Why Decks Sink & Rot on Paw Paw Lake

The "Muck" Problem: Soft Soil Foundation Failure

Paw Paw Lake and Little Paw Paw Lake waterfront properties face a critical foundation challenge that standard deck construction cannot overcome: soft, organic soil with high water table that causes standard concrete footings to settle and sink over time.

The soil composition near Coloma's inland lakes:

The standard concrete footing failure sequence on lakefront properties:

  1. Contractor digs holes to 42-inch frost line depth (code requirement)
  2. Pours concrete footings in soft muck—footing sits on compressible organic soil
  3. Deck is built and loaded with furniture, planters, hot tubs, people
  4. Weight compresses muck beneath footings—footings begin sinking
  5. Settlement is differential—posts closer to water (worst soil) sink more than posts away from water
  6. Deck develops slope toward lake—boards no longer level, water pools, structure racks
  7. Ledger board attached to house cannot sink—creates stress on connection, eventually pulling away
  8. After 5-10 years, deck has settled 2-6 inches and requires complete rebuilding

We've measured settlement on lakefront decks ranging from 2 inches (minor annoyance) to 8 inches (catastrophic structural failure requiring demolition). Every dollar saved using standard footings gets spent on premature replacement plus the inconvenience of losing deck access for weeks during rebuilding.

WTS II Contracting uses helical pier foundation systems on all Paw Paw Lake soft-soil properties:

Helical Pier Technology:

Installation Process:

  1. Hydraulic driver attachment mounts to skid-steer or mini-excavator
  2. Pier screwed into ground at post locations
  3. Torque monitored during installation—minimum torque requirement ensures adequate bearing capacity
  4. Piers driven until refusal (won't penetrate further) or engineered depth reached
  5. Bracket attached to pier top—post mounts directly to bracket
  6. Total installation time: 30-45 minutes per pier versus 2-3 hours per concrete footing (dig, form, pour, cure)

Cost Comparison:

For Coloma lakefront properties where deck replacement costs $25,000-40,000, helical piers are the only foundation system that makes economic sense.

The "View Killer" Railing: Preserving Your Million-Dollar Sightline

Paw Paw Lake waterfront properties command premium prices—$500,000 to $2,000,000+—primarily due to unobstructed water views. Yet standard deck railing systems featuring vertical wood pickets or composite balusters block 40-60% of the sightline when seated, negating the very amenity that justified the property purchase.

The standard railing visibility problem:

Standing at the rail provides clear views, but the primary deck use—sitting at dining table, relaxing in lounge chair, entertaining guests—occurs while seated. Standard picket railings force you to stand up to see the lake you paid premium prices to access.

WTS II Contracting specializes in view-preserving railing systems that provide code-required safety while maintaining unobstructed sightlines:

Cable Railing Systems (Most Popular):

Glass Panel Systems (Ultra-Premium):

Horizontal Wood or Composite (Budget Alternative):

For a typical 12x16 lakefront deck with 40 linear feet of railing, upgrading from wood pickets ($1,600-2,400) to cable system ($3,000-4,800) adds $1,400-2,400 to project cost. But it transforms the deck from "view-obstructed outdoor room" to "transparent extension of interior living space with uninterrupted water access"—directly increasing property value and daily enjoyment.

Moisture & Rot: The Humidity Challenge

Paw Paw Lake creates a microclimate of elevated humidity—water vapor rising from the lake surface keeps lakefront properties 10-15% more humid than inland areas just 1-2 miles away. This constant moisture accelerates wood deterioration and creates maintenance nightmares for deck materials not engineered for wet environments.

The humidity degradation sequence on pressure-treated lumber:

Annual staining/sealing becomes semi-annual on lakefront decks—double the maintenance burden. And despite diligent maintenance, pressure-treated lumber still degrades faster due to relentless moisture exposure.

WTS II Contracting recommends PVC-capped composite decking for all Paw Paw Lake properties:

Trex Transcend Lineage Collection:

TimberTech AZEK (Ultra-Premium Alternative):

Cost justification for lakefront properties:

For waterfront homeowners who prioritize lake time over deck maintenance, composite decking is the only logical choice.

Common Deck Mistakes in Coloma

The Jurisdiction Trap: Waterfront Setbacks and Lot Coverage

Coloma has dual jurisdiction (City of Coloma and Coloma Charter Township) with significantly different zoning requirements for waterfront lots—particularly lot coverage ratios and setback distances from water. Building without understanding these requirements results in stop-work orders, variance applications, or worst-case, mandatory demolition.

Lot Coverage Ratio:

Waterfront Setback Requirements:

Side Yard Setbacks:

WTS II Contracting handles all zoning compliance before design:

This upfront due diligence adds 1-2 weeks to project timeline but prevents the $5,000-15,000 cost of demolishing non-compliant construction.

Ledger Board Flashing: The Cottage Retrofit Challenge

Many Paw Paw Lake cottages date to the 1950s-1970s—era of minimal building codes and DIY construction. These properties often have irregular siding (vertical board and batten, T1-11, metal), minimal house wrap, and uneven wall surfaces. Attaching deck ledger boards to these structures without proper flashing creates the rot conditions responsible for 90% of deck collapses.

