Rebuilt the floor of my old front porch. Night and day difference! The price was right and they were efficient and tidy. Connor, Zach and their crew were all a pleasure to work with.

Can’t say enough good things about this company and its employees. From the receptionist, to Ryan, Monica, John and Ben, our experience was amazing. Ryan and Monica came out and gave us ideas we never thought about. Ryan’s ideas for the layout of the kitchen, to Monica’s questions about colors and how we wanted the kitchen to feel, made us think. They gave us ideas to think over and time to decide. After a few meetings with Monica, and changes we made, we were ready to begin the project. John and Ben were our team. They came everyday, on time, and explained what they planned for the day. Before they would leave, they explained what they accomplished and what they planned for the next day. We were always kept informed. Ryan would stop by and oversee the project and ask if we had any concerns or questions. And John and Ben made sure everything was cleaned up before they left. Job completed! And we couldn’t be happier. See you at our next project.

Our front porch project is finished. We want to tell you how impressed we were with both Sam and Eli and the work they did on the railing.. They did an exceptional job. They took care to make sure the railing was straight, mounted securely and made sure to tell us what they were doing. When finished the area was cleaned and before they left visited with us to make sure we were pleased with their work. They are an asset to your company. Please be sure and comp[liment them for us on their work. Frank and Pat Riggio

The installers had the window replacement job completed in just a few hours. Zach was great to work with and was price competitive. The process from measurements, placing the window order and installation was flawless.

J&RS has been terrific to work with on three different projects. Clean up and care of property are superb. They pay attention to the smallest details. They have been very responsive to any concerns or issues that may arrise, both during and after the project. They have even willingly consulted on home issues that were not a part of the project. Costs are competitive with other estimates, but material options have been of higher quality.

We had a front porch (8’ x 28’ open gable design) and a small tie-in roof (eyebrow) over the garage added to our home (tie-in roof was previously there however they removed, redesigned, and installed new). Our project manager was Conner and he was awesome (project ran into few snags but he was ready at every turn). Always a text or phone call away through the whole process. The individual (carpenter) assigned to work the project was best described as “attention to detail”. He coordinated with me numerous times on-site to verify he was on the same page as us for the small details. The end product looks amazing and I would hire J&RS again without question. If you want to see the end product contact J&RS.

On a whim I stopped into their office and met designer Nikki. She made me feel instantly Comfortable with the entire process for remodeling my bathroom. The experience w J&RS was top notch. Nikki was great helping me select the finishes. Bailey was a great communicator during the remodel and stopped by several times to assist with questions. And JB the contractor was so nice who does great finishing work! He worked every day (full days!) until the project was done. I can’t say enough about all of these professionals. I am absolutely going to hire them again to do another bathroom and kitchen. HIGHLY recommend!

Common Questions About Home Additions

Most home additions take between 8-16 weeks depending on size and complexity. Second-story additions typically take longer than ground-floor expansions. During your initial consultation, we’ll provide a detailed timeline specific to your project.

For most ground-floor additions, you can remain in your home during construction. For second-story additions, temporary relocation might be necessary during certain phases. Our team works diligently to minimize disruption to your daily life and will discuss the logistics before we start any work.

Our design team specializes in creating seamless transitions between existing structures and new additions. We carefully match architectural details, flooring, and finishes to create a cohesive look that feels like it was always part of your home.

Most additions require building permits, and some may need zoning approvals. As part of our comprehensive service, we handle all permitting processes, including submissions and inspections, making the experience hassle-free for you.

While additions typically increase your property’s value (often returning 50-80% of the investment), they may also affect your property taxes. We can help you understand potential financial implications during the planning phase. Schedule your free consultation today to learn more.
