Its website describes insulation work for homes and commercial properties across Massachusetts, names Northborough as its service area, and says the business has been operating for 6 years. 4 Season Shield Corp. holds Massachusetts home improvement contractor registration 218977, active on the state registry. A 2025 customer said the company's foam spray insulation work was completed on time, that the crew did a clean and neat job and cleaned up thoroughly when finished, and that the pricing was fair. A 2025 reviewer who works as a small general contractor said there was a language disconnect, but they had a phone app to translate from Brazilian to English and it worked out fine; that reviewer said they were on time and did a good job. A 2022 customer said scheduling with Helter was easy and prompt, and that Helter came out the next day to make sure the customer was happy with the job. In a 2021 review, Whiting Builders Inc., a custom builder, called Helter a trusted partner for all of its insulation needs and said he and his crew were clean in their work and competitively priced.
I was very impressed with the foam spray insulation service. The work was completed on time, and the crew did a remarkably clean and neat job. They made sure to clean up thoroughly once they were finished, which was a huge plus. The pricing was very fair, and I would definitely recommend this company to anyone.
There was a language disconnect but they had an app on their phone to translate form Brazilian to English and it worked out fine. I'm a small general contractor for over 20 years and will use them again. They were professional, on time and did a good job.
Perfect quality!
Working with Helter was awesome! Scheduling was easy and prompt, the work was done professionally and quickly, Helter even came out the next day to make sure I was happy with the job 😊
Helter and his crew from 4 Season Shield Insulation, do an amazing job for us.

They are very clean in their work and prompt in getting to the project when they say they will. Also, very competitively priced. Mike Whiting Whiting Builders Inc.
