Comprehensive Fit


In some cases, there’s no need to replace the box frame. In these cases, our sash replacement service could be useful to you. Essentially we’ll try to save you some money and just restore your current frame while we replace just the sliding sashes. This will leave you with brand new sashes with very similar heat retention / noise exclusion as a brand new box might have.
