Our Attic Insulation Services

Winner Insulation provides a full array of attic insulation services in Maryland, Northern Virginia, and Washington, DC.

  • Energy Audits

Our home energy audit service identifies where your home is leaking energy and where your home’s insulation gaps are.

  • Seal Attic Air Leaks

We eliminate gaps and holes that allow air to flow from your attic to other living spaces in your home. This produces a thermal barrier that prevents heat transfer into and out of the attic once your insulation is installed.

  • Attic Insulation Removal

If you need a contractor to remove insulation from your attic, we can help. As part of our attic insulation price estimate, we will determine if you need to remove old attic insulation before installing new insulation.

  • Installing Attic Insulation

We install a variety of attic insulation styles, including spray foam insulation, pre-cut insulation batts, insulation rolls, spray foam insulation, and more. We’ll select the right insulation material for your home – fiberglass, cellulose (recycled paper), or foam.

  • Attic Ventilation

Proper attic ventilation helps prevents heat buildup during summer months and allows warm, moisture-filled air to escape during cool months. We partner with experienced ventilation contractors to install attic ventilation as need with attic insulation projects.

Benefits of Installing Attic Insulation

If your home’s attic doesn’t have insulation – or if the insulation has thinned over time – installing new attic insulation can improve energy efficiency and provide other benefits. Below are some of the advantages of insulating your attic:

  • Increase Your Home’s Comfort:Adequate attic insulation helps keep temperatures stay consistent from room to room throughout your house.
  • Lower Your Utility Bills:In the Washington, DC metro area, more than 40% of home energy costs are from heating and cooling. Installing attic insulation can reduce your home’s heating and cooling costs.
  • Reduce Your Carbon Footprint: By reducing the need for your furnace or air conditioner to run, attic insulation lowers your home’s environmental impact.
  • Prolong Your Furnace and AC Life:The less frequently your AC and furnace need to run, the longer they’ll last.
  • Reduce Home Repair Costs: Attic insulation helps protect against water vapor, which can damage walls. It defends against attic heat buildup, too, which can cause shingles to crack.
  • Improve Your Home’s Indoor Air Quality:Airborne particles like pollen, dust, and mold circulate in your home air and ducts. Air leaks caused by inadequate insulation can allow these airborne pollutants to enter your home.

Attic Insulation Materials

The most common insulation materials are fiberglass, cellulose, and foam. Each offers its own advantages for Maryland and Virginia homes:

  • Fiberglass Attic Insulation:Fiberglass is an affordable insulation choice – in fact, it’s often the most cost-effective attic insulation Along with its low installation cost, fiberglass provides excellent thermal performance and sound dampening qualities.
  • Cellulose Attic Insulation:The superior thermal resistance of cellulose makes it an ideal attic insulation material for Washington, DC- and Baltimore-area homes. Cellulose insulation also reduces solid waste, since it’s made of recycled paper.
  • Foam Attic Insulation: Spray foam insulation is effective in sealing roofs and attics, where condensation tends to accumulate the most. It provides an airtight seal and provides strong moisture resistance.

Attic Insulation Types

The right type of attic insulation for Mid-Atlantic homes depends on which type is currently installed and the R-value required for your home. Common types of attic insulation include loose-fill, spray board, batts, rolls, foam board, and vapor barriers.

Below are some of the types of insulation we install in Northern Virginia, Maryland and Washington, DC attics:

  • Loose-Fill Attic Insulation. Fiberglass or cellulose loose-fill insulation is easily blown or sprayed into hard-to-reach places like your attic. It’s also a good option for installing over existing insulation.
  • Attic Insulation Batts. These pre-cut sections of insulation are installed easily between the framing studs and joists in your attic.
  • Attic Insulation Rolls. These are ideal for attics, where long rolls of insulation at pre-cut widths can be run between studs and joists.
  • Foam Board Attic Insulation. Versatile foam insulation boards can be used almost anywhere in your home, including the attic. They reduce heat conduction through wood, steel studs, and other structural elements.
  • Spray Foam Attic Insulation. Ideal for sealing around doors, windows, and vents, spray foam insulation is often used to fill small gaps and cracks.
  • Attic Vapor Barriers. Vapor barriers help control moisture buildup that can reduce your insulation’s R-value and cause mold or rot.

DIY Attic Insulation vs. Hiring an Insulation Professional

Many homeowners attempt DIY attic insulation as a cost-saving measure. While we understand the impulse, there are risks associated with installing attic insulation yourself, including:

  • Failure to seal attic air leaks
  • Failure to fix roof leaks
  • Fire hazards due to improper installation
  • Improper attic ventilation
  • Health and safety risks during installation
  • Improper installation leading to future problems

Factors that affect attic insulation costs in Maryland and Virginia include the insulation material (fiberglass, cellulose, etc.), insulation type (batts, rolls, spray-in, etc.), R-value, and square foot coverage area.

Frequently Asked Questions

How much insulation does my attic need?

The answer is a simple formula: How many square feet is your attic, and what R-value do you need? We can provide a quick estimate with a phone consultation – call us at (800) 955-1976.

Do I have to remove attic insulation before installing new insulation?

It depends. In some cases, you can add new attic insulation on top of existing insulation, essentially boosting your home’s thermal envelope. However, you may have to remove existing attic insulation if it’s damaged or mold is present, or if the material isn’t suitable for keeping in place when adding new insulation.

Does attic insulation soundproof my home?

While insulating your attic won’t completely soundproof your home, it does provide sound-dampening qualities to reduce in-home noise from traffic, construction, or loud neighbors.

Can you put too much insulation in your attic?

Many DIY attic insulation attempts result in too much insulation. You could be obstructing attic vents and fans, reducing airflow, and preventing moisture removal in your attic. To avoid over-insulating your attic, it’s best to consult a professional installer.
