      Cindy, If these are casement windows, we probably have the profile you need. You are welcome to complete a quote request on our website with all of the required information and we’d be glad to help.

    My home was built in 1992, and includes three casement windows that I believe were manufactured by Biltbest. These are aluminum clad wood, and one of the sill members of the operable portion has considerable rot. I would like to replace either the sill member, or preferably the entire operable portion, leaving in place the existing frame. The rough opening of the window is approximately 29″ wide x 46″ high, and operates outwardly with the hinge on the left, as viewed from the outside. Can you help? If so, what information do you need to provide pricing?

    Thanks for your attention.

      Kent, Unfortunately we do not have any frame components for clad windows.

    I am looking for BiltBest latching mechanisms to repair windows in my parent’s home. The parts are stamped “BILTBEST STE.GE> L62”

    I am looking for 2 of these in gold. Can you help?

      Barb, I am familiar with the type of lock you need, but I don’t know exactly which one Biltbest used on which models. All I can offer is our distributor’s catalog link on our website under the special order hardware product tab.

      Darrell, Unfortunately those numbers don’t mean much to us. The hardware side of things is not our specialty. We would be happy to research it for you if you could send us one to look at, or send us some pictures of what you need to sales@fensterusa.com

    Hi, we have Biltbest double hung and casement that are “milky”. Can just the glass be replaced and can Fenster do that work?

    • Posted July 4, 2016 at 1:45 pm | Permalink

      Robin, The models of Biltbest I am familiar with have direct set glazing. Meaning, the glass is glazed directly into the sash without a boot seal or stop. So, it is very difficult to remove the glass without destroying the wood frame. We are a manufacturer so we don’t have field techs to perform the work. However, we can make you new window sash assuming we have the profiles that match you existing model of window. You can view those profiles on our website at, http://www.fensterusa.com.

      Scott, Thank you for all the information. Unfortunately, its not the info we need. It sounds like you just need jambliner kits? I can’t say for certain what type of jambliner your model of window used. You can order jambliners from our website at http://www.fensterusa.com. Thank you.

      Scott, I’m assuming you mean the weatherstripping? I couldn’t tell you without seeing it. We don’t do a lot with Biltbest. You might try their site and see what they offer.

    My windows were installed in 2007 and are a dark brown/black color but The edges have lost their color. Is it possible to have my painter paint these? If so, what kind of paint do you recommend?

    • Posted May 21, 2020 at 6:45 pm | Permalink

      Sure that’s easy. Any exterior paint made for metal or aluminum siding will work great!

    Hi Ryan, I hope to order some double hung sash replacements for BiltRight aluminum clad windows. (1994) I noticed that they seem to fail the same way. The bottom meeting rail of the top sash has some water damage in all the windows that have failed or are starting to. The meeting rail starts to separate from the sash, taking the cladding and double pane with it. Can the failure be repaired when the separation is just starting? Or do we just need to bite the bullet and replace the sashes that are starting the process since we are making an order now?

    • Posted July 29, 2020 at 11:53 am | Permalink

      Brian, I feel your pain. That is a very common problem with double hung windows. The wood core beneath the cladding is most likely rotted out. There’s no really good way to repair that. Replacing the sash is probably your best options. However, it pains me to say, we currently are not able to produce our double hung kits. We’ve had major disruptions to our supply chain and I can’t even get anyone to talk to me about a new relationship. Vinyl extrusion companies don’t seem to be looking for new business right now. Something must be going on in that industry that I’m not hearing about. Long story short, I don’t have much I can offer you at this time.

        Oh, wow! That’s not good news! I should have jumped on this in February when the tape was still holding the top sash together! We lost that top sash completely the other day, I figured we’d get by with some Plexiglas and Styrofoam until we could get replacements made. No ideas about custom replacements anywhere eh? Of course the thermopain is fine. The head and stiles are in good shape, the tongues that would connect into the meeting rails have some rot, but maybe I could find someone to build a new meeting rail for the top sash to rebuild and glaze our existing window? We’re not far away, btw!

        Normally BiltRight replacements would be aluminum clad wood right, if you were able to get the parts? I was a little confused about mentioning vinyl extrusion.

        Brian, That’s probably your best bet. Have a carpenter with a small shop make you the pieces you need.

    We purchased a home with Biltbest windows. Some of the windows need new crank mechanisms. There is a part number 233 D. C. molded into the crank mechanism. The arm attached to the window is fine but some of the crank mechanisms are seized or just spin freely without engaging the gear teeth on the arm. It looks like the crank mechanism has a worm gear that engages the straight cut teeth on the arm. Can you help with these parts? I think the house was built in the 70’s.

      Scott, We’re not really on the hardware side of things. There are several window hardware companies like Blaine’s or Swisco that could probably help you.
