Foundation Crack Repair: When To Diy, And When To Worry

Welcome to the world of foundation crack repair! As a homeowner, you’ll want to stay on top of any cracks that may appear in your foundations. These can be signs of something more serious, or they may just be cosmetic issues. But either way, it’s important to know when you should DIY the job and when to call in the pros. That’s why we’ve put together this handy guide to help you determine the best course of action for your foundation crack repair.

Cracks in our foundations are more common than most people realize. While some are minor and require nothing more than cosmetic repairs, others can signal deeper structural problems that need professional attention right away. Ignoring these signs could lead to further damage and costly repairs down the line – so it pays to stay vigilant and aware of any cracks appearing in your home’s foundation.

Knowing when it’s time to DIY or call in a professional is key – but how do you decide? With this article, we aim to provide homeowners with all the information they need on foundation crack repair – from recognizing different types of cracks, assessing their severity, understanding when they need professional attention, and learning how to carry out basic repairs yourself. So let’s get started!

Understanding Foundation Cracks

It’s estimated that one in five homes have some kind of foundation damage. That’s a startling number, and it’s why understanding foundation cracks is so important. As a handyman, I’m all too familiar with the different types of foundation cracks – and when to know when it’s time to DIY or call for help.

The most common type of crack you’ll find is a vertical crack near the edge of your home’s foundation wall. These are usually caused by soil shifting over time, and often settle back down on their own. If you can fit a nickel into the crack, however, then you may need to get an expert opinion.

Hairline cracks might not seem like much to worry about – but if you see them gradually growing wider over weeks or months, that’s definitely something to be concerned about. If there are two adjacent walls with large cracks that are running parallel to each other, it’s possible your house could be experiencing structural damage and should be inspected right away.

Knowing the difference between DIY-able repairs and those that require professional help can save you headaches (and money) down the road – so stay vigilant!

Causes Of Foundation Cracks

Cracking foundations can be like opening Pandora’s box – you never know what kind of trouble you’ll face. To prevent the misfortunes of foundation damage, it’s important to understand why they appear in the first place. As a handyman, I’m here to tell you why cracks form and how to identify them.

The most common cause of foundation cracks is soil movement. Soil expands when it gets wet, and contracts when it dries out. Over time, this can cause fissures in the foundation wall or floor which can lead to more serious structural damage if not addressed. Shifting soil may also be caused by extreme weather events such as floods or earthquakes which can have devastating effects on your foundation.

Other causes include improper concrete curing during construction, or inadequate waterproofing that allows water to seep into the foundation walls and weaken them over time. Poor drainage around the house can also contribute to cracking foundations because water does not have an outlet and instead gathers around the base of your home where it eventually seeps into the ground beneath your foundation causing instability and cracking.

By understanding these possible causes, you’re one step closer towards recognizing warning signs of structural damage early on and taking action before it’s too late!

Warning Signs Of Structural Damage

Did you know that up to 90% of foundation cracks are harmless and don’t require repair? But it’s important to be able to tell the difference between normal wear and tear cracks, and those that point to structural damage. Let’s take a look at the warning signs of foundation damage.

It can be hard to determine if your crack is serious or not, but there are some key signs that should raise alarm bells. If your foundation has shifted and you notice an unevenness in the floor, this could indicate a problem with the underpinning. In addition, it’s essential to keep an eye out for any water seepage around windows or doorways, as this could point to a more serious issue with your foundation.

If you’re concerned about the condition of your house’s foundation, don’t hesitate to get it checked out by a professional handyman. Even if it turns out that no repair is needed, it’s always better to be safe than sorry! Now let’s move on and discuss how to diagnose any potential issues with your foundation crack.

Foundation Crack Diagnosis

It’s estimated that one in four homes have a foundation crack, so it’s important to know when to DIY or worry. To help diagnose the issue, let’s look at Foundation Crack Diagnosis.

The first step is to assess the crack itself. If it’s under 0.3 inches wide and not growing then you may be able to take care of it yourself with some caulk or mortar mix. However, if the crack is wider than 0.3 inches then it’s best to contact a professional as this could be an indication of structural damage.

