Gaps between logs are pretty common in log cabins, but you wouldn’t want them to leave them alone. Otherwise, this could cause water damage, make the cabin colder, and so on. If the gaps become too noticeable, they can also affect the appearance of your cabin. Bit more than just a gap, isn’t it?
One effective way to maintain the integrity of these garden buildings is to fill in these cracks. In this guide, I’ll walk you through why it happens, how to pick the right filler, and how to fix it.
How Do Log Cabin Gaps Form?
Gaps can occur for various reasons, like weather changes, the natural ageing of the wood, or just the settling of the logs with time. It usually starts with small gaps as the timber shrinks and expands with the temperature. They can get wider and cause a few problems if left unchecked.
For instance, cracks can let drafts in. This can mess with your cabin’s energy efficiency and could push up your heating or cooling bills. On top of that, moisture can sneak in through, manifesting rot and mould growth. Such cases can be particularly annoying if you use the space for things like relaxing or working from home (e.g., a garden office).
Taking care of those gaps will help keep your cabin strong and looking great. So, it’s worth making it a regular part of your upkeep.
When a log cabin is still new, gaps can form between the logs as they begin to settle. It is sometimes necessary to unscrew a log from part of the framing to allow it to drop and find its new position on the structure, therefore closing the gap.
How Do You Tell How Bad the Gaps Are in Your Log Cabin?
Different gaps might need other ways to fix them, depending on how big or deep they are. First, look around and check for any wider or deeper cracks. You can use a tape measure or callipers to measure them if you want to be precise. This will give you an idea of how much filler you’ll need and what kind.
It might be worth getting a pro if the gaps are big or complicated. They’ll know exactly what to do and can suggest the best way to fix things properly.
Picking the Right Filler
You can use a few materials, depending on what you need. Here’s a quick rundown:
Chinking
Chinking is a flexible sealant made from things like mortar or synthetic compounds. It’s great for bigger gaps because it moves with the logs as they expand and contract with the weather. The downside? It can take some time to apply, but it’s worth it for larger cracks.
Caulking
For smaller gaps, caulk, like this silicone and gun set, is your go-to. You can get it in silicone or latex, and it’s super easy to apply with a gun. It does a good job sealing things up, but it might need topping up every now and then. Just keep in mind that it’s not always the prettiest option.
Foam insulation
Foam insulation, like expanding polyurethane foam, is effective for small and large gaps. It provides excellent insulation properties and helps with energy efficiency. The only thing to watch out for is that it can expand quite a bit, so you’ve got to be careful when applying it. And if you ever need to remove or replace it, it can be a bit of a pain.
For smaller gaps, caulking tends to be the easiest and cheapest option. But for bigger gaps, chinking is the way to go, especially if you want that traditional log cabin look. If you’re after serious insulation and need things to be properly airtight, foam is your best bet.
Prepare to Fill the Gaps in Your Log Cabin

- Grab a stiff brush or vacuum cleaner to get rid of any dirt, dust, or loose bits in the gaps. This will help the filler stick better and give you a cleaner surface to work with.
- If there’s any old chinking or caulking that’s gone all manky, you’ll need to scrape it out. Use a scraper or chisel to remove it, making sure the gaps are clear before you start filling them.
- Good airflow is key when you’re doing this, so make sure to open the windows and doors or even use a fan to keep the air moving. This is especially important if you use anything with strong smells or chemicals.
- And don’t forget your protective gear! Pop on some gloves and safety goggles to keep yourself safe while you’re prepping. If you’re working with chemical stuff, always check the instructions for safe handling.
Quick How-to for Filling the Gaps
How you fill the gaps depends on what material you’re using, but here’s a general guide to get you started:
- Prep your filling material according to the instructions. This might mean mixing mortar for chinking or loading up a caulk gun for caulking.
- Get to work applying it into the gaps with a trowel or your caulk gun. For chinking, the material should fill the whole gap, while for caulking, just run a nice, even bead along the length of the gap.
- Once it’s in place, grab a putty knife or a chinking tool and smooth it all out. The edges must blend in with the surrounding logs.
- For a tidy finish, stick to the same technique and colour throughout.
Note: Different materials might need slightly different methods. Chinking, for instance, needs to be pressed in firmly and then smoothed to get that textured look. Caulking, in contrast, is usually smoothed off with a damp finger or a special tool.
Round-up
Filling the gaps helps keep your cabin looking great, sturdy, and energy-efficient. Just understand what’s causing them, use the right filler, and make it part of your regular log cabin maintenance.
