These are the muscles behind your door. They hold tension and help lift everything smoothly — until, eventually, they don’t. When they break, you’ll either hear a loud snap or notice your door just won’t budge. In worse cases, the door might slam down out of nowhere. We take out the busted spring, drop in a premium replacement, and test everything till it’s moving like it should.

These springs stretch and contract every single time your door moves. That daily action adds up. Over time, they start to wear thin, and before you know it, the door’s tilting or acting up. If your door’s looking off-balance or jerky when it opens, those extension springs may be the issue. We replace them fast before they cause more damage down the line.

 Let’s be real — Northfield winters aren’t easy on anything metal. Snow, cold, moisture — it all adds up. Springs can start rusting from the inside out, which weakens them without you even noticing. We check for signs of corrosion, even if they’re small, and swap out any springs that look close to failing. Better safe than stuck.

​ Too much tension and the door fights you every time it moves. Too little, and it won’t stay up. Either way, it’s not right. If your door slams shut or won’t hold position, it could just be a tension issue. We adjust the balance on the spot and get everything aligned again — no guesswork, no trial-and-error.
