STAY AWAY FROM THESE GUYS AND IGNORE ANY BIDS EVEN IF THEY ARE THE CHEAPEST.. Not sure why other users who only got quotes are leaving reviews. These guys are terrible in every aspect of a business. The windows and labor appeared good but the company is run by inept thieves. We had every window ~36 replaced, two doors and insulation for the attic. Sales presentation and everything up front was great. Once they had my deposit issues started. The back office people failed to communicate with the installer when the windows arrived and we missed our install window that was initially given. The install crew did everything possible to meet the second window (we had other projects also going on) only to find that the operations team failed to order several of the windows so the guys had to come back again from Houston. Finally the doors arrived and operations ordered the wrong doors. Another couple weeks go by and the missing windows arrive, they get installed and windows are done. The doors arrive and they get installed but the install crew finds that the ops team now failed to order the door trim in the correct color. At this point I reach out to the owne who is a lying POS and didn't follow through on any of his promises once he had my money. Three more weeks go by and the correct doors finally arrive and are installed. At this point they demanded payment in full despite the insulation not being completed because the contract had a clause that payment is due when 90% of work is completed. So we pay in full and the insulation is scheduled. We were out of the house for the insulation due to having no working bathrooms and it's "completed" with us not there. We later came to discover that these guys rented a machine from Home Depot and had someone who didn't know what they were doing blow in insulation. The levels were not even and there were even huge bare spots and they only did one section of the attic. After weeks of calls to Tim Nash and his boss they finally agreed to fix the issues but only addressed half of the attic and did not do the separate attic. To date they have repeatedly agreed to fix things but now have stopped answering calls. We will likely have to take legal action at this point. Ignore the positive reviews on this site from people who have gotten quotes. I'll be the first to tell you their sales pitch was great but not a day goes by that I don't regret going with them over one of my other bids. read more

We called Allied Siding & Windows for an in-home estimate after seeing them on Good Morning Texas. We live north of the metroplex (near Gainesville, by the Oklahoma border) so I was not sure if they would service our area. I was pleasantly surprised to find out that they do work at Lake Kiowa! Our salesman, Jay Weda, came to our home at a time that was convenient to us. He presented me with an IPad to watch a short video about Allied. It was informative and afterwards, we also got a paperback book about home remodeling. The same night Mr. Weda came to our home, we signed a contract for the replacement of our 25 year old siding. It's not an exciting purchase but we knew our house needed it. We had original aluminum siding that had been dented several times through the years with both golf balls and hail. We've always suspected that we didn't have as good of insulation as we could have. We had not idea of the status of the framing that would be exposed through this process. We weren't too worried as Allied did have a contingency set aside for any repairs that needed to be made to our structure. Over the last week and a half, we have had a crew of approximately 5 taking down our old siding and replacing it with James Hardie siding. They have been careful to do one section at a time before moving on to new sections. We had a couple of days of rain and before the team left, they made sure to have any uncompleted are covered so that there was no chance of damage. They cleaned their area every afternoon and kept their trailer in one section of the yard so our home wasn't completely disrupted. After 8 full days of work, all of our old siding has been hauled away and our house looks brand new! We were so pleased with the workmanship and the product that we have just ordered new gutters as well! read more

I purchased nine windows from Allied Windows & Siding. I just wanted to let everyone know how extremely satisfied I am with not only the windows, but also the courteous and professional staff that came out and put them in. They arrived thirty minutes early and did not stop until all the windows were installed. Ryan demonstrated all the operating features and answered any questions I had pertaining to them. I'd also at this time, hope that Ms.Freeman, will accept my sincere apology since our last conversation, it has been a hectic week for me, with a death in my family. It doesn't excuse my poor behavior, but maybe explains it a little more clearly. Mr. Courtright, I implore you, please do not hold the difficulty involved with this job against Rick, the project leader. I believe it was just a series of miscommunications and I personally hold no ill will towards him or anyone else associated with your company. I plan to share my positive experience and would recommend your company to all my family and friends. I also plan to re-post positive follow-up comments on YELP, it is the least I can do rectify the situation. Once again I would like to thank everyone at Allied Windows & Siding for a job very well done and with customer service of this caliber, I am confident that your company will remain prosperous for decades to come, take care. read more

Our home, built in 1976, still had the original windows and rotting siding along the back and side of the house and garage exterior walls. It was long past the time for change. Luckily, we heard about Allied Siding and Windows and have been more than satisfied with both the quality of the work and the materials used. Rick, our sales rep, came out to our house and spent several hours looking things over and making recommendations. Rick's professionalism certainly played a big part in our decision to use this company. We ended up replacing the rotted siding with Hardie siding and trim, both of which were painted to match our house colors, and the colors matched perfectly. At the same time, the workmen checked our insulation and looked for minor structural problems, and removed and replaced the gutter. The work was completed well within the quoted timeframe (we had lots of conversations with Rick about times for order placement, materials arrival, workmen scheduling, etc.). Rick also visited our home several times when the work was being done, and checked things out when it was finished. All trash, etc. was cleaned up and hauled off. We highly recommend Allied for this type of work. We couldn't be happier with the way it all turned out! read more

