Garage Door Tune-Up in Craighurst
Halfway up, the door shudders. The sections seem to catch for a moment, the whole assembly shakes, then it carries on as if nothing happened.
Garage Door Tune-Up
In plain words
Garage doors here live through a wide swing of seasons, and a tune-up before winter pays for itself in smooth mornings. Cold thickens tired lubricant and stiffens steel, so a door that ran fine in September can groan in January. Rubber seals go hard, meltwater freezes the bottom seal to the slab, and road salt works on the lower hardware. The fall visit replaces old lubricant with a low-temperature product, treats the seals with silicone and checks the threshold, since a door frozen to the slab should be freed and dried rather than forced by the opener.
How the visit goesYou pulled the red cord to lift the door by hand during a power cut and it felt like lifting a car. The opener has been doing all the work and grumbling about it, and you are not sure how long that can go on.

How the visit goes
The opener's connections and safety devices
The opener is inspected as part of the door system, not as a separate appliance. The technician checks that the rail is firmly attached at the header and the ceiling hangers, that the chain or belt has the right sag, that the trolley and door arm are not worn or bent, and that the arm sits at the angle the manufacturer intends when the door is closed. Photo-eyes are located and their height measured, since the beam belongs no higher than about 15 centimetres off the floor. Indicator lights are read: steady means aligned, blinking means the pair are not seeing each other. The wall control and the red manual release are confirmed present and reachable.
Seals and the threshold
Rubber and vinyl get a silicone spray, never a petroleum product, which attacks the material. A bottom seal that is torn or has flattened can be replaced in the same visit if stock is on hand: the old length is drawn out of the retainer, the retainer is cleaned, and the new astragal is fed in and trimmed to width. Jamb and header weatherstrip that has gone hard or split is renewed so the door closes against a flexible edge and stops rattling in wind. Where the threshold holds water, the technician points out the low spot and suggests keeping it clear of ice, since a seal frozen to the slab is the usual winter casualty.
Knowing what to listen for next
Part of the handover is a short lesson in the door's language, so the next change registers. A squeak returning means the hinge pins want lubricant. A new rattle at the top of travel means a screw is loosening and is worth a look. A door that starts to sink when lifted by hand is springs losing tension. A loud bang from the garage with the door then feeling very heavy is a broken spring, and the door stays closed until it is replaced. A door that reverses on its own with no obstruction is a sensor or force issue. With these signs in mind you can describe a problem precisely and decide whether it needs a call.

What affects the quote
Same fees day, night or weekend
1Photo-eye and wiring work
Cleaning and realigning sensors is routine. A bent bracket, a chafed wire or a sensor that has failed means a part or a rewire, which is named separately.
2Torsion or extension springs
Torsion springs above the header and extension springs beside the tracks are inspected differently, and extension systems have pulleys and safety cables that add items to the checklist.
3Door construction and weight
A heavy wood or insulated steel door works its hardware harder than a light aluminum one, and the balance check and fastener work take a little longer on the heavier door.
Garage Door Tune-Up: questions
What is the balance test and why does it matter so much?
With the door closed, the opener is disconnected using the red release handle and the door is lifted by hand. A balanced door rises with modest effort, stays fully open and holds still about a metre off the floor. The springs are meant to carry nearly all the weight so the opener only guides the door. A heavy or sinking door means the opener is lifting weight it was not built to lift, wearing its gear and making the reversal system less reliable.
Does road salt harm the door?
Salt carried in on tires and shovelled snow settles on the lowest hardware: the bottom brackets, the lower track, the bottom roller stems and fixture bolts. Those are the parts that carry the door's weight, so corrosion there matters. Rinsing the lower hardware and the inside face of the bottom section after winter, keeping the floor by the tracks swept, and having the bottom brackets looked at each spring keeps salt from becoming a structural problem.
Can you replace my rollers with quieter ones during the tune-up?
Often, yes, if you decide you want them and stock is on the truck. Nylon rollers with sealed bearings run noticeably quieter than plain steel rollers and need no lubricant. Rollers on the middle sections can be changed with the door clamped in the track; the bottom rollers sit in the bottom brackets, which hold spring tension, and are changed as part of a separate job. The technician can tell you how many are worn and what the change would involve.
