We are going to be replacing windows, doors and siding soon.
We have a lot of bugs that get into the hose particularly in the fall and
I was wondering if there is a house wrap that works better to keep some of these critters out and works as a water control.
The contractor also wants to replace the windows before they remove the siding. There is a different contractor doing doors and windows than the siding.
They said they would just cut the siding away from the window area and then install the new construction windows.
My concern is, can they properly seal everything if they go this route?
I normal have seen windows put in after the house wrap is applied.
Your input is appreciated.

Typically, it would make more sense for them to install the windows after the siding was removed, especially if they will be installing new house wrap before new siding goes up, but if they can't wait for that to happen then they can absolutely cut back the siding and get the windows prepped, flashed and sealed properly.
Your contractor doing the siding will just have to properly overlap the window area with new housewrap and tape the seams up.
Your contractor will install a peel and stick window flashing tape to keep any water from getting in, and that seals the gaps between the housewrap and the window on the exterior. They will probably use an insulation like spray foam on the interior side to fill up gaps around the window, and then use caulking to seal things off.
If they follow standard practices, there shouldn't be any bugs getting through unless your windows are open or have holes in your screens.

Hi Darwyn,
In retrofit situations, you have an opportunity to improve durability, comfort, and efficiency when replacing windows and siding. I'd recommend a self-adhering WRB. You'll get all the water control of a mechanically fastened WRB, plus a lot of air sealing. Here are a couple articles that might be helpful:
