Installing a door viewer (peephole) in a metal door

Filed under: House Remodelling — Gilles @ 7:29 am

A door viewer is installed in a metal door.

Skill Level: 1 (Easy)

Time Taken: Approximately 20 minutes
A door viewer is a cheap and easy way to enhance security at your front door. These simples steps show how to add one to a metal front door.

Left: The door viewer to install. It can fit doors from 1 3/4” to 2” thick and offers a viewing angle of 200 degrees. The wider the angle, the better.

It is approved for installation in fire rated doors. I purchased it at a local home center for less than $5. 

Right: I started the installation by marking the center of the door viewer with a pencil. It is centered horizontally and 5′ high from the finished floor.

Anyone old enough to answer the door should be able to use the door viewer and 5′ from the floor allows a teenager to use the device without problems. 

Left: On the inside of the door, I drilled a 1/8” pilot hole at the location I just marked.

I made sure to drill through one side of the door only. This technique eliminates potential material chipping on the edges of the hole on the other side of the door.

Right: Using a 9/16” metal bit, I drilled over the pilot hole.

With the 9/16” bit, I drilled through the insulation located in between the two sides of the metal door and went far enough to make a dent visible from the outside of the door. I did not actually drill the hole completely.

Left: From the outside, I drilled a 1/8” pilot hole over the dent made in the previous step.

 

Right: I used the 9/16” bit to drill the complete hole on the outside of the door.

Left: I applied a bead of siliconized exterior latex caulk around the outside end of the hole.

 

Right: I inserted the outside part of the door viewer and pressed it into the bead of caulk.

Left: I threaded the inside piece of the door viewer in the outside piece, through the hole.

Normally, I would have applied expanding insulating foam in the hole before tightening the door viewer but in this case, the bead of caulk and the insulation inside the door were sufficient.

Right: I finished screwing the inside part. The last quarter turn was done by pushing the assembly using a large flat screwdriver.

I could also have used the back of the blade of a large kitchen knife. It is a little easier to tighten the assembly because the blade acts on both rabets instead of one but you need to be careful not to cut yourself with the blade.

Finally, I removed all excess caulk which oozed aroud the outside part of the door viewer and smoothed the bead.

 

Tools Used:

  • Corded Drill 
  • Tape Measure
  • Caulking Gun

Materials Used:

  • Door Viewer 
  • Exterior Siliconized Latex Caulk

Finishing a garage window redux

Filed under: House Remodelling — Gilles @ 6:36 am

 
In a previous entry, I described how I refinished a garage window step by step. Today, I have put the finishing touches to the project: third drywall coat, caulk aroud the window, a few coats of paint and a Basic Blendz mini blind:

 

And here is a detail of the bottom left corner:

Weatherstripping an entry door

Filed under: House Remodelling — Gilles @ 11:53 pm

 
You can save up to 15% on your energy bill by weatherstripping openings (doors, windows and electrical outlets on exterior walls).
 
In theory, weatherstripping is simple: it is about preventing cold air from coming inside (or warm air to go outside). In practice, very few people take the time to think about the best way to weatherproof a specific opening and slap the first piece of foam then can put their hands on. This translates into poor insulation which does not last very long – essentially just like if there was no weatherstripping.
 
My main entry door used to be the perfect example of this. The previous owner definitely slapped on some pieces of foam but they were barely sealing the gap. This was not a very lasting job (you can see the foam leaving after a few months of service) and made the door difficult to close.

 Here is how you can achieve a great and long lasting weatherstripping.

Stop and think!

Weatherstripping is 95% design and 5% actual installation. Resist the urge of picking up a random gasket next time you visit a hardware store. Avoid glueing, nailing or screwing anything before you have assessed the situation and proven that there is no other solution.

The best way to figure out which weatherstripping product will best seal is to inspect the opening for built-in weatherstripping holders. Most doors manufactured in the last 30 years have been designed with weatherstripping in mind and most of them have a gasket holder. Hardware store (physical and internet stores) sell a large selection of gaskets designed for most popular doors. Use them because they’ll give the best seal, hold well and last long.

In my case, the built-in mecanism is a long opening designed to receive a vinyl clad gasket. If the previous owner looked at the dor jamb for 15 seconds, he would have noticed it and installed the right gasket. The left picture below is not from the same door but has a very similar kerf for gasket. The right picture shows the section of the adequate vinyl clad which will fit in the opening and seal the door appropriately.

 

The white part is made out of rigid pastic and goes in the kerf while the v-shapped black part get compressed when the door closes and seals the gap.

If there is no obvious holder for weatherstripping and there is already a weatherstripping solution, remove the old weatherstripping. The holder may hide behind existing weatherstripping. Sometimes, holders may hide behind several coats of paint. If you can’t find any holder, try to find the name of the manufacturer and look up online for the best gasket type. It is easier than it sounds.

If you really cannot identify the right type of gasket or if the door is not designed to receive a gasket (possible in very old houses), visit weatherstripping manufacturers’ web sites (for instance M-D) and look at your options. Prefer a screwed / nailed solution (more sturdy) than a glue on solution.

In my case, it was longer to remove the glue left by the inadequate weatherstripping than it was to install the new gasket. Here are a few views of the result:

 

The top corners are butted. The kerf on the jamb goes all the way up to the jamb while the kerf on the top stops 1/4 inch so I butted the gasket to follow this pattern (see right picture).

Sometimes, finding and installing the adequate gasket is not enough. In my case, the lock’s striker plate was installed too far away for the door to compress the gasket appropriately. The bad weatherstripping was interfering with the operation of the door and instead of fixing the real problem, the previous owner compensated for it by moving the striker plates. Once the plates were moved, the door closed fully and compressed the gasket adequately to form a tight seal.
