Hudson County and the older parts of Essex and Bergen are full of row houses, 2 to 6 family buildings and mixed-use properties with a shop or office on the ground floor. One roof, one heating system and a handful of tenants mean the top floor usually complains first, and the owner pays for the heat that leaves through the attic or roof deck.
We insulate and air seal these buildings the same way we do a single-family house, scaled to the property: find where air and heat are escaping, seal it, then insulate to the target for the space. We work around tenants, agree on access in advance and keep each day contained so the building keeps running.
What's included
- Site visit covering the attic or roof deck, top-floor ceilings, basement or crawl space ceilings and shared chases.
- Air sealing of the paths that move air between floors and into the attic: chases, top plates, penetrations and hatches.
- Blown-in insulation for open attics and spray foam for roof decks, rim joists and spaces where loose material does not fit.
- Insulation of basement and crawl space ceilings under unheated areas, where the floor above is cold.
- Checks for moisture, roof leaks and ventilation before anything is covered.
- A written scope for the whole building, with the work broken out by area so you can approve it in stages.
- Access planning with the owner or manager, and cleanup at the end of each working day.
How pricing works for a building
Pricing
Quoted per building after a site visit
We do not publish a price range for commercial and multifamily work, because the buildings differ too much. Roof area, number of units, access, existing material and the condition of the roof deck all change the scope.
After the site visit you receive a written scope for the whole building, broken out by area. You decide what to approve and in what order.
What moves the price
- Size of the attic or roof deck and the number of separate roof sections.
- Access: occupied units, shared hallways, height and equipment space.
- Existing insulation and whether any of it has to come out first.
- Moisture or roof problems that need to be fixed before insulating.
How the work goes
- 1
Site visit. We walk the building with the owner or manager, look at the attic or roof deck and the lowest level, and note anything that needs attention first. It is free.
- 2
Written scope. You get a scope for the whole building, broken out by area, with the access plan.
- 3
Prep and access. We agree on dates with you and the tenants and protect shared areas.
- 4
The work. Air sealing first, then insulation, one area at a time. Spray foam on a roof deck sometimes needs a permit, so we confirm with the local construction office.
- 5
Walkthrough. We walk the finished work with you and clean up. Timing depends on the building, and the scope gives the schedule.
When to choose this vs a single-family service
If you own a one- or two-family house you live in, the single-family service pages describe the same work and the scope that applies. This page is for owners and managers who need a scope across several units or a mixed-use building.
Many buildings combine services, for example attic work on the top floor and a sealed, insulated basement ceiling. We scope them together so the work is done in the right order.
