Mayfair is one of Philadelphia’s classic Northeast neighborhoods — a planned community built over former farmland from the 1920s through the 1950s, after the Market-Frankford El put Center City about twenty minutes away. Centered on Frankford and Cottman Avenues, it filled in with wide gridded blocks of brick and stone-front rowhomes and twins, designed for the automobile age with front lawns, stoops, and rear-alley garages. Most of that mid-century housing still stands, and each home carries its own structural story. ValueGuard’s ASHI-certified home inspectors in Mayfair have been reading this neighborhood since 1997, and we’ve built our home inspections in Mayfair around exactly these older-home differences.

i. Why this neighborhood is different
A planned Northeast grid. Rowhomes by the thousand.
Mayfair went up fast between the 1920s and 1950s — block after gridded block of brick and stone-front rowhomes and twins built for working families across the Lower Northeast. A thorough home inspection in Mayfair means understanding mid-century rowhome construction. Here’s what we focus on:
1920s–1950s Planned Rowhomes
Mayfair filled in during the auto age as the city pushed northeast — wide gridded blocks of brick and stone-front rowhomes and twins with front stoops and rear-alley garages. These homes reward careful evaluation of brick and stone-front masonry, the entry and steps, the roofs, and the systems that age first in a mid-century build.
Brick & Stone-Front Rowhomes
Most of Mayfair is brick or Wissahickon-stone-front rowhomes and twins, many with slate mansard fronts, bay or arched windows, and covered entries. We look closely at party walls, the brick and stone-front masonry and pointing, and the transitions where attached homes meet.
Slate Mansards & Flat Rear Roofs
Mayfair rows often pair a slate or shingled mansard front with a flat or low-slope rear roof, each with its own failure points. We check the covering, flashing, valleys, and signs of water entry closely on every inspection.
Century-Old Sewer Laterals
Mayfair’s homes are typically served by clay or cast-iron sewer laterals from the early 1900s. A sewer scope catches root intrusion, offsets, and collapses — repairs that run $8,000 to $20,000.
Older Wiring & Electrical Panels
Mayfair homes span the 1920s to the 1950s, so wiring ranges from knob-and-tube and cloth-insulated circuits in the oldest blocks to early modern panels elsewhere — often with fuse boxes, undersized service, or aging galvanized plumbing. We document what’s present and what it means for safety, insurance, and your budget.
Basements, Moisture & Foundations
Many Mayfair homes have block or poured foundations and finished or semi-finished basements. We look for moisture intrusion, efflorescence, grading and drainage problems, and signs of foundation movement — plus how well any basement finishing was done.

A note on Mayfair’s older homes
Mayfair’s appeal is its space and value — solid brick and stone-front rowhomes and twins, most built between the 1920s and 1950s, with front yards and rear garages. That character comes with systems worth understanding before you buy: clay or cast-iron sewer laterals, older wiring and panels, galvanized plumbing, and slate or flat roofs near the end of their service life. None of it is a dealbreaker — but knowing the condition of each, with photos and realistic cost framing, is exactly what an experienced Mayfair home inspector delivers.
From our recent caseload
Recently inspected in Mayfair.
Three homes from recent ValueGuard inspections in Mayfair — a brick rowhome with an arched front window, a stone-front end-of-row, and a brick row with a slate mansard front. One neighborhood, three entirely different inspections. Swipe or use the arrows to see all three.
No. 01
Brick Rowhome with Arched Window
A Mayfair brick rowhome (No. 1607) with a slate mansard front, an arched stone-trim window, and a brick party-wall chimney. Homes like this reward attention to the brick masonry and pointing, the slate mansard and flashing, the entry and steps, and the older systems behind a mid-century front.
No. 02
Stone-Front End-of-Row
A Wissahickon-stone-front Mayfair home at the end of its row, with gabled dormers, a slate roof, and an exposed brick side wall. End and corner homes have their own priorities — the exposed side wall and its weatherproofing, the stone-front masonry and pointing, and the roof and flashing.
No. 03
Brick Row with Slate Mansard
A two-story Mayfair brick rowhome (No. 6346) with a slate mansard front, replacement windows, and a stone-trimmed entry. Attached rows like these reward attention to party walls, the slate mansard and its flashing, the windows and lintels, and the older systems behind the façade.

ii. The four services that matter most
What to inspect in Mayfair.
Home Inspection
A complete evaluation of structure, roof, electrical, plumbing, HVAC, and major systems — delivered as a photo-rich report the next business day. Tuned to whichever Mayfair era your home represents.
Sewer Scope Inspection
Essential on Mayfair’s older homes, where clay and cast-iron laterals from the early 1900s are prone to root intrusion and collapse. Our camera travels the lateral from cleanout to main. A few hundred dollars now can save tens of thousands later.
Radon Testing
Radon turns up in Philadelphia homes of every age, Mayfair included. Our PA DEP-certified technicians use tamper-resistant electronic monitors with 48-hour turnaround. Mitigation, if needed, typically runs $800 to $2,500.
Termite, WDI & Mold
Older Mayfair homes warrant a wood-destroying-insect inspection (required by most lenders) and, where there’s a damp basement or past moisture, mold testing. Both can be added to your home inspection in a single visit.
