State College Insulation provides blown-in insulation, attic upgrades, spray foam, and air sealing for homeowners in Lewisburg and across Union County. We work on the pre-1940 Victorian and Federal-style homes near Market Street and Bucknell University, the rental properties throughout the borough, and newer residential construction on the outskirts of town. We reply within one business day.
Lewisburg attics in older Victorian and Federal-style homes often have low clearance, tight access hatches, and irregular joist spacing from original 19th-century construction - conditions that make batt installation difficult without damaging plaster ceilings below. Our blown-in insulation service fills these attics completely without opening finished surfaces, increases total depth over any existing material, and conforms to irregular framing that standard batts leave with gaps.
A large share of Lewisburg homes were built before 1940, and many have original insulation that has compressed and lost most of its effectiveness - or no insulation at all above the top-floor ceiling. Union County winters bring 30 to 35 inches of snow and temperatures that regularly drop into the single digits, and an under-insulated attic loses heat continuously from November through March. Upgrading the attic floor is the single highest-impact insulation improvement for most Lewisburg homeowners.
Lewisburg homes near the west branch of the Susquehanna River benefit from spray foam at the rim joists and foundation perimeter because it seals air and resists moisture at the same time. The brick and stone foundations common in pre-1940 Lewisburg homes have irregular surfaces that fiberglass batts cannot fill completely, and spray foam conforms to every gap regardless of shape - providing a complete thermal and air barrier at the base of the home.
Lewisburg homes built in the 1800s and early 1900s have accumulated gaps around pipes, wires, and framing penetrations that have been widening through decades of freeze-thaw cycles. Adding insulation over unsealed gaps does not stop the heat loss - warm air simply escapes through those openings first. We seal all penetrations at the attic floor and rim joist before any insulation goes in, which is what makes the upgrade perform as expected rather than as a partial improvement.
Newer homes on the outskirts of Lewisburg and in Kelly Township built in the 1980s and 1990s often have crawl spaces with minimal insulation in the floor assembly above. Cold floors on the first story, drafts near the baseboard, and higher heating bills than similar homes nearby are the common signs. Insulating and air-sealing the crawl space ceiling and rim joists addresses all three directly.
Many Lewisburg homes near the Susquehanna River have stone or masonry basements that are uninsulated at the rim joist and foundation walls. These perimeter areas are where cold air enters in winter and where moisture from the river-adjacent soil can be a concern in spring. Rim joist spray foam and basement wall insulation seal both problems at once, improving comfort on the first floor and protecting the foundation from repeated moisture contact.
Lewisburg is a Union County borough where a large share of homes were built before 1940, and many date to the mid-1800s. These are Victorian and Federal-style homes with original wood framing, brick exteriors, plaster walls, tall narrow windows, and stone foundations - built long before insulation requirements existed. The Market Street corridor and the streets surrounding Bucknell University are where these older homes are most concentrated, and they are architecturally distinctive but also among the most energy-inefficient buildings in the area. The freeze-thaw cycles of Union County winters - where temperatures swing above and below freezing dozens of times each year - gradually widen gaps in the older masonry and wood framing, increasing air infiltration year over year in homes that were already under-insulated.
The west branch of the Susquehanna River runs along Lewisburg, and spring snowmelt combined with heavy rain can raise water levels quickly. Low-lying properties in and near the borough have a history of flooding, and basements and crawl spaces in those areas can see moisture intrusion that needs to be addressed before insulation is installed. Bucknell University shapes the local housing market, and a portion of the borough's homes near campus have been rented to students for years, sometimes without meaningful maintenance during that time. If you have recently purchased one of those properties, the attic, rim joists, and crawl space often need more attention than the exterior of the house suggests. A free on-site assessment identifies what is actually there before any money is committed to repairs.
Lewisburg is a Union County borough, and when insulation projects in the borough require permits - typically when attic or basement work is part of a larger conversion to livable space - we work with the local permitting office directly. Most standalone insulation upgrades in Lewisburg do not require a permit. The borough has a compact historic core with older homes on small lots, many of them with tight access to attic hatches and original plaster ceilings below the attic floor. We know how to work in these spaces without damaging the finishes that make older Lewisburg homes worth owning. The Borough of Lewisburg maintains resources for local permit requirements.
Market Street and the surrounding blocks near Bucknell University are where the pre-1940 homes are most concentrated. Route 15 runs through the area and connects Lewisburg to the broader central Pennsylvania corridor. Moving outward from the borough core, Kelly Township has newer ranch and two-story colonial homes built from the 1980s through the 2000s that are reaching the age where original insulation is no longer performing well.
We also serve homeowners in neighboring communities. If you are in Selinsgrove to the south in Snyder County, or in Sunbury further south along the Susquehanna Valley, we serve those areas as well and are familiar with the older housing stock common throughout this stretch of central Pennsylvania.
Reach out by phone or through the contact form and describe what you are experiencing - high heating bills, cold rooms, visible ice dams on the roofline, or a drafty first floor. We respond within one business day and schedule a time to visit your Lewisburg home.
A technician visits your Lewisburg home, checks the attic, rim joists, crawl space or basement, and any areas you have identified as problems. For homes near the Susquehanna, we check moisture conditions in the foundation before recommending insulation. The assessment is free and comes with no obligation - you receive a written scope and price before deciding anything. Cost and timeline are addressed at this step.
Most Lewisburg insulation projects finish in a single day. We air-seal penetrations before adding any blown-in material, work around original plaster ceilings and wood trim without damaging them, and clean up the attic access area before leaving. You do not need to vacate the home during the job.
After the work is complete, we walk you through what was installed, where, and at what depth. You receive written documentation of the work. If questions come up in the weeks after the job, we are reachable by phone - we do not disappear after the invoice is paid.
No obligation. We assess your Lewisburg property, explain what we found, and give you a written price before any work begins.
(814) 996-0035Lewisburg is a borough in Union County, Pennsylvania, with a population of around 5,700 people. Founded in the early 19th century and sitting on the west branch of the Susquehanna River, Lewisburg has a well-preserved historic downtown that sets it apart from most small Pennsylvania towns. The Market Street corridor and the surrounding blocks are lined with Federal and Victorian-style homes and commercial buildings from the 1800s, many of them still in use as single-family homes or converted rentals. The borough has been recognized for its historic character, and the original building fabric along its main streets is largely intact. You can read more about the borough on the Lewisburg Wikipedia page. Bucknell University, founded in 1846 and one of Pennsylvania's most recognized liberal arts and engineering schools, sits within the borough and is the town's defining institution - shaping both the housing market and the character of the neighborhood closest to campus.
Moving outward from the historic core, newer residential development in and around Kelly Township includes ranch and two-story colonial homes built from the 1980s through the 2000s - a very different property type from the Victorian in-town homes, with different insulation needs and access conditions. The homeowners we work with in Lewisburg range from longtime owners of historic in-town properties to newer buyers who have recently purchased rental homes near campus. Both groups benefit from knowing that neighboring communities including Selinsgrove in Snyder County are also within our service area, served by the same crew familiar with central Pennsylvania housing and climate.
