"Michael loves glass and finds beauty in its many incarnations. He created an exquisite front door piece for my house 9 years ago. All that door has done is look gorgeous. Haven't had a lick of trouble with it. And, Michael repaired an old glass tile for me too -- at cost even -- because he appreciated it as much as I do. The company also made glass inserts for cabinet doors which are lovely - more banal than the dramatic entrance but equally trouble free. I would hire them again in a heart beat."

"After dealing with frequent roof repairs, we finally decided on a complete replacement for our Livermore home. Avi kept us informed every step of the way, and the finished roof exceeded our expectations. It's made a noticeable difference during hot summer days."

"I absolutely love how my shower turned out! Everything looks so beautiful, clean, and modern. The attention to detail really shows, from the gorgeous tile work to the glass doors and fixtures. I especially love the built-in bench and the handheld shower, which make the space both stylish and practical. The whole shower feels so much more open and luxurious than I imagined. I’m really happy with the results and couldn’t be more pleased with how everything came together. I would definitely recommend!"

"Our sliding glass door became a beast! It was so hard to slide, we avoided using it. I called around to the other vendors on Angie's List, as well as those on the internet. Affordable Sliding Door gave the best price (& then took $10 off of that price, honoring their Angie's List coupon.) They were available the next day but we weren't able to work that into our schedule. So, they came early the next week, on time, as scheduled. Our door now works perfectly & we were so satisfied, that I just called them back to schedule an appointment for our son's home -- who has been suffering a long time with his beastly sliding door. DON'T SUFFER WITH A DEFECTIVE SLIDING GLASS DOOR! The $165 price makes this repair a must!

"Tony was extremely professional and responsive. He came out to measure the same day I called and then offered to do the install on Saturday as soon as the glass was ready. He showed up on time, did the job well."

"Chris did a great job replacing the sliding glass door and window installation. A lot of attention was given to the details and workmanship. The Milgard product is superior for the price. We would highly recommend this company."

Glass Block FAQs, answered by experts

Glass block windows typically last for 15 to 30 years, which is slightly less than the 20- to 50-year lifespan of standard windows. You can extend their life by resealing them every few years. Professional installation is also key to ensuring the windows are placed correctly and will function properly for years to come. A professional installer will have the necessary skills, tools, and knowledge to install these features and can identify potential issues like damaged frames or cramped areas during a consultation.

Yes, professionals can install decorative or colored glass block patterns for a unique look.

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.

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. 

New glass costs anywhere from $3 to $100 per square foot. More specifically, tempered and insulated glass—a common option for sliding glass doors—costs between $10 and $14 per square foot.
