My parents had work done by ABC Dry Foam and I must say they provide exceptional service overall. Any questions we had, they were always answered promptly, very attentive and walked us through each step of the way during this process. The house looks even better than before, and we are all very pleased. Anthony and Joey were friendly and always on top of things. We highly recommend this company for any of your restoration needs.
Anthony and his team were a great help with my home's fire restoration. They were professional, responsive, and efficient when I needed them most. Definitely recommend them any of your restoration or insulation needs!
My basement flooded and Anthony and his team came out in 30 minutes. This was after I called 2 other companies, they couldn't get out to my house for at least 24 hours. Once they got here they walked me through what needed to be done and got started. Great service!!!!

Koala worked me into their schedule at short notice. Their work was professional with great follow up. Everything was left neat and tidy in my attic and crawlspace. I noticed an immediate improvement in the comfort of my house. They also handled all the Energize Delaware rebate paperwork.
Koala Insulation of Newark DE are true professionals. Their experience with insulating an older home is second to none. We had them extract all of the old insulation & installed new throughout the attic space in our daughters home. Owner / operator that has a passion for his business explained what was needed. His Koala insulation team was on time, professional, and experienced with residential air sealing & insulation. 100% will use Koala with future homes
Matt and his team were wonderful to work with. I got insulation for my attic and in the knee walls in my Cape Cod style home. They kept me well informed through the whole job, we’re very professional, and worked with me in my schedule. Highly recommend!

I was rebuilding a concrete plant and building from the late 1940's. I had a block building that went through multiple reconfiguration over the years. The old fiberglass insulation rotted the plywood supporting the shingle roof. I had a new steel roof installed and consulted Kurt for an insulation solution. Kurt came up the next day and followed up with a quote too. He told me he was a few weeks out on another job but was certain he could knock this project out for me. Kurt and his guys came a week earlier than original start date and spray foamed and put a fire retardant paint over the foam in 2 days. I am completely satisfied with his work and the guys even cleaned up the job better than when they arrived. Seal-Right Injection Foam helped keep our costs down and maintain a tight project schedule. I will certainly call Kurt on the next project!
Kurt and his employees at Seal Right did an amazing job insulating my home. I applied to the Energize Delaware energy audit program and was recommended to have Seal Right do the work. I was amazed by their quality and professionalism. Even when the inevitable job site problems came up Kurt and his team redoubled their efforts and got the job done right! Seal Right was recommended to me and I will recommend them to anyone. A+ work Update: With the intense heat we've had this summer my house has stayed very cool. My unit does not run more often than usual and the temperature in my house has stayed perfectly comfortable. I am even more impressed with the quality of work done. The insulation from Sealright is going to make these increasingly hot and humid summer months more manageable and enjoyable.
Very impressed with Kurt, Shaun, & Shane (of Seal Right)’s professionalism, good communication, and reasonable pricing for insulation. They were also able to accommodate our busy schedule. The impact of good insulation (a warmer house on a cold winter night) was immediately apparent. We are very satisfied customers.