Another indicator is the location of the crack – cracks along outside walls are usually caused by soil pressure, while cracks in interior walls could be due to settling issues or water damage from plumbing leaks. Lastly, horizontal cracks indicate significant structural problems and should be taken very seriously as these require professional repair and may need additional support for your home’s foundation structure.

If you’re unsure what type of crack you have then it’s best to consult a professional for diagnosis as taking care of a foundation issue can save you thousands down the line.

Diy Foundation Crack Repair

If you’re a handyman at heart and have been itching to do something DIY, now’s your chance! Foundation crack repair might seem like a daunting task, but with the right tools, it can actually be quite an enjoyable experience. So why not give it a go?

That said, it’s important to know when DIY is appropriate and when you should call in the experts. Repairing cracks yourself is recommended if they’re minor and don’t show signs of structural damage. If the crack is wider than ¼ inch or if you suspect that the wall has shifted, it may be best to leave it in the hands of a professional.

TIP: When inspecting cracks for possible repair, use a flashlight to get a better view of any underlying issues. This will help you determine whether you should proceed with DIY methods or schedule an appointment with an experienced contractor.

Now that we’ve got all that figured out, let’s look at what materials and supplies we need for foundation crack repair.

Repair Materials And Supplies

The materials and supplies needed to repair a foundation crack can vary depending on the type of crack. You’ll want to make sure you have everything you need before starting. Here’s what you’ll need:

First, you’ll need a caulk or sealant specifically designed for foundation repair. Make sure it’s rated for exterior use and is waterproof, as well as flexible enough to withstand expansion and contraction due to temperature changes. Additionally, if the crack is large, you may need polyurethane foam to fill in the gaps.

Second, you’ll want some basic tools like a caulk gun and putty knife. You may also need an angle grinder or chisel if the crack is particularly wide or deep. Finally, make sure you have safety gear like goggles and gloves before getting started with any repairs.

Now that you’ve got all the supplies ready, it’s time to get prepping that crack for repair!

Preparing The Foundation Crack

It’s understandable to be apprehensive about preparing a foundation crack for repair; after all, the success of the entire project depends on it. However, with careful planning and attention to detail, you can have confidence that your DIY foundation crack repair will be successful.

When preparing a foundation crack for repair, start by inspecting the surface. If necessary, use a power washer or stiff brush to remove dirt and debris from the area so you get an accurate picture of what you’re dealing with. After that’s done, it’s time to do any additional cleaning or preparation such as chipping away loose mortar or using sandpaper to rough up the surface. Do not use too much pressure when cleaning though – if you damage the masonry, it’ll be harder to make repairs later on.

Now that you’ve got your foundation crack cleaned out and prepped for repair, it’s important to make sure that everything is dry before filling in any gaps or cracks with mortar. If there’s still moisture present in the area, let it dry out completely before moving forward – otherwise your repairs won’t hold up in the long run. And once everything is set and ready to go, you can fill in those cracks with mortar or grout and move onto the next step of repairing your foundation!

Filling The Foundation Crack

Once you have assessed the severity of the foundation crack and prepped the area for repair, it’s time to move on to filling the foundation crack. This is a crucial step in ensuring that your repair job is done correctly and securely. Here’s how to get it done:

  1. Choose a filler material – there are a range of options out there, including epoxies, polyurethanes, and hydraulic cements. Consider your budget as well as what will stand up best against water and temperature changes.
  2. Make sure your work area is clean – clear away any dust or debris before you start filling the crack.
  3. Prepare the filler material according to instructions – this might involve mixing two components together or adding water to dry powder.
  4. Fill the crack with the mixture – use a brush or trowel to press it into place, then smooth it out evenly with a wet sponge.

Now that you’ve got the foundation crack filled in, it’s time to seal it up! Sealing your repair job prevents moisture from seeping in and causing further damage down the line. To make sure your patch holds strong for years to come, follow these steps…

Sealing The Foundation Crack

Did you know that foundation cracks can cause up to 12% of a home’s structural damage? That’s why it’s important to recognize when to DIY and when to call a professional. Now that we’ve filled the crack, let’s move on to sealing it.

