Energy Seal

Energy Seal

five star

Textured Log Caulk

Since it was introduced, Energy Seal has become one of the most popular members of our sealants. Energy Seal was created specifically to seal milled or scribed log homes, log siding homes and around joinery such as butt-joints, trim and corners. One application makes any log wall completely weather-tight.

Energy Seal has excellent adhesion and stretch. It is long-lasting, UV-stable and chemical-resistant.

Unlike commonly used sealants which look shiny and artificial, Energy Seal is textured to match the visual characteristics of wood. It easily tools to a smooth, professional finish, virtually disappearing into the walls after it's applied. It softens the lines on log walls and accepts the color of wood finishes. In fact, Energy Seal so closely matches your walls, most people can't tell the seams are sealed.

Application can be done by the homeowner or a professional contractor. We stock a full line of application accessories or can refer a professional applicator in your area.

five star Bill on 04/07/2019 - "I've used Energy Seal caulking for over 3 years. Energy Seal is a great caulk that doesn't shrink or crack and can be stained or painted. The color representation on line is accurate. Great product."

five star Ed on 03/05/2019 - "This product adheres to wood the best of anything that I have ever seen. It never seems to crack or pull loose. I have been using it for the last fourteen years and have not experienced ANY problems with it. It is tough, elastic enough to "give" some, and super strong. It is a truly great product."

five star Tim on 11/03/2018 - "I have a "D" log type home so no chinking was required. But, I have used a combination of caulking and chinking to seal between logs and for checks. But then I discovered Energy Seal! What a great product! With my Cox applicator, it goes on easy with easy clean up. As it cures, it blends into my logs very well leaving a much smoother looking finish. Thanks again for another great product!"

five star Diane on 11/02/2018 - "I love this product! We completely restored our log home in 2013 and included Energy Seal as one of the key components to sealing all of our doors and windows. Remarkable product, easy to apply, stained very nicely to match our logs, and still holding true this year!"

five star Daniel on 9/19/2018 - "Energy Sealer is an impressive caulk, remains amazingly flexible after two years of very high/low temps and is water resistant."

five star Sonia on 6/05/2018 - "Well, there were many, MANY delays getting to the job site to try out Energy Seal, but I finally got there this week. I love the product, it was great to work with and looked really beautiful. I now need to sit down with the sales staff to look at future air sealing projects and see where we go from here.  I am all in; now let's see what is next for Farnum Insulators. "

five star Vicki on 6/01/2018 - "I have a flower shop and I use Energy Seal to seal gaps around my windows and doors. It made a huge difference inside."

five star Nathan on 3/14/2018 - "Easy DIY product. Great spatula is a must. Thank you!"

five star Jeff on 2/22/2017 - "Very pleased! I used it to fill in several Carpenter Bee holes after treating them and this caulk blends in well with the logs. Brian ( at the online store) sent me a document about dealing with Carpenter Bees and it listed several products which included Energy Seal that I could use."

five star Bree on 2/17/2017 - I think this caulk will work. We purchased a couple tubes of Classic Brown to fill in few gaps between the logs. It was not dark enough, but we purchased a few more tubes of the Walnut color and it matches our logs MUCH better! We painted over the Classic Brown, so it matches a little bit better now."

five star Nel on 2/13/2017 - After completing a web training with Perma-Chink, we took on sealing our "chinkless" home and it went really well. The product performed exactly the way Gabe in the Redmond store said it would and with his help and extra tips, we are extremely happy and the home is much more airtight."

five star Art on 2/9/2017 - Easy to apply log home sealant from a company that's been doing this for many years. Great customer service and quick shipping. Great experience!"

five star Phil on 1/26/2017 - So glad I found Energy Seal, it is exactly what my log home needed! I have a Swedish Cope style log home that my builder said would never need a sealant, well after 3 years I started to realize he was mistaken. No more draft and better energy efficiency with Energy Seal Sealant!"

