An unfinished basement is square footage you're already paying for and not using. Whether you need a rec room, home office, guest suite, or rental unit, finishing it right means solving the problems most homeowners don't think about until it's too late — moisture, egress, ventilation, and code-compliant electrical.
J. Jensen Enterprises finishes basements the way we'd want ours finished: dry, code-compliant, and built to actually last in a below-grade space.
What we handle:
- Moisture assessment and waterproofing before any framing begins
- Framing, insulation, and drywall
- Egress window installation for code compliance
- Electrical and lighting layout
- Flooring suited for below-grade conditions
- Bathroom and wet-bar rough-in and finish
- Permit coordination and inspection
Why it matters: Basements fail differently than the rest of the house. A finish that looks great on day one can hide a moisture problem that ruins it by year three. We evaluate the space before we finish it — not just how it will look, but how it will hold up — so you're not paying twice for the same room.
Justin and his team were there for us every step of the way from the start of a big leak to the repair and upgrade since they were already here!
J. Jensen came out at last minute and removed a wall and installed a beam during a kitchen remodel. I am around new construction builds all the time. He has the quality of someone building $1,000,000 homes!
We hired Justin to remodel our guest/kids bathroom, and they did an absolutely first-class job! The entire project was completed in a timely manner, and the results exceeded our expectations. What stood out most was their quality craftsmanship and attention to detail, every part of the remodel was done with care and precision. Justin and his crew were professional, reliable, and easy to work with throughout the entire process. We’re thrilled with how everything turned out and are already excited to start our next project with him and his team. I would highly recommend Justin to anyone looking for top quality work!
The J. Jensen team was very knowledgeable and professional. The work was done in a timely manner. The job site was cleaned up daily. We are very pleased with the experience and the final product.
Justin and his team renovated my master bathroom giving us a high quality update. He is always pleasant, patient and professional working with us. One example I'd like to highlight is with a part of our initial shower wall panel installation which looked acceptable to me. His team thought it was not aligned enough and redid their work to make it perfect. This shows that he wanted their remodeling projects to be so good that I would recommend them to others so I am doing so!
