"Andrew and his crew did an excellent job! They provided all the insulation (dense pack cellulose, spray foam, etc) for our large 2 story addition. They were on time and on budget. In fact, even when Andrew realized he had inadvertently overlooked a part of the job in the initial quote, he let us know immediately about the oversight (before we finalized the contract) and he went above and beyond to still keep his word (and the initial price). Andrew was great at communicating with us about arrival times, etc. He kept us in the loop on everything. He and his crew worked diligently until the job was done, which took about 6 days. They were polite and professional. They kept the job site clean. They were very detail oriented, and we truly felt they wanted to do the best job possible. Andrew is very knowledgeable about insulation ......and cost competitive. We HIGHLY recommend Coastal Insulation for all your insulation needs!"

Insulation FAQs, answered by experts

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

When installing metal siding, a high-quality house wrap is considered the best protection against condensation and moisture infiltration. House wraps can increase a home's efficiency significantly. However, a house wrap is not a replacement for a vapor barrier because it can be permeable when moist air passes through siding. This is why it's essential to follow manufacturer instructions for insulating siding when installing new siding.

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

Insulation prevents heat transfer, which keeps your home cool in summer and warm in winter. Regulating the temperature in your home is not only more comfortable for you, but will lower your heating and cooling bills—it’s a win-win. Make sure to determine the correct amount of insulation to ensure it is enough for your home and climate.

Heavily exceeding building code requirements for insulation not only wastes money on materials but can also lead to ventilation and moisture problems. In most cases, the minimum amount of insulation required by code is perfectly adequate.
