Hidden gaps in your home let cold air in and warm air out all winter. We find them with a blower door test and seal them for good - with before-and-after results you can see.
Air sealing in Mansfield closes the gaps, cracks, and hidden openings that let outside air push into your home and conditioned air escape - most jobs are completed in one day using foam and caulk, and results are verified with a blower door test before and after. Insulation slows heat from moving through walls and ceilings, but if air is flowing freely through gaps, that insulation cannot do its job.
Many Mansfield homes were built in the mid-twentieth century when gaps around pipes, wires, and attic hatches were simply accepted as part of construction. Those gaps have been leaking heat - and letting in cold, dust, and moisture - ever since. If you have already added insulation and your bills still have not improved as much as you expected, unsealed air leaks are the most likely reason. Combining air sealing with basement insulation addresses two of the biggest sources of heat loss in older Mansfield homes at the same time.
The biggest leaks in most homes are not around windows and doors - those are usually already weatherstripped. The real culprits are attic hatches, the gaps where pipes pass through floors, recessed lights, and the rim joist where the house meets the foundation. A trained contractor knows where to look first, and a blower door test confirms the results with a real number rather than a guess.
If your gas or electric bill climbs sharply during the coldest weeks, your home is working overtime to replace heat that is escaping through gaps. A well-sealed home holds its temperature more steadily, so the furnace does not run as hard. If your bills feel out of proportion to the size of your home, air leaks are a likely culprit in Mansfield's cold winters.
Stand near a baseboard, an exterior wall, or an electrical outlet on a cold day. If you feel a noticeable flow of cold air, that is outside air coming through gaps in the building. In older Mansfield homes, these drafts are especially common near the attic hatch, around the fireplace, and along the rim joist in the basement.
If dust reappears on surfaces within a day or two of cleaning, it is often being carried in by air moving through gaps in the building envelope. This is especially noticeable in older Mansfield neighborhoods where construction gaps are common. Sealing those entry points reduces the amount of outdoor dust, pollen, and debris pulled inside.
If you have already had insulation installed and your bills have not improved as expected, unsealed air leaks underneath or around the insulation are almost certainly the reason. Sealing first and then insulating is the correct order - doing it in reverse leaves most of the benefit on the table.
We start every job with a blower door test - a diagnostic fan mounted in your front door that depressurizes the house so we can locate exactly where air is moving in and out. That reading tells us where to focus. We then work through the attic floor, rim joist, basement penetrations, and any other identified problem spots using spray foam and caulk. A second blower door test after the work confirms the improvement in a number you can see. When combined with attic air sealing, the result is a substantially tighter home with measurably better energy performance.
For homes where both air sealing and insulation are needed, we recommend doing them together. The two upgrades work in tandem: air sealing stops the air movement, insulation slows the heat transfer. When one is missing, the other underperforms. Many Mansfield homeowners who have added insulation in the past but still feel drafts are in exactly this situation. We can assess whether air sealing alone will close the gap, or whether pairing it with additional insulation - such as in the attic or basement - will deliver the full improvement. The ENERGY STAR seal and insulate program outlines the combined approach that most contractors in this region follow.

Mansfield sits in north-central Ohio and regularly sees winter temperatures drop into the single digits. That kind of sustained cold exposes every gap in a home - you feel drafts that are invisible in fall, furnaces run constantly to keep up, and heating bills spike from November through March. Air sealing pays off faster here than in milder regions because the temperature difference between inside and outside is so extreme for so many months. A large share of Mansfield homes were built before 1980 when gaps around pipes and wires were simply accepted - which means more opportunity for meaningful improvement once the work is done. Homeowners in Medina and Ontario face the same winter conditions and the same mid-century housing stock - this is a regional pattern, not unique to Mansfield.
Mansfield summers also add a moisture dimension that matters for air sealing. Warm, humid outdoor air pushing into a cooler home through gaps can condense inside walls and attic spaces - which over time causes mold and wood rot, especially in homes built before modern moisture barriers were standard. A contractor familiar with Ohio's two-season dynamic will seal with this in mind, not just focus on keeping cold out in winter. Ohio utility rebate programs through AEP Ohio and FirstEnergy have annual funding limits - the AEP Ohio energy efficiency page shows what is currently available, and scheduling earlier in the year improves your odds of capturing available rebates before they run out.
We ask a few basic questions - age of your home, any specific drafts or high bills you have noticed, and whether prior insulation work has been done. We reply within one business day and can typically schedule an assessment within one to two weeks.
We mount a temporary fan in your front door and depressurize the house to find exactly where air is moving in and out. This gives you a baseline number and tells us where to focus the sealing work - so nothing is guessed.
After the assessment, we explain what we found and give you a written estimate covering scope and cost. We also identify any AEP Ohio or FirstEnergy rebates that apply to your project and walk you through the paperwork requirements.
The crew works through the attic, basement, and rim joist systematically. Most homes are done in one full day. At the end, we run a second blower door test so you can see the measurable improvement in a real number before we leave.

(567) 345-1126We test before we start and again when we finish. You get a real number showing how much tighter your home is after the work - not just a verbal assurance that gaps were sealed. This is the standard that the{' '}Building Performance Institute sets for certified energy auditors, and it is how we operate on every job.
We know Mansfield homes - the older brick and wood-frame construction near downtown, the mid-century ranch houses in the newer neighborhoods, and the specific ways Ohio's cold winters and humid summers create problems that milder-climate contractors miss. We seal for both seasons, not just winter drafts.
Both utilities serve the Mansfield area and offer rebates for qualifying air sealing work. These programs have annual funding limits. We help you identify what you qualify for and provide the documentation needed to apply - so you capture the rebate before it runs out for the year.
Most homes in Mansfield need both air sealing and insulation to get the full benefit. We offer combined project pricing so you get both upgrades done efficiently without paying the mobilization cost twice.
Air sealing is the kind of improvement that changes how your home feels every day - fewer cold spots, more stable room temperatures, and a heating bill that does not keep climbing. We make it verifiable so you know the investment was worth it.
