Question 1

What does a window warranty actually cover and what's usually excluded?

Accepted Answer

Window warranties can be confusing because manufacturers often make them sound comprehensive when they actually have significant limitations. Understanding what's covered before you buy can save you a lot of frustration down the road.

What's Typically Covered

Most quality window warranties include two separate components: a glass unit warranty and a frame/hardware warranty. The glass unit warranty (usually 10-20 years, sometimes "lifetime") covers seal failure — when the inert gas (argon or kr

Question 2

Is the installation warranty separate from the window warranty or the same thing?

Accepted Answer

Installation warranty and window warranty are typically separate coverages - the window manufacturer covers the product itself, while the installer provides warranty on the workmanship and installation.

Window Product Warranty covers defects in the window itself - things like seal failures in double-pane glass, hardware malfunctions, frame warping, or coating deterioration. These warranties typically run 10-20 years for quality windows and are provided directly by the manufacturer like Jeld-Wen

Question 3

What happens to my warranty if the window company goes bankrupt?

Accepted Answer

If your window company goes bankrupt, your warranty protection depends on the type of warranty and the company's structure. Most homeowners have some protection, but it varies significantly.

Manufacturer warranties typically remain valid even if the installing company goes out of business. Window manufacturers like Pella, Andersen, or Vinyl-Pro honor their product warranties regardless of who installed the windows. These warranties cover defects in materials and manufacturing, and you can usual

Question 4

If I sell my house can the new owner use my window warranty?

Accepted Answer

Most window warranties are not transferable to new homeowners, but this varies significantly by manufacturer and warranty type.

Manufacturer warranties typically fall into two categories. Product warranties that cover defects in materials and manufacturing are sometimes transferable, but often require specific steps like registering the transfer with the manufacturer within a certain timeframe. Installation warranties, however, are almost always tied to the original homeowner and contractor rel

Question 5

I heard using the wrong cleaner can void my warranty - is that actually true?

Accepted Answer

Yes, using harsh or abrasive cleaners can absolutely void your window warranty - this is a legitimate concern that many homeowners overlook until it's too late.

Most window manufacturers specifically exclude damage from improper cleaning products in their warranty terms. Ammonia-based cleaners, abrasive compounds, razor blades, and acidic solutions can permanently damage window glass coatings, vinyl frames, and weatherstripping. Low-E coatings on energy-efficient windows are particularly vulner

Question 6

The seal failed on one of my windows - how do I actually make a warranty claim?

Accepted Answer

Start by locating your original purchase documentation and warranty paperwork - this will have the manufacturer information and warranty terms you'll need for your claim.

Most window seal failures are covered under manufacturer warranties, typically ranging from 10-20 years for insulated glass units. The warranty usually covers the sealed glass unit replacement, though labor costs may or may not be included depending on your specific warranty terms. You'll need to identify the window manufactur

Question 7

Can the company refuse my warranty claim if I cleaned the windows the wrong way?

Accepted Answer

Most reputable window manufacturers won't void your warranty for using incorrect cleaning products, but they can refuse claims for damage directly caused by improper cleaning methods or harsh chemicals.

Window warranties typically cover manufacturing defects, seal failures, and hardware malfunctions - not damage from maintenance issues. However, if you use abrasive cleaners, razor blades, or harsh chemicals that damage the glass surface, Low-E coating, or frame finish, that damage won't be cove

Question 8

Does seal failure count as a manufacturer defect for warranty purposes?

Accepted Answer

Seal failure can count as a manufacturer defect for warranty purposes, but it depends on the specific warranty terms and the age of the windows. Most quality window manufacturers will cover seal failure under warranty if it occurs within the specified timeframe and meets their criteria.

Manufacturer warranties typically cover seal failure when it results in permanent fogging or condensation between glass panes that cannot be cleared. This is considered a defect in the insulated glass unit (IGU)
