Our Customized Window Replacement & Installation Comes With These Benefits

Elite Craftsmanship

We employ the highest quality control standards and the latest engineering techniques to be able to give you precisely what you need. Customized window replacements and installations allow you to improve the practicality of your space. The precision involved means you can get a perfect fit which doesn’t only look good, but works perfectly as well.

Demers Glass is bold enough to give you the freedom of customization. It takes a lot of courage to tell your customer they can imagine anything and you can make it real; just as they imagined. Not many window and glass companies can do this for you; most of them will just push a standard window arrangement on you.

This should tell you that customized window installation is not a joke; only the best glaziers can pull it off. If one measurement is off, the whole project is jeopardized. The fact that we’re flexible when it comes to design shows that we’re good at what we do.

It can be quite challenging working with a customer who has very specific needs. That’s why most companies would rather just give you a bunch of templates they’re comfortable working with. There isn’t a single job that is too complicated or outside of our expertise. We don’t just have normal handymen on our team, our people are known to be some of the best window and glass professionals in Arizona.

Meticulous Design

We know that you want your windows to compliment the surrounding design elements in your space. You’re free to guide us in terms of measurements and dimensions and dictate what style you want for your windows.

You can expect to get exactly what you ordered, down to the last inch and decimal point. We take our time with design builds, taking all your instructions into consideration to make sure you’re 100 percent satisfied. We know how important both aesthetics and practicality are, so we carefully use our time-tested methods to make sure the form and function of your windows achieve what you want them to.

Say you spend a lot of money cooling or heating your space. With the right window design, you can keep that space cooler when it needs to be cooler and warmer when it needs to be warmer.

Installing ordinary windows is hard enough, custom windows call for an even greater attention to detail. The accuracy required for custom windows means that the smallest details are given special attention. Sometimes, it’s the little things the count, our personalized window services allow you to make those tiny tweaks that enhance your home’s aesthetic.

Superior Quality

The great thing about going with customized windows is the fact that you get to decide what materials your windows are made from. Not all materials are equally durable, so if you want something that lasts, you can have your pick at the more sturdy stuff. If you want something with wood, we won’t just shove any species in your face. You can weigh the pros and cons of each variety to get the kind that would serve you best.

We’ve partnered with various companies in a collaborative effort that results in a level of quality that you won’t find anywhere else. It’s just like they say; “two heads are better than one”.

The quality of a window is largely determined by what it’s made of, how it fits into its surroundings, and what ‘feel’ or ‘look’ it gives off. As someone who knows their own space best, consulting with you; the customer, allows us to provide you with the highest grade of service there can be.

You hardly think of comfort when you think of windows, but light directly affects our mood, and the way in which your windows reflect light can mean the difference between a relaxed atmosphere or a tense one.

Your windows won’t be the most prominent feature in your space, but they definitely will add to the ambiance of the building. Also, because you can choose the color, shape, and placement of your windows, there’s a lot of room for creativity.

Frequently Asked Questions:

Q: How Much Does It Cost To Replace Windows?

A: It all depends on the size, materials, and features. Due to the number of variables that determine pricing, we encourage you to take advantage of our free consultative approach by giving us a call to get a custom quote.

Q: How Do You Measure For Replacement Windows?

A: We’ll have a technician remove the functional features and glass parts of your old windows, taking care to measure the spaces where your replacements will go. Most projects we come across don’t even require our expert to get inside; all the measurements can be done from the exterior.

Q: Window Repair Versus Replacement?

A: Depending on whether or not your window is damaged, and the extent of that damage; you might have to replace your windows completely. If the moving parts or the frame is damaged somehow, replacement is the way to go. If they refuse to open or close smoothly, you still might want to consider a replacement. Repairing a window can be more expensive than replacing one, so consider why you want new windows.
