“Our home still had the original cedar wood siding from 1987. It was faded, rotting in places, pulling away, and honestly just looked tired and sad. We got quotes from two major siding contractors in Austin, and Allied Siding not only came in with the best price, they also gave us a timeline that was dramatically faster than the competition. The siding crew made quick work of removing the old siding and repairing any problem areas they found along the way. They sealed the windows, installed a new moisture barrier, and had the entire home re-sided in just three days. The transformation was remarkable. Our house went from a dated 1980s look to something that feels fresh, clean, and worthy of 2026. After a short weather delay, the paint crew came in and finished the entire job in another four days. In total, the project took only nine days, and that included two door replacements, and all exterior doors and the garage doors being included in the paint job. One of the other local companies we considered was about $10,000 more and estimated the project would take around four weeks. We are extremely glad we chose Allied Siding instead. Diego, our on-site foreman, did an outstanding jo”

“William did an excellent job on our siding. He double checked on things to make sure we got what we wanted, they left the grounds clean and swept, communicated well, and he even went above and beyond by putting the new lighting that we have been meaning to update in when they put the lights back on. I love the new look and now we have to update the garage, front door, and landscaping to match!”

“Siding replacement and paint work, very professional. They worked really hard and did a great job on my house. It looks like a new build! William and Tim kept us informed the whole project. So glad we got this done with a company that knows what they are doing.”

“I am so happy that I chose Allied Siding & Windows to replace my old windows and siding almost 3 years ago. I only recently created a Google account, and I wish I could have shared this review much earlier because this company truly deserves it. Back when I was looking for the right company, I heard good things about Allied from a couple of friends and even a neighbor. After comparing products and prices with several companies, Allied was clearly the best match for what I needed — and at a much better price. I’m very glad I met Tim, the sales representative. He took his time to show me all the window and siding options and helped me choose what would fit my home best. When the job was done, my home looked completely refreshed and beautiful — and it still looks great today. Recently, one of my window panes broke for a reason I still don’t know. I called Allied for help, and I spoke with a very kind lady (I’m sorry I forgot her name). She was so nice and explained that I didn’t have to pay for new glass — it was still under warranty. She then connected me with their warranty department. From there, everything continued to be a wonderful experience. I was extremely impressed when I”

“We used Allied to replace our windows and siding (hardiplank). We were beyond satisfied with the outcome. Edgar did a wonderful job with our windows. Diego always kept us in the loop on the status of our house. Diego and his crew were very respectful and very hard workers. We continue to have people stop by and tell us that the house looks amazing. From, An extremely satisfied customer”

“Great experience from beginning to end! Salesperson, Tim, was always friendly and extremely knowledgeable about his product AND that of his competition. Edgar and his team did the installation and we couldn't be happier with his efficiency and professionalism! I can't think of a single thing that I would have liked to have been done differently. HIGHLY recommend Allied for windows!”

“We are completely satisfied with the work completed by Allied Windows and Siding. Our crew chief, Miguel Angel Martinez, was professional and kept us informed every step along the way.”

“Or experience using Allied for new windows was excellent! From the no-pressure sales from Tim, consistent updates from Sammy, to the removal and installation by Edgar, everything was handled very professionally. Edgar and his team did a wonderful job being on time, polite, and thorough. Our new windows are gorgeous! We will definitely be recommending Allied to friends and neighbors who are looking for windows.”

“My wife and I can’t recommend Allied enough for a Hardie plank installation. Diego and his crew were spectacular to work with too and still can’t believe the quality of work and how short the turnaround was.”

