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."

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."

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.
"The salesman was late. The person taking measurements missed a window rushing before his vacation. Which in turn delayed our project 2 weeks. The installers damaged our new porch and installed 5 defective windows. We have had 0 updates on how our windows and home will he repaired but we have received numerous. Text, emails, and posted mail begging for 5 stars including a gift card as a thanks. It has now been over 5 months and we still have windows that need to be replaced and Window Nation has fraudulently told the finance department the job is complete so we now need to pay for a job that is not completed. Avoid this company if possible."

Security door installation services FAQs
The average cost of a home security system is about $700, ranging from $280 to $1,150. Costs to consider include equipment, surveillance fees, and other additional features. Cost factors that determine your system’s price include the type of security system, materials, labor, activation fees, monthly fees, and permits. Additional features and upgrades may include:
Video surveillance monitoring: $40–$65 per month
Smart home locks: $150
Smart home lighting: $15–$90
Smart smoke, fire, and carbon monoxide alarms: $35–$100
Smart thermostat: $130–$500
The average cost to install a door is around $1,100, but you could pay anywhere from $150 for a hollow-core interior door installation up to $2,000 or a high-end exterior door installation. There are a few cost factors to consider to get an accurate price, including whether your wall opening exists, the type of door, the quality and security of the door, whether you need to replace the frame, and the door size. You can expect to pay $150 to $700 for a standard 36-by-80-inch door and between $400 and $1,600 for an 80-by-48-inch door.
Yes, a home security system can be worth it for your peace of mind alone, but it can also save you up to 20% on your home insurance. The insurance savings will help defray the initial setup costs and subscription costs over time. Locations with higher crime rates also make home security systems a valuable investment, but it ultimately depends on your personal preferences and asset values.
Door installation usually takes three and four hours, including removing the old door and frame, fitting the new door and frame in place, shimming it to make sure it’s perfectly level, and making adjustments to the hinges and locking mechanisms to ensure proper functionality. A door-hanging professional can replace an interior door in between one and two hours. Door installation will take significantly longer if your installer needs to create a wall opening, and it can take less time if the existing door frame remains.
It’s possible to install a door yourself if the wall opening already exists, but the work is rather complicated, and a professional installation is usually well worth the investment. For your door to work and close properly, you’ll need to shim and level the door frame in your wall perfectly, which can be difficult. Additionally, we recommend you always hire a professional door installer to place an exterior door, as mistakes during the installation process can lead to poor security for your home.
