TRUSTED BY THOUSANDS OF DIY HOMEOWNERS
Last updated: April 2026
Buying window film is a meaningful investment in your home. Before you commit, you want to know: Does it actually block heat? Is it possible to install yourself? Is the company easy to work with if something goes wrong? The best way to answer those questions isn’t from a brand — it’s from homeowners who’ve already been through it.
We’ve gathered verified customer reviews from our website and organized them into three categories – Concord Window Film Reviews for: Film Performance, Installation, and Customer Service. These are real people, real projects, and real results. We haven’t cherry-picked — you’ll find honest feedback alongside the reviews, because that’s how trust works.
Concord Window Film is rated 4.85 out of 5 stars across hundreds of verified customer reviews. Our flagship product, the ComforTech™ Ceramic Series, is a professional-grade solar control film available in five shades (45, 35, 25, 15, and 05 VLT) — the same film used by professional installers, now available direct to homeowners in pre-cut and custom-cut kits.
What do customers actually notice after the film goes up? Heat rejection, glare reduction, privacy, and clarity are the most common themes. Here’s what they said in their Concord Window Film Reviews about film performance:
★★★★★ Mark H. | ComforTech 15, Custom Cut Kit “Reduced heat in our Great room substantially. We went with ComforTech 15, and it was the right choice. Still lets in plenty of light, even on cloudy days. But glare is reduced making the room more pleasant, as well as the reduced temperature of the room. We’ll be installing more Concord film on our south windows in the future!” |
★★★★★ John S. | ComforTech 35 “This film is awesome! Our A/C was overwhelmed by our skylights for years but not anymore with this!” |
★★★★★ James A. | ComforTech 25 “ComforTech 25 Ceramic Window film has done a wonderful job of reducing the heat transfer into my home through our south facing storm door glass. The main entry door used to get so hot you could not keep your hand on its surface. That is no longer an issue.” |
★★★★★ Anonymous | ComforTech 35 “Nice film and easy to install. Made a NOTICEABLE difference when applied to our west-facing windows. Already benefiting from reduced AC energy costs! Ordering more soon.” |
★★★★★ Danny Leonard | ComforTech 35 “The perfect tint 35 to let light in while blocking heat & UV. I have the right 2 windows done. When the morning sun is shining in, we can really tell a difference between the completed windows & the left 2 windows.” |
★★★★★ Dot V. | ComforTech 15 Storm Door Kit “Makes a huge difference with direct afternoon sun. You can see out beautifully but it’s not nearly as hot as it was. We did the arches above the doors.” |
★★★★★ Roger P. | ComforTech 35 “I am truly impressed with how the window film reduced the amount of heat that was coming into my house (I live in Florida). The 35% was exactly what I was looking for as it is slightly darker from the outside and not so reflective (mirror look) as a commercial building.” |
★★★★★ Brian M. | ComforTech 45 “The product is excellent. It’s a bit darker than I expected but it doesn’t diminish the view of the outside. Makes a huge difference in deflecting solar heat. So much more comfortable in that room now!” |
★★★★★ Brian P. | ComforTech 45 “Installation went very well in part due to the quality of the installation kit. The film is a little bit darker than expected, but it drastically cut the solar load from our south facing bay window. Would recommend.” |
★★★★★ Michael H. | ComforTech 25, Custom Cut Kit “Exceptionally easy installation and looks beautiful. Live in Florida and went with 25. We’re in an east/west house so we get morning and afternoon sun. Helps tremendously to keep the glare down and control the heat.” |
★★★★★ Jeanna | ComforTech 25 “I questioned whether installation would be effortless, and I am delighted with the outcome. We sought to mitigate the heat within our residence. The afternoon heat permeates our house, and the Florida sun is unyielding. Very pleased with the results.” |
★★★★★ Kevin M. | ComforTech 35 “We applied it to 50 year old double pane casement bay window that had no existing tint or solar blocking properties. It has really reduced glare and heating in the room. Wish we would have done it sooner.” |
★★★★★ mark n. | ComforTech 15 Storm Door Kit “The film really cut down on the heat buildup between the storm door and the front door and added a level of privacy when I want to leave my front door open. Glad I did it and Concord made it a breeze.” |
★★★★★ Mark (Professional Photographer) | ComforTech 45 “Love this window film! There was a cheaper big-box brand that was readily available but there are some characteristics that are worth paying the premium. All specs aside, the quality of light that enters the home is very natural and beautiful, unlike other cheaper films that ‘contaminate’ the light with an unnatural color cast.” |
★★★★★ Rick | ComforTech 45, Custom Cut Kit “Film shipped quick and window tint 45 looks great on these east windows. Just the right tint without making the room darker late in the day.” |
★★★★★ Mary R. | ComforTech 35 “High quality film really helped with glare and heat on my west-facing storm door. I would recommend Concord to anyone looking for DIY window film.” |
