How To Repair Flagstone Patio Cracks

How Do I Fix It

Flagstone Joint Repair

So, what causes a patio to settle in the first place? Prior to the concrete being installed, the ground is prepared by compacting the earth underneath with heavy machinery. In most cases, this compacted surface will either be gravel or at least covered with a layer of gravel. These steps are taken to prevent the ground from settling under the weight of the patio installed above. However, sometimes settlement is inevitable due to weather conditions, namely rain water washing away the soil underneath. Also, sometimes the compacting is not done correctly or thoroughly enough.

How Much Does Professional Patio Installation Cost

If your patio is in terrible condition, it may be beyond repair. In this case, you will need to completely replace the patio, which can be costly. Although this will require an investment, you can be confident that your new patio will look amazing and be durable. Whatâs more, if properly maintained, a new patio can really stand the test of time.

Sound tempting? You can choose to lay your new patio yourself using our how to lay a patio guide or hire a professional. Generally, you can expect to pay £25 â £75 per metre square of patio for professional installation, although this will vary depending on your circumstances.

How To Fix Cracks In Concrete Decks

As the old saying goes, “there are two types of concrete decks. One has a crack, and the other will have a crack.”

In our work, we have seen more cracks in concrete decks that one could count. Early in the life of a concrete deck, cracks can occur when concrete expands and contracts with weather conditions, and when expansion joints are not well positioned. Cracks in concrete decks and patios can also appear when the soil underneath the concrete slab erodes. This erosion can be the result of settling soil over time, water movement, nearby construction or more. Due to its stiffness, concrete does not flex with the changing ground conditions. If the slab can’t carry its own weight in a section, a crack occurs. Expansion joints reduce the likelihood of cracks, but cracks can’t be completely avoided in most concrete patios or decks.

Most home and property owners are unhappy with traditional ways to “fix” cracks: mostly the cracks are patched up with filler material. This material – if used correctly – may prevent further cracking by keeping water and ice out of the crack. However, further cracking due to soil and gravel shifting underneath can’t be prevented by this method. Also, a 100% texture and color match is usually not possible, and so patching up cracks becomes very unsightly. Oftentimes a patched up crack looks just as bad – or worse – than the crack itself!

Labor Costs To Repair A Patio

Labor costs for patio repairs vary from $50 to $150 per hour, depending on various factors like your location and the skill and experience of the workers. Some repair workers charge by the hour, while others have set fees for certain jobs, such as filling a crack and repairing a damaged door.

Workers often have minimum fees of around $50 to $75 for each job and may have call-out fees of a similar price to visit your property and inspect the problem. The call-out fees are typically waived if you hire the worker for the repair. However, you may have to pay extra for urgent repairs, and you may need to pay travel costs for workers to get to your home if you live somewhere remote.

Option : Replace The Whole Thing

The first way most homeowners think of to address their settling patio is to simply replace it. Seems simple enough, right?

But this method is not so simple. Replacing the entire patio will first require you to remove any furniture you may have on the surface, as well as any plants or landscaping which may be along the borders. Then youre in for lots of labor, new materials, and foot traffic through your property. Even though it seems like the most obvious choice, replacing the whole patio is the most expensive and time consuming option on the table. So what else can you do?

Patio Door Repair Price

Repairing a patio door repair ranges from $50 to $300. The total cost of door repair depends on the damage and amount of work needed to fix it.

    Cost To Pressure Wash A Patio

    The cost to pressure wash a patio that measures 50 sq.ft. averages $50 to $75. You can save money by doing this yourself if you own or borrow a pressure washer. Be careful when pressure washing patios because the pressure can do more harm than good to certain stones and other materials. If you want to get rid of stains, marks, weeds, and moss, you may want to call in a professional to pressure wash your patio.

    Additional Considerations And Costs

    • Warranty. Some patio installations come with warranties, and large repairs also come with warranties of around one year. Check for the warranty coverage and ensure you know the details to make a claim.
    • Ask for different quotes. Patio repair prices vary from one worker or company to the next. One company might quote a certain amount for something like fixing a crack, and another company might offer to do the same job for 75% of that price. Get multiple quotes for the best value.
    • License. It is always best to work with licensed professionals for any home or garden repair. Check the licensing status of workers or companies you hire.
    • Lifespan. The average lifespan of a patio is around 25 to 50 years, depending on materials, climate, and maintenance. If the patio is several decades old, the risk of problems like cracks and sunken pavers is higher.
    • Permit. For minor patio repairs, permits are not usually needed. However, permits may be needed for larger jobs like repaving, replacing large sections, or installing a new cover or awning. Check with your local building authority for more information.

    Even When Your Bucket Is Full Of Dirty Looking Water Thats No Problemjust Dip Squeeze That Sponge Dry And Then Use It One Corner At A Time

    Then, I like to actually sponge off the mortar joint itself. This will smooth down any trow marks and leave you with a much more consistent looking mortar joint.

