How to Hook Up a Dryer Vent in a Tight Space: Apply 10 Effective Methods


According to a National Fire Protection Association study, 92% of all home fires in structures involve dryers. This number could be highly alarming if you try to put in vents for dryers within a restricted space. This guide will assist you in staying clear of fire hazards. If you are hooking up the dryer vent to the smallest room, selecting periscope or slip vent ducts are best. Periscope vents can be adjusted enough to accommodate tiny spaces. Install the slim venting to the wall first, then move the dryer in the proper position following a snug-fitting. Fill in any gaps using foil tape. In the next section, we will discuss how to hook up a dryer vent in a tight space. We will also discuss the other potential issues you must watch in these situations.

How to hook up a dryer vent in a tight space

Are you looking to find out how to connect the dryer vent to a tight area? You’re at the right place. Installing a dryer vent can be complicated even if you follow everything correctly. However, with the proper steps (and tools), you can get it completed safely and smoothly. You must learn a lot of things before you’re going to hook up a dryer vent in a tight space. The process of connecting dryer vents to the wall is an intimidating task. However, with the right tools and equipment, it is much simpler.

Offset dryer vents

One of the most crucial things you need to be aware of is that you might need the offset vent. The vent is flat and slim, allowing you to push the dryer towards the wall. It is vital to check with the manufacturer how long the periscope vent can be removed. Specific vents with offsets can only be adjusted a few inches, whereas other periscope vents may be removed for a one-foot or even more.

Dryer vent cleaning

Offset dryer vents must be cleaned at least once per year. If the vent for your dryer gets blocked, it may limit the flow of air. The reduced airflow results from the lint accumulating and could cause a fire. Unfortunately, these vents with flat sides are rectangular, making them more vulnerable to accumulating lint particles. It is possible to clean the vent every 3 to 6 months so that it doesn’t hinder airflow.

If your dryer takes a long time or becomes very hot, you might require cleaning the vents for the periscope. Also, you can examine the hood’s exterior outside to check the airflow is less while the dryer is running. Do not forget that you’ll also have to clean the whole wall duct once per year, not just the dryer vent offset. It is recommended to have the dryer duct regularly by an expert is highly advised.

Pull out the dryer and unplug it

Remove the dryer as far as you can, and then unplug it. If your dryer is placed in a cramped space, one option is to climb up over the dryer to reach behind it. It may be necessary to use an inclined ladder to get into the space behind your dryer. It is hoped that you will be able to pull out the dryer enough to reach it without climbing over it.

Loosen the old clamps holding the old vent

Remove the old vent and wall collar away from the dryer behind it. There’s likely to be a clamp made of metal at each end of the vent for your old dryer. You will have to remove the screw holding them in the position. To simplify this process, dryers close to the wall prefer to use an extended versatile drill since it lets you access those difficult areas behind the dryer. Flexible drill bits can span as long as 8 inches, and the drill bits are adjustable up to 300 degrees in a variety of directions so that you can get to your clamp screws. Don’t forget that you can reuse the clamps made of metal used on your new vent.

Remove any tape securing the vent

Take off any vent tape made of metal (or duct tape) that holds the vent to the wall. To do that, employ a knife and cut the tape. After cutting the video, you can pry it and take it off. Make use of a tape measure to measure the distance between an air vent in the wall up to the centre of the dryer’s collar.

Adjust the length and direction of the offset vent

You can adjust the size of your periscope vent so that it will align with the distance you measured between the vent on the wall and the rear to the back of the dryer. For most offset vents, you can pull it out and extend it. Periscope vents can be pulled as long as 5 inches or greater. Also, turn the offset vent around to align with the direction of the vent on the wall. The vent in the wall may be situated above the dryer’s duct collar or could be located to one side.

Connect the end of offset vent to the back of the dryer

Connect the more oversized neck of the vent to the rear of the dryer’s pipe. The larger vent of the offset vent was made to be able to sit onto the dryer’s vent. After fitting, you must fix it using one of the clamps made of metal which you had removed earlier. It’s also a good idea to place vent tape of metal on the clamp to create more security. Vent tape made of metal is different from regular duct tape, specifically designed to stand up to extreme temperatures.

Align the offset vent with a wall duct

Make sure that the offset vent is aligned to the wall duct by twisting the vent until it is in line with the exact location. Periscope vents can rotate around an axis. You must align them with the wall duct so that when you press back the dryer, it will be able to fit.

Connect offset vent to wall duct

The dryer should be moved back towards the wall. If the dryer is near the wall, check in the back of the dryer and confirm that the offset vent is lined against the wall. You might need to go toward the dryer (or employ the stick) to ensure that the offset vent is connected to the wall vent. Its duct collar, inserted into the wall duct, will be shorter and crimped to fit inside the wall-mounted chimney.

Secure the wall duct with clamp and metal tape

Connect an insulated wall to the vent offset with a clamp’s help. There should be an old clamp that you took out before this, and then fix it using a power screwdriver or drill. Installing a vent tape of metal over the clamp can help prevent the offset duct from falling away. But, in a tiny space, there could not be space behind the dryer to place the clamp or tape, and the video will need to be fixed by the pressure of the dryer.


It’s a difficult job, but with appropriate tools, and by taking the steps step-by-step, fitting a dryer vent into a tight area can be done. Some essential tools include a small, cordless drill, vent clamps made of metal, flexible extension drill bit holders, metal foil tape, and a flat air vent (called”offset vent”). Don’t forget to inspect the vent hood’s airflow to ensure that the airflow is stable. If the airflow becomes weak, it may be necessary to clear the offset dryer vents of the lint. Additionally, ensure that the vent flap outside is operating correctly by opening when there’s airflow and closing when the dryer is stopped.
