Start With The Home, Not The Brochure
The best replacement window is rarely the one with the flashiest brochure. It is the one that fits the house, the climate, and the way the room is actually used.
That matters in Montgomery County because homes here cover a lot of ground. You may be working with a 1960s split-level in Rockville, a brick colonial, or a newer build with larger glass openings and stricter HOA rules. The right window for one of those homes can be a poor fit for another.

If a window looks fine but leaks air, traps condensation, or flexes under heat, it will not last long in this climate.
Before comparing brands, focus on the frame material, the glass package, the operating style, and the installation itself. Those four decisions do most of the work.
An experienced company can confirm the cause with a quick inspection.
