Basement Remodeling planned for how Glen Ellyn homeowners live.
Glen Ellyn’s charm sits partly underground. The village is full of vintage character homes set on mature, tree-shaded lots, and those older foundations have spent decades dealing with clay soil, heavy canopy, and grading that has shifted over time. Before a single stud goes up in a basement like this, the question worth answering is where the water goes.
We look for the tells first: efflorescence on the block, a tide line on the slab, a sump that runs hard after every storm, a downspout dumping against the wall. Interior drainage, a reliable sump with backup, vapor management at the walls, and corrected grading outside form the dry shell that everything else depends on. Finishing over a damp foundation just buries the problem inside the wall cavity, and on a home with this much history that is a costly mistake to undo.
Once the space is genuinely dry, the original character of the house can carry through downstairs in the finishes and trim. As a small family crew, we would rather spend an extra day chasing the water than hand you a beautiful room that smells like a basement by spring.

Have a different question? Ask during your free estimate →-
How much does a typical kitchen or bathroom remodel cost?
Bathroom remodels in our area typically run $18,000–$45,000. Mid-range kitchens are usually $35,000–$80,000 — full custom kitchens can reach $120,000+. We give you a detailed estimate in writing after the in-home visit, so you see the numbers line by line before signing anything.
-
How long will my project take?
A bathroom is usually 3–5 weeks from demo to final walkthrough. A standard kitchen runs 6–8 weeks. Basement finishes are 5–8 weeks. We give you a written schedule before we start — and because we use our own in-house crew, we don't lose days waiting on a subcontractor to show up.
-
Do you handle the permits and inspections?
Yes — every time. We pull the permits, schedule the inspections, and meet with the inspectors. You don't deal with the village. We handle Buffalo Grove, Arlington Heights, Lombard, Glen Ellyn, Wheaton, and the rest of our service area.
-
Can we live in the house during the remodel?
Almost always, yes. We seal off the work zone with plastic, set up a temporary kitchen if we're remodeling yours, vacuum daily, and do a deep clean at the end. Most clients stay in the home for the full project — we plan the sequence around your daily life.
-
How do payments work?
A small deposit at signing, then progress payments tied to milestones (rough-in complete, drywall complete, final walkthrough). You never pre-pay for work that hasn't started. Final payment is only released after you sign off on the final walkthrough — not before.
