    Proof of the call placed to American Thermal to make the appointment
    Sonya M.

    I found American Thermal Windows via a Google search and decided to call them primarily because of the positive online reviews. My condo association is looking to have a new custom exterior door installed so I called to schedule an appointment with one of their salesman. I spoke to the receptionist for about five minutes on 3/24 & made an appointment for 11:30am Tuesday (3/29). The young lady I spoke with said the gentleman (named RJ) would arrive between 11-11:30am. The time came and went... no one ever called and RJ didn't show up. My cell phone call log and the building security cameras surrounding the entire property support this fact. I didn't even bothering calling American Thermal to complain either because I knew I wouldn't hire them regardless of the excuse they provided. If their employees can't even be trusted to keep an initial sales appointment then heaven only knows what might happen once they have our money. Luckily, I work from home so their employee not showing up for the appointment wasn't too much of an inconvenience. But if I'd had to take off from work to meet with him I would've been pissed. A business being careless with a (potential) customer's time isn't a good look. It pretty much tells me everything I need to know about the company's business practices. I'm glad we dogged that bullet. Beware! Update - Apparently ATW claims that my appointment was for April 5th... I took notes during the call detailing the company name, appointment date, time and name of the salesman I'd be meeting with. The receptionist definitely stated the appointment was for March 29th. I wouldn't have made an appointment for April 5th because I'll be at a conference next week. Perhaps the receptionist thought she said April 5th instead of March 29th? Who knows? Going forward perhaps AWI should consider immediately following up via text or email with customers to confirm appointment details like many other businesses do. That would help ensure that situations like this one don't occur again.

    Really happy w our door and installation. Let me say that it was not cheap, but it was in keeping w the few other bids we were able to get. It wasn't that sexy of a job, and no one was beating down our doors to get this job. But they showed up to bid, followed thru, hit their timeline and did a great job installing the door, trimming it out, putting our security deadbolt in and reattaching the alarm contacts. They did exactly what we requested. Cleaned up nicely. Very pleased w their work.

    Joe Public S.

    Awful experience. Installed the wrong hardware that was originally ordered on the work order then made it seem like it was our fault. Zero accountability for their work, they then had to re-order the door slab and upon installation the door does not close flush to the frame, there is a draft coming through near the top of the door. Customer service is a joke, most of the people with the exception of one that I know of are extremely rude. I would not recommend ATWP, take your business elsewhere.

    Before and after.

    I highly recommend American Thermal Windows. The crew was professional, friendly, and cleaned up every spec if debris. I'll have them back again to do window work.

    UPDATED 11/21/19: After having my windows replaced by this company in November 2017, I discovered further leaking in February 2019. After multiple visits by the window company and reinstall of the product in July 2019, they washed their hands of the issue and wished me well (SEE REPLY ON PREVIOUS UPDATE). ATW was vehement that the issue was "pre-existing" and that their new product was only leaking because of an unknown issue with the balcony. After several months of trying to find a professional to come and assess the situation, a paving and concrete professional visited my home on 11/20/19 and discovered holes within the window frame that allowed water to seep in. I poured water onto the balcony and the water instantly poured into the hole. This is a massive oversight by the installation crew and the FOUR other representatives that visited my home earlier this year. It also proves without a shadow of a doubt that the new windows were, in fact, the issue. Photos that were submitted to ATW back in February 2019 show the holes and yet none of the individuals who returned noticed them. The paving professionals who visited yesterday took photos and sealed the holes with an expanding compound that blocks water from coming in. The paving company has also agreed to speak on their findings if necessary. The way that I have been treated by this company is outrageous. Belittling my claims and "wishing me well" even though the product and service I received were shoddy. Shame on American Thermal Windows.

