Brian and Ken did an excellent job replacing windows in my home. I do home improvement work for others and know what to look for. I was on the ladder when Ken wasn’t and watched how they took care of damage caused by water. They always cleaned up any mess they made immediately before it got tracked around. The miters and finish work were excellent and my wife and I couldn’t be happier with the finished work.

Our experience with Window Perfections was perfection! We had two windows removed and replaced with one window in our bathroom, and when the crew was finished the bathroom ws spotless and from the outside the siding was done so well you couldn't tell anything had happened! They even searched and found the one supplier that had the exact siding, even though the house was built in 1999. They went above and beyond for us and they will for you too.

We have been quite happy with our windows! It was an amazing experience having them installed: the workers were all very respectful, efficient, and clean. In fact, they left the place cleaner than when they arrived! It was wonderfully effortless for us. 10/10 would 100% recommend!

We had a local box company put windows and door in ten year ago thinking we wouldn’t need to replace them . Unfortunately they were lousy . We met Jacob at a craft show and we shared with him our problems and he promised that he had great windows snd door that would solve it. We hesitated but we gave in. He came to our home showed us the windows and the price but promised it will make our home more valuable and a great investment. Then we met the installer, we were so impressed with their professionalism and knowledge. The way they finished each step of the installation and detail to everything was amazing. They worked very well together. They were very polite and respectful of us snd our property. I give Jacob snd the boys a 10 . One last thing, THANk YOU to everyone who made it possible taking care of our home snd making last minute changes. I’ll recommend Window Perfection to everyone ! A #10 yo everyone !

A heartfelt thank you to Window Perfections for their phenomenal work on this intricate project! Their professionalism and attention to detail are a shining example of excellence, and their kindness in fixing the woodpecker hole is truly uplifting. Their ability to complete the job in just 2 days is a remarkable feat. If you're in need of window or door replacements, please let me know and I'll be more than happy to provide a referral!

The windows took longer to be delivered than expected but the quality seems great. No longer feel any drafts. I absolutely love the look of them. The installers were very professional, respectful of our property, and took pride in the quality of work they did. They were very accommodating with the children and animals. I would and will be recommending them to friends and family.

A shout out to window perfection for a fantastic job. They replaced all my windows in my house. Great job. They even came back and fixed things that wasn't even thier fault, and didn't even charge me a dime. I would recommend them to anyone. Thank you guys.

We highly recommend Window Perfections. What a pleasure to do business with these people. From the initial sales consultation to the competition of the installation everything was done in the most professional manor. The product they carry is of very high quality. The sales team is knowledgeable and answered all of our questions. The installers exceeded the term “ordinary workmanship”, they were meticulous. We could not be happier.

We had 6 windows replaced in our home on 09/04/25. We stopped in the office and talked to Marissa to set up an appointment. Mark and Marissa came to our home to talk to us. They were very friendly and explained everything thoroughly to us,as well as showing us examples of the windows we were considering. There were no hard sell tactics, just a description of the windows and the price to complete the installation. To be honest, we were not looking to spend a lot of money. When we found out that it was going to cost a little more than we wanted to spend at this time, the Mrs and I discussed what we wanted to do. We decided that if they were as good as advertised, we would do it. We were so glad we did. Brian, Ken,and Jim were so professional, courteous and a pleasure to work with. They covered everything so they didn't make a mess, and they always removed their shoes when they had to walk where they couldn't cover. They cleaned everything up where they worked and a little more!! We couldn't be any happier and I would highly recommend them!! P.S. I would like to add that they went above and beyond what we were expecting for the finished installation. The care that taken to make sure the inside and outside trim was perfect was phenomenal!!

Mark replaced 17 very large windows for us at our church social hall in Dysart PA and the guys did a fantastic job. The detail work they had to do was excellent and we are very pleased.

Mark and the team at Window Perfections put in four 94 x 54 windows in our family room. From the first time we met his team we were impressed. They take the time to listen to what you want and then make recommendations. They aren't in a hurry and don't pressure you into a sale. They want you to be happy with the end product- and we certainly were!! The two guys that installed the windows could not have been nicer and they did an excellent job- when they completed all four and cleaned up you would never know they were even there. They had everything cleaned up and even contact me prior to leaving to see if I had any questions (I was at work).Mark came by today and took some pictures and spent more time checking the windows and making certain we were satisfied with the work. We love our windows and highly recommend Window Perfections. We have more windows to replace and they will be the company we will use.Thank you to the team that did our windows! Great work and great quality!!Corey and Diana Megon

We had several room windows installed as well as a kitchen window from Window Perfections. The crew of workers did an impeccable job of installation, follow through, and cleanup. We highly recommend this company and installers to anyone ready to install new windows in their home. We were so impressed by the respect they provided to our home as they tore out the old windows and installed the new triple pane windows. A road worker noticed the new windows just yesterday and commented on the look of the windows and, also, how well the capping was done for the windows. He was so impressed. You will not be disappointed if you hire this company to install your windows. Thank you Window Perfection for your wonderful work.

We've had Mark and his crew replace all of our windows over the past two years. We were so pleased with the first group that we had them replace the rest this year. They did a fantastic job from the estimate, to the measurements to the install. Everyone was very friendly and courteous. But most of all they were extremely clean and conscientious about tracking dirt onto our new flooring and carpets. They laid drop clothes in every room and took shoes off to do it. They totally cleaned up afterward and took everything. They didn't try to stuff things into our garbage! They do superior work, do not cut corners, and install quality product. We love the new windows and highly recommend them to install yours.

