Whole-House Updates That Fix the Layout, Not Just the Finishes

About 23% of the homes in Warren County went up before 1980, and the 2025 Cost vs Value report shows why owners update rather than move: a midrange bath remodel recoups 76.8% in our region. Campbells Carpentry LLC takes on home remodeling across Warrenton, MO, Wentzville, and the Greater St. Louis area, from load-bearing wall removal and stair rebuilds to siding, decks, and porches, and the older-home updates that bring a 1970s ranch up to today's code.


We take on a house from roof to basement as a small, owner-operated company, so one carpenter plans the sequence, orders the lumber, and stands in the house daily. Over 5+ years we have kept to honest recommendations, telling you which walls can go and which should stay, and to doing what we say we will do. Estimates are free, so describe the trouble spots through our contact page and we will walk it with you.

Complete Home Remodeling We Provide

Whole-Home Renovations

Every room gets touched in a set order: structure, then rough plumbing, electrical, and HVAC through the trades we coordinate, then the open-wall inspection, insulation, drywall, and finish carpentry. Construction typically runs 4 to 8 months after 2 to 6 months of design.

Structural Updates and Wall Removal

Walls running perpendicular to joists or stacked over a beam below usually carry load. We replace them with an engineered LVL or steel beam on posts reaching the foundation, working from stamped drawings and shoring the floor until the beam is set.

Exterior Updates and Siding Coordination

New siding, a rebuilt front porch, a 16x16 deck with French doors, and replacement windows can land in one season. We frame porch roofs, set deck piers 30 in. deep, and schedule the siding crew so flashing and housewrap go on in order.

Aging Home Updates

Houses framed in the 1960s and 1970s often hide undersized headers, missing fireblocking, and stairs steeper than the 7 3/4 in. riser limit. We rebuild those pieces to the residential code, have the electrician add GFCI protection, and level floors that have settled.

Multi-Room Remodels

Opening a kitchen to the living room while reworking the hallway and a bath means one permit, one cleanup, and one inspection sequence instead of three. We phase the rooms so you keep a working kitchen or bathroom through the job.

Design and Planning

Before demolition, we measure the house, sketch the proposed layout, and check it against hallway widths of 36 in., stair headroom of 6 ft 8 in., and 7 ft ceilings for habitable rooms. You approve drawings and selections, then the schedule follows.

Why Choose Us for Home Remodeling

One Sequence, Roof to Basement

Renovating room by room over several years means paying for setup, permits, and cleanup repeatedly. We plan structure, exterior, and interior together, so the beam goes in before the flooring and the siding goes on before the replacement windows are trimmed inside.

Beams Sized Before Demolition

Nobody wants to discover a bearing wall after the sledgehammer swings. We identify load paths during planning, get the LVL or steel beam engineered, and have shoring in place before any framing comes out, so the ceiling never sags while the work happens.

The 50% Rule Worked Into Your Plan

Rebuilding under half the home's value in the same footprint carries no permit fee locally, while a changed roofline or footprint triggers a full permit. We explain where your project falls before you commit, so the permit path never surprises you mid-build.

Old Framing Brought to Today's Standards

A 1975 house was never built for GFCI outlets, R-38 attics, or interconnected smoke alarms. Along with the layout changes, you get a house whose hidden systems pass inspection and cost less to heat through a 20°F January night.

Fewer Weeks Behind Plastic Sheeting

Living through a renovation is easier when the disruption is compressed. We line up the trades back to back, order long-lead items such as windows and beams early, and keep the dust barrier moving so each finished area comes back to you quickly.

Inside and Out Under One Contractor

The deck, the porch, the siding, and the interior layout all belong to one project, so one carpenter carries the schedule and one number is yours to call. You avoid the finger-pointing that happens when three companies share a house.

Frequently Asked Questions

  • In what order should you do a full house renovation?

    Structure first, then the systems, then the finishes. That means demolition and beam work, foundation or framing repairs, rough plumbing and electrical, the open-wall inspection, insulation and drywall, flooring, cabinets, trim, and paint last. Exterior siding and decks slot in whenever weather allows.

  • Can I live in my house while it's being renovated?

    Usually, if one bathroom and a place to cook keep working through each phase. Jobs get split into zones behind a dust barrier, and the worst weeks, such as beam installation or floor sanding, can be planned around a short stay elsewhere.

  • How long does it take to remodel a 2,000 sq ft house?

    A top-to-bottom renovation of a 2,000 sq ft house runs about 4 to 8 months of construction after 2 to 6 months of design. Campbells Carpentry LLC builds a phased schedule for every Warrenton, MO, project so you know when each room returns.

  • How long does it take to renovate a small house?

    Smaller houses of 1,000 to 1,400 sq ft often finish in 3 to 5 months of construction, since fewer rooms means fewer trade handoffs. Structural changes, a raised roofline, or foundation repairs push toward the longer end, while cosmetic updates finish sooner.

  • How do I prepare for a home renovation?

    Clear the first-phase rooms completely, move valuables and electronics out of dust range, and set up a temporary kitchen with a microwave and a utility sink. Decide selections such as flooring, tile, and fixtures before demolition so nothing waits on a delivery.

  • What are common renovation mistakes?

    Removing a wall before learning what it carries comes first, then changing the plan after framing, buying finishes before the layout is final, and skipping the permit on work that changes the footprint. Ignoring drainage at a 1970s foundation costs the most later.

  • Is it better to buy a new house or remodel?

    Remodeling wins when the lot, the school district, and the mortgage rate are worth keeping and the house's bones are sound. Buying makes more sense when the foundation, roof, and systems all need replacement at once, because those items add little resale value.

  • Is renovating a house worth it?

    The 2025 Cost vs Value report says yes for most projects, with a minor kitchen update recouping 94.5% regionally and a basement finish 74.3%. Campbells Carpentry LLC in Warrenton, MO, has 5+ years of weighing those figures against how long you plan to stay.
