RetroFoam of Houston

RetroFoam of Houston handles insulation work from Tomball. They focus on foam injection into exterior walls and perimeter walls of older homes that never had it installed. The owner stays hands on from the first estimate through the install day. Office staff handle scheduling and keep customers updated while crews handle the drilling and filling.

Homeowners bring them in for houses built in the 1920s through the 1970s that rely on whole house fans or have no wall insulation at all. Problems include high electric bills and rooms that stay too hot or too cold. Bobby and his crew plus Frankie handle most of the installs, drilling through brick or siding and filling the cavities. Results show up fast with lower power use, steadier indoor temperatures, and less outside noise. One job even covered a garage addition that had been poorly insulated before.

Estimates come out prompt and without pressure, often matching what other companies quote. Jobs finish in one or two days with full cleanup so nothing looks disturbed afterward. Crews stay in touch during the work and return if small fixes are needed. They drive from Tomball out to places like Galveston for estimates and installs. New owners have stepped in and handled warranty claims without any runaround.

“When doing some renovations last year I discovered my house was built with no insulation in the exterior walls. It was built in 1959 with a whole house fan instead of AC so the insulation was not needed. Fortunately I need to do some repainting anyway so they did the work from inside. I'm looking forward to lower electric bills this summer.”

“Don’t trust this company inside your home. I had an incident with them on July 11. One of their employees stole my gold chain 245 grams. I pointed who it was since he was the only one who went in that restroom. Chain Worth over 10k. I reported the incident with them the next day early in the morning July 12 and never got a call back from manager. I waited Friday and Monday all day and no help at all. Till I called on Tuesday and all they told me they were going to investigate. Yes I did a police report. all I wanted was my chain back since it hold something special. Just pointing out this for yall to be careful who you trust inside your home. *To the response* And no there was no other contractors on site. Don’t try to wash it off. What’s the investigation yall doing??”

“RetroFoam of Houston was an outstanding experience. The no pressure estimate given by Jon Tyrrell and his partner was prompt, thorough, and reasonable. Misty from the office was very pleasant, helpful and efficient with scheduling and communication. The installation team of Bobby and his coworker was performed with extreme care. These 2 guys worked non-stop for a day and a half on my 1 story brick home built in the late seventies when apparently exterior wall insulation was not much of a requirement. I have quite a bit of experience in home building, and the installation team were the best and hardest workers I've seen. They had to use much more product than they anticipated to fill exterior wall cavities. They were awesome with communication and punctuality. Experience couldn't have been better. Anxious to see how performance affects my utility bill.”

“We used GHRetrofoam to insulate the perimeter walls on our 1940’s home. Very professional, helpful, and great people to work with. Frankie took his time to explain everything on the first visit, the office staff was very accommodating as we had to reschedule multiple times, and Bobby (and the crew) were great on-site the day of install. Everyone was nice, communication was great, and looking forward to seeing the results in the coming months. Thank you for such a great experience!”

“I was looking to get foam injection insulation from a national competitor, but found the manager to be extremely rude there, so I came across Retrofoam and they did it for the same price quoted from the national chain. They came in and did it in one day and they even came back and fixed a couple of issues that were difficult to deal with. I am very happy with the service. Update New owners honored the warranty with no problems. a+”

“My home was built in 1928. Because of this, it had little to no insulation (only the more recent add-ons had it). With my high energy bills I looked into a few different options and settled on Retrofoam. There's plenty of info on their site's FAQ page, so I won't go into all of those details here in this review. Frankie and Bobby drove all the way down to Galveston from Tomball to do the estimate and the answer all of my questions. I scheduled the installation a few months later. It took two full days to complete the job. Bobby and his crew were very respectful of my property, friendly and knowledgeable about the product itself as well as the installation process. I had plenty of questions on how things were done and everything was explained to me in detail. Once they were finished, it looked like they were never there, which I also really liked about the experience. The jury is still out as to how much benefit I will see in the form of actual dollars saved, but I'm optimistic that it will be noticeable.”

