Basement Remodeling

Unfinished storage becomes everyday living space — guest suites, home gyms, theaters, and hangout spaces built for how you live.

Start your basement
Finished lower-level living space
Overview

Your home's biggest untapped space

That unfinished square footage under your feet can become a guest suite, home gym, theater, office, or all of the above. We start with how your family wants to live, then design a lower level that feels like part of the home — not an afterthought.

Our team handles the full scope in-house: egress and permits, moisture and insulation done right, and finishes that match the rest of your house. Most basement remodels complete in 8–12 weeks of construction with a dedicated project manager.

FAQ

Questions, answered

Something else on your mind? Call us at410-336-7011.

How long does a typical remodel take?+

It depends on scope — most bathrooms run 4–6 weeks of construction, kitchens 6–10, basements 8–12, and additions 3–6 months. You'll get a detailed schedule before we break ground, with daily updates in your client portal.

Do you handle permits and inspections?+

Yes. As a full design-build firm we handle all drawings, permits, and county inspections across Howard, Carroll, Montgomery, and Frederick Counties.

Do we need to move out during the project?+

Rarely. We contain the work area with dust barriers and keep essential spaces functional — most families live comfortably at home through kitchen, bath, and basement remodels.

How does pricing work?+

After an in-home consultation we provide a detailed fixed proposal — design, materials, and construction in one contract. Our Investment Guide shares typical ranges before you even call.

Are you licensed and insured?+

Yes — MHIC 129673, fully insured, and award-winning since 2011, including Baltimore Sun's Best Remodeler 2026.
