Cost calculator

A number in ten seconds. No form first.

Pick what you’re insulating, put in the square footage, get a range. Nothing to fill in, nothing to sign up for.

We preselect what’s normally right for that area. Change it to compare.
square feet
Rough is fine. Length × width of the space is close enough.

This is a ballpark based on typical projects in our area — not a quote. Your real number depends on access, existing conditions, prep and code requirements, and we won’t know it until someone has stood in the space.

What moves your real number up or down

The things a calculator can’t see.

Access

A walk-in basement is a different job from a two-foot crawl space with a hatch behind the water heater. Everything takes longer when you can’t stand up.

What comes out first

Wet, compacted or rodent-contaminated insulation has to be bagged and hauled. We quote that as its own line so you can see it.

Obstructions

Ductwork, piping, wiring, piers, a finished ceiling. Every obstacle is something to mask, work around and detail properly.

Code requirements

Where an ignition or thermal barrier is required over exposed foam, that’s material and labour on top — and it’s in our quote rather than a surprise at inspection.

Existing conditions

Damp concrete, past water damage, mold, a bath fan venting into the attic. Sometimes these have to be fixed before we can start at all.

Doing more than one area

Two areas in one visit cost far less than two visits. If you’re weighing several jobs, price them together.

Why our calculator gives a bigger number than some others

Plenty of insulation calculators return a single tidy figure that turns out to be the material cost, or the cheapest possible version of the job, or a number designed to get you onto a call before the real price appears.

Ours shows a range because the range is real. The low end is a straightforward job with good access and nothing to remove. The high end is the same square footage in a difficult space with prep work. Most houses land somewhere between, and we’d rather you saw both ends now than felt ambushed at the estimate.

If a quote you receive comes in far below the low end here, ask what thickness they’re installing and whether removal, prep and any required barrier are included. That’s usually where the difference is hiding.

About this calculator

  • Good enough to decide whether to keep reading, not good enough to budget from. It uses the same per-square-foot pricing our completed jobs actually landed at, so the range is honest — but it can’t see your access, your existing insulation or the bath fan venting into your attic. Treat it as the number that tells you whether this is a $2,000 conversation or a $9,000 one.

  • Because the same square footage genuinely varies that much. A 1,200 sq ft attic with a walk-up staircase, nothing to remove and simple framing sits near the bottom. The same 1,200 sq ft with knee walls, a low pitch, old wet insulation and a dozen can lights to detail sits near the top. Narrowing the range would mean guessing, and a guess that’s too low helps nobody.

  • Drywall or any finish work over the foam, HVAC changes, electrical work, moisture remediation, drainage, structural repairs, and permits where your township requires them. If any of those turn out to be needed, they’re on the written estimate as separate lines — and in a few cases we’ll tell you one of them has to happen before we can do our part at all.

  • No. The number appears as you type and nothing is sent anywhere. We put the calculator in front of the form deliberately — the point is that you can find out roughly what this costs without talking to a salesperson, including finding out that it’s more than you want to spend right now.

  • Not usefully. It’s built on residential project data, and commercial pricing works differently — phasing, off-hours work, coatings, fire-rated assemblies and access equipment all move the number in ways this can’t model. Send drawings through the commercial page instead and you’ll get an itemised proposal.

  • No — the figures are what the work costs before any incentive. New Jersey and Pennsylvania both run energy programs and federal credits have applied to qualifying insulation and air-sealing work, but eligibility depends on the measure, the program and the certifications involved, and the rules change. We check what applies to your address during the assessment, and your tax advisor should confirm anything you plan to claim.