The cottage ledger failure sequence:

  1. DIY builder or unlicensed contractor bolts ledger directly against irregular siding
  2. No flashing installed—or inadequate aluminum flashing that doesn't integrate with house wrap
  3. Gaps between ledger and uneven siding create water collection points
  4. Rain runs down behind siding, drains into ledger cavity
  5. Water sits against rim joist (often original 1950s lumber) indefinitely
  6. Rim joist rots from inside out—rot hidden behind siding and ledger
  7. Ledger attachment bolts lose holding power as wood deteriorates
  8. Eventually ledger pulls away during heavy load (party, snow accumulation)—deck collapses

WTS II Contracting installs comprehensive double-flash ledger systems on all cottage retrofits:

Step 1: Siding Removal and Inspection

Step 2: Self-Adhesive Membrane Application

Step 3: Metal Flashing Installation

Step 4: Ledger Attachment

Step 5: Siding Replacement

This double-flash system adds $300-600 in materials and 4-6 hours labor compared to "bolt and go" approach. But it prevents the rim joist rot that requires $8,000-12,000 in house structural repairs plus complete deck rebuilding.

Cantilever Overreach: The "Trampoline Bounce" Problem

Lakefront homeowners naturally want the deck to extend as close to the water as possible—maximizing the feeling of being "over" the lake. DIY builders and inexperienced contractors accommodate this desire by cantilevering deck joists far beyond the beam, creating structural flex and bounce that makes the deck feel unsafe.

The cantilever failure mode:

The issue is exacerbated with composite decking—heavier than wood (65-70 lbs per square versus 40-45 lbs), creating more dead load that amplifies deflection.

WTS II Contracting frames with conservative beam-to-joist ratios for rock-solid feel:

Cantilever Limits:

Joist Sizing:

Beam Placement:

This conservative framing approach adds approximately $400-800 in lumber costs (10-15%) but transforms user experience from "bouncy and concerning" to "solid and confident."

Frequently Asked Questions: Deck Building in Coloma, MI

Do I need a permit to replace deck boards in Coloma?

Usually no—simple board replacement on existing framing (same-for-same material swap) typically doesn't require a permit in either City of Coloma or Coloma Charter Township. However, permits are required for: (1) Any structural changes to framing, posts, beams, or footings, (2) Enlarging the deck footprint or height, (3) Replacing railings (safety-critical component requiring inspection), (4) Repairing or replacing ledger board attachment to house. If your project involves any structural modifications beyond simple decking replacement, a full building permit with inspections is required. Additionally, if you're adding features like built-in benches, pergolas, or stairs, these trigger permit requirements. WTS II Contracting recommends confirming with your specific jurisdiction's building department before starting work—unpermitted structural work discovered during home sale can delay or kill transactions, and retroactive permitting requires expensive engineering analysis and potential structural upgrades to meet current code.

What is the best decking material for full sun?

A light-colored composite with heat-reflective technology, so it doesn't burn bare feet coming off the boat. Paw Paw Lake decks receive intense sun exposure—especially south and west orientations with no tree shade. Standard composite (first-generation technology) absorbs heat and can reach surface temperatures of 160-180°F in July/August sun—hot enough to cause first-degree burns on bare feet. WTS II Contracting recommends Trex Transcend Lineage with Cool-Touch technology—advanced infrared-reflective pigments that reduce surface temperature by 30% compared to standard composite. Light colors (grays, tans, Island Mist) stay coolest—typically 110-120°F maximum even in full sun. For comparison: dark brown standard composite reaches 170°F, making decks unusable during peak summer months. Additional considerations for sun exposure: (1) Fade warranties—Transcend offers 25-year protection against significant color fade from UV, (2) Scratch resistance—PVC cap layer prevents barefoot traffic and dragged furniture from damaging surface, (3) Zero maintenance—sun-damaged pressure-treated requires annual re-staining, composite requires nothing. For ultimate heat resistance: TimberTech AZEK in lightest colors stays coolest but costs 20-30% more than Trex Transcend.

Can you build a deck on the second story?

Yes, we specialize in multi-level decks with integrated water-management systems to keep the patio below dry. Second-story decks on Coloma lake homes present unique engineering challenges: (1) Structural loading—upper deck must carry live load plus snow load without transferring excessive force to lower level, (2) Water management—rain and melting snow draining through upper deck boards creates constant drip on lower patio, (3) Wind exposure—elevated decks face higher wind loads requiring hurricane ties and engineered connections. WTS II Contracting installs under-deck drainage systems (Trex RainEscape, TimberTech DrySpace) that capture water falling through upper deck and channel it to gutters—keeps lower patio completely dry for year-round use. System consists of vinyl membrane installed on lower deck joists before upper deck boards go on, sloped to perimeter gutters, sealed at all penetrations. Additional second-story requirements: 42-inch minimum railing height (versus 36" for ground level), stronger joist-to-beam connections to resist uplift, proper flashing where upper deck attaches to house second floor. Multi-level decks typically cost $50-75 per sq ft installed (versus $40-60 for ground level) due to additional engineering, drainage system, and access complexity.
