Air-Serv was contacted on short notice to install a vent pipe from the basement through the roof of our 1 story house. JR accommodated our short schedule window, showed up on the date requested at the time requested and finished the work so we wouldn't be without hot water following the...

The storm window was ready when they said it would be so I took it home and found the hole for the attachment was cut too long so it would not stay in the storm window. Also the entire storm window was cut just enough short so that flying critters could get in between the top of it and the...

DaBella is the leading home improvement company in the United States. With more than 23 offices throughout the United States, we're striving to transform home improvement services. We work with you to create value in your home by providing outstanding service and premium products for roofing, siding, windows, and bath replacement systems. Since 2011, DaBella has grown to become one of the largest home improvement services companies in the United States. "Our core purpose is to care for families and their homes. We strive to provide the best customer experience and the best environment for our growing workforce," said CEO, Donnie McMillan, Jr. "The explosive growth we have achieved in such a short time period is an incredible story in and of itself. It was only possible because we created a culture committed to helping people realize their vision. Not only the career goals of our own people at DaBella, but also for those homeowners who we serve every day." In our industry, it's common for people to talk about the dream of one day owning their own business, often driven by the desire to make a lot of money. The start to our story, however, is different. It entails a motivated, young family who had worked in the home improvement industry but envisioned a different kind of home services company. The goal was not just to build a business, but to create an extended family, where employees, suppliers and most importantly, customers, were part of the family. Not coincidently, the company was founded at the same time as the family was blessed with twins. In fact, the name of the company comes from a combination of their names -- David and Isabella. But DaBella is so much more than a company's name. From the beginning it has been a second family name for employees. It's the nameplate of a company who works in the name of families.

FAQs for glass block window service projects in Fort Harrison, MT
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
