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!
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.
