    The log jam arrived quickly as always. Happy with out it goes on and cleans up, it's very easy to work with. Great product overall.
    Very Pleased
    May 22, 2018

    The chinking arrived just fine. I had purchased some last year to begin working on my house. We have an older log home that really needed to have the chinking redone. I have been very pleased with the ease in which your Log Jam goes and and it really stays put. It is a great product and I will be purchasing more to complete our house.
    Great Product!
    May 22, 2018

    Very Happy With Product and Service

    I'm a repeat customer, very happy with product and service. Wish I could order smaller quantities of log jam, would occasionally like to order one tube, just to test color. Will be placing more orders
    Our house is much better insulated
    January 31, 2018

    It worked great on our older log house. We used the Transformation Wood Finish on our faded logs and then used the Log Jam Chinking between them on the front of our house. The front of the house looks new again. It's never had chinking between the logs before, and now that it does, our house is much better insulated to the point where our pipes no longer risk freezing up in the winter. We really like your products and plan on using the Transformation Wood Finish and more Log Jam Chinking on the back of our house this spring.
    Log Jam Improved Heat and Maintenance
    January 24, 2018

    Our house was built in about 1860 (the cabin portion) of hand hewn and squared oak logs; some of them are 30' long and 18" as squared. The house had mud or concrete chinking for much of its life. The old chinking would crack and fall out, causing heat leaks and looking terrible. We started using Log Jam when we restored the house and it has made a huge difference in maintenance and in heat. Very happy with your product and will recommend it to anyone.
    Log Jam is a fantastic product
    January 24, 2018

    We have a 39 year old log house that was in disrepair before we bought it. Much of the original chinking had pulled away from the logs leaving a very drafty house. We have started the huge process of refinishing the exterior logs and repairing the chinking. We are doing the work ourselves. We have found Log Jam to be a fantastic product. It is easy to use and we were able to match the color of the existing chinking so that we can fill in the gaps and cracks without having to start from scratch. Log Jam is easy to apply and so far seems to stretch and flex as advertised. We haven't had any of it pulling away or gapping. Cost wise, it is comparable to or better than other products on the market. We've used other Sashco products and have been equally pleased. I hope you will continue to be a supplier for Sashco products as I was happy with your service as well.
    Better than the cement/limestone/sand mixture
    January 22, 2018

    Log Jam Chinking works light years better than the cement/limestone/sand mixture we used on the first three interior walls. No more more consistency more maintenance. We're literally and figuratively happy campers!!!
    The best chinking! Super service!
    January 21, 2018

    The Log Jam Chinking I bought and used earlier this year is the best. The service is super and very nice people too. I haven't gotten to use the rest of the chinking yet. But, I'm sure it is good.
    Thanks for a great product and great service!
    January 09, 2018

    We are in the process of building a log home and used the Log Jam Chinking for between the logs. Using a battery powered Dewalt application gun it goes very quickly, and the product is exceptional! The Log Jam Chinking seals better than the Conceal brand we originally used, as it flexes more. Thanks for a great product and great service!
    Worked out very well
    January 01, 2018

    Log Jam worked out very well! It seemed to tool a bit easier than when I used it years ago and with less sprayed on water. That sure helps for clean up afterward. I look forward to ordering more Log Jam sometime this spring.
    Five Stars! Fast Shipping!
    December 29, 2017

    I love this stuff it works great very easy to use. it came out of the tube very easy and the clean up was a breeze I used water and a little foam brush and a piece of foam it looks great . Would recommend it to any one that is working on a log home it is a 5 star product and shipping is fast
    Easy clean up, Fast Shipping!!
    December 18, 2017

    The log jam chinking is working out great. It goes on very nice and looks fantastic when it dries. Makes for a nice rustic look and compliments the logs great. It is also easy to clean up on the logs with a wet sponge or towel. Thanks a lot and what fast shipping. Was on my doorstep within days from ordering.
    Worked well
    December 04, 2017

    It worked well even when applying in not ideal weather.
    Perfect color and easy to apply
    December 02, 2017

    The chinking was the perfect color for the inside of for home, it was easy to apply and although its hasn't been a year yet it seems to be doing the job.
    Glad we chose Log Jam
    November 29, 2017

    The chinking worked wonderful !! It applied evenly and results were very appealing. Received positive remarks. We're glad we chose Log Jam
    Great Product, Easy to apply, Holds its grip
    November 01, 2017

    Log Jam is a great product and easy to apply. It certainly holds it grip. If you need to change out a log it fights to hold that log making it harder to get it out. So just do your maintenance and it will last for years to come. The only downside is how long it takes to cure.
    100% Improvement
    October 27, 2017

    Chinking works great. Since I have a traditional log home, the spacing between logs is not the same so I cannot use it everywhere. But, wherever I used the Log Jam chinking it is a 100% improvement.
    I can trust the outcome
    October 25, 2017

    I can trust the outcome. Have been in business for thirty five years and used Log Jam forever.
    Perfect color and texture
    September 28, 2017

    The log jam worked great. Easy to apply and work with. It looks good and clean up was simple. Texture and the color is perfect.
    Went on great, great product!
    September 21, 2017

    We have finished chinking our addition. The Log Jam product went on great. Loved applying it with tubes rather than from bucket. Great product!
    Nice clean finish
    September 18, 2017

    I find Log Jam easy to work with and over the years have gotten quite comfortable with applying it. The most recent purchase was to chink the inside of my house which had never been done before. We are very pleased with the nice clean look it gives to the interior as opposed to the unfilled joints.
    Enjoy using
    September 04, 2017

    We have enjoyed using your Log Jam Chinking on a lot of projects. We like the small and large caulking gun size tubes and we typically stock tan, mortor white, and grey. We will be preparing another order soon.
    Need to order more!
    August 23, 2017

    Worked great. Need to order another supply of 10 tubes. Clean up process and application were easy. Fingers got tired with the caulking gun. If I ever need to apply large quantities, I would definitely purchase an electric gun. I suspect, the job comes out nicer as well.
    Happy customer
    August 03, 2017

    i am happy with the chinking purchase..the application was easy and color looks great with my log home.
