Perfect Fit Guarantee Policy
If your window insert doesn’t fit perfectly, we’ll remake it – free of charge.
Even if the measuring mistake was yours.
Email us at info@martinsonmanufacturing.com and tell us what needs adjusting. “Make the width ½ inch shorter.” “Tighten the height.” Whatever it takes. We’ll cut a new one and ship it the next business day. We don’t leave customers stuck with something that doesn’t work.
