"I was looking to repair the putty around the panes on a 1930s vintage clear glass window and was afraid I got someone who specialized in stained glass and wouldn't want my job but he did a great job and even helped me with a second window I had forgotten about (only shows from the outside but needed same attention). Very flexible, very personable, a pleasure to work with. Thanks, Ken!"

"I brought my 2009 Toyota Camry to Tint King. They tinted all four doors and the back window. I chose their better quality product as I plan to have this car along time. The job took about and hour and a half. I waited onsite. It looks great. Real nice job. However the inside of my trunk was soaking wet after the job. Not sure how that happened but  I wish they would have cleaned up after themselves. I kinda wish that I had chosen a darker tint for the back doors and window but it is hard to tell how it is going to look until its done. I am happy with the job. It has been 3 months and no problems. The car looks great. If you go there they are around the back of the building at a garage bay not in the office part of the building.

"Terrific. There is noting she doesn't know about tiles. She did a great job cleaning and gave me the name of the tool and cleaner that she used. so next time I can do it myself. She advised me on what grout to buy, the color and a grout paint to be sure the old and new grout would be the same. And gave me a very good price for the re-grouting. She worked hard and efficiently and cheerfully.,"

"We had an old pool on our property that had been unused and severely neglected for more than twenty years - it actually had trees growing in it. When we decided we wanted to try and salvage it, I called several pool companies before a friend recommended Louis Ranieri. The other companies never even bothered to call us back, but Lou returned my call within an hour and was at my home the following weekend to assess the job and give me a quote. Lou and Lourdes explained all our options in detail, kept us informed at every stage of the job, and promptly returned my calls. They went above and beyond to make sure we were happy with everything. Andrew worked from dawn to dusk to make sure everything was done right and in a timely manner. I am so glad we found Ranieri Construction and highly recommend them to anyone needing a pool renovation."

Glass Block FAQs, answered by experts

Heavy glass tends to be more expensive than thin glass because it is stronger and more durable. In most cases, ¼-inch-thick glass is ideal for mirrors, and ⅛-inch-thick glass is ideal for residential windows. Heavier glass isn’t always necessary, and can be more challenging to hang or install. Work with a local window installation pro for replacement or new construction windows.

Although glass block windows are made of multiple layers of thick glass, they can still break. If an individual block shatters, it can be removed and replaced, but this is a job for a window repair professional. The project is often complex and may require breaking the block further for removal. Do not attempt to handle it yourself, as the broken glass can be dangerously sharp. A professional will have the necessary tools and expertise to replace the broken glass block quickly and safely. Before hiring, confirm that the repair pro has experience with this specific type of window.

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

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.
