Our driveway looked 10 years old before they showed up — now it looks like it was just installed. Pressure wash plus new poly sand made a huge difference.
Had oil stains under the cars I thought were permanent. They came out in an afternoon. Wish I'd called sooner.
Pool deck was green with moss. They cleaned it, sealed it, and it's still spotless a year later.

View project Techniseal and Alliance Gator cleaners, polymeric sand, and sealers. Wrong PSI blows joint sand out and pits pavers. We dial in PSI per paver type.
Kanata. We clean interlock driveways, walkways, and pool decks across Kanata Lakes, Bridlewood, Morgan's Grant, Beaverbrook, and Katimavik. Most Kanata clean + re-sand jobs land between $600 and $1,400 for a standard double driveway.
Barrhaven. Clean and re-sand work across Half Moon Bay, Stonebridge, Longfields, Davidson Heights, Chapman Mills, and Strandherd. The newer Barrhaven subdivisions see a lot of efflorescence haze — we treat it as part of the wash.
Orleans. Pressure wash and stain removal across Avalon, Fallingbrook, Chapel Hill, Convent Glen, and Queenswood Heights. Older Orleans driveways often have heavy weed growth in the joints — full poly sand re-sand is usually the right fix.
Nepean. Clean, re-sand, and oil stain treatment across Centrepointe, Tanglewood, Crestview, and Trend-Arlington. Mature Nepean tree canopy means a lot of organic stain and moss work.
Stittsville. Clean and re-sand across Jackson Trails, Crossing Bridge Estates, and Amberwood. Larger lot sizes in Stittsville mean longer driveways — we quote by area, not by visit.
Gloucester. Clean, stain removal, and re-sand across Beacon Hill, Blackburn Hamlet, and Hunt Club. Gloucester driveways exposed to road salt typically need a clean every 2-3 years to keep joints tight.
Manotick. Estate driveway cleans across Mahogany, Manotick Estates, Long Island, and Manotick Village. Circular drives and large patio surrounds are a regular part of our Manotick work — $1,200 to $3,000 range.
Riverside South. Clean, re-sand, and sealing prep across Honey Gables and the Riverside South village. Newer pavers here usually only need a light wash and fresh poly sand.
Centretown. Tight-access cleaning across the Golden Triangle and Centretown West. We bring smaller equipment for downtown laneways and condo courtyards.
Westboro. Clean, rust and efflorescence removal across Westboro Beach, Highland Park, and McKellar Park. Older Westboro patios benefit from a clean + reseal package every 3 years.
Alta Vista. Clean, weed treatment, and re-sand across Heron Park, Faircrest Heights, and Playfair Park. Mature trees mean heavy leaf staining — we treat tannin spots as part of the wash.
The Glebe. Heritage-friendly cleaning across the Glebe and the Old Ottawa South border. Narrow lots and shared walkways — we coordinate with neighbours on access.
Interlock cleaning in Ottawa typically costs $0.50 to $1.25 per square foot for a deep pressure wash plus polymeric sand re-sand. Stain removal (oil, rust, efflorescence) and full sealing are quoted as add-ons.
Most Ottawa homeowners clean and re-sand interlock every 2 to 3 years. Driveways exposed to road salt and heavy traffic may need it more often than backyard patios.
Yes. We treat oil, grease, BBQ drip, rust, and efflorescence with targeted cleaners. Old stains may need multiple passes but most come out completely.
Not at the right PSI. Wrong pressure blows joint sand out and pits paver faces. We dial PSI to the paver type and finish with fresh polymeric sand.
Yes — cleaning without re-sanding leaves joints empty and weeds come right back. Our standard package includes a full polymeric sand re-sand.
Yes. We pull out existing growth, treat the joints, and re-sand with polymeric sand which hardens and blocks future growth for years.
Yes — most pavers come back to their original colour after a deep clean. For long-term colour depth and protection, add a sealer the same week.
Cleaning happens first; sealer is applied a few days later once pavers are fully dry. We schedule both visits when you book the package.
April through October, on dry days. We avoid cleaning right before rain so the new polymeric sand has time to set.
Yes. We clean interlock across Ottawa, including Kanata, Barrhaven, Orleans, Nepean, Stittsville, Gloucester, Manotick, Riverside South, Centretown, Westboro, Alta Vista, and The Glebe.