four star Jaqueline on 2/7/2017This Energy Seal caulk is a little hard to spread at first with a spatula, but we got the hang of it after awhile. Be sure to use a spray bottle to mist it and then smooth it. I recommend looking at the document on the website about Energy Seal application before starting. Overall, I am pleased. It was a lot of hard work, though.

four star Jillian on 1/31/2017 - I ordered a 30 ounce tube of Energy Seal from your online store and used it to caulk/fill in gaps around my window frames on the outside. The color I used (Cedar) looks great and blends in with the stain pretty well. I would probably get the smaller tubes if I need this product again since the 30 ounce tube was a little heavy to handle when caulking."

four star James on 1/28/2017 - Very easy to apply for a do-it-yourselfer. Instructions online with permachink were clear. Astonished at how fast I received the product. Ordered twice and got the large pails the next day both times without expediting shipping."

five star Phil on 1/26/2017 - So glad I found Energy Seal, it is exactly what my log home needed! I have a Swedish Cope style log home that my builder said would never need a sealant, well after 3 years I started to realize he was mistaken. No more draft and better energy efficiency with Energy Seal Sealant!"

five star Jim on 9/29/2016 - I was recommended this product by my Log Home Builder, it was easy to use once you get the hang of it and looks and performs as advertised."

four star Gill on 9/16/2016 - I like the 11oz tubes, they are light and easy to work with, shipping is super fast! "

five star Eli on 9/14/2016 - Great product for sealing our coped log home! We started out using the tubes, then changed over to the pails/bulk loading gun process and it went really well. It seemed a little sticky to tool out, but once you get used to it it's really easy to work with. Stained over it and it blended in perfectly!"

five star Amie on 4/26/2016 - Great product! I used the bulk caulk gun and the follow plate with the Energy Seal pails. Natural Pine is the color I chose. I used it to seal around my windows, doors, and my exterior log joints. Would recommend it."

five star Zak on 3/24/2016 - "Energy Seal was a perfect Log Cabin caulk for our family getaway. It tooled out nicely and blended in with the logs perfectly."

five star Chad B, Owner at Solid Log Construction in TN (01/28/16) - “The Energy Seal does exactly what it is designed to do; prevent destructive air and water infiltration! I have used other sealant products and find that Energy Seal is very durable, stainable, and pliable. Once it is applied according to Perma-Chink’s recommendations it will be stuck like glue. We have used this product for a long time and will continue to use the product because it does what it is supposed to do. We are so confident in our craftsmanship and the Energy Seal we give our customers an air and water infiltration warranty. If it leaks we come back and fix it for free.”

five star Jo at Premier Painters, LLC in ID (07/23/14) - "We have been applying Perma-Chink Energy Seal for over 13 years on a commercial level. Our customers like the choice of colors and finished look of Energy Seal. As log home finishers, we find it very useful for sealing around windows and doors, leaving a nice finished look that blends well with Perma-Chink stains. It is great for sealing out bugs and its water cleanup is convenient. We highly recommend this Perma-Chink product!"

five star J Benson in CO (05/23/14) - "Energy Seal was a surprising product for me. I intended to use Perma-Chink, but after talking with Shar, she helped me discover that because my spaces between the logs were small, about 1/2", that I should use Energy Seal. This really saved me $$ and it looks beautiful! Just the look I wanted. Thank you Perma-Chink!!

five star C Washburn in MT (06/05/2013) - "I like how the Energy Seal is textured to match the characteristics of the wood. I used this product around the door and window trim and it really just blended in with the wood. Looks Great!

four half star A Eromin in MN (07/27/2011) - "I found it easy to apply and appreciated the textured finish. Really blended in to the wall for a cohesive look. I'm glad there was a good selection of colors to choose too."

five star B Corvey in AL (09/25/2010) - "Been on the house for about 3 years now. Still looks great. I’ve recommended Energy Seal to a few of my neighbors even"

four half star R McConnell in OH (02/10/2008) - "We found out that what they say is right, "there is no such thing as a chinkless style home". So we applied Energy Seal when our logs started expanding and contracting and gaps were opening up. It's made a big difference and saved us a lot of money in heating and electric bills."
