"He asked that I call him in a month and give him an update on how my soundproofing plan was working. I've had my outside noise problem for a very long time, and after talking to Andrew, I now have a very good plan! It was a relief learning what things I could do to solve my noise problem. My highest compliments to Andrew Horvath for his patience and guidance. Thank you. Bruce Scarborough"

"Very pleased with the customer service and the quality of work done by AHC Spray Solutions. The owner, Clint, was on time for his initial appointment and was efficient in evaluating the job and providing an immediate estimate to complete the work. The workers showed up to do the job on time and did the prep and post-job cleanup very well. I am pleased with the work and recommend AHC Spray Solutions to anyone needing spray foam insulation work. If I need another spray foam insulation job, I will call AHC."

"I had Ben come back out again and he did our fireplace which now absolutely looks like new. We had asked our property manager when we were stationed away to ensure this and other tasks got done. The property manager apparently never did this task. Dave arrived on time and worked diligently - he also took the time to educate me on all the functions and how he cleans (the process, the materials, and the safety checks) - which made it a class + a cleaning. It was simply awesome. His efforts, timeliness and great prices are once again truly appreciated. During this visit he also streamlined my dryer vent to remove the multiple 90s and improve the airflow. Talent, great price, and hometown service - who could ask for more."

Insulation FAQs, answered by experts

While there are many different kinds of insulation, spray foam, blown-in, foam board, and batt and roll are the four types you’re most likely to see. That doesn’t mean they’re alike, though. Each one varies drastically in terms of cost, materials used, and how they’re installed—not to mention, how well they limit heat transfer.

Yes, PEX pipes should be insulated in certain situations. While insulation is not always necessary for pipes running through insulated interior or external walls, it is recommended for any pipes located in uninsulated rooms, unheated areas, or outside, especially in regions with cold winters. The primary reason is to prevent freezing. Although PEX is more resistant to cracking from freezing than other materials, repeated freezing and thawing can weaken the pipes over time, increasing the risk of a burst.

Whether plaster walls should be insulated depends on whether the walls are at particular risk of moisture problems. In many cases, you can insulate plaster walls, while in others, it's a poor decision because of the lack of a vapor barrier. Choose a reputable insulation contractor to help you decide if and how to proceed to increase your home's energy efficiency.

It’s best not to install a radiant barrier directly under insulation because it requires an air gap on at least one side to work properly. Instead, you should install the radiant barrier over your existing insulation to create an air space to reflect the radiant heat.

Reduces energy costs, improves comfort, and prevents ice dams in winter.
