I'm considering using built-in J channels for my new double hung windows, but I'm curious if there are any drawbacks. Are there any negatives I should be aware of when choosing this option?

Generally, new construction vinyl windows don't require a traditional drip flashing if they have built-in channels. However, you should definitely apply weather seal tape to prevent air leaks. It's all about making sure everything is sealed up tight!
Aesthetically, built-in J channels usually look better! They give a sleek finish compared to the traditional option. Just keep in mind that this option might not be as practical for every situation, depending on your siding and weather conditions.