“My installation pitch went as expected and was much easier than the 2 hour one I received from another company. It probably lasted no more than 30-40 minutes, which they were able to provide me an estimate with out measuring my windows. They scheduled someone to come out to measure but this ended up being rescheduled 3 times. First no one showed up, and I called. Second they rescheduled but had a last minute emergency and 3rd they brought the actual installer out to measure. It took about 3 months for the windows to arrive which was normal, but they had 2 wrong sized windows. I’m not sure if they were measured wrong or if the manufacturer messed up there. One of the windows is an arched window which is clearly not the same window as the original one. None the less, I wasn’t told this until the very end of the install that two of them will need to be reordered. We were given a day they’d start install but and said they’d arrive at 7:30am, but when 10:30am came around, I finally called to ask where they were. The installer said they were running late and would arrive after lunch, due to this, they’d have to finish the days work pretty late but didn’t give a time. Unfortunately we m”

“How I wish I could go back in time and use literally ANY other company to replace my windows. Allied continues to be a headache for me a year and a half after installation. It began when a team came out and mismeasured each of my windows, causing them to have to spend two full days recutting the spaces to make the windows fit (leaving behind the damage in the first two photos. And before they come back and comment with some excuse, that damage was NEVER fixed, that's how they left the finished project to this day.) In addition, I, a 24 year old girl who doesn't work on windows for a living, sent in some sketches to give them rough measurements and instead of looking at literally any other unit in my complex or following instructions to match based on the HOA, they went ahead and ordered everything based on my rough sketches. So now, I'm left with bedroom windows that don't match any of the units because they don't have grids on them. I've since had three companies come out to give me estimates (all in the thousands of dollars) who have all said that any quality company would have noticed the difference and at least spoken to the customer, much less order anything based on a notepad”

“Google+ photoshare for full story Horrible experience!!!! Awful service, poor quality work! Feel free to contact me for more information. Response from Allied is correct. These photos ARE in the middle of the project BEFORE they covered the horrible workmanship with chalk!!!! This is a siding company nad the siding WAS FINISHED, all that was left was the painting. Anyone can see the poor work. If you think poor cuts and misaligned trim is acceptable hire Allied. The painter used tube after tube of chalk to cover the gaps!!!!! 2 days after they finished the job my entire electric service fell off the house. I was lucky there wasn't a fire. I was on the roof to clean gutters and found large sections unpainted!! It clearly states in warranty that Hardy MUST be painted after installation. The crew came back after I complained about large gaps still noticeable and smeared more chalk everywhere and never came back to paint over.”

“We had a great experience with Allied Siding, William Oliver and his crew. They did an excellent job replacing the siding and shutters. We also had new gutters installed. The pricing was reasonable and allowed us to also replace the siding on our shed. I am so happy with the job they did; my house looks beautiful.”

“Allied did a fantastic job on our siding. Tim Nash did a great job explaining what w as going to happen when the crew showed up to work. Diago and his crew were courteous and friendly. This crew worked all day till dark! They were also very approachable. My wife had no problems talking to them. Our house looks awesome! I wish we would have done this sooner.”

“We had an excellent experience with Allied Siding and Windows. Tim was our salesman and Diego ran the construction crew. Both men as well as the crew were very polite, professional and did a wonderful job with our project. We had windows, sliding glass door and siding replaced. They also replaced the skirting. It looks beautiful! We expected them to be here for 5 days and the job was complete in 4.”

“Allied Siding and Windows did an awesome job on our house. It looks brand new. The construction team was outstanding and were very detailed. I highly recommend this company. Thanks to Tim and William and his crew!”

“Allied Siding and Windows did an outstanding job on our house. The price was fair and the construction crew were phenomenal. Tim, William and his crew were fantastic. Our house looks like new.”

“We selected Allied for a full window replacement and all new siding due to their other positive reviews, good experience working with sales team and price. This was a big and invasive job with people in and out the house for a week and a half. The PM Diego and his crew were awesome! Diego is super polite and communicative, and the entire crew was respectful. It felt like a super skilled team, and we love the outcome!!”

“Allied did an amazing job with the siding and painting. They were punctual and the team completed the job within the time specified. I would definitely recommend them.”

“Allied installed new windows, siding, and a door and I couldn’t be happier with their work. The team was professional and skilled and I appreciate the amount of effort Diego & his team made to make sure I was 100% satisfied. My house looks brand new and I couldn’t be more impressed.”
