Question 1

How long does installation take?

Accepted Answer

Most homes are completed in a single day. Larger projects (10+ windows) typically take 1–2 days. Our crew handles all prep, installation, and cleanup — you don't need to do anything.

Question 2

What does the limited double-lifetime warranty cover?

Accepted Answer

The warranty covers the glass seal against failure (fogging), the vinyl frame and sash against defects in materials or workmanship, and labor for any warranty repair visit. It is fully transferable to the next homeowner.

Question 3

Do you offer financing?

Accepted Answer

Ask your Tesla Windows sales representative about 0% financing for up to 18 months during your free in-home consultation. Financing approval and terms depend on your personal credit profile.

Question 4

How do I know which window type is right for my home?

Accepted Answer

Our in-home specialist will walk you through each option based on your opening sizes, ventilation needs, and budget. You can also compare styles using our online product guide.

Question 5

Can I get a quote without a home visit?

Accepted Answer

Yes — our 60-second online tool gives you a ballpark range instantly. For a binding price, we'll need to measure your openings in person at your free in-home appointment.

Question 6

Are your windows really ENERGY STAR certified?

Accepted Answer

Yes. We install energy-efficient windows that are independently tested and rated by the NFRC and designed to meet or exceed applicable Title 24 and ENERGY STAR® standards.

Question 7

Do you pull permits and handle HOA approval?

Accepted Answer

We handle permit applications in all jurisdictions where permits are required. For HOA approvals, we provide documentation packets and material samples to support your submission.

Question 8

What happens if a seal fails or glass breaks after installation?

Accepted Answer

A failed seal (fogging between panes) or accidental glass breakage is covered under warranty at no cost to you. We'll schedule a service visit, replace the affected unit, and handle the installation.

Question 9

What affects my final price — and how accurate is the online estimate?

Accepted Answer

Our online estimate is designed to give you a helpful ballpark range for your project. The final price depends on the number of windows or doors, each opening's exact measurements, your chosen product style, installation conditions, any structural work needed, and upgrades you select — such as sound-reduction glass, tempered glass, grids, frame colors, or premium hardware. Your free in-home measurement locks in the exact price.

Question 10

I've been meaning to replace my windows for years. When's the right time?

Accepted Answer

Every month you wait is another month of higher energy bills. At $420/yr average savings, a year of delay costs roughly $35/month. The second best time is now — the sooner you replace, the sooner the savings start.

Question 11

How do you compare to window programs from Home Depot or Lowe's?

Accepted Answer

Our customers frequently get estimates from both before choosing Tesla Windows. What they find: our pricing is comparable or lower, our double-pane products exceed what big-box programs offer as standard, and — unlike retail programs — we handle permits and HOA paperwork in-house. You work with one team from estimate to warranty claim.
