Who We Are

Family-led insulation crews,
still here in year 25.

Lenny Scarola started DreamHome in 1999 to combine connection with craftsmanship. He worked every role on the way up, from sales calls to crew supervision. Nish Patel joined in 2000 and rose from neighborhood field sales to Vice President. Kevin Butler, our General Manager and HAAG Certified Inspector, joined in 2005 and has run every role in the company.

We install Owens Corning blown-in fiberglass, blown-in cellulose, and batt fiberglass insulation across NoVA and MD, paired with air sealing of the attic deck and penetrations, attic insulation removal and replacement when the existing material is compromised, and the ridge and soffit vent installation the system actually requires. Two offices, same crews, same standards. Our Springfield, VA office serves Northern Virginia; our Hanover, MD office serves Maryland.

How We Build

Insulation systems built for the Mid-Atlantic.

Northern Virginia and Maryland attics sit in IECC Climate Zone 4 mixed-humid, where the current code target is R-49. Most pre-2010 homes measure R-19 to R-30 today. We spec the air-sealing scope, the blown-in material, and the ventilation pathway to the roof above and the conditioned space below, not the upsell. Spec R-value is only half the story; air sealing is the other half.

01 / R-VALUE TARGET

R-49 attic target with Owens Corning blown-in fiberglass or cellulose

IECC Climate Zone 4 code minimum is R-49 in vented attics. Owens Corning blown-in fiberglass tops most NoVA + MD attics from a measured starting depth to R-49 cleanly; blown-in cellulose is the call for tight cavities, knee walls, and old homes where settling is a concern. Batt fiberglass for cathedral and rafter assemblies. We measure before we quote and document depth post-install.

Blown-in fiberglassBlown-in celluloseR-49 target
02 / AIR SEALING FIRST

Top plates, recessed lights, plumbing chases, attic hatch sealed before insulation

The Department of Energy estimates 30 to 40 percent of conditioned air leaks through unsealed attic-floor penetrations: top plates of every interior wall, recessed light cans, plumbing chases, HVAC ducts, and the attic hatch. Insulation slows conductive loss; air sealing stops convective loss. Spec R-49 on top of an unsealed deck performs more like R-30 in practice. Air sealing the deck is standard on every DreamHome attic, not an upcharge.

Top-plate sealCan-light sealAttic-hatch seal
03 / INSTALL

Ventilation-aware, paired with the roof above, not stand-alone insulation crew

Attic insulation does not exist in isolation. The ridge and soffit vent path, the roof deck above, the moisture barrier under the deck, and air leakage from the conditioned space all interact with whatever you blow into the attic. The same BPI-Certified energy expert who reads the attic also reads the roof system, then we install. Stand-alone insulation crews never see the roof above and trap moisture under the deck. We do not.

BPI-pairedVentilation awareRoof-system aware
04 / DIAGNOSIS

Existing insulation, moisture, and vermiculite checked before tear-out

Every attic project starts with a read of what is in there now. Clean fiberglass batts or blown fiberglass in good condition can be topped off. Old vermiculite (asbestos concern), insulation contaminated by rodents or mold, water-damaged insulation, or insulation that has settled below R-15 gets removed first. Per-square-foot removal adders are disclosed up front, not as a surprise once the truck is in the driveway.

Vermiculite checkMoisture meterNo Surprises
Five Promises

What we put
in writing.

Customers tell us five things sealed the decision. Each one is a contract clause with a number. If we miss one, we make it right at our cost. Not a marketing line, a contract obligation.

01

Every attic, air sealed first.

Top plates of every interior wall, recessed light cans foam-sealed or IC-rated boxed, plumbing chases sealed, HVAC duct boots mastic-sealed, attic hatch weatherstripped with rigid foam backer. Spec R-49 insulation on top of an unsealed deck performs like R-30. Air sealing is standard, not an upcharge.

02

BPI-Certified building science.

BPI (Building Performance Institute) is the gold standard for whole-home energy work. The audit reads air leakage, ventilation, moisture pathways, and insulation depth as one system. Stand-alone insulation installers do not carry BPI. We do, and every audit is BPI-graded before a single bag of insulation comes off the truck.

03

Hidden moisture, disclosed.

