If you have a custom stucco home I would avoid this company. I was excited to get a quote from this company. When they came out, they suggested they would need to put trim around my doors where currently I have no trim. My stucco wraps around door frame for a polished look. This is the front of the home. Window Source of Houston will not do that kind of work. They want to trim it which would degrade the look of a custom home. For the back of the home where I have two 120”x96” needing replacement, the gentleman initially said the stucco would not be a problem, that they remove the doors from the inside. Two days later I received a call they will pass on the job for reasons mentioned above. They do not have a stucco guy on staff and hence will not cut stucco back to do the install correctly. The owner did call and explain the reasons, however it’s frustrating how they advertise: “Our replacement doors are custom-built ensuring a perfect fit and seamless integration with your home. With skilled craftsmanship and advanced technology, custom built solutions offers a perfect blend of aesthetics and durability.” So I guess perfect blend of aesthetics is in the eye of the company and not the home owner. And even with skilled craftsmanship and advanced technology, they still can’t install a door because of stucco restraints unless you’re willing to go trim. Update: Within a hour of sending this review, the owner text me threatening legal action which makes me question if all the 5.0 reviews are legit or whether many people have taken down their reviews. From the owner: “I will be filing with my attorney a defamation suit and will be sending a formal cease and desist letter”.

We understand your frustration and appreciate the opportunity to clarify our decision.

First, we would like to clarify that we work on stucco homes throughout the Houston area on a regular basis. The concern was not that your home has stucco, but rather the specific custom stucco application surrounding your door openings and the level of stucco modification and restoration required to achieve the exact appearance you wanted.

During our evaluation, we determined that replacing the doors while preserving that exact stucco finish would require specialized stucco removal and restoration work that falls outside our scope of expertise. Rather than risk compromising the appearance of your home or delivering a result that did not meet your expectations, we made the difficult decision to decline the project.

At Window Source of Houston, we believe it's better to be transparent about our limitations than to proceed with a project where we cannot confidently deliver the quality and finish our customers deserve. While our replacement doors are custom-built for each home, certain highly customized stucco applications require specialized exterior restoration work that we do not perform in-house.

We appreciate your feedback regarding the communication during the quoting process. While our initial assessment suggested a possible installation path, a more detailed review led us to conclude that we were not the best fit for your specific project. We understand this was disappointing.

That said, we are disappointed by the 1-star rating. We responded to your inquiry, visited the property, carefully evaluated the project, and me the owner personally called to explain our decision. We chose not to move forward specifically because we did not feel we could deliver the finished result you were seeking. While we respect your opinion, we do not believe a 1-star review accurately reflects the level of professionalism, honesty, and transparency demonstrated throughout the process.

We sincerely appreciate the opportunity to quote your project and wish you success in finding a contractor who specializes in the type of custom stucco restoration your home requires.

****Update****
We also want to clarify that no legal threats were made. Our communication was a formal response addressing statements we believed to be inaccurate. Under Texas defamation laws, businesses have the right to address potentially misleading public statements, and our message was limited to that purpose only. It is also not typical for a company to face this level of dispute after declining a project, as we ultimately chose not to proceed with the work and therefore did not enter into a customer relationship.

Window Source installed windows for me. They were so professional and fast with the installation. Lewis Roldan was excellent in explaining how to work and clean my windows. He made sure everything was spotless when they left. Thank you Lewis.

⭐⭐⭐⭐⭐ I recently had six windows replaced by The Window Source, and the entire experience was excellent from start to finish. The sales representative was knowledgeable, professional, and easy to work with. Communication throughout the process was clear and consistent, which made everything go smoothly. The installation crew was outstanding. They arrived on time, worked efficiently, and completed the entire job in about half a day. They treated my home with respect, cleaned up thoroughly when they were finished, and left everything looking great. The new windows have made a noticeable difference. My house is cooler, the windows look amazing, and I'm already seeing the benefits of improved energy efficiency. Best of all, I no longer have to deal with the issues I was having with my old windows. I intentionally waited until after a heavy rain before writing this review because I wanted to make sure the leaks I had experienced were truly resolved. I'm happy to report that after the rain, there were no leaks at all. The windows performed exactly as I hoped they would. One thing homeowners should keep in mind is that The Window Source specializes in window replacement. If you have wall damage from previous leaks, you may need a separate contractor to repair that damage. In my case, they replaced the windows professionally and worked around the affected area as expected. The pricing was very competitive, and the value for the money was exceptional. Between the professionalism, quality workmanship, great communication, energy savings, and leak-free performance, this was an easy 5-star experience. I would definitely hire The Window Source again and highly recommend them to anyone considering new windows for their home.

