We were looking to replace our old sliding glass door with a new more energy efficient door. Alex had the best price and was quick to answer any and all questions we had. The door took about 4 weeks to come in but we were extremely happy with the finished product.

These guys replaced the majority of the windows in our home about 12 months ago. Their prices were the most competitive of all quotes we received and their installation process was seamless. We had to wait a while between ordering and installation, but it was worth it. Very pleased with the product and service. Great job, guys!

I'm so happy with my choice of hairing local company to exchange all my windows. Presented to me product was great, arrangements meet my expectations. My windows were fully exchange with the frame. The installers came on time, , did their Job and nicely clean after themselves. Windows look great with quality workmanship. Now 3 months later I can say that new windows block the street noice as well the Hause is warmer. We are giving them 5 stars because there is no more stars.

What are the best windows for homes?

Deciding the best windows for you home is not a simple task. There are many factors to consider such as the climate you live in, the window design, upgrades, and most importantly, your budget. If you’re looking for a low-maintenance type of product, slider windows are a good option. But if you want a more elevated look, bay and bow windows are a go-to. Remember that the less parts a window has, the less likely it is to break.

What should I look for when buying windows?

Aside from the usual—price, style, and features—, we think the most important thing when buying new windows is product rating. Customer reviews can provide helpful insight as to whether a brand or type of window is a good investment. So make sure you do your research and find windows with a high customer satisfaction rate.

What kind of windows are the most energy-efficient?

For the most part, low-E, argon-filled, double-paned windows provide significantly more insulation than a single-pane window. You can contact us directly to learn more.

What is the average cost to replace windows?

Window replacement costs most residents anywhere between $200 to $700 per window. Window installation costs in Toronto can depend on several factors such as the type of window, extent of labour, accessibility, and additional upgrades.

What is the best entry door?

A steel door is your best bet if security and durability are top priorities. Steel units are stronger than wood or fiberglass doors, and they won’t crack or warp.

What type of front door is most secure?

From front door security, avoid materials that can easily break or shrivel such as glass and wood. Instead opt for a door material that’s a little more durable such as steel or aluminum.

What type of door is most energy-efficient?

In general, fibreglass and steel doors are considered more energy-efficient than wooden doors. You can also add weatherstripping elements to doors to make sure they do not let air in or out of the house. This includes rubber seals that you can install in the gap where the hinges meet the door frame.

Which material is best for doors?

A mix of several materials is usually used in entry doors, but the three most popular choices for exterior doors are wood, steel and fiberglass. Which door material is best depends on your personal needs and budget. Wood is best for aesthetics, steel for security, and fiberglass for a low-maintenance alternative.

What should I look for when buying a front door?

Before you buy a new front door, you want to know that the company you choose stands behind its products and services. That way, if the front door you purchase is unexpectedly faulty or isn’t true to the product description, you can always make use of the warranty that comes with it.