Every attic audit checks for vermiculite (asbestos concern in pre-1990 homes), rodent contamination, water staining on the deck, and insulation that has settled below R-15. We tell you when topping off is the right call and when strip-and-replace is. Per-square-foot removal adders are disclosed up front, not as a surprise once the truck is in the driveway.

04

Neighbors, not storm chasers.

Springfield and Hanover are physical offices, not PO boxes. Same crews on every job. The workmanship warranty stays valid because we are still here in year 15. Storm chasers vanish; we do not.

05

25-year workmanship warranty.

Layered on top of the Owens Corning blown-in fiberglass product warranty (lifetime on the insulation material itself) and any blower-door tested air-sealing scope. Transferable if you sell the home. The full document is in every contract, not a verbal promise.

Services

From a quick attic top-off to full strip-and-replace.

Six service families. Audit first. We tell you when topping off the existing insulation to R-49 buys you another 15 years and when strip-and-replace is the better economic call.

Standard

Attic Insulation Installation

Blown-in fiberglass or cellulose to the R-49 IECC Climate Zone 4 target, layered over an air-sealed deck. The standard call for most pre-2010 NoVA + MD attics measuring R-19 to R-30 today.

Owens Corning

Blown-In Fiberglass (Owens Corning)

Owens Corning blown-in fiberglass is the standard call for open attic floors that need a clean top-off or full re-insulate. Settles less than cellulose, does not absorb moisture, lifetime product warranty. We hit R-49 at a measured depth and document it.

View Blown-In Fiberglass
Dense Pack

Blown-In Cellulose Insulation

Blown-in cellulose for tight cavities, knee walls, dense-pack wall retrofits, and older homes where settling control matters. Higher R-value per inch than fiberglass; treated for fire and rodent resistance. The call for homes built before 1980.

View Blown-In Cellulose
Building Science

Air Sealing

Top plates of every interior wall, recessed light cans, plumbing chases, HVAC duct boots, attic hatch. The single highest ROI improvement to most older NoVA + MD homes; standard on every DreamHome attic project, not an upcharge. Blower-door pre and post test on premium scopes.

View Air Sealing
Strip and Replace

Insulation Removal and Replacement

Vermiculite (with asbestos protocol), rodent-contaminated insulation, mold or moisture-damaged insulation, or insulation settled below R-15. Full strip with HEPA-filtered vacuum, deck sterilized, air sealed, then re-insulated to R-49. The right call when topping off is not.

View Removal
Ventilation

Ridge and Soffit Vent Installation

Continuous ridge vent, soffit vent retrofit, power vent installation, and attic ventilation audit. Without the right intake-and-exhaust ratio, blowing R-49 into a sealed attic traps moisture and accelerates roof sheathing decay. We size the ventilation to the attic, then insulate.

What to Expect

Inspection to install in seven steps.

Most attic insulation projects finish in 4 to 8 hours. Strip-and-replace with full air sealing runs 1 to 2 days. Material lead time is days, not weeks — Owens Corning blown-in fiberglass and cellulose ship from local distribution, and we stock the standard SKUs.

Credentials That Matter

BPI Certified, Roof + Attic inspected together, Owens Corning trained.

Attic insulation is a sub-system of the roof above and the conditioned space below. The credentials worth paying for are the ones that vet exactly that intersection. Stand-alone insulation crews carry none of these. DreamHome carries all five.

DreamHome reads the attic system together with the roof system because that’s where most insulation problems actually live. Burke mainstream colonial with high summer cooling bills despite spec R-49? Almost always an air-sealing problem, not an R-value problem. Reston cedar-shake home with ice damming at the eaves? Almost always a ventilation + insulation-baffle problem, not a roof problem. We tell you what is actually wrong, not what is easiest to sell you.

Material Choice

Blown-in fiberglass vs Blown-in cellulose: which makes sense for your attic?

Both work; both hit R-49 in a NoVA + MD attic. Owens Corning blown-in fiberglass wins on settling control, moisture resistance, and clean install. Blown-in cellulose wins on R-per-inch density and tight cavities, knee walls, and dense-pack retrofits. We spec both; the audit tells us which is right for your attic.

