VERY WELL. I used this company last year for a small window, and was so pleased that I called them back for this much larger job.

This is an extremely professional and competent company. Rob our salesman came out to do the estimate and take rough measurements. He was on time and very thorough in enplaning the windows. He then submitted a formal written proposal outlining what was to be installed, how the installation...

With over 10 years of experience, Ritmo Construction, LLC, is the place for all of your addition, and remodeling needs. We take great pride in our extreme professionalism, timeliness, and superior customer service on every job. We develop lasting relationships, so that the next time service is needed, there is no question on who to call. Satisfaction guaranteed! Call us today!
"I'm ashamed that it has taken me this long to get around to writing a review for Alex and his team. What prompted this is he texted me this morning asking how we were, how everything was with the addition, and if anything needed addressing - who does that a year and a half after project completion? Easy answer - a person who you should work with, if given the opportunity. We knew Alex was "the guy" after we met him and got our initial quote. Before meting him, we received numerous outrageous quotes from (very) popular local contractors. In addition to the quotes being ridiculous, these contractors were also never confident in the job, which seemed odd to us, because the scope of the project didn't seem insane. Alex comes in, says no problem, verifies that it's totally possible, and a couple weeks later we have a vetted blue print and an exceptionally reasonable quote. When we decided to pull the trigger on dormering out our attic to add two rooms and a bathroom, we had little to no idea as to what the job really entailed (roofline, heat zoning, access to the rest of our house, etc.). Alex was in constant communication with us each step of the way, and in an extremely accommodating manner, where he gracefully put up with us changing our minds on certain things. Example, my wife decided we should have lights in the closet - the sheetrock was already up, but Alex said no problem and threw lights in there. A larger example - we decided that we should also finish the space above our garage - again, no problem. If you have a job, big or small, and are able to work with Alex and his team, I cannot recommend it enough. I believe building and maintaining client relationships is the life-blood of a successful business. It is clear as day that Alex has mastered this concept. This is a team you need in your corner."

FAQs for glass block window service projects in Duanesburg, NY
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
