"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"

"Following a MassSave audit, about 6 months ago Hugh's insulated our garage. We were very pleased with their work. When we decided to do additional work and insulate our attic, I called Tom again to arrange for Hugh's to do the work. It went very well. I would definitely recommend them to others."

"I was plagued with recurring ice dams in a few areas of my roof. After investigation, it was discovered that the insulation in a few visible areas was sub-par. Roland came in and quickly spotted the problem areas. He assured me that the could fix these problems immediately. He used a combination of rearranging existing batts, blown-in fiberglass and spray foam to seal the attic space, over the course of two visits. He's extremely personable and always called me back or answered the phone right away."

"Work went great. Hired Chris for two rooms of insulation and some messy clean up and the work was done quickly. I greatly appreciate a contractor who will return calls and be in constant contact. 100% recommended."

"This is the second time I have used MA Design and Construction for a project in my house. Both times were great. For the most recent job, they framed up a partially finished basement, added carpet, leveled the ceiling, added a door and electrical outlets and insulated and painted the walls. The finished product looked great. I have found them super easy to work with - they are always very responsive to any questions that I have and they are great about communicating. I plan to have them do additional work for us in the future."

"From the very beginning and throughout the process, Leo explained everything that we would need to know about roofing, the product and the process. Leo is professional and meticulous. The job was completed in one day with a crew of men who attended to every detail. Leo was present throughout the day overseeing the work. The clean up was done efficiently and the yard looks great. But most importantly, the roof looks fantastic. A job well done!"

We started by trying to find a contractor that could fix our gutters. We needed it to be done very quickly so I had called several people with no luck. Then I found United. Alessandro was amazing and his team is amazing -- especially Jackie. They are always very responsive, professional, dependable and of course their work is top notch/very high quality. They not only did our gutters when I needed them done, but also we went back to them to replace our sump pump, paint inside of most of our house, change the kitchen countertops and backsplash etc.. Alessandro also helped me find other specialists when needed such as shower door installers.. I am very happy that I found them and I will for sure go back to them again.

Insulation questions, answered by experts

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?

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?

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.

Helpful?

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.