Older Anne Arundel home with prior settling and a rodent gap that needs both removal and dense fill: blown-in cellulose with HEPA-vacuum strip first. The audit tells us which conversation to have.

Local Reality

What changes when you re-insulate in a NoVA or MD home.

Five region-specific things that matter here and rarely show up on contractor websites that aren’t this local.

Northern Virginia

Fairfax County tax credits and utility rebates, handled.

The federal Section 25C Energy Efficient Home Improvement Credit refunds 30 percent of insulation and air-sealing costs up to $1,200 per year through 2032. Dominion Energy and Washington Gas run additional residential rebate programs on attic insulation and air sealing for qualifying homes. We document the work to the IRS Form 5695 standard and to the utility rebate standard, so the credit is straightforward to claim. Most contractors do not.

Northern Virginia

Why Reston and Burke Centre attics aren’t simple.

Reston and Burke Centre 1970s townhomes commonly have cathedral ceilings, knee walls, and spec R-19 attic insulation that does not meet today’s R-49 code minimum. The cathedral ceilings cannot just be topped off, the knee walls need dense-pack cellulose, and the attic floor needs air sealing before the blown-in goes in. A stand-alone insulation crew that quotes “blow R-49 across the attic floor” misses two-thirds of the actual work. We do the BPI-graded audit and quote the full scope.

Attic InsulationSpringfield Office
Maryland

Why Maryland coastal attics need different specs.

Anne Arundel sits in a different humidity envelope than Frederick or Carroll. Chesapeake Bay summer humidity loads more moisture into the attic than inland MD, and the freeze-thaw cycle on the bay side drives ice-dam moisture intrusion at the eaves. Owens Corning fiberglass (does not absorb moisture) generally outperforms cellulose in coastal attics. Ventilation gets sized for the higher moisture load, not the inland default. We spec to your ZIP code.

Hanover Office
Pre-1990 Homes

vermiculite insulation, identified before we touch it.

Pre-1990 homes occasionally have vermiculite (gray-brown pebble-like material) in the attic. Most vermiculite from that era is from the Libby, Montana mine and is contaminated with asbestos. We identify vermiculite in the free audit BEFORE any work begins. If present, we sub the removal to a licensed abatement contractor (legal requirement), document the removal, then return to air seal and re-insulate to R-49. Most stand-alone insulation crews blow over vermiculite without identifying it. We do not.

Verify your Maryland insulation contractor in 30 seconds.

Maryland uses an MHIC license, not a contractor tier like Virginia’s Class A. Verify a contractor’s MHIC at labor.maryland.gov/pq. Our MHIC is #86946. If a contractor can’t produce a current MHIC, walk away. If they say “we’re licensed in Virginia,” walk away faster. VA Class A does not cover MD work.

Hanover Office
Cost Transparency

What attic insulation costs in NoVA and MD.

Per-home installed. Pricing depends on attic square footage, starting R-value, blown-in material (fiberglass vs cellulose), air-sealing scope, and whether vermiculite or contamination triggers full removal first. Free audit determines the right tier for your attic. Section 25C federal tax credit refunds 30 percent (up to $1,200 per year) on qualifying scopes.

Top-Off

Attic Top-Off or Small-Area Blown-In

$800–$1,800

Topping off an attic from R-19 or R-30 starting depth to R-49 IECC Climate Zone 4 code with Owens Corning blown-in fiberglass or cellulose. Includes light air sealing of the most visible penetrations. The right call when the existing insulation is clean and the attic floor is reasonably sealed already.

Standard

Full Re-Insulate + Air Sealing

$1,800–$4,500

Air sealing of top plates, recessed light cans, plumbing chases, HVAC duct boots, and attic hatch FIRST, then blown-in to R-49. The standard call for most NoVA + MD pre-2010 homes. Section 25C eligible. Most ROI per dollar of any insulation scope.

Premium

Strip-and-Replace + Ventilation Rework

$4,500–$12,000

HEPA-filtered removal of contaminated, settled, vermiculite, or rodent-fouled insulation. Deck sterilized. Air sealing. Ventilation rework (ridge vent install, soffit vent retrofit, baffle replacement). Then blown-in to R-49. Blower-door pre and post test. The right call for older homes with prior moisture or contamination issues.