★★★★★ Sheri | ComforTech 15, Custom Cut Kit “We’re THRILLED with the outstanding ambience, privacy, and glare control ComforTech 15 offers — it’s truly a commercial-grade DIY product that will wow you with its ease of installation and its exceptionally professional performance! By day, the ComforTech 15 cuts glare dramatically and gives a mildly shaded appearance — light gray, not a ‘dark sunglasses’ look — and we now have the substantial added privacy we desperately needed. Our nighttime results are just as amazing. We leave our interior lights relatively dim in the evening, and with the film in place, we’ve been able to change the porch light to 80% brightness, allowing us to achieve fantastic nighttime privacy as well.” |
★★★★★ Donald Kalil | ComforTech 25 “Keeps our greenhouse from overheating. Great product.” |
★★★★★ Richard F. | Silver 15 Reflective Window Film “Best window film I have used so far and works as advertised.” |
★★★★☆ TIM | Silver 15 Reflective Window Film “You can see blinds through the film from the street and you can see in the house if you get close, especially if there are other windows in the house that are in the line of sight.” Editor’s Note: This is an accurate observation about how privacy films work. All transparent privacy films rely on a brightness difference between outside and inside to create a mirror effect — the brighter it is outside relative to inside, the stronger the privacy. Interior light sources can reduce this effect. ComforTech 25, 15, and 05 provide the strongest daytime privacy. Our sample kit is the best way to test shades in your own conditions before ordering. |
★★★★★ Thomas | ComforTech 15, Custom Cut Kit “Easy to use. Installed 15% which does a great job of heat reduction but also a significant loss of room lighting. Did not install film in adjoining room because of the darkening effect.” Editor’s Note: Lighter shades like ComforTech 25 or 35 may be a better fit for rooms where natural light is a priority. Our sample kit lets you compare shades in your own space before committing. |
★★★★★ Larry | 2 Mil Clear UV Window Film “UV film stopped UV light from entering our windows. I can’t see any difference in clarity through the film. Easy to install.” |
One of the most common questions we hear is: “Can I really do this myself?” The answer, according to our customers, is a resounding yes — with a few tips. Here’s what customers said in their Concord Window Film reviews about installation:
★★★★★ Naomi | ComforTech 25 + Custom Cut Kits “The experience was seamless from start to finish. The tint was cut to the size I requested, with enough overhang that made trimming easy. What really stood out were the instructions — they were incredibly clear and easy to follow, making the DIY installation a breeze even for a beginner. The final result looks absolutely professional and has significantly upgraded the look of my home. I completed 8 bay windows, two patio doors, two screen doors, and a large foyer window.” |
★★★★★ Sandra A. | ComforTech 35 “We tinted 43 panes of glass in our home and saved a lot of money doing it ourselves. The process isn’t super difficult, but we strongly recommend watching some installation videos from Concord and professional installers of all brands to help with tips and tricks. The installation kit is a must, in my opinion!” |
★★★★★ Jerry B. | ComforTech 35 “Best product on the market. Easy to follow instructions and the results are better than expected. This was my first attempt at window tinting and my project was larger than most — 2 sliding doors (1) 91’’ x 57’’ and (2) 91’’ x 45’’. I was able to do it myself and the sliding doors look great. Don’t be afraid to do it yourself.” |
★★★★★ Joseph E. | ComforTech 35 “This is excellent quality film. I’ve used Gila in the past and it rips or tears easily — this stuff does not and should last many years. It’s easy to install. I had 17 windows and a patio door to do so I bought two install kits, which was a smart move. The hardest part is trimming the film but once you’ve got that down it’s easy to do and you get in a groove.” |
★★★★★ Jerry (Age 78) | ComforTech 15, Custom Cut Kit “I was a little worried to take on such a project for I’m 78 years old. I spoke to Kristen, who assured me that I should be able to install the film. After I got over the fear of ruining the film, I started. The instructions were very helpful. I completed two sliding doors in about an hour, not one bubble and it looks great. I have since ordered for two more doors and some windows. I’m sold on the company.” |
★★★★★ Thomas | ComforTech 25 “Shipping and delivery were very fast. The product was easy to use as the pre-sized pieces worked perfectly. The tabs allowing easy separation of the protective film were very helpful. The directions that came with the film were so clear and the videos on the website were a great visual. Saved a lot of money vs paying to have the windows done!” |
★★★★★ Geoff | ComforTech 35 “Successfully applied tinting. 1st timers. Prepared carefully. No bubbles. Looks great. Did not expect to achieve near flawless results. Quality material.” |
★★★★★ Toni R. | ComforTech 25, Custom Cut Kit “The film went up without a problem. The best results were the days when it was rainy and the window panes were cold — it lengthened the time so the solution I sprayed didn’t dry, and thus, I could move the film and position it well. It came out nicely.” |
★★★★★ Mark | ComforTech 25, Custom Cut Kit “This is a great solution to our situation. We get sun from sunrise to about 2:00 p.m. The glare and heat were making it impossible to have the drapes open. The film has made it much easier to enjoy some daylight. I highly recommend watching the video as you are installing.” |
★★★★★ Denise Midyette | ComforTech 25 “Great customer service. Easy to work with the film. I’m 73 and this was simple for me to do. Regular windows and doors would probably be much simpler.” |
