From Steve Little - Wapakoneta, OH

Keep doing what you're doing.  Perfect!

From Mary & Dave Fisher - Cecil, OH

There is no way what you do can be improved!  Matt and Mike were professional and talented in their work.  I love my new window.  Thank you!

From Norla Strasbaugh - Kenton, OH

Thank you again to the installation guys.  They were conscientious workers, answered my questions, and cleaned up so well you never would have known they were here!

From Charlotte Williams - Wapakoneta, OH

I just wanted to let you know how pleased we were with the recent installation of the new windows for our business building. Your crew was working with a one-hundred-year-old building; of course, nothing wanted to fit right. Your crew worked until they were satisfied with the fit. Lastly, your cleanup was spectacular... you wouldn't know that they were there! Thanks for a well-done job.

From Dixie Alexander

How do you improve on perfection?

From Ann Rice - Lima, OH

Came home to find my new doors installed - they were able to schedule us a couple of days early and put two crews to work, so everything was done, from arrival to clean up and gone, in less than 8 hours. The 3 new doors look great, and more importantly, immediately made the house more comfortable and secure.

From Patricia Freeman - Lima, OH

Thermal Gard is the best around! The last installation was on S. Baxter. My tenant was amazed at the knowledge and professionalism of the installation crew, I told him they are the best. He agrees!

From Ralph & Deb Schaad - Lima, OH

From the first call to completion this was a top-notch project. Austin was knowledgeable and Mike and Matt were neat, efficient and courteous. I can't brag enough about the experience.

From Glenn - St. Mary's, OH

We're very happy with the quality of our new windows and the professionalism of the installation crew. We had 10 windows installed and the project was finished and cleaned up in one day. We have already seen savings on our heating and cooling bills.

From Barb - Bluffton, OH

Thanks so much for the beautiful windows. It makes my home so much cheerier! Thanks again.

From Andrea Friemoth - Delphos

I cannot say enough good things about Thermal Gard. We recently had two new doors installed and new windows a few years back. The quality is outstanding….our heating/cooling bills have gone down and the house is quieter. The employees are very friendly and professional as well. Thank you for the great product and installation.

From Michelle Risner - Mount Cory

We had Thermal Gard installed at our first house 30 years ago and have installed them in our second house over the last 10 years. Just installed two bays windows and had an issue with the color of the trim. Thermal Gard went above and beyond to correct the problem and make us happy. Would use them again!

From Jerry & Sharon Ault - Kenton

Great job! Love the windows!

From Barb Barnett - Bluffton

Very much well pleased.

From Janet Parcell - Lima

Thermal Gard has installed for us before. We have been happy and satisfied with each time. Thank you.

From Nikki & Morris Music - Lima, OH

From the beginning with sales, to the installation and clean up, Thermal Gard and employees were knowledgeable, thorough, and clean. Best experience we could have had!

From Emily & Joel Hamric

We were absolutely thrilled with every aspect of your service. Our windows are beautiful and are already helping our heating bill.

From Audrey McCune

Very professional from the first time Paul came out to the finished job. Very nice and conscious of health and safety issues. Thanks!

From Thomas Binkley

I had to leave for work before the men had completed the job so I left with the good feeling that the men were going to leave the place the way they always have, cleaned, locked up and most of all I went to work knowing I could trust them and that means a lot to me. It's like they say, 'It don't get any better than this.' Thanks Thermal Gard.

From David Laman

I have and will tell people how happy I am with the product and service you have given me. Thank you!

From Audree Hinegardner

Austin Sutton was an awesome sales representative. Thank you. We love our windows.

From Scott Miller

We have gotten just one window replaced, but we will get the rest replaced by you all. We love our new picture window (4 casements). Could not be more happy with the whole process.

From Patricia Freeman

Dudley is adorable! I have always been very satisfied with Thermal Gard. The quality of their work is superior. This company is a real asset to Lima and the area.

From Julie Geesy - Lima, Ohio

Awesome job! Got my door weeks earlier than expected. Great job installing the door. Salesman was very knowledgeable and polite. Would recommend Thermal Gard!

From Becky Bowsher - Spencerville, Ohio

Excellent job from start to finish. Salesman Paul Illig was very professional. Amazing price on new windows for my house. Installers were courteous and knew very well how to do their job. I love my new windows! Thank you all at Thermal Gard.

