Customer Feedback
I was impressed with the professionalism and speed in which the men worked. The attention to detail was excellent. I needed extra vinyl trim for the door that hadn’t been properly completed by a siding company (years ago) and the Alpha Tech worker took measurements and will install this door surround trim for me. Otherwise it would be very difficult to get a small amount of finishing vinyl and someone to do that. Alpha gets a 5 out of 5 from me.

Replacing Your Windows? Here are some FAQs
How much does window replacement cost in Lethbridge?
Window replacement costs in Lethbridge can vary quite a bit depending on the style of window, the size, the materials used, and how complex the installation is. For example, a basic standard-sized window will cost less than a large custom bay window or a full-frame replacement. Energy-efficient and custom Canadian-made windows also tend to be higher upfront, but they often help reduce heating and cooling costs over time, which can balance out the investment. Most companies provide free quotes so homeowners can understand pricing before committing.
How do I know if I need new windows?
There are several common signs that your windows may need replacing. Drafts coming through closed windows, fog or condensation between glass panes, and difficulty opening or locking windows are all strong indicators. You might also notice higher energy bills or rooms that feel colder in winter and warmer in summer. Visible damage such as cracked frames, rotting wood, or warping are also clear signs it may be time for an upgrade.
How long does window replacement take?
The timeline depends on how many windows are being replaced and whether any structural changes are needed. In most cases, replacing windows in a typical home can be completed within one to three days. Larger projects or custom installations may take longer. Professional installers usually work efficiently to minimize disruption and ensure your home is protected throughout the process.
What are ENERGY STAR windows?
ENERGY STAR windows are certified to meet strict energy efficiency guidelines set for Canadian and North American climates. These windows are designed to reduce heat loss during cold winters and minimize heat gain during summer months. This helps improve comfort inside the home while lowering energy bills. They are a popular choice for homeowners looking to improve efficiency and reduce long-term costs.
Can I replace windows in the winter?
Yes, window replacement can be done in winter. Experienced installers use specific techniques to limit heat loss during the installation process, such as replacing one window at a time and sealing openings quickly. While summer is often seen as the most convenient season, winter installation is very common in Alberta and does not typically cause issues when done professionally.
What types of windows are available?
Homeowners can choose from a variety of window styles depending on their needs and design preferences. Common options include casement, sliding, awning, double-hung, bay, and bow windows. Each type offers different benefits in terms of airflow, natural light, and ease of use. Many companies also offer custom sizes and designs to match the look of your home.
Do new windows increase home value?
Yes, new windows can add value to a home. They improve curb appeal, enhance energy efficiency, and reduce maintenance concerns for potential buyers. Updated windows are often seen as a major selling feature because they improve both comfort and long-term cost savings. While the exact return varies, window replacement is generally considered a strong home improvement investment.
How long do new windows last?
High-quality windows can last anywhere from 20 to 40 years or more, depending on the material and how well they are maintained. Vinyl windows tend to have long lifespans and require very little upkeep. Proper installation also plays a major role in longevity, as well-installed windows are less likely to develop issues over time.
Are vinyl windows a good choice?
Vinyl windows are one of the most popular options for homeowners in Alberta because they are affordable, durable, and energy efficient. They perform well in cold climates, require very little maintenance, and do not need painting or staining. Modern vinyl windows also come in a wide range of styles and finishes, making them a versatile choice for many homes.
Do I need to replace all my windows at once?
No, you don’t have to replace all your windows at the same time. Many homeowners choose to replace windows in stages based on budget or priority areas of the home. Others opt for a full replacement to ensure consistency in appearance and performance. A professional assessment can help you decide the best approach for your situation.
