Lawrenceville sits at the heart of Gwinnett County, where older homes near the courthouse square mix with sprawling subdivisions built over crawl spaces and vented attics that bake at 130-150 degrees from May through September. Atlanta Spray Foam Insulation has been sealing and insulating homes and commercial buildings across the Atlanta area since 2012, and we know Lawrenceville's specific challenges: humid summers that drive moisture into crawl spaces, aging attics with flattened or missing insulation, and the energy bills that follow.
When a Lawrenceville homeowner calls us, it is usually because a room does not cool, a crawl space is damp, or an attic has become a liability. We arrive with a clear assessment, honest pricing, and the experience to know whether your home needs spray foam, air sealing, or insulation removal and replacement. We are fully insured, and we leave your property clean.
Spray Foam Insulation in Lawrenceville (30046)
Lawrenceville's building stock spans from 1900s homes on brick piers to 1980s and newer two-story subdivisions with vaulted great rooms and finished space over the garage. The constant is the same: a vented attic where ductwork sits in 140-degree heat, a crawl space under red clay where humidity condenses on rim joists and band joists, and wall cavities that were never filled or have settled over the decades. Spray foam solves all three. Closed cell foam seals rim joists and crawl spaces against moisture and holds R-value in tight spaces. Open cell foam fills wall cavities and attics where access is good and cost matters. Air sealing around electrical boxes, rim joists, and ductwork penetrations stops the leaks that make cooling and heating expensive.
We have been serving Lawrenceville and the surrounding Atlanta area since 2012. Our team handles attic insulation in homes where access is tight, crawl space spray foam on homes stacked over damp clay, wall injection in older homes with empty cavities, and removal and replacement when insulation has failed or is contaminated. We arrive with written estimates that specify R-value and thickness, and we work with the building codes and permit requirements that apply at your address in Lawrenceville.

How a Job Works in Lawrenceville
Step one is a free on-site assessment. We walk your attic, crawl space, or the walls you want to seal. We measure the area, identify what has to come out first (damp insulation, old fiberglass, or debris), and spot the air leaks that matter. We listen to what you are trying to fix: a cooling bill that is out of control, a room that never reaches temperature, or moisture in a crawl space. We then provide a written estimate with the R-value and thickness we recommend, the cost, and what the work entails.
Step two is the spray. On attic jobs, we set up mechanical ventilation so the smell does not linger in your living space. We control the thickness and ratio on every pass, and we respect the re-entry window: typically twenty-four to forty-eight hours before the space is safe to occupy. If your home is occupied, we coordinate the work time and make sure you know when the area will be ready. On crawl space jobs, we may have to work around tight access or a low header, and we do that without rushing or cutting corners. If old insulation has to come out first, we remove it and haul it away.
Step three is cleanup and a final walkthrough. We leave your property clean, and we answer any questions about the work we did and how to care for the space going forward.
Spray foam pricing in Lawrenceville depends on the area to cover, the R-value you need, whether you choose open cell or closed cell, and what has to be removed first. A typical attic spray foam job runs from $1.50 per square foot for open cell to $1.20 per board foot for closed cell, depending on thickness and coverage. Crawl space jobs usually start at $2,500 and go up with the area and the access. Rim joist and band joist sealing starts at $650. Wall injection in older homes typically runs $2 per square foot. Insulation removal starts at $950, and full replacement jobs start at $2,800. The best way to know what your home will cost is a free on-site estimate.
