A siding calendar for Hagerstown
Hagerstown was laid out by Jonathan Hager in 1762, and many of its houses have stood through a long run of winters. Old or new, siding lasts longest when someone looks at it every season and fixes small problems before water gets into the wall. This calendar sets out what to check and when.
NOAA's engineering weather set has no station near Hagerstown, so this calendar doesn't quote weather figures.
Spring: March to May
- Walk around the house on a dry day and photograph each wall.
- Look for winter damage: cracked or loose panels, split boards, gaps at corners and trim, nails backing out.
- Check the bottom of each wall, where snow and splash sit. Peeling paint, soft wood or swollen boards there mean water is getting in.
- Look at the flashing over windows and doors and where roofs meet walls.
- Clean gutters and downspouts so spring rain runs away from the walls.
- On an older house, look closely at painted wood trim and sills, which usually fail before the siding itself.
Summer: June to August
Hagerstown's city water comes from the R.C. Willson plant on the Potomac River and the W.M. Breichner plant on the Edgemont Reservoir; the city's 2025 water report says Edgemont and Breichner were off-line for dam and plant repairs then, so the Willson plant was supplying all of it.
- Aim sprinklers away from the house. Wherever the water comes from, a daily soaking keeps siding wet.
- Wash the siding with a garden hose and a soft brush. A pressure washer can force water behind the laps and strip old paint.
- Make repairs and re-caulk joints around windows, doors and penetrations.
- Paint wood siding and trim within the temperature and humidity range on the paint label.
- Cut back shrubs and vines that touch the walls.
Fall: September to November
- Finish painting and caulking before nights get too cold for them to cure.
- Seal gaps where pipes, cables and vents go through the wall.
- Clean gutters after the leaves fall.
- Shut off and drain outdoor faucets and put hoses away.
- Move firewood and stored items away from the walls.
Winter: December to February
- Keep snow from piling against the siding for long stretches.
- Watch for ice at the eaves, which can push meltwater under the roof edge and down inside the wall.
- Check interior walls near windows and corners for damp spots or stains.
- Note what needs fixing and plan it for spring.
Hiring for bigger repairs
The Maryland Home Improvement Commission lists siding, roofs, waterproofing, doors and windows among the services it covers, and offers a public license-status check for contractors and salespeople. Before you sign for any siding work, ask for the MHIC number and look it up.
Keep a record
Keep photos from each season, the siding and paint products and colors, repair invoices and warranties together. On an older house, add notes on what you found under the old siding. That record makes the next repair and any sale simpler.
