The first question is why we’re called Great Windows. It’s quite simple really, we take the science out of buying windows and doors.

If we are installing a different type of window or door and additional construction work is required (for example, a sidelight for your replacement door or a build-out for a new bay window) then we will detail the cost of the window and the cost of the construction. Most homes use pvc replacement windows (otherwise known as vinyl replacement windows) but there are other options, you may read about it here.

The Science behind the windows – or rather, in them.
Obviously, there are certain things that you will want to know about all windows and we know, some of the terminologies can be a bit daunting. Read on to get a primer on some of the gobbledegook that you may well hear or read. We’ll do our best when you meet us to ensure that we don’t use any one of these terms more than once!
Low-E windows – Wikipedia refers to low-E as low emissivity or low thermal emissivity, a surface condition that emits low levels of radiant thermal (heat) energy. Or to put it another way, the windows let less heat from sunlight in. See what we mean, it doesn’t have to be difficult.
High-R windows – OK, let’s have fun, as Canada has gone metric we should refer to it as the RSI value, not the R-value. The R-value of a window is a measure of its thermal resistance, ie how good an insulator it is. Our windows are pretty much the same as any other mid to high-quality window. The secret is to install the replacement door or replacement window properly. Improper installation can potentially give you all kinds of leaks for heat to escape or enter when it’s not wanted.
Eco-friendly windows – Some of the most expensive replacement custom windows and doors available in the GTA are proclaimed as eco-friendly and have been manufactured in Europe. The carbon footprint of importation is massive unless of course the windows were put on a sailing ship! Some window manufacturers may use recycled vinyl, ours don’t. Windows are subject to massive temperature variations between summer and window, recycled vinyl is just not as hardy as virgin vinyl. Added to which, our windows are manufactured in the GTA.
So What Are the Key Things to Look for In Replacement windows and Doors?
A lot is made of the energy efficiency of replacement windows and yet this is a bigger question than it seems at first glance. It also opens a can of worms on the other things to consider when looking at window and door replacement.
So here’s a quick buying guide on what you should look at.
Vinyl replacement windows?
Or wood? Or….? Or….? In Southern Ontario, vinyl is generally the most sensible and cost-effective solution. Wood windows generally don’t hold up as well, for that reason we only offer high-end wood replacement windows and generally only as casement windows, that way we can be more certain of the quality and durability. Think about it, a more or less 60-degree shift in temperature is never good for any construction.
We also only use manufacturers that use virgin vinyl, not recycled. While we are very conscious of the environment, the reality is that doors and windows with a higher recycled content tend to be more brittle.
Energy Efficiency
Vinyl replacement windows are tested for their energy efficiency and assigned an R-value which measures their thermal resistance or insulating capacity. Most medium to high-end vinyl replacement windows has an Energy Star rating so it’s non-issue when you want to buy the actual replacement windows and doors. I’d love to say our vinyl replacement windows are better than the competitors’ doors and windows, they’re probably not, just the same in terms of energy efficiency.
So what is different?
Funny you should ask. Think about it, you’ve got your window and door replacement all lined up and the installation is shoddy. Shoddy installation results in air leaks around the replacement windows and doors and unfortunately, it’s really easy to tell after the fact by holding a naked flame close to the window edge to see if it flickers. Like I said, the trouble is that the window and door replacement has just finished.
Curb Appeal
Increasingly, doors and windows need to look spectacular from the curb. House prices in York Region continue to skyrocket and even if you’re not moving, you need to be in a place that looks like it’s worth the ridiculous amount of money that your neighbours are asking. Windows truly are picture frames to the outside but they also add a lot to curb appeal. Old windows look old because of the frames, vinyl replacement windows are typically white and really add a sharp look to the house.
Which reminds me. Think hard about whether you want brick to brick or frame to frame installation. Frame to frame is cheaper but the windows look smaller. I was driving by a house that had a frame to frame installation done in brown vinyl, the windows looked new….and awful. Big and brown frames.
The Sales Person
When we come round to your house to quote on your vinyl replacement windows, we act as consultants. We have the expertise in the wider home renovation that we make sure that we sell you the solution that fits your budget as well as your aesthetic. Replacement windows and doors need to complement the overall look of the house and quite honestly, our view is that if the doors and windows get in the way of the look, they should not have been installed.
We don’t need to make the sale. In fact, we turn down window and door replacement jobs. We don’t sell low-end windows and we won’t quote low to get a window and door replacement job. We’ll install doors and windows cost-effectively, we won’t do it cheap though
