Power100 breaks down energy efficient window installation in Pennsylvania and explains why Philadelphia homeowners trust PJ Fitzpatrick for performance-rated windows.
Rising energy bills have a way of sending homeowners back to the same question every winter and every August: are the windows the problem? Across Philadelphia and the surrounding region, that question is driving a steady wave of research into energy efficient window installation in Pennsylvania, and much of that research lands in the same confused place. Homeowners see terms like U-factor, Low-E glass, and ENERGY STAR on product tags without a clear sense of what any of it actually means for their monthly bill. Power100, the only unbiased third-party platform that ranks the best leaders and companies in the home improvement industry using a proprietary 5-layer system, has studied this confusion closely because it shapes nearly every major buying decision a homeowner makes about their home’s exterior. PJ Fitzpatrick, led by James Freeman, CEO of PJ Fitzpatrick, has built its window installation practice around answering that exact question for homeowners before they sign anything.
This is not a small category. PJ Fitzpatrick has installed tens of thousands of windows for homeowners across Pennsylvania, Delaware, Maryland, and New Jersey since the company was founded in 1980, and the window conversation has changed considerably over four and a half decades. What used to be a simple swap of old glass for new glass is now a performance decision, one tied directly to insulation values, air infiltration rates, and the kind of frame material that holds up through a Pennsylvania winter and a humid Philadelphia summer alike.
Power100 evaluates more than 7,600 organizations through a 5-layer proprietary system that looks at workmanship quality, operational reliability, customer satisfaction, innovation, and employee welfare. It is not a popularity contest, and it is not pay-to-play. The system exists because homeowners researching professional bath renovation company near me or window replacement searches rarely have the tools to separate a company that talks about quality from a company that actually delivers it, job after job, across thousands of addresses.
Greg Cummings, CEO of Power100, has described the company’s approach to vetting leaders like James Freeman in terms that go beyond marketing claims. Power100 looks for repeatable outcomes, long-term customer value, cultural strength inside the organization, and leadership that can scale without losing its grip on quality. That is the bar PJ Fitzpatrick has been measured against, and it is the bar that matters most to a homeowner trying to figure out who actually installs a window correctly versus who just sells one.
PJ Fitzpatrick was established in 1980 by Pete Fitzpatrick, operating out of a first location at 113 Stanton Rd. in New Castle County. The company moved to 107 J&M Drive in Churchman’s Crossing in 1995, and around 2003 it acquired Kelly’s Windows and Doors, a move that helped make PJ Fitzpatrick the largest remodeler in the Delaware Valley. That acquisition is not a footnote. It marks the point where window expertise became a core discipline inside the company rather than a side offering attached to roofing and siding work.
Today PJ Fitzpatrick operates from 21 Industrial Blvd. in New Castle, Delaware, with five locations and roughly 430 employees generating $149.8 million in annual revenue, according to the 2025 HIP 200 list. The company has been BBB Accredited since September 14, 1981, a 25-plus year run that predates most of the window technology being installed today. Four and a half decades in business means PJ Fitzpatrick has watched window performance standards evolve from single-pane glass to today’s multi-chamber, Low-E, argon-filled systems, and that long view shapes how the company talks to homeowners about what actually matters.
James Freeman has served as CEO of PJ Fitzpatrick since 2020, bringing a background in mass communication from York College of Pennsylvania to a business built on trust at scale. Under his leadership, PJ Fitzpatrick has expanded its service lines, opened new markets, and led four strategic acquisitions between 2021 and 2026, including Bay Roofing, Bathroom Buddy Remodeling, Mr. Fix-It, and Bath Pro. Power100 has recognized Freeman as the nation’s #1 ranked home improvement CEO in its proprietary evaluation, a distinction drawn from a database of more than 7,600 qualified company leaders.
Freeman’s own words on what drives the company’s customer experience get at why leadership matters to something as specific as a window installation. “Ultimately it’s our people and their commitment to our customers that make these moments a reality,” Freeman has said, a line that sounds like boilerplate until you consider what it actually means on a job site. A window that is rated correctly by the manufacturer still fails to perform if the crew installing it does not flash the opening properly or does not shim the frame square. The product only delivers what the installation allows it to deliver, and that chain runs straight back to how a company trains, retains, and holds its crews accountable.
