Hired on Thumbtack

I recently hired Jason to repair and paint the exterior trim on my home, and I couldn’t be more impressed with the results. From start to finish, he was fast, efficient, and professional. He showed up on time, communicated clearly throughout the project, and demonstrated a high level of knowledge and skill in his work. Jason was incredibly reliable and worked with care and precision. The quality of the repair and paint job was outstanding — it’s clear he takes pride in what he does. He made the entire process smooth and stress-free, and I appreciated how easy he was to work with. I highly recommend Jason to anyone looking for a trustworthy contractor who delivers top-notch results. I would absolutely hire him again without hesitation. A solid 100% recommendation!

Details: Wood • No, I will need the carpenter to provide the molding or trim • This is just an installation job - no design needed • As recommended by carpenter • 0 - 40 ft • I would like it painted

Jason has been very helpful. Although we hired him for baseboard and crown molding, he was also able to help out with several other projects in our home. We are very appreciative for his help and professionalism.
