“They came, they did their work. They just did their work, they cleaned up, and then they left. They did four windows. This is the first time I used them. I'd give them an A+ rating. It was great, I loved them. They were fine. I have recommended them.”

“The windows work great; I love them. They did the front, the kitchen, and the living room or the dining room. I'll grade them as an A.”

“I just love the windows and the door. It was good. They did the windows for almost the whole house and they did one door. I'll give them an A rating. I had no problems with them. They were excellent.”

“They did excellent work. There was a problem, but it got resolved. They have done window and door replacement. I would grade the experience with an A+. I would very likely recommend them.”

“They were on time, everything came in, they were very professional, they did a great job with the replacements. They were clean, neat, and on time. I was happy. I would give them an A+ overall. I couldn't have been happier.”

“They replaced all the windows in the basement and on the first floor. The only thing is the one window, in a terrible storm, sounded like it was leaking, but I couldn't find any water, but it sounded like it was leaking. I would grade the overall experience with an A+. I would highly recommend them to a friend, and I have already recommended them.”

“They came in, they did what they had to do. They cleaned up behind themselves and they left. They were professional. They installed a new front bay window for me. I would grade the experience with an A+. The customer service was full of a little confusion. I would be extremely likely to recommend them.”

“I liked everything, from the moment the salesperson got in the house to the moment the last installers went. It was outstanding. They did all seven windows and one big window,. I'd give them an A+ overall.”

“I liked their good customer service, and they backed up their product. They put a door and screen in for us. They deserve an A+. We would highly recommend them.”

“They were efficient, they worked well, and they worked quickly. Just happy with the windows. They installed windows in my whole house. I would say they get an A+. I would be extremely likely to recommend them.”

“I have another order which I am going to call them to install in September. They installed a new front window—they took the bay window out and put the window in. I liked everything about the company. Castle Windows deserves an A+. I would be extremely likely to recommend them.”

“Their work was very excellent. They explained to me exactly what they were doing for each window. I got new windows in. In the near future, I'm probably going to get some new windows and doors from them. I'd give them an A+ rating. I would recommend them.”

“They did everything in a really timely fashion. The guys did right and cleaned up. They did a real good job. They put all new windows in my house, and they also did the front door. I would rate them as an A. I would be extremely likely to recommend them.”

“One window cracked, and they came and repaired it. They replaced the part where it was cracked, I think it was the bottom part. They replaced 11 windows and installed 2 doors. I would rate the experience with an A. I would be extremely likely to recommend them.”

“We've had all our windows replaced and we were very satisfied with them. We had two doors installed. They made good on their warranty; however, they had to come out several times in order to do the job correctly. They did all of our windows, which was great, and they installed a front door and a back door for us. Both doors had some issues. I mean, they're really great to deal with, even when I was having the issues, so I guess I would give them an A rating.”

“We love the door. Everything is looking good, I love it. I think there were three guys. We replaced for both cosmetic reasons and the seals were broken on the door, we could see through it. They definitely deserve an A overall. I already have recommended them.”

“I liked them very much. I think they did 27 windows, no doors yet. I'll give them an A; I love the windows. So far there's no problems.”

“They put two doors in. The first door I have sliders and I put one slider in and I had an Renewal by Andersen slider. It's only good for ten years. It's wood inside and I guess it's like plastic on the outside, whatever they make the windows out of in doors. But Castle said it's a lifetime if anything ever breaks. It's lifetime, that's what I liked about it. I liked the door so much that I bought another one. I am extremely satisfied with everything. I would grade the overall experience with an A. I would be very likely to recommend them.”

“They installed all new windows in my whole house. I liked their windows. I would grade the overall experience with an A. I would be extremely likely to recommend them and have already recommended them.”

“Fifteen years ago, I had all my windows done. I was doing an addition, and I needed a door, and they came and did a good job. I would grade them as an A. They did more recent work about three months ago. I would be extremely likely to recommend them.”

“I thought that the person that helped us out, the young man that sold us the doors, we got doors from Castle, we thought that he was excellent in explaining everything and we felt very confident. When the people came to put them in, everything was as we expected, so no problems at all. I would give them an A grade. They cleaned up after themselves. I would recommend them.”

“I liked the windows and I like the clean look of the job that they did. They replaced windows in two rooms of my house. I'd say they get an A. I would be extremely likely to recommend them.”

“I liked everything about Castle Windows. They installed two picture windows in the front of the house. I would grade the overall experience with an A. I would be extremely likely to recommend them.”

“They replaced our upstairs windows. Everything is working perfectly.”

“They did good. Nothing's really leaked yet. We got a lot of things done. They did five windows and the deck door. They get an A+. The windows work nice, and you can pick them up with one hand and not have to use two hands to slide them up.”

