"I was most impressed with Jason and his crew. Besides being very personable, they clearly know their stuff. The work was finished on time, budget appropriate, and every night I came home to a totally cleaned-up area. The quality of the work was excellent despite having at the last minute to change and revise our plans for the week. Jason was very communicative in learning about our needs and meeting them. It was a fully positive experience and I would not hesitate to use them again."

"Hunter and his team finished my basement. They were always prompt, professional and friendly. They were able to start my project within a couple of weeks and was completed in a very timely manner. The project was coordinated and managed very well, there was rarely a day of no activity. Hunter was easy to communicate with and very responsive, knowledgeable, and flexible. The workers were knowledgeable and took pride in their work. The pricing was very reasonable and the result was high quality. Great experience. I highly recommend Tradesman Construction."

"We needed our free-standing shower replaced. This included replacement of some tile outside the shower, and cosmetic repair of part of a wall in our bedroom. Big bathroom contractors like Luxury Bath told us we would have to get separate contractors for each of those projects. Bob took care of everything. In addition, it turned out that our shower was not a standard size and required a custom design. Bob handled this as well. Due to this, the project lasted longer than initially expected as the shower glass had to be specially ordered. However, we now have a rain-drop glass shower with rain shower head and hand-held sprayer that blends in with our existing master bath. Bob's tile work is beautiful. We got the shelf in the shower we wanted as well as our choice of tile and design (Bob met me at a tile store of my choosing to pick out the tiles for the entire project). Importantly, Bob kept within the budget agreed upon. He consulted with us throughout the project so we were always aware of where things stood and understood when the project was delayed."

"The pro was very communicative, able to adapt to my schedule and provided the exact work requested in a timely professional manner. It was very humid the day of install and they made a return trip to make sure everything dried and sealed appropriately."

"????? We couldn?t be happier with the basement finishing project completed by Millstone & Co LLC! From start to finish, the team was professional, detail-oriented, and committed to delivering quality craftsmanship. They transformed our unfinished basement into a beautiful, functional living space that feels like a natural extension of our home. Communication was great throughout the process, and the attention to detail really showed in the finished product. If you?re looking for a reliable contractor who takes pride in their work and genuinely cares about the results, we highly recommend Millstone & Co LLC. We would absolutely work with them again on future projects!"

FAQs for addition to existing structure building service projects in York, PA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
