Services
Our home remodeling and addition services are built around thoughtful planning and dependable execution. We guide projects from initial consultation through design, permitting, scheduling, and construction, maintaining clear communication throughout. Whether you need a single-room renovation or a larger addition, we provide skilled workmanship and straightforward project management. Our work includes kitchens, bathrooms, living spaces, ADUs, and more. 
We approach every finish carpentry detail with the same level of care we bring to a complete remodel. Whether we are completing our own project or finishing work begun by someone else, our goal is to create results that feel deliberate and refined. Quality finishing transforms a house from merely completed into a home that feels genuinely cared for. 
We specialize in comprehensive kitchen renovations that improve both functionality and appearance. Custom or semi-custom cabinetry can provide soft-close hinges, pull-out pantries, and smart organization, while quartz, granite, or quartzite countertops offer durable surfaces. Open layouts, task-focused lighting, modern appliance circuits, and custom tile backsplashes further support a kitchen designed for everyday living and entertaining. 
We provide comprehensive bathroom renovations designed to create attractive, comfortable spaces that remain functional for daily use. Proper waterproofing is a central part of our approach, helping protect custom tile, tubs, and showers from moisture-related damage. From compact powder rooms to master bathrooms, we coordinate plumbing, electrical work, permitting, tile, fixtures, vanities, lighting, heating, and ventilation. 
Our home addition services help families expand their living space as their needs and lifestyles change. We create additions that complement the original structure through carefully matched roofing, siding, windows, and interior details. From foundation work through finishing, we oversee construction while coordinating permitting, structural engineering, and utilities. ADUs and multiple addition styles are also available. 
We provide tailored building, carpentry, and renovation solutions for homeowners whose ideas require more than standard remodeling. Our team works directly with you from the initial concept through construction, addressing specialized layouts and custom features with creative problem-solving and precise craftsmanship. We handle engineering, permitting, and finish carpentry while maintaining a strong commitment to lasting results. 
We provide professional interior and exterior painting with careful preparation and durable finishes. Our process includes pressure washing, scraping, sanding, caulking, and priming where needed to establish a strong foundation. We use premium, weather-resistant paints and primers, while protecting interior surfaces and creating clean lines around trim, ceilings, and fixtures.

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!

We had an amazing experience with JWILCO Construction during our home remodel. From the very beginning, we trusted their expertise, and they absolutely delivered. Their knowledge, attention to detail, and professionalism made the entire process smooth and stress-free.
The quality of the work is outstanding, and the final result exceeded our expectations. Its clear they take pride in what they do. Were so glad we chose them and would highly recommend them to anyone looking for a reliable and skilled contractor.

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!

JWILCO was an amazing company to work with. They did a total and complete siding job with James Hardie siding on our 1968 home.
They worked diligently and thoroughly, arriving punctually and consistently every morning of the job. It was obvious that they took great care in the entirety of the work that they did. I was highly impressed.
Best contractor experience ever!!
