PROMO: is here
Sunken stones, open joints and rocking steps can worsen after another Toronto freeze-thaw cycle. We assess patios, walkways, porches and steps on site, then send an itemized estimate with materials and labour split out. We don't quote by phone because the cause may be a loose stone, a failed base or water moving below it.
Built on trust and quality.
Trusted by Toronto Homeowners & Builders Since 2010






A stone that rocks may need more than fresh mortar. We assess the bedding, base and drainage path first, because water below the surface can lift and sink flagstone through Toronto winters.
Your project manager laser-measures on site and explains what is visible before work starts. The itemized estimate separates materials and labour, so you can compare repair work with replacement work.
Exterior work can continue in winter when weather and the job type allow. Temperature and material availability affect timing, so we give an approximate installation date and call if it moves.






Point At the Flagstone Problem You Have
Most people know what is wrong with their flagstone before they know what the repair is called. Choose the symptoms and situation that fit. Antex will review what you are seeing, measure it on site, and bring the repair price down to the details of your property.
We assess whether the trouble is isolated or below the affected area, then set out the work needed to lift, prepare and relay it. This avoids treating a moving stone as only a joint problem.
For flagstone mortar joint repair, we first check the stone and bedding around the crack. Joint treatment follows the reset work, because a stable surface gives the repair a better starting point.
Spring snowmelt and regular rain can expose poor drainage around Toronto homes. We look at the affected surface and its direction on site before recommending the scope.
Floors, walls and planting are covered while we work, and removal is planned around access. We lift only what the repair requires and cart away old material and waste.
The estimate lists materials and labour and is valid for two weeks. It changes only if you change the scope or materials, so the repair decision is clear before anything is ordered.
A lifted stone can settle or heave again when water reaches loose bedding or an unstable base. The trip edge returns after the next wet and freezing season.
Fresh mortar can hide a gap without stopping water from getting below the stone. Cracks, washout and weeds often return as the joint breaks apart.
A patio or porch that holds snowmelt can keep undermining the repaired area. Puddles beside the foundation need attention before surface work is closed.
Forcing up a loose piece can crack neighbouring flagstone or mark nearby brickwork. A small repair becomes a larger replacement scope and more disruption.
You need to know what is included when the base is exposed. Unclear scope leaves homeowners comparing a low starting number with later extras.
We repair damaged flagstone at entrances, porches, walkways and patios that meet the minimum project size of 50 to 60 square feet. Toronto's wet, freezing winters make base condition and slope important. We confirm the affected area and applicable requirements on site before work begins.
For uneven paths, loose edges and washed-out joints. It suits homeowners who want to remove trip points without replacing an entire route.
For patio stones that rock, sink or collect water. We assess whether the affected stones can be reused before recommending new material.
For worn porch surfaces and stone around an entrance. It suits older brick homes where adjacent masonry and access need careful protection.
For shifted treads and loose stones at an entry. A loose step is a safety concern, so we inspect the affected work before setting the repair scope.
For a larger area with recurring movement, open joints or drainage concerns. It suits homeowners deciding between targeted repairs and broader relaying.
We inspect the area on site because a photo cannot show how a stone moves or where water is collecting. The written estimate sets out the agreed repair work before it starts.
Existing stone is kept where it can be reused. If replacement stone is needed, our suppliers supply and custom cut it to the project requirements.
Planting and nearby surfaces are covered, waste is removed and the repaired area is checked. We complete a final walkthrough with you before the remaining balance is paid.
These completed repair scopes show how different flagstone failures are addressed across patios, walks, steps and porches. Each card records the visible problem, the surface involved and when it became apparent, with build details that matter through Toronto's wet, freeze-thaw seasons.
Sunken patio stones were reset to restore an even surface and direct water away from the house.
A rocking walkway was rebuilt at the affected stones so each step landed on a stable surface.
Washed-out joints on a garden path were renewed to close exposed gaps between the flagstone.
Drifting edge stones were reset to bring the porch perimeter back into a continuous line.
Pooling on the pool deck was corrected by resetting affected flagstone to restore surface drainage.
A split landing stone was replaced and the surrounding joints were finished to match the repaired area.
Opening gaps in a stone walkway were repaired to restore continuous joints between the walking stones.
Toronto homeowners value a clear process when winter damage leaves stonework needing attention.
Wonderful experience. Antex team installed our glass shower enclosure and it looks great. Service was fast without sacrificing quality.
Anyone can hang a panel of glass. Antex is different in four ways that show up on your invoice, your calendar, and your final inspection.
A free on-site visit lets us assess loose stone, joints, slope and access. We laser-measure the work because a phone quote is a guess.
Your itemized estimate is valid for two weeks. The price changes only when the scope or materials change, with no hidden charges.
One dedicated point of contact stays with the project from the first visit to the final walkthrough. You receive an update at the end of each working day.
The Construction Agreement includes a written workmanship warranty on installation labour. Manufacturer warranties on supplied materials are passed through.
You should know what is being repaired, when work is likely to happen and who to contact. Our stages keep the decision and the work visible, without guessing at the condition below a loose stone.
We visit the property, measure the affected area and assess stone movement, joints, slope, access and surrounding surfaces. Your itemized estimate arrives one to two business days later. It is valid for two weeks, and no materials are ordered without approval.
Where replacement is needed, stone is supplied and custom cut by our suppliers. We provide an approximate installation date and a written timeline where one applies. Material availability and weather can affect lead time, so we call when a date moves.
We cover planting, keep dust down and remove old material and waste. The project manager checks the completed work, then walks it with you before the final 10% payment. The written workmanship warranty on installation labour is included in the Construction Agreement.
If loose stone, open joints or pooling water are spreading, book a free on-site measurement in Toronto or across the GTA. We'll assess what can be reset, what needs replacement and why, then send an itemized estimate within one to two business days. There's nothing to sign during the visit, and nothing is ordered until you approve the scope.
