"We called Home Seal to consult on weatherization and insulation for our 1920s bungalow. The advice was great and we hired them to insulate the rim joists between our basement and first floor as well as adding cellulose insulation to our attic space. The communication throughout this project went well and the work was completed as scheduled. We would highly recommend Home Seal for weatherization and insulation projects."

"Ryan, Miguel, Luis and staff did a great job removing old insulation, inspect, clean & disinfect, spray foam, and blow in new insulation. They were efficient, kept me informed, cleaned up well, and addressed minor issues after the completion was complete. I had planned to also spray foam the basement, but we could not vacate the house (fumes) with a member in hospice. This will be done as soon as we are able. Highly recommended!"

"I could not be more impressed with Jesse and his team. They were so responsive, so professional, and so incredibly helpful. Great communication throughout. Great work product. Pricing that was very competative and reasonable. The next time I have an insulation need I won't even both to get bids from other shops. I will just use Century. Highly recomend."

"Carl was very prompt with calling me back and actually arranged to fit me in a day earlier than planned. The work was all completed within a couple hours. I guess I expected the spackling to be all set to repaint over, but that will require some touch-ups before painting. Overall, great experience and we will use Specialty Insulators again when we require this type of project."

Insulation questions, answered by experts

Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don’t pose risks for fiberglass exposure because they're fully encased in polymer cladding.

The primary downside of radiant barriers is their limited effectiveness in cold climates. They are designed to reflect radiant heat, making them less beneficial in cooler conditions where heat retention is more important. 

Radiant barriers require proper installation to maximize effectiveness. Incorrect placement can lead to minimal benefits. They also do not provide insulation, meaning they should be used in conjunction with traditional insulation for optimal energy efficiency. 

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.
