  3. • preservation • rehabilitation • restoration • reconstruction •Basic Standards for all • Historic Character preserved • Documentation • Use most gentle action or treatment • New material to match old • Repair rather than replace • Treatment to be reversible

  4. The Secretary of the Interior’s Standards for Rehabilitation • Two important goals: • The preservation of historic materials • The preservation of a building’s distinguishing character • Character refers to all those visual aspects and physical features that comprise the appearance • Overall shape, materials, craftsmanship, decorative details, interior spaces, and features

  5. Building Maintenance Introduction

  6. Building Maintenance Introduction “Water always wins, that is why there is a Grand Canyon” -Glenn Haege, America’s Master Handyman

  7. Reference Materials • Secretary of the Interior’s Standards for the Treatment of Historic Properties: • NPS Preservation Briefs (1-47 briefs) • MHPN Historic Resource Council Directory • This Old House Magazine • Old House Journal • Local HDC Standards/ Design Guidelines • APT- Association for Preservation Technology

  8. Workshop Handouts • Home Maintenance Inspection Checklist • PowerPoint Presentation Handout • Preservation Brief #47: Maintaining the Exteriors of Small and Medium Size Historic Buildings • Lead Resource Guide for Owners of Older and Historic Buildings • Simple Steps to Working Windows

  9. General Maintenance Introduction • Why perform general maintenance? • Who should perform maintenance? • Assessment = detailed non-destructive visual inspection of an existing structure. • Always follow rules of safety for climbing ladders/ working with tools/ performing maintenance.

  10. Before you get Started • Research repair history from previous owner/ Building Department/ Neighbors. • Prepare yourself with proper tools, clothes, binoculars and camera. • Practice looking at your house in detail throughout the year to detect problem areas/ materials. Watch water! • Design issues vs. improper construction vs. material deterioration or lifespan. • Create running checklist to prioritize repairs

  11. Inspection/Maintenance Areas • Exterior “Envelope” • Roof • Walls • Windows • Doors • Projections 2. Site 3. Interior Areas 4. Non-occupied Spaces 5. Mechanical\Electrical\Plumbing Systems (MEP)

  12. 1. Envelope Roof: Shingles • Inspect all areas of roof at least once a year: covering materials, drip edges, flashings, valleys/ ridges. Roof: Chimneys/Vents • Step flashing, sloped concrete cap with expansion at flue, screened flue cap. • Roof penetrations: verify seals at vents, pipes, antennas, and connections to structure. • Ice and water shield or heat tape at overhangs.

  13. 1. Envelope Roof: Chimney Chimney step flashing, sloped concrete cap with expansion at flue, screened flue cap. Roof: Flashing and Vents Verify seals at vents, pipes, antennas, and connections to structure.

  14. 1. Envelope Roof: Gutters and Downspouts • Flush gutters and leaders, after cleaning large debris, with a garden hose to clear away remaining grit and to observe how water drains through system. • Verify gutters are attached securely to fascia. • Check for leaks at joints- use butyl caulk to seal. • Verify proper slope- min. ¼” rise per 1’-0” of run. • Check condition of wood fascia behind gutter also.

  15. 1. Envelope Walls: Exterior Cladding • Sealant at open joints, apply trim if missing, monitor decorative trim connections and safety condition. • Inspect all wood pieces for insect damage.

  16. 1. Envelope Walls: Wood • Keep it dry, and keep it clean. • Maintain slope of wood to shed water. • Research proper wood fillers for your application- epoxy (or Bondo in some cases) Walls: Stucco • Important to maintain flashings and repair damage quickly to keep moisture out. Walls: Masonry • Proper tuckpointing

  17. 1. Envelope Windows • Monitor operation, perimeter seals and weatherstrip, tight seal when closed (adjust casing brass screws). Apply sealant at siding/ casing connection. • Use storms for inefficient non-insulated units. • Re-glaze with glazing putty-prime bare wood first. • Scrape, prime, and repaint wood items.

  18. 1. Envelope Doors • Monitor operation, perimeter seals and weatherstrip, bottom sweeps, tight seal when closed. Apply sealant at siding/ casing connection. “Spring Bronze” weatherstrip

  19. 1. Envelope Projections: Porches, Balconies, etc. • Securely attach loose fixtures or features • Look for evidence of water damage • Use acrylic latex caulk at open wood joints- monitor damage. • Scrape, prime, and paint wood and metal elements. Repair before replace.

  20. 1. Envelope Foundations • Fill in cracks in masonry with epoxy based patching compound. • Repoint masonry joints- use lime mortar! • Remove efflorescence with non-metallic brush. • Use acrylic latex caulk at open wood joints- monitor damage. • Scrape, prime, and paint wood and metal elements. Repair before replace. • Maintain vents and holes thru exterior materials

  21. 1. Envelope

  22. 2. Site

  23. 2. Site Drainage systems • Water must flow away from building from roof to street. Verify grades, existing swales, water from neighbors yards, catch basins and street drains. • Standing water, water stains, flaking paint. Paved areas • Fill in cracks, provide expansion joint at building edge, slope away from building.

  24. 2. Site Landscaping • Clean leaves from gutters and yard drains. Trim branches away from building and power lines. Keep groundcover and bushes away from foundation. • Vines are attractive, but dangerous! • Keep mulch and grade at least 8” down from exterior house covering. • Garages and Outbuildings

  25. 3. Interior Areas General observations • Standing water or excess moisture, wet stains or mildew, flaking paint or plaster, rust on metal components. Rising Damp. • Paint and plaster repair- watch lead based materials. • Safety issues: handrails, stair nosings, worn flooring materials. • Leaky or faulty mechanical, plumbing or electrical systems.

  26. 3. Interior Areas Doors and Windows • Ensure all are in working order • Watch out for condensation, air infiltration, etc.

  27. 4. Non-Occupied Areas Basement: Walls • Monitor to determine level of moisture. Patch cracks in wall, seal all penetrations. Basement: Floor • Clean floor drains. • Maintain sumps and humidifiers. Basement: Overhead Basement: Windows/Vents • Check pipes for leaks, condensation, insulation.

  28. 4. Non-Occupied Areas

  29. 4. Non-Occupied Areas Basement: Insulation • Verify insulation in joist space and vapor barriers. Basement: Plumbing Leaks • Clean floor drains. • Maintain sumps and humidifiers\dehumidifiers Basement: Pests • Keep clean! Dirt = moisture collection.

  30. 4. Non-Occupied Areas Crawl Space • Monitor to determine level of moisture. Crawl Space: Walls Crawl Space: Floors • Provide vapor barrier on sand floor. Crawl Space: Overhead Crawl Space: Ventilation • Verify proper ventilation! Clean existing vents, provide insect screens, add vents if needed.
