"We decided to install insulation in the attic and crawl space a couple of months ago. We got an estimate from Mike and two other companies but he offered us the most competitive deal. Mike and his crew showed up on time, installed the insulation and cleaned up after the job was done. Communication was excellent throughout the entire process. We highly recommend Handyman Insulation for this kind of work."

"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."

"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

Insulation questions, answered by experts

After completing an insulation service project in Wilmington, schedule a walk-through with your contractor to verify that all attic insulation and wall insulation are properly installed and sealed. Track your home’s energy bills for noticeable changes in efficiency. Check for any drafts or uneven temperatures in living spaces, and inspect for signs of moisture or settling in newly insulated areas. Keep all service records and warranty paperwork organized for future reference.

Helpful?

Completing an insulation service project in Wilmington enhances home comfort by stabilizing indoor temperatures, reducing drafts, and improving air quality. Proper insulation minimizes outside noise and helps control humidity, which is especially important during Wilmington’s humid summers. You’ll experience fewer cold spots in winter and less heat intrusion in summer, making your home more energy efficient and consistently comfortable year-round.

Helpful?

To establish a seasonal inspection routine in Wilmington, start each spring by checking attic insulation for winter moisture or damage. In summer, monitor crawl spaces for excess humidity. Inspect air sealing and vents in the fall to prepare for colder months, and during winter, look for cold spots or ice dams. Monthly, note any unusual odors or changes in energy use to catch insulation issues early.

Helpful?

In Wilmington, insulation maintenance involves checking attic insulation for compression, ensuring crawl spaces remain dry, and inspecting for pest intrusion, especially after heavy rain or seasonal changes. Look for gaps or damage in insulation materials, and confirm that ventilation is unobstructed to prevent humidity buildup. Scheduling a professional assessment every few years helps maintain home efficiency and prolongs the lifespan of your insulation.

Helpful?

In DE, the short-term benefits of insulation service include immediate improvements in home efficiency, reduced drafts, and better temperature control. Over time, you’ll notice increased property value, a healthier indoor environment with less risk of mold or pests, and lower maintenance needs. Enhanced insulation also supports quieter living spaces and contributes to a reduced environmental impact, making your home more comfortable and resilient for years to come.
