A Guide To Buying an Existing Log Home

You want to buy a log home, but, you don’t really know what you’re looking for and how to check if the cabin is in good condition.

Unfortunately, you’ll probably find that most home inspectors don’t know much about log homes, so how can you make sure that you buy the right log home?

You’ll most likely be able to find a local inspector who specializes in log homes, even better if they are a certified or licensed home inspector, however, it will become quite costly for you to have every single log home you view, inspected.

In all my experience of the hundreds of log cabins I have seen or offered advice on, I am yet to see one which is past repair. Perhaps a more appropriate question is not whether a cabin can be repaired, but the cost of the repair.

We would suggest that you follow the checklist below, before reading the article for more detail. Once you understand key inspection items to look for, and narrow your search down to one or two homes, then you can consider paying for an inspection.

Exterior Inspection

You can expect a log cabin to perhaps look a little dirty and even expect to see some flaking on the finish, but when does this become a problem?

Let’s take a look at each of the elements you’ll need to look at on the exterior of the log home:

1. Staining
2. Logs in contact with the ground
3. Rot
4. Overhangs/Exposed Logs
5. Gutters
6. Insect Infestation
7. Chinking
8. Checking
9. Decks & Porches

Staining

Log Cabin Stain Exterior Inspection

Water is the number one enemy of log homes. Not that it’s a problem for logs to get wet – that’s fine, they dry.

The issue is when they don’t dry and then start to rot, this is why most log homes are stained or have some weatherproofing.

It’s quite easy to tell how good the staining is, usually just by eye.

What does the staining look like? Can you see bare wood anywhere? Is the staining patchy?

Pay attention to the south and west walls of the cabin – are they faded? Are the logs a different color on the top than they are at the bottom?

Don’t be afraid to ask when the home was last stained, if it was over 15 years ago, it could be a very expensive job to corn blast the home and then re-stain.

If the stain is even but just really worn down, this won’t cost much to fix. Check out our maintenance guide for details on how to stain it and costs.

If you’re still unsure about the staining, a simple way to test how effective the staining is is to splash water on the logs. The water should bead up – this shows the finish is still effective.

If the water is absorbed, this is not a great sign – the stain is no long effective.

This doesn’t mean necessarily that you shouldn’t buy the cabin, you’ll need to consider the other points of inspection too.

Logs in contact with the ground

Be extra cautious if you see that the base of the log home is in contact with the ground, or any other logs are in contact for that matter.

When I talk about the ground – I mean dirt and mud.

Logs that lay on the ground will soak up the moisture which could cause the logs to rot.

Not only do they wick up moisture, but they will also make a nice home for insects, giving them easy access into the cabin.

Make sure there is at least a 10-12 inch gap between the ground and the logs.

If any logs are in contact with the ground, find out if they are pressure treated. Logs that are pressure treated have a better chance of resisting everything that wants to eat it (insects, bacteria, fungi etc.). If the logs in contact with the ground have not been pressure treated –stay clear!

Rot

If you’ve spotted logs in contact with the ground, or inadequate staining, it is very important to consider this inspection step thoroughly.

In a more obvious example, you might be able to see black marks on the outside of the logs – this is not a good sign. It’s likely that the logs will have rotted from the inside out and so therefore won’t have much life left in them at all.

Sometimes, logs may look completely fine from the outside, but have hidden rot on the inside. But how do you tell?

Look for the logs that are in close contact with the ground, around windows and doors, the first few logs, logs around decks, porches and corners, and any logs with a flat surface and perform the following test;

Take a hammer with you and ask for permission to tap on the logs. You’ll be able to hear a difference between a log that is rotting and one that is not.

A log that is rotting will produce a hollow sound compared to a solid log. Also, some logs with interior rot usually bounce the hammer back, whereas a solid log with stop the hammer.

If you suspect that logs are rotting, the only solution is to replace them which can be very costly.

Overhangs/Exposed Logs

Log Cabin Inspection Roof Overhang
It’s important for a log home to have an overhanging roof to keep the rain and other elements away from the logs and the foundation.

Ideally there should be at least 24 inch roof overhang for a one story house, and 36 inches for a 2 story house.

Having a shallow overhang is not great because as the water runs off, it will hit the ground and splash back on the cabin.

