TESTIMONIALS
WHAT OUR CUSTOMER SAYS


Yolanda Payton
I was extremely impressed with the professionalism the works displayed during the installation and completion of the job. Even though the rain threw the scheduled completion time off it was still completed in a timely fashion. The patio has given my back yard that extra boost it needed to complete my home. It was easy to talk to the sales team and the contractors and they were willing to answer my questions. They responded without hesitation to satisfy my concerns when I had questions after the patio completed. I wasn't rushed into signing off on the project until everything was completed to my satisfaction. If you're looking to add a patio I would recommend Longhorn.
Roy Owen
We had our patio concrete coated and then had it screen enclosed. Both crews were really nice and easy to work with. Very thorough and paid attention to detail. I recommend this company.
Debra Repp
I was so concerned about how the new windows were going to replace the old ones. But when the men got here, they made me feel assured that everything was going to work out. And it did, they were great, covered everything and cleaned it all up. Then they even put my things back on the shelves. I never expected that. So don't worry they know what they're doing and do a great job. You will be happy with their work. To top it off they were friendly and respectful.
Bryan Cline
Nothing but good things to say about my experience with Longhorn about how they handled the pouring of a new outdoor patio and the enclosure of our existing covered patio. Our salesman, John, was a real delight to work with as was Ashley in the front office. They worked diligently with the city of Arlington to get the building permit approved and were able to start work almost immediately once it was. Our installer, Mike, was was very methodical and took his time to make sure everything was done right. We are extremely pleased with the quality of the work--shown in the photos--and are now waiting on another contractor to put in the wood flooring. Highly recommend this company to others seeking similar work.
Kathy Debord
I had the most pleasure experience with Longhorn. Great services, always there for appointment on time. Had to wait for my new window to get custom build , well worth it. My house looks beautiful with my new windows and I'm all winterized and the noises from out side has reduced to very little. Just the company said it would. If you looking for new windows door or siding this is the company for you. Great prices and guarantee 💯 👍 👌
Scott Burk
The windows are great they look good and they have made a big difference in noise, and temperature of our home. We live next to the highway so there is always noise after the windows we hardly notice it.
Samantha Ronin
LGH offered me Simonton windows which was the brand I wanted. Dennis came out to give me and my wife the usual window demonstration, but I wound up liking him better than the other guys since he didn't bury us in demonstrations that we already knew. Just gave us some pictures and some overall energy savings that we would get. Overall, we really liked him and at the end of the presentation, he gave me a good offer so we signed the contract right there.
Richard Garrett
I had a patio cover installed. They first said the work would begin about six weeks out but to my surprise it began three weeks out. Jim was my installer and he went above and beyond to ensure I had a strong and properly supported patio cover built. Very pleased with the result and received a very favorable and fair price.
Narvarr Gordon
Longhorn are very professional and very tidy. They installed 19 windows and 2 patio doors over the course of two days and it was a very pain free experience. These energy efficient windows and doors are already starting to show a retun on investment with our utility bill savings. We've used 100Kw less electricity this week than the previous two weeks before installation and it's actually 10° hotter this week! These windows and doors are the best investment we have made for our home to date and they also give the house more curb appeal.
Mel Perkson
Longhorn installed insulated siding on my house a couple years ago. Not only does it still look brand new, but I haven’t had any issues with frozen pipes or a cold house ever since. With all the damage people had to their homes these last couple of freezes, I feel like my siding has already paid for itself. I highly recommend!

Lois Leftwich
Longhorn designed and built a pergola over my back patio. It is beautifully done. Jim Sutton, the builder, did an incredible job. Materials and craftsmanship are both top-notch. I absolutely love it!
Pamela Craig
First of all I would like to thank Phil Ehinger for coming out to our home and going over the details of the work this company would be doing per our request. Both the Patio Cover and the Door Installation contractors were great. They were very professional and answered any questions we had regarding the work they were doing. They cleaned up after themselves and made sure our dogs would not step on anything that would hurt them. We have already had a couple of neighbors ask about your company doing windows and have referred them to give you guys a call. We will most likely call again later about doing the rest of the windows in our home. P.S. Our kids and grandkids love coming to visit us with this new outdoor patio area.
Melanie Spataro
Longhorn were wonderful! They replaced all of the windows in our house. It was a very smooth and easy process. They communicated very well.
Frankie
20+ years ago was the installation of siding and windows. To still be in business says a lot about a company. The way customers are treated is why. I have contacted Longhorn twice in that time span to have repairs done. Both times they have done fantastic work. Our siding manufacturer changed and their staff was able to track down the current owner, plus went above and beyond to match as close as could be to the original, and get the repairs accomplished.
Donald J Matthew
Longhorn did a fantastic job on our patio. From the concrete, the patio cover and the sliding patio door, their attention to details and professionalism were top notch. Their building staff can be trusted to effectively communicate with you throughout the phases and to do the job right the first time without cutting corners.
Jackie Robinius
Very professional, the windows are fantastic I can really tell a difference. The temperature in the house has maintained the desired temperature. I am looking forward to see what my electric bill will be this month I know it will be lower. The installers are very professional and did an outstanding job installing the windows. The builders of the windows did a fantastic job all the windows fit perfectly. It was so exciting to open up the window to enjoy the outside air because the window easily opened unlike my 23 year old windows where it was very difficult. I highly recommend Longhorn they are worth every penny.
Michael Smet
This is actually the second time they have worked on my home.
In 2008 they replaced 75% of the windows in my home.
Last week they came back to replace 2 more windows and to repair the brick work around the windows. They were very professional and timely. I would recommend them in a heart beat. I will use them in the future if the need arises again.
Sharon worthey
Longhorn installed new windows, put in new siding on half our house and checked the other half to make sure it was still on good shape, replaced a garage door and front door, and added a beautiful new storm door. My son has asked for their number! They even managed to retain the Tudor effect on the siding. But my favorite is definitely the new windows! Love that we can now enjoy a breeze without worrying about pets tearing up the screens since we can now open the windows from the top! SO HAPPY with the job they did. Thank you Longhorn!
Sharolyn LePage
Great experience. We had all of our windows replaced. They finished ahead of schedule and communicated well. We can already tell a difference in the temperature inside of the house.
Donna Love
Longhorn installed 9 windows a few years back and now we've had them back to do our siding and WOW, just WOW, our house looks awesome! They have been honest with their estimates, kept us informed on their schedules, rain delay, and completions. Clean polite workers. The windows are wonderful! Changed the house completely. Saved on July & Aug bills and this winter has been so much warmer in the house!! The siding has really improved the look of the house! I am just shocked at how nice it all looks and perfectly fits together at every corner, overhang, and porch. Would hire them again and again.
