Portland Interior Remodeling Services

Every Portland home tells a story through its interior spaces. Whether you own a 1920s Craftsman in Laurelhurst with original fir trim darkened by a century of use, a mid-century ranch in Milwaukie ready for an open-concept transformation, or a newer build in Hillsboro that simply needs a functional upgrade, the interior is where daily life happens. It deserves to work as well as it looks.

Boss PDX is a licensed general contractor (Oregon CCB #232383, Washington License BOSSPPL793RN) specializing in interior remodeling across the Portland metro area. We handle projects from single-room refreshes to whole-home renovations, managing every trade, every permit, and every detail so you get a finished space that fits your household and your budget.

Kitchen Remodeling

The kitchen is the most-used room in any home and typically the highest-value remodel you can undertake. In Portland's older housing stock, kitchens were often designed as small, closed-off rooms separated from dining and living areas by load-bearing walls. Modern households want something different: open sightlines, functional work triangles, and storage that actually accommodates how people cook today.

Our kitchen remodeling services cover full gut renovations, cabinet refacing, countertop replacement, lighting upgrades, appliance installation, and layout reconfiguration. We work with every budget level, from refreshing an existing kitchen with new countertops and hardware to stripping a room down to the studs and starting fresh with custom cabinetry, under-cabinet lighting, and new plumbing and electrical rough-in.

For Craftsman and bungalow kitchens, we pay particular attention to integrating modern conveniences while preserving period-appropriate details. Built-in hutches, glass-front upper cabinets, and bin-pull hardware can honor the home's original character while delivering the function of a contemporary kitchen.

Bathroom Remodeling

Portland's older homes frequently have bathrooms that are cramped, poorly ventilated, and overdue for attention. Original hex-tile floors, cast-iron tubs, and pedestal sinks have charm, but aging supply lines, inadequate ventilation, and outdated waterproofing behind tile walls create real problems. Water damage behind bathroom walls is one of the most common issues we encounter in pre-war Portland homes.

Our bathroom remodeling services range from cosmetic updates like new tile, vanities, and fixtures to complete tear-outs addressing subfloor rot, re-plumbing, exhaust fan installation, and accessibility upgrades such as curbless showers and grab bars. We install tile showers with modern waterproofing membrane systems, ensuring the work behind the walls is as solid as the finished surface.

Wall Removal and Open-Concept Conversions

Opening up a floor plan is one of the most transformative interior changes you can make, and it is one of the most common requests we receive from Portland homeowners. Removing the wall between a kitchen and dining room or connecting a living room to an adjacent den can dramatically change how a home feels and functions.

Not every wall can simply be torn out. Many interior walls in Portland's older homes are load-bearing, meaning they support the floor or roof structure above. Removing a load-bearing wall requires engineering: a licensed structural engineer designs a beam and post system to carry the load, and the City of Portland's Bureau of Development Services (BDS) requires a structural permit with stamped engineering drawings before work begins.

We manage this entire process. Our team coordinates with structural engineers, pulls the necessary BDS permits, installs temporary shoring to support the structure during construction, sets the engineered beam, and finishes the ceiling and walls so the former wall location is invisible. The result is a continuous, open space with proper structural support hidden above the ceiling line.

Dealing with Plaster Walls

Many Portland homes built before 1950 have plaster-and-lath walls rather than drywall. Plaster is durable and provides excellent sound dampening, but it presents unique challenges during remodeling. Cutting into plaster for electrical or plumbing work requires different techniques than drywall. Plaster cracks differently, fastens differently, and patches differently.

When we work in plaster homes, we evaluate each wall individually. In some cases, preserving the original plaster makes sense — it is a superior wall surface in many respects. In other cases, particularly where extensive electrical or plumbing work is needed behind the wall, replacing a section with drywall and matching the texture is more practical and cost-effective. We discuss these trade-offs with you before any demolition begins.

Flooring

Flooring sets the tone for every room. Our flooring installation services cover hardwood, engineered wood, luxury vinyl plank (LVP), tile, and carpet. In older Portland homes, we frequently refinish original Douglas fir or oak hardwood floors that have been hidden under carpet for decades. When the original flooring is too damaged to save, we install new material that matches the home's character.

For basements and below-grade spaces, moisture management is critical. Portland's wet climate means below-grade concrete slabs often have moisture vapor transmission issues. We test moisture levels before recommending any flooring product and install appropriate vapor barriers or subfloor systems when needed.

