Gutter Installation in Maryland

Local know-how

Gutters and gutter guards in Maryland

Outside the Baltimore and Washington metros, Maryland ranges from the mountains of Western Maryland to the Eastern Shore. Snow and ice in the west and coastal storms in the east both test gutters.

Frederick and Hagerstown have many older homes due for seamless replacement, while Eastern Shore homes benefit from corrosion-resistant materials and oversized downspouts.

In Frederick County and around Hagerstown, many newer subdivisions have builder-grade gutters that homeowners upgrade to seamless 6-inch systems with guards.

Rain, snow and the Chesapeake

Baltimore averages about 45 inches of precipitation and about 21 inches of snow a year at BWI Airport under the National Weather Service’s 1991–2020 normals. Rain is spread through the year, with summer thunderstorms, tropical remnants and nor’easters bringing the heaviest totals. Western Maryland gets far more snow; the Eastern Shore and the bay shoreline get more salt air and storm surge.

Rowhouses and older homes

Baltimore’s rowhouses, Annapolis’ colonial homes and older houses across the state often have flat rear roofs with scuppers, built-in gutters behind cornices, half-round gutters and shared gutters with neighbors. These call for experienced crews and coordination with neighbors. See gutters on row houses and gutters on historic homes.

Lead-safe work

Maryland has its own lead rules for older housing, especially rentals, and the federal EPA Renovation, Repair and Painting Rule requires certified firms and lead-safe practices when paid work disturbs more than 20 square feet of exterior paint on pre-1978 homes. Most of Baltimore’s rowhouses fall into that category.

Trees and suburbs

In Baltimore, Howard, Anne Arundel, Harford, Carroll and Montgomery Counties, suburbs are full of colonials, split-levels and townhouses from the 1950s onward under oaks, maples and tulip poplars. Those trees can fill a 5-inch gutter in days, and a clogged gutter in November often means ice in the channel in January. Guards and larger gutters help. See are gutter guards worth it?

Stormwater programs

Montgomery County’s RainScapes program and similar efforts in other jurisdictions have offered rebates for rain barrels, rain gardens and other practices that manage roof runoff. Program terms change; check current offerings. See rainwater harvesting and gutters and landscaping.

Basements and old drain lines

Many Maryland homes have basements, and older houses often have downspouts connected to underground clay or cast-iron lines that run to the street or the sewer. When those lines crack or clog, water backs up at the foundation in every storm. Test old lines with a hose before connecting new gutters, and replace or bypass failed ones with extensions or new pipe. Rowhouse leaders that tie into the sewer under the sidewalk deserve the same check. See underground downspout drainage and wet basement? check your gutters first.

MHIC licensing

The Maryland Home Improvement Commission (MHIC) licenses home improvement contractors, and it lists gutters and downspouts among the work that usually requires an MHIC license. Ask for the MHIC license number and look it up with the Maryland Department of Labor before you sign. Hiring a licensed contractor also gives you access to the state’s Guaranty Fund if something goes wrong; check current terms with MHIC.

Choosing gutters in Maryland

Size gutters and downspouts for summer downpours, keep scuppers and rear gutters on rowhouses clear, and carry water away from basements. Near the bay, choose corrosion-resistant materials and fasteners. Under oaks and tulip poplars, guards save time and prevent winter ice. Late summer and early fall are good times to schedule replacement. See how to choose a gutter contractor.

Chesapeake shoreline homes

Along the bay and its rivers, from Annapolis and Kent Island to the Eastern Shore, salt-tinged air and storm surge are part of life. Heavier-gauge aluminum or copper, stainless or compatible coated fasteners and sealed corners last longer, and downspouts should discharge where flood vents and crawl spaces stay clear.
