As commercial and residential garage door service professionals, we’ve pretty much dealt with every issue you can think of when it comes to garage door repair. Even still, there are sometimes issues that continue to surprise us, like the tiny insect nest growing on the photo eye sensor or the tennis ball that somehow managed to knock the door entirely off its track. Even though these issues are uncommon, it’s nothing that garage door service professionals like us can’t handle!
6.8 Properly tightened screws will loosen with less than a turn. Once you loosen a set screw, keep at least one bar in the cone AT ALL TIMES until the spring is fully unwound. Many cones have been over-tightened. The spring may unwind 1/4 turn and not unwind any more until one of the set screws is loosened some more. You may need to completely remove the set screws. The shaft may be distorted and the cone still may not unwind at all.

Since garage doors come in all weights and sizes, the right springs need to be installed in order to properly balance the door. If a technician puts the wrong spring on your door, not only will this damage your garage door system, but it will cause the garage door opener to do more work than it was built to do. This is why Precision technicians only install the right springs for the door's weight and check their work by performing a balance test.
Thank you, thank you, thank you for sharing your knowledge. I just replaced our shower cartridge and our leak is FIXED!!!!!!! Your instructional was clear and concise. I did purchase 2 cartridges first, because I did not know the type it was and could not pull it out without the plastic cover it comes with. Fortunately, it was one of the two. By the way I'm a 63 year old woman. If I can do it, anyone with internet and a little patience and an hour can do it.....
If your garage door is equipped with extension springs (usually seen on single car garages), the cable and pulley might be hanging down when the spring break's. Extension springs use a two pulley system on each side of the door to lift the garage door up and down. When the spring break's everything goes haywire, causing the cables to become twisted or even frayed when they catch on the metal edge of the track. There is a lot of force being released when a garage door spring breaks.
Most garage doors have two springs installed at the same time, when one breaks it's safe to say the second spring's life expectancy has just about expired. In order to save you from future inconvenience, unsafe garage door practices, and damaging your garage door opener, Precision will usually recommend to replace both springs. If you've had the same tires on your car for a while and one blows out while you're driving, wouldn't you replace them both? It's extremely important to properly maintain equipment such as garage doors and automobiles.
The electronics should also be inspected before or after investing in the cost of replacing the garage door panel to make sure your door will operate properly. The sensors prevent the door from closing on someone's foot or a pet. If they don't work, someone could be injured. Also check to make sure the door opener works, since you could otherwise be locked out of your garage.

I've been watching TOH since 1981. I just happened to stumble across it on PBS during a repeat of the second season, was instantly taken with it - and, hooked-for-good. That particular show/season (the Newton/ H. H. Richardson House - 1981) remains my favorite. Also, I happened to meet Norm quite a few years back and he mentioned it as being his favorite, as well - all-the-more reason for me to have fond memories of it. If I were to pick more 'favorites' from the 'Bob-era', 'Steve-era' and 'Kevin-era' they would be: 'Bob-era' - the Lexington Bed & Breakfast (1988) and the In-and-Around Boston shows (1984); 'Steve-era' - the Concord Barn (Wickwire House - 1989), the Wayland House (Kirkside - 1991)) and the Jamaica Plain House (1990); 'Kevin-era' - the Cambridge House (2005), the Newton Shingle-style House (2007) and the Detroit Houses (2017).p.s. - I've very much enjoyed the times that the show has gone back and looked at previous projects. It's always nice to see how the home - and homeowners - have done over time. Thank you! https://www.youtube.com/watch?v=Z_eZc-kh40c&app=desktop
Align the upper roller tracks by carefully lifting the door halfway. Lock it in place with two locking pliers, and install the supporting brackets on the back of the rails using 1-1/4 in. perforated angle iron (available at home centers and hardware stores). Install 1-1/2 x 1/4 in. stop bolts, with the threads to the inside of the track, at the end of each upper track.
However, if you are confident that you don’t just need new batteries, make sure to call a professional. A service person with a lot of experience will be able to look at the problem and quickly diagnose the issue, saving you precious time. Again, while you may be able to save money in the short term by taking a day off and troubleshooting the problem yourself, the amount of energy and time lost as you search out the issue will quickly surpass the cost of a professional repair.

9.9 Go to the other side of the garage door and insert the end of the cable into the drum. Rotate the drum until the cable is tight. Slide the drum against the bearing and push the shaft to the right. The marks should line up. If they don't, figure out why and correct the problem. It could be a stuck cable, the garage floor may have shifted, or the vertical angle that helps support the bearing plate may have loosened and shifted. Many garage doors have been installed with a gap between a drum and a bearing plate. The cable drums should always be flush against the race of the bearings.
If you've installed a replacement door or two around your home, it seems pretty simple -- all it takes is tightening a couple of screws and you're done. Installing t­he largest door in your house, however, is not quite so simple. Garage door in­stallation, whether manual or automatic, can be difficult and dangerous. Manual garage door installation is much easier than automatic garage door installation, but the one you choose generally depends on what kind of door you have.
