Their warranty is WORTHLESS. They sent a defective part and won’t replace it. Then they said the damage to the frame was because we didn't install the part right away. Nothing like being gaslighted by this company. They have had every excuse to deny our claims and refuse to send parts. They claim these full glass storm doors 96” tall 36” wide are a homeowner do it yourself project. I am so glad we didn’t spend the big bucks to have Anderson windows installed when we built our home. At least Milguard will honor their warranty.

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.

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.
