New Construction Defects: Poor Window Sealing in Las Vegas Homes

When buying a brand-new home, you expect everything to be built correctly and ready to last. Unfortunately, even in new construction, defects can appear that may cause long-term issues if left unaddressed. One common problem I’ve found during inspections in Las Vegas is poor sealing between windows and stucco.

Why Is Window Sealing Important?

Windows are a critical part of a home’s exterior, protecting against wind, dust, rain, and extreme temperatures. If there’s a gap between the window frame and the stucco, it creates an opening where moisture and air can get inside. Over time, this can lead to:

• Water damage – Rain can seep into the gap, potentially causing mold, rot, or damage to interior walls.

• Energy loss – Gaps allow air to escape, making it harder to keep your home cool in the summer and warm in the winter, leading to higher energy bills.

• Cracking and deterioration – Without a proper seal, the stucco around the window can become weak and start to crack.

What I Found During a Recent Inspection

During a recent new home inspection in Las Vegas, I noticed that the stucco and window frames were separating, leaving visible gaps. This is a common issue when proper sealing techniques aren’t used during construction. The builder should have applied a flexible, weatherproof caulking material to seal the gap between the stucco and the window frame. Without this, the home is more vulnerable to the elements.

What Homebuyers Should Do

If you’re buying a new construction home, it’s important to inspect the sealing around all windows. Look for gaps, cracks, or areas where the materials appear to be pulling apart. If you see this issue, ask the builder to apply high-quality caulking to improve the seal and prevent future problems.

Why a New Home Inspection Matters

Even in new construction, mistakes happen. A professional home inspection can help identify defects like poor window sealing before you move in. Addressing these issues early ensures your home is protected and built to last.

If you’re purchasing a new home in Las Vegas, schedule an inspection with a trusted new build home inspector to catch problems before they become costly repairs.
