If it has to do with walls or ceilings - we do and do it well. From frame to finish. Check out our web site to see examples of our work : www.charliesdrywallandpainting.com Hear what our customers are saying and contact us to come and see you project.
"After dealing with many disappointing contractors/handymen, Charlie & Richard were a (shocking) breath of fresh air and worth every penny. This company takes pride in their work and these two men truly want to do the best job for their customers in the long run. They do not cut corners at all and have extreme attention to detail. From the beginning, Charlie was organized, responsive and detailed in his quote. Over the course of 2 weeks, Richard and Charlie were consistently punctual and took great care to be respectful of our home (always used drop cloths everywhere they walked, swept/cleaned up after themselves daily & used the proper machines/filters so dust wouldn’t end up all over our house). The painting and drywall repair came out beautiful! I only wish I found this company sooner, but we will definitely be hiring Charlie & Richard again!"
