"We badly needed insulation in our attic. We got three quotes. Weather Shield was not only the most reasonable, but the only company in which the owner both gave us the quote and installed the insulation with colleague. We could not have asked for more professionalism or better service. Would highly recommend Gus."

"Arc was great from the start. We were given a complimentary consultation by Steve Garrett, who gave us a detailed explanation on the issues we may have with our attic insulation and why our energy bills may be so high. We chose to have our attic insulated and our ducts sealed. Our ducts saw a 93.5% improvement, and we immediately noticed the difference in the temperature of our second floor. Even during this prolonged heat wave, we have been able to keep our temperatures much lower than before. The attic insulation has also decreased the temperatures of the upstairs. It has been a remarkable difference. We are fully expecting our house to be more comfortable in the winter as well. Steve is honest and reliable and we would not hesitate to recommend Arc to anyone who needs insulation and duct work."

"I am very happy with the work done by Green Attic Insulation. David and Charlie were very friendly, professional, responsive, and flexible in working with my changing needs. I originally was looking into insulation but then discovered there was mold in my attic. As the job grew, David, Charlie, and their team worked with me to address the additional parts of the job. I really appreciate their knowledge and the thorough job they did. They took many pictures of their progress and kept me informed each step of the way. Thank you very much!"

"We used Perma Seal for several big projects—waterproofing our basement and replacing our concrete back yard and sidewalks. We had drain tiles, sump pumps and a dehumidifier installed, along with extensive concrete work outside. We dealt with a variety of crews and found everyone to be very communicative, professional, and knowledgeable. They did great work and kept us informed at every step of the process. When we had a questions, they were very responsive. All in all, we'd recommend and use them again."

"It went fairly well. The man in charge of giving estimates gave me confidence. The man in charge of the work was a bit of a fast talker, however. I have waited over a year to finish this review b/c I wanted to wait until I got door into the porch from the house and for cold weather to see how well the insulation works. I do not have a heat vent on the porch. Was hoping the insulation along with a small electric heater would keep it warm. The contractor thought it would be okay without a heating vent. For most part it is, but with very cold weather, the porch gets pretty cold. I may have been hoping for more than was realistic and may eventually get a larger electric heater or get a vent from my furnace if I decide to use the room more regularly."

"Literally a truckload of dirt and old insulation was removed from a crawlspace under a town house. Openings in the foundation were sealed or covered, the floor was swept clean and the crawlspace walls sprayed with insulating foam. 2-day job in tough conditions and with limited city parking, professionally and efficiently executed, indeed resulting in a perfect crawlspace. Top marks. Thanks to Greg, Jim, and the crew.

"I had three different people groups in who came in and gave me an estimate and what might be needed and what they discovered is that for some reason when the house was built 16 years ago, they did not really do adequate insulation.  I did feel very comfortable with Precise & Snug.  They were good about being able to show me pictures.  They showed how it looks up on the attic.  When you are in the process, the told us that they can do this and that and it would cost so much and the final bill was $20,000.  I would not use their service in the future."

"

I have an apartment building in which the garden unit had previously suffered water leakage.  I had the outside sealed previously, but wanted to get the inside sealed while the apartment was empty.  Chuck came out and offered three different solutions all with various price points.  We agreed to sealing just the inside for now, and if there were future leaks, we would consider the alternate solutions proposed.  In all 6 cracks were discovered.  Chuck had the cracks sealed and each of the tie bars sealed. 

I will be using them again for my other apartment units.

Insulation questions, answered by experts

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.

While insulation is required for all exterior walls in a house, it is not typically required for interior walls. Local and state building codes mandate that new construction homes have adequate insulation in exterior walls and ceilings to suit the local climate.

However, there are several benefits to adding insulation to interior walls. It is excellent for sound-dampening between rooms and can help with temperature control by maintaining a regulated temperature in specific rooms and lowering heat transfer between adjacent areas. Insulating interior walls can also contribute to the overall energy efficiency of your home.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise. 

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.

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.
