Capitol Door & Window

Capitol Door & Window is a Modesto-based window installation service and contractor that also operates as a hardware store, millwork shop, door supplier, and window supplier—making it a one-stop shop for new builds and replacements. Visit the showroom to compare door and window styles, hardware, and custom millwork options, and ask which products best match your climate, noise-reduction needs, and budget. Schedule an on-site measurement and estimate; confirm lead times, what’s included in installation (disposal of old units, interior/exterior trim, paint/stain), and whether permits are required. For a smooth project, bring rough opening sizes or photos, request an itemized written quote (products, labor, materials, warranties), and ask about energy-efficiency ratings, warranties, and any available financing or rebates.
