- Joy Cramer

I had Northstarr back for a second time to build a ramp to my deck and redo a pantry. Woody did the carpentry work on both projects. He was great to work with and listened to what I had in mind and discussed options with me. He showed up every day on time and worked hard all day long. Before he left each day he cleaned up his area and was respectful of my property. I love my new ramp and pantry! Already planning my next project now that I have a trustworthy company to work with that I know will do a great job every time.

Hired NorthStarr Builders LLC to refinish a deck that was built in 1977. NorthStarr Owner, Marty Johnson helped us think through whether to replace with a composite material, or sand and refinish existing deck. Ultimately, he recommended replacement of existing surface with a newly introduced product - a cedar-toned treated yellow pine that looks beautiful and fit best within our budget. NorthStarr also stripped and refinished a bench/trellis section of the existing deck to match the new deck material. I appreciated that Marty was a very responsive communicator all through the project and worked with us to address some glitches that inevitably come with a large project like this. In my estimation, the measure of a good company not only regards their workmanship, quality and responsive communications but how they resolve issues. On all such scores, I give Northstarr Builders high marks and recommend Marty and his great team with enthusiasm.

Needed a wall with a door built in my finished basement. Marty came out quickly to quote the job, and was able to fit it quickly into the schedule. The crew that executed my project was very professional and did an awesome job!

Multiple projects completed professionally Home looks brand new . Beautiful. Customer service was EXCEPTIONAL. Always able to reach Marty when needed and calls and texts were returned quickly. Could not have asked for a better crew to work on my home. Highly skilled and committed to excellence. Definitely went above and beyond. So very pleased with the final project. Would definitely recommend to others.
