AndersenAvis 

I should have reported my issues years ago when we originally had the issue with Steve Mermalstine but - in 2023 we had an issue with Steve- who is sent in to push sales when you otherwise may not purchase. Andersen uses predatory sales tactics to push a sale of two bay windows in our older home. They demand an answer on the spot and if you don’t bite they continue to attack you with pricing. We eventually broke down and agreed. But We were never informed That the window installation process would leave us with smaller windows. Essentially We were whole heartedly upset with the process and product. We were never offered a solution but decided to look on the bright side and move on. After months of antagonizing text messages we agreed to an estimate for exterior doors - 2 to be exact. When Steve arrived he was upset that my husband wasn’t home- because he could not exact the same predatory sales tactic as before. So, before even seeing both doors I told him I would not be making a decision today. He retaliated by saying “well, this was a waist of my time, I could have told you over text this was going to be 10k per door.” I told him I was sorry for wasting his time and sent him on his way. Then tonight, he sauntered into a local restaurant that we frequent. He was pompous and lied about both interactions and then, on the spot threatened to put down our place of business to local residents. Again, should have said something when he lied about a window installation. I should have said something when he insulted me in my home a second time… but today I’m saying something because his lies and sheer lack of professionalism was not only deafening but also potentially detrimental to my place of employment - which has no bearing in any of this. Steve mermalstine of the Philadelphia/Coatesville area is not a nice person and he will openly lie to your face regarding Andersen windows/door- and then further insult your intelligence and integrity by lying again to say he Didn’t. Don’t get sold by this predatory company or the terrible people it employ's.

I ordered glass replacement may 27th and never received the order yet I called and they give me the run around I aso6asked to talk to a supervisor and they said not available and also gave my number for a call back that didn't happen I am not doing business with Anderson 4 anything

These windows melted my car and RV. STAY AWAY!!
The heat and sun that are reflected from these windows can damage and melt anything not metal. I have been going back and forth with the insurance company representing Andersen with no progress, just excuses. This happened five months ago. The damage from these windows has cost me thousands of dollars. Stay away from this company and windows. Protect your property!

Very disappointing experience with Andersen Windows & Doors. After payment, customer support became extremely difficult to deal with. Multiple emails, phone calls, and months of follow-up resulted in little to no resolution. Simple requests were repeatedly misunderstood, and communication was poor throughout the process. Based on my experience, I would not purchase from them again and cannot recommend them to other businesses.

I broke my new front window, ordered a replacement sash on 3/24/2026, I kept calling to get a ship date, I finally got told it shipped and when it would arrive. I scheduled the installer, the day it was to be here I received a call stating it was back ordered. I then received a message that it arrived the next week but was refused due to damage. The new shipment date is now in July. I spent over 60k to have new Anderson windows installed, had I known their customer service was this poor I would have picked a different window company! In short, anyone needing windows do your upfront investigation and pick another window line such as Pella, Kobe or Weathershield to avoid the poor customer service!

Andersen can not claim they have customer service. Customers are irrelevant to them. Still waiting for an order placed 5/14. They provide invalid tracking numbers. I received an email which they stated was delivered on 5/22. It wasn't. Using information from Anderson’s website shows there’s an unexplained delay. It’s still sitting at a suburb 5 miles away. They lie.

Good lord. We have an older 850 sq ft home with 8 windows max and I mean smallish windows. Their rep quoted us $32K for new windows!
What a total scam!

Worst company in the world - I've dealt with them directly since 2006 - first home build resulted in a lawsuite we won because they had so many defective windows and refused to honor their warranty. Fast forward and I just bought a home with of course brand new andersen - several defects found by andersen's own inspector and they are once again not honoring their warranty so back to court we go. Avoid them at all costs. The folks there have all been really nice but they gaslight you and you will not get any warranty honored.

My wife solicited a consultation & price quote from Anderson. For just 7 windows & 1 sliding glass door, the quote was a stunning EIGHTY-THOUSAND dollars! I thought they must have inadvertently added a zero. No thanks, Ander$on.

Andersen doors EMCO customer services es lo peor que puede haber no recomiendo esta compañia tengan cuidado hablan de garantia no existe devolver el producto buena suerte llamar customer services suerte y es mejor que hagas un curso no de english si no de Chinese indu que locura

I have used Anderson windows for 30 years. I will Never. Buy another one. We had a patio door with the internal shades installed in February, on the 25th, 2026. It was a 5k$ door- which of course included the install. I was hesitant to buy a patio door with the shades on the inside, because what happens when they break? They have a good warranty. So I bought it. On March 26th, was raising up the shade with the slider and it broke. Not only broke the slider, but the track it was on is also coming off. I called the warranty number, was on the phone with them for 45 minutes /. They accessed my phone, they had me take measurements, they had me go inside and outside to see the door. The part is covered. However to have a technician come out to evaluate the door.. Four HUNDRED dollars. I said no. And I will no longer buy Anderson. Nor will I recommend Anderson. If you are looking for a patio door, do not buy the one with the shades on the inside.

Anderson windows are the absolute worst! When I purchased my home the Anderson windows had been all replaced new within 4 years. I had a huge 70 “ window replaced within the first year of purchasing under warranty due to a seal fail. I had to pay for labor. The entire window was discolored and had bubbles in it. That was the end of my warranty. Now I’am stuck with windows that all leak air very badly in the winter. I can’t close them correctly, top up all the way up and bottom down all the way down, so 90% of my windows don’t lock. Please, please do not waste your money on these windows, from someone who has no choice but to live with their defective windows at this point.

