We Fix Fences
Published in Coquitlam • 4 min read
Coquitlam's location at the foot of the Coast Mountains makes it one of the wetter communities in the Lower Mainland. Moisture rolls off the mountains, rainfall totals exceed 1,500 mm annually, and surfaces that don't get regular sun exposure become green with moss and algae within a single season. Lean On Me's Coquitlam power washing team cleans fences, driveways, decks, and siding using professional equipment and the right detergents for each surface type — delivering a thorough clean that protects your property and extends the life of your outdoor surfaces.
climate impact
Coquitlam's higher elevations — Burke Mountain, Westwood Plateau, and the slopes above Austin Avenue — see more rain and fog than the valley floor. This persistent moisture keeps biological growth thriving from September through May. Shaded driveways in Coquitlam's mature tree-lined neighbourhoods like Ranch Park and Maillardville can develop dangerous algae films within weeks of a prolonged rain period. Cedar fences in low-light backyard spaces grow moss thick enough to hold moisture and begin softening the underlying wood. Without periodic power washing and moss treatment, these surfaces degrade significantly faster than they should — shortening the lifespan of expensive fence and decking materials.
common issues
Common Coquitlam power washing requests include: moss-covered cedar fences in Ranch Park and Austin Heights, algae-slick driveways in Maillardville's older housing stock, mildew-stained wood decks in the tree-rich residential backyards of Blue Mountain Park area, concrete retaining walls covered in moss (especially common on Coquitlam's many sloped properties), and post-construction cleaning on new Burke Mountain homes where construction dust and surface contamination needs removal before surface treatments are applied.

Frequently Asked Questions
Q: Is annual power washing necessary in Coquitlam?
a
Yes, especially for properties with tree coverage or north/west-facing surfaces. Coquitlam's rainfall and mountain moisture make biological growth a near-constant issue that annual cleaning keeps in check.
q
Can you power wash the concrete retaining walls common on Coquitlam slopes?
a
Yes. Retaining wall cleaning is a regular service for Coquitlam's many sloped properties. We adjust pressure to avoid mortar erosion while removing all surface growth.
q
How do you treat moss so it doesn't come back quickly?
a
After power washing, we apply a biodegradable biocide that kills moss spores remaining in surface pores. This significantly slows regrowth compared to washing alone.
q
Do you service all Coquitlam neighbourhoods?
a
Yes. We service all Coquitlam areas including Burke Mountain, Westwood Plateau, Ranch Park, Maillardville, Austin Heights, and all Tri-Cities adjacent communities.
