RainFire Builders delivers precision craftmanship across every interior discipline, from rough framing through to the final trim, from underground plumbing to smart electrical systems.

OUR INTERIOR SERVICES

TEN TRADES, ONE TRUSTED TEAM with RAINFIRE.

Every service RainFire Builders offers is performed by our own trained craftsmen – not day-labor subcontractors. That means consistent quality, direct accountability, and seamless coordination from the first framing nail to the final coat of paint.

FRAMING

Interior framing is the skeletal system of every building. RainFire Builders provides expert wood and steel stud framing for walls, ceilings, soffits and structural openings – ensuring your home meets code, stands square, and supports every finish system that follows.

  • Load-bearing & non-load-bearing wall systems
  • Steel stud framing for commercial applications
  • Ceiling framing, dropped ceilings, & soffits
  • Door & window rough openings, headers & lintels
  • Stair framing & platform construction
  • Structural header & beam placement

For new construction, RainFire Builders handles complete interior wall framing, including layout, plating, stud installation, header work, fire blocking, and blocking for future fixtures – coordinated tightly with plumbing and electrical rough-in schedules.

The Structural Backbone

DRYWALL & PLASTER

From clean Level-5 finishes in luxury homes to high-impact plaster textures in commercial spaces, RainFire Builders delivers drywall and plaster work with zero shortcuts. Our crews hand, tape, mud, and finish to exacting standards – surfaces that paint and tile love.

  • Level 1-5 drywall finishing grades
  • Smooth, orange peel, and knockdown textures
  • Moisture-resistant and Type X fire-rated board
  • Veneer and three-coat plaster systems
  • Arched and curved wall framing & boarding
  • Repair patching for remodeling projects

Level 4 finish is the standard for most painted walls. Level 5 adds a skim coat over the entire surface, eliminating any surface variation – it’s specified where flat or enamel paints are used, and in high-end Utah custom homes where lighting reveals every imperfection of the wall.

Seamless Walls & Ceilings

FLOORING

Flooring sets the character of every interior space. RainFire Builders installs all major flooring systems – from solid hardwood and large-format tile to luxury vinyl plank and polished concrete – with proper subfloor prep and manufacturer-approved methods that protect your investment for decades.

  • Solid and engineered hardwood installation
  • Large-format porcelain & natural stone tile
  • Luxury vinyl plank (LVP) and LVT
  • Carpet installation – bedroom to whole-home
  • Heated radiant floor system rough-in
  • Subfloor leveling repair and moisture testing

Utah’s low humidity and temperature swings make engineered hardwood or LVP ideal – both resist contraction and expansion better than solid wood. RainFire Builders always performs moisture and flatness testing before installation to prevent callbacks.

Surfaces you’ll love underfoot

PAINTING

A flawless paint job requires far more than rolling on color – it demands expert surface prep, proper primer selection, clean cutting, and consistent application across every coat. RainFire Builders’ painting crews are trained in both production and finish work, delivering crisp, even results on every interior surface.

  • Full interior painting – new construction & remodel
  • Primer sealing and stain blocking applications
  • Spray, roller, and brush finish techniques
  • Cabinet and millwork refinishing
  • Accent walls, faux finishes, & decorative effects
  • Commercial interior painting – tenant improvements

New drywall requires a PVA primer, then typically two coats of finish paint for uniform sheen and coverage. RainFire Builders follows manufacturer specs and inspects under raking light between coats – an extra step most crews skip.

Color, craft & lasting coverage

TRIM & MILLWORK

Architectural trim and custom millwork elevate a room from ordinary to extraordinary. RainFire Builders’ finish carpenters bring precision to every profile – from simple colonial casing to elaborate coffered ceilings and built-in bookshelves – delivering the craftsmanship that sets a home or office apart in Utah’s luxury-driven market.

  • Baseboard and door/window casing installation
  • Crown molding – simple to built-up profiles
  • Wainscoting, paneling & board and batten
  • Coffered and tray ceiling construction
  • Built-in bookshelves, benches & custom built-ins
  • Fireplace mantels and surround carpentry

Trim refers to moldings installed on-site (baseboards, casing, crown). Millwork typically describes pre-manufactured or custom-shop woodwork – the mantels, built-ins, and panelling – that arrives ready to install. RainFire Builders handles both.

