"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."

"We have worked with many different contractors over the years and have been turned off of construction in general. None of our previous projects have ever gone smooth. The opposite can be said about home genius Exteriors! Joe was in communication with us throughout the project and made sure any issues and concerns we had were addressed immediately. This has been a really good experience and I highly recommend home genius Exteriors."

"Rightway Waterproofing is the company you want to come and waterproof your basement. I had initially set up a job looking for pros through Angie's List. I was contacted by Rightway Waterproofing via phone and email but did not respond as life happens. Well it rained really heavy again in August and I had more water in the basement. I reached out to them on a Friday and Albert contacted me immediately. They were able to come out on Monday to look at my property. Jake was thorough and friendly. He let me know what he thought we needed, explained everything thoroughly and gave us a quote which was completely reasonable. We accepted the bid and work was to commence on Thurs as they had an opening. Work was completed in one day. The area was kept pristine and they did an amazing job. The crew was courteous to my family. I could not recommend them more. I hope to have them out again at some point to finish my basement area as well. Try to keep in mind that during the season of covid many families are looking for ways to make more space in their homes or to have to home projects done. If you are waiting for work to be done just know that it is worth it! Thanks Rightway!!!"

Insulation questions, answered by experts

Routine maintenance for insulation service involves conducting comprehensive visual inspections twice a year. Check your attic for moisture damage in the spring after the Dover freeze-thaw cycle, and inspect again in November following hurricane season. Examine crawl space vapor barriers for tears or pooling water. Always clear bird and wasp nests from your soffit vents to maintain proper airflow throughout your home.

Helpful?

Address immediate needs like moisture, mold, or winter pipe freeze risks right away to protect your home. Dover experiences high humidity, so compromised materials become a rapid mold hazard. If your current setup is functional but simply falls below modern DE energy codes, wait to schedule insulation service for the fall. September and October offer the best conditions before the heating season begins.

Helpful?

After completing insulation service, always schedule a final municipal building inspection to close out your permit. Next, hire a local HVAC professional to recalculate your home's heating and cooling load. Your equipment requirements change after major energy upgrades. Finally, verify that all soffit and ridge vents remain completely unobstructed, and monitor your indoor humidity to ensure it stays balanced for the DE climate.

Helpful?

Visible mold, musty odors, or moisture stains indicate an urgent need to redo your insulation service. In the humid DE climate, saturated materials lose their effectiveness and require complete replacement. Look for signs of pest tunneling or compression from rodents. Persistent drafts, winter ice damming at the eaves, or unexplainable spikes in your monthly utility bills also signal failing thermal barriers in your Dover home.

Helpful?

Completing insulation service drastically improves indoor humidity control during hot, sticky Dover summers. Upgraded materials block moisture vapor and buffer the rapid temperature swings common during the spring and fall. Proper coverage also reduces infiltration from outdoor allergens and dust mites. Additionally, adding acoustic barriers to your walls and attic significantly dampens overhead noise from aircraft flying out of the local air force base.
