Window Balance Repair in Florida
When windows won’t stay open or fall shut on their own, the balance mechanism has failed. Alpha Sliding Doors replaces window balances for all major brands across 13 Florida counties.
What Is Window Balance Repair?
Window balances are the mechanical systems that counterbalance the weight of the window sash, allowing it to stay in any open position. There are three main types used in Florida homes: block-and-tackle balances (most common in pre-2000 homes, use a coiled spring with a rope-and-pulley mechanism), spiral balances (a coiled rod with friction settings, used in many vinyl replacement windows), and constant-force balances (flat spring coils used in newer double-hung designs). When balances fail, windows either fall shut under their own weight (unsafe, can cause injury) or won’t open far enough to provide adequate ventilation.
Why Florida Doors Need This Service
Florida’s climate creates two distinct window balance failure patterns. Coastal and humid-area homes: spring corrosion is the primary failure mode. Salt and moisture enter the balance housing over time, oxidizing the spring and reducing its effective tension until the balance can no longer support the sash. Inland Central Florida: UV and heat cycling cause the plastic balance carriages to become brittle and crack, releasing the spring mechanism. In both cases, we see failures most commonly in homes over 15 years old, though poor-quality replacement windows (often installed during the 2000s construction boom) can fail in as little as 8–10 years.

How We Perform Window Balance Repair
Window balance replacement starts with identifying the balance type (block-and-tackle, spiral, or constant-force) and measuring the existing balance for an exact replacement match. The balance tension is calculated from the sash weight — an incorrectly sized balance will either hold the sash too high (over-tensioned) or fail to hold it at all (under-tensioned). The old balance is removed from the window jamb and the new one installed in the reverse order. For block-and-tackle systems, the spring tension is set before installation. For spiral balances, the rod is pre-tensioned to the correct number of turns for the sash weight. We test through the full range of motion and confirm the sash holds at multiple positions before finishing.

Frequently Asked Questions
Can I replace just one balance or do both need to be done at the same time?
Technically you can replace one balance, but we recommend doing both sides simultaneously. Balance tension decreases with age, so a new balance on one side paired with a worn balance on the other causes uneven lift — the sash will tilt and bind when operating. Replace both for smooth, long-term operation.
Are window balances different for impact windows?
Yes. Impact windows have heavier sashes than standard windows (the impact glass is thicker and heavier), requiring higher-tension balances. Using standard balances in an impact window won’t provide enough lift. We match balance tension to actual sash weight, not assumed weights.
My windows are old and I can’t find the balance part number. Can you still fix them?
Usually yes. We carry a range of balance sizes that fit the most common window brands in Florida homes — including legacy brands like Anderson (various models), PGT, and generic aluminum replacement windows from the 1980s-2000s. We measure and match on-site.
How long does balance replacement take?
Typically 30–45 minutes per window, including removal, installation, and testing. If you have multiple windows needing service, we can process several windows efficiently in a single visit.
