Dry Rot & Wood Repair in Novi, MI

A deck surface can look like a small maintenance job while a support change affects plans, easements or environmental review. Novi’s published deck checklist makes those questions explicit.

Sources and their limits

Source scope matters: a historic district does not describe every home, and regional exposure is not a property diagnosis. These references are links only.

1. Wood Handbook, chapter 14: Biodeterioration of Wood

   USDA Forest Service, Forest Products Laboratory · Preserved local evidence packet · accessed 2026-09-19

   Scope: Original PDF and successful retrieval/hash in qa/seo-depth/common/pdf/common-usda-biodeterioration.*; inspected PDF pp. 1, 3–4, 7–8. General mechanisms, not municipal prevalence.

   Evidence: Decay fungi need moisture, oxygen and suitable temperatures. Wood that appears dry now may have decayed earlier. Surface stain is not equivalent to structural decay. Correct the moisture source when repairing decay; exposed assemblies require appropriate material selection. Freezing alone is not fungal rot.

2. Preservation Brief 39: Holding the Line—Controlling Unwanted Moisture

   National Park Service · Preserved local evidence packet · accessed 2026-09-19

   Scope: Parent-downloaded original retained in qa/seo-depth/common/pdf/common-nps-moisture.*; inspected PDF pp. 1–5, 7, 10–11. National technical guidance.

   Evidence: Diagnose before treatment. Roof runoff, ground drainage, condensation and irrigation can wet building materials. Misplaced sprinklers can wet foundations and walls. Ice can damage gutter seams and masonry through freeze-thaw; melting ice can carry water into assemblies. Keep records of visible changes; avoid indiscriminate waterproof coatings.

3. Preservation Brief 45: Preserving Historic Wood Porches

   National Park Service · Preserved local evidence packet · accessed 2026-09-19

   Scope: Shared national technical source retained in qa/seo-depth/common/pdf/common-nps-porches.*; inspected printed pp. 4–7. National technical guidance only; no territory geography or routing reused.

   Evidence: Porches combine decking, piers, columns, ledgers and decorative elements. Hidden deterioration can require professional investigation; a decaying ledger can be a major safety issue. Water enters open joints and column bases. Maintain and repair sound historic fabric before replacing irreparable portions; appearance alone cannot establish structural adequacy.

4. Reduce the Risk of Lead Exposure at Home

   US Environmental Protection Agency · Direct source checked · accessed 2026-09-19

   Scope: Original page captured as raw/technical-epa-lead.*; Lead-Based Paint section inspected. National safety guidance, not a diagnosis of any dwelling.

   Evidence: Pre-1978 homes are more likely to contain lead-based paint. Peeling paint and repair that disturbs coatings can generate hazardous chips and dust. Building age warrants precautions, not a claim that lead is confirmed at a property.

5. Official Census jurisdiction geometry with authorized proposed-territory classification

   US Census Bureau; local owner-confirmed coverage classification · Preserved local evidence packet · accessed 2026-09-19

   Scope: Read qa/seo-depth/proposed-boundaries/jurisdictions.json and validation.json, effective-city-candidates.json, AUTHORIZED-BOUNDARY-DEFAULTS.json. Census vintage January 1, 2026; classification authorized September 19, 2026.

   Evidence: Exact Census geometry identifies the named jurisdictions; full inclusion is an owner-confirmed operational coverage policy, not measured crew coverage or service fit. Related-place ranking uses straight-line separation of bounding-box midpoints of these geometries, not boundary adjacency or driving time. West Bloomfield uses layer 1 charter-township geography; Northville and Plymouth use layer 4 CITY features.

6. Southeast Michigan monthly climate normals

   NOAA National Weather Service Detroit/Pontiac · Direct source checked · accessed 2026-09-19

   Scope: raw/fh-noaa-normals.*; 1991–2020 normals, updated May 2021. Detroit station as regional reference only; office name does not add Pontiac to coverage.

   Evidence: Detroit monthly normals show winter freezing conditions, winter snow, and precipitation throughout the year. This supports seasonal snowmelt/freeze-thaw planning, not a freeze-thaw count or precipitation amount for any of the eight jurisdictions.

7. Novi Master Plan Steering Committee housing discussion, June 1, 2022

   City of Novi · Indexed excerpt only — limited evidence · accessed 2026-09-19

   Scope: Indexed 2022 working-document housing discussion using 2019 data, not the final 2025 plan or current stock. Original extraction attempted separately.

   Evidence: The discussion identifies substantial 1990s and 2000s building cohorts and a mix of detached and multi-unit housing. It does not inventory framing, cladding or deck condition.

8. Novi Residential Deck Requirements

   City of Novi Community Development Department · Direct source checked · accessed 2026-09-19

   Scope: raw/fh-novi-decks.*; five-page municipal submittal guidance. Permit scope and current code applicability require City review; no dimensions copied into DIY instructions.

   Evidence: Deck submissions call for a plot plan, framing/elevation/section drawings, woodland and wetland affidavits, and association approval where applicable. Decks cannot project into easements. The document makes site constraints and connections part of assessment, not just visible deck boards.
