We combine design planning with construction expertise and keep homeowners informed throughout the work. Services include kitchens, bathrooms, bedrooms, living areas, ADUs, in-law suites, garage conversions, patios, decks, laundry rooms, mudrooms, and load-bearing wall work, supported by consistent crews and strong craftsmanship.

Kitchen Remodeling Kitchen Remodeling

Our full-scale kitchen remodeling service is designed to replace outdated spaces with kitchens that support daily cooking, entertaining, and family activities. We carefully address workflow, storage, and workspace while using premium materials built for everyday demands. Depending on the project, we handle layout changes, cabinetry, countertops, lighting, utility rerouting, permitting, and fine finish carpentry.

Bathroom Remodeling Bathroom Remodeling

We handle bathroom remodeling projects from the initial selection of materials through completion and final fixture installation. Every renovation receives careful attention to waterproofing systems and high-quality tile work to help prevent hidden leaks, water damage, and mold growth. Whether updating a compact powder room or extensively renovating a master bath, we coordinate the necessary work and finishing details.

Home Additions Home Additions

When additional living space is needed, we build solutions designed to integrate naturally with the existing home. Matching architectural elements, rooflines, siding, windows, and trim helps each addition appear consistent with the original structure. We also handle complex framing, foundations, permits, engineering, and utility integration. Our offerings include living areas, bedrooms, master suites, ADUs, garages, and bonus spaces.

Interior & Exterior Painting Interior & Exterior Painting

Our interior and exterior painting services combine meticulous preparation with high-quality materials for lasting results. Interior work includes filling holes, sanding rough areas, masking, and protecting floors and trim. Exterior preparation involves pressure washing, removing loose paint, caulking gaps, and priming raw wood. We apply durable finishes using professional techniques.

Custom Construction Custom Construction

Our approach to custom construction begins with your vision and continues through every stage of the build. Standard blueprints are not required to begin; photos, rough sketches, and inspiration can provide the starting point. We then address the necessary engineering, permitting, structural modifications, finish carpentry, and specialized features to create a carefully integrated result that reflects your original ideas.

Custom Finish Carpentry Custom Finish Carpentry

Finish work is where the quality of a project becomes especially visible, so we give each detail our full attention. We provide finishing services for our own remodeling projects as well as work left incomplete by others. Our focus is on achieving a polished appearance that makes the home feel cared for and clearly finished the right way.

We love our new Primary Bathroom remodel! Superb craftsmanship, professional workers, and first rate customer service make for a top tier Company. Would highly recommend Josh and Team to anyone!

JWILCO was a pleasure to work with! Business Manager, Josh Jones worked very hard to give me a beautiful & functional bathroom, within my budget! His crew of Jeremy, Samuel & Tobias were always on time, courteous, respectful & left our bathroom clean during remodel, for us to still get to our master closet on the daily! It is hard to find contractors now days that feel your time is just as valuable as theirs! Josh always called when he said he would, & returned my calls in a very timely manner. That is very rare now days, & I am very appreciative! I love my new bathroom & would not hesitate to use them for future remodeling!

Its honestly a little scary taking on a big project like re-siding your house, but Josh and his crew made the whole experience so much easier. From the start, we felt like we could truly trust themand that means everything.

They showed up and worked hard every single day, rain or shine, and did an amazing job. Not only are they skilled, but theyre also kind, honest, and just great people to work with. Were so thankful and would absolutely recommend them!

We hired JWilco to do a complete remodel on our primary bathroom and we couldn't be happier. The project included a custom tile shower, modern freestanding tub, vanity with solid countertops, vessel sinks, tile heated floors, custom wood shelves, and ceiling soffit rebuild. Steve, the project lead, was easy to work with and communicated with both of us every step of the way. He made sure our vision came alive. Their workmanship was exemplary, detailed, professional and they always strived for perfection. The tile work on both the custom shower and the floor were masterful. There was an issue with grout that was not an easy fix. Steve assured us that it was his problem to solve and he worked through several solutions to end up with an impressive outcome. They were very respectful of our time, agreeing at the last minute to postpone the project one week due to a family emergency. Their bid was competitive and what we expected for a project of this scope and size. We will use JWilco again. We highly recommend them for any of your remodeling needs.

JWILCO and his team did an excellent job taking care of my clients new driveway. I highly recommend them!

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!!

JWILCO did a bunch of work on my house. I had to completely replace the siding on one side of my home from woodpecker damage, roof cleaning and shingle repair, chimney repair, high-risk exterior painting and door frame repairs. Jeremy at JWILCO did timely, professional, and quality work at a fair and reasonable price. My neighbors were so impressed, they had him work on their homes as well. Give JWILCO a call if you need work done. You'll be thankful you did!

Working with JWILCO was a great experience. They finished the job in less time than expected with great attention to detail. I had little ones in the home with me while they were working and the crew was very respectful. I do recommend them.

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!
