Interior remodeling is the connective work that makes a house feel finished: flooring that runs continuously, trim and doors that match, a staircase that is no longer the oldest-looking thing in the entry, and lighting that suits how the rooms are used. It is also the most common companion to a kitchen or bathroom project, because a remodelled room that stops at a threshold draws attention to everything around it. Luma House scopes interior work so the whole floor reads as one decision.
What this service covers
Interior work covers the surfaces and the millwork rather than the mechanical core of a house.
- Hardwood flooring: new installation, replacement, or refinishing where the existing floor has life left
- Transitions between materials, and running one floor through rooms that were previously carpeted separately
- Millwork: baseboards, casings, crown, wainscot, coffered and beamed ceilings, built-in cabinetry and shelving
- Staircases: treads, risers, newels, balusters and handrails, including replacing dated spindle systems
- Interior doors and hardware, including resizing openings and adding cased openings
- Fireplace surrounds and mantels
- Lighting layouts, switching, dimming and the electrical work to support them
- Removing or reframing non-structural walls, and the drywall and paint to finish
Problems Duluth homeowners bring us
Interior enquiries usually come from mismatch rather than failure.
- Carpet in some rooms and hardwood in others, with a different species in the entry
- Builder-grade trim and hollow doors in a house that has otherwise been upgraded
- An oak-and-white spindle staircase that dates the entire front of the house
- One ceiling fixture per room and no dimming anywhere
- A wall that makes the main floor feel like four small rooms
- A fireplace wall that is the visual centre of the room and the weakest detail in it
Planning the project
Interior work is mostly about sequence and dust control.
- Decide the extent: which rooms, and where every material change will land
- Check the existing floor, subfloor flatness and any level changes between rooms
- Confirm whether any wall under consideration is load bearing before it is on a plan
- Choose the trim profile and door style first, since everything else is detailed around it
- Plan the lighting and switching before ceilings are closed
- Agree whether the household stays in place, which decides phasing and containment
- Agree a written scope, schedule and change-order process
What drives the budget
Interior budgets are driven by area and by detail. Flooring and paint scale with square footage fairly predictably. Millwork scales with linear footage and with how many inside and outside corners the profile has to turn. Staircases and built-ins are the items most often underestimated, because both are essentially custom cabinetry installed in a space that is rarely square. Refinishing an existing hardwood floor, where the floor allows it, is usually the single highest-impact item per dollar in an interior scope.
| Factor | Lower-cost end | Higher-cost end |
|---|---|---|
| Layout | Same footprint, fixtures stay put | Walls, plumbing or venting move |
| Structure | No structural changes | Beams, foundations or roof tie-ins |
| Finishes | Stock or semi-custom selections | Custom cabinetry, natural stone |
| Systems | Existing electrical and HVAC are adequate | Panel upgrades, new circuits, ductwork |
| Permits and HOA | Cosmetic work, no review | Permits, inspections and HOA approval |

Timeline factors
- Flooring acclimation, installation and, where applicable, finish cure time
- Whether the household stays in place, which can double the calendar for the same labour
- Millwork and stair part lead times, especially for custom profiles
- Paint sequencing, which generally has to follow trim and precede flooring finish
- Electrical rough-in and inspection where lighting changes are extensive
- Any structural work discovered once a wall is opened
Design considerations
- One trim profile and one door style for the whole floor, scaled to ceiling height
- Floor direction and continuity: running boards one way through the main spaces reads deliberate, changing at every doorway does not
- Stair detail, which is seen from more angles than any other millwork in the house
- Lighting in layers: ambient, task and accent, each on its own control
- Where to stop, because a material change at a logical boundary looks better than one carried a room too far
- Paint sheen and colour against the daylight each room actually gets
Permits and local review
Most interior finish work is not permitted, but electrical changes and any structural alteration are. Duluth sits in Gwinnett County and runs its own Community Development and Engineering department; whether your address is reviewed by the city or the county depends on city limits rather than your mailing address.
| If your home is in… | Permits usually come from | Good to know |
|---|---|---|
| Inside Duluth city limits | City of Duluth Community Development & Engineering | The city runs its own permits, applications and inspections |
| Unincorporated Gwinnett County | Gwinnett County | Many addresses with a Duluth mailing address sit outside city limits |
| Johns Creek, Suwanee, Berkeley Lake, Norcross or Peachtree Corners | That city’s own permit office | Each city sets its own submittal steps |
Always confirm the permitting office for your exact address; city limits do not follow ZIP codes.
How the work runs
| Step | What happens | What you receive | Decisions you make |
|---|---|---|---|
| 1. Discovery and consultation | Site visit, goals, budget range, photos and measurements | Notes on scope options and next steps | Which rooms and priorities to include |
| 2. Design and scope development | Layout, selections, structural and permit review | Written, line-item estimate and schedule | Finishes, allowances and phasing |
| 3. Construction | Permits, demolition, rough-ins, inspections, finishes | Regular progress updates; change orders in writing | Approve any change before work proceeds |
| 4. Punch list and walkthrough | Final details, cleaning and walkthrough | Signed punch list and care documents | Sign-off when items are complete |

Interior work usually accompanies kitchen remodeling and bathroom remodeling so flooring and trim carry through, and it is a core part of every whole-home remodeling plan. Lower-level finishes are covered under basement remodeling.
Frequently asked questions
Can my existing hardwood be refinished instead of replaced?
Often yes, if there is enough wear layer left above the tongue and the boards are not cupped or water damaged. We check thickness and condition before recommending it, because refinishing a floor that cannot take it wastes the money twice.
Is that wall load bearing?
It has to be established, not guessed. We look at what is above it, how the framing runs, and what the floor or roof is carrying. If it is structural, it can usually still come out with a properly sized and engineered beam.
Can you match my existing trim?
Usually. Standard profiles are widely available and custom profiles can be milled. Where an exact match is not practical, the better answer is often to change the profile throughout the floor rather than to accept a near miss at every doorway.
How disruptive is interior work?
Flooring and painting are whole-floor activities, so they are more disruptive than a single room remodel even though they are less complex. We contain and phase the work, and we are direct about which days are not liveable.