“Great experience with Houston Retrofoam. The owner is very involved from sales to install. They took care with the job and did clean up afterward. It's been a few weeks and I can already tell the difference in how the house holds heat and cool Temps. The best part is that unlike the other company in Houston, the quotes are no BS and no pressure.”

“Bobby Castillo and his partner did my project which consisted of all my exterior walls and let me tell ya, they did an outstanding job. kept me in the loop through all steps of the job from estimate to completion. Even the ladies that do the "real work" in the office, my wife and I talked to were top notch. I will be referring my neighbors and friend to have this done. We can't wait the reap the benefits. Thanks to all!!”

“Just got this recently done. Very impressed with the standard of work. Bobby & his crew were professional, clean and prompt. Crew arrived on time and cleaned up afterwards. Felt results the day of installation. Will highly recommend them to family & friends.”

“Retrofoam of Houston came out today and insulated my garage walls. When completed you couldn’t even tell they had been here. They done a fantastic job. Bobby and Rabulaio were super great and very professional. I recommend them highly.”

“I can't say enough about the owner and his entire crew of guys. Being in the service industry myself these guys went above and beyond to make sure everything was done correctly and to my liking. Extremely responsive, above friendly crew and owner, along with efficient. Couldn't have asked for a better service experience. Im still adjusting to the new insulation as we have had it for a couple weeks I monitor my ac through my app and my fans of course do not run near as long as they used to the humidity level in my home is a lot better. As well as my neighbors barking dogs are no longer any issue lol. I would recommend these guys any day.”

“They did an excellent job retro fitting my house with exterior insulation! Very responsive, timely, and professional. Much more affordable than any alternatives and no gimmicks in sales. Highly recommend!”

“I recently used these guys to insert foam through our brick home. I will say that my wife and I were very pleased with the professionalism and knowledge of them. They were upfront and honest about the process from beginning to end. I find it extremely hard to locate any of the holes in the morter after the process was completed. We are looking forward to test the results as weather get warmer..So far it seems to hold the temp very well and cooler. I currently have my A/C set to 80 degrees and it feels like 78 and crisp. If I had another house I would recommend Houston Retro fit in a heartbeat. Thank You”

“These guys are great to work with. Came exactly when they said they would. I was worried about my Hardi-Plank siding, it’s very fragile, but the guys didn’t break a piece. We had a small addition to our home that was poorly insulated, this is what we had done. I tested with a temperature gun, and you can see the difference. Looking forward to a warmer day to see how it does then. Highly recommended.”

“I would give 10 stars, 100 stars if I could. Frankie and his team got in and out, did EXACTLY what they said they were going to do, and my home thanks them for it. My light bills were about to extend my retirement age until Frankie put an end to that. My AC isn't working as hard, my house stays cool, and the entire process was painless. This truly is an investment in your home and I highly recommend!”

“Highly professional and excellent pricing. The RetroFoam Insulation work they performed had a significant impact on the temperature of my garage, and this also cooled down the rooms above the garage. This worked saved me from having to remove my existing drywall and the work involved in installing insulation the traditional way. I highly recommend this business.”

“Thank you Greater Houston Retrofoam for saving me money on my monthly electric bill! Thank you to the team of professionals that came out and installed the retrofoam on my over 30 year old home to make my home more energy efficient. Great price, great service, great savings!”

“We experienced the hotest summer in Houston I can remember this year but luckily i haf the insullation work performed in May. My electricity usuage over summer was significantly lower compared to previous years, on avergage more than a 1/3 lower. And this was for a 12 yr old home too. Yall, I highly recommend injection foam !!!!”

“They installed foam inside exterior walls . I was impressed with the noise reduction from the outside but also a bonus with keeping the cold or heat from coming inside our house .So we didn't have insulation in those exterior walls.”

“The crew did great work and were fun to be around most of the day. Bobby and his crew were very professional. They even cleaned up the house more so than the way they found it.”
