"After talking with several attic clean out and insulation, wall insulation companies, I decided to go with Marathon Insulation. Johnathan was very helpful and professional, gave the best choices for my issues, without trying to upsell like some of the others. After getting the attic and walls insulated (with attic clean out) I can already feel the heat stay in the rooms much longer and the walls much less cold to the touch before. I highly recommend Marathon Insulation! They were always on time, delivered as promised, and cleaned up after."

"The professionalism and quality that the Insulation Labs team demonstrated from beginning to end should serve as a Master Class for any other service oriented company. Scheduling the estimate was effortless with clear, helpful and efficient communication from Diana, their first line of contact. Abraham arrived to do the estimate visit with kind patience and knowledge. He took the time to help us figure out how best to approach the insulation and was more than willing to answer all of our many questions. When we received the estimate we were appreciative of how easy it was to read and understand what the plan was. We knew exactly what to expect and how much it would cost. Today was the day of the insulation. Chris, Tzoc, and Moises spent a long full day doing the entire job. Throughout they were kind, professional, and did an outstanding, neat job. At all times, they cared for our space as if it were their's. We are so glad we chose Insulation Lab. There is no question we would recommend them to anybody."

"I’m extremely satisfied with their service! We hired them to do the clearing and installing for the new insulation in my attic a few months ago. It was very easy to set up an appointment over the phone. Adam, the owner, was very helpful every step of the way. They worked super fast to help install the insulation and disposed of the previous one. Great job and thank you guys!"

"We had no problem or issue with this company. They came and did exactly what they said and promised. The service was fast too. We were able to schedule them for the same week and the work was completed after 2 days of work. According to the technician that worked at our house, it was better to use the opportunity when the attic empty from the old insulation and to replace the ducts as well. For the price that we were able to got, we decided to do that too.
so overall, we are in the stage that we will use this company in the future and we will refer them to people that we know and might need the same kind of work to be done.

"Due to a water leak, we had fairly extensive damage in an area of our Master Bath wall. The job was difficult due to the area itself which was irregular in shape and in contact with the tub (caulking and paint damage), cabinet edge, window shelf, supporting woodwork and casement, and the tile backsplash along the adjacent countertop. Ciro examined the wall during our initial discussion and provided a formal estimate by email within two days. Upon approval, we scheduled a time for the work to be done and it was completed that morning. The texturing perfectly matches the surrounding area and it is extremely difficult to see where any repair has been made. We painted the repaired area, and couldn't be happier with the result."

"I am very satisfied with Best builders group. My main contact person was Zohar Regev who was very skilled and with great communication skills from the start of the work. Zohar originally set me up with his architect that worked with me to plan the room addition. The addition was an extra room and extended the back of the house. The architect took care of basically everything from start to end. The total price for the work was a bit higher than my budget but it was absolutely worth it. All the materials and final products for the work were high grade and the workmanship too. Zohar and his working crews worked each day including some weekends in order to get stay behind schedule. In the communication aspect of it, Zohar always kept me informed of the progress and what should I expect the following days/week. All my family and neighbors that visited my house, keep complement me about this work. Thank you Best builders group."
