Finish work posts at **$210 per hour**, lighting circuits at **$260**. ## What does interior work on an RV actually involve? Interior remodeling and repair covers floors, cabinets, wall and ceiling panels, upholstery, countertops and lighting inside a coach. Owners from Rancho Santa Margarita bring units to our Yorba Linda finish shop, where the first question is always whether water reached the structure behind the finish you can see. - A spongy floor is a subfloor problem, not a flooring problem - A stained ceiling panel means the leak above it is still there - Cabinets in a coach are built lighter than house cabinets on purpose - Lighting work bills at the electrical rate, not the finish rate ### Key facts | Item | Value | | --- | --- | | Price range | $500 to $50,000+ (4 to 250 labor hours at $210 per hour) | | Labor rate | $210 per hour (Body and paint department covers finish carpentry) | | Lighting rate | $260 per hour (Circuit work is mechanical and electrical) | | Typical stall time | 4 to 60 shop days (A full remodel is scheduled as a project) | | Dust control | Enclosed finish shop (Extraction at the tool so sanding dust stays out of the coach) | | Written estimate | $150 (Credited in full against an authorized repair) | Interiors get judged by their finish and fail by their structure. The stained ceiling panel, the cabinet door that no longer closes, the floor that gives near the entry step: those are symptoms, and about half the time the real job is behind the thing you can see. So this department starts with a moisture meter and a flashlight before it starts with a catalogue. Seven paths run out of this page. Six of them are targeted repairs to one system inside the coach. The seventh is a full rebuild, and if you are considering that, read the targeted pages first, because a great many owners who arrive asking for a remodel actually want three specific things fixed. ## Water first, finish second, always in that order The single most expensive habit in RV interiors is treating a symptom as the job. New vinyl plank over a wet subfloor lasts a season. A replacement ceiling panel under a leaking vent flange stains again in the first rain. A cabinet rebuilt where the wall behind it is soft comes loose again because there is nothing solid to fasten into. So every interior job here begins with a meter and a lamp. Readings go along the floor perimeter, under each window, at every roof penetration and inside the base of each cabinet run against an exterior wall. Where readings come back high, the source gets found and quoted as its own line item before any interior scope is written. That occasionally means telling an owner who came in for a countertop that they have a roof problem, which is not a fun conversation and is the correct one. > **warning:** If a shop quotes you new flooring for a spongy area without meter readings and without lifting a corner, they are quoting a cover, not a repair. ## Floors that give underfoot The classic locations are the entry step, the slide opening and the corner nearest the shower. All three are places where water gets in low and sits in a subfloor that is usually lauan or plywood laid over frame members. The covering is almost never the problem. The job is lifting it, cutting out saturated decking back to sound material, replacing framing where the moisture reached it, and only then laying a finish that will still be flat in five years. Cabinets and sometimes a slide room have to move to get at it. ## Cabinets that were built light for a reason Coach cabinetry is thin ply with stapled joinery and a face frame, built to a weight target rather than to a furniture standard. It fails predictably: fasteners pull out of the panel, face frames separate at the corners after enough road cycles, and hinges tear their mounting holes. The repair is about backing and joinery rather than replacement, and refacing is often the better value because the boxes are usually fine even when the doors look tired. Replacing coach cabinets with house grade units adds weight you may not have. ## Stained ceilings and soft wall panels Interior wall and ceiling panels in a coach are thin decorative sheet stretched over framing or bonded to insulation, which means they show water long before the structure does and they sag as soon as the adhesive lets go. A brown ring under a vent is the panel reporting a leak that started somewhere else, and by the time it sags the framing above it has usually been damp for a while. Matching an existing panel is its own challenge, since patterns are discontinued constantly and a full wall is sometimes the only way to avoid an obvious repair line. ## Seating, dinettes and everything covered in fabric Upholstery is the one interior category where the underlying structure is usually perfect and only the covering has aged. Thread degrades in ultraviolet light long before fabric does, so seams split while the material next to them looks fine. Foam takes a compression set and stops recovering. Reupholstering a dinette or a pair of theatre seats is generally better value than replacing them, and it also lets you choose a material rated for the sun exposure a coach actually gets, which the original rarely was. ## Countertops, sink cutouts and cracked corners Counters in a coach crack at stress risers rather than from impact: the inside corner of a sink cutout, the unsupported span next to a range, the front edge where somebody leaned. Solid surface material can be repaired invisibly if the crack is caught before it propagates through. Laminate over particle board usually cannot, because moisture has already swollen the substrate along the cut edge. Replacement is also a chance to correct the original support, which on many units was inadequate for the span. ## Lighting, which is an electrical job wearing an interior hat Interior lighting sits on this page because owners look for it here, but the work belongs to the electrical side and bills at that rate. A