REPCO, now under the leadership of Northern Building Products, is in its fourth decade in supplying replacement window products to the renovation or rehabilitation market.

REPCO will continue to supply a full line on commercially rated aluminum products, tested and certified by an independent testing laboratory for the commercial rehabilitation market (apartment buildings, schools, businesses). REPCO also exports its window products to overseas markets.

REPCO has supplied its aluminum products to both the public and private sectors in the Mid-Atlantic States: to housing authorities and housing preservation agencies in all of the major cities in Massachusetts, New York, New Jersey, Pennsylvania, Delaware, Maryland, Virginia and the District of Columbia; to office buildings and factories; to apartment complexes large and small.

REPCO's aluminum products, appropriately outfitted with available accessories, have been approved and accepted by historical commissions in New York City, Philadelphia, Baltimore, Washington DC and Cape May, NJ.
