"We hired Unicorp to change front door because of superb review on Angi, but disappointed. 1. It's a small company using subcontractors to do its work; Contrary to its claim, those subcontractors DO NOT work exclusively for Unicorp. 2. After subcontractors got paid, you will not see them again for the job. The service team seems only one person (JR). It is hard to make an appt, since he has to supervise a lot of subcontractors' work, and only do service when he is supervising near you. Specific problems: -Ghost swing after installation (i.e. door swings to close by itself). Had to request adjustment at least twice. -Fainted finish after a few years while still in warranty, but we were advised to paint ourselves. -Very thin layer of finish, and very easy to get scratch to show white underline color; -Have PROBLEM to LOCK the door. After it was "fixed", problem showed again. -Subcontractor used wood with black stains, suspect mold, to install the door; Brand new door had minor defect."

Glass block window services FAQs
If you have a problem with your window, such as broken glass, minor leaks, or a problem with your window being stuck, repairing the broken part might be a cheaper option than replacing the entire window. However, if you have a deteriorating window frame or major leaks, buying a new window will be the better long-term solution.
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
Window replacement costs between $180 and $410 per window, or an average of $280 per window. However, your specific replacement job could cost as little as $100 or as much as $750. Factors such as frame material, the number of windows you need, and the type of glass you order all impact the overall cost. For example, simple double-glazed windows will cost $3 to $6 per square foot, but the stronger tempered glass ranges from $12 to $14 per square foot.
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.
The average cost to install glass block windows is about $710, ranging from $460 to $1,000, depending on the size and design of the window, installation type, and location. Different styles of glass blocks also impact the cost:
Clear glass blocks: $10–$30 per block
Colored glass blocks: $25–$40 per block
Acrylic glass blocks: $15–$25 per block
Wavy glass blocks: $10–$30 per block
Alpha glass blocks: $15–$25 per block
Ice glass blocks: $20–$35 per block
Diamond glass blocks: $20–$75 per block
Frosted glass blocks: $30–$35 per block
