Here’s a truth about the Charlotte construction market that most homeowners never hear: the biggest quality issue isn’t the materials going into your home. It’s how they’re installed.
The Problem
Every product that goes into your home — windows, roofing, siding, waterproofing membranes, insulation, flashing tape — comes with detailed manufacturer installation guides. These aren’t suggestions. They’re engineered specifications that define exactly how the product performs and what conditions must be met for the warranty to be valid.
The reality on most job sites? Trades install products the way they’ve always done it. Techniques passed down from crew to crew that may have been fine 20 years ago but don’t account for how modern materials and assemblies work together. The result is products installed incorrectly, warranties voided before the homeowner moves in, and failures that show up 3–7 years later.
Why This Happens
It’s not malicious. Most trade partners are skilled craftspeople who take pride in their work. The problem is inertia. When a technique has worked for a decade, there’s no obvious reason to change — until it fails. And modern wall assemblies, window systems, and waterproofing products have changed significantly in the last 10 years. What worked in 2015 doesn’t necessarily work with 2026 products.
How We Handle It
At Royal Building Group, every trade partner on our jobs installs per the manufacturer’s current specifications. Period. This means:
- We read the manuals.Before a product goes on any of our jobs, we review the current installation guide. Not the version from three years ago — the current one.
- We communicate expectations. Trade partners get specific installation requirements before they start. Not after we find a problem.
- We inspect against the spec.Our field checks reference the manufacturer’s documentation, not just visual appearance. A window can look perfectly installed and still be flashed incorrectly.
- We push back.When a trade says “we’ve always done it this way,” we show them the manual. It’s a constant battle, but it’s one we fight on every job because the homeowner deserves it.
Why It Matters for Your Warranty
Most manufacturers are explicit: install the product outside their specifications and the warranty is void. That premium window system you paid $80,000 for? If the flashing wasn’t installed per spec, the manufacturer owes you nothing when it leaks. The liability falls to the builder — or worse, to you.
What to Ask Your Builder
Before you sign a contract, ask:
- Do you require trade partners to follow manufacturer installation guides?
- How do you verify compliance during construction?
- What happens when a trade partner’s standard practice conflicts with the manufacturer’s specification?
The answer to these questions will tell you more about a builder’s quality standards than any photo gallery ever could.
