Sliding Window Costs (Excluding Installation)
Low End Window
Low end sliders use vinyl frames with a simple low-e or clear glass package. Frame color will typically be a white or slightly off white. Entry level options will be a stripped down version of mid and high end windows. You can expect a simple plastic locking mechanism and the gliding rollers may not be as smooth as most better made series.
Price Range: $200 to $800 (excluding installation)

Mid Range Windows
Mid range sliders will often use a high quality vinyl extrusion or a mid grade aluminum or fiberglass frame. The glass package will be a mid range low-e option with simple fills and a spacer. These price point windows will include some bells and whistles such as a better locking mechanism, nicer hardware, more frame and grid option and perhaps a smoother glide.
Price Range: $800 to $1,200 (excluding installation)
High End Windows
High end sliders will be wood windows with an aluminum, fiberglass or vinyl exterior cladding and quality wood interior. The glass pakcage will be a high grade of low-e glass with premium fills and spacers. Expect bells and whistles here with high quality metal hardware and many frame colors, finishes and grid options.
Price Range: $1,200 to $1,700 (excluding installation)
Sliding Window Installation Costs
Installation window costs will range from $100 for pocket inserts to $450 for a full frame opening install. A professional installer should be able to quickly tell you what level of replacement installation you will need for your project.
Cost Range: $100 to $450
Entry Level Sliding Window Cost
Entry level projects run from $450 to $850 installed. Brands like Alliance, American Craftsman and Crestline would be in this range and homeowners can expect a window at this price point to last 10 to 15 years (this is one reason why the mid grade option is always recommended).
Price Range: $450 to $850
Mid Range Sliding Window Cost
Mid range projects run from $850 to $1,650 installed. Brands such as Anlin, Great Lakes and Okna Windows would be in this range and homeowners can expect a window at this price point to last 20 to 30 years with good quality installation.
Price Range: $850 to $1,650
High End Sliding Window Cost
High end projects run from $1,650 to $2,300 installed. Brands like Eagle, Marvin Windows and Kolbe would be in this range and homeowners can expect a window at this price point to last a lifetime with proper installation and care.

Window World Sliding Window Water Leak And Cost
| Window Type | Total Project Cost | Average Installed Cost |
|---|---|---|
| Window World Sliding Windows | Not Provided | Approximately $820 Per Window |
"We have Window World sliding windows and every time it rains, water ends up getting inside. I'm not sure where it's coming from, but I'm wondering if the drain holes on the sliders could be the culprit since our double-hung windows don't have the same issue. We paid about $820 per sliding window, so this has been really frustrating. One piece of interior trim came loose after getting wet, so I caulked around it, but now I'm worried I may have trapped the water inside instead of fixing the problem. I've also reached out to Window World Raleigh and haven't heard anything back."

Editor's Advice:
Annie, it's hard to say exactly where the leak is coming from without seeing the installation, but if I were in your position, I'd probably hire a reputable local window installer or repair company to inspect it. Paying someone for an hour of diagnostic work could save you a lot of time and frustration compared to waiting for Window World to respond.
Hopefully the issue turns out to be something relatively simple and inexpensive to correct. While they're there, ask them about proper maintenance for the slider tracks and weep holes since debris or poor drainage can sometimes contribute to water problems over time.
Even if it costs a little upfront, getting an experienced second opinion is often the quickest path to finding the source of the leak and avoiding more expensive water damage later on.
