How to install a new Front Door – A step by step guide

If you have just purchased a door and frame from Ross’s Discount Home Centre, then you may be looking for guidance on how to go about installing it. This article will outline how to do just that.

First let me point out, when it comes to installing doors, you have two options. You can either hire a professional or you can do it yourself. As you’re come to this page I will assume you’re keen to give it a crack yourself.

Thankfully, our front doors are fairly straightforward to install. Simply, follow the following installation procedures properly and you should be able to install your door and frame without any professional help at all.

So, continue reading this article to discover the step by step guide to installing a new front door and frame.

Items you’ll need for the installation

  • Stanley knife
  • Electric saw
  • Measuring tape
  • Level
  • Caulk / Waterproof Sealant
  • Heavy Duty Nails
  • Hinges
  • Screws
  • Spray Foam
  • Shims / Wedge

Step 1: Remove your old door

Before you start, you need to first remove your old door. Start by tearing the brick moulding off the door frame with a Stanley knife. Next, remove the door frame with the help of an electric saw. Use the saw to cut through any nails and screws and take the frame out. Remove any broken bits that may be stuck in the door opening.

Step 2: Prepare the door opening

Now with your old door out of the way, you’ll have a gaping door opening which needs to be prepared. Measure the width in between the side jambs of the opening and the thickness of the wall. This opening should be wider as well as taller than the new front door that you’ll be installing. If the opening isn’t wide enough, use some tools to make it bigger. Always remember to check if the sills are level – if they aren’t, you’ll end up with a tilted door frame.

Step 3: Set your door frame into place

Setting your new door into place starts with caulking the entire perimeter of the door opening first. When caulking, make sure that the flat spots on the sill align with the beads of caulk. Once you’re done caulking, slowly set the door frame into place. If your measurements have been proper, the door frame will slide and fall into place.

Step 4: Fasten the door frame

Your new door may be up, but it is barely functional right now. You’ll need to fasten the door frame before you can start using your door. First of all, tack the top corners using heavy duty nails. Next, plumb all hinge sides, making sure that the jambs are level.

Slide a pair of shims behind the hinges that you’ve just plumbed and also on the opposite sidelights. Make sure that there is some gap around the door for it to open and secure the frame with the help of screws. Check to see if the frame securely holds the door, while the door also opens and closes smoothly.

Step 5: Add the finishing touches

Great! Now you have a door that is firmly fastened to the frame and working quite well. However, you’ll notice that the area around the shims looks a little unfinished. All you have to do is to seal these shim spaces with spray foam and cover with architraves.

Installing front doors could not be easier. Sure, you’ll have to do some heavy lifting when setting the door into place, but it’s nothing unmanageable. If you’re skilled with tools and you’ve handled other DIY projects, you’ll find that front door installation is fairly simple.
