Testimonials
BEYOND EXPECTATIONS is all that I can say!
Positive: Professionalism, Punctuality, Quality, Responsiveness, Value
I selected Mark and his team upon seeing his work on our neighbors' house and hearing how great he is to work with. This was even after I interviewed a competing company that I was sure I was going to commission. Mark and his team put in our windows, the Hardie plank siding, and paint. His workers are the most professional and patient in the business. On more than one occasion I changed our initial plan. Neither Mark nor his team batted an eye. Lastly, Mark was on site daily to talk through the project's current status and ensure if I had any questions they were immediately answered.

I only wish I hadn’t put it off so long
Positive: Punctuality, Quality, Responsiveness, Value
This past week I finally had new windows installed. I knew it was past time. I had Mark with Alamo Exteriors Siding and Windows do the job. I had no idea what an incredible difference it would make. Mark was very easy to work with and professional as well as his installers. I had 26 windows replaced. I only wish I hadn’t put it off so long. Craig (Boerne)

I would not hesitate to use Alamo Exteriors
My house is 29 years old. It needed some attention. I was hesitant to hire someone because I wanted quality work performed. Fortunately, Mark was siding a neighborhood house. The neighbor's referral and quality work prompted a call to Alamo Exteriors. Alamo Exteriors installed new siding, windows and painted the house. Mark's team did a professional job bringing the house to better than new condition. Mark personally performed several jobs himself to ensure top-notch quality. He also spotted & implemented small ways to improve the weatherability of the house exterior.
I felt that my house was being treated like it was his own house. I'm thankful for all the work Alamo Exteriors performed. I would not hesitate to use Alamo Exteriors.

I would recommend Alamo Exteriors to family and friends without hesitation.
In fact, I already have. In September of 2015, I had all of the windows in my home replaced as well as the 30-year-old cedar siding. At the time, I was very pleased with the work crews and the quality of their work. I was especially pleased with Mark's attention to details and keeping me informed regarding the progress of the job. It has been almost 6 months since the job was done. I intentionally waited to write a review because I wanted to include any customer service issues after the job was completed. There were a few very minor things to be addressed and Mark was out here within a day to take care of them.
This was a huge job and I cannot praise all of the people associated with Alamo Exteriors enough. Everyone was hard working and considerate of my home and property. Everything was cleaned up when the job was finished. Mark kept telling me I would love my house when they were finished...He was right. It looks beautiful but more than that it will be maintenance free for as long as I am here. I have already noticed a savings in energy use and there are no more hot/cold spots in the house.

Mark and his team were great!
They worked around our schedules and the installs were done within a few hours. He is responsive and quickly responds to any questions or concerns via text or call. It was a great experience and our windows are exactly what we wanted! Alamo exteriors met our expectations and I would highly recommend them.

I highly recommend Alamo Exteriors!
We are very pleased for several reasons: with their (Mark)'s advise which windows (within our budget) we should install in our home, with how neatly the work crew performed their work, and last but not least, how the windows changed the appearance of our 30-year-old house!

This is the second home of ours that Mark Belto and his capable crew have installed Hardie Plank on and painted, In each case, we have had the same crew of professionals, and their work has been consistently outstanding. Mark supervises his crews work admirably and keeps you informed of progress. In both cases we have been thrilled with the end result and wouldn't hesitate to use Alamo Exteriors again. Thanks Mark!"
