What's Behind the Drywall in a New Home

Two new houses on the same street can share a size, a floor plan, paint colors, light fixtures and flooring, and look identical at the final walkthrough. One of them can still be a much better house than the other. The difference is behind the drywall.

People ask me what they are paying for when they build a custom home. A lot of the answer is the part you cannot see once the walls are closed.

What You Can’t See After the Walls Close

Here is what gets covered up during a build, and what can be different from one house to the next.

Insulation

Insulation decides how comfortable the house is and what it costs to heat and cool, especially through a Texas summer. The type, the thickness and how carefully it is installed around corners, outlets and windows all matter. Gaps that nobody sees still show up on the electric bill. Our guide to spray foam vs blown-in insulation covers the main options.

Waterproofing

Water is the biggest long-term threat to a house. Flashing around windows and doors, the weather barrier under the siding or brick, and the waterproofing under showers all keep it out. When any of those are done poorly, the damage stays hidden in the wall until it is expensive.

Termite Control

In Texas, termite treatment is a standard part of building a new home. It goes in before the slab and around the foundation, and once the house is finished there is no way to see it.

Wiring

The electrical system behind the walls includes the size and number of circuits, the quality of the connections and where everything is routed. Two houses with the same outlets and switches can have very different wiring behind them.

Plumbing

Supply lines, drains and shutoffs all run inside the walls and under the slab. The materials and the care taken at every joint decide whether the system lasts or leaks.

The Structure Is the Backbone of Your Home

Lighting and fixtures and all the pretty stuff that you see can be changed. You can swap a light fixture in an afternoon or replace a countertop in a few days.

The structure of your home is the backbone of your home, and it is critical. The foundation, the framing and the roof structure are built once. If they are done well, everything you add later has something solid to sit on. If they are not, no finish selection will make up for it.

Think of It Like Two White Cars

You can have two white cars that look exactly the same in the parking lot. One has leather seats, and one doesn’t. One has a great stereo system, and one doesn’t. One has a sunroof and big wheels. They all do the same thing and get you where you are going, but they are all different cars.

Houses work the same way, with one difference that matters. In a car, most of what you are paying for is easy to see. In a house, a lot of it is hidden in the walls, the slab and the attic.

It is the same reason two sofas that look alike can be priced far apart. The question is whether it is built well underneath.

What Makes a Custom Home Worth the Premium

When I am asked what makes a custom home worth paying more for, my answer is attention to detail and quality. That means attention at every stage of the build, including the stages that get covered up.

It is also why the cost of a custom home is hard to quote from square footage alone. Our guide to cost per square foot to build a house in DFW explains how much the finishes and the build itself move the number, and the luxury custom home cost guide covers what changes at the high end.

How to See What’s Behind the Walls

The best time to see how a house is built is while it is being built. Walk through it before the insulation and drywall go in, and ask questions about what you see. A good builder will encourage anyone to walk through their homes to see the quality. If the home goes up too fast, you can’t see what’s going on in there.

Our article on the signs of a bad home builder covers what to look for on those walkthroughs, and the questions to ask your builder before signing help you check before the work starts.