It's been about 6 weeks now and they're not what I expected. I had solar screens and now I have 1/2 regular screens. You can view right in and that's definitely not what I wanted. But you live and learn. 🤔
Reply from Window Source of Houston 2026.06.01
Thank you for sharing your feedback. We're sorry to hear that your new windows have not met your expectations regarding privacy. We understand how important it is for homeowners to feel comfortable with both the appearance and functionality of their windows.

The screens included with replacement windows are standard insect screens, which are designed primarily for ventilation and protection from bugs. Solar screens, which provide additional privacy are a separate product and are not typically included unless specifically selected as part of the project. It was never mentioned that you were expecting the same privacy from the new windows. We appoligize this was an expectation.

We would welcome the opportunity to discuss options that may help achieve the level of privacy you were accustomed to with your previous solar screens. Please feel free to contact our office so we can review your concerns and explore possible solutions. We appreciate your business and the opportunity to serve you.

My salesman Steve was great he went through everything with me and we agreed upon what I needed. Pricing is amazing compared to other companies that I had come to my home. My windows and doors will be installed late May early June and I am so excited to be able to get them replaced.

Initial contact after inquiry gave me Renewal by Anderson vibes with the sales pitch by text . Immediate turn off as I loath Renewal by Anderson approach. I decided to make an appointment anyway due to the company being veteran owned and claim to have competitive pricing. They sent a younger salesman out. He was well-versed very thorough brought a sample of the Window took his time explaining everything answered questions and the pricing was very good. I had a quote from a local person already so it was kind of in the ballpark of that but this is by a more professional company and I felt like they would do a better job and I had a better Warranty and felt better using Window Source . I went ahead and put 50% deposit down and decided to order that day. They were here cause they gave me a an incentive to purchase today if I wanted and we were ready to do it and I’m glad I did . The crew they sent out did a fantastic job. They came out around eight or 9 o’clock and finished around three and I had nine windows replaced . They did a fantastic job, very thorough. They covered all the furniture put pads down on the floor wherever they walked. It is a dusty operation when you’re cutting into the window frames cause these windows are deeper than what I had. They flashed everything, caulked and cleaned up throughly . I highly recommend their company for the quality you get and the service. Great communication from start to finish. can’t say enough nice things.

This company is amazing from start to finish!!! Every single person that you are in contact with is beyond excellent!! They stay in constant communication throughout the entire process and answer any questions you may have! I didn’t think it could get any better but then I met Luis and his crew the day of the install. He exceeded all of my expectations. They were kind, respectful, hardworking men who did a superb job with my windows!!! Last but certainly not least, the star of the show, my windows!! They are spectacular ! Beautiful in every way. The window source has delivered on every single promise!! I can say that I already had to raise my air up a bit because they are doing their job. I can’t wait for summer and to have a lower electric bill! This was the best decision we could have ever made !

Window Source of Houston is amazing! Veteran owned. Show up on time, each tech had their own specialty and all three of them were in sync doing the best work. Cared on 9 windows with drop sheet from ceiling to floor. Not much dust, reinspected each window on walk thru. Started 8:30am- all done by 4pm. Respectful, reliable, honest, and company donates a percentage to veterans. They came, measured, sent quote and NEVER was pushy. Other companies wheeling dealing, pushy, promises, talk badly about competitors. Window Source was spot on trustworthy.

We had 11 windows installed. Luis Roland and his team (Abel and Marco) did a wonderful job. They were very neat, courteous and went out of their way to provide the best customer service. Luis re-installed our vertical blinds and cellular shades. The new windows are beautiful. 5/4/26 Today we had 6 more windows replaced. Luis and his team did an excellent job. They again were courteous, neat and respectful. The windows are beautiful. The arched windows fit perfectly.

Great experience! After much uncertainty, I finally decided to get the windows on my house replaced. The entire process, from meeting and getting an initial quote from Collin, to the ordering of materials, scheduling by Lindsey and installation of the windows by Edwin and crew, I can say this has been a great experience. All employees were very easy to work with and all did an outstanding and professional job. Very meticulous and neat work. Love the windows! Highly recommend!
