"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!!"

"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."

He thought he was dealing with an uninformed senior and I believe this was a clear case of elder abuse and a scam."

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."

"Beware: company recently sold beginning of 2024 to new owners. Not same reputable company it used to be! This has been an absolute nightmare experience. This company has no idea what they are doing and poor customer service / management. We are building a 4 season room and ordered 19 windows totaling about $19,000. Contract signed December 8, 2023. Windows measured January 8, 2024 and told about 7-9 weeks until job completion. Windows had to be remeasured February 28th as no one noticed the measurements were not correct / order sitting on a desk. On installation day, 2 windows were incorrect. Was told replacement windows was supposed to be rushed ordered 2 weeks and promised “top priority” by manager Alen D to get them installed (April 9th) – only to have it delayed another 6 weeks (May 21+22) installed. Windows took 19 weeks from the day they were supposed to have been “ordered”. Communication with office staff and “managers” extremely poor and we were ghosted multiple times."

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
