"This was an absolutely professional and expert job from start to finish. I needed insulation installed to replace the old insulation in my attic. The scheduling was easy, communication was flawless from start to finish, the job was done right and quickly, and my house was cleaned up at the end. Additionally they are insured and let you know that right off the bat. Absolutely recommend this company!"

"Perfect ! These guys are real pros. They have previous experience, and have gone out on their own to do it the right way. They are professional, knowledgeable, personable and they know what they are doing in both areas (critters and insulation). On time in zero degree weather. Cleanup was spotless. You would never know they were there. Would use them again in a heartbeat."

"I highly recommend Jason and Craig there at Mold Blasters. They did and absolute phenomenal job on reinforcing the wall in my crawl space that had begun to bow. They also encapsulated the crawl space which makes me feel so good and reassured that no mold will now form. I cannot say enough about this company. Jason is very honest and follows thru with what he says. You don't get that often these days. I would give more than 5 stars if I could. Good honest work. Thanks again Jason and Craigð  ¥"

"Had the whole house insulated in 2016. Just found out that there is now mold in the attic. Have had three different contractors come to look at it and ALL have said the reason is because when the insulation was blown into the attic they did not take the time to rake it away from the soffits. Now I'm faced with a major repair bill of $3000 to eliminate the mold. Plus, to make matters worse, my utility bill did not go down very much after having this done. Only thing I can say is that the house is more comfortable. So beware if you use this company and make sure they install the insulation into your attic correctly!"

Insulation questions, answered by experts

To keep your family and pets safe during insulation service in Delaware, consider arranging for them to stay elsewhere while work is underway, especially if spray foam or fiberglass is used. Opt for low-dust, eco-friendly insulation materials to support better indoor air quality. Ask your contractor to seal off work zones with plastic sheeting, ventilate the area thoroughly, and wait at least 24–48 hours before re-entering, especially during humid Delaware seasons.

Helpful?

In Delaware, most attic insulation projects for a typical home are completed within 1–2 days, while wall insulation retrofits may take 2–4 days. Basement or crawl space insulation usually lasts 1–3 days. Whole-home insulation projects can extend up to a week. Factors like weather, home age, and material availability in Delaware can affect the schedule, so always confirm timing with your contractor.

Helpful?

Insulation service in Delaware can impact your home’s HVAC, electrical, and ventilation systems. Improved insulation may require HVAC adjustments for optimal airflow and efficiency. Electrical fixtures, especially recessed lighting, need proper clearance to prevent overheating. Plumbing in unheated spaces should be insulated to avoid freezing. Discuss these systems with a local professional to ensure your insulation upgrade supports overall home performance.

Helpful?

In Delaware, homeowners often overlook sealing air leaks before installing insulation, which can undermine energy efficiency. Skipping vapor barriers in humid areas or compressing insulation in tight spaces reduces its thermal barrier effectiveness. Blocking attic soffit vents, using the wrong R-value for Delaware’s climate, or attempting DIY spray foam without proper safety gear can also lead to comfort and performance issues.

Helpful?

If you notice rising energy bills, uneven room temperatures, or persistent drafts in your Delaware home, it may be time for insulation service. Older homes—especially those built before 1980—or those with visible moisture or condensation often benefit from upgrades. If your HVAC system runs nonstop or you struggle to stay comfortable during Delaware’s seasonal swings, consider scheduling insulation work in spring or early fall.