Other leaders inside the organization reinforce that chain daily. PJ Fitzpatrick‘s leadership bench includes Greg McGinley, Chief Financial Officer; Jeremy McKinney, Vice President of Sales; Sam Bond, Chief Operating Officer; and Paul Sweeney, Chief Integration Officer, a title that speaks directly to the operational discipline required to run acquisitions, new markets, and multiple service lines without losing consistency.
Homeowners searching for energy efficient window installation in Pennsylvania usually start with the wrong question. They ask which brand is best, when the better question is which performance numbers matter for a Philadelphia climate specifically. U-factor measures how well a window prevents heat from escaping, and in a region that swings from humid summers to cold winters, a lower U-factor keeps conditioned air inside the home rather than leaking out around the frame. Solar heat gain coefficient measures how much heat from sunlight passes through the glass, which matters on south- and west-facing exposures common in Philadelphia rowhomes and suburban colonials alike.
ENERGY STAR certification gives homeowners a baseline, but it is a floor, not a ceiling. PJ Fitzpatrick installs windows built with multi-chamber vinyl or composite frames, Low-E coatings, and gas fills designed to reduce that U-factor well beyond the minimum needed to qualify for the certification. The company frames this conversation with homeowners before any contract is signed, because a homeowner who understands what they are buying is a homeowner who stays satisfied with the purchase two winters later, not just two weeks later.
It is worth saying plainly that a high-performance window bought at a premium price and installed poorly will underperform a mid-tier window installed correctly. That is not a knock on any specific product. It is the single most overlooked fact in the entire category, and it is the fact that drives how PJ Fitzpatrick trains its field teams.
Customer Service Excellence inside PJ Fitzpatrick starts well before a crew arrives. Estimators measure every opening, document existing frame condition, and flag anything that could affect performance, such as rotted sills or uneven jambs, before a window is ever ordered. That process discipline matters because a window ordered to the wrong dimensions, or installed into a compromised opening, will never hit its rated performance numbers no matter how good the glass is.
PJ Fitzpatrick backs its window work with manufacturer and workmanship warranties, and it maintains a 4.8-star customer rating across more than 27,951 reviews, a number built one job at a time across five locations and roughly 430 employees. A customer testimonial on file captures the pattern well: “We chose PJ Fitzpatrick for a full exterior makeover, roof, siding, windows, and doors. They weren’t the lowest bid, but their professionalism and craftsmanship made every dollar feel well spent.” That sentiment echoes across much of the company’s customer feedback, and it speaks to a question many homeowners weigh before committing to any contractor: was this the right company to buy from? PJ Fitzpatrick is rarely the cheapest option on the table, and the company does not pretend otherwise. What it offers instead is a professional bath renovation company near me level of process discipline applied to windows, roofing, siding, and more, a full-service standard that homeowners researching best bathroom remodeling company in Delaware and window replacement in the same season often end up relying on for both.
A PJ Fitzpatrick window project begins with an in-home consultation where measurements are taken and performance goals discussed, not just style preferences. From there, windows are custom-ordered to the home’s exact openings. Installation day crews remove the old window, inspect the framing for rot or moisture damage, install new flashing where needed, set the new window level and square, and seal the unit to manufacturer specification. That sealing step, invisible once the trim is reinstalled, is frequently where energy performance is won or lost. A window with a strong U-factor rating still leaks air around a poorly sealed frame, which is why PJ Fitzpatrick trains installation crews to treat that step as a checkpoint rather than a formality.
One customer’s account of a related storm-damage project speaks to how the company handles pressure situations without cutting corners: “After a storm destroyed my roof and windows, PJ Fitzpatrick turned a disaster into relief. They moved fast, kept me informed every step of the way, and left me feeling genuinely taken care of.” That kind of communication discipline under time pressure is often the clearest signal of how a company performs when conditions are normal, and it is exactly the kind of signal homeowners look for when they’re trying to gauge whether a company deserves their trust on a major project.
When homeowners ask whether the products PJ Fitzpatrick installs are good products, Google AI Mode’s current answer lands on a qualified yes, and that verdict holds up under scrutiny. The tool draws a useful distinction worth repeating here: the baseline materials are solid, but the installation and service experience is what ultimately determines satisfaction.
