Experience Our Experience

The Window Nerd has been serving the southeastern Pennsylvania and central Jersey areas for more than three decades. Take a drive with our owner (whose been in the industry for more than 40 years), and it’s hard to find a neighborhood that doesn’t house at least one of his customers. Over our history, we’ve seen every window and door configuration and managed every construction hoop imaginable. We know what works, what doesn’t, and how to get the job done right the first time.

Options, Options, Options

While most other companies have their preferred window or door brand, The Window Nerd regularly sells and installs a variety of brands from 9 different top-rated window and door manufacturers. We have sourced the best brands of windows in every category to give you exactly what you want. By providing you with a variety of manufactures and materials, we can customize a solution that satisfies your individualized tastes, needs, preferences, and budget.

Craftsmanship At Its Finest

We employ mechanics that pay attention to the fine details. We don’t just slap a vinyl window into a hole as fast as we can. We work at an appropriate pace and with appropriate care. Our installers are capable of everything from the fine carpentry of wood window installations right down to the new construction vinyl window project. Whatever your needs, rest assured it’s going to look and be amazing.

10% Deposit. Bank On It.

For most installed projects, we collect a very small deposit. That’s right. You get to hold all the leverage. Think about that!!! We order custom products for your home. You pay almost nothing until we are finished. How likely do you think we are to provide outstanding service? You can trust us to do exactly what we say and do it really well.

No Sales Pressure. Period.

We are always a guest in your home, from the first meeting to the last bead of caulk on your new windows. As such, we always treat you with respect. Our sales appointments will never make you feel trapped or pressured into making a decision before you’re ready. We combine great products with great service. You’ll always get our low key approach with fair pricing right from the start. We let that do our selling for us.