Painting, Drywall, and Interior Finishes

A fresh coat of paint is the fastest way to change the feel of a room, but proper surface preparation is what separates a professional result from a weekend project. We repair cracks, skim-coat damaged drywall, prime stains, and caulk trim joints before any finish paint goes on. In older homes with textured plaster ceilings or walls, we match existing textures so repairs blend seamlessly.

Our drywall services include new installation for additions and remodels, patching and repair, and level-five finishing for smooth walls. We also handle popcorn ceiling removal, a common request in Portland homes built during the 1970s and 1980s. Before removing any textured ceiling material in homes built before 1980, we test for asbestos and follow all DEQ abatement protocols if it is present.

Trim, Millwork, and Custom Carpentry

Original trim and millwork are defining features of Portland's Craftsman bungalows, Foursquares, and Colonial Revival homes. Wide baseboards, picture rails, plate rails, built-in bookcases, window seats, and paneled wainscoting give these homes their character. When this woodwork has been removed, damaged, or painted over with decades of buildup, restoring it transforms the entire interior.

Our custom cabinetry and carpentry team replicates original trim profiles, builds new built-ins to match existing ones, and installs crown molding, chair rail, and wainscoting in both traditional and contemporary styles. We mill custom trim profiles when standard lumber-yard stock does not match the originals in your home.

Closet Systems and Storage Solutions

Older Portland homes are notorious for minimal closet space. Bedrooms may have a single small closet — or none at all, since closets were not standard in homes built before the 1920s. We design and install custom closet systems that maximize every inch of available space, including built-in dressers, adjustable shelving, double-hang rods, and pull-out accessories.

Beyond closets, we build pantry storage systems, mudroom cubbies, under-stair storage, and garage organization systems. Functional storage is one of the most practical upgrades you can make to an older home, and it consistently ranks among the improvements that homeowners value most in daily life.

Basement Finishing

Portland's housing market makes unfinished basements an attractive opportunity. Converting a basement into livable space — a family room, home office, guest suite, or rental unit — adds functional square footage at a lower cost per square foot than a room addition.

Basement finishing in the Portland area requires attention to moisture management, egress requirements, ceiling height limitations, and mechanical system routing. We install interior drainage systems and sump pumps when needed, frame and insulate walls with moisture-resistant materials, ensure adequate egress windows for bedrooms per Oregon building code, and route HVAC, plumbing, and electrical to serve the new space. BDS permits are required for basement conversions that add habitable space, and we handle the entire permitting process.

Whole-Home Renovations

Sometimes a home needs more than a single room updated. Whole-home renovations address multiple systems and spaces simultaneously: updating the kitchen and bathrooms, refinishing floors throughout, replacing trim, repainting every room, upgrading electrical panels, and improving insulation. Taking on the entire home at once is disruptive, but it is also more efficient and cost-effective than tackling one room at a time over several years.

We sequence whole-home projects carefully to minimize disruption and avoid rework. Rough trades like plumbing, electrical, and HVAC go in first. Then insulation, drywall, and painting. Then flooring. Then trim, cabinets, and fixtures. Finally, finish details and punch list. This sequence ensures each trade's work is protected and that the project moves forward without backtracking.

Energy Efficiency in Older Portland Homes

Interior remodeling is the ideal time to address energy efficiency. When walls are open for plumbing or electrical work, adding insulation is minimally invasive and dramatically improves comfort and heating costs. Portland's older homes were often built with no wall insulation at all, and single-pane windows remain common in homes that have not been updated.

We install dense-pack cellulose or spray foam insulation in open wall cavities, upgrade attic insulation to current code levels, seal air leaks around windows, doors, and penetrations, and coordinate window replacement when it is part of the scope. These improvements pay for themselves through reduced heating bills and make the home significantly more comfortable during Portland's damp, cool winters.

Interior Remodeling Costs in Portland

Interior remodeling costs vary widely depending on scope, materials, and the condition of the existing structure. Here are general ranges for common projects in the Portland market:

• Kitchen remodel: $25,000 to $85,000+ depending on size, layout changes, and material selections
• Bathroom remodel: $15,000 to $45,000+ depending on scope and fixtures
• Wall removal (load-bearing): $5,000 to $15,000 including engineering and permits
• Hardwood floor refinishing: $3 to $6 per square foot

These ranges reflect Portland-area labor rates and material costs. Every project is different, and we provide detailed, line-item estimates before any work begins. Request a free estimate to get pricing specific to your project.

