Along with the Monk's Kitchen & Bath Design Studio, we are a full-service home improvement provider. Monk's will help you plan, design, and purchase everything you need for a remodel. Then our expert craftsmen will install everything and our painters will come and complete the job.

"If you are a perfectionist and demand the best in yourself and others, you need look no further than this incredible company. From start to finish, there is no detail left unattended. My project was far from the easiest because I did not want to replace my cabinets. Several people on the Monk's team said that I would have been crazy to do so. There were other limitations within which whoever undertook the job would have to work as well. Most contractors will not touch a project unless they can gut the entire space and start from scratch. From the beginning, Monk's was willing to treat me as a contributing member of the team. I am a very hands on person and always love learning from each trade that contributes to the final project. From Maria who does the initial interview and measuring to Greg, who comes up with numbers to the penny to sell the job, to Garrett, my project manager to the counter templaters, installers, Monk designers, and consultants, there is nothing and no one I would have changed. My kitchen has been given new life, and I am ecstatic every time I look at the results."
