As the nation’s largest full-service exterior home remodeler, we are backed by over 1,000+ Angi Super Service awards and more than one million happy customers. Why? Because we treat each job as an audition. An opportunity to prove ourselves to you. And the results speak for themselves. So make your home all it was meant to be with our unrivaled exterior services. Contact us today for a free, no obligation estimate on replacement windows, roofing, siding, doors, or attic insulation.

"Avoid Power Home Remodeling at all costs. This was one of the most frustrating experiences I’ve ever had with a company. I’ll be actively warning everyone I know to stay far away, and I truly hope this review helps others do the same. A representative from Powers came to my door and said they were doing work in the neighborhood. He offered a free quote on a new roof. I didn’t have time that day, so we scheduled a follow-up for Saturday morning. I assumed it would be straightforward—measure the roof, give me a quote. Oh, how wrong I was. On Saturday, a completely different representative showed up and proceeded to deliver a five-hour sales pitch. I made it clear from the start that I was only looking for a roof quote—but instead, I got a relentless push for add-ons like doors, gutters, and radiant barriers. He brought out props, used aggressive high-pressure tactics, and repeatedly tried to get me to sign on the spot—despite me stating multiple times that I wasn’t making any decisions that day. The entire experience felt deceptive, exhausting, and borderline coercive. I didn’t agree to a five-hour in-home ambush—I just wanted a quote. Power Home Remodeling will waste your time and try to pressure you into overpriced services, and make it extremely difficult to get them to leave, even after you’ve clearly said no."

At Window Nation, we know replacement windows. We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years. We opened our first showroom in Maryland in 2006, quickly growing to serve homeowners in cities across the country – and we’re not stopping there. We’re grateful for every homeowner who has trusted us to upgrade their most important asset: their home. We’ve learned a lot about home improvement over the years, but the most important thing we learned isn’t about window replacement. We learned the home improvement industry isn’t about offering the best windows, siding and doors; it’s about the relationships we build with our customers.

"We hire Window Nation to replace 10 windows at our house, after a few months one of the panel leaked and was defective. Window Nation replace the panel at no cost under their warranty. We are very satisfy with the process and would hire them again to replace the remaining windows at our house."

"Unprofessional visit. Showed up unannounced and we only knew they were there because one person stood 10 feet from our porch staring at us in through our living room window. My wife spent 10 minutes talking to them, they stated they had no business cards, they only had an appointment card but didn't present it. Honestly when you show up at someone's house you need some sort of identifier if your walking door to door in casual clothes. After the uncomfortable dead stare through the windows my wife and i have decided to post a No Solicitors sign. They didn't take no for an answer at first, pushing with more questions to circumvent the no she gave, as well as interrupted our dinner, as they showed up right at 6pm."

Mar­shall Roof­ing, Siding & Windows is a top roofing, sid­ing, win­dows, and gut­ters com­pany based in North­ern Vir­ginia. Throughout the years providing the highest level of cus­tomer ser­vice and 100% home­owner sat­is­fac­tion has been the pin­na­cle principle at Mar­shall Roof­ing Sid­ing & Win­dows. The belief that each and every home­owner deserves to receive good value for their money is the driving concept on the functions of the company. **Popular Returning Spring Promotion Coming Soon** (Inquire for additional details)

"It was time to replace my roof and I requested several estimates from roofing companies. I selected Marshall Roofing Siding and Windows. It was not the cheapest estimate but the estimate assessment by Mr. Chris Butler, of Marshall Roofing, was the most thorough. Mr. Butler inspected the roof, went into the attic (and found a bathroom vent venting into the attic instead of outside), went into my screened in porch to determine what kind of nails to use so that they would not come through the tongue and groove ceiling and he noticed some old satellite dishes that could be removed. Marshall roofing updated the proposal several times with all of my concerns and additions. This is great customer service! When it came to choosing a shingle color, we struggled to find the right color. Mr. Butler kindly offered to bring out additional shingle samples to us on a Friday afternoon. Again, above and beyond customer service. Mr. Butler also worked with us to find and install an attic fan specifically designed to be quiet when running. The job started promptly on time and was finished in two days. Mr. Butler came out as the job was wrapping up and when the crew finished packing up, on his own, he did a second magnetic sweep around my house to find any nails that may have been missed during the magnetic sweep performed by the crew. Again, great customer service! We are very happy with the workmanship and customer service that we received from Marshall Roofing and would highly recommend their services!!"

"NOVA Exteriors did a wonderful job replacing 3 exterior doors at our home. They checked every box one could ask for. Rob our sales rep was patient and understanding of our needs - even coming back a second time as we had a hard time deciding on what we wanted. Their team worked quickly and did a great job installing some beautiful new doors. We noticed after the installation that there were some imperfections on the hardware installed and they have agreed to replace them & their customer service was top notch. They responded quickly to some minor concerns and went above and beyond to fix the problem. While doors are never cheap, their price was right in line with other Provia vendors and 1/2 the price of Pella vendors. I'd highly recommend them."

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