“They walked the roof system AND the attic during the audit and flagged two recessed-light cans that were leaking heated air straight up. Air sealed those first, then blew Owens Corning to R-49. Upstairs bedrooms went from unusably hot in summer to comfortable. The quote was the price, no surprises.”

“We had three contractors quote attic insulation. DreamHome was the only one who pulled out a moisture meter and explained that our existing R-19 was actually performing more like R-12 because of unsealed top plates. They air sealed first, then re-insulated. Best contractor experience we’ve had.”

Insulation FAQ

Insulation questions NoVA and MD homeowners ask.

What R-value should my attic be in Northern Virginia or Maryland?
Northern Virginia and Maryland sit in IECC Climate Zone 4 (mixed-humid), where the current code target for vented attics is R-49. Most homes built before 2010 in NoVA and MD measure at R-19 to R-30 today, meaning a homeowner who tops off to R-49 typically recovers 10 to 30 percent of their heating and cooling load. Spec R-value is only half the story though. Air sealing the attic deck and penetrations BEFORE adding insulation often delivers more comfort and lower bills than thicker insulation alone, which is why every DreamHome attic project starts with air sealing, not just blowing in more fiberglass.
Is the free attic audit really free?
Yes, 100% free with no obligation. The same BPI-Certified energy expert who reads the roof system above also reads the attic deck, the existing insulation depth, the air-sealing condition, the ridge and soffit vent pathway, and any moisture or rodent damage in the existing insulation. Written findings report with photos within 24 hours. No invoice if you do not move forward.
Why does a roof contractor doing insulation matter?
Attic insulation does not exist in isolation. The roof above, the ridge and soffit vent path, the moisture barrier under the deck, and the air leakage from the conditioned space all interact with whatever you blow into the attic. Stand-alone insulation contractors who never see the roof system can install fine-looking R-49 fiberglass on top of an attic that is trapping moisture under the deck, accelerating sheathing decay and shortening the roof life by years. Every DreamHome insulation project is graded by a BPI-Certified inspector AND paired with the roof system inspection. Most stand-alone insulation installers will not do that work because it is not in their scope.
Should I remove old insulation, or just blow on top?
Depends on what is in the attic now. Clean fiberglass batts or blown fiberglass in good condition can usually be topped off with additional blown fiberglass or cellulose to hit the R-49 target. Old vermiculite (concern for asbestos), insulation contaminated by rodents or mold, water-damaged insulation, or insulation that has settled to under R-15 should be removed first. We audit the existing insulation during the free attic inspection and recommend top-off or removal-and-replace explicitly. The contract calls out the per-square-foot removal rate up front, so the typical “we found contamination, that is another $1,200” surprise does not happen.
Does air sealing matter if I am already adding R-49 insulation?
Yes, dramatically. The Department of Energy estimates a typical Mid-Atlantic home loses 30 to 40 percent of its conditioned air through unsealed attic-floor penetrations: top plates, recessed light cans, plumbing chases, attic hatch, HVAC ducts, and the wire and pipe holes drilled through the top plates of every interior wall. Insulation slows conductive heat loss; air sealing stops convective heat loss. Spec R-49 insulation on top of an unsealed attic deck performs more like R-30 in practice. Air sealing the deck before insulation install is standard on every DreamHome attic project, not an upcharge.
Do you handle insurance claim documentation for storm-damaged or moisture-damaged insulation?
Yes. Wind-driven rain damage, ice-dam soak-through, roof leak penetrations, and rodent contamination from an unrepaired soffit gap all qualify for insurance review. Our HAAG-certified inspector produces written findings adjusters use directly. We work alongside State Farm, Allstate, USAA, Erie, and Virginia Farm Bureau. We do not negotiate the claim itself, that requires a public adjuster license.
Do you serve my city?
Yes if you’re in our NoVA or MD service territory. NoVA (served from our Springfield, VA office): Fairfax County, Arlington, Alexandria, Loudoun, Prince William, Stafford, Fauquier. MD (served from our Hanover, MD office): Anne Arundel, Howard, Montgomery, Prince George’s, Baltimore, Frederick, Carroll counties. Full city list in the link cluster below.
