"We replaced the windows in our 1933 home through the services of MadCity Windows. From the initial contact with their sales representative to final installation, the company provided top notch professional work. With the draft from the old windows and the cold of the glass, we are already saving on our energy bills. Our house had old, large windows, so they had to be custom made. As an industrial designer and interior designer, we find our windows to be of excellent quality."

Glaziers FAQs, answered by experts

Installing glass block windows has benefits and disadvantages, as with most materials. The pros and cons can vary depending on the type of glass block and the window location.

Pros

  • Maintains privacy while letting light into the bathroom

  • Energy efficient

  • Sealed to prevent drafts

  • Aesthetically pleasing

  • Strong and secure

Cons

  • Costly to install

  • Challenging installation

  • Challenging repair

There is no blanket number when it comes to glass thickness for soundproofing. Thicker glass does help reduce noise, but it’s only part of the solution. Most single-pane windows use glass that’s ⅛” to ¼” thick. While increasing the thickness can cut down on sound, the real noise-blocking power comes from stacking layers. Double—and triple-pane windows are far more effective for soundproofing. The combination of mass and separation breaks up sound waves better than thick glass could on its own.

You should avoid multi-surface cleaners, bleach, and any cloth or scrubbing material that has a rough surface when cleaning mirrors. Multi-surface cleaners and bleach will get smudges and debris off of the glass, but they more often leave behind cleaner residue because they don’t evaporate like a glass cleaner or rubbing alcohol. Additionally, any abrasive material or even the scrubbing side of a sponge can scratch your glass or coatings on the glass, gradually making the mirror look hazy.

Standard mirrors come in many different shapes, sizes, and thicknesses, so you can often find a great fit for your space without adding customizations. Custom mirrors are ideal if your space has very specific constraints. For instance, you may need a much longer or wider mirror than you can find in a standard mirror. You might also want a custom mirror if you have particular styling preferences, such as a frame with a specific finish or a unique edge.

Yes, you can replace just the glass pane in a window without affecting the surrounding frame. This is a complex process, so it is best to hire a window repair professional to handle the task. A technician will cut the seal, remove the old glass, install the new pane, and properly seal it. For double-pane windows, this includes creating a vacuum between the panes and filling it with insulative gas to restore energy efficiency. Professionals can also help you choose the right type of glass for your window. This repair process is almost always more affordable than replacing the entire window unit.
