Coastal Insulation does insulation work, and a 2019 customer said it provided all the insulation, including dense pack cellulose and spray foam, for a large two-story addition, a job that took about 6 days. That 2019 customer said Andrew realized he had overlooked part of the job in the initial quote, told them before the contract was finalized, and kept the initial price. A 2020 customer wrote that Andrew and his crew installed RockWool batts in the attic of an older home over a couple of hot summer days, getting the bags through a small trap door in a second-floor bathroom and fitting the batts to irregular joist bays. That 2020 customer said the bags went up the front stairway without scuffing the walls. A 2019 customer said the job was done before Christmas, leaving the home warm for the holidays. A 2019 customer described being in and out in about 3 hours on insulation work that needed quite a bit done. A 2020 customer said the work was finished in one day and the work area was left clean. A 2019 customer said Andrew reviewed the details of the job with them, charged a reasonable price and thoroughly cleaned the work area once the work was completed. On both Angi and HomeAdvisor, the company shows 4.9 stars from 21 ratings. A 2020 customer said they had no diagnostic tools to evaluate the job but believed the furnace was cycling less.
The time it took them to start the job was very short. They arrived when they said they would, were very courteous, left the area of work clean, finished in one day, and did an excellent job.
Andrew and his crew did great work on a tough job at a competitive rate. They installed batts of RockWool in our attic over a couple of hot summer days, carrying big bags of it up our front stairway without scuffing the walls and then getting it through the small trap door in our second floor bathroom into the attic and laying it tightly in overlapping, crisscrossed layers from there. We have an older home and the joist bays are all irregular, requiring careful trimming and fitting of the batts in the ceiling plane. Prompt service, too. I am very appreciative of their work.
Great crew! Great communication and got the job done fast!Katharine k P.
