Justbo Painters is a one-crew outfit run by James Libby out of Allston, doing business under its registered name, Justbo Building Co, at 56 Riverdale St in Boston. The reviews keep returning to the same idea: hire Jimmy for a paint job and he tends to leave having fixed a few other things too — patched drywall, hung cabinets, swapped a lock, rerouted a basement door. The clearest signal is recent: five 5-star Google reviews landed between March and September 2026, with nobody complaining about a thing. That streak sits on top of a deeper history — fifteen reviews going back to 2020, spread across Google, Thumbtack, Angi, HomeAdvisor and BuildZoom, where the company carries a 5.0-star average from 8 ratings and a BuildZoom Score of 120, in the top 1% of Massachusetts contractors. A 2022 review describes a condo association hiring the crew to strip and re-shingle a section of their building, finishing a day ahead of schedule; a 2021 review recounts years of repeat work for one homeowner — a porch redo, a rerouted basement door, and, most recently, custom-built bunk beds. BuildZoom lists an active Massachusetts Home Improvement Contractor registration (#194899) and an active Construction Supervisor license (#CS-087010) for Libby, alongside an older HIC number marked inactive — those are directory claims rather than something verified here against the state registry, so it's worth confirming current status directly before signing anything. Tenure claims also don't quite line up: Thumbtack's bio says 'over 30 years' (with a separate badge reading 45), while Angi and HomeAdvisor list 7 years of experience. For a straightforward interior or exterior paint job — especially one that might turn up a patch of rot, a stuck door, or a cabinet that needs rehanging — the record points to a crew comfortable doing more than just the paint. Confirm the license directly and get a written scope before work starts, standard advice for any small painting outfit that also takes on side carpentry.

I originally hired JustBo Painters to paint one of my rental units after a tenant moved out and before the new tenant moved in. While they were there, they mentioned they could also help with a few other things I needed done. Their team ended up patching holes, hanging cabinets, fixing some plumbing issues, installing two new doors, and changing the locks in addition to the painting. Everyone on their team was professional, easy to work with, and did a great job. I was very happy with the finished product AND price. I’d definitely recommend them!
Jimmy did an excellent job painting our living room walls and ceiling. He went above and beyond to ensure a good result and even threw in some kitchen wall work, too! The work was done quickly and on budget to a very fair price. We would absolutely entrust all of our future painting needs to Justbo.
Jimmy and team painted my entire historical apartment inclusive of 13 foot ceilings, crown, base and louvered doors and some significant patchwork. I am ecstatic with the results; not only does everything look flawless but the team was meticulous in setting up and breaking down and professional in every interaction. They clearly communicated timelines and completed as estimated. I highly recommend JustBo.
Jimmy did a great job when I was in a bind with my kitchen renovation. He acted quickly, communicated really well and everything was completed in a timely manner with very good quality workmanship. Jimmy and team did a wide variety of work: painted ceilings and walls, removal of pot lights, reinstall siding, trim out a window and door, replace hardwood floor boards. He’ll be the first person I call for future work.
I hired justbo painters to repair and paint the front exterior of my mother‘s house. He was clear and upfront about costs and pricing and extremely reasonable. He did a high-quality job at a very good price. I am extremely happy more importantly my mother is extremely happy. I highly recommend them if you need work done on your house
