The same hardware, the same failures, at a smaller scale. Windows get ignored until every one in the house is stuck.
Horizontal windows are miniature versions of your patio door and they fail identically. Small rollers or glide pads wear down, the track fills with grit and salt, the sash drops slightly, and the latch stops meeting its strike. The fix is the same sequence too: clean the track, replace the hardware, reset the sash so it sits square, then re-align the latch.
Vertical sashes are carried by balances, either a coiled spring device or a block-and-tackle assembly hidden in the jamb. When a balance fails, the window will not hold its position. It slams down when you let go, or it takes serious effort to lift.
Balances are matched to the weight and height of the specific sash, which is why a generic replacement usually feels wrong. We identify what your window takes and fit the correct rating.
A window that rattles in wind is not sealing, and a latch that no longer engages is both a security and a weather problem. Both usually trace back to the sash sitting slightly out of position rather than to the latch itself, so we correct the alignment first and replace the hardware second.
Water showing up at a window sill is worth diagnosing carefully, because the window is not always the source. In a lot of Florida homes the actual failure is the flashing or the stucco above, and the water simply runs down and appears at the first horizontal surface it meets.
We check the obvious window causes first, hardened weatherstrip, blocked weep holes, failed perimeter sealant, and we will tell you honestly if what you have is a wall problem rather than a window problem. Resealing a window that was never leaking is a waste of your money.
Practical tip: if several windows in one house have gone stiff at the same time, it is almost always accumulated track debris rather than simultaneous hardware failure. A vacuum, a wash, and dry silicone lubricant on all of them is a good afternoon's work and often solves it.
