"Javier who owns Dixie Insulation was very professional, and went out of his way to make me happy. I must admit, I'm very picky, but Javier's crue were punctual, and did a first class job. I had my old insulation taken away, and I went with the hard foam. There was hardly any smell, which I read, was because, it was properly mixed. I had one, or two small issues, in which Javier took care of them immediately. I highly recommend Dixie Insulation!"

"These guys took time from their busy schedule came to my residence on Easter Sunday to give me a price on repairing insulation mess left by previous contractor. They arrived next day and completed the insulation work and did an excellent job at an excellent price. My thanks to Sagittarius air seal thanks again, Michael Duffy."

"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"They are a very professional organization. Their workmen do a very good job and an excellent job of cleaning the area before they departed the job site. I can tell immediately that the extra insulation they placed in the attic is doing its job by reducing our utility bills."

"I got 3 estimates and this company was the best price. From the free estimate to completion of work, everything was so professional. They showed up on time with a 7-man crew, so the job was completed in one day. Six years after the job was done, my basement is still bone dry - so dry it actually gets dusty! My crawlspace is so low a person can only crawl around, but they did a great job there, as well, installing a thick white vapor barrier."

"When Mike did the free estimate, he told me it wasn't the walls where we were losing heat. It was my crawl space. Also, totally above the work of insulating the space, he noticed an air duct was disconnected. He got the straps needed to fix the vent and didn't charge me. Excellent customer service. He was neat, on time, and quick with the insulation."

Insulation questions, answered by experts

Through R-value assessments based on climate and existing insulation.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.
