California Window & Exteriors, Inc., is your best choice for all of your home improvement needs. My name is Jeffery Petty and I am the owner of the company. I have been in business for over 15 years while carrying my same installer since 1998. Please look at my reviews as I have over 150 with a very high rating which shows longevity and quality.

"I am generally a DIY'r and a while back I purchased six modern windows from a big box store to replace the original aluminum windows in my sixty year old home. I had planned to install them myself with the help of my grandson and we had gotten one installed when he got a job offer, out of state, which he could not pass up. These windows were too heavy and bulky for me to handle myself and my search for an installer happily brought me to Jeff Petty and CW&E. Jeff's crew arrived on time, were polite, clean and efficient and except for a short lunch break, worked straight through to completion. There were no surprises with the price and my family and I are very happy with the results of their work. Whenever I might need help with a similar project, I will call CW&E again."

Glass Block Windows questions, answered by experts

DIY is possible for small projects, but professional installation ensures proper sealing, structural integrity, and a precise finish.

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.

Regular cleaning with non-abrasive cleaners helps prevent buildup and maintains clarity.

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

Glass block installation can be relatively expensive due to the range of material costs and the labor time to assemble this type of specialty window. The process proceeds slowly as the glass does not absorb moisture from mortar and silicone caulk takes longer to harden, leaving spacers to hold up the structure until the caulk or mortar begins to cure. Plus, if your current windows have structural issues or damage, you’ll need to repair them before beginning the project, increasing your bottom line.
