Why Baltimore homes are different

Insulation for Older Baltimore Rowhomes & Single-Family Homes

Much of Baltimore's housing was built long before modern insulation standards. Many homes still have thin, compressed or patchy insulation, several layers of old material added over the decades, and air leaks around chimneys, plumbing and wiring. Rowhomes often have tight, low attic spaces with limited access, while detached homes in neighborhoods across the city may have full attics or crawl spaces that have never been properly insulated.

That's why we don't quote from a chart. Every Baltimore City project starts with an inspection of the actual space, so the recommendation fits the home in front of us, whether that's adding insulation, removing old material first, or sealing air leaks before anything new goes in.

What we do

Insulation Services in Baltimore City

Insulation Installation

We install blown-in fiberglass, cellulose and batt insulation based on the home, the existing insulation and the recommended R-value. Proper insulation helps reduce heat transfer and keeps upper floors more comfortable year-round.

Insulation Removal

Old, wet, compressed or contaminated insulation often needs to come out before new insulation goes in. Our vacuum equipment removes loose-fill insulation and debris into sealed collection bags, keeping dust out of your living space.

Air Sealing

Gaps around chimneys, plumbing, wiring and framing let conditioned air escape. We seal accessible openings before installing new insulation so it can perform the way it should.

Learn more about attic air sealing

Attic Cleaning

Debris, old material and contamination left behind in an attic can be cleaned out with HEPA or heavy-duty vacuuming and sanitation, preparing the space for new insulation.

Crawl Space Insulation

Missing, sagging or fallen crawl space insulation can mean cold floors and higher energy bills. We remove damaged material and install new insulation suited to the space.

Crawl Space Encapsulation

For damp crawl spaces, we clean out old material, install a heavy-duty reinforced liner, seal openings where appropriate and add humidity control when the space needs it.

Our core service

Attic Insulation Removal in Baltimore

Older Baltimore attics often hold decades of insulation layered on top of each other, along with dust, debris and moisture damage. Removing it is often the first step toward a better-performing attic. Homeowners usually call us after noticing:

  • Old, flattened or deteriorated insulation
  • Water-damaged insulation from a past roof leak
  • Musty odors coming from the attic
  • Droppings or nesting material in the insulation
  • Uneven temperatures and high energy bills

We remove the old material, clean the space when included, seal accessible air leaks and install new insulation to the agreed R-value. Not sure you need removal? Read whether new insulation can go over old.

Contaminated insulation

Rodent-Contaminated Insulation Removal & Replacement

When mice, rats or squirrels have been living in an attic or crawl space, the insulation is often left full of droppings, urine and nesting material. Rodent-contaminated insulation may contain droppings, urine, nesting material and debris, and can hold persistent odors.

As part of an insulation project, Xanvria removes the contaminated insulation, cleans and sanitizes the space, seals accessible entry points in the attic or crawl space, and installs new insulation.

Please note: we are an insulation contractor, not a pest control company. We don't trap or exterminate rodents or seal openings in living areas such as kitchens. If you have active rodents, contact a pest control professional first, then call us to restore the insulation.

Crawl spaces

Crawl Space Insulation & Encapsulation in Baltimore

Baltimore's humid summers can make crawl spaces damp, leading to musty smells, condensation, sagging insulation and cold floors above. Depending on what we find, the right solution may include:

  • Crawl space cleaning and removal of old plastic and fallen insulation
  • A heavy-duty vapor barrier over exposed soil
  • Air sealing and crawl space insulation
  • Full encapsulation with humidity control when needed

If we find significant mold, we'll recommend an independent mold remediation specialist before encapsulation. See our crawl space encapsulation process.

Yes. Xanvria provides attic insulation, insulation removal, air sealing, attic cleaning, crawl space insulation and crawl space encapsulation throughout Baltimore City and surrounding Maryland communities.
