"From initial contact with their sales department we've had a great experience, Corey did an excellent job of taking pictures and showing the problems in our attic. Their level of communication from emails to phone calls was precisely correct by contacting me when needed and not too much with pictures detailing each solution and its associated cost. On the first work day their crew called ahead of time, arrived promptly and came prepared with masks, plastic sheeting, full body outfits and cloth covering for the stairs. In just over 6 hours they had cleaned up the entire attic removing bad sub-floor and other insulation, laid out the foundation for building a large deck space and placed part of the first layer of materials down. They also sealed the attic door along with some of the air vents and ceiling fans. They completed insulating my front porch overhang and cleaned up all of their mess very well. Painters tape was used on corners where they we’re most likely to bump into it for protection and plastic sheeting was setup precisely where needed to keep dust off of our hallway things next to the attic entrance. Overall it was a great first day and they even spotted an issue from a previous vendor who failed to properly connect some of their duct work together (which was the original cause of my daughter’s room temperature being so hard to control the temperature and not easy to spot). The only complaint I have is that while I fully expected the need to finish our attic sub-floor, remaining layers of TruSoftTM Cellulose on the main floor and encapsulate the duct lines with Polyurethane Spray Foam all before finishing with blown-in insulation, they left a key piece incomplete. When leaving they left the duct work leading from our main trunk line to my daughter’s room off. This left a hole in the main trunk line reducing heat in all upstairs rooms but most important is that nothing was connected to my daughter’s room. So around 6:00am she woke up coughing as we noticed the upstairs was around 56 degrees. Overall a simple heads up would have solved everything as we have space heaters, however I did not look into the attic when they left so that’s my fault for not knowing a key piece of the duct line was missing. Based on the overall work complete I would still very much recommend them as Robert (onsite team lead) was very good at communicating and the crew we’re all quite friendly. Their work will last for the lifetime of my house and has already added value to the sale price. In the end they made a really nice attic deck leaving me with plenty of useable storage space. While this is not the cheapest company, the quality and knowledge that I never need to worry about my attic again is certainly worth it."

"We had a great experience with Discount Energy Services. They insulated our entire attic and crawl space, and from start to finish they were professional, responsive, and easy to work with. The turnaround time was impressively quick, the quality of the work was excellent, and we felt the value was very good for the scope of the project. The team was efficient, knowledgeable, and clearly took pride in doing the job well. We really appreciated how smoothly the whole process went and would gladly recommend Discount Energy Services to anyone looking for high-quality insulation work."

"These guys were great. Allen met me at the door with a firm handshake told me what they were about to do and if I had any questions just ask. Leo was just as professional during insulation and got the job done in 3 hours. Dylan kept me up to speed during both projects and was very helpful. Easy reccomendation."

"Bill knows what he is doing and holds himself to high standards. We wanted to upgrade the attic, and when he left, we have insulation carefully and well placed and blanket over the access. I'm very satisfied. This attic is now really well insulated, he did a little caulking around the access stairs, came on time, got done a little more quickly than he had estimated, and everything nice and clean."

"Kelvin, the owner of the business, did a fantastic job with my project. He answered my call, was able to come by to look at the project promptly, knew exactly what I needed done, and made this process very easy with a reasonable quote as well. I had plywood flooring down and he and his guys unscrewed it, moved my attic items around to get full access in stages and sucked out all the old insulation, while covering my stairs and hallways with drop cloths. They were clean, respectful, efficient, showed me what was happening along the way, and did a stellar job. They added foam insulation and blown-in insulation, reinstalled my flooring and left the job in very good condition. I am very happy to recommend them!"

"I got 4 estimates to insulate my attic. Homeland's was the best. They came when they said they would and did a good job. I paid for R49 but they gave me R60 over much of the attic. And they cleaned up before they left. On top of that, the owner introduced me to a carpenter who helped me install a patio door (or rather I helped him install my door)."

Insulation questions, answered by experts

For your safety, you should always wear a mask when cutting batts of fiberglass insulation. We also recommend wearing eye protection, safety gloves, and long sleeves to protect your skin. Properly suiting up helps you avoid several fiberglass issues, such as cuts from the tiny shards of glass and inhaling small bits of fiberglass.

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.

If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses.
