Maintenance Ideas


Ideas for Inspecting Aging Homes

Roof and Exterior

  • rotting attic vent screens -- possible squirrel and animal entry

  • rusting roof vent pipes and rotting rubber gaskets —- possible leaking roofs

  • worn out roof shingles —- leaks

  • gutters and downspouts full of silt or leaves or bent, and hence leaking

  • trees and bushes growing up around the chimney -- an issue if you burn wood

  • chimney caps rusting out, or missing

  • chimneys that are used a lot and may have creosote buildups

  • wood rot in the door and window trim

  • crumbling decks

  • twisted or rotten boards

  • garage door door hardware that’s rusting

  • reports of falling ceiling panels in the drywalled garage ceilings -- humidity and or nail rust

  • rotting mailbox posts

  • faded and or cracked and or settled driveway asphalt

  • fence materials degrade over time, and fences sag. At some point it is time to replace it.


  • windows that are twin layered and fogging up —- the seals have given out and water vapor gets in — worth replacing

  • skylights with leaks and or cracks in the outer layers -- water accumulates between the layers and could eventually leak into the ceiling



  • have they overgrown on your property?

  • are they shedding on your roof and filling your gutters


  • air filters in the furnace — dirty and recirculating dust, and impeding air flow

  • rusty furnace chassis -- eventual gas leakage through cracks -- potential hazard

  • (Do you have smoke and carbon monoxide detectors -- they are cheap and last for years)


Water Heaters:

  • leaky water heater

  • copper water pipes with pin hole leaks — water damage from leaks

  • warn out water faucets

  • washers, valves, and corrosion in the fixtures



  • electrical outlets and switches that have stopped working

  • bent/worn contacts or perhaps screws holding wires have loosened

  • corroded outdoor light fixtures 



  • air leaks in the walls from cracks in the wall materials, and the concrete basement

  • burnt out incandescent or fluorescent lights

  • rotting woodwork like porch rails and columns

  • grungy carpets -- from many years of use

  • stair railings where the mounts are breaking

  • linoleum floors that have seen better days



  • dryer vents clogged with dryer lint

  • dryers full of dryer lint after many years


Gas Stoves

  • burnt out gas jets



  • handles, keys, locks, latches all are wearing out

  • external door paint -- is it fading?



  • how is the road in front of your place? Let the Montgomery County DOT know directly or through 311


Shed Guidelines for Hollybrooke

  1. Sheds must conform to all zoning regulations.

  2. Shed construction requires both permits and inspections. Regulations may be found on the county web site:

  3. A plot plan and shed description must accompany all applications.

  4. Only one shed is allowed per lot.

  5. A shed may not be used as a living space for humans or animals.

  6. A shed must be located in the backyard of a home.

  7. Only wood or vinyl sheds are permitted. No metal sheds are permitted. Sheds must be anchored to resist wind loads, as required by the county building code.

  8. Sheds may be 100 square feet or less, with an eight (8) foot height at the roof peak.

  9. The shed roof must be sloped. Flat roofs on sheds are not permitted.

  10. Shed floors must be solid concrete, concrete pavers, or pressure treated lumber. A suitable barrier of lattice, chicken wire, concrete blocks, etc., must be included in the design and construction to prevent burrowing animals from making a habitat under the shed.

  11. If electrical service is desired for the shed, it must be underground and according to code. If an exterior light is installed, efforts should be made to shield neighbors from light overrun.

  12. Ladders, hoses, tools, etc., may not be attached to the exterior of the shed walls or roof.

  13. An effort should be made to match the shed roof and walls to the main structure of the house.

  14. Placement of a shed on a property line is not permitted. A shed may be placed against the house but not connected. Location must be away from ground level utility housings.

  15. In the townhouse areas, sheds may not be located in the common space. Sheds should be located near the deck even if that requires installation near the ground level utility housings.

  16. Suitable landscaping should be provided to integrate the shed into the property.
