About Us

Since 1924 J.J. Jefferson has serviced Western Washington as a Specialty Contractor who offers plaster of all types. It was founded in 1924 by Joseph J. Jefferson. The company was passed on to his son, Joseph Jr. who passed away in 1965, and the company was purchased by Mack McGlothlen. In 1985 it was sold to Pat Callahan, Don Mehrer, and Morris Mehrer. In 1988 the Mehrer brothers assumed full control of the company. Then in 2008, Morris became the sole owner.
We Love Our Customers!

The best in town! I hired another contractor who was super nice, and tried his best, but the finished product just was not the top quality we were looking for. Enter JJ Jefferson & Son! They made the plaster perfectionl!! I could not be happier. They are the only plasterer we will ever use again. So, so delighted and pleased!


Great to work with and they did a fantastic job!!!


Awesome company to work for! Every person I have worked with has a great personality and moral principles. As an apprentice, I have already learned so much from each person because of their skill and talent for plaster and stucco work. Look forward to becoming a journeyperson and growing with this company!


The team from JJ Jefferson & Sons Inc did outstanding plastering work in our home! We are very pleased with their work quality, timeliness, site management, cleanliness, and client communications throughout our project. We highly recommend JJ Jefferson & Sons!


Without question this company is the best we've ever experienced. They did a wonderful job. It turned out that there was more water damage than we thought but they got in there took care of the problem efficiently and were very fair in their pricing. I cant say enough good things about them. Best money we've ever spent on home repairs!


These guys are awesome, super friendly and experienced with pretty much any stucco work you could ever need. They've completed tons of projects (big and small) in the area. If you're in the market for plaster, stucco or EIFS, I highly recommend giving Joseph J Jefferson a try.


Great work!