Had 10 windows replaced by 8 in April of 2018. The quality of the windows are fine. Our problem is with the after the service after the sale. Considering the weather here in Houston, we don't open the windows too often. When we did finally open the windows we discovered one window would not open all the way. When I called Allied, as soon as the found out I needed a service call, the lady immediately changed her tone on the phone and directed me to the website to fill out a form and made it very clear there would be a $95.00 service call fee. The windows are less than a year old and under full warranty. They called once and we haven't heard back. Window still won't open. So...after spending over $6,000 for windows, Allied has dropped the ball on any type of continuing Customer Service. What I am trying to say is they don't back their work. read more

Allied Windows and Siding. If you want reliability and good pricing you should start looking at another company. They are about 20% higher for the same widows and they make promises they cannot keep. I should have shopped around but I trusted them because Nolan Ryan did. What a joke! They said the windows would be installed in 6-8 weeks. It took them 12 weeks to get the windows in and then they didn't even have all of the parts to properly install the windows!! Then they banged up my newly painted walls during install and made no resolution to fix them. Update to posting. Since the first review and after paying off the windows in full the owner of the company is now trying to charge me more money. EVEN THOUGH I HAVE A 'PAID IN FULL' letter. Wow!! Be careful of these guys. Not sure what type of tricks they are up to. read more

We had all of the windows on the back of our house and patio doors upgraded and replaced. WOW! The results are even BETTER than we had imagined. Our home feels like a new house now. Allied Siding & Windows is by far the best window/door company we've ever used. We've done many remodel and replacement projects in the past but have never had such professional and quality results like this. Leonard, the owner, is personally available to ensure that everything goes according to plan and is reachable by cell phone anytime. Ed was the professional installer and he is a superstar! He made sure that every little detail was done meticulously and went above and beyond when it came to everything being just right. We can't say enough great things about Allied.....we'll never use another company for windows, doors, and siding! read more

We had 19 Simonton Generations replacement windows and James Hardie siding done on our home of 22 years, by Allied Siding & Windows, here in NW Houston (Tomball area), in the summer of 2013. It has been almost 3 years and it all still looks brand new - inside and out! The workmanship and attention to detail is why we chose Allied in the first place. I cannot believe how quiet the argon gas-filled windows make our house; besides keeping it cooler in the summer! Our dogs cannot even hear the fireworks on the 4th of July any more!! We had someone stop by our house just last month to ask us about our our siding and trim colors and asked if they could "look around" and take some pictures!! Quality, workmanship, and value. We continue to enjoy our choice from 3 years ago - our choice was Allied Siding & Windows !! read more

i have small children at home and even though i knew the end results would be great, i was nervous about the dust and dirt that replacing windows would leave behind. i had heard a lot about the work ethic and cleanliness of the allied siding and windows people and was very impressed to learn that it's true! they were very careful moving my furniture, preparing their work area and they cleaned up every day before they left my house. we will definitely keep using allied siding and windows for future projects in our home! read more

This is so unbelievable! All it took was one phone call and my entire home changed. My home was never looked so great and the people at Allied were just so sweet and courteous. I would have never thought get siding and windows was so easy and hassle free. The crew was also kid friendly. My daughter would always talk to them and distract them but the always remained nice and positive around her. The most amazing part was how clean they are!!!! EVERYDAY they cleaned and removed debri. read more

I have worked with Lenard and Darryn from Allied Siding and Windows on many occasions over the years and have found them to be honest and reputable. The sales staff at Allied are knowledgeable and helpful and represent the company professionally. there product line including Hardie siding and Simonton windows, which I had installed on my houses, are top notch quality. I would recommend Allied to anyone in need of siding, roofing, or windows. read more

Allied has been around forever. I've known the Sales Manger Darryn Finn for over 15 years- Very conscientious guy. They don't try to do everything for everybody. They focus on the exterior of the home- Hardie Plank siding, Windows, doors, roofs, patios, etc.. They do what they do, and they do it well. And they only use named brand products by companies that stand behind their products- not the generic stuff like a lot of companies now days. read more

Allied Siding is the best. They did fantastic job on the siding and paint. There was a little issue with the gutters, but they made good on it after over a year and fixed a minor problem under warranty. When I complained about this I got a call from Mr. Leonard Courtwright, the owner , and he promptly set things in motion to have it repaired. They are truly one of the most customer focussed companies I have done business with. read more

We just had Allied come back to replace our windows too! They replaced our original wood windows with new energy-efficient vinyl Simonton windows. Not the cheapest, but I did my research and these windows pay for themselves in energy savings. My wife and I are very impressed with the installation and would hire them again without question. Highly recommended! read more

Honestly I was not looking forward to have all the windows in my house replaced. I hate contractors! Allied was so different and made everything so easy and quick. Not to mention how clean and friendly they are. They do not fall under the typical contractor stereotype! I had my feet up the whole time. Not once did I have a complaint. Thanks guys! read more