“Quick service. They replaced windows for me. They deserve an A+.”

“I'd give them an A+ overall.”

“They're very efficient, they're informative, and they were very polite when they were here. We've had them here two years ago, also. Two years ago, it was my boys' bedroom windows and my kitchen window. This time, it was two living room windows and our dining room window. I'd give them an A+ grade.”

“I liked how they were quick. They did windows and doors over the whole house. It took them about a day's time. I'll give them an A+ rating.”

“I liked everyone I dealt with, actually, from the sales guy to the installation. It went smooth. It was a good experience. They replaced windows for me. I'd give them an A+.”

“They did very well, very well. I'd grade them as an A. They did windows for me.”

“The gentleman was good who installed the window for me. He measured everything that he needed to measure. I would grade the overall experience with an A. I would be very likely to recommend them to a friend or a colleague.”

“I liked everything. They did well, cleaned up after themselves, and did quick, easy work. I had a large stained window put in, two smaller windows, and a door. I'll give them an A.”

“There was just nothing bad. They did window replacement for me, and everything is looking up to expectations. I'd say they earned an A.”

“I'll give them an A overall. They installed windows.”

“They put in two big panel windows in the sliding door. I'd give them an A grade.”

“I would grade the overall experience with an A. The only thing that I wasn't satisfied with is the two guys who put windows in. They cracked my tub surround, which is old, I understood. But I didn't want moisture to get behind it, and I thought they would have done something with it, but they didn't do anything. They must have dropped a tool in my whole tub, took a chip out of it. They never followed up on that either.”

“They came in, repaired the window, cleaned up everything and it wasn't left to do after they left. Everything was satisfactory and complete and good. I would rate the experience with an A. I would be very likely to recommend them.”

“They were very professional and when they did the job, it was very organized and clean. They said it would only take a day, and it only took a day. They replaced ten windows. It's a two-family unit so they did half of it.”

“Their work was fine. No problems. Very responsive. If I ever needed anything, they were very responsive. They did mostly windows and one sliding door for me.”

“I had no problems at all. They're fine. I just had one room done. I think they're very good and I would give them an A.”

“Everything was done on time and per the quote. I had them put doors in, replace windows and they did the whole house over two different visits. They put in three doors. I'll give them an A rating.”

“We're satisfied with the job we had and we're not going to go any further with windows at this point. They installed windows, and I'd give them an A overall.”

“I'd say Castle Windows deserves an. They did windows.”

“Their job was well done. They installed windows. Everything is working up to expectations now. I would rate them as an A. I would be very likely to recommend them.”

“They did windows, and I'd give them an A overall.”

“They replaced some windows in the dining room and in the living room. I'd give them an A rating. I didn't have any issues.”

“I would give them an A. They replaced the windows in just one room.”

“The quality of the windows and doors is exceptional. The installation was done on time and with total professional workmanship. I have recommended Castle Windows to everyone who will listen. One of my friends has already bought some windows and is also satisfied with the windows and workmanship—A+.”

“Castle did a great job installing our new steel front entry door. It looks beautiful, and the installers were punctual, friendly, and efficient. We are totally happy with our decision to go with Castle—A+.”

“My whole experience with Castle Windows was great. The sales rep was knowledgeable about their product. The installers were polite, worked through the rain to install the windows, and did an excellent job cleaning up.”

“Outstanding job. I am very pleased with this purchase—A+.”

“Couldn't be happier. Thanks for a great experience.”

“Professionalism and a job well done!”

“Castle Windows did everything they said they would do. From the time we meet to discuss until the time the job was completed. Excellent service.”

“Overall, very good experience. Only issue was a few small leaks when it rained really hard. I believe I fixed the problem with a little additional caulk.”

“The windows keep our house cooler in the summer and warmer in the winter. There is no air escaping or coming in the bottom of the windows. They are easy to clean and open. The slider door provides great light in our kitchen. Really enjoy them!”

“We are extremely impressed. We were very pleased with every aspect of this installation.”

“The work looked good! I gave a call, within 24 hr. They were on the way! Hope they stay around for a long time!”

“I would recommend Castle Window to anyone. They were very professional from the start duty and that includes the sales rep Chris Wilson. The windows are absolutely great. Thank you.”

“They did a very professional job in replacing our double front doors. We are very satisfied with the work. The only concern was the length of time between signing our contract and actually getting the job done. It was a several month wait. However, the company spontaneously offered us some free upgrades to make up for the long time we had to wait. Good customer care!”

“The salesman that sold us the windows and door was great. The working men that came out to install were OK, but not quite what I expected. I guess I expected men to come in a Castle Windows vehicle, wearing Castle Windows shirts, and all of them be able to speak English. Well, it was otherwise, and we were somewhat disappointed.”

