- For Small Openings: Use duct tape or foil tape to cover the opening from the dryer side. - For Larger Openings: Cut a piece of sheet metal or plywood to fit over the opening. Secure it in place with screws or heavy-duty adhesive. - Optional: For extra insulation, you can caulk around the edges to prevent air leaks.
Using duct tape on a dryer vent is not recommended. While it may seem like a quick fix, duct tape can degrade over time due to heat and moisture, leading to potential leaks and reduced efficiency.
You could open yourself up to a pest infestation if your dryer vent isn't sealed properly. On top of that, cold air from outside will more easily mix with hot air in the vent, which can promote condensation and water leaking from your dryer vent.
Loctite Extreme Glue is a super versatile adhesive that is perfect for sealing dryer vent pipe leaks. The high-viscosity and permanent flexibility make it resistant to vibration, moisture, heat, and UV light.
A: The tape is flammable and burns very well so I would not recommend it. If the hose needs to be replaced I would just replace it, if you're trying to keep the connection tight they make hose clamps that are sold in the same section as the hoses to do that repair.
Foil duct is held in place with dryer clamps or large hose clamps. Metal tape can also be used to secure the flexible aluminum duct, too, but clamps make it easier to remove the tubing for cleaning.
A: YES, it is an excellent waterproof sealant. Flex Paste can be used on windows, doors, vents, thresholds and so much more.
Lint and other fabric particles can build up over time, and eventually they block the flow of air through the pipe. When the hot air becomes trapped, it can condense into a liquid buildup that leaks through the pipe. In these cases, a dryer vent cleaning may be enough to solve the problem.
If it's permanent, just remove the pipe and patch the wall/siding using appropriate materials. If it's temporary, you can buy a little bundle of fiberglass insulation. I'd stuff that into the pipe and then use some UL181 tape to tape up the end and/or tape closed the louvers.
Seal the exhaust duct to the fan box with approved metal tape or mastic. Seal around the exterior fan duct vent with caulk or a pre-made exterior wall gasket. If duct vents through the roof, install flashing around the vent that is properly integrated with roof paper and roofing material.
Use External Vent Covers: Install an external vent cover that prevents pests, debris, and inclement weather from entering the duct while allowing proper airflow. Never install screening or a filter at the end of the dryer vent. It is recommended that a Type “B” exterior wall cap be used.
If the hose is torn or crushed, you will need to replace it. If you are repairing a foil-type vent hose, you can use aluminum tape to patch the hole.
If your dryer vent is blocked, all of this built-up lint can become a fire hazard. The heat from your dryer could cause the lint to combust, potentially catching your dryer and parts of your home on fire.
We do not recommend using Flex Seal on foam. Some foams may react poorly with Flex Seal, and may warp or dissolve. We also do not recommend using it in situations where it is subjected to high heat or pressure (such as engine radiators) or gas tanks. We do not recommend the use of Flex Seal spray on vinyl.
Flexible transition hose between the dryer and the wall outlet should be either the foil type or the aluminum flexible duct (most preferred). Do not use the plastic or vinyl. Concealed ducting must be rigid metal (galvanized or aluminum) duct.
Do not use duct tape to seal a hole in your dryer vent or connect it to the wall or for any other reason. Duct tape should also not be used on your air ducts. Duct tape is a common household item but poses a serious threat to the safety and health of your home when used on dryer vents.

The maximum length of the exhaust duct does not include the transition duct. This means that vents should also be as straight as possible and cannot be longer than 35 feet. Any 90-degree turns in the vent reduce this 35-foot number by 5 feet, since these turns restrict airflow.
The flexible nature and expandable configuration allow most installs to occur without any modification to the duct or the wall penetration. A pair of jumbo zip ties and you're good to go…at least for a few months until all of the internal bumps and ridges begin to clog with lint.
Foil tape is known for its excellent insulation properties. Since it is made of aluminum, it prevents heat or cold air from escaping a system, which makes it an excellent accessory for both duct cleaning and dryer vent cleaning.
You'll want to decide between vent clamps or foil tape to secure the dryer venting to the dryer exhaust outlet and wall vent. If you're using a vent clamp to secure venting, place the vent clamp loosely on the edge of the vent hose and slide the edge of the vent hose over the wall outlet.
