Garage Door Bottom Seal Replacement in Hillcrest Village
There are mouse droppings along the wall behind the recycling bins, and at one bottom corner of the door the vinyl has a neat chewed notch the width of a thumb. Something has found its way in for the winter.
Garage Door Bottom Seal Replacement
In plain words
Not every gap under a garage door is the seal, so the service begins with finding out what the gap is. A strip of light the whole width usually means a seal that has flattened or hardened. A gap at one corner only points to a door hanging out of level or a slab that has settled there. A gap in the middle suggests a bowed bottom section or a crowned floor. Reading these before choosing a seal means the new strip is sized to fill the space that is really there, and any door or floor issue is named and dealt with rather than hidden behind a thicker bulb.
How the visit goesAfter a spring rain there is a puddle inside the door that reaches the tires. The driveway slopes toward the garage, the slab has a low corner, and the flattened old seal is not making up the difference.

How the visit goes
Is the door hanging level?
A gap that is wider at one corner is often the door rather than the seal. The technician checks that the door sits square in the opening by comparing the bottom edge to the floor at both ends and looking at how each lift cable wraps its drum. A stretched cable, a drum that has crept on its shaft or uneven spring tension drops one corner a centimetre or two, and setting the door level is what closes that wedge. If the door is out of level, the adjustment is explained as its own item and done first, and the seal is then sized to the gap that remains. Getting the order right saves fitting a seal twice.
Adding a threshold seal on a difficult floor
Where the slab slopes toward the garage or has a dished edge, a threshold seal glued to the floor follows the existing contour and gives the bottom strip a raised, consistent edge to meet, rather than levelling the floor itself. The floor line is marked with the door closed, the concrete is swept and cleaned for the adhesive, and the threshold is dry-fitted and trimmed against each jamb. Adhesive is laid along the underside, the threshold pressed down, and the door lowered onto it while it sets. The result is a small raised lip on the outside that turns water back to the driveway and a bottom seal that lands on a consistent edge along its length.
A door that meets the floor in one line
The first thing you notice is the absence of daylight. With the door closed and the lights off, the floor line is dark from one jamb to the other, and the draft that used to move across the floor is much reduced. The door lands softly, because the opener now stops when the seal is gently compressed rather than driving the section into the concrete. Leaves, grit and drifting snow are kept out far more often. If you crouch and look, the new bulb sits evenly along the slab, filling the low corner the old strip used to hover above.

What affects the quote
Same fees day, night or weekend
1Opener adjustment
Resetting the down limit and force and repeating the reversing test after a taller seal is fitted is a short step that the quote names whenever the door has an opener.
2Season and conditions
A seal frozen to the slab, ice at the threshold or working in deep cold adds time for freeing the old strip, clearing the line and keeping the new roll warm enough to feed.
3Retainer replacement
If the aluminum or plastic retainer is bent, spread open or corroded, a new extrusion, fasteners and the time to fit it straight along the rail are added as their own line.
Garage Door Bottom Seal Replacement: questions
Will I need a new retainer as well as a seal?
Only if the existing one is damaged, and most are reused. A retainer that is straight, tight to the rail and free of heavy corrosion stays. One that has been kinked by a bumper or shovel, spread open so the seal slips out, or eaten by salt is replaced with a matching aluminum extrusion so the new seal seats properly. The inspection at the start of the visit settles which applies.
How do I look after the new seal?
Wipe it clean of salt and grit a few times a year, and give it a light coat of silicone spray each autumn so meltwater has nothing to bond to. Keep petroleum products and solvents away from it, since they soften vinyl. Clear ice and packed snow from the threshold before running the door in winter. Once a season, look under the closed door for daylight. That is the whole routine.
My garage floor is uneven. What are the options?
Three, and they can be combined. A taller bulb-style seal compresses more and follows a modest dip or crown. A threshold seal fixed to the floor follows the slab's existing contour and gives the door a raised, consistent line to land on where it is dished or sloped. And where the floor has heaved or broken up badly, grinding or patching the concrete is a separate job that makes any seal perform better. The gap map from the first look shows which applies.
