"I communicated with Ron directly and he was determined to solve our insulation problems. He had to remove drywall in our entranceway and add in insulation where there were large gaps and air was getting in. He had a worker drywall and patch up the wall. The drywall worker did an amazing job! 
Ron also fixed an ongoing issue we had in our garage ceiling that was causing our living room floor to be cold and drafty. He worked around our schedule and made multiple visits to our home to fix the issue. We are happy customers and happy to say that the problem is fixed. We were very pleased with Ron and his company and do recommend him highly.

"Had concrete sidewalk slabs leveled, was out of level about 3" to each other and twisted one sided, fantastic job was done, results better then expected. I would highly recommend this company for leveling jobs. I rated customer service lower because pre hire communication was lacking at times"

"I cannot recommend barrier spray foam enough. We had been looking for a company that I felt comfortable doing our spray foam insulation in the completely un-insulated attic space for a few weeks before I found Robert Keeney from barrier spray foam and I am extremely glad that I was able to find them because I could not be more pleased with the service and the quality of the work that they produced. Robert was incredibly efficient, showed up exactly when he said he would to do a free estimate, he was very good at explaining the R values and the percentage that they would actually insulate the space and what his recommendations are and for that I am extremely grateful. The other companies that we had to quote did not go into this level of detail! Barrier spray foam helped me to feel very comfortable that they were doing everything they could to make sure that the work that was done was what the space needed, and the quality was top notch. We received their very reasonable quote exactly when he told me I would, and not once did I feel that communication was lacking. We were scheduled quickly and on the morning of the assigned day Robert and his crew showed up promptly, they had everything they needed to start work very quickly, they all wore masks and were very respectful of our space and putting down tarps to cover everywhere that they walked. They started promptly, explained what they were doing, explained where they were throughout the process and let us know when they were ready to leave. They were in around 8:00 AM and left around 2:00 PM, their work is incredibly neat and we can't find a single fault with it! Thank you so much Robert and team from Barrier spray foam!"

Insulation FAQs, answered by experts

The primary purpose of insulation is to maintain comfortable temperatures in a home, whether that’s cool air when it’s hot out, or warm air in winter, but that’s not all it can do. All options will also minimize heating and cooling needs, lowering both your carbon footprint and energy bills in turn. And some options, like rigid foam boards, even offer soundproofing benefits, too.

Yes, cold walls are a common indicator of poor or inadequate insulation, especially if the walls feel significantly colder than the air in the room. This suggests that heat from your furnace is escaping rather than being retained. The issue could be that the walls have no insulation, or that the existing insulation is old or has been damaged by water, moisture, or pests. Your best course of action is to hire a professional to investigate. An insulation contractor can determine if you need to add or replace insulation and can often perform the work without creating large holes in your drywall. If you suspect the problem might also be related to your heating system's performance, an HVAC technician can take a closer look.

Don’t install insulation near water heaters, oil burners, or any other object that gets hot. Many insulation materials are fire-resistant, but not entirely fire-proof, so you should take precautions to keep hot things away from fiberglass. This is also why it is imperative to box off lighting fixtures and breaker boxes.

Open-cell foam insulation has a life span ranging between 15 to 25 years when well cared for. However, the material may degrade sooner in areas with high humidity or after prolonged water exposure. Proper installation and maintenance can maximize its longevity but requires close monitoring. Closed-cell foam insulation has a longer life span of 30 to 50 years.

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.