    Sponging down the joint itself will also fill minor gaps that you may leave behind with the trow. Look, Im pretty good with a trowbut still, little tiny spots can get left, little voids, about one quarter the size of a match headlittle spots, usually along the edge of the stone, not in the middle of the joint. These are spots where water can infiltrate, and cause a mortar joint to fail, sometimes within just a few years. Worse still, that water could even get underneath your flagstones, cause thing to pop up and come loose.

    Im not really sure how many masons use a sponge technique like I do. What I do know however is that when I come in to repair these jobs, I always find little tiny gaps in the mortarlittle tiny gaps like the ones that I myself sometimes leave behind with my trowbut that I always correct, with the sponge.

    ***again, the sponge is used a bit less, if you go with a super-dry method.

    To replace missing stones, youll need stones of similar size and thickness to what already exists. You may have to do some chipping to make the new pieces fit the voids. Do this slowly and whittle away from the edge so you dont remove too much material.

    Once the stones are dry fit, youre ready to mix up the mortar. Were using a pre-mixed mortar that only requires the addition of water. Remove the stones and apply some mortar each location. Then replace the stones, pressing them into the mortar.

    To replace missing mortar around the existing stones, mix the mortar a little thinner so it runs into the cracks when applied to the joints. As the mortar begins to dry, youll want to clean it off the face of the stones using a mason brush or a sponge along with a light spray from a garden hose.

    When the mortar is completely dry, clean the entire surface with a masonry or stone cleaning solution. This is necessary to prepare it for the application of a sealer.

    Applying the sealer will protect the stones and the mortar so that the walkway remains safe and attractive for a long time.

    Freezing Thawing Causes Flagstone Mortar To Tilt Crack


    New York Times News Service

    Flagstone steps, walkways and patios need occasional maintenance and repair, usually to renew the mortar between the stones or in the case of stones laid without mortar, to level those that have tilted or sunk.

    The work is not complicated, but it can be strenuous if moving stones is required.

    Areas of cracked mortar between flagstones should be repaired.

    Moisture seeping into cracks and repeatedly freezing and thawing will eventually cause further cracking, and weeds sprouting in the fissures can do the same thing.

    For protection when working with mortar and stone, wear goggles and thick gloves.

    To repair cracked mortar, use a cold chisel and either a large ball-peen hammer or a small sledgehammer to chip away the damaged pieces. Strike with light to moderate blows. Stop when you reach sound mortar. Then brush the area clean with a whisk broom.

    Soak the chiseled area and surrounding stones with water from a garden hose while you prepare fresh mortar for a patch. Mix the mortar according to the manufacturer’s directions with a mason’s trowel or large putty knife.

    Properly mixed mortar should be neither soggy nor crumbly. One way to test it is to slice a small mound, about two cups’ worth, down the center. If the edges of the two slices collapse, the mixture is too wet if they crumble, the mixture is too dry.

      I am guessing that you live in a climate that has multiple freeze/thaw cycles. everything moves with the weather conditions – expanding and contracting. additionally, if water somehow finds its way into the mortar or stone, it could expand when frozen and aid in the hairline cracks in your mortar.

      I would repair the joints the best I could, adding a liquid latex to the mortar mix. this will allow more flexibility. then I would seal the whole thing with a waterproofer like: “Gloss n’ Guard” or “Weather Seal Siloxane”

      this will keep the water out of your flagstone and joints.

Leaving the patio or walkway in this condition will lead to stubbed toes, leaning furniture, and an overall undesirable place .

    Cracks in a concrete patio are not just unsightly, they also invite weed growth, collect debris, and can be a trip hazard.

In some cases, one side of the crack rises higher than the other sidea condition called lippage that can lead to trips and falls. When cracks get out of control, the only recourse is to demolish and rebuild your patio.

    Cracks in a concrete patio can be repaired quickly with simple methods and inexpensive materials. This fix effectively blocks weeds, cures the debris problem, and prevents further damage to the patio for years.

    Option : Polymer Slab Lifting

    The most recent advancement in patio repair is polymer slab lifting, which serves as an alternative to mudjacking that offers a lighter material and fewer followup problems. Similar to mudjacking, the polymer material is injected into holes and cracks in the patios slabs, and then pumped underneath the surface of the patio, filling all voids and binding with the soil. As the material solidifies, it expands at a rapid rate, and so lifts the concrete surface to where it needs to be.

    Unlike mortar mixtures, the material used in polymer slab lifting is surprisingly light, yet equally strong. The cleanup is also quick, as there is no excess, muddy material to have to wash away or clean with water. Once all the lifting is complete, all thats left to do is a simple process of sealing cracks and adding the finishing touches to the patios newly filled and leveled surface.

    Keep in mind, for patios composed of numerous smaller stones or pavers, mudjacking and polymer slab lifting will not always be applicable, as it is not possible to lift such small pieces uniformly. Different issues will call for different solutions, and so it is always advisable to call a local professional for large patios or walkways which may be facing settlement issues. Quotes should generally be free of charge, and youll then have a good idea of the time frame and cost involved for getting your space back into tip-top shape.
