Log home repair – What can you put off until next year?

Now that the warm weather is behind us, we are busy finishing up the jobs we have lined up for the rest of our season. Once the snow flies, we take a break from log work and refinishing until next spring.

We are getting calls from people who are looking critically at their log homes and realizing that they are in need of some log home repair services.  They also realize that it is getting late in the season and they are wondering if it is detrimental for their logs if they wait until next year to have the repairs done.

blasting

Don't do the blasting if you can't get the stain on it soon after.

Here is some general advice: If you are thinking that the finish on your log home needs to be removed, but you are not sure you will be able to get it re-stained before the cold weather sets in, it is better to wait until spring to have the finish blasted off so that the new stain can be applied shortly following the blasting process. Letting logs go through a winter with no stain or protection on them is not advised.

What about logs that you know are rotten? Will they continue to rot over the winter and be even more deteriorated come spring? This is where cold weather is a benefit to logs with rot. The microorganisms that cause rot need to have temperatures in the 60-90 degree range. Once the temp drops below that range, the rotting process is halted temporarily until it warms up. Having said that, it is important to make sure that in the spring, the snow piles are not left to melt up against the logs. Moisture up against the logs is a problem waiting to happen.

cracks

A good example of checks that should be filled before winter.

The one thing that is advisable to do yet this fall is to check for cracks that are wider that ¼” and are on the up-facing side of the logs or in vulnerable places. Filling these checks with a quality caulk will keep the moisture from snow and rain from migrating into the logs and causing problems with rot.

We are still doing estimates for people who are interested in having log home repair services done yet this year and we are also lining up projects for next spring. Give us a call at 877-378-4403 if you are interested in getting an estimate OR contact us via email.

Log home dry rot and what can be done to resolve it

dry rotWe frequently get calls from log home owners saying, “My home has some dry rot.” When you look at the logs affected with rot, they DO look dry.

Whether the rot is dry or wet, rot equals decay and that is a serious problem in log buildings. Rot can lead to the need for replacing part or the entire log. There are several factors that can contribute to a log getting rot, but they all have to do with moisture getting into the wood. When wood fibers have a constant moisture level between 14-20%, wood will start to rot.

Log restoration – Replacing crowns

rotten crown

Someone else had previously repaired this corner. Notice there the exposed remaining rot and the lack of a scribed fit.

Log restoration and replacing rotten logs is what we specialize in.

Sometimes we get calls from people who have hired other contractors do work on their log homes. We inspected this home this summer, where another contractor had replaced a crown a few years previously. As you can see, there are a few problems with this installation.

First of all – the log was not properly fit into the space. Sections of rot were not removed and the log chosen for the replacement was not as big as its predecessor.  Also pine was used as the replacement log.

rotten crown

Notice carpenter ants already working on this pine log. A dried cedar log is best used here.

In the short time since the log was installed, the wood boring insects have taken up residence. The rot has begun here and the efforts made to remove and install the new log were in vane.

The work needed to be done right the first time. Replacing rotten crowns is a time consuming process and the right size and species of replacement log needs to be used.

crowns replaced

Here is an example of a stack of crowns we replaced.

We use cedar kiln-dried logs because they will not rot or shrink.  We can also match the stain on our replacement logs to the surrounding logs, unlike this example.

Why do logs rot?

Log home dry rot is a bit of a misnomer

A log with dry rot.Log home dry rot is not uncommon in log buildings. One of the most common complaints from log homeowners is that their logs have “dry rot”. Whether the rot is dry or wet, rot equals decay and that is a serious problem in log buildings.

Rot can lead to the need for replacing part or all of the log. There are several factors that can contribute to a log getting rot, but they all have to do with moisture getting into the wood. When wood fibers have a constant moisture level between 14-20%, wood will start to rot.

Simply put - rot is caused by moisture, even though it may appear to be dry. There are several factors that contribute to log home dry rot. Learn more about why logs rot.

Log home repair – how to check for rot

Log home repair starts with knowing when you actually NEED repair. Here are some tips for discovering if you have rot in your logs that needs attention.

finish buildup

Notice the grayed log compared to the surrounding logs. Rot!

Tapping on the logs is a simple and effective method of discovery. It is not 100% accurate but it is definitely worth doing. Use a hammer and tap on logs that you suspect may have some rot. Are they darker or grayed compared to surrounding logs? Are there lots of checks or cracks in the log that make it look suspicious? Are there small holes in the logs, which may be an indicator of boring insects (a sign of carpenter ants or powderpost beetles. Find out more…)

problems with insectsIf the sound you hear when tapping these suspect areas sounds different than when you tap on logs that look “healthy”, it may be an indicator that there is rot. To really do a thorough check by tapping, it will require a ladder to get to higher areas. If this is not possible for you to do yourself, it is worth getting someone who is comfortable with heights to get up there and do it for you. Rot can take hold underneath windows and underneath decks so be sure to inspect these areas regularly.

Check the ends of the logs (crowns) and if there are lots of checks, pay special attention to them. Are there soft spots? Are there places where pieces of the wood have broken away from the log? If these crown ends extend beyond the drip line of the roof, they are particularly susceptible to rot.  Water from the roof can hit one crown and then drip or travel down the entire stack of crowns, causing serious damage.

Our log home repair services includes replacing rotten logs with partial logs or worse case scenario, replacing the full log in a given section.  Replacing crowns takes some experience and skill if you want the new crowns to blend in with the original ones. Learn more about how we replace rotten sections of  logs, whole logs, and crowns.