group of fixtures gone dim or dark is almost never bulbs. It is a connection at a splice, a switch that has burned internally, or a circuit sagging under load from an incandescent to LED conversion done without checking the dimmer. Upgrades are worth doing well: a proper LED conversion frees real amp hours on a house bank, and a badly done one flickers forever. ## Taking a coach back to shell A full remodel is a different animal from any of the above. Everything comes out, the shell gets inspected and repaired, and the interior goes back to drawings you have approved. It is scheduled as a project across months with staged deposits and progress photographs, and it makes sense for two kinds of owner: someone with a structurally sound coach whose layout no longer works, and someone with a unit nobody makes any more. It rarely makes sense as a way to fix three specific problems, which is what most people who ask for it actually have. ## Cost, weight and the payload nobody checks Interior finish work bills at $210 per hour from the body and paint department with body supplies at $5 per body hour, and any lighting circuit work inside the job bills at $260 per hour. Parts carry standard markup, sales tax applies to parts and materials, and labor is not taxed. Written estimates are $150 and credit in full against an authorized repair. The variable owners never raise is weight. Quartz counters, hardwood flooring, house grade cabinets and a residential refrigerator can add several hundred pounds to a coach that had a few hundred pounds of payload to begin with. We will build what you want, and we will tell you what it weighs first, because a beautifully remodeled coach that is over its axle rating is a problem you cannot see until a tire fails. > **price:** Full remodels take a 50 percent deposit at authorization with a further 25 percent when materials are ordered, and progress billing at agreed stages on longer projects. ## Interior claims and the argument about how long the water was there Almost every interior insurance dispute reduces to timing. A carrier pays for damage from a sudden event and declines damage from a leak that has been progressing for years, and a wet subfloor looks the same either way once you have opened it. What separates them is context: the condition of the sealant above the failure, whether staining shows layered tide lines, and whether the moisture pattern radiates from a single recent penetration. That evidence has to be gathered at intake, not reconstructed later. Meter readings with dates, photographs of the roof or window above the damage, and a note on when the owner first noticed it. Filed with the original scope, that record has settled far more of these claims than any argument made afterward. > **insurance:** Long term leak damage is excluded on every policy we bill. Where a sudden event has worsened pre existing rot, the two are separated in the scope so the covered portion can still be approved. ## Cost $500 to $50,000+, based on 4 to 250 labor hours at $210 per hour. Written repair estimate is $150, credited in full against an authorized repair. All work is performed in shop. ## Questions and answers ### Can I live in the coach while interior work is happening? Not during structural interior work. Floors come up, cabinets come out and the unit is not habitable, and it also sits inside a working building with limited access. Short cosmetic jobs are different and we will tell you at estimate which category yours is. ### How much weight can I actually add during a remodel? Look at the yellow cargo carrying capacity sticker inside your unit and subtract what you already carry. Many coaches have under a thousand pounds left. Quartz, hardwood and a residential refrigerator can consume most of that, which is why we weigh material choices before ordering. ### What if the wall panel pattern in my coach is discontinued? We either take the material from a hidden location such as inside a wardrobe and patch the visible area, or refinish the whole wall in a current pattern so the change happens at a corner. A patch in the middle of a wall in a near match is the option that always looks wrong. ### Can you replace just the soft section of subfloor? Yes, when the moisture map shows a defined wet zone with dry material around it. We cut back to sound decking, sister the framing where needed and splice new material over a support. What we do not do is leave damp decking under a patch, which is how the same floor comes back in two years. ### Does the slide room have to be moved to replace flooring? Frequently yes, because the flooring runs under the slide opening and the room has to travel to expose it. That adds mechanism work to a flooring job and it is quoted as its own line. Owners are often surprised by it, which is why we raise it at estimate rather than at invoice. ### There is a musty smell but no visible stain. Where do I start? With a meter, not with an air freshener. Musty odour with no stain usually means moisture inside a wall cavity or under a cabinet base where the finish is still intact. Readings along the floor perimeter and inside cabinet bases against exterior walls find most of them in under an hour. ### Does a full interior remodel help resale value? It helps sale speed more than price. Buyers pay for structure, mileage and systems, and they discount tired interiors heavily. A remodel that also corrected water damage documents well and sells. A cosmetic remodel over unaddressed rot does not, and an inspection will find it. ### Can original interior materials be preserved on a vintage unit? Where they are sound, yes, and we prefer it. Original birch panelling, cabinet hardware and trim can usually be removed carefully, refinished and reinstalled. What forces replacement is water damage and delaminated ply, and even then we salvage visible pieces and put new material where it is hidden. --- Source: [OCRV Center](https://ocrv.me/services/interior-remodeling-and-repair/).
