5-Star Google Review
“Working with Dean and DinoMac is always a pleasant experience. Dean is so good at what he does, anytime a client asks about masonry work, I always refer DinoMac Masonry. The first project we worked on together I had hired another mason to do some chimney repairs above the roof line. The work that was completed by the other mason was below standard, the chimney flashing was poorly done, and improper mortar was used. Knowing of Dean and his professional background, I quickly contracted Dean to make it right for the customer for me. The results were astounding.”

What Masonry Restoration Means
Restoration is about extending the life of existing masonry.
Masonry restoration can involve far more than repointing. Depending on the condition of the wall, it may include replacing individual bricks or stones, rebuilding unstable sections, repairing openings, correcting water-entry details or removing incompatible previous repairs.
The common goal is to retain the sound masonry and repair the areas that are no longer performing properly.
That approach is often more economical and more respectful of the building than replacing large areas simply because a smaller portion has deteriorated.
The First Question
Why did the masonry fail?
Water, movement, freeze-thaw exposure, poor previous repairs, unsuitable mortar, failed flashing and drainage problems can all produce damaged joints and masonry units.
If the cause remains, a new surface repair may eventually fail in the same place.
Repointing
Mortar joints are a working part of the wall.
Repointing renews deteriorated mortar while keeping sound brick, block or stone in place.
Remove Failed Mortar
Loose and deteriorated mortar must be removed to sound material so the new mortar has adequate depth and a solid surface to bond against.
Use Compatible Mortar
Strength, vapour permeability, aggregate and exposure all matter. A mortar that is too hard can create new problems in softer brick or stone.
Finish the Joint Properly
Joint profile affects both appearance and weather resistance. The finish should suit the masonry and, where appropriate, match the surrounding original work.
Mortar Compatibility
The strongest mortar is not automatically the best mortar.
Mortar is often intended to be more forgiving than the masonry units around it. It accommodates small amounts of movement and provides a path through which moisture can migrate.
When an older or softer brick or stone wall is repointed with mortar that is excessively hard or dense, stress and moisture may be redirected into the masonry itself.
A proper restoration considers the wall that already exists rather than choosing mortar solely on compressive strength or colour.
Matching Mortar
Appearance matters, but performance comes first.
Colour, sand, texture and joint profile can all be adjusted to produce a repair that blends with surrounding masonry.
The visual match is important, but the mortar still has to behave properly with the brick or stone over many freeze-thaw cycles.
Brick Restoration
Damaged brick does not always mean rebuilding the whole wall.
Individual bricks can crack, spall or lose their face while the surrounding masonry remains serviceable.
Where the wall remains stable, damaged units can often be removed and replaced selectively. The replacement brick should be chosen with attention to size, colour, texture and physical properties.
Repointing can then be used to renew the surrounding joints and tie the repair visually into the existing wall.
Stone Restoration
Stone walls have their own logic.
Natural stone restoration requires attention to how each stone bears, how the joints are filled and how the wall manages moisture.
Repair may involve repointing, resetting loose stones, replacing individual failed units or rebuilding a section that has moved.
DinoMac's background in natural stone masonry is particularly useful where the repair has to blend into existing stonework rather than look like an obvious patch.
Natural Stone Masonry
Cracking & Movement
A crack is a symptom. The direction and pattern can help explain the cause.
Some cracks are localized and repairable. Others indicate ongoing movement that should be understood before the joint is filled.
Stair-Step Cracking
Cracks following mortar joints can be associated with movement, settlement, openings or other changes in the wall.
Cracks Through Units
Cracking through brick or block can indicate stresses greater than the joints alone are able to accommodate.
Recurring Cracks
If a repaired crack repeatedly opens, the movement or moisture condition responsible may still be active.
Significant movement, structural displacement or uncertainty about load-bearing conditions may require structural engineering input before the masonry repair is finalized.
Selective Rebuilding
There is a point where repointing alone is no longer enough.
