PROMO: is here
Cracked, loose, or sunken stone can let in water and turn a walk into a trip hazard. We assess steps, porches, patios, walkways, and exterior stonework in Toronto and across the GTA. An on-site laser measurement comes before an itemized estimate, because a phone quote cannot show whether the problem is a joint, bedding, drainage, or movement below.
Built on trust and quality.
Trusted by Toronto Homeowners & Builders Since 2010






A cracked joint may need repointing. A rocking flagstone may need to come up so the bedding below can be addressed. We explain the difference before pricing.
Replacement stone and mortar cannot be made identical to aged material. We show where a repair will sit and aim to match the existing work as closely as practical.
Toronto freeze-thaw and wet conditions affect exterior mortar work. We give an approximate installation date based on material availability, weather, and the type of repair.






Point At the Stone Repair You Need
You may know what is wrong before you know the repair term for it. Pick the signs that match what you are seeing, then tell us where and when it started. Antex will measure the work on site and bring the price to the actual job.
We assess the stone, joints, and visible movement at the visit. If a stone must be lifted and reset rather than pointed over, that goes into the recommended scope.
Our itemized estimate separates materials and labour and is valid for two weeks. The price changes only when you change the scope or materials, with no hidden charges.
We review the existing material and the proposed replacement area with you. Stone is supplied and custom cut by our suppliers, so availability can affect the closest practical match.
We check the damaged area for signs that water is entering joints or collecting near the house. Where applicable, we confirm the relevant Ontario Building Code requirement on site.
Floors and planting are covered while we work, dust is kept down, and old material and waste are removed. We also discuss access to the affected steps or walkway before starting.
Mortar over a loose stone can hide movement for a while. When water remains below, another freeze-thaw cycle can open the same area again.
A quote that says only stonework repair leaves room for disagreement over stones, joints, bedding, waste, and the work around the damaged area.
Older stone has weathered, and mortar changes colour over time. A new piece may stand out if its location and practical match are not discussed first.
Snowmelt and heavy rain can enter open joints or sit beneath a surface. In Toronto, repeated freezing and thawing can lift stone and crack mortar.
Dust, broken mortar, and removed stone can affect planting and access. An unsafe step or walkway also needs a clear plan while work is underway.
The right scope depends on whether the damage is limited to a joint, a few loose pieces, or a base that has moved. We assess the area and access on site, including narrow side yards and rear-yard material routes. Toronto snowmelt, road salt, and freeze-thaw exposure shape the method and timing for exterior repairs.
For flagstones that rock, sink, or have open joints. Flagstone repair can address a damaged section without assuming the whole patio must be replaced.
For cracked, loose, or separating entrance pieces. Stone step repair starts with the condition of the step and the material below it.
For worn joints, shifted stone, and localized surface damage. The scope identifies the affected section so you can compare repair with broader replacement.
For cracked mortar or loose exterior facing stone. Marble repair and granite repairs need an on-site look because the material and failure location change the approach.
For visible damage around stone foundation areas. If you need to fix stone foundation damage, we inspect the accessible stone and explain the repair scope before pricing.
We inspect the failed area and measure on site before recommending repair or replacement. That gives you a scope based on the actual condition, not a photo or phone guess.
Once approved, our suppliers provide stone custom cut to the needed measurements. Material availability and exterior weather affect lead time, so we keep you updated.
We complete the agreed work, remove waste, and check the finished area with you. The final walkthrough happens before the remaining balance is paid.
These completed stone repair projects show the symptoms homeowners brought to us, the exterior surfaces involved, and when the problem became apparent. Each card records the choices behind a practical repair for Toronto's wet, freeze-thaw conditions.
A settled patio area was lifted and reset to remove trip points and restore a continuous walking surface.
Loose walkway stones were reset so the route no longer shifted under regular foot traffic.
Failed joints at an entrance landing were renewed to close open gaps between otherwise sound stones.
A split porch stone was replaced to restore an even approach at the front door.
Flaking stone around a pool deck was repaired where repeated wetting had damaged the exposed surface.
Separated edge stones were realigned to bring a garden path back to its intended line and width.
Clear communication and careful site checks made the repair straightforward from start to finish.
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.
We inspect visible stone, joints, and movement before recommending a repair. That helps separate a localized issue from work that may need a broader scope.
Materials and labour are split out and the estimate is valid for two weeks. It moves only if the scope or materials change.
One dedicated point of contact manages your job from the first visit to the final walkthrough. You receive daily updates while the project is running.
Installation labour is covered by a written workmanship warranty in the Construction Agreement. Manufacturer warranties on supplied materials are passed through.
You should know what is being repaired, when work is expected, and what changes if the site reveals a different condition. Our process keeps the scope visible from the first visit through cleanup and handover, without asking you to decide at the door.
Your project manager visits, laser-measures the damaged area, and reviews access and visible conditions. We send an itemized estimate within one to two business days. It covers materials and labour, remains valid for two weeks, and no material is ordered until you approve it.
After approval, we arrange stone supplied and custom cut by our suppliers for the repair scope. We provide an approximate installation date, plus a written timeline where one applies. Exterior work depends on material availability and weather, and we call when the date moves.
We cover nearby floors and planting, keep dust down, and remove old material and waste. The project manager checks the completed work and walks the area with you. The remaining 10% payment is due after that final walkthrough, not before.
Send photos of the cracked, loose, or sunken area, then arrange a free on-site measurement in Toronto or across the GTA. We'll inspect what is accessible, explain repair versus replacement, and send an itemized estimate within one to two business days. There's nothing to sign at the visit, and nothing is ordered until you approve the scope.
