How To Fit A Garage Door

If you are thinking about building a garage extension or replacing the current garage door then this guide will tell you everything you need to know about installing a garage door.


Much like Windows a garage door sales company will often provide everything which includes removal of your old door delivery of the new door and installation. However, you can save a great deal of money if you choose to do the installation yourself because you can purchase the garage door for a much better price.


Sectional Garage DoorThat first impression of a garage door is that they are going to be extremely heavy relatively complicated and very difficult to fit. If you are considering fitting a sectional garage door which are the ones which travel on tracks before rolling down across the doorway (as shown in picture) then this guide exactly what you need.

If you are replacing current garage door that is fitted with a torsion spring, then I highly recommend that you call a professional to at least help you remove the spring. The reason for this is they are tightened to extreme pressure and if removed incorrectly can cause serious injury.

Obviously each and every garage door will have its own installation instructions which you should follow. The guide below here will show you the general standards for the fitting of a sectional garage door.


Step 1

The first thing you need to do is attach weather stripping to the bottom edge of the first panel of the garage door. It’s not only protects the bottom of the garage from scraping on the ground that it also prevents the intrusion of water and wind into your garage.

Seat the first panel into the doorway and hold in place by using nails hammered in a blank or (not into the garage door itself), they are simply used to hold door into position. If they haven’t already been done at this point you need to attach the hinges to the top edge of the door.


Step 2

Your garage door will come with the tracks necessary to hold it as it runs. Each manufacturer will have different specifications so you will need to follow the instructions given with your garage door. Assemble the tracks on the ground rather than trying to assemble them by screwing them in place.


Step 3

These are attached on the garage door section itself as well as the wall mounted brackets. They will usually have specified layouts which will be included in the manufacturer’s instructions.) Have been installed simply slide the door section on to the track and rollers. Do one side a time until it is secured in place.


Step 4

The first section should now be in place so the trick is to install the rollers for the second section. You will go need some help in this mainly to help lift the section into place and slip into the rollers. Once this is done simply fast as the hinges that connect the first section on to the second. These are usually done with standard screws however I recommend using electric screwdriver for this as there will be a lot of screws and will be very time-consuming doing it manually.


Step 5

At this point you’re going to install the third section using the second same procedure as is done for the first two. Once you’ve done this you should check the levels and tracks are all in place. When they are seated as they should be fast on the top plates of both tracks to the wall. You need to ensure that these brackets are securely fastened because the garage doors are extremely heavy and will exert a lot of pressure on these brackets. You will also need to screw on the jamb brackets securely against the frame. However for these brackets do not super tighten screws because you may need to adjust it later.


Step 6

Now you need to pick up the tracks you construct it earlier and connect the curved track as shown in your manufacturer’s instructions. Make sure the pieces are tightly bolted together. Again this is another task where you could do with a second person helping you or you can rest the curved piece on the top of a ladder. Once everything has been tightened up and in place you need to check that everything is level. Once it is you can cut the rear hanger of the track to the always allow a little extra as once it’s cut you can’t put it back.

Tracks will also need to be secured with track hangers. However when you install these you need to be sure that you screw them into firm joists or solid framing. There’s no point screwing them into a plasterboard ceiling as the garage door weight will simply pull it down.

Once you are happy that the door is secured in place and can move freely then you will need to follow your manufacturer’s instructions to make the correct adjustments to the torsion bar. This is the spring element which will help you lift the entire door with the aid of the spring.
