Back Deck
The exterior back deck is a versatile outdoor space designed for leisure, entertainment, and quality time with family or guests.
Typically constructed using durable materials such as pressure-treated wood, composite decking, or natural hardwood, back decks are designed to withstand constant exposure to outdoor elements while providing safe and functional access to your backyard.
A properly constructed and maintained deck enhances the overall value of the property and expands usable living space into the outdoors.
Warrantability
Alberta New Home Warranty Standards:
- 1-Year Warranty: Back decks may be covered under Alberta’s one-year materials and workmanship warranty for defects resulting from poor installation or material failures.
Builder’s Warranty:
- 1-Year Warranty: Builders typically provide a one-year warranty that includes defects in installation, such as loose boards, improper fastening, uneven construction, or poor drainage.
- Design flaws that compromise the structure within this period may also be covered.
- Damage due to weather conditions, natural aging, or lack of maintenance is not included.
Manufacturer’s Warranty:
- Composite decking manufacturers often offer warranties lasting 10–25 years, covering material defects such as cracking, splitting, or premature fading.
- Maintenance is a key factor in warranty eligibility, so poor care or use of incorrect sealing products could void the warranty.
Maintenance
- To ensure your back deck remains safe, functional, and visually appealing, follow these maintenance guidelines:
Cleaning:
- Sweep debris regularly to avoid buildup that could lead to mold or moisture damage.
- Clean the deck with a mild, non-abrasive cleaner or specialized deck cleaner every few months. Remove stains promptly to prevent discoloration.
Inspection:
- Conduct annual inspections to check for cracks, rot, loose boards, or structural movement. Pay close attention to joints, fasteners, and handrails.
Protective Measures:
- Apply a water-resistant sealant or stain to wood decks every 12–24 months to protect against UV damage, moisture, and rot. For composite decks, regularly check for surface integrity and clean as instructed by the manufacturer.
What to Avoid:
- Leaving furniture or planters in the same position for extended periods, especially on wooden decks, as it can lead to water pooling or mildew.
- Using harsh power washers, can damage wooden fibers or strip protective coatings.
- Ignoring drainage issues, which can weaken the deck foundation over time.
Common Issues, Warrantability, and Repair Solutions
1. Cracked or Warped Deck Boards

Warrantability:
- 1-Year Builder Warranty: Cracks or warping in deck boards may be covered if damage is due to material defects or poor craftsmanship (e.g., improper curing in composite material or faulty wood treatment).
- Manufacturer’s Warranty (Varies): Cracked or warped deck boards may be covered by the manufacturer’s material defect warranty.
- Weather exposure and poor maintenance are generally not covered.
Repair Solution:
- If within warranty period: Contact serviceQ to assess and engage the qualified trade.
- If outside warranty period: Engage a certified deck professional for repairs or board replacement.
2. Loose Boards or Protruding Nails

Warrantability:
- 1-Year Builder’s Warranty: Issues with loose boards or nails due to improper installation may be covered
- Beyond this period, repairs due to wear-and-tear or improper usage are typically not covered
Repair Solution:
- If within warranty period: Contact serviceQ to assess and engage the qualified trade.
- If outside warranty period: Engage a certified deck professional for repairs.
3. Rotting Wood or Fungal Growth

Warrantability:
- 1-Year Builder’s Warranty: may apply if rot stems from improper treatment or exposure caused by installation defects.
- Manufacturer’s Warranty (Varies): Material defects causing premature rot may fall under the manufacturer’s warranty.
- Rotting wood is typically not covered under warranties, as it results from lack of maintenance (e.g., failing to apply sealant or stain).
Repair Solution:
- If within warranty period: Report defects to serviceQ for an inspection.
- If outside warranty period: Consult a certified deck professional for removal and repair.
4. Water Damage or Pooling

Warrantability:
- 1-Year Builder’s Warranty: Water damage caused by poor construction or improper slope design may be covered
- Manufacturer’s Warranty (Varies): Composite deck products that absorb water due to manufacturing defects might qualify for manufacturer warranty coverage,
- Damage caused by neglect or lack of sealing is not covered.
Repair Solution:
- If within warranty period: Contact serviceQ to review potential warranty coverage.
- If outside warranty period: Seek professional guidance to repair the issue and ensure proper drainage. For minor water stains: Clean the area with a deck cleaner or oxygen bleach to remove discoloration. For pooling issues: Adjust the slope to ensure adequate water runoff or install drainage solutions. Replace water-damaged boards as needed and reseal with a waterproof coating.
5. Low Water Pressure in the Flush

Warrantability:
- Discoloration due to UV exposure or weathering is typically not covered, as regular application of stains or sealants is considered part of maintenance.
Repair Solution:
- If within warranty period: Reach out to serviceQ for warranty evaluation.
- If outside warranty period: Sand and reseal discolored wooden boards with UV-resistant stain or coating. For composite decks with fading, consult the manufacturer about refinishing options or cleaning recommendations that restore surface integrity.
