Stop Air and Pests From Sneaking Into Your Home

Insulation

When you're building a new house, it’s easy to miss small things that can make a big difference later. One of those things is air sneaking into your home. It might not seem like a big deal, but little drafts can make your home more expensive to heat or cool. They can even let in bugs or dirt.

There’s simple ways to stop this from happening, if you do it early.

Stop Air Leaks Before the Walls Go Up

Air gets into your home through small gaps. These gaps are usually around pipes, wires, or windows. You might not notice them at first, but they add up fast. Once the walls are finished, it’s harder and almost impossible to fix without an insane price tag.

Before the insulation goes in, walk through your house and look for these spots. Spray foam or caulk can seal them up quickly. This is one of those small jobs that saves money and keeps your home comfortable later.

Use a Sill Gasket at the Bottom of the Walls

There’s a common gap that often gets missed. It’s where the bottom of your outside walls meets the concrete or subfloor. This is a place where cold air and even bugs can sneak in.

To stop that, ask your builder to use a sill gasket. It’s a thin strip of foam that goes between the wall and the floor. Most builders use it already, but it’s worth checking to be sure. It’s a simple, low-cost fix that helps seal your home for life.

Don’t Forget About the Attic

Warm air rises. If your attic isn’t sealed well, heat can leak out through the ceiling. Recessed lights, attic doors, and vents are all places where air can escape.

Make sure the attic door has insulation. You can also ask for sealed light fixtures to keep warm air from slipping out.

Seal Around Windows and Doors

Windows and doors need to be installed the right way. Even small gaps around the sides can let in cold air. Seal these areas with tape or foam before the trim goes on.

Later on, good weather stripping helps keep air from leaking out when the windows and doors are closed.

Stop Air Leaks From The Beginning

Air leaks are hard to spot once the house is done but they’re easy to stop during construction. Talk to your builder about sealing the little gaps, using a sill gasket, and checking the attic and windows.