Chinking log homes – An important part of maintenance

The chinking and caulking in log homes should not be overlooked. Routine maintenance of your log home includes keeping an eye on sealing up the gaps between the logs.  The design of some log buildings requires chinking or caulking but for others, it becomes necessary to do this for various reasons.

chinkingBasically what we are doing when we chink or caulk is filling the gaps between the logs or between logs and windows, doors, foundations, roof lines and other areas where we want to prevent air and water from making its way into the log building or cabin.

While prevention of rot is always our primary concern, energy savings can be another big reason why people chink their log buildings. We have had customers tell us they were able to take advantage of tax credits related to energy savings based on chinking their homes.

Chinking and caulking both rely on latex polymers for adhesion.  The basic difference between caulk and chink is that chinking has fine sand particles added to it. This sand makes the appearance of the chinking dull or “flat” and in the same way that aggregate adds strength to a concrete slab – the sand adds strength to the chinking material.

Modern chinking material adheres much better than traditional caulking. Chinking can be used on lines that are from 1/2″ wide to more than 6″ wide.  If the lines we want to seal are less than 1/2″ in width, we usually recommend traditional caulking or a product called Energy Seal.  Perma-Chink is our preferred brand of chinking.

chinking behind trim

This is not what you want around your windows or doors.

Sometimes it is necessary to install foam backer rod behind the line of chinking. The foam rod insulates the line of chink as well as breaks the bond in the center of the line, allowing for more flexibility within the chinking material for when the logs naturally expand and contract.

caulking around window

This is what we have done to take care of this problem.

An often over-looked area as far as chinking goes is the transition between the windows and the backside of the trim around the windows or doors. If left un-sealed, these cavities become places where water and air can make its way into the home.

The other reason to fill these cavities is that critters (bats, bees and mice) love these areas and find it a fitting home or way to get into your house.

Chinking your log home can solve a variety of problems. We have over 30 years of experience with this technique and we can complete your project in a professional manor. Contact us or call 877-378-4403.

Log Home Refinishing – Log rot resulting from film-forming finishes

Log home refinishing is more than just applying another coat of stain. Sometimes it’s necessary to remove the existing finish completely, getting back to the bare wood, and then apply new stain. When a log home is finished with a quality log home stain and that stain is maintained properly, rot can be avoided.

up-facing cracks can lead to rot

Darkening logs is indictitive of failing "film-forming finish". This one had up-facing checks that caused some of the rot issues, as well.

In our 30+ years in the log home restoration business, we have seen many disastrous problems with rot in log homes that were related to the finish on the logs. Some of the most tragic problems we have seen have been the result of having what I refer to as a “film-forming finish” on the logs.

It is a widely accepted rule in the log home industry that we expect finishes on log homes to breathe. Logs naturally have a large ability to soak up moisture and so any finish that is applied to them needs to be breathable to allow the logs to dry out when they get wet. Film forming finishes are defined by the fact that they sit on the surface of the log and after the initial application don’t generally soak into the wood at all. Instead, they form a film on the surface of the logs.

When the wood gets wet (and stays wet), it causes problems. The problem with these film-forming finishes is that they do not allow the wood to breathe enough and this in turn can lead to some serious rot problems. Film-forming finishes include the Sikkens Cetol system and at least one of the Behr “premium” stains.

serious rot

This is some serious rot.

We have found that most times the problem begins after the second application of this type of “stain”. It may be that the buildup does not become problematic until that second coat is applied. Blackening of the areas in question is the first sign that there is a problem with moisture. Once the blackening starts (see photo), it becomes necessary for log home refinishing services: blasting and re-staining.

In conclusion, it is my professional opinion that there is no place for this type of finish when it comes to log home refinishing. We see too many log homes with these finishes on them and the problems are consistent. Stay away from “film-forming finishes”.

Log Home Maintenance – Proper uses for different types of Borates

Log home maintenance often includes the use of borates are a preservative for the logs. There are basically three forms of borates: liquids like PeneTreat, Bora-Care or Tim-bor; pure borate rods like Impel Rods; or mixed borate rods like Cobra Rods.

PeneTreat is a powered borate. The powder is mixed with water and applied to bare wood. It treats the wood in general for rot and also prevents infestations of wood boring insects.  Bora-Care is a highly concentrated borate where the borate is mixed with glycol to promote penetration into the wood.

We use and recommend PeneTreat where we want general protection for the wood.  It comes in the form of a powder and is typically mixed at one pound per gallon.  Bora-Care is a gel, which is also mixed with water, usually 1:1. This mixture is then applied to low, up-facing checks, lower logs that are getting wet all the time, window sills that need extra protection and crown or log ends. These borates offer good protection from rot when used in conjunction with a quality log home stain.

Borate rods or Crystalline Solid Borate Rods are either pure borates in rod form or borates mixed with copper hydroxide.

• Impel Rods are a pure borate rod in a solid form
• Cobra Rods are a mixture of borate and copper hydroxide

We generally do not  recommend the use of these rods for log home maintenance.  We have found that the drilling of holes into the logs to insert the rods promotes decay in itself and for this reason, do not recommend them.

This said, we see them used all the time.  Many times they are inserted too late in the rot process to do any good. In this situation, they do more damage by actually promoting decay rather than acting as a prevention for decay, as advertised.

In conclusion, borates in general are a good thing. Use the liquids such as PeneTreat, Bora-Care and Tim-bor and there are other brands. It’s all really the same stuff packaged in a different way. These are good ways to get borates into your logs to protect them.  Understand that borates are prevention… not repair.  Borates will not “re-solidify” your logs.  Rot is rot.  The wood will need to be replaced if it is rotten.  Maintenance of your log home depends on the wise use of borates.
