Why Choose MG Builders
Interior finishing requires a level of precision that general laborers can't deliver. Bad miter cuts, gapped joints, and uneven paint lines are obvious and permanent. MG Builders employs skilled finish carpenters who take pride in the details. After 29 years of finishing homes across Central New Jersey, the last 5% of a project is what homeowners notice most.
What Interior Finishing Includes
Interior finishing encompasses everything that happens after framing, rough electrical, and rough plumbing are complete. It's the work that transforms a structural shell into a livable, polished space. Interior finishing covers the full scope of work that transforms a shell into a polished space — whether as part of a larger renovation or as a standalone upgrade project.
Drywall installation and finishing is where most interior projects start. Hanging drywall is straightforward; finishing it to a paint-ready surface is where skill matters. Professional finishing involves taping seams, applying multiple coats of joint compound, and sanding to a Level 5 finish for walls in visible areas. Ceilings and high-traffic living areas get extra attention because light raking across an improperly finished surface makes every flaw obvious.
Trim work defines the character of a room. Baseboards anchor the wall to the floor; crown molding creates a visual transition between wall and ceiling; door and window casings frame openings with intention. Builder-grade homes often ship with the thinnest, flattest trim profiles available — a single upgrade to a more substantial profile can dramatically change a room's perceived quality. A wide range of trim profiles in MDF and solid wood are available, and custom profiles can be milled to match existing millwork in older homes.
Wainscoting and chair rail add depth and visual interest to dining rooms, hallways, and master bedrooms. Raised panel wainscoting is the traditional choice; shiplap and board-and-batten have become popular in more contemporary interiors. Both require precise layout, level installation, and clean paint lines to look intentional rather than amateurish.
Built-in shelving, entertainment centers, and window seats elevate a home's functionality and perceived value. Custom built-ins are fabricated and finished on-site to fit your specific wall dimensions, ceiling height, and design intent.
The difference between builder-grade and custom finishing isn't just materials — it's precision, paint prep, and the willingness to take the time to do it right. Skilled finish carpenters who have been doing this work for decades make the difference, and it shows.
Upgrading Interior Finishes in Older NJ Homes
Central New Jersey has an enormous stock of homes built between the 1950s and 1980s — Cape Cods, split-levels, ranches, and colonials that were well-built structurally but finished with the minimal materials and techniques of their era. Upgrading the interior finishes in these homes is one of the highest-return projects a homeowner can undertake, both for daily livability and for resale value.
Popcorn ceilings — the textured acoustic spray applied to millions of ceilings from the 1960s through the 1980s — are the most common complaint from owners of homes in this era. Removing them requires scraping (after testing for asbestos content, which is present in some pre-1978 applications), skim-coating the underlying surface, and applying a smooth finish or a more contemporary light texture. The result is a dramatic visual improvement throughout the home. NJ homes built before 1978 should be tested before any ceiling disturbing work begins; all applicable regulations must be followed.
Outdated trim is another hallmark of 1960s-1980s construction. Many homes from this era have colonial-style casing that is 2.25 inches wide and completely flat — minimal by today's standards. Replacing it with a more substantial profile (3.5 inches or wider, with more relief) modernizes a room immediately. Replacing trim throughout an entire floor in a single project creates a cohesive, upgraded look.
Hollow-core interior doors are standard in builder-grade construction from this era. They sound hollow when knocked on, provide essentially no sound attenuation between rooms, and look insubstantial. Upgrading to solid-core doors improves both acoustics and perceived quality significantly. Door replacement includes boring and installing new hardware and adjusting frames where needed.
Wall and ceiling imperfections that have been buried under multiple layers of paint since the 1960s often need to be addressed before any finish work can look good. Skim-coating walls where necessary, repairing plaster cracks, and ensuring every surface is properly prepared before paint goes on is essential. Proper prep is the difference between a finish that looks fresh for 10 years and one that reveals every flaw within a season.
Frequently Asked Questions
Can you match my existing trim and molding?
In most cases, yes. Matching profiles can be sourced or custom molding can be milled to match existing trim. Samples are brought to the home to ensure a perfect match before installation.
How much does crown molding cost to install?
Crown molding installation costs depend on profile size, material (MDF, pine, or solid hardwood), and room complexity. Rooms with angles and vaulted ceilings require more labor. MG Builders provides free estimates for all interior finishing work. Call (732) 636-3000.
Do you do drywall repair?
Yes. MG Builders handles drywall installation for new construction and remodels, as well as repairs for holes, cracks, water damage, and uneven surfaces. All drywall work includes taping, mudding, sanding, and a paint-ready finish.
Can you paint my entire house interior?
Yes. Full interior painting covers walls, ceilings, trim, doors, and cabinets. All surfaces are prepped, quality paints are used, and furniture and flooring are protected throughout the process.
How long does interior painting take per room?
A standard bedroom (12x12) takes 1-2 days for full prep, 2 coats on walls, and trim painting. Larger living rooms or open-concept spaces take 2-4 days. Whole-house interior painting (3-bed/2-bath home) typically takes 5-10 days. Cabinet painting requires additional time for proper degreasing, sanding, and multiple finish coats — usually 4-7 days for a kitchen.
What is the best time of year for interior painting?
Interior painting can be done year-round, but moderate temperature months (April-June, September-November) are ideal because windows can be opened for ventilation and paint cures faster. Winter painting works fine with proper ventilation. Summer humidity can extend drying times slightly. Quality of work doesn't change with season — just timeline factors.
Can MG Builders install new doors and casings?
Yes. Interior door installation includes existing door removal, new pre-hung door installation, jamb adjustments, casing trim, hinge alignment, and hardware (knobs, latches). Custom casings and decorative trim packages add visual upgrade to standard openings. Doors typically take half a day each including casing — 6 doors can usually be completed in 2-3 days.
What is included in an interior finishing estimate?
Interior finishing estimates include all materials (trim, casings, paint, primer, fasteners), surface preparation, installation labor, and final cleanup. For trim work, exact wood species and profile dimensions are specified. For painting, exact paint brand, finish (eggshell, satin, semi-gloss), and number of coats are documented. A 12-month workmanship warranty is included.
