He was quick, efficient, and reasonable. His bid to install was way cheaper than the three other options I was given. Highly recommend.

We had called two other installers before we looked for someone on Angi. Both previous installers said they would call with a time to schedule the project and they never called us back. Architectural Insulation was great in their communication, price quote, punctuality, and quality. So glad we...

We initially hired C&W to install vinyl plank flooring throughout the house, but they did such a great job (for a reasonable price, I might add) that we had them come back to perform storm-damage repairs to the house and replace the six foot privacy that was lost. The work was timely, and the...

Doorbell Installation FAQs, answered by experts

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.

Natural fiber batts and spray foam insulation both work great for soundproofing. Newer materials, such as hemp batts, are more expensive but more effective for insulation and sound blocking. They are also more sustainable. There is also a professional system called Blow-In Blanket Insulation (BIBS) that is soundproof and moisture-resistant. However, BIBS must be installed professionally and can be a costly investment.

Yes, winterizing your mobile home is helpful for your safety and savings. Keeping your mobile home safe, secure, and warm during the winter will protect it against damage from harsh weather, which can lead to expensive repairs. Not only that, but winterization also helps to lower your energy bills by keeping warm air in and cold air out.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.
