I had a new picture window with two smaller side windows replaced. First the sales rep was great, then they came and did measurements which were right on. Then the installer came and put in the windows. He was very professional and did an excellent job. I was so impressed it looked so good. I would hire them again in a minute for future work. Thank you.

I had a big picture window installed on May 11 2021. The experience was very pleasing. My tech Peter showed up on time and got right down to business. Peter was friendly and he explained what his scope of work would be and what to expect of it. He worked without a break he was really clean and he cleaned up his work space afterwards very well. He wore aRead More mask the entire time which I appreciate. His work was really productive and professional the window looked awesome, and seemed sturdy once Peter was done. He seemed to like his job had a good attitude with a smile even though my small yorkie barked at him the whole time.
Thanks! Feldco for having great windows and equally great people working that gives great customer service.

Picture window replacement.

By: on November 24th, 2020 Rating: 4

Feldco finished installing my new picture window today. It took almost 10 weeks rom start to finish, but I blame most of the delay on the Pandemic. The installers did a beautiful job they were polite, professional and the gentleman I talked to did wear a mask. Much appreciated! If the job would have been done sooner, I would have given them 5 stars. IRead More am very happy with the price and the product.

Great products, great service

First of all, I’ve been wanting to review my Feldco experience. However, I do not and will not use social media. That said, I’m happy to leave one here.
We got prices on the windows(38) and a sliding patio door. I had been shopping for a couple of years, so I had a few other bids. Feldco knocked the others out of the water. We decided to do theRead More siding as well. They escalated it to their “commercial “ associate. He gave us an excellent price AND gave us 3 year 0% on the whole deal.
I can not say enough good things about the window crew. Amazingly fast and efficient. The tin work they did was outstanding. Extremely pleased with the window installation.
Same story with the siding, except for 2 minor delays ( 1 mine the other crew illness). Again, very fast and efficient. Lots of things to work around, clever solutions. One humorous side note, after they had left, I was out with the dog admiring my “new” house. I got looking and noticed an electrical outlet was missing. I called the installer, he’s like WHAT ? They came right back out and took off several pieces of siding and found the “ missing” outlet. He even had the forethought to stop and get a new cover, figuring rightly, the old one had been tossed away.
All in all, we are extremely pleased. We got twice as many windows as our Pella bid for the same $. Yes, I know Pella makes great products, but twice as good- no way. We would definitely recommend Feldco to anyone. Hopefully, they pay their crews what they are worth.

Superb Experience with Sales Rep!

By: on October 29th, 2020 Rating: 5

I met with my sales rep, Mr. Kemp today. My experience with Marcus was delightful.

Mind you I am a single older lady who has endured various unpleasant contractor experiences over my 30 years in this house. Ugh!

Today was different. I received a fair quote for windows and doors by a sales rep who was knowledgeable, personable, respectful, and aRead More real credit to Feldco. I didn't feel condescension to the "little lady" as I had earlier that morning with another contractor for other renovations. Marcus quickly made it clear he valued me as a customer and left no detail out of his presentation.

As a result, I purchases several windows and am deciding on a few doors. I felt no upcharge pressure, nor did I feel Marcus left out any amenities that I could add if I so wished.

TBH, I was surprised at how accessible Feldco was from a price standpoint, coupled with their insanely comprehensive, transferrable warranty, and installation liability protections. It's like putting a lifetime warranty on chunks of your house (the windows).

They cannot come until a month or so out. Covid strikes again! However, based on the quality, price, and warranty, I'm happy to wait.

Marcus did a great job. Plus he gave me all his contact info so I need not fret if something should arise. So on top of everything else, peace of mind. Priceless.

I will report back when the work is done. Very happy customer so far.
