Question 1

What condition must be met before installing carpet over a radiant-heated floor system?

Accepted Answer

The system should be operating at normal temperature for at least 72 hours, then cooled before installation

Radiant heat floors should operate at normal temperature for 72 hours to normalize moisture content in the substrate, then be cooled to room temperature before carpet installation.

Question 2

When installing carpet in a doorway between two rooms, how should the seam be positioned relative to the door?

Accepted Answer

At the outside edge of the door stop on the pull side

Answer

The seam should be placed at the outer edge of the door stop on the pull side so it is protected by the door when closed and hidden from normal view.

Question 3

What is the purpose of 'cross-seaming' in a large carpet installation?

Accepted Answer

Joining carpet widths with seams that run perpendicular to the main seam direction to reduce waste

Answer

Cross-seaming runs seams in a perpendicular direction to utilize off-cuts and reduce material waste in large installations.

Question 4

How far should the nails or pins on tackless strips point toward the wall?

Accepted Answer

Angled at 60 degrees toward the wall

Answer

Tackless strip pins are angled at approximately 60 degrees toward the wall so they grip the carpet backing and hold it in tension toward the wall.

Question 5

When a customer wants to install carpet over existing hardwood floors, what is the PRIMARY concern the installer must address?

Accepted Answer

Height change at transitions and any loose or squeaky boards that must be secured

Answer

Loose or squeaky boards must be secured before installation to prevent noise and movement under carpet, and transition heights must be evaluated to ensure door clearance.