Total scam. Order 2 x shoes in size 7. They shipped one in size 8 and one in size 9. Now they are trying to charge me for shipping product back. Avoid this company. Pretending to be a Canadian company. NOT!!!

The Andersen cord operated enclosed mini blind windows are awful. From the start, the blinds will not close all the way. The salesman told me straight faced that the Pella magnetic windows with enclosed blinds could "wear out". I told him I didn't think magnets would do that. Ridiculous but my spouse wanted to do business with this dealer and not Pella so we bought 12 various size windows. From the start, the blinds rarely would close all the way and several barely move. My friend's magnetic Pella are twice as old and still work flawlessly. We had ours installed in 2020.

1-Star Review: Misleading Sales Practices and Poor Customer Service

We had high expectations for Andersen Windows & Doors given their reputation, but our experience was deeply disappointing and unprofessional.

The Issue: During our initial consultation, salesperson Stephen explicitly promised an 8-10 week lead time for our front door installation. We made our purchasing decision based on this timeline. After placing our order, we were informed the actual timeline would be 16-20 weeks - literally double what we were promised.

Their Response: When we escalated this significant discrepancy to management, we were offered only a token $500 discount despite the material misrepresentation of delivery timelines. Sidney from their team was unprofessional and dismissive throughout our attempts to resolve the situation.

The Outcome: Rather than work with us to find a reasonable solution for their misleading sales practices, Andersen chose to walk away from the business entirely.

This experience suggests either poor internal communication between sales and operations, or intentional bait-and-switch tactics. Either way, customers deserve accurate information upfront, not promises that can't be kept.

We cannot recommend Andersen Windows & Doors based on this experience. Shop elsewhere if timeline reliability and honest communication matter to you.

The door looks decent but after a few years the hinges start to give and the door sags and drags on the frame so the hinges need adjusted, I adjusted them to the max. After that I had to have a person from Anderson come install new hinges and a new seal which cost me $300, then a few years later which is now it’s happening again. I would not recommend Anderson doors.

Frustrating all around.

We purchased a home with Andersen windows and doors last August. I wanted to learn about warranty details because one of the doors leaks when it rains. They quoted me $700 to come out and “tune up” the doors which were installed within the last four years. Of course, a few months later, one of the doorhandles just completely came off. You would expect that with such a “superior” product, you would also get high-end support. If something breaks, you have to help them identify the piece over the phone. Apparently they don’t just have a service where a technician can come out and assist you. You would think that if companies that provide dining tables are willing to do that, companies that provide products that are imperative to your home’s safety and function could also include such a service. Safe to say, we have called them three times and every time they have sent us the wrong parts to fix our door. I have Google image searched the part, and because they are so close to the chest about their products, you cannot just locate and purchase a replacement. But I argue you also shouldn’t have to - especially when your door is under warranty. Things happen, parts break - but Andersen seems to rely too heavily on things not going wrong. And when things do, they really drop the ball. There’s no problem with believing that your company provides a high quality product and standing by it - but you can’t call yourself a high quality company without accounting for the moments that your product fails.

The bottom of screen door sticks. The handle is cheap quality. The lock and door latch malfunction. Tried to replace handle where I bought it. That comes without lock and latch parts. You have to buy the oh so expensive complete handle with lock and latch from Andersen. Customer service is horrible. When I saw the
Inceased price on bank than I was quoted I tried to . cancel I was told I had 1 HOUR TO CANCEL ORDER. It had been 2 hours. Buy a better brand!

New windows by Anderson have broken seals. Probably happened during rough installation. They also leak air. Anderson says they will NOThonor their warranty. Garbage products. STAY AWAY FROM THEM!!

We built a new home in February 2024 in which the builder installed Andersen 100 series windows. From the first day we moved in, we experienced extreme temperature variations between rooms. With outside temperatures below 25, some rooms were 60 degrees. In summer with outside temperatures over 90, some rooms were 80 degrees. The thermostat remains set at 70 degrees.
After thorough investigation with an infrared temperature gun and thermometers, the windows turned out to be the source of the problem. We contacted the builder, and they found no issues with installation and told us they have installed these windows in other houses with no prior complaints.
After numerous calls to Andersen Customer Service, my case was escalated to a supervisor who reluctantly agreed to send a representative out to inspect the windows. He only performed a visual inspection of the inside and outside of the windows and said he found no problem. No tests were done to see if the windows met manufacturing specifications. The representative also stated that was the best I could expect out of Andersen 100 series windows.
These windows are manufactured with Low-E glass and are Argon gas filled and are Energy Star Certified. Is this normal performance for an Andersen 100-series window or are my windows defective? Does Andersen really market and sell windows that are this low a quality for a new construction home?
There’s an undeniable problem, but Andersen is not willing to acknowledge the possibility of their windows being at fault. To make matters worse, they refuse to work with customers to reach a resolution to the problem.
We are left with one option: replace all the windows in a 9-month-old house. You can be sure the replacement windows will not be Andersen.
If you’re looking for new windows, do your research and make sure you buy from a company that has a good record of quality products and customer support. Andersen is not that kind of company.
