When it comes to Bi-Folding Closet Doors, the truth is simple: this is NOT a DIY-friendly project. These doors require precision, specialty knowledge, and the right techniques to get them installed correctly — and that’s exactly why homeowners trust Classic Improvement Products.

Below is the real breakdown of why professional measurement and installation matter (and why big-box “one size fits all” options fall short every single time):

1) Big-Box Stores Sell “One Size Fits All” — And It Shows

Sure, you can always get something cheaper at a big-box store. But those doors are generic, mass-produced, and depend on you forcing them to fit your opening.
The result?

• Gaps

• Uneven reveals

• Crooked operation

• Panels that rub, bind, or never close properly

Trust us — you’ll notice, and so will everyone else.

2) Measurements Are EVERYTHING

Bi-folding doors require millimeter-level accuracy. With over 22 years of experience, we know exactly how to measure each opening so the doors function flawlessly.
One wrong measurement… and the whole system fails.

3) Closet Openings Must Be Perfectly Square — And They Almost Never Are

This is where 90% of DIY installs go wrong.

To properly install Bi-Folding Closet Doors, the opening must be:

• Squared left to right

• Squared top to bottom

• Equal width at the top, middle, and bottom

• Equal height on the left, center, and right

• Not cantered or leaning

We install custom jambs on the left, right, and top of the opening to create a perfectly square frame — because most home builders did not.

This step alone is one of the biggest reasons professional installation costs more…
We do it right. We don’t cut corners.

4) We Protect Your Home (And Your Stuff)

Before installation, we cover the inside of your closet with plastic to protect clothing, shelves, and personal items from dust or damage.
It’s all part of our professional process.

5) The Doors Themselves Are Custom Ordered

Bi-Folding Doors are NOT universal. The panels must be ordered with the correct factory deductions based on the product type:

• Hollow Core

• Solid Core

• Aluminum Frame

• Custom Designs

Each style requires different margins, clearances, and balancing — and we handle all of it.

6) Your Time Is Valuable — Let the Pros Handle It

A homeowner attempting this job will often spend an entire weekend, sometimes two, trying to:

• Square the opening

• Install jambs

• Drill hardware

• Adjust pivots

• Re-adjust pivots

• Fix rubbing panels

• Re-fix rubbing panels

• Try to get the doors to operate correctly

Our experts?
Two hours or less per opening — done right the first time.

Enjoy your life. Spend time with your family. Leave this one to the professionals.
