Welcome to gowindowgo.com and Diamond Wholesale LLC., We are the authorized distributor for Semco out-of-warranty replacement parts. If you are looking for replacement parts or upgrades to enhance your current Semco products, you can purchase them below using our e-Commerce site, which has over 7,000 Semco items. 

Please read all the product descriptions carefully, as items are considered special order and are non-returnable. If you cannot find the part you are searching for below, please contact us. Note that all parts take between 15-30 working days to ship. Each parts description online will show lead-time for that particular product.

A Note to our Existing Customers

We have recently changed website platforms. What this means, is that existing customers will have to create a new account if you have not been to our site since January, 2014. We appologize for this inconvenience, but with our new upgrade we're hope to make your experience easier, more streamlined, and secure.
