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. One property might be a 1960s split-level in Rockville, another a brick colonial, and another a newer home with larger openings and HOA approvals to consider. A window that works well in one of those homes can be the wrong choice in another.

If a window looks good but leaks air, collects condensation, or bows under heat, it will not hold up here for long.
Before comparing brands, focus on the frame material, the glass package, the operating style, and the installation itself. Those four choices drive most of the performance.
An experienced company can confirm the cause with a quick inspection.
