Customer Stories
Over 100+ verified reviews across Google and Yelp — averaging 4.9 out of 5 stars.
My home is very sound proof now. Cooler summer temperatures, holds heat much better in winter. The windows are way better quality than the big box competition — the appearance is a high end look. My overall experience was a 10.
Very helpful and accommodating. Respectful of our home while doing the job and willing to work on the price with us. We are very happy with the job and feeling warmer and quieter indoors now.
The crew removed and installed 14 windows and 3 sliding doors in about 7 hours. Everything looks and works great — we couldn't be happier. The price was the best of the 3 estimates we obtained.
Common Questions
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
