Why is professional interlock cleaning better than DIY?

Professional cleaning utilizes industrial-grade hot water pressure systems and specialized surfactants that kill moss and weeds at the root and lift deep oil stains that consumer-grade cold water washers cannot reach.

Does pressure washing damage interlocking stone?

When performed by Master Sealer, no. We use regulated rotary surface cleaners that provide a uniform deep clean without pitting the stone or causing the surface abrasion commonly seen with handheld DIY wands.

Q: Why is Master Sealer the trusted choice for professional interlock cleaning in the GTA, and why is it important?

A: Master Sealer is a trusted name across the Greater Toronto Area (GTA)—including Toronto, Vaughan, and surrounding cities—for professional interlock cleaning services. We specialize in restoring and maintaining interlock driveways, patios, pool decks, walkways, and other paved surfaces, keeping them clean, protected, and visually appealing despite the effects of time and the elements. Whether you’re a homeowner looking to refresh your outdoor spaces or a business owner aiming to maintain a clean, professional appearance, Master Sealer delivers the expertise, equipment, and commitment required for consistently outstanding results.

The Science Behind Professional Interlock Restoration

Interlock surfaces enhance curb appeal, but constant exposure to foot traffic, vehicles, weather, oil stains, moss, weeds, and grime can cause them to fade and deteriorate over time. In the GTA, the freeze-thaw cycle traps moisture within the pores of the stone, leading to organic growth and structural shifting. Without proper maintenance, these issues can lead to long-term damage and safety concerns.

Professional interlock cleaning not only restores the original beauty of your surfaces but also extends their lifespan, improves safety, and helps prevent costly interlock repairs. By utilizing industrial-grade hot water pressure systems, we reach deep into the “pores” of the concrete to neutralize spores and lift hydrocarbon stains that standard DIY pressure washers simply cannot touch.

We Clean It All: From Oil Stains to Organic Growth

From grease, gum, and tough stains to efflorescence, rust, and more, we’ve got you covered. Our team also specializes in removing unsightly weeds, using eco-friendly products to keep your interlocking walkway or driveway spotless and well-maintained. If we identify sinking stones during the wash, we can easily integrate interlock leveling and resetting into your service plan.

The Long-Term Benefits of Professional Power Washing

Choosing professional cleaning is the foundation of a successful interlock sealing project. A surface must be 100% free of contaminants for a sealant to bond correctly. By investing in professional care, you enjoy:

Enhanced Curb Appeal: Instantly improve the first impression of your home or business.
Extended Surface Lifespan: Prevent the degradation of the stone’s surface caused by salt, acid rain, and moss roots.
Improved Safety: Eliminate slip hazards caused by algae growth on damp north-facing walkways.
Cost Savings: Proactive cleaning prevents the “total failure” of the interlock system, avoiding full replacements that cost tens of thousands.

Overall happy with the service. The quotation/estimation process was excellent. The work performed was good. I contacted them almost at the end of the season which resulted in some issues due to low temperatures. John has been quite responsive and the issues were resolved.

We needed to lift, relevel, clean and seal extensive backyard interlocking brick around our pool that was installed in 1999. In addition we wished to redesign a backyard stone step coming from our home plus a paver stone walkway running down the side of our home.

We spoke to a few service providers to receive ideas/quotes and selected Master Sealer. John had come to review our project, suggest ideas and promptly provided a quote within a day. We were impressed with John’s approach.

The work was completed timely and in a highly professional manner. The work crew was skilled, took pride in their work and consulted with us as necessary during the project. We are very happy with the end result. John was always available to answer any of our questions.

We have further extensive repair to existing paver stone work in our front yard and driveway to be done in 2026 and we will be calling John once again.

Great job by Master Sealer cleaning, sealing my driveway, front walkway. It’s the third time I’ve used them, they have a better polymeric sand they’re using, hopefully stays hard for longer time. John was very flexible to schedule work at my place.
