What series Marvin? That being said, anything Marvin is a far better window than anything S/P or Harvey. Both are just a poor choice in my opinion.

Thank you! no idea what series of Marvin as I am not really familiar yet with these windows. any recommendations on this? Not sure why the builder loves SP but he said he even installed it on his own home. can it be they (SP) started to make better windows now? But yes, typically, people recommend Marvin as often never even heard of Harvey or S/P (hence my post here to see what the general public thinks). thank you!

" can it be they (SP) started to make better windows now? "

NO.

Thank you! that’s exactly what I needed - a reassurance. I’ll go with Marvin, then. but, which series????

Thank you. i will research it it’s just that I am not a technical type at all so this is pretty much Greek to me. will try to call them too to make sure I pick the best match for mountains. thank you all!

We had SP installed 7 years ago throughout our house, at the builders recommendation. The french doors leaked every single time it rained. SP eventually replaced them with windows, blaming it on the lack of overhang. Now, 7 years later we have had two windows fail on us - always during torrential rain, of course. The service team has been helpful but the product is mediocre.

Pretty much what @millworkman has always maintained.
