"My handyman recommended Aldefer glass as I need to replace the glass in my shower since it was an unusual size. When they were here to measure they mentioned they also could replace my kitchen windows. I was excited, one stop shopping. Well it’s two different departments... They had to come back and remeasure the windows, Another 2 week wait. They would not order until I gave them a 50% deposit (which is OK). They told me it would be 2 wks to get the glass then approx 2 weeks to install. I had to call numerous times to see if windows had arrived and schedule install. Bottomline my 4 wk anticipated install was over 2 months, then the middle glass in the tempered shower shattered during install ( 2 phone calls and 4 Additional weeks later shower complete). Kitchen windows still not right. Flys keep getting stuck between window and screen so I can’t open 2 of 6 windows in my kitchen. Terrible customer service. I have several more windows that I need to replace, they will not get my business. Truly awful experience."

DiGiacomo Construction is family owned and operated. We've been in business in the Philadelphia and surrounding areas for over 20 years. We offer free estimates, veteran and senior citizen discounts and we are full licensed and insured. Quality, reliable workmanship at competitive prices are our top priority.

"Digiacomo construction was very professional in two jobs for us at our home. They demoed an old failing retaining wall and built a new wall to support a new garage. We also hired them to pour a new pad of concrete for the garage and a new pad for our back porch. They adjusted plans quickly and efficiently when an obstacle was encountered (our water line was where the original sonic tube would be) and the plan was updated to build around the line. I would generally not be able to be around to discuss plans so they would discuss work with my wife and we're always respectful to her when going over tasks and updates. We will hire them again in the future to complete work on our garden."

Glass Block questions, answered by experts

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

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.

Yes, many professionals provide custom-cut glass replacements for enclosures that require precise sizing.

If an individual block breaks, you can remove and replace it. This is a job for which you should contact a professional because the project is usually complex, involving you having to break the block further.

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.