If masonry has bulged, shifted, separated or lost enough joint material to compromise stability, repointing the face may not restore the wall.
In these situations, a localized area can sometimes be dismantled carefully, sound units salvaged and the section rebuilt.
Selective rebuilding allows the failed portion to be corrected while preserving sound surrounding masonry.
Repair versus rebuild
The decision is based on stability, amount of deterioration, cause of movement and how much sound material remains.
The goal is neither to rebuild unnecessarily nor to preserve masonry that is no longer capable of performing safely.
Previous Repairs
Sometimes the old repair becomes part of the new problem.
Restoration work frequently involves correcting earlier repairs that were intended to be permanent but were not compatible with the masonry.
Surface Pointing
Thin mortar smeared over the face of deteriorated joints may look improved temporarily but provides little durable bond to the wall behind it.
Overly Hard Mortar
Hard repair mortar can contribute to brick or stone deterioration when it is significantly less forgiving than the original masonry.
Coatings & Sealers
Some coatings can trap moisture or hide deterioration until the underlying masonry has become worse.
Water Management
A masonry repair will only last as well as the wall manages water.
Failed flashing, horizontal ledges, open caps, damaged sills, poor drainage and recurring roof runoff can all feed water into masonry.
On PEI, repeated freeze-thaw cycles can then turn small areas of saturation into spalling brick, failed joints and larger repairs.
Repointing restores the joint, but correcting the water-entry route is often just as important to the durability of the work.
Look beyond the damaged joint.
✓Flashing and roof junctions
✓Sills, caps and copings
✓Downspouts and drainage
✓Cracked horizontal surfaces
✓Vegetation and trapped moisture
Cleaning & Efflorescence
Cleaning should remove the stain, not the surface of the masonry.
Dirt, biological growth, soot and mineral deposits can change the appearance of brick and stone over time.
Efflorescence, the white mineral deposit sometimes seen on masonry, is also evidence that moisture has moved through the material and carried soluble salts to the surface.
Cleaning should begin with the least aggressive method likely to work. Excessive pressure or unsuitable acid cleaners can damage mortar, soft brick and some natural stone.
Before cleaning
✓Identify the staining
✓Repair active water entry
✓Test a small area first
✓Use masonry-appropriate products
✓Avoid unnecessary surface damage
Weather & Curing
Good mortar needs suitable conditions after it leaves the mixer.
Fresh mortar can be affected by freezing temperatures, intense heat, direct sun, wind and heavy rain.
In hot or dry conditions, mortar may lose moisture too quickly. In cold conditions, freezing can interfere with proper curing unless the work and materials are suitably protected.
Scheduling, shading, damp curing, heating or enclosure may be needed depending on the season and type of work.
PEI Conditions
Spring and fall are often excellent restoration seasons.
Summer can also be productive, but exposed walls may require extra care during hot, sunny or windy periods. Suitable conditions matter more than simply choosing a date on the calendar.
For Building Owners & Property Managers
Restoration is easier to budget when masonry is maintained before it becomes an emergency.
Large buildings often contain several different levels of masonry deterioration at the same time.
Priority Repairs
Loose masonry, active leaks, exposed chimneys, parapets and unstable sections should generally be considered before cosmetic maintenance.
Phased Work
Large restoration projects can often be divided into manageable sections so the highest-risk areas are completed first.
Preventative Maintenance
Repointing joints and correcting water entry early can protect a much larger area of otherwise sound masonry.
Heritage Restoration
Older buildings sometimes require an even more specialized approach.
Historic brick and stone can contain softer masonry, lime-rich mortars, traditional joint finishes and wall systems that handle moisture differently from modern construction.
For churches, schoolhouses, estates and other historic properties, repair methods should preserve original material and respect the building's existing construction.
Heritage Masonry Restoration
Why DinoMac
Restoration rewards patience, judgment and attention to detail.
DinoMac combines generations of family stonemasonry knowledge with modern restoration tools and years of repair experience across Prince Edward Island.
