Here’s what we’ve learned about the most devastating window replacement mistakes – and exactly how to fix them!
Mistake #1: Measuring Your Window Opening Wrong
This single error destroys more window projects than any other mistake!
Inaccurate measurements create a domino effect of problems. Your beautiful new windows won’t fit properly, installation gets delayed, and you’ll pay extra for reordering. We’ve rescued countless Delmar homeowners from this expensive nightmare.
How to Fix It:
• Take multiple measurements at several locations – window openings aren’t always uniform
• Measure width, height, AND depth of the existing frame
• Account for any settling or structural changes in older Delmar homes
• Double-check every measurement before ordering
• Better yet – let our certified professionals handle the measuring!

Pro Tip: Delaware’s climate causes significant settling in homes built before 1990. Our team knows exactly how to account for these variations in Delmar properties.
Mistake #2: Ordering Windows with the Wrong Jamb Size
Your walls aren’t standard – and neither should your jambs be!
Many Delmar homes feature plaster walls, tongue-and-groove paneling, or thicker sheathing materials. Standard ½-inch drywall measurements won’t work for these unique wall constructions. Wrong jamb sizes create gaps, drafts, and installation nightmares.
The Smart Fix:
• Measure your finished wall thickness carefully
• Add that dimension to your jamb width specifications
• Consider historical building materials common in Delmar DE
• Consult with experienced local contractors who understand regional construction
Submit your information and we will give you a call to discuss your specific jamb requirements!
Mistake #3: Failing to Properly Secure Your Windows
Installing fasteners isn’t enough – your windows must be perfectly centered, level, plumb, and square! We’ve seen supposedly “professional” installations where windows leak, sag, or fail within months because of improper securing techniques.
The Professional Approach:
• Use precision levels during every step of installation
• Add shims strategically to achieve perfect alignment
• Install adequate fasteners at manufacturer-specified angles
• Verify alignment before permanent securing
• Never rush this critical step!

Family-Owned Expertise: Our installation teams have perfected these techniques through thousands of successful window replacements across Delaware.
Mistake #4: Using Wrong Spray Foam or Over-Applying
The wrong foam ruins everything!
High-expanding foam creates excessive pressure that bows window frames and prevents proper water drainage. We’ve torn out countless “professional” installations destroyed by improper foam application.
How We Do It Right:
• Use only manufacturer-recommended foam types
• Apply foam strategically – never fill the entire perimeter
• Avoid high-expanding foams that damage frames
• Protect finished surfaces during application
• Follow precise application techniques for optimal sealing

Mistake #5: Ignoring Manufacturer Instructions
Every window manufacturer has specific requirements for a reason!
Laboratory testing and field research determine these critical installation steps. Ignoring instructions voids warranties and compromises performance. Your investment deserves professional attention to every detail.
Our Professional Standard:
• Study manufacturer instructions before beginning any project
• Follow every specification for anchoring and finishing
• Maintain manufacturer certifications for major window brands
• Keep detailed installation records for warranty protection
• Guarantee compliance with all manufacturer requirements
Mistake #6: Neglecting Proper Flashing and Sealing
Water infiltration destroys Delmar homes faster than anything else!
Delaware’s humid climate and storm patterns demand exceptional flashing systems. Poor flashing at window heads and unsealed nailing fins create pathways for devastating water damage.
Professional Water Protection:
• Install rigid head flashing from project start
• Roll flashing tape properly over nailing fins
• Seal completely to window frames
• Account for Delaware’s specific weather challenges
• Complete all sealing before finishing installation

Climate Expertise: Our team understands exactly how Delaware weather affects window performance and designs installations accordingly.
Mistake #7: Ignoring Underlying Structural Issues
Installing beautiful new windows into damaged frames is like putting a band-aid on a broken bone!
Rot, mold, warping, and structural damage compromise your new windows from day one. We inspect thoroughly and address underlying problems before installation.
The Smart Improvements Difference:
• Complete structural inspection before beginning work
• Address rot, mold, and warping issues immediately
• Repair or replace damaged framing components
• Ensure optimal foundation for your new windows
• Guarantee long-term performance through proper preparation
