Services
We provide remodeling and addition solutions tailored to each project's needs, from individual rooms to substantial home expansions. Our process begins by discussing your vision, budget, and space requirements before moving through design, permitting, scheduling, and construction. We also support material selection and design consultation. For larger projects, financing options are available, while formal Change Orders address approved budget or timeline adjustments. 
At JWILCO, we believe finishing details deserve careful attention because they shape the overall impression of a home. Our team can complete finishing work on projects we have remodeled or take over where previous work stopped. Through precise attention to detail, we help create interiors and exteriors that look thoughtfully finished rather than simply marked complete. 
Our kitchen remodeling service transforms outdated layouts into highly functional spaces designed around cooking, entertaining, and family life. We emphasize thoughtful organization, efficient movement, and ample workspace, supported by custom cabinetry and durable countertops. From open-concept reconfigurations to upgraded lighting and utilities, we coordinate the remodeling process, including structural work, permitting, and detailed finish carpentry. 
Our bathroom remodeling services combine everyday functionality with spa-like luxury through carefully planned layouts and quality finishes. We manage renovations from selecting materials through installing the final fixtures, with particular attention to multi-layered waterproofing and high-end tile installations. Our work includes walk-in showers, soaking tubs, tub-to-shower conversions, custom vanities, stone countertops, and comfort upgrades. 
We design and build home additions and ADUs that provide additional space, comfort, and long-term property value. Our work is carefully integrated with existing architecture, including rooflines and exterior finishes. We manage foundations, framing, interior trim, permitting, engineering, and utility coordination. Each project is handled with a clear and organized construction process. 
We create customized building and renovation solutions for projects that do not fit standard remodeling categories. Our capabilities include removing load-bearing walls, expanding entryways, constructing custom decks and covered patios, adding tailored storage, and modifying spaces for improved mobility and comfort. Depending on the project, outdoor materials can range from premium natural woods to durable, low-maintenance composite options. 
A quality paint job begins with thorough surface preparation, and we give that step careful attention. For exterior projects, we pressure wash, scrape, sand, caulk, and prime as necessary before applying premium weather-resistant coatings. Inside, we carefully mask surfaces, use drop cloths, and cut in around trim, ceilings, and fixtures for precise results.

I am very pleased with the work done to install a backsplash in our kitchen. Josh helped me get samples of tile to decide what would look best with our existing materials. Jeremy and others on site showed up on time, worked carefully, and the final result is beautiful. I would recommend this company to anyone!

Josh and crew were wonderful from start to finish. They helped problem solve along the way and never felt rushed. Exceptional craftsmanship and attention to detail. Even ones I wouldnt have noticed. They were on time and worked hard all day. I truly felt like they treated my home as it was theirs. I will not hesitate to call them for my next project!!

Im very impressed and happy with my remodel results from the work that Jeremy and Josh did for me. The bid was accurate and they arrived promptly every morning. Everything was organized well and I always knew what part of the project would be completed next. They checked in with me to see what I thought and asked my opinions when we need to make decisions. I added a few things and that was no problem. They always left my home clean and secure at the end of the day. I own my own real estate firm and I have never experienced this quality of work. I have recommended them to many of my clients and family. They painted the interior, added bead board in two rooms, added board and batten in the foyer and living dining rooms, changed the lighting and mirrors, enclosed my patio and added a storm door. The improvement is remarkable and truly makes my house a home. Below are before and after photos.

I was told about Jwilco by a couple trusted seasoned contractors I know. I am so glad I chose them to do the job. Their work ethic was refreshingly top notch! No extended breaks, no smoking or loud music. They kept me in the loop of findings and progress and treated me with respect. They worked full days & got the project done in a timely and practical way. I appreciate this team and am VERY satisfied with their work! I will refer them to others and call them first in the future! Thank you for your honesty and integrity fellas!
