Installing new carpet is a major investment. But even the best carpet can fail if it’s installed incorrectly.
Before hiring a carpet installer, ask these six important questions to protect your home, your warranty, and your wallet.
1. Do You Follow CRI 105 Carpet Installation Standards?
The Carpet & Rug Institute (CRI) sets the industry standard for residential carpet installation under CRI 105 (CRI 104 applies to commercial installations).
Why this matters:
-
Many manufacturers require installation to meet CRI 105 standards
-
Improper installation can void your carpet warranty
-
Following standards ensures long-term durability
Ask your installer directly:
“Do you install according to CRI 105 standards?”
If they hesitate, that’s a red flag.
2. Do You Use a Power Stretcher (Wall-to-Wall Stretcher)?
Proper carpet installation requires a power stretcher — not just a knee kicker.
Without a power stretcher, carpet can develop:
-
Wrinkles
-
Ripples
-
Buckling
-
Premature wear
Most manufacturer warranties require proper stretching. Always confirm the installer uses professional-grade equipment.
3. Are You Using the Proper Tack Strip?
Quality installation includes the correct materials.
✔ Standard 1” or 2” wide tack strip provides a secure, lasting stretch
✘ ¾” tack strip is cheaper and not industry standard
Also important:
Tack strip should not be used in doorways where carpet meets tile, hardwood, or vinyl. Proper metal transitions or rolled edges should be installed instead.
4. Do You Reinforce Stair Noses?
Stairs receive the highest wear in any home.
A skilled installer may apply reinforcement (such as properly placed duct tape over padding at stair noses) to:
-
Reduce wear
-
Protect padding
-
Extend carpet life
Details like this separate experienced installers from budget installers.
5. What Installation Warranty Do You Provide?
Manufacturer warranties cover factory defects — not poor workmanship.
Ask:
-
How long do you warranty your installation?
-
Is stretch warranty included?
A properly installed carpet should last well beyond one year without stretching issues. A reputable installer should stand behind their work.
6. Do You Use Seam Sealer on All Seams?
Seam sealer is required by most carpet manufacturers.
Without it:
-
Seams can separate
-
Face fibers can unravel
-
“No-Run” warranties may be voided
Every seam should be sealed. No shortcuts.
Bonus Questions to Protect Your Investment
Before scheduling installation, also ask:
-
Are you licensed and insured?
-
How many years of installation experience do you have?
-
Can you provide references?
-
Who moves furniture?
-
How long will installation take?
Why Proper Carpet Installation Matters
Poor installation can lead to:
-
Wrinkling within months
-
Visible seam failure
-
Premature wear
-
Voided manufacturer warranty
-
Costly reinstallation
Professional installation ensures your carpet performs the way it was designed to.
