P.A. Martin & Sons in Baltimore: Full-Frame Window Replacement with In-House Manufacturing
P.A. Martin & Sons is a Baltimore-based window manufacturer and installer that builds vinyl and fiberglass replacement windows on-site and installs them throughout the region, operating since 1989. Unlike national chains or contractors who source windows elsewhere, the company controls the entire process from fabrication to installation, which means shorter lead times and direct accountability for fit and finish in older Baltimore rowhouses and mid-century homes where off-the-shelf dimensions often fail.
What P.A. Martin & Sons actually does
The company manufactures custom replacement windows in its Baltimore facility and handles full installation. This matters in a city where 60 percent of housing stock was built before 1950: standard window sizes don't fit rowhouse openings reliably, and poor installation—gaps around frames, misaligned sashes—defeats any window's efficiency. P.A. Martin builds to your opening and installs with attention to weather-sealing and trim work that frame-less mail-order operations skip. The shop handles residential projects only; commercial work is outside their scope.
Services and pricing
P.A. Martin & Sons manufactures vinyl and fiberglass replacement windows. Vinyl runs roughly $300 to $500 per window (material and installation combined) depending on size and style; fiberglass, which holds paint longer and resists rot better in humid climates, starts around $450 and runs higher. Custom shapes (arches, triangles) add 30 to 50 percent. Storms and screens are separate line items. Confirm current pricing directly, as material costs fluctuate. The company does not sell pre-made stock windows; every window is built for your specific opening, which adds one to three weeks to the timeline depending on volume. Installation typically happens within two weeks of manufacturing. Estimates are free and involve an in-home visit to measure and assess frame condition.
How it compares to other Baltimore window options
National chains like Renewal by Andersen and Pella operate in Baltimore but rely on regional warehouses and standardized sizes, which means higher prices (often $600 to $900 per window installed) and less flexibility for odd dimensions. Sears Home Services still handles window installation in parts of Maryland, though availability and response time vary. Local independent installers often source windows from national suppliers and mark them up; you pay for the product twice over. P.A. Martin's advantage is control: custom manufacturing in Baltimore shortens supply chain and puts accountability on one company. The tradeoff is that you cannot walk into a showroom and see 50 samples; you work from a small selection of vinyl and fiberglass options and trust their expertise on what works in your home. Choose P.A. Martin if your windows are an unusual size, if you value single-source accountability, or if you have deep-energy retrofit goals and want a contractor who understands rowhouse thermal profiles. Choose a national chain if you want maximum style variety upfront or prefer a recognizable brand name on the warranty.
Who it suits and who it does not
P.A. Martin works best for rowhouse owners, owners of pre-1960 homes with non-standard openings, and anyone unwilling to accept partial solutions. The company's in-house manufacturing means they can replace broken sashes, repair frames, and adapt to settlement or tilted openings. Projects involving six or fewer windows are routine. Large whole-house jobs (15+ windows) work fine but may require scheduling patience. If you need windows installed in two weeks and live in a standard suburban tract house with common dimensions, a big-box contractor or national chain will move faster. If you rent, want temporary solutions, or are unsure about staying in your home, the custom-manufacturing lead time and per-window cost may feel excessive.
What the first visit involves
An estimator visits your home to measure each opening, assess frame condition, and note problems: rotted wood, settled openings, interior trim styles, sash weights if you have double-hung windows. They ask about your priorities: energy efficiency, ease of operation, noise reduction, or paint-ability. You discuss vinyl versus fiberglass and any style constraints (colonial, modern, casement versus double-hung). They provide a written estimate listing each window by size, material, and cost, plus installation fees. No deposit is required to get an estimate. If you accept, you schedule a start date; P.A. Martin manufactures your windows, then schedules a crew for installation, which usually takes one day for 5 to 8 windows.
Hours, parking, and logistics
P.A. Martin & Sons operates Monday through Friday, 8 a.m. to 4:30 p.m., with occasional Saturday appointments available by request. The showroom and manufacturing facility are located in Baltimore proper; confirm the exact address when you call, as facility locations can change. Parking is available on-site. Installations happen during business hours on weekdays and some Saturdays. The company is licensed and insured in Maryland. Lead times shift with order volume; verify turnaround before committing, especially if you have a hard deadline.
P.A. Martin & Sons fills a genuine gap in Baltimore's window market by refusing to treat rowhouse owners as customers of a national template. For anyone who has fought with an ill-fitting replacement window or suffered through a year of delays, local manufacturing and installation accountability matter.
