We provide full-scale kitchen remodeling focused on creating functional, beautiful spaces tailored to your culinary workflow. Our approach prioritizes traffic flow, storage, and counter workspace while incorporating durable materials such as solid wood cabinetry, quartz or granite surfaces, and luxury flooring. We also manage structural changes, utility rerouting, permitting, and fine finish carpentry throughout the project.
We transform bathrooms into comfortable, functional retreats through custom tile work, modern fixtures, and intelligent layouts. Our full-service renovations cover material selection, plumbing, electrical work, permitting, waterproofing, fixture installation, and finishing touches. We specialize in custom-tiled walk-in showers, premium tubs, tailored vanities, stone tops, radiant heating, efficient fixtures, and advanced ventilation systems.
We create seamless home extensions and Accessory Dwelling Units that increase usable square footage without compromising the character of the existing home. Our services include multi-room and second-story additions, master suite conversions, ADUs, and garage or bonus room expansions. We coordinate the construction process from foundation and framing to interior finishes. Permitting and engineering are managed as well.
Our custom construction service transforms distinctive ideas into structurally sound realities through flexible design and specialized craftsmanship. You can bring rough sketches, photos, or Pinterest inspiration, and we collaborate with you throughout the building process. From altering structural layouts to creating custom built-ins, outdoor structures, and accessibility upgrades, we approach each project with precision and attention to longevity.
We deliver smooth, lasting interior and exterior paint finishes through disciplined preparation and professional application. Premium paints and primers are selected for durability and resistance to moisture and UV exposure. Depending on the surface, our preparation may include sanding, scraping, pressure washing, caulking, and priming, followed by carefully applied finish coats.

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.

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.

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!!

If your looking for contractor to remodel, repair, restore your home choose JWILCO Construction!!
We recently had a kitchen sink water supply line break and flood entire 1st floor. Filed insurance claim requiring water mitigation and restoration repair. After water mitigation was completed, entire flooring, trim, kitchen cabinets, paint, dry wall, plumbing and electrical repair was needed to put home back together. JWILCO was highly recommended by friends and choosing them was the best decision ever. Restoring entire 1st floor appeared to be daunting but JWILCO crew timely and professionally restored home beautifully... Josh, Jeremy, Sam and the rest of crew were awesome. The entire job took about 2 and half weeks and the crew started work promptly everyday at 8am and worked tirelessly until 5pm. Jeremy the foreman was such a knowledgeable, highly skilled craftsman and extremely patient answering every dumb question, concern I had. Had difficulty with insurance adjustor getting a fair claim reimbursement and Josh (the owner) diligently worked with adjustor explaining repair details, cost and other factors which was an enormous help. So if your looking for a contracting company that's honest, prompt, highly skilled and great customer service go with JWILCO.
