"Jacob and his team were great ! Everyone was super nice. I felt very comfortable in what I was told in regards to what needed to be done. After talking to many different insulation companies this was the only one that knew what I needed done and was able to do it at a great pirce. They managed to finish same day which was amazing. The results are so nice ! We didn't know what to expect as the end result since this is my first time dealing with insulation problems. But everything looks great !! I will definitely be going to them for any future projects. A million thanks to them ! I highly recommend these guys for your insulation needs. A trustworthy and hard working company."

"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"

"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."

"We had a serious water heater leak throughout 4 rooms. Rick had the floor dismantled and replaced - better than it had been originally. The original installers had not staggered the planks — he did and the floors look better than ever. Rick and the men who did the work couldn't have been more professional while getting the job done!! So happy with the results that I would definitely hire Rick again for any future work needing to be done!"

FAQs for insulation service projects in Worcester, MA

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