Our approach is to understand why the masonry failed, preserve sound material where practical and make the repair visually and physically compatible with the wall around it.
DinoMac is PEI's highest-rated masonry contractor on Google, with a long-standing island-wide reputation for masonry repair, natural stone and restoration work.
What a good repair should do
Stop the active deterioration, protect the remaining masonry and avoid creating a new problem with the repair material itself.
Masonry Restoration Across PEI
Repointing and masonry repair from a PEI-based specialist.
DinoMac is based in Bonshaw and serves masonry restoration projects throughout Prince Edward Island, including Charlottetown, Stratford, Cornwall, Summerside and surrounding rural communities.
PEI exposure makes moisture management especially important. Rain, wind, salt in some coastal locations and repeated freeze-thaw cycles can accelerate mortar loss, spalling and deterioration once water begins entering a wall. Durable restoration therefore looks beyond the damaged joint to the water path, movement and previous repairs around it.

Frequently Asked Questions
Masonry restoration questions
What masonry restoration services does DinoMac provide in PEI?
DinoMac provides masonry restoration across Prince Edward Island, including brick, stone and block repointing, mortar matching, spalled or damaged unit replacement, selective rebuilding, repair of failed previous work, crack-related masonry repairs and correction of deterioration associated with water entry.
How do I know whether masonry needs repointing or rebuilding?
Repointing may be appropriate when the masonry units and wall remain stable but the mortar joints have deteriorated. Rebuilding becomes more appropriate when masonry has bulged, shifted, separated, lost stability or contains widespread unit damage. Some projects need a combination of repointing and localized rebuilding.
What is masonry repointing?
Repointing is the removal of deteriorated mortar from masonry joints and replacement with new mortar that is appropriate for the existing brick, stone or block. The goal is to restore the joint while preserving sound masonry around it.
How much old mortar should be removed when repointing?
Enough deteriorated mortar should be removed to reach sound material and provide adequate depth for the new mortar to bond properly. The required depth varies with the joint, masonry and condition, so a single fixed depth is not appropriate for every wall.
Can new mortar be matched to old mortar?
A restoration mortar can be selected to work with the existing masonry and can be adjusted for colour, aggregate and joint appearance. Compatibility in strength and moisture behaviour is more important than colour alone.
Is tuckpointing the same as repointing?
The terms are often used interchangeably, but technically repointing means renewing deteriorated mortar joints. Traditional tuckpointing is a decorative jointing technique that uses contrasting mortar lines to create the appearance of very fine joints.
Can cracked or spalled bricks be repaired individually?
Often, yes. If the surrounding wall remains sound, individual damaged bricks or stones can sometimes be removed and replaced without rebuilding the entire area.
Why does repointed mortar sometimes fail again?
Recurring failure can result from water entry, movement, incompatible mortar, insufficient joint preparation, poor curing or an unresolved building detail such as flashing or drainage. The cause should be addressed along with the joint repair.
Can you repair a wall that has been patched badly before?
In many cases, yes. Previous hard mortar, shallow surface pointing, incompatible patches and failed coatings can often be removed selectively so the underlying masonry can be repaired more appropriately.
When is masonry restoration better than rebuilding?
Restoration is usually preferred when enough original masonry remains sound and stable to justify preservation. Rebuilding becomes more appropriate when movement, widespread deterioration or loss of stability makes localized repair unreliable.
Before Repointing or Rebuilding
Identify what failed and what is still worth keeping.
Restoration works best when the repair responds to the material, moisture and movement rather than simply covering the visible damage.
Repointing
What is proper repointing?
See how joints should be opened, prepared, filled, tooled and cured.
Mortar
What mortar should be used on older masonry?
Learn why strength, permeability and compatibility matter before choosing a mix.
Brick
Why are my bricks flaking?
Understand how moisture, freeze-thaw, coatings and incompatible mortar can contribute to spalling.
Cracks
What do masonry cracks mean?
Use pattern, location, displacement and change over time to understand what a crack may be telling you.