Project Timelines

Realistic timelines help you plan around the disruption of a remodel. Typical durations for Portland interior projects:

• Bathroom remodel: 3 to 6 weeks
• Kitchen remodel: 6 to 12 weeks
• Wall removal: 1 to 3 weeks (plus 2-4 weeks for engineering and permits)
• Basement finishing: 8 to 14 weeks
• Whole-home renovation: 3 to 6 months

BDS permit review times add to these durations. Simple permits may be issued in days through BDS's expedited review process, while structural permits requiring plan review typically take 4 to 8 weeks. We submit permit applications as early as possible to minimize schedule impact.

Living in Your Home During a Renovation

One of the most common questions we hear is whether you can stay in your home during an interior remodel. The answer depends on the scope of work. For a single bathroom or bedroom renovation, most homeowners stay in the home comfortably. For a kitchen remodel, we set up a temporary kitchen area with your refrigerator, microwave, and a utility sink so you can manage meals without the full kitchen.

For whole-home renovations, living in the home is possible but requires tolerance for dust, noise, and limited access to certain rooms. We use dust barriers, floor protection, and negative air pressure systems to contain construction debris, but a major renovation is inherently disruptive. Some homeowners choose to stay with family or rent short-term housing during the most intensive phases. We help you evaluate this decision based on your specific project scope and household needs.

Frequently Asked Questions

Do I need a permit for interior remodeling in Portland?

It depends on the scope. Cosmetic work like painting, flooring, and cabinet replacement does not require a permit. However, any work that involves structural changes (wall removal, new openings), electrical modifications, plumbing alterations, or changes to the building envelope requires permits from the City of Portland Bureau of Development Services (BDS). Adding habitable space in a basement or attic also requires permits. We determine permit requirements during the estimating phase and handle all applications, inspections, and approvals on your behalf.

How much does it cost to remodel the interior of a house in Portland?

A single-room remodel typically ranges from $15,000 to $50,000 depending on the room and scope. Whole-home interior renovations generally range from $100,000 to $300,000 or more. The biggest cost drivers are the extent of structural work, plumbing and electrical changes, material selections (stock vs. custom cabinetry, laminate vs. quartz countertops, LVP vs. hardwood flooring), and the condition of the existing structure. Older homes with outdated wiring, galvanized plumbing, or structural issues cost more because those systems must be brought up to current code during the remodel. Contact us for a free estimate tailored to your home and goals.

Can you match the original trim and woodwork in my Craftsman home?

Yes. We replicate original trim profiles using custom milling when standard profiles are not available. Portland's Craftsman and bungalow homes feature distinctive woodwork — wide flat-stock casings, tapered columns, built-in buffets, plate rails, and box-beam ceilings — and we have extensive experience restoring and reproducing these details. We can also strip and refinish original woodwork that has been painted over, though this is labor-intensive and we help you weigh the cost against replacement with matching new material.

How long does a typical interior remodel take?

A bathroom remodel typically takes 3 to 6 weeks. Kitchen remodels run 6 to 12 weeks. Whole-home renovations take 3 to 6 months. These timelines include construction only — add 2 to 8 weeks for design, engineering, and permit review before construction starts. We provide a detailed project schedule before breaking ground and communicate updates weekly throughout the build. Delays are most commonly caused by permit review backlogs, material lead times on special-order items, and unforeseen conditions discovered during demolition.

What challenges come with remodeling older Portland homes?

The most common challenges include plaster-and-lath walls that require specialized repair techniques, original knob-and-tube wiring that must be replaced when walls are opened, galvanized steel supply pipes that are corroded and restrict water flow, lead paint on trim and walls in homes built before 1978, asbestos in floor tiles, pipe insulation, and textured ceilings in homes built before 1980, narrow hallways and non-standard framing dimensions, and foundations that have settled unevenly over decades. None of these are deal-breakers, but they require experience and proper handling. We assess these conditions during our initial walkthrough and build appropriate contingencies into our estimates.

Do you handle the design, or do I need to hire a designer separately?

We offer design-build services for most interior projects, meaning we handle both the design and construction under one contract. For kitchen and bathroom remodels, we work with you on layout, material selections, and fixture choices using our supplier showrooms and digital design tools. For complex projects or clients who want a high level of architectural detail, we collaborate with independent interior designers and architects. Either way, design decisions are finalized before construction begins so the project stays on schedule and on budget.
