Oconomowoc is a Lake Country city in ZIP 53066. Its garage doors range from older setups on extension springs to newer insulated doors on belt-drive openers.
Look above your door. A torsion spring sits on a steel bar right over the opening. Extension springs run along each side, above the flat part of the track, and stretch when the door closes. Older doors more often use extension springs. Each one should have a safety cable through its center, so it cannot whip loose if it breaks.
Extension springs often break without warning, and more of them break in cold weather. If one breaks and the door comes off its track, stop using it and call us. Most torsion springs are rated around 10,000 cycles, roughly five to seven years at four to six cycles a day. Our post on torsion and extension springs compares the two.
Wood doors can split, swell at the joints, or rot along the bottom rail after years of freeze and thaw. We replace springs and worn hardware on wood doors. When a wood door is past saving, we can show you Haas and C.H.I. doors with a similar look.
A lightning storm can send a surge through the house wiring, and it can damage the logic board in an opener. A board that fails leaves the opener dead or acting strange. The fix is a new board or, on an older unit, a new belt-drive opener. A plug-in surge protector at the ceiling outlet can help. Do not use a power strip on a cord.
Opener repair usually runs $180 to $440, and a full belt-drive replacement usually runs $480 to $780. We install LiftMaster openers and repair most major brands. Read more on our opener repair page.
Road salt, meltwater and damp garages rust bare steel over time. That includes springs, cables, and the bottom edge of steel panels. If you see rust flakes under the springs or orange streaks on the bottom section, mention it when you call. A tune-up every two years checks spring tension, cables, and rollers, and fall is a good time for one.
The estimate is free. A single torsion spring usually runs $220 to $320, and a matched pair $320 to $420. Extension-spring swaps usually run $180 to $280. A new 16-foot insulated steel door installed usually runs $1,400 to $2,400. The final number depends on your door and the parts it needs. See the full cost guide.
When you call, tell us what the door is doing. A dead opener, a door that will not lift, a loud bang, or a door hanging crooked each point to different parts. To book a visit, go to our Oconomowoc service page or contact us.
