Vinyl Windows: Frequently Asked Questions

Does ALDA manufacture its own windows?

No. ALDA Windows and Doors is a factory-direct retailer and installer, not a manufacturer. We source ENERGY STAR-certified vinyl windows from trusted manufacturers and cut out the middleman, so you get manufacturer pricing with local, hands-on installation and support.

How long does a window installation take?

Most window installations take about 5 to 6 hours per visit, depending on the number of windows and any custom sizing. Our team schedules the full job with you in advance so you know what to expect on installation day.

How soon can I get my new windows after ordering?

It depends on the style you choose. Some standard sizes are in stock and can be delivered in about 1 to 2 weeks. Custom sizes, colours, or grille patterns can take a few weeks longer. We will give you a firm timeline once you have picked your options.

Do vinyl windows qualify for rebates in Ontario?

ENERGY STAR-certified windows like ours can qualify for Ontario’s Home Renovation Savings Program (Enbridge Gas and Save on Energy), which offers $100 per window or door replacement when bundled with another qualifying upgrade, through November 30, 2026. Note that the separate federal Canada Greener Homes Grant closed to new applicants in 2024. Ask us for the current details when you book your free estimate.

What warranty comes with ALDA vinyl windows?

Warranty length depends on the window line and options you select. Some of our vinyl windows carry a lifetime warranty, while others carry a 25-year warranty, depending on the manufacturer you choose. We will walk you through the exact warranty terms for your selection before you order.

Do you offer black vinyl windows?

Yes. Black vinyl frames are one of our most requested finishes, and they hold up well thanks to modern heat-resistant vinyl formulations. Ask us about black vinyl windows when you get your estimate.

When it comes to choosing your window glass, you have two options. You can choose between low-e coating or argon gas.Low-e coating glass has been designed to minimize the amount of infrared and ultraviolet light that comes through the glass, without minimizing the amount of visible light that enters your home. Argon gas glass reduces heat loss in sealed units. This is done by having double-pane windows filled with argon gas to help insulate the room and minimize the transfer of heat through the window glass.

 Trustindex verifies that the original source of the review is Google. Absolutely phenomenal experience with Alda Windows and Doors!

I honestly couldn’t be happier with my experience from the moment they arrived, the very first consultation through to the final installation, everything was handled with professionalism, care, and real attention to detail.

The new door installation in my home is absolutely flawless. The craftsmanship is exceptional—you can truly see the quality in every detail, and it has completely elevated the look and feel of my home. It feels solid, secure, and beautifully finished, exactly what I was hoping for.

The installation team was respectful of my home, punctual, efficient, and left everything spotless when they were done. I also have to mention the pricing was very fair and excellent value for the level of quality and service provided.

As a homeowner, it’s rare to feel this confident in recommending a company, but Alda Windows and Doors truly exceeded my expectations in every way. I wouldn’t hesitate to use them again or recommend them to anyone looking for top-quality workmanship.

Thank you Leon,
Nelia, Bradford ON

 Trustindex verifies that the original source of the review is Google. I've hired ALDA twice now to replace windows and doors in my homes. Each time I've tendered multiple quotes and each time ALDA has bested all other companies. Next time, I'm going to skip the other quotes and just call ALDA, they've earned my trust and business. I was kept in the loop at all points and they also followed up after their installation to make sure I hadn't noticed any issues. Their estimators and installers have been extremely attentive and I was never "up-sold" at any point during the process which I appreciated. Get them to quote your job if you're skeptical but I haven't found another installer that comes close.

 Trustindex verifies that the original source of the review is Google. Alda Windows and Doors provided an excellent experience from start to finish. They installed a new front door, garage to yard access door, and a house-to-garage door which was recently added to the house design. All work was completed professionally with clean, finished trim. The team was punctual and maintained constant communication throughout the process. The workmanship and organization really stood out! Highly recommended!
