I needed a handyman to temporarily install a protective cover on a window so the local electrical company could install a new line next to it. Work was done quickly and on time. Great communication and good price. Will definitely use them again!

Doorbell Installation questions, answered by experts

Yes, professionals install and upgrade insulation for all home or business areas.

The time required for insulation installation can range from a few hours to a few days, with most projects taking 1-3 days to complete. The final duration depends on the project's size and complexity, the area size, and the type of insulation being installed.

Reflective and high R-value batt or roll insulation are often considered energy-efficient, offering significant thermal resistance benefits.

Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated.

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together.

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.