We learned that the old windows were not even windows by today's standards, they were just huge panes of glass that gave no insulation. He measured the windows so quickly (like 2 minutes) that I wondered if the windows world 3 actually fit (they did!). The price was extremely reasonable; we had intended to get three estimates but my mom and I both lined Kris so much we decided to go with him right away. I chose a day for installation when Kris was going to be out of town on vacation so he let me decide if we wait to wait until he got back or if we wanted him to send his right hand man Daniel. We went with Daniel who showed up right on time on a cold morning. I thought removing the old badly cracked panes of glass would be very difficult. I was right but they got the old ones out quickly and the new ones in so fast and they finished about 30 minutes before their estimate. They only removed one window at a time and our house never got cold on a 33 degree day This was one of the best customer experiences for a project I have ever had. I chose EV Windows after asking CharGBT to find me a great window company with very good reviews and I'm so glad I did. I do not have one negative thing to say. I most strongly recommend Kris and his team.

I would strongly recommend Chris and his team to anyone looking to replace their windows at a competitive price.

They came out to measure everything we needed, quoted us on what we wanted and a few other optional windows as well since we were debating on doing everything at once. After selecting the quote for the windows we wanted to get done, a down payment was made and the windows were ordered. They came in a few weeks later and two of their team members came out to install them in the morning. Everything was done quickly and professionally with care. After the install, I had a question about one of the windows since it looked like there was a small crack at the top corner and they sent someone out to look at it right away. It turned out it was just some glue residue that was attached on the inside of the window that made it look like a crack and was easly scraped off with a razor blade. I definitley recommend using Semko as they provided a very reliable service and also beat out many other window companies with their competitive pricing.

It took about 3 weeks to be custom made and 1 day to install. The installers did an amazing job!

Here's how they stood out: They had excellent communication. From Angelo's estimate all the way to passing inspection, they were on top of their game. The estimate had every combination of options listed with exactly what they were going to do and photos of the planned work. We were assigned a field supervisor (Justin, I believe?) who would come out on the same day to inspect any issues we brought up. Our contact with the office via Cindy and Anthony was also superb and always timely. The work was done swiftly and well. The roofers were done before I got back from work. Siding and gutters are more involved, but they did excellent there as well and Roman et al. were excellent to work with, took feedback very well (see communication above), and were very hard and efficient workers. All in all, we were done with our project long before other houses in the same subdivision who had all signed up with doorknocker companies, and they delivered a high level of quality. To be clear, their estimate was slightly higher (my gut says 10% higher, but it's been a while since I reviewed the proposals) than some other offers we received, but for the work that we were doing, level of customization, and communication, we wouldn't make a different choice. Absolutely a pleasure to work with. Thank you, Siding and Windows Group!

I'm usually not one to spend time getting a bunch of quotes and just rely on Yelp reviews to make a purchasing decision, but this was pricey enough purchase that i figured I should do my due diligence.' Siding & Windows Group was one of the 4 companies I had come out for a quote. We ended up with them for a few reasons: - Their quote was competitive - They were able to spray paint the interior trim with our existing paint color - They were able to match the exterior trim as closely as possible to our windows outside - Anthony at Siding & Windows Group was very responsive We placed the order on August 22nd, which is my bday. I can't say new doors was what i wanted for my bday, but i guess this is being a homeowner in your 40s. The new doors weren't installed until November 6th and we just hoped for no big storms and got lucky. Anthony checked in a few times on when they'd be installed and pushed it back a few days due to other projects. The actual installation took about a day, which wasn't too bad. A week later they came to spray paint, which honestly seemed like a much bigger project than installing the doors. That took 2 days and went smoothly, although there was a little confusion about them not knowing what color to paint, etc. It turned out beautifully and while the doors look very similar to our old doors I like the look of these even better. The exterior finish isn't a perfect match, but i think a big part of that is our old paint on our windows as faded. One day we'll touch it all up, but for now we're looking forward to a break in paying for anything for the house. I learned there are a lot of companies in the area for new windows/doors, but we were satisfied with this one and would use them again.
