Flooring Built for a Dry Climate and a Moving Subfloor

Colorado is hard on wood floors in a way that surprises people who move here. Wood takes on and gives up moisture with the air around it, and the air here is dry — especially through winter, when the heating runs and indoor humidity drops further. Boards shrink, and thin gaps open along the seams. Come summer they take moisture back on and close up again. That seasonal movement is normal and it is not a defect. What separates a floor that handles it from one that fails is whether the material was allowed to acclimate to your house before installation, whether the right expansion gap was left at the walls, and whether the species and construction suited the conditions in the first place. Rushing a floor in the week it was delivered is one of the most common reasons a hardwood installation goes wrong here.

The subfloor decides the outcome more than the flooring does. It needs to be flat within the tolerance the manufacturer specifies, structurally sound, dry, and clean. If it is not flat, you get hollow spots underfoot, clicking, and planks that separate at the joints over time. Most manufacturer warranties are written to exclude failures caused by improper subfloor preparation, which means a floor installed over a subfloor nobody assessed is a floor with no real warranty behind it. This is also the single most common source of surprise cost on a flooring job. We assess it before quoting so that the number we give you includes whatever the subfloor actually needs, rather than appearing as a change order once the old floor comes up.

Concrete gives off moisture, and a basement slab sits against ground that holds water. That moisture has to go somewhere, and if flooring is installed over a slab without testing it first, it goes into the flooring — which is how you end up with cupping, adhesive failure and, in the worst cases, mould underneath a floor that looked perfect when it was finished. So we test slabs before installing over them, and we specify the assembly around what the test says: the right moisture barrier or underlayment, and a material that can live with the conditions. Solid hardwood is generally not the right choice below grade. Engineered wood and quality luxury vinyl plank are built to tolerate it, and in a basement they will outlast solid hardwood by a wide margin.

If you already have solid hardwood, replacing it is often the wrong move. Solid wood can be sanded and refinished more than once, depending on how much wear layer is left, and refinishing an existing floor is typically far cheaper than tearing it out and buying a new one. Engineered wood can sometimes be refinished too, depending on the thickness of its top layer. We will tell you which situation you are in. If your floors can be brought back rather than replaced, that is what we will recommend, even though it is the smaller job.

We do not have a product we push. Different rooms want different things: a basement wants something that can handle moisture, a kitchen wants something that survives a dropped pan and a spilled pot, a bedroom can take a softer material, and a house with large dogs wants a wear layer that can cope with them. We will tell you what each option costs, what it does well, where it fails, and what we would put in our own house — including when the cheaper option is genuinely the better one.
