Manager Patil Orthodontics5 StarI am the office manager of a company that recently had the pleasure of working with Jim Black Construction. I can’t say enough good things about our experience. Our project was complex, with many moving parts and significant insurance hurdles. The JB Construction team went above and beyond—doing everything possible short of writing the check themselves—to help us secure the approvals we needed. I have no doubt that most other companies would have given up, but JB Construction rallied around us, found solutions, and ultimately delivered an outstanding finished product.
From our very first interaction with Erick, to the support from Jim C. and Sky, we always felt informed and cared for. The office staff patiently walked us through every step, making sure we understood the process before construction even began. Angela, their talented designer, was incredibly patient and helpful as we made our selections. Even the accounting team was a delight to work with.
The professionalism, dedication, and genuine care shown by everyone at Jim Black Construction made a stressful process so much easier. Thank you, JB Construction, for your exceptional service from start to finish. We couldn’t have done it without you, and we highly recommend your company to anyone seeking top-notch results.

Anne Calkins5 StarJim Black Construction did an amazing job repairing our basement from damage caused by a pipe back up. All the crews were on time, did great work and were very pleasant to work with. The time lines were true and communication between Brian and us was so helpful.
I highly recommend Jim Black Construction!Saturday 24th January 2026
Christina Pacheco1 StarUsing this company has been an absolute nightmare from beginning to end! If you value your home, your time and your sanity I cannot recommend enough that you absolutely do NOT use this company! I seriously cannot believe they are even in business. They are completely unprofessional and do terrible, sloppy, subpar work. They have absolutely no attention to detail and have messed up every single thing they have done to my home, in addition to causing additional damage to my home including; gouges to my walls, scratches to my bathtub, broke my towel rod, chipped my tile, mortar and drywall plaster poured out on my front porch, pavers, yard decor and decorative rocks in my yard, broke my pantry, removed my window screen and bent it and then left it on the bushes in my front yard to run their power cord, and chipped my furniture in several places.Their drywall work, and painting are abysmal! Their painters missed several places and also got paint all over the new tile floors and hardwood. The drywall texture they applied was no where close to the existing texture. They did not wipe off the baseboards from the construction dust before caulking them so the caulking immediately began peeling off the same day. Their hardwood flooring people are horrible! They did not pattern the wood they laid, left holes/gaps and gouges in the flooring around the doorframes, installed split pieces of new hardwood and had green wood glue coming through between the boards. Worse yet, they did not put two coats of shiny oil-based polyurethane on the hardwood, as agreed to numerous times both orally and in writing. Instead, they took it upon themselves to use a matte water-based sealer that is not water resistant or scratch resistant and it looks dull and unfinished. Now everything has to be moved out of my house and the floors redone a second time. Due to their incompetence, I have also endured diminished value to my home due to having my hardwood floors sanded 2 additional times. Then they had the nerve to tell me I should pack and move the boxes myself and they would only move the furniture the second go round, despite this being 100% their fault and causing me huge inconvenience and costing me several more days of my time. They told me that I should pack the boxes myself knowing I had neck surgery 2 weeks prior. They could not even install a sink vanity or a countertop straight. After 2 failed attempts, I had someone else finally do it instead. They installed the wrong tile in one of the bathrooms and made me pay a different contractor to rip it up and reinstall the correct tile. I was told "it is not their job to ask questions" as to which tile was supposed to be used there. Their bathroom remodeler also put nothing down to protect the new hardwood floors and left mortar stains on them. Their "final clean" was an absolute joke! They left thick layers of dust, chunks of remodel debris all over the bathrooms, wax from the wax toilet ring stuck to the shower floor, and I kid you not, dead flies! I literally had to spend 3 hours cleaning the bathrooms myself after they left. When you bring issues to their attention to are met with completely unprofessional, rude, defensive attitude and denials if they bother to respond. I have completely remodeled 4 homes in the last 8 years and have never had a single issue like this with a contractor, yet alone had problems like this with absolutely every single thing done. I used this company as they were on my insurance's preferred contractor list after my home flooded in February and it was a huge mistake. Note, the majority of these photos ARE what this company thinks is acceptable, finished work, despite the owner's reply to my review. This was their completed painting, drywall and final clean ect. I had to finish the painting and cleaning myself. It is ridiculous to act like they are being generous to redo what they messed up without charging extra! Also, they addressed absolutely no additional items that were not their responsibility. Please stay away from this horrible company!Wednesday 30th July 2025
Faith Warner5 StarAfter experiencing a house fire, I hired Jim Black as my contractor, and I couldn’t be more pleased with the outcome. From cleaning to construction and restoration, every member of their team was exceptional. The quality of their work was outstanding, and they consistently went above and beyond to ensure everything was completed to my satisfaction. They were always available to answer my many questions, and their responsiveness made a difficult time much easier. I highly recommend Jim Black for anyone in need of reliable and professional restoration services.Wednesday 8th October 2025
Shelly Maye5 StarThe most important thing for me is communication and the team at Jim Black did that. The Project Manager Cristin and the General Contractor Donovan made the fire recovery so much easier.
After the initial inspection, I felt confident that my home was in good hands.
During the work phase they cheked everything to make sure that the fire/smoke damage was completely mitigated under the siding and eaves. Top quality work.
Thank you Jim Black, and thank you Cristin and Donovan!Friday 17th January 2025