The details that define a space

INSULATION

PropeProper insulation is one of the highest-ROI investments in any Utah home. With temperature swings from sub-zero winters to 100-degree summers, RainFire Builders specifies and installs the right insulation system for your climate zone, construction type, and energy goals – reducing utility bills and improving year-round comfort.

  • Fiberglass batt – exterior walls, attics & floors
  • Blown cellulose and mineral wool
  • Open and closed-cell spray foam systems
  • Rigid foam continuous insulation
  • Sound attenuation for interior walls & ceilings
  • Utah climate zone R-value compliance (Zones 5-8)

Salt Lake City falls in Climate Zone 5. The energy code requires R-20 or R-13-5 in exterior walls, R-49 in attic/ceiling assemblies, and R-30 in floors over unconditioned spaces. RainFire Builders ensures every project meets or exceeds these requirements.

Comfort, efficiency & quiet

CABINETRY & COUNTERTOPS

The kitchen and bathrooms are the rooms that sell a home – and where quality cabinetry and countertops matter most. RainFire Builders works with leading cabinet lines and stone fabricators across Utah to deliver custom and semi-custom solutions that balance beauty, budget, and functionality for every project.

  • Custom, semi-custom, and stock cabinetry
  • Kitchen layout planning & cabinet specification
  • Quartz, granite, and quartzite countertops
  • Butcher block, concrete, and solid surface options
  • Bathroom vanity, linen tower & specialty cabinetry
  • Hardware selection and installation

Quartz surfaces lead the category for family kitchens – non-porous, scratch-resistant, and available in hundreds of styles. For those seeking natural stone, quartzite is harder and less porous than marble. RainFire Builders coordinates templating, fabrication, and installation as a single package.

Kitchens & baths, crafted right

INDOOR PLUMBING

Indoor plumbing done right means no leaks, no callbacks, and no surprises behind your finished walls. RainFire Builders’ licensed plumbers handle everything from below-slab drain rough-in and PEX supply systems to finish fixture setting and code inspections – ensuring every faucet, shower, toilet, and water feature performs flawlessly from day one.

  • Below-slab and under-floor drain rough-in
  • PEX and copper supply line installation
  • Kitchen, bath, laundry & utility rough-in
  • Water heater installation – tank & tankless
  • Finish fixture setting – faucets, toilets, showers, etc.
  • Pressure testing and city inspection coordination

Rough-in is the hidden work – running drain lines, supply pipes, and vent stacks through framing before drywall. Finish plumbing installs the visible fixtures – faucets, showerheads, toilets, and valves, among other water-related details – after surfaces are complete. RainFire Builders handles both phases with licensed crews.

Water when and where you need it

ELECTRICAL

Modern home electrical goes well beyond outlets and switches. RainFire Builders’ licensed electricians design and install complete interior electrical systems – from service panel sizing and circuit design through recessed lighting layouts, USB charging integration, EV charger wiring, and structured smart home systems.

  • Electrical rough-in – all circuits, boxes & conduit
  • Panel sizing, sub-panels & service upgrades
  • Recessed and specialized architectural lighting layouts
  • Low-voltage – data, audio, and home automations
  • EV charger installation (Level 2)
  • Kitchen & bath GFCI and AFCI compliance

Frequently, an upgrade is needed. Most Utah homes built before 2000 have 100-amp service – undersized for modern loads, especially with EVs or added square footage. RainFire Builders assesses existing capacity and coordinates any necessary upgrades with Rocky Mountain Power as part of your project.

Power, light & smart systems

HVAC

Utah’s climate demands a well-designed HVAC system – freezing winters, scorching summers, and wildfire smoke seasons in between. RainFire Builders designs and installs complete HVAC systems for new construction and remodels, from ductwork layout and equipment selection to commissioning and smart thermostat integration.

  • Forced air furnace & AC system installation
  • Ductwork design, fabrication & installation
  • Heat pump systems – air source & geothermal
  • Mini-split ductless systems for additions
  • ERV/HRV ventilation for modern tight homes
  • Smart thermostat and zoning systems integration

For most new Utah builds, a high-efficiency gas furnace paired with a 16+ SEER central air conditioner remains the most cost-effective. For homes pursuing net-zero or high-performance targets, RainFire Builders recommends variable-speed heat pumps and ERV ventilation – offering both heating and cooling efficiency with improved air quality.

Climate control, done right
