"Dillon and his crew did an excellent job. They showed up on time and didn't take any breaks until the job was done. Our rooms upstairs are at least 10 degrees cooler because of them blowing in the insulation. I highly recommend them for any service they do, you will not find a better company to work with you, plus they got us a rebate with the power company so you can't beat that. Thanks so much"

"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."

"I like working with this company. Rob Blake, the owner, is very professional. I called him because a hot water heater problem had revealed that the foam from a 2011 job had not filled the cavity in the wall as thought during the 2011 job.  I did not know if this only applied to the water heater closet or to the entire cabin.
Rob's response to my call was "That's why you have a lifetime warranty!"  Wow.  Not used to that.  Rob came out the next day and crawled around under the cabin and poked wires into outlet cavities and showed me that the foam was only thin in the water heater closet, and given the construction of the closet, that made sense.  Rob wanted to schedule a return within a few days to fix the problem before the weather got cold.  I asked him to bid the top floor of my house to do at the same time.
The fix was free and the top floor of my house was 3200.  So altogether, I have spent $7100 with retrofoam, to insulate three houses; one about 750 square feet; one about 450 square feet and one about 4,000 square feet.  
As with the first job, the workers were polite, professional, hardworking and very thorough. They were very nice about things like taking down a bird feeder for me - not part of their job at all, and they were happy to help me with it.  They do have to come inside to listen for something when certain walls are being injected; they were always very polite, wiped their feet and so on.  They worked from 8 to 5 every day, and they did an excellent job of cleaning up after themselves.  The job was planned for two days but took three.  They were very inobtrusive with my renter whose water heater closet they redid.  In fact, they removed some fiberglass insulation near the water heater placed during the water heater repairs not only because it was ineffective but because the type that was there was a potential fire hazard (the paper side was near the water heater).  This is pretty typical of them; they have gone above and beyond on every job for me.  They really do work as if they were insulating their own homes.  Very nice.
The only almost-rough spot is that my cabin and my house had to be drilled right through the exterior siding, and after the holes were plugged, we needed to repaint the house.  The 750- square foot house needed to be painted anyway so I didn't mind, and I planned the big house job to coincide with a painting soon after because I remembered that from last time, and it also was due for a repainting.  Rob tells me that only five houses so far have had to be done this way; but I would ask him before the job if the house will need to be repainted as it would have been a pretty rude shock to not realize this ahead of time.  I understand that most jobs do not result in a repainting, this was about the type of siding we had on our houses.
In fact. Rob offered to supply the labor to restain the plugs to match the siding, but since we are repainting soon, we didn't see any need.
The insulation has been astonishingly effective.  Not only in retaining temperature, but also the houses are now so very quiet.  This has been an excellent investment in our house, and we are very happy with the outcome.  Also, this is a very professional, easy to deal with company.

"We had an issue where our subfloor was saturated with moisture and completely covered our crawlspace with mold. We thought we were going to have to rip out our kitchen and subfloor. Moisture Solutions responded quickly and offered short term and long term solutions to our situation. We didn't have to rip anything out, saving tons of money, and now our crawlspace looked better than the day we purchased our home."

Insulation questions, answered by experts

In Greenville, it’s time to schedule insulation service if you notice uneven room temperatures, rising energy bills, or persistent indoor humidity. Pay attention to hot spots in summer or chilly drafts in winter, as well as visible insulation damage or pest activity. If your home is over 15 years old or you’ve recently moved in, a professional evaluation can help identify areas for improvement in comfort and efficiency.

Helpful?

In Greenville, insulation service should be prioritized if you notice persistent drafts, unusually high utility bills, or rooms that feel damp or musty—especially during humid summers. If your attic or crawl space insulation appears compacted or discolored, it’s best to act quickly. Homes with consistent comfort, recent insulation upgrades, and no moisture issues may be able to wait, but regular inspections are still recommended.

Helpful?

New homeowners in Greenville should start with attic insulation to reduce heat gain and loss, then focus on air sealing to prevent humidity and drafts. Insulating exposed ductwork, especially in crawl spaces, is also important. For homes with unfinished basements or crawl spaces, adding insulation with a vapor barrier helps control moisture and improve home comfort, particularly during Greenville’s humid months.

Helpful?

Completing insulation service in Greenville can significantly enhance your home’s value and resale appeal. Buyers are drawn to homes with improved comfort, lower utility costs, and features that support energy efficiency. Upgraded insulation also helps manage indoor humidity and moisture, which is especially important in Greenville’s climate, making your property more attractive to those seeking modern, sustainable living solutions.

Helpful?

After insulation service in Greenville, inspect for proper air sealing around windows and doors, and verify that your attic and crawl spaces remain dry and well-ventilated. Monitor your home comfort levels and utility savings over the next few seasons. It’s also wise to check for any signs of pest activity or insulation settling and schedule periodic professional assessments to maintain peak energy efficiency.
