Dryer Piping Repair for Exterior Vents

Project Description

When we are doing dryer duct repair, we are looking for:

Correct and efficient airflow

  • To maintain proper airflow pressure, 4” ducting must be used on dryer systems.
  • Keeping ducting straight and airtight is essential to optimize airflow.
  • Dryer units should be installed as close to the exterior vent as possible; less ducting is better.
  • Loops, bends, and excess ducting drastically reduce airflow and create areas of lint buildup.
  • Keeping the dryer’s lint trap clean before or after each load is the best way to reduce lint buildup inside your dryer unit and ducting.

Exterior venting

  • Using the correct style of vent can make a huge difference in airflow and efficiency. We can provide and install the correct venting for all dryer systems.
  • Correct animal proofing (using the proper materials) will ensure the dryer vent stays clear of birds and rodents, while allowing proper airflow and reducing lint buildup on the exterior vent.
  • “Homemade” animal guards or other materials (such as wire mesh screens) can collect lint and create blockages if not installed correctly. They may also prevent airflow for the lint to pass through. This poses a serious fire hazard.
  • All our exterior vents and animal guards are made of heavy-duty, UV-resistant materials and are designed to last longer and perform better.
  • All exterior vents are properly sealed to ensure rain or insects can’t get between the vent and siding. Moisture can quickly create a huge, unseen mould issue and damage the structural integrity of the exterior wall. Insects (especially wasps) like to make their nests between the siding and interior wall of homes. Properly sealed exterior vents will help prevent these issues.

Piping conforms to all current fire codes

  • To meet current fire codes, plastic piping cannot be used on dryers.
  • All dryer piping must consist of heat resistant materials (e.g. non-flexible Galvanized Piping for electric dryers, non-flexible Aluminum Piping for gas dryers, or flexible aluminum piping for either).
  • Our flexible piping is constructed of heavy duty, fire resistant, aluminum foil laminate with a corrosion resistant wire helix. It will not support combustion.
  • We ensure all ducting is airtight.
  • All ducting is installed with no obstructions that may catch lint (screws, improper screening, other debris or blockages).

Dryer Piping Repair for Exterior Vents

Interior dryer unit cleaning

On an average dryer system, approximately 80% of dryer lint stays in the lint trap screen, 10% gets trapped inside the dryer unit, 5% stays in the ducting, and only 5% reaches the outside. It is important to have the dryer piping and dryer unit cleaned every 2-3 years. Excess lint buildup can be a serious fire hazard.

Cleaning the lint from the interior of a dryer unit can increase efficiency (drying clothes faster), improve air flow (less lint gets trapped in the ducting), and improve the life expectancy for the unit (preventing overheating and excess stress on interior components).

We clean out the dryer unit using high pressure, compressed air (250psi). We clean the dryer unit from the lint trap tray, pushing the lint out through the rear outlet and into our vacuum. We blow out the interior fan from the rear, as well as the interior/exterior venting. We vacuum any loose lint or debris dislodged during the cleaning from the drum (inside portion where the wet clothes go) and around the work area.