★★★★★ Brian | ComforTech 15 Storm Door Kit “I love the film. It was not too bad to install. A little easier on double hung versus casement. They stand behind their product and will support you if needed.” |
★★★★★ Jeffrey T. | ComforTech 15 Storm Door Kit “Films are excellent. Be careful with trimming the film to the window to get as tight a fit to the window edges as possible. On smaller windows I precut the film to the window dimensions rather than trimming them in place and the fit was excellent.” |
★★★★★ Terri P. | ComforTech 25 “If doing a glass storm door kit and yours has the screen away, save the ‘peel here’ tabs for when you do the bottom glass to help get the liner to separate easier. Good product.” |
★★★★★ Albert R. | Installation Tool Kit “Was skeptical about ordering an installation kit. However, after using it, I would highly recommend for anyone self-installing film. The squeegee and razor scraper are high quality tools that ensure a good film installation.” |
★★★★★ James A. | Installation Tool Kit “The tool kit was worth the price in aiding the installation. The only part I didn’t use was the plastic trim knife — I have a Dewalt blade knife that is much more sturdy.” |
★★★★☆ Anonymous | Large Door Installation “The installation for a large door is more complicated than the instructions explain. A video showing installation on a large door would be helpful. It’s a very different experience from the small windows that are in the tutorials.” Editor’s Note: Great feedback. For large sliding doors or full-view storm doors, we recommend having a second person to help with positioning and trimming. Reach out to us directly if you have a specific project and want tips before you start. |
★★★★★ michael Bushnell | 4 MIL Safety Film Kit “It was critical to wet the back side of the foil as well as the window. I missed that in the instructions at first. Really worked.” |
★★★★★ Carol Longoria | 4 MIL Safety Film Kit “Quick delivery even during winter storm. Videos allowed for easy installation.” |
★★★☆☆ Tammy | 4 MIL Safety Film Kit “We struggled a bit with the application on a small bathroom window. The amount of excess to leave (one inch) was too much on such a small window, especially given the thickness of the 4 mil film. The second half of the window went slightly better by not leaving as much excess.” Editor’s Note: Good practical tip — on very small windows with 4 MIL film, reducing the excess trim allowance slightly makes the trimming step more manageable. We’ve updated our guidance to reflect this. |

★★★★★ Sheri | ComforTech 15, Custom Cut Kit “When we landed on Concord’s website, Kristen offered immediate support, providing candid answers to a range of questions about our specific applications (shade/sun ratios, use on tempered glass, night visibility, etc.). We then purchased the sample kit and moved into the prep phase.” |
★★★★★ Michael Feinman | ComforTech 35 “Great customer service makes a happy customer. I messaged Kristen with an issue I caused myself and her quick response was the best. I went with ComforTech 35 for my black front door, not realizing ComforTech 15 would reduce the heat level to where I needed it. Kristen sent me out a sample package to help me determine the film I needed and within days of messaging, with no charge, she sent out replacement film. I highly recommend Concord Window Film — quality product and customer service.” |
★★★★★ Greg Schmidt | ComforTech, Custom Cut Kit “Kristen was absolutely amazing to work with. She made the whole process from start to finish enjoyable.” |

★★★★★ james rolland | ComforTech 15 “Kristin was an absolute pleasure to work with every step of the way. The product is great!” |
★★★★★ Stephanie W. | ComforTech, Custom Cut Kit “This company is wonderful. I ordered the wrong roll of film, but they gave me a refund for the unused portion, which I wasn’t expecting. Then I loved it so much I ordered another individual sheet.” |
★★★★★ Robert Jayne | ComforTech, Custom Cut Kit “Excellent service and extremely happy with the film. Easy installation. I would recommend you to anyone I know who is looking for window film!” |
★★★★★ Paul | ComforTech 25 “Working with Concord was great. Excellent advice, delivery, instructions to install and it works. Thank you.” |

★★★★★ Kim Giddens | 4 MIL Safety Film Kit “Great customer service!!! I will be using them again.” |
★★★★★ Roy Juneau | 4 MIL Safety Film Kit “Perfect! The packaging is incredible — so much care. We ordered the clear to bring a bathroom window up to code. When we received the order, the ANSI stickers were missing. One phone call and she sent them UPS to us.” |
★★★★★ Marianne | ComforTech, Custom Cut Kit “Excellent customer service (thanks, Kristen!). Custom-cut pieces made installation a breeze, and the video instructions were clear and easy to follow. Highly recommend!” |
★★★★★ Anonymous | ComforTech 25 “All of my pre-order questions were quickly answered and that service before the sale was very much appreciated.” |
★★★★★ Anonymous | ComforTech “Your customer service was delightful. I would definitely use your product again, as well as refer you to everyone I know.” |
★★★★★ Natalie | ComforTech, Custom Cut Kit “Delivered quickly. Easy to install. Needed to contact customer service for a delivery question and they were very pleasant to work with. Will order from them again.” |
★★★★★ Keith D. | ComforTech 15 “Extremely nice presentation. The film and the install kit were premium quality products. I felt as if I had received a package from the Marriott. Thank you.” |
