What is bothering you now

When your basement feels too rough to actually use

Maybe you have boxes piled everywhere, a half-finished space, or a room that never quite feels dry or comfortable. These are the situations we are called into most often.

Dark, low-feeling rooms

Low ceilings, poor lighting, and mismatched finishes make the basement feel more like a storage locker than part of your home.

Cold floors and damp corners

Concrete underfoot, drafty walls, or past moisture issues make it hard to relax, let kids play, or invite guests to stay.

Choppy layouts and wasted space

Random walls, awkward bulkheads, and scattered storage mean you lose square footage you are paying to heat and cool.

Starts and stops with other contractors

Work begins, stalls, or changes direction, leaving you with exposed framing, dust, and no clear completion date.

Our fix: A scoped, sequenced basement plan with protection, rough-ins, finishes, and inspections mapped out from day one so you know what is happening next and when you get your space back.

We start with how you want to live in the space, then design, phase, and build around that so every decision—walls, flooring, lighting, and storage—supports that plan.

    Punch list and handoff

    We walk the basement with you, handle touch-ups, confirm everything works as it should, and leave behind simple care notes.

Key decisions

Basement finishing choices that change how the space feels

We walk you through the few decisions that matter most so you are not overwhelmed by options or stuck with finishes you regret.

In our planning meeting we look at how you live, how much natural light you have, and whether this is for family, guests, or rental—then narrow your choices to combinations that make sense.

  • How you will use it

    Layout and zones

    When this is best

    Ideal if you need a mix of open space and private rooms.

    Key details

    • Plan where TV, play, office, storage, and guest areas belong
    • Align bulkheads, doors, and walls so everything feels intentional
    • Allow for future changes like adding a bedroom or bathroom
  • Comfort underfoot

    Flooring package

    When this is best

    Best if you want a warm, durable floor that still respects basement conditions.

    Key details

    • Options like luxury vinyl plank, engineered wood, or carpet tiles
    • Moisture-aware underlayments to keep things feeling dry
    • Transition details that tie into main-floor finishes
  • Brightness and height

    Ceiling and lighting

    When this is best

    Right when your basement feels low, dark, or full of bulkheads.

    Key details

    • Recessed, low-profile lighting that brightens without reducing headroom
    • Smooth drywall or upgraded drop ceilings depending on access needs
    • Lighting zones for TV, work, and play areas
  • Everyday function

    Storage and built-ins

    When this is best

    Perfect if you want toys, gear, or seasonal items hidden but reachable.

    Key details

    • Built-in shelving or closed storage along long walls
    • Closets sized for seasonal bins and household overflow
    • Design that keeps mechanical areas accessible but less visible

What moves pricing

What changes the cost of finishing your basement

We walk you through these factors during the consult so you understand why one option costs more or less than another.

Existing conditions and repairs

Moisture problems, old framing, or unsafe electrical need attention before we invest in new finishes.

Rough-in and layout changes

Adding or moving bathrooms, laundry, or walls affects both cost and timing, especially in older basements.

Finish level and materials

Standard, durable finishes keep budgets predictable, while premium millwork, tile, and fixtures increase investment.

Access and staging

Tight stairs, limited parking, and condo or townhouse rules can change how quickly we can move materials and waste.

Phasing and scheduling needs

Working around tenants, home offices, or strict quiet hours can extend timelines and site visits.

Before we start, we review these factors with you, price them in plain language, and flag any that are optional versus must-do.

Guarantees that make basement finishing feel manageable

Clear scope and written plan

You see exactly what is included, what is not, and how we handle surprises before any work starts.

Realistic schedule and milestones

We outline key dates for framing, rough-ins, inspections, and finishes so you know when each stage is happening.

Protection for the rest of your home

We protect floors and walls on the way to the basement, manage dust, and reset pathways at the end of each day.

Communication you do not have to chase

You have a single point of contact, daily check-ins while work is active, and quick answers if plans need to adjust.

2-year workmanship warranty

If something related to our installation fails under normal use, we return to investigate and make it right.

The aim is not just a nicer basement—it is a smooth project that leaves you with livable space and no unresolved loose ends.

Preparation

How to prep for a smoother basement project

A few small steps before we start make the work go faster, protect your belongings, and keep your schedule predictable.

  • Clear or group personal items in the basement so we have open access to the areas being finished.
  • Flag any past leaks, foundation cracks, or electrical issues you are aware of so we can inspect them early.
  • Confirm where crews should park, which entry to use, and any building rules we need to follow.
  • Let us know about kids, pets, or work-from-home schedules so we can plan noisy work accordingly.
  • Decide who will make final decisions on layout and finishes so approvals stay simple once we start.

When finishing your basement should wait

Sometimes pausing the project first protects your budget and the long-term result.

Active water or structural issues

What usually happens

Covering up leaks or structural problems leads to damaged finishes and repeated repairs.
Our fix
We help you address foundation, drainage, or structural concerns first, then return to build on a stable, dry shell.

Unclear goals or decision makers

What usually happens

Changing the plan midstream adds cost, delays inspections, and frustrates everyone involved.
Our fix
We spend extra time up front aligning on how you want to use the space and who signs off on changes before we order materials.

Deadlines that fight with quality

What usually happens

Rushing cure times or inspections can lead to callbacks, squeaks, or uneven finishes.
Our fix
We will be honest about what is realistic, suggest phasing where it makes sense, and only take on the work if we can do it properly.

Basement finishing questions homeowners ask us most

Straight answers about timelines, disruptions, and what we handle for you.

1
How long does basement finishing usually take?
Most projects take 4–10 weeks from start of on-site work, depending on size, rough-in needs, and finish level. We will give you a tailored range after seeing the space.
2
Will we be able to use the rest of the house?
Yes. We plan noisy and dusty work in blocks, protect main-floor paths, and keep bathrooms and kitchens accessible. You will always know which areas are impacted and when.
3
Do you handle permits and inspections?
If permits are required, we can help coordinate drawings, applications, and inspections, or work alongside your designer or engineer—whatever fits your project best.
4
What if you find issues behind the walls?
If we uncover surprises like moisture, unsafe wiring, or structural concerns, we stop, show you the issue, explain options in plain language, and price any changes before continuing.
5
Is there a warranty on the work?
Yes. Our basement finishing work includes a 2-year workmanship warranty. If something we installed fails under normal use, we return to investigate and address it.

Working with KDM has been a complete pleasure. The entire team was friendly, prompt, efficient, and thorough. They under promised and over delivered. I got a beautiful basement that I am completely happy with in a timeframe that was barely an inconvenience. They cleaned before, during, and after so it was easy to move into the space.
