Hello, are there good references, such as books or websites, with overview of techniques for proper window waterproofing? There is an old kitchen window, without nail flanges, with rotten trim and with water damage underneath it. The window itself is vinyl and solid. The sides and the bottom of the window are quite drafty. What are the good ways to waterproof and insulate it? Would greatly appreciate any reference/suggestion. Thanks, h.

Youtube and Homedepot have many videos on projects for around the home. You might want to check there or any search engine should garner you plenty of responses.

Sounds like you have a vinyl replacement window.

Replace rotten wood trim. Seal were trim meets siding and window with chalking. Prime trim and paint with 2 coats of exterior trim paint.

To seal off drafts. Remove interior trim. Used spray foam insulation(Tough stuff) in the cavity between window and framing. This will expand to fill cavity and seal out draft. Let dry until next day. Clean off excess and replace trim.

You can use the same type of sealing tape they use on flanged windows. Just overlap on the window frame but you will need to pull the siding back. Bottom goes first, sides and then top. That way, water always flows across not under. You can replace the rotted brickmold (I assume it is brickmold) with composite PVC brickmold. From all your posts, you have your next year planned out and hope we have been helpful. Good Luck. Brian

Thanks. I have been thinking about overlapping too. Hope the tape adheres well to vinyl and there's no chemistry at the contact, where vinyl, sealant and the sticky tape meet.

No issue there, used all the time in new construction. HD and Lowe's carry it.
