Reviews
KOSO Drywall did an amazing job with my basement. I was at ease throughout the whole process as they finished the job in 7 days as agreed including delivery of the material, install drywall, taping/mudding and sanding. Would definitely go to them in the future as well as recommend them to family and friends.
I recently hired Koso drywall to complete a drywall project where we divided the upstairs from the downstairs with a raised/high section, and I couldn’t be happier with the results. The quality of the work was excellent everything was done with great attention to detail and turned out exactly how I envisioned. The team was professional, very clean, and respectful throughout the entire process. They made sure to keep the workspace tidy and left everything in great condition once the job was finished. I would highly recommend them to anyone looking for quality drywall work done right.
Koso drywall delivered outstanding work from start to finish. Its amazing how skillfully they repaired the mess left behind by a previous contractor. The team was efficient, precise and committed to doing the job properly. Every seam, corner, and finish looked clean and professional and also they took the time to ensure the final result was flawless. This was a rare find. Will 100% be contacting them again for future jobs.
LOL these days if someone shows up its a wonder but these guys show up early and get the work done, and actually Well done. Second time use this crew, All just good guys, all work done very well! One day all drywall installed, 3 days all plaster done and sanded. Thank you,
Had Koso Drywall do the drywall in my basement and I’m very happy with the results. The work was clean, professional, and the finishing was done really well. They were reliable, paid attention to the details, and left everything looking great. I would definitely recommend Koso Drywall to anyone looking for quality drywall work.
