Easy to apply in cooler weather
February 08, 2018

The caulking was excellent and easy to apply even in cooler weather. Your service was also excellent, quick and efficient. Color matched our logs great! We plan to order more this spring. Thank you!
Big fan of Log Builder!
February 07, 2018

I'm now a big fan of Log Builder! I like it better than Conceal and Check Mate for outdoor work. It's easier to tool and sets up harder, too. It's a much better value.
10 for overall quality and your service is tops
January 24, 2018

Your product worked very good and the color matched our logs really well. Our 8" wood log Cabin from time to time naturally has cracking or checking as some call it appear horizontally which gives the cabin character as they say. Your product can be used by itself or for larger cracks backer rod can be used first then your caulking applied over that for an even finished look that blends well and seals out the element and bugs of any kind that might try to invade your home. When I need more I will be back. I give your product a 10 for overall quality and your service is tops.
Flexible for 14+ years
January 24, 2018

Log builder is the only caulk I like for my 120 year old home. It spreads and adheres extremely well, is flexible for 14+ years and takes stain.
So far pleased
November 24, 2017

The original caulking on our log home had started to crack and fall out so decided to try your product. I did a small section of the house and so far I am pleased with the results. In the spring I plan on doing the rest of the house so I will need about 5 times more than I ordered for trial attempt. I will also want to explore an easier way to apply than the manual caulking gun along with a discount for a volume purchase.
Very Happy
October 29, 2017

We are very happy with how the caulk worked. We will be reordering soon. Thank you.
Will continue to use
September 14, 2017

I have used the log builder caulking before my latest purchase and it has worked out well for me. I will continue to use this product
Works Great, Color Great, Easy to Use
August 29, 2017

The Caulk worked great and color was great, was easy to use and will be purchasing the Log Jam soon for Chinking.
Went on great
July 27, 2017

The product worked great once I got used to it. At first it went on too thin but after I got the hang of the texture, it went on great.
