Attic Air Sealing & Insulation, Crawlspace Encapsulation
Two-phase project covering unconditioned attic and vented crawlspace. Phase 1 — Attic: Air seal attic floor prior to insulation installation: foam all top plate gaps, seal around all recessed light cans (IC-rated boxes to be confirmed before sealing; non-IC cans to be boxed out and sealed per code), foam around plumbing and electrical penetrations, seal pull-down stair perimeter with weatherstrip gasket and rigid foam cover. Remove existing blown-in fiberglass insulation (approximately 4 inches, estimated R-13 based on visual assessment — actual depth to be confirmed at start). Existing insulation shows signs of wind-washing near soffit baffles; removal allows direct inspection of attic floor for any moisture damage before new insulation is placed. Install blown-in cellulose insulation to achieve R-60 (approximately 16.5 inches settled depth). Baffle vents to remain in place; new cellulose will not block soffit ventilation. Phase 2 — Crawlspace: Convert vented crawlspace to conditioned (sealed) crawlspace. Install 2-inch closed-cell spray foam to underside of subfloor (R-13) and 2-inch closed-cell spray foam to interior of crawlspace foundation walls (R-13). Seal all crawlspace vents. Install 10-mil reinforced poly vapor barrier on crawlspace floor, lapped and taped at seams, lapped 6 inches up foundation walls and secured.
Attic air sealing: Two-part spray polyurethane foam (low-expansion) for penetrations and gaps Recessed light covers: rigid foam box + Great Stuff PRO Gaps & Cracks at perimeter Pull-down stair: pre-cut rigid foam cover with weatherstrip gasket Attic insulation: Blow-in cellulose: Nu-Wool Premium or equivalent recycled cellulose, Class 1 fire-rated Target depth: 16.5 inches at settled depth = R-60 Installation: machine-blown in minimum 2 passes; depth gauges placed at 150 sq ft intervals Baffle vents (soffit): existing AccuVent baffles to remain; any damaged baffles to be replaced before insulation install Crawlspace encapsulation: Subfloor and foundation walls: closed-cell spray polyurethane foam, Bayseal CC-2.0 or equivalent, 2-inch application (R-13) Vapor barrier: Stego Wrap 10-mil or equivalent reinforced crawlspace barrier Vent seals: rigid foam plugs with foam tape gasket at all existing vents (8 vents confirmed during site walk)
Baseline conditions (pre-install): Attic: existing R-13 blown-in fiberglass with significant air bypasses at penetrations and pull-down stair Crawlspace: vented, uninsulated subfloor, single-layer poly vapor barrier (torn in 3 locations) Post-installation targets: Attic: R-60 blown-in cellulose + sealed air bypasses Crawlspace: R-13 closed-cell spray foam at subfloor and walls, fully encapsulated floor Blower door test: Northside Insulation will perform a blower door test (ACH50 measurement) before and after this project. Report provided at completion showing pre- and post-improvement air changes per hour. Utility rebate: [Utility name] offers a $350 rebate for attic insulation upgrades meeting R-49 or higher in qualifying homes. This project qualifies. Northside will submit rebate documentation on your behalf; rebate check issued to homeowner within 6-8 weeks of utility processing. Blower door test documentation is required for submission and is included in this project. Note: This project may qualify for the federal Energy Efficient Home Improvement Credit (25C) — up to 30% of insulation costs, maximum $1,200 per year. Consult your tax preparer. Northside will provide an itemized receipt with material specs for your records.
Phase 1 — Attic Air Sealing & Insulation: Attic air sealing: Foam penetrations, top plates, plumbing/electrical chases: $280 Recessed light can covers (14 cans, IC-rated confirmed — sealing only): $210 Pull-down stair rigid foam cover and gasket: $165 Air sealing subtotal: $655 Existing insulation removal and disposal: Blown-in fiberglass removal (approx. 900 sq ft attic floor): $480 Haul and disposal: $120 Removal subtotal: $600 New cellulose installation (900 sq ft to R-60): Material (blown-in cellulose, 46 bags estimated): $690 Labor: $1,080 Depth gauges, set-up and cleanup: included Cellulose subtotal: $1,770 Phase 1 total: $3,025 Phase 2 — Crawlspace Encapsulation: Closed-cell spray foam — subfloor (900 sq ft at 2 inches): $2,340 Closed-cell spray foam — foundation walls (320 sq ft at 2 inches): $832 10-mil reinforced vapor barrier (1,100 sq ft with laps): $880 Vent seals (8 vents): $240 Labor — demo, prep, foam, vapor barrier installation: included in above Phase 2 total: $4,292 Project total: $7,317 Less estimated utility rebate (to be applied at invoice): -$350 Net after rebate: $6,967 Payment: 40% ($2,927) due at contract signing. Balance due on day of completion. Rebate check issued separately by utility to homeowner.
