BP Insulation is an excellent company. They were responsive and answered all my questions, making me feel at ease. They did a very good job with the sound insulation and did it quickly. My tenants in both suites are very happy. They also recommended improving the attic insulation and ventilation, which helped improved the stability of temperature differential in summer and winter inside the house. They go the extra mile to help the customers and follow thru in completing the job. You are in good hands. They are well experienced.
