Lattice was a very common thing on old houses. Not just for flowering backyard trellises, but to protect foundations from critters, varmints and the neighbor’s nosing cat. Just because lattice performs a valuable function keeping your crawl space free of pests doesn’t mean it can’t be a beautiful part of your home’s curb appeal.
Don’t settle for the dirt cheap home store version of lattice. This stuff is so thin and poorly assembled that it rarely lasts more than a couple years. And the plastic stuff that is also available never holds paint once lawn mowing season starts again.
You can make your own historic lattice or have a local carpenter, like my company, make it for you very simply. I’m not saying it doesn’t take time to assemble all the pieces, but it certainly does not require advanced woodworking skills and a shop full of machinery to build your own historic lattice.
In this post, I’ll walk you through some of the details for making simple vertical stick lattice. Other popular historic patterns are checkerboard and diagonal checkerboard, but this one is the easiest to start with.
Step #1 Assemble Your Materials
- Rot Resistant Wood – The main ingredient in quality lattice is quality wood. You need a very rot-resistant wood since this will be installed in contact with the ground. You can find some ideas for good rot-resistant woods here.
- Stainless Fastners – You’ll also need stainless nails and staples. so your lattice doesn’t come apart at the seams. Foundation lattice takes a beating in the weather and you need to use long lasting materials if you want your lattice to last. I use 3/4″ or 1″ stainless steel narrow crown staples and also 1 1/4″ stainless steel brad nails to assemble my lattice.
- Hardware Cloth – To keep the little pests like rats and mice out, you need 1/4″ hardware cloth along the backside of your lattice. Chicken wire isn’t sufficient. A mouse can fit through an opening larger than 1/4″ so you need this small thick gauge wire mesh to do the job right.
- Oil-based Primer – For exterior woodwork this is the only way to go.
- Finish Paint – Pick a high quality acrylic paint to finish the project off.
Step #2 Make Your Cuts
Take your measurements and start making cuts. When you measure, it needs to be a tight fit to keep the critters out, but don’t make it impossibly tight. Remember that you’ve got an old house and not every opening between the foundation piers will be the same or even square. Just because it is 48″ across the top doesn’t mean it will be the same measurement at the bottom. Each panel must be custom.
Your lattice should fit so that the bottom is resting just at or slightly above the dirt. Note the pieces prior to assembly in the photo. You can use whatever size is appropriate to your project. In this case we used western red cedar milled to a 1/2″ thickness, but you can just as easily use 3/4″ (simple 1x) stock available at any lumber yard.
The tops and sides were 4″, the lattice pieces themselves 1 1/2″ and the two bonding strips (laying at the bottom of the photo) were also 1 1/2″.
After you have your measurements, rip all your pieces to width on the table saw. Once everything is the right width, you can start cutting everything to length on the mitre saw.
How many pieces of individual lattice do you need? That depends how you tightly or loosely you want to space your lattice. The primary job of the lattice is to keep larger animals like cats, raccoons and possums from getting in. Keep the spacing relatively tight. For this project we spaced ours 1 1/2″ apart.
Step # 3 Prime
Here’s where the men are separated from the boys. If you really want your lattice to last, you need to prime absolutely everything with oil-based primer PRIOR to assembling. If you prime after, it is built there will be lots of bare, unsealed wood where water will get in and start rotting even the most rot resistant woods.
Prime it or lose it!
Step #4 Assemble
You can use a jig to lay out your lattice pieces or a storey-pole like we did in this case. Either way make sure you mark a centerline so that your lattice pattern is consistently spaced the whole way across.
- Bonding Strips – Using the storey-pole, mark your layouts on the bonding strips and attach the bottom of the lattice flush with the bottom of the bonding strips with one staple (don’t worry, we’ll add more staples in the next step) on both top and bottom. The bonding strips will hold all the vertical lattice where it should be. Make sure your spacing is consistent!
- Frame – Once the top and bottom bonding strips are attached it’s time to attach the frame. The frame goes on only three sides (top and 2 sides). Nail the side pieces flat into the bonding strips using the 1 1/4″ brads. Then, nail the top frame piece on top of the whole assembly. It should be nailed into the side frame pieces and into the top bonding piece along its length every 6-8″.
Your frame should now be complete and ready for hardware cloth.
Step #5 Hardware Cloth
Hardware cloth is an important part of the whole assembly. It should be cut the same width of the lattice assembly, but should be left 6″ long at the bottom. It’s left long at the bottom because when installing the lattice on the house, you’ll need to dig out the dirt and bury the hardware cloth below ground to stop pests from simply burrowing under your lattice to gain entry.
Install the hardware cloth on the backside of the lattice using the same staples you attached the bonding strips with. Along the top and bottom bonding strips, staple it into each individual piece of lattice. This will give the lattice assembly more strength as well.
Be careful that the staples are attaching the hardware cloth. It’s easy to miss the cloth with the staples or blow right through the thin wire mesh if your air pressure is too high.
If your lattice is too tall or your hardware cloth is too short you can simply run another course of hardware cloth. Just make sure to overlap it by at least 2″ and add another row of staples at the overlap.
Step #6 Paint
I’m not going to lie- painting lattice with a brush is a royal pain. If you have a lot to do, I would really recommend renting a paint sprayer or buying a handheld sprayer. It will make the process much more enjoyable.
Apply two coats of high quality acrylic exterior paint to the lattice prior to installation or when it is in place, whichever you prefer.
Step #7 Installation
Since you’ve built your lattice in your garage or shop the hard part is over (assuming you measured correctly)! Dig out the ground and bury the hardware cloth. Then, using Tapcons, drill and screw the side lattice frames into the foundation piers. I use two or three screws per side depending on how tall the lattice panels are.
You can also nail the top of the frame into the bottom of the sill for some extra support and to avoid sagging over the years.
That’s it! You’ve got beautiful foundation lattice that not only protects your largest investment, but also makes it that much more beautiful.