Phase 1 (attic): 1 full day. Air sealing in the morning; existing insulation removal and new cellulose install in the afternoon. Blower door test at end of day. Phase 2 (crawlspace): 1 full day, scheduled within 5 business days of Phase 1 completion. Spray foam requires 24-hour cure before vapor barrier installation — if crawlspace is large or complex, may require second half-day. Blower door report: delivered within 3 business days of Phase 1 completion. Warranty: — Cellulose installation: 1-year warranty on settled depth. If depth falls below R-49 equivalent at any measurement point within 12 months, Northside will add material at no charge. — Spray foam (closed-cell): 10-year warranty on adhesion and R-value per manufacturer spec (Bayseal). — Vapor barrier: 1-year installation warranty on seams and terminations. Damage from standing water, pests, or mechanical impact not covered. — Air sealing: no settled depth or compression risk; no separate warranty needed. If blower door results do not improve from baseline, Northside will return to identify and seal additional bypasses at no charge. Exclusions: mold remediation, structural repairs, pest damage, HVAC modifications. If crawlspace shows active water intrusion at installation, spray foam will be paused and client notified before proceeding.

Create Your Free AccountQuote R-values, not just materials. A proposal that says "blown-in attic insulation" tells the client nothing. One that says "R-60 blown-in cellulose at 16.5 inches settled depth" tells them exactly what they're buying and makes your competitors' vague quotes look sloppy. DOE recommends R-49 to R-60 for attics in most of the country (Climate Zones 4-8). Put the target R-value in the proposal and state what depth that requires. Clients who have done any research will notice — and trust you more.
Spray foam, cellulose, and batts are not interchangeable. Open-cell spray foam runs R-3.7 per inch; closed-cell runs R-6.5 per inch and doubles as a vapor barrier — at 3 to 4 times the cost of blown-in. Blown-in cellulose is the workhorse of attic insulation: dense-pack performs well, settles predictably, and is made from recycled fiber. Fiberglass batts are cheap and fast but air sealing is poor — every gap around a joist or wire becomes a thermal bypass. The right answer depends on the location, budget, and whether vapor control matters. Spell out why you're recommending what you're recommending. Clients who understand the trade-off don't shop on price alone.
Air sealing is not optional — it's 30 to 40 percent of the job. Insulation slows conductive heat loss. It does almost nothing about infiltration. An attic with two uninsulated recessed lights and a pull-down stair can lose more heat through air movement than through the rest of the ceiling combined. If you're insulating an attic, seal the attic floor first: top plates, ceiling penetrations, recessed cans, plumbing chases. Put air sealing as a separate line item in the proposal so clients see it as real work, not an afterthought. Contractors who skip this step get callbacks and moisture problems.
Call out utility rebates if they exist in your market. Many utilities offer $150 to $500 back on qualifying insulation upgrades. Some require a pre-installation energy audit or blower door test. If your work qualifies, say so in the proposal and describe what the client needs to do to claim the rebate. If you perform the blower door test pre- and post-install, mention it — before-and-after ACH50 numbers are the only objective proof that the job did what you said it would. Contractors who help clients get rebates get more referrals than contractors who don't.
Address existing insulation before you quote the upgrade. Adding R-19 blown-in over existing R-11 batts does not get you to R-38 — compressed or settled batts lose R-value, and any moisture damage or contamination in the existing layer needs to come out first. State in the proposal whether you are adding over, removing and replacing, or removing damaged material on a time-and-materials basis if you find something unexpected. Clients who find out after the fact that their old insulation had to be removed first — and that it cost extra — rarely leave good reviews.
