At Zen Windows, we think that finding replacement windows, sliding doors and entry doors for your home should be a simple, pleasant experience. Our team works closely with you via e-mail and phone to help shape the improvements you envision without ever having a salesperson visit your home. We offer award-winning, energy-efficient windows and doors, and provide a lifetime transferable product and installation warranty. Zen Windows sets our clients at ease with our No Down Payment Policy. You won't pay a penny until the job is completed. Simple, easy, stress-free...the way it should be.

"Bottom Line: This is the first time we have used this company, and they did excellent work for a reasonable price, and more importantly, built a huge amount of trust with the customer. Communication: Scheduling the initial estimate was easy, but the back-and-forth communication required to finalize the many detailed options was a bit slow; however, the owner Scott Halle interceded and timely communication continued throughout the rest of the process. Scoping Work: This is where Zen Windows really excels, primarily because of the vast knowledge of James Bond. We wanted to replace the single door with side transoms with something that would maximize the opening space. James expertly walked us through the options with cost and wall modification comparisons. In addition, the header above the current door was swelling and pinning the door, and James evaluated the issue, likely water seeping down from an unflashed deck, and provided peace of mind his guys could fix it on site during installation. Quality of Work: Frankly, 75-80% of contractors fail here for three primary reasons: a horrible handoff from the product specialist to the onsite project foreman, project foreman and workers making assumptions about details vice asking the customer, and lack of quality detailed work. The foreman excelled in these areas ensuring we were on the same page for various details such as casing, caulking, and external trim. In addition, he completely replaced the rotted wood structure above and along the sides of the door and added customer-provided insulation where there were gaps. To keep the project on track, they brought in another expert worker and management arrived to ensure the quality of work was high. The end product was beautiful. Pricing: Price was the best of three highly ranked Angie’s List companies. Zen Windows’ expertise, willingness to explain the details of the project, timely communication, and excellent work took the hassle out of this project."

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."

"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."

"Our review is based on the purchase (part 1) for replacing siding for both side of our home. Jacob L. was very professional, on time, and honest. He knows what he is selling. We learned a lot about our home during his presentation. Before we bought our home we paid for a professional home inspection. We thought our house inspector was very good but he did miss something---the siding on the sides of our home was installed extremely bad. Jacob pointed out so much that we just didn't know and should have be caught during our home inpection. Thanks Jacob!!"

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.

"What an amazing experience from start to finish! Initially, the sales rep took the time to explain every facet of the process, history and quality assurance of the company before, during and after installation of my windows. All next steps given were followed up promptly by a courteous customer service rep through emails and text messages. An expert came out and measured all windows for precise fitting. He then also made me aware of next steps. While I awaited for my windows to be custom made, I received periodic messages providing anticipated dates due to shortage of materials. Once my windows were ready for installation, a date and time was scheduled for a team to come to install the windows. My Oh MY!!! Did they send me the BEST crew ever!!! The team lead walked with me to each window location in my home to ensure the measured window would be installed in the right location per the measurement appearing on the window pane left by the measurer. The crew worked steadfastly throughout the day. They took a brief lunch break. The crew members paused to address any questions my sister or I had. They were polite and friendly. This crew completed the task just before a fierce thunderstorm rolled through the area. During the inspection walk, we noticed one window pane was broken. NO worries, the crew leader had already contacted headquarters to place a replacement order. In a day or so following the installation, a representative reached out to me to explain next steps! My home feels so much cozier and sound since the installation of the windows. I have had to make adjustments to my thermostat because my home stays cooler longer! Thank you for sending me YOUR BEST and for ensuring that I have received quality service from start to finish! Humbly, Malissa P."

Why choose ROI Construction? Our Gold Standard guarantee is 100% customer satisfaction, 100% of the time! - It's that simple. No need to keep looking for “Contractor near me,” we are the top local Maryland and DC family owned Exterior company (est. 1974) that delivers the best results and a positive return on investment in the area! ROI also does a final walkthrough of every-single-job to ensure that we deliver a superior finished product for every ROI customer!

"While I appreciate the company's attempt to rectify initial issues, our overall experience with this solar installation was unfortunately very unprofessional. The initial installation team demonstrated a lack of respect for our property, damaging plants, leaving debris (including an orange cone), and inappropriately using our private bathroom despite a readily available public restroom on the premises. Following my initial negative review, the company offered a Home Depot gift card as compensation, which wasn't particularly useful to us. They also offered to address some unrelated roof repairs they noticed, but I questioned why these weren't addressed during the original solar installation. Scheduling follow-up work proved equally frustrating. An appointment was scheduled for Wednesday, but the crew arrived a day early on Tuesday without prior communication. While I appreciated them attempting to complete the work ahead of schedule, they left the roof partially finished overnight, exposed to potential weather damage. Furthermore, the crew damaged another plant box during the Tuesday work and continued noisy work – including banging on the roof – until 8:30 PM on Wednesday, violating DC noise ordinances that typically require work to conclude by 7:30 PM. This put us at risk of a city violation. Throughout the entire process, communication was poor and the lack of consideration for our property and local regulations was deeply concerning. While I appreciate the attempt to make things right, the experience was ultimately not ideal and left us feeling very dissatisfied."

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