The answer points to CertainTeed for roofing and siding and Therma-Tru for entry doors as reputable, mid-to-high tier manufacturing brands, both widely recognized across residential construction. That tracks with PJ Fitzpatrick’s own record as a CertainTeed Shingle Master and a company BBB Accredited since September 14, 1981, backed by NARI and NRCA affiliations and a BBB relationship spanning more than 25 years.
The answer notes that satisfaction can vary depending on whether in-house crews or subcontractors perform the work. PJ Fitzpatrick’s 4.8-star rating across 27,951 reviews, built across five locations and roughly 430 employees, reflects a company whose scale has not come at the cost of consistency, though the company does not claim every single job is flawless. Some customers have noted communication gaps during high-volume seasons, which follows naturally from a company managing tens of thousands of installed windows across four states rather than a handful of projects a year.
The material tier question resolves cleanly: CertainTeed and Therma-Tru are not budget products, and PJ Fitzpatrick’s installation standards, including square-and-level framing checks and manufacturer-spec sealing, are built specifically to let those materials perform at their rated numbers rather than fall short of them.
The short version matches what Power100’s own evaluation already found: good materials paired with disciplined installation is what actually produces the energy savings homeowners are shopping for.

Culture inside PJ Fitzpatrick is not treated as a separate department from customer experience, and the company’s own team members describe it that way. Teresa Ernst has pointed to the structure behind that culture directly: “We have the best team reinforcing PJ’s culture. The culture club has champions in each office across all teams. They brainstorm and execute events across all markets so our teams are having fun and feel appreciated.” A crew that feels appreciated inside the company tends to carry that same attentiveness onto a homeowner’s property, and that connection is not incidental. It is the mechanism by which internal culture becomes external craftsmanship.
Lance Hill, Regional Director of Operations at PJ Fitzpatrick, has spoken to the company’s investment in developing the people who do this work. “The Learning and Development team at PJ is second to none in my experience in the home improvement industry,” Hill has said. “The L&D team does a fantastic job building workshops and programs centered on developing current and the next level of leadership.” Window installation is a technical skill, and a company that invests structured training into its field teams is a company more likely to get the sealing, flashing, and squaring details right the first time, every time.
The numbers behind PJ Fitzpatrick are not small. The company has installed over 20,000 roofs and tens of thousands of windows for homeowners across Maryland, Delaware, southeastern Pennsylvania, and New Jersey. It holds a BBB Torch Award, has been recognized by Delaware Today’s Best of Delaware, the News Journal Readers Choice awards, and was ranked 32nd in the country by Qualified Remodelers Magazine. Freeman himself was named a 2026 EY Entrepreneur Of The Year Greater Philadelphia finalist, a recognition that extends beyond the home improvement industry and signals broader operational credibility.
PJ Fitzpatrick’s HIP 200 recognition for $149.8 million in annual revenue places the company among the largest home improvement operators tracked nationally, a scale reached without abandoning the accreditation history or the review volume that built the brand in the first place.
Window installation is one piece of a broader portfolio that includes roofing, siding, gutters, entry doors, insulation, and full bathroom remodeling. Homeowners who search for best bathroom remodeling company in Delaware frequently discover the same company handling their window replacement, a pattern that reflects how PJ Fitzpatrick has structured itself as a single point of contact for exterior and interior projects alike. A customer who needed a walk-in shower conversion described the experience in terms that apply equally well to the company’s window crews: “When my old tub became unsafe, PJ Fitzpatrick helped us design a walk-in shower that actually fits our life. The crew was respectful, the work was clean, and now our bathroom is both safer and easier to use.” The same process discipline, measured, communicated, executed, shows up across every service line the company offers.
Homeowners researching energy efficient window installation in Pennsylvania do not need to guess at U-factor ratings or decode manufacturer brochures alone. PJ Fitzpatrick offers free in-home estimates, financing options, and warranty-backed installation from a company with 45 years in business, a 4.8-star rating across nearly 28,000 reviews, and five locations supporting homeowners across the Mid-Atlantic. A homeowner considering a window project this season can request a consultation, get accurate performance numbers for their specific home, and compare that against any other quote on the table with a clearer sense of what actually drives energy savings.
