but there is a lot of siding that is tongue and groove as well.

Tongue and groove (or T&G as it is sometimes simplified) is just what it sounds. One side of the boards has a groove and the other side has a tongue. When they are installed side by side, they fit together nice and snug, which strengthens the floor or siding.

What Is Shiplap?

True shiplap

Shiplap, like tongue and groove, has a special rabbet or notch cut on the edges of the board.  These rabbets allow the boards, when installed horizontally, to self-space themselves and keep water from getting behind them because they fit so perfectly.

Shiplap is mostly found in siding designs because of the need for consistent spacing and water tightness, but it can be found in other places. The lapped joint is one of the simplest you can use to accomplish the spacing and water stopping needs, which is why shiplap was and is so popular.

Once installed, shiplap can look just like regular wood boards because the rabbets are hidden, so yes, it can be hard to tell it apart from regular sheathing boards to the untrained eye, but it is different.

There are various profiles of siding available in shiplap too. Sometimes it’s just flat shiplap boards and other times you can find profiles like Novelty Drop, Dolly Varden, or the poorly named but still attractive #117 lap siding.

For the purist, shiplap is the original flat profile with a rabbet on top and bottom, but I guess if Mrs. Joanna Gaines keeps making us smile with her clever designs and trash talking of Chip, then we can let it slide that she calls a few more things shiplap than actually are shiplap.

As long as she doesn’t start proclaiming that they come from the shiplap tree, I’m still a fan.

Designing With Shiplap

There are so many ways to incorporate shiplap into your home projects and almost all of them are attractive. Whether you use weathered natural wood or want a more clean painted look, a wood covered wall makes any room feel warmer.

Here are some of my favorite designs using shiplap from Houzz to give you a little inspiration for your home.

  1. So, if it’s not shiplap and it’s not T&G, does it have a term other than 1×6 sheathing boards nailed to the inside of stud walls ?

  2. Thank you for the clarification. I was so confused about the tongue and groove vs. old homes interior walls. I certainly appreciate the vocabulary lesson!

  3. We have a master bath that practically matches the cover of a a Sunset Bathroom Remodeling paperback from 1975. Although our “shiplap” or whatever it is, has some water stains close to the floor that make it appear as if there was a flood in the bathroom at some point, it is otherwise in decent shape. We do not have a reason to suspect mildew or mold behind it, even though we do get it regularly on the shower curtain. (The shower surround is all tile, not wood).

    There’s nothing about the feel of this wood that makes it seem waterproofed, although who knows whether it was stained originally. There is a lot of variation in both grain and color, but the variation is evenly distributed enough that it seems natural, not contrived.

    There are LOTS of tiny holes which are obviously left from various owners’ adding and changing shelves, hooks, etc. We see them, but they do not bother us.

    We are interested in lightening up this bathroom and making it feel either more modern (like our furnishings) or more consistent with the actual age of the building, which was built in the 1860s. This is a stone row house on a city street, not a freestanding house. farmhouse.

    The question is, if we clean, stain, or paint this 40+ year old wood, will we be making anything worse? The boards are nicely alternated at the corners so there is a broken pattern of face then end grain then face, so whatever we do will have to work for the end grain as well.