“Windows operate very well and are easy to clean.”

“Due to a mix-up or another reason installation was 11/2 to 2 weeks later than previously stated but other than that I have no complaints. The installers were courteous and done good work. All seven windows were installed in one day which included new flashings and they made sure each widow was operating properly as they were installed. After they were done an installer went over everything on the operation of the windows.”

“After we had contracted to have new windows installed on our second floor (10 in all), I read some bad reviews and I was somewhat concerned. However, the installers were here on time. Installation was quick. They cleaned up everything before they left. About six weeks later, in Feb. we had a loose top cover over one window. I called Castle who advised when they would be here to correct. They were here on time and quickly resolved the problem. I LOVE the windows. Just got done cleaning all windows in house. The upstairs were cleaned in time at all. The downstairs, although fairly new (not Castle) took twice as long. Windows, installation and all personnel (starting with salesman who came to the house) I dealt with were great.”

“They were great.”

“I had all my windows replaced, and I had to have six sashes and a screen replaced. The first time around, everything was great except that none of the installers spoke English, so I couldn't ask them any of my questions. The second time around, with the sashes and screens, the man was very efficient and friendly and got the job done quickly.”

“Excellent service, great salesman, all around good company.”

“Excellent overall experience. We had 15 windows replaced and all completed in about 5 hours. Everything was left as if they were never here.”

“Windows fine. I had someone else at the house as I could not be there. However they kept changing the time when they would be there and that was frustrating, as the person at my house had a time they had to leave.”

“Extremely happy with Castle!”

“This is my second set of windows from Castle. They replaced all of the windows in my NJ home. Excellent service both times. I would highly recommend them.”

“Metal cover under front step coming off. A draft around molding of back door. Workers professional, and courteous.”

“They were very nice.”

“They showed up on time, quality work and did it within the time period the installer said he would.”

“They did a nice job on presenting the product and options possible. No hard sell or pressure. The door was orders and came in a very reasonable time. Installation was done very well and the end product is all we hoped for.”

“The window installers were very professional and there was no sign that they had even been in our home except for the new windows and sliders. The salesman gave a very informative presentation.”

“We had 15 Windows installed by 2 men in 6 hours! The men were very polite, knowledgeable and made sure they had protective covers over their shoes each time they came in the house. The windows are perfect! A very good investment to the value of our home. No more draft and blocks out outside noise! They look beautiful!”

“Everything went great except they missed their appointment day because their truck broke down. They showed up the next morning and replaced all windows in our house.”

“I am very pleased with my new doors! They look nice and are easy to open and shut. I have noticed that there is an improvement in the air conditioning inside the house due to the new sliding doors. Thank you!”

“We had two installers and they did a terrific job.”

“We are completely satisfied with our castle windows and the organic gas is great.”

“The installers were experts in their field. The installation was perfect from start to finish. The installers were experts in their field, friendly, personable and answered any questions I had during installation. I had some problems in regards to customer service returning my calls. Improvements could and should be made in this area.”

“We are very pleased with the end result, they did just what we wanted and in a timely manor. The finish carpenters were very proficient in their work and they very nice work. Love the hardware on the casement windows.”

“Love the quality of the doors and windows. Very awesome job. Thank you.”

“We've had Castle install windows on two separate occasions. They seem quality enough, but I did notice on the second round of installs the windows seemed to be slightly out of alignment where the pieces slide together, as if when they were sliding the frame together they didn't slide it all the way. Now they appear to have gaps in the finish. You'd think they wouldn't rush this and make sure the finish was closer to perfect since these are supposed to be guaranteed for life, but perhaps this cosmetic flaw is just that, cosmetic. Over all Castle is very good about honoring their warrantee and do want complete satisfaction. Their installation contractors vary, but we have always had a good experience with them.”

“We had Castles replace our 25 year old French patio door with a sliding door. I love the door! Our energy audit bill showed we came down to average instead of sky high. It blocks out the heat and is extremely well built. Installation was top notch.”

“I love my new windows. I think the team you guys having going for you don't change anything.”

“They replaced 10 windows in about half a day the workers were very good and communicated what was going on.”

“The crew did great and were very respectful.”

“Castle Windows replaced my windows and did an excellent job. The crew arrived on time and worked quickly and cleanly. The windows are efficient and easy to clean and maintain.”

“Good people. Good service. Good doors.”

“Overall we are very pleased with the product. Even on the hottest days, the windows remain cool to the touch—unlike the windows we replaced. We were treated courteously by all employees of Castle. We did have one major disappointment. We scheduled the work four weeks in advance and then Castle did not show up on the scheduled day—'hung up on another job.' It's hard to believe that the other job was scheduled before ours, because when Castle called to schedule the work, they wanted to do it immediately.”