From Lynette Lewis - Elida, OH

The improvement is incredible. We have a large decorative window that we love for the view and sunlight. We needed something to help with heat in winter and cooling in the summer. Thermal Gard had the answer and added custom storm windows. They match our siding perfectly and really solved our issue. The installers were friendly and did a fine job. They even cleaned the windows when they finished. In the future Thermal Gard will be the company I call for any window or door improvement. Thank You!

From Zola Dulle - Columbus Grove, OH

I just love my new windows and doors. The difference is incredible. My house is air tight and my furnace hardly ever runs. My front door and storm door were just installed today and I just sit and stare at them because they look so nice. Now I'm going to do my garage. I have four windows and a side door that I am replacing. I am just thrilled.

From Patty Cassell - Lima, OH

Paul Illig, sales manager, spent a lot of time at my condo carefully assessing the condition of each of my 21 windows. He coached me on how to get my windows fixed that were bought by a previous owner from a competitor. Since I only had one window to be replaced, the office staff fit me in between appointments. The installers were prompt, professional, courteous, and efficient. I like my new easy to clean window.

From Randy & Lori Rollins - Lima, Ohio

2019 late summer, we decided to put in windows using Thermal Gard. This was probably the best decision that we have made. We compared pricing throughout the surrounding area, and even though Thermal Gard was a little higher, we felt their sales people were the nicest. When the windows were installed, the workers were the most professional I have ever seen. They worked together like a well oiled machine. We even had a manufacture problem and they came out with different workers to repair the issue. Those workers were also very professional. We are now 6 months into having them, and the savings on the heating/cooling of our home is unbelievable. During the wind storms we had recently, we did not hear the wind at all. We also live on a corner in Lima that gets 10,000 cars a day passing by, but we feel like we live in a quiet neighborhood now. Just so you know, we replaced 12 windows with triple pane glass and we couldn't have asked for anything better in quality of the product, the service and the workmanship. Thank you Thermal Gard!

From Tim & Marilyn Kuenning - New Bremen, Ohio

Very happy with our new windows. The 2 installers were very polite and professional. Can't believe they did the job so quickly. I will definitely recommend Thermal Gard to others. We are so happy that we are getting all of the remaining windows replaced in January 2020!

From Stanley Kollars - Lima, Ohio

A very good company. The installers were very kind and courteous.

From Robert Kiss - Walbridge, Ohio

The Thermal Gard installers worked for 2 days in the wintery cold and wind to complete my project. I have big windows and lots of them. The installers were pleasant and answered any questions I had about the windows. Upon completion, I immediately noticed my home was warmer with no drafts. The outside looks cleaner and newer. Since my curtains no longer move in the wind I am looking forward to my lower gas bills. Thank You, Thermal Gard!

From Nina Gibson - Elida, Ohio

We are very satisfied with our new windows. Your services from start to finish were quite professional and satisfactory.

From Tammy Quintero - Lima, Ohio

The installers were very efficient. They got to work as soon as they got here, took a short lunch and continued until the job was finished. We were very pleased with the results. The neighbors also commented on how efficient they were. Thank you so much!

From Andy Bauman - Lima, Ohio

I love the new look of our new windows. Hopefully, it will also save us money this winter. Your crew did a wonderful job. Thank You!

From Jack & Ruth Smith - Wapakoneta, Ohio

Thank you VERY much for the "door prize" 🙂 We are so thrilled that Jack's name was chosen. And, even more, thrilled that it is such a fantastic door! I have to hear every night since August 9th that Jack can't believe how wonderful your door is!

From Mr. & Mrs. Frazier - Maplewood, Ohio

Thermal Gard, Thank You so much for the windows! We really appreciate your installers-they are professional in every way and do a great job. We would definitely recommend your company.

From Richard Nichols - Lima, Ohio

Just a quick "thank you" for the excellent job your company did of installing my three new windows. The two guys were prompt, courteous, and did a neat job of installation. The windows look great on both the inside and the outside. I would definitely recommend Thermal Gard to anyone!

From Darryl & Deb Barhorst - Ada, Ohio

The window crew should be held in high regard. They were on-time, professional, very skilled, and went above and beyond the job. I will highly recommend Thermal Gard to all my friends and family. Thank you for a job well done.

From Melva Robinson - Wapakoneta, Ohio

Dear Thermal Gard, I would like to tell you how pleased I am with my new Thermal Gard windows.

My home is much quieter and the windows glide open and shut so easily. The installers were very professional, quick, and efficient. I am also very impressed by the job done on my garage window.

The installers made a "silk purse from a sow's ear!" I cried when I saw how wonderful it was. Thank you for a job well done!
