"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

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home’s existing insulation, you have a higher-than-average square footage, or accessibility is limited.

Monolithic slabs don’t require insulation, but many homeowners choose to have their contractors install insulation under the slab during construction. This can help improve home efficiency even more and keep indoor temperatures more stable. Slab foundations are more energy-efficient than uninsulated crawl spaces and basements, and insulated slab foundations are more energy-efficient than insulated crawl spaces and basements.

For a DIY solution to protect an outdoor faucet from freezing, you can craft a cover using spare rags, a durable plastic bag, and duct tape. However, be aware that this method may not be as effective as a store-bought cover. Fabric like rags or old towels can absorb water, which could freeze and cause problems. While a DIY cover can work as a temporary stopgap, a proper outdoor faucet cover is inexpensive (often $5 or less), easy to install, and readily available, making it the recommended long-term solution.

Yes, insulating your cold water pipes is a great way to prevent condensation. When warm, humid air meets cold pipes, condensation forms, which can drip and cause moisture issues in your home. Pipe insulation acts as a barrier between the warm air and the cold pipes, keeping condensation at bay and helping you avoid potential problems like mold or structural damage.
