This means that you can still expect a good quality window even though you are not buying a window with a higher grade.

Builder-grade/contractor-grade windows come in the form of many common types of windows like fixed windows, single or double-hung, slider and casement windows. Other qualities you may be able to find that affect the price of windows are features like Low-E film on the glass, which protects against UV rays.

What about Window Upgrades?

Many window installation and manufacturing companies offer additional features or add-on that enhance the window. These are nice to have but not necessary. Since these additional window features tend to drive up the cost, think about what you really need and leave out those you can do without. This will help you stay within your budget. Some of the add-ons include:

  • Between-glass shades – these windows have blinds integrated between the glass. These have become quite popular in the last decade because they do not collect dust as typical blinds do. This makes them a better fit for people suffering from allergies.
  • Laminate exterior glass – this glass is formed when heat and pressure are used to bond glass layers together using a resin called PVB (polyvinyl butyral). This makes the glass stronger.
  • Trim supplied – this is when the window company installs a window trim to cover the space between the window frame and the wall.
  • Company-supplied hardware – this typically includes items like coverings and other materials to install the window.
  • Integrated grilles (muntins and mullions) – this a metal or wooden strip used to hold glass panes of a window in place.

It’s now up to you to decide the window installation upgrades most essential to you and which ones you can do without.

Negotiate for Replacement Window Deals

What many people may not realize about window replacement companies is that they are willing to negotiate their prices. In fact, negotiation is expected and factored into the initial price. To beat off competition, many window replacement companies will give you great window replacements deals or even a price match to lock down your business.

This is because window companies buy windows at wholesale prices from a manufacturer. While you will have some wiggle room in your negotiations, remember each company will have a cutoff point where negotiations end.

Nonetheless, realizing you have the upper hand when it comes to negotiations can help you save more on your purchase.

Window Material Prices

Wood window frames are considered the highest-grade material for windows. It is classic and has been used for centuries. So window frames made from wood are expensive.

Fibreglass frames are a good alternative and cost less than wood. An even cheaper option than fibreglass is vinyl. Interestingly, it’s hard to tell the difference between these three types of materials. The most distinct difference is the price. When you think of it since it is very difficult to differentiate between wood and the other two types of materials, why pay more? If you want to reduce your window costs, you can do so quite easily by selecting a cheaper material.

Common Window Styles Save You Money

Sticking with regular or common styles of windows can save you big dollars. Some of the uncommon window shapes are curves, hexagons, circles, bays, and bows. The uniqueness of these windows will make them more expansive. You should also note that the more complex the window design is, the more challenging it will be to install. And that’s something you have to factor into your window installation costs.

Some of the more inexpensive window styles are casement windows, single- or double-hung, sliders and fixed windows.
