"Installation of insulation went well; EZinsul was very thorough. However, there were some clumps of insulation and a thick film of fiberglass covered everything, despite their sweeping up to â industry standardsâ . Jacob & I talked; he came back and dusted to my satisfaction. I appreciated this attention he paid to my project. I would highly recommend EZinsul. Ruth Ann White"

"Insul-Kings is wonderful to work with. They called in the morning to narrow the arrival time, which is very considerate. Nate and his crew arrived on time and CRANKED like a well oiled machine. I have a 4' crawl space. You can barely crouch. No problem! That's why God invented knee pads. They foamed and installed the insulation like it was their own home. It was a work of art. and came out better than I imagined. They patiently indulged my "old man" inquisitiveness. The crew represented Insul-Kings very well. I highly recommend them. This was done through the Mass Save program. So the $2100 job only cost me about $500.00"

The quality of the installation was excellent, and the difference was noticeable immediately. Everything was left clean and organized after the job was done. Highly recommend to anyone looking for top-quality insulation work."

"Oscar and Kevin worked their butts off for 2 days to complete 1900 Sq ft of attic insulation. They were professional, friendly courteous and very knowledgeable about their trade. They explained everything that they did. When completed everything looked great and they cleaned everything up, you'd never have known they were here for 2 days. I highly recommend and would definitely hire them again, great job guys!"

"Clean Tech Construction was terrific! The team arrived slightly before the scheduled time, removed the old, poorer quality insulation, installed new insulation, including areas that a previous company had not been able to reach, and cleaned up everything before they left for the day. When I initially contacted them about the work, they answered my phone calls within 15 minutes and continued to respond to any calls/questions quickly and politely. I would hire them again in a heartbeat."

"Called and asked if they could come by 2 hours earlier than scheduled, which of course I said yes. They put tarps down on the ground to catch debris, and started working. Everything was done in a few hours, they cleaned up, and left. Walking around the house couldn’t tell that any work had just been done. New pipe collars and chimney flashing look fantastic. Perfect match to existing shingles where replacement was necessary."

Insulation questions, answered by experts

Insulation in Worcester homes should be checked each fall for rodent activity and each spring for moisture or ice dam issues, especially in attics and basements. Reapply caulk to air leaks after freeze-thaw cycles, inspect vapor barriers for damage, and clear attic vents of debris. Homes with fieldstone foundations or older framing need extra attention to prevent moisture buildup and maintain energy efficiency.

Helpful?

In Worcester, insulation longevity depends on proper moisture control, thorough air sealing, and using the right R-values for local climate conditions. Choosing closed-cell spray foam for damp basements and dense-pack cellulose for irregular wall cavities is ideal. Professional installation is especially important in historic homes. Scheduling projects between spring and late fall and addressing pest prevention will help your insulation perform efficiently for years.

Helpful?

For insulation maintenance in Worcester, keep a roll of 6-mil vapor barrier plastic, heavy-duty moisture barrier tape, caulk for sealing gaps, and weatherstripping for windows and doors. An infrared thermometer helps identify cold spots, while a portable dehumidifier is useful for basements. Work gloves, dust masks, a staple gun, and a bright flashlight are essential for safely inspecting and maintaining attic or basement insulation.

Helpful?

In Worcester, most attic, wall, or basement insulation service projects in typical homes are completed within one to three days. Whole-house retrofits, especially in Worcester’s historic homes with unique framing or plaster walls, may take three to seven days. Seasonal weather, such as winter storms or high humidity, can add extra time, so plan for flexibility during insulation installation.

Helpful?

Worcester homes built before 1980, especially those with original plaster walls or single-pane windows, often benefit from insulation upgrades. Signs include high heating bills, persistent drafts near floors or windows, uneven room temperatures, or visible ice dams. If your HVAC system runs constantly in winter or you notice basement dampness, your home likely needs improved attic or basement insulation for better comfort and efficiency.
