An unfinished basement is one of the most overlooked sources of usable square footage in a home, and often one of the most cost-effective ways to add real living space without the cost of building an addition.
Mulberry Builders performs basement remodeling for Lexington-area homeowners at every stage, from an unfinished, damp space that needs waterproofing before anything else can happen, to a basement that’s ready to become a family room, home office, guest suite, or full in-law living space. Every project starts with an honest assessment of your basement’s current condition, since what’s happening behind the walls matters just as much as what the finished space will look like.
Before any finishing work begins, we assess and address moisture issues, since finishing a basement that isn’t properly waterproofed leads to mold, damage, and costly rework down the line. A basement that isn’t properly waterproofed will eventually show it, no matter how well the finishing work is done, which is why any real basement remodeling process starts with an honest look at moisture and drainage, not just a conversation about paint colors and flooring.
Once your basement is ready, our team performs the full range of basement finishing work: framing, insulation, drywall, flooring, electrical, and lighting, all brought up to current code. For basements that are already finished but outdated, damaged, or no longer working for how your household actually uses the space, we handle full renovations too.
We build out family rooms, home offices, home theaters, guest suites, and full in-law living spaces with a bedroom, bathroom, and kitchenette, all built around your specific goals for the space. If your plans include a basement bedroom, we’ll also handle the egress window it requires, and honestly, it’s often a smart addition even when it’s not strictly required, since it improves natural light and gives you a safe secondary exit.
A few signs your basement may need waterproofing before finishing: visible water stains or efflorescence (that white, chalky residue) on foundation walls, a musty smell that doesn’t go away with ventilation, visible cracks in the foundation, or standing water and dampness after heavy rain.
Contact us today to get started. Together, we will explore your options to find a solution that meets your needs and budget.
Every basement remodel starts with a free on-site assessment, where we evaluate your basement’s current condition, including any moisture or structural issues, before we ever talk design. If waterproofing is needed, that gets handled first, finishing over an unresolved water problem is one of the most common and costly mistakes in basement remodeling, and it’s not one we’re willing to make on your behalf.
From there, you decide how the space will function, family room, bedroom, home office, or a full custom suite, and we design around it. We handle the permit process anything specific to basement bedrooms or egress windows. Construction covers framing, insulation, electrical, plumbing where needed, drywall, and flooring, all on a clear project timeline, and we walk the finished space with you before we consider the project complete.
We’re more than basement contractors, we’re your neighbors, and we understand that home projects like this are a big investment. Whether you’re finishing your basement to add real living space or turning it into an in-law suite, we’re proud to offer a variety of financing options to help make your project more affordable.

How much does basement waterproofing cost?
Waterproofing typically adds somewhere between $3 and $10 per square foot depending on the method required, and it’s a cost worth planning for upfront rather than discovering mid-project.
Do I need a permit to finish my basement?
In most cases, yes, particularly for any project that includes electrical, plumbing, or adding a bedroom. Basement bedrooms specifically have additional code requirements, including egress windows, that need to be accounted for during planning, not discovered during inspection.
Can any basement be turned into a bedroom?
Only if it meets code requirements for a legal bedroom, which typically includes a window that meets minimum egress size requirements, a closet, and a door.
How long does it take to finish a basement?
The Timeline depends heavily on scope, though 1 to 4 months. A basic finish on a dry, code-ready basement can move relatively quickly, while a project requiring waterproofing, an egress window, or a full bathroom addition takes considerably longer.
Is finishing a basement a good investment?
Yes, for most homeowners. A finished basement adds genuinely usable living space at a lower cost per square foot than building an above-grade addition, since you’re working within the home’s existing footprint rather than expanding it.
