Flooring Repair and Replacement: Cost, Hours and Process in Hacienda Heights

On a coach the floor is not a surface sitting on joists. It is a laminated deck: a lower skin, a foam or block core, framing, and an upper layer of plywood or oriented strand board that the finish flooring bonds to. That assembly carries structural load and ties the sidewalls together at the bottom.

When water reaches it, the bond between layers releases and the deck loses stiffness. That is what a soft floor is. It is not a worn covering, it is a delaminated structural panel, and covering it with new flooring accomplishes nothing except hiding the progression.

So we read moisture across the floor on a grid before quoting a finish. If the deck is dry, this is a straightforward covering replacement. If it is wet, the wet area gets opened, the core and framing are repaired, and new decking is scarfed in flush before any covering goes down. That second job is priced separately so you can see exactly what you are paying for.

Luxury vinyl plank is the default for good reason. It is dimensionally stable across the temperature swing a parked coach sees in the San Gabriel Valley, it is genuinely waterproof at the wear layer, it is 1.4 to 2 pounds per square foot so it does not eat cargo capacity, and a damaged plank can be replaced without redoing the room.

Sheet vinyl, particularly a marine grade product, is the better answer in a wet bath or a galley where a seamless surface matters. Carpet still makes sense in a bedroom and in slide rooms where a hard surface would abrade the seal. Porcelain tile looks superb and is the one choice we push back on, because at 8 to 10 pounds per square foot over backer board it adds real weight and because grout lines crack on a structure that flexes unless the substrate is prepared with an uncoupling membrane.

Laminate with a fiberboard core is the material we will not install in a coach. One plumbing incident swells the core permanently and the whole floor is scrap.

• Luxury vinyl plank, stable, waterproof at the wear layer, 1.4 to 2 pounds per square foot
• Marine grade sheet vinyl, seamless, correct for wet baths and galleys
• Carpet in bedrooms and slide rooms where seal abrasion matters
• Porcelain tile only with an uncoupling membrane and a weight conversation first
• Fiberboard core laminate, not installed here at any price

More than owners expect, and this is the biggest driver of the hour count. To reach the floor under a slide room the slide has to be run out and supported. To reach the floor under a dinette or a sofa the furniture comes out. To finish the flooring properly at a cabinet the toe kick comes off, and on some coaches the cabinet itself has to be unfastened and lifted.

The alternative is what a cheap installer does: cut the covering around every obstruction and finish with a molding strip. That produces a floor with a hundred feet of caulked edge, every foot of which is a place water sits, and it makes any future cabinet or appliance change into a flooring job.

We quote the removal honestly. On a 34 foot coach with two slides, a dinette, a sofa and a full galley, expect the removal and reinstallation of furniture to be a meaningful share of the total hours, and expect the finished result to have flooring that runs continuously under the cabinet toe kicks.