Gutters

Log Cabin Gutter Inspection
While gutters don’t really add much to the aesthetic beauty of a log home, they are an important part of preventing water from contacting the logs.

You should make sure that the gutters are in good condition and are clear from debris and check that the downspouts drain the water away from the house and the foundations.

Insect Infestation

What are the signs of insect infestation, aside from the obvious insects themselves?

Tell-tale signs include bore holes (each insect makes a different size and shape) and chalky, powder like residue. An odd hole is expected, it’s when you see a group of them that there is a problem.

Carpenter ants, carpenter bees, powder post beetles and termites are just a few of the insects that are common insects to infest log homes. Carpenter ants and bees both shed their wings before entering the holes so you may also find wings.

Most insects invade log homes because they like the moisture, therefore the most effective way to reduce insect infestations is to get rid of rotten logs and replace them.

Chinking and Checking

Chinking is the sealant between the logs. In particular, you should check the condition of the chinking and that is it all intact.

If there are: chunks missing; gaps or tears; or if the chinking is messy, this shows the cabin hasn’t been maintained very well. Chinking is easy to remove and replace, so poor chinking is not an indicator that you shouldn’t buy a log home, rather, an indicator of poor maintenance.

Remember, older cement-based chinking requires far more maintenance than today’s supple elastomeric chinking that moves with your cabin as it settles – cabin maintenance

Checking
Checks are splits or cracks in the cabin’s logs. Checking is a normal part of logs drying out.
The only time it becomes a concern, is if the cracks are over 1/4” in size, or if they lie on the upper side of a log, making it easy for water to infiltrate them.

Cracks and checks can be filled with sealant or chinking, but you should first check that water damage has not already been done – refer back to the rot section.

Settling & Shrinking

Log Cabin Roof Collapse During Settling
All log homes are likely to settle and shrink slightly in the first few years; as they adjust to their climate and lose moisture.

Most log home builders will take this into account and allow for shrinkage.

Signs to look for that a log home didn’t settle properly include windows and doors sticking or not opening and windows and doors bowing from the weight of the walls.

Look at partition walls, which are normally not logs, if a settling allowance wasn’t made there will be a big problem that the exterior walls will have shrunk and will now be putting a lot of pressure on the interior walls, which in the worst case scenario could cause them to fail and collapse.

Check that the roof doesn’t have any humps or dips. This could also be a sign than the property didn’t settle properly.

Decks & Porches

Porches are a great addition to log cabins – they shelter the logs and reduce the wetting and drying cycle, whist protecting the logs from natural elements (i.e. rain and sun).

With the benefit of porches and decks also comes a downside.

If the overhang is not large enough, or if there is no roof on the deck, then water will drip down from the roof and splash back on the cabin. Check these areas for water damage and rot.

Interior Inspection

Log Cabin Interior Inspection

Once inside the cabin, you should be looking for all the same things as you did on the exterior, but you will also want to check for light and air infiltration between the logs.

Look in particular at the joining between the wall and the roof, and the roof rafters, purlins and ridge beam. Again, you should be checking the chinking and for any signs of insect infestation.

Staining is not as important on the interior as it is on the exterior, but I still recommend it so you should therefore also be checking for water and mold.

Documentation

It is also useful to visit the local town clerk’s office to find out how many times the house has been sold and how often. A log home that has changed hands often may be a sign that there are problems with the home that people don’t want to deal with. In contrast, a home which hasn’t had many owners is likely to have been well looked after and maintained better.

Questions you should ask

When performing your log cabin inspection, other questions you can ask when you go to view a log home are:

  • When was the last time the cabin was stained/chinked
  • When was the cabin built?
  • How many owners has the cabin had?
  • Who built the cabin?
  • Are there are disclosures that need to be made, specifically on rot, insects and drainage?

Summary

Let’s have a quick recap on the most important areas to check when you’re thinking of buying a log home?

Check the exterior logs for staining, chinking, checking and water damage. Check the roof for humps and dips, and that is has appropriate gutters.

Check for insect damage and how the log home has settled.

Remember that water is the number one enemy of log cabins, as this is where most of the problems stem from, so ensure that you buy a watertight and waterproofed log home.

Once you have used this article to narrow your choices down to a couple of homes, I would suggest paying a log home specialist to inspect the property.
