Installing the side entrance door – the step by step guide

Installing The Side Entrance Door

Preparing the side entrance door installation correctly is how the door installation succeeds.

Installing a side entrance door is also a big challenge for a do-it-yourselfer. However, it is always worthwhile if you benefit from more excellent burglar resistance and better thermal insulation afterward. Of course, the visual aspects also play an essential role. With our tips from a professional, you can then achieve a successful result:

  1. Have all materials and tools ready.
  2. Work best in pairs, so the installation is more accessible and you save time.
  3. Carry out the preparation steps carefully.

Mounting material

  • New side entrance door
  • Mounting wedges/washers
  • Decompression sealing tape
  • Window frame screws
  • Mounting foam
  • PU cleaner/remover
  • Mortar, adhesive plaster, putty
  • Silicone/acrylic

Tools

  • Folding rule
  • Spirit level
  • Cordless screwdriver
  • Impact drill
  • Wood/metal/stone drill
  • Cartridge press
  • Trowel
  • Screwdriver
  • Safety goggles and gloves
  • Cutter knife

General preparations:


  1. Take measurements and check

Before you start the installation, compare the dimensions of the new side door with those of the wall opening. If the fit is correct, you can begin.


  1. Renovation: removal of the old side entrance door

When renovating, the old door must first be removed. Please read our guide to removing the side door to find out how to dismantle it.


  1. Prepare the working surface

Check that the surface is free of dirt and dust particles. Before new installation, unevenness in the reveal must be leveled.


  1. Inventory check

You can start right away. Are all tools and building materials present? Check for completeness. Our checklist will help you keep track of everything.


  1. Safety

Safety first! Therefore, wear protective gloves and goggles during the entire work process. Work in pairs.


  1. Checklist and instructions

Always keep the instructions handy to verify your work steps; the checklist helps not forget any essential tools or materials.

Suitable ASSEMBLY MATERIALS AND SETTING TOOLS

Overview: Sealing levels and types on the window

Careful sealing of the connection between the front door and the wall reveals essential for later functionality and durability. A distinction is made between three sealing levels that you should take into account:

Outer sealing level

A weatherproof seal is essential for the exterior window joint because it is permanently exposed to the weather. A sealant open to diffusion is recommended to ensure that any moisture that may have penetrated can still escape.

Middle sealing level

Good thermal insulation and reliable soundproofing are ensured at the middle level between the window and the masonry. An expanding PU foam is often used here.

Inner sealing level

The insulation of the inner building connection joint must be impervious to both water and air. This prevents warm, moist room air from entering the joint and thus promoting mold growth.

Multifunctional tapes enable 3-level sealing with just one product. This means much faster installation, easy handling, and only one tape for all functional areas.

Preparations at the side entrance door:


  1. Mount door fitting

For transportation, the side door is locked. Place the door fitting on the pre-drilled holes of the door leaf and mount it. Then insert the locking cylinder to be able to open the door leaf.


  1. Unhook side door leaf

Loosen the securing screws of the door hinges. The structure of the door hinges differs depending on the manufacturer. Read in our guide on Adjusting the side door to find out which type your door hinges correspond to and how to loosen them easily.


  1. Remove the protective film of the frame.

You can carefully remove the protective foil from the frame when everything is prepared. Always place the frame and sash on a soft surface to avoid scratches or other damage.


  1. Attach sealing tapes

To fill all three sealing levels in one step, we recommend so-called 3-1 sealing tapes. They are glued to the sides and top of the frame and inserted with it into the wall reveal. For more information, see The sealing front door.

Five steps to install a side entrance door

 


  1. Insert and fix

Check again whether all preparations have been carried out on the side entrance door and the wall reveal. Does everything fit? Then you are ready to start. Lift the frame in pairs and carefully place it in the wall opening.

Fix the position with mounting wedges, pressure-resistant washers, or a mounting pad.


  1. Aligning the frame

The frame is aligned at three points: horizontally, vertically, and in line. Use a level and pressure-resistant shim to precisely control the position. Ensure an equal circumferential distance to the masonry. Also, check the floor level and simulate the path of the door leaf when opening so that it does not drag later.

Tip: Place the spirit level against the frame from the inside to measure the alignment. This will allow you to check whether the frame is straight or leaning outward or inward.


  1. Drilling and screwing

Drill holes in the frame using an iron drill. Ensure you have the proper distance to the frame corners and between the holes. Then the wall holes are set through the same holes (masonry drill), and the frame is screwed without tension with mounting screws.

Before screwing, the door leaf should be hung on a trial basis, and its functioning during opening and closing should be checked. Use a spirit level to limit that nothing has shifted during hanging before fastening the frame. The mounting wedges can now be removed.

Our tip: Order your side entrance door with pre-drilled mounting holes right away at Parlun.

Start screwing by tightening the top screw on the hinge and closing the side. After you have aligned the frame on the hinge side, the remaining screw connections on the hinge side follow. To correct the frame alignment later, if necessary, the other screw connections are only made after the sash has been hung and checked for proper functioning.


  1. Foaming and sealing

Once the fit is perfect, you can seal the gaps. If you have used sealing tape, wait until it has fully expanded. You can then fill the gaps in the wall opening with installation foam or seal with sealant or cover strips, depending on the type of installation. Before doing so, tape the adjacent materials to protect them from contamination.

Once the foam has fully cured (please follow the manufacturer’s instructions), remove the excess material and the protective adhesive tape. Minor stains can be easily removed with PU cleaner.


  1. Hang and adjust the side entrance door leaf

Again, work in pairs to lift the door sash and carefully place it in the frame. Screw the threshold to the floor. Be sure to shim the door sill to not bend under load.

Carefully align the sash with the appropriate adjustment tool to function optimally and not jam. Also, check the closing function. For more information, see our instructions for adjusting the side entrance door. Finally, attach the water protection caps to the outer frame.
