Adding insulation is one of the most important things to improve your home’s energy efficiency. There are different types of insulation, and the best type for your attic depends on several factors, including climate, budget, and whether you plan to finish the space.

Good ventilation is essential in any attic, as it helps keep the space cool in summer and prevents moisture buildup that leads to mold and other problems. If you’re finishing your attic, you’ll need to ensure enough ventilation to comply with building code requirements.

Structural Integrity:

Before finishing an attic, it’s essential to check for any potential structural issues that need to be addressed. This may include ensuring the roof is adequately supported, fixing any cracks or gaps in the attic floor, and installing rafters or trusses.

Fire Protection:

If your attic is utilized as a living space, it’s essential to ensure it’s appropriately fire-protected. This may include installing a fire-rated ceiling, installing smoke detectors, and creating an escape plan in case of a fire.

If you’re finishing your attic, you’ll need to ensure adequate access to the space. This may mean adding a staircase or ladder or widening an existing doorway.


Attics can be dark and dreary, so adding some light fixtures is essential to make the space more livable. This may include installing a skylight or adding ceiling lights.


An attic can be a great place to store extra belongings, but it’s important to have adequate storage space. If your attic is cramped, consider adding some shelves or cabinets.

Building code requirements:

Before finishing your attic, check with your local building department to see what code requirements need to be met. This may include things like proper ventilation, fire protection, and access.

HVAC system upgrade:

If you’re using your attic as a living space, you may need to upgrade your HVAC system to accommodate the additional space. This may include adding more insulation, upgrading ductwork, or increasing the capacity of your furnace or air conditioner.

Electrical Work By a Licensed Electrition

Adding additional electrical work to the attic can be tricky and dangerous, so calling in a professional is best. A licensed electrician can help you add new wiring, outlets, and light fixtures to make the space more usable. The cost of this work will vary depending on the size and complexity of the project.

What’s Cheaper, Finish an Attic or a Basement?

The cost of finishing an attic or a basement will vary depending on the size and complexity of the project, but generally, it is cheaper to finish an attic. This is because basements typically require more work to make them livable, such as waterproofing and adding egress windows. However, the final remodeling cost will depend on the specific features you want to add to the space.

When deciding whether to finish an attic or a basement, it’s important to consider the purpose of the space. An attic may be a better option if you’re looking for extra living space because it’s typically easier to convert into a livable space. However, if you’re looking for storage space or a place to put a home office, a basement may be a better option.

Our bathrooms were dated back to the 1980's and we needed them redone badly. Johnny did an excellent job meeting our needs and making sure we got everything we wanted in the bathrooms. In the end the bathrooms were exactly what we wanted.
