Preparation Before Painting

Eighty percent of paint durability depends on setup. We protect every surface and eliminate substrate flaws before any topcoat opens.

Floor & Furniture Masking

Drywall Patching & Repair

Dustless Vacuum Sanding

Patched areas undergo HEPA-filtered vacuum sanding, creating smooth surfaces without spreading fine plaster dust into living spaces.

Heavy-duty floor guard paper is taped edge-to-edge over hardwood and stone. All furniture is centralized and sealed under heavy plastic sheeting.

Dents, nail pops, and joint cracks are patched with lightweight compound, reinforced with fiberglass mesh, and feathered flush with existing plaster.

Formulation & Sheen

Interior Paint Systems & Sheen Selection

Selecting the correct finish balance ensures surfaces withstand daily life while maintaining depth. We apply premium zero-VOC washable matte for living quarters, velvety eggshell for corridors, and ultra-smooth acrylic enamel across moisture-prone bath and kitchen zones.

Every coat is applied with precise film thickness gauges to guarantee uniform color saturation and eliminate lap marks. Ceilings receive dead-flat white formulations designed to absorb overhead glare and mask subtle structural panel transitions.

Precision Alignment

Architectural Trim & Millwork Refinishing

Baseboards, door casings, wainscoting, and crown molding demand laser-straight color lines and porcelain-smooth topcoats. We hand-sand wood trim between coats to achieve an immaculate furniture-grade finish.

Whether restoring original historic moldings or finishing modern custom cabinetry, our masked line edges create sharp separation between wall paints and woodwork.