2025-06-22T23:27:17.921Z

We are writing this review to express our sincere gratitude for your excellent work on our window installation. Your attention to detail was truly impressive. Brian, Kenny, Jim and Dom, your professionalism and commitment to quality and detail were evident throughout the project. We look forward to collaborating with you on future projects. We highly recommend Window Perfection to anyone interested in new windows. Everything was beyond our expectations. Thank You, Hank and Barb Williams

I had an outstanding experience every step of the way with Window Perfections!! I HIGHLY recommend you speak with Mark. He is a straight shooter and everything he told me unfolded afterward exactly as he originally said. His installation team was incredibly professional and treated my home with the utmost respect.I am writing this review six months after replacing all of the original windows on the first floor of my 1960s ranch home. The energy savings were felt even before they finished the two-day job. The project occurred during an early-August heat wave, and the cooling that my home experienced was noticeable that same day. These Okna brand windows blocked out the heat of the sun from ratcheting up the temperature in every room of my home. For the remainder of August and September, I turned on my AC a lot less often than I expected because the inside of the house was very comfortable.More importantly, the wintertime energy savings were even more apparent. My heating bill from Dec. 2024 was slightly lower than the one from Dec. 2023 -- despite it being an average of 7 degrees colder in 2024 and a rate increase from my natural gas supplier. Mind-blowing!!Other major benefits I've noticed over the last six months is a significant reduction in road noise (I live near a heavily trafficked road in State College) and other outside sounds. Plus, I think they just plain look nicer and are far easier to maneuver than other vinyl windows I've seen in other homes. Ignore the reputation vinyl has, these are premium windows!Once again, I can't recommend Window Perfections enough. Do yourself a favor and give them a call if you are looking to upgrade your home.

Jacob, came to our home to explain and give estimate is the best, he by far knows what he is talking about. For such a young man just starting out he is knowledgeable and believes in this product. He could not have been any nicer to us, and very friendly. I am glad that we chose Window Perfections, and I would tell anyone that is looking for windows to give them a call.Our Job is done, and I can't say enough about the windows and the job that their employees have done. Their employees are so well mannered and polite. The windows are very nice. Thank you for making our house look great.

2024-10-04T18:58:11.897Z

We just had windows installed throughout our one level home. The experience was great right from the beginning from talking to a salesperson, to Mark who provided an estimate, to Brian and his crew, Kenny, Jim and Dom who completed the installation. Everyone was pleasant and knowledgeable and made the process less painful than it could've been. Brian and crew were very respectful and carried out the promise of leaving both windows and areas around them clean. I highly recommend this company and their high-quality windows.

2024-08-03T14:35:17.296Z

I recently had Window Perfections install 20+ new windows in my home, and I couldn't be happier with the results. The entire process was smooth and exceeded my expectations.The installation crew Brian, Kenny, Jim, and Dom were amazing. They went above and beyond, even fixing 2 loose shingles as well. They arrived on time if not earlier, worked efficiently, and kept everything clean inside and out. They left no mess behind.The customer service was also very responsive and helpful throughout the project. Any questions I had were promptly answered, and they kept me informed every step of the way.The new windows look great and have made my home more energy-efficient. I've already noticed a difference in temperature regulation.The quality of the windows is top-notch, and the craftsmanship is evident in every detail. I appreciate the follow-up from the company to ensure everything was done to my satisfaction.I highly recommend Window Perfections for their excellent service and quality work. Thank you, Windows Perfection, for a job well done!

2024-07-21T14:49:07.199Z

We are very pleased with their work. The craftsmanship and professionalism is second to none. When they left for the day, they cleaned up so well that you wouldn’t have known they were here.As for the windows themselves, it was well worth the investment. Right away, we could tell the difference in temperature and sound.We’ve only had the windows for a few weeks and have referred them numerous times.

2024-06-28T22:39:15.265Z

Window Perfections recently replaced double windows in our kitchen with a beautiful sliding glass door. The process was simple from start to finish. Mark helped us pick out the door, and then two of his crew members came the next day to measure the space. Bonnie was very helpful with scheduling and working around competing projects. The day of the door installation was seamless. The crew removed the windows and replaced the door the same day. They were extremely kind, efficient, and left our house cleaner than they found it. A job well done!

2024-06-24T21:20:35.095Z

We had 20 windows replaced. Mark was very professional and knowledgeable at the estimate appointment. Excellent job on the installation. Workers were very courteous. Had to have a few modifications made and they would discuss the issue before proceeding. Would definitely recommend this company to family and friends.

2024-06-18T17:29:00.609Z

I had a beautiful large picture window installed last May and they did an excellent job. I called yesterday with a crank handle not working well and they were here the next day and fixed it. Excellent service.

2024-05-31T13:12:36.336Z

We want to thank Mark and his employees for their insight and the quality work and products they sell. We recommend that anyone looking for windows give Mark a call. The men doing the work are very through and professional!

We recently had Window Perfections replace all of the windows in our home. The Okna product had very desirable astestic and design qualities compared to other products we looked at. There were no issues with scheduling and the installation went with no stress whatsoever. Courteous hard working professional installers. Owner Mark was also informative and available. The end result and total experience was exceptional.

2024-05-01T01:34:01.823Z

Great windows and people

2024-04-23T11:20:21.760Z

I highly recommend Window Perfections!From the consultation to the final product the service was outstanding. The workers installing were not only skilled but very accommodating ! Thank you Mark and staff ! The window looks beautiful!

2023-11-29T11:42:57.756Z

Need to replace a bunch of windows. Mark came out and explained everything. Walked us through the process and wasnt the pushy salesman you usually deal with. Crew was great and professional. Followed up afterwards to ensure everything was going well
