That’s exactly why this Window Replacement Guide Every Buyer Wishes They Read Sooner exists, so you know what’s really happening and what steps to take long before a small issue becomes an expensive problem.
A homeowner in Webster Groves noticed recurring drafts in their 1950s ranch home. After a heavy storm, they spotted moisture along the interior sill. EBS found failing flashing and rotted exterior trim. The team replaced the damaged sections, installed new energy-efficient windows, and sealed the surrounding siding. The results? Warmer winters, cooler summers, lower energy bills, and the home’s curb appeal instantly improved.

What Window Replacement Means for St. Louis Homeowners
A Window Replacement Guide must begin with one simple truth: windows in St. Louis take a beating. Between hailstorms, sudden temperature swings, and decades-old homes across the region, small failures can quickly spread into other areas, rooflines, siding, gutters, and even masonry.
A well-executed window replacement helps you:
- Stop leaks before they affect walls, insulation, or brickwork
- Improve comfort by eliminating drafts
- Reduce energy loss (a must in St. Louis humidity and winters)
- Boost curb appeal, especially in older neighborhoods
- Prevent storm driven moisture from damaging adjacent siding or soffits
EBS looks at your entire exterior, not just windows. If the issue relates to roofing, siding, gutters, or masonry, their team catches it early and prevents additional structural wear.
Simple Checks You Can Do Before Calling EBS
1. Inspect for interior drafts
Move your hand around the edges of the window.
If you feel cool or warm air, call EBS for a sealing or replacement assessment.
2. Look for water stains or peeling paint
These indicate moisture intrusion.
If stains expand after each storm, call EBS.
3. Check exterior caulking from the ground
If you see cracks, gaps, or missing sections, don’t attempt ladder work.
Just contact EBS, they’ll fix it safely.
4. window test “stickiness.”
Open and close the window.
If it jams or grinds: time for a professional inspection.

Frequently Asked Questions
