"My husband and I are over the moon with the work Krugh Custom Services preformed at our house. We needed dry wall and painting done. Every employee showed up on time and proceeded professionally. They went above and beyond to ensure our house stayed clean while they were performing their work. After the work was finished Dave the owner called to ensure we were pleased with the work of his team. We will be needing the outside of our house painted in the next few month and we will for sure being hiring Krugh Custom Services for that job as well. Couldn't recommend this company enough!"
