Getting ready to install engineered wood and tile in a new build? Use this simple checklist for baseboards, slab prep, and climate control before your installer arrives.

We recently got a call from a customer — let’s call him Mark — who had just built a new home out in the country. The walls were up, the baseboards were already installed, and the concrete slab looked clean. He had 1,400 square feet of engineered wood and tile sitting in a barn on the property and was ready for us to “just come install it.”
As we talked, a few red flags started popping up: baseboards were already nailed on, the slab hadn’t been checked for flatness or moisture, and the air conditioning wasn’t running yet. All of those things matter a lot when you’re installing glued-down engineered wood and tile in a new build.
We walked Mark through a simple pre-installation checklist so that when we showed up, we could focus on quality installation instead of fixing avoidable problems. That conversation is exactly what inspired this guide.
In Mark’s case, the builder had already installed the baseboards before any flooring went in — which is common, but not ideal. If you’re not careful, this one detail can add time, cost, and headaches.
Here are the two main options we talked through with Mark:
For glued-down engineered wood, we need a proper expansion gap along the perimeter. If the baseboards stay, that gap will be visible unless we cover it with quarter round.
When Mark told us the house was “just concrete,” he figured that meant we could simply glue the engineered wood down and start setting tile. In reality, new slabs are rarely flat enough or dry enough to skip prep.
Even in brand-new construction, concrete foundations usually have humps, dips, and waves. For glued-down engineered wood, most manufacturers require the slab to be flat within about 3/16" over 10 feet (or similar tolerances). Tile is even less forgiving — a high or low spot can cause lippage and cracks.
On Mark’s project, we planned to:
If you walk your slab and feel “speed bumps” under your feet or you see shadows where light hits the floor, you almost certainly need prep.
New slabs may look dry, but they often still have moisture moving up through the concrete. That’s a big concern for engineered wood and can also affect tile adhesives.
Common moisture checks we recommend:
If readings are too high, we may need a moisture barrier or specialized adhesive before installing engineered wood.
One of Mark’s big questions was about air conditioning: the system wasn’t hooked up yet, and he wondered if that would be a problem. For engineered wood, the answer is yes — it’s a big problem.
Engineered wood is more stable than solid hardwood, but it still expands and contracts with changes in temperature and humidity. If we install it in a hot, humid “construction climate” and then you turn on the AC a month later, you can end up with:
Most manufacturers specify a “normal living condition” range — typically around 60–80°F and 30–50% relative humidity — that should be maintained before, during, and after installation.
We told Mark that even though his wood was stored on the property, it still needed to be brought into the house and acclimated in the actual living conditions. That usually means:
In his case, a temporary window unit or portable AC to stabilize conditions before install was a smart workaround until the main system was ready.
New construction is a juggling act. What made Mark’s project smoother was that we talked early, before we ever loaded the truck. Here are a few patterns we see over and over:
When we finished walking Mark through this checklist — baseboards and trim, concrete prep, and climate control — he had a clear plan: remove the baseboards before we arrived, get the AC running (even if with a temporary unit), and give us access to a clean, empty slab. That prep work meant we could focus on installing his engineered wood and tile the right way the first time.
If you’ve got flooring waiting in a new construction home, taking these steps before we show up can save you time, money, and a lot of stress — and it gives your new floors the best chance to look great and last for years.