Sealing the crack is an important step in foundation repair, as it helps protect the inside of your home from water, insects and other elements. You can seal most small cracks yourself with epoxy or polyurethane caulk. If the crack is big enough, you may need to use hydraulic cement or a mortar mix.

When sealing a foundation crack, make sure you wear safety goggles, gloves and protective clothing. Work in a well-ventilated area, as some sealants contain strong odors and fumes. Carefully follow the instructions on the packaging for best results.

Now that we’ve sealed our foundation crack, it’s time to understand the limitations of DIY repair. A professional may be needed if any of these circumstances apply: if there is evidence of buckling walls or floors; if the cracks are wider than 1/4 inch; or if there are large areas of wetness around the foundation wall (which could indicate deeper problems).

Understanding The Limitations Of Diy Repair

DIYing foundation crack repairs can be a daunting task. But, if you’re up for the challenge, there are a few things to keep in mind before diving in. We’ll take a look at understanding the limitations of DIY repair and how to know when it’s time to leave it to the pros.

It’s important to understand that while DIY foundation crack repair is possible, it won’t always provide the same level of protection that professional repair can offer:

  • Professional repairs are often permanent and provide structural stability
  • DIY repairs may not fix the underlying issue – they might just mask the problem
  • Professional repairs are designed with expertise and knowledge of local building codes
  • Professional repairs can often last longer than DIY ones

So, when should you attempt a DIY repair? If your foundation has small cracks that don’t affect its structure or integrity, then giving it a go yourself may be an option. However, if your crack looks like it’s worsening or is affecting its structural stability, then you should call in professional help. It pays to have an expert opinion on any major repair job – particularly one as serious as this!

The bottom line is this: When dealing with foundation cracks, taking proper steps can save you from costly future issues. Make sure you understand the limitations of DIY repair and recognize when it’s time to bring in an expert for professional help.

Professional Foundation Crack Repair

When it comes to foundation crack repair, it can be a tricky business. That’s why many homeowners try to take the DIY approach first. However, sometimes professional help is needed.

Take for example my friend Joe who was convinced that he could fix his foundation cracks himself. He read a few articles and watched some YouTube videos and thought he had it all figured out. He even went as far as buying the necessary materials, but when he actually tried to do the work, he quickly realized that this was not something he could fix up on his own.

TIP: Foundation repair jobs can be complicated and messy so it’s best to consult an expert before attempting any repairs yourself.

It’s always better to be safe than sorry when it comes to structural damage in your home. If you try to tackle a job like this yourself and it goes wrong, you will end up having to call in an expert anyway – only after wasting time and money on failed attempts. Professional foundation crack repair services are available with experienced tradespeople who have access to the right tools for the job and know exactly what needs to be done. This can save you money in the long run by avoiding costly mistakes or worse – irreparable damage!

Cost Of Professional Foundation Crack Repair

The cost of professional foundation crack repair is no small matter. It’s a hefty price to pay for peace of mind, but it’s one worth considering if you’re not confident about taking on the task yourself. Repairs can range from a few hundred dollars for sealing up minor cracks to tens of thousands for more serious structural problems. Alliteration aside, it pays to shop around and compare prices from different contractors before deciding who to hire.

When hiring a contractor, make sure they have the necessary experience and qualifications – after all, this isn’t a job you want to get wrong! Ask your friends and family if they have any recommendations or do some research online.

TIP: Always ask questions! You should be comfortable with the answers before you commit to anything – that way you know exactly what you’re getting yourself into and can ensure quality workmanship. Your contractor should also provide a warranty on their work so that if there are any issues down the line, they can be taken care of quickly and easily. With the right contractor in place, you can rest easy knowing that your foundation crack is fixed up properly.

Foundation Crack Repair Warranties

When it comes to repairing foundation cracks, the old adage “better safe than sorry” holds true. As such, it’s worthwhile to research the warranties that come with foundation crack repair services. After all, you don’t want to be in a situation where you have to foot the bill for repairs again down the line. Here are four points to consider when looking into a warranty:

  1. Length of Coverage: How long will the warranty cover your repairs? You’ll want something that covers at least several years in case any issues arise.

  2. Types of Repairs Covered: What types of repairs does the warranty cover? Does it cover structural damage only, or does it also cover cosmetic repairs like painting and staining?

  3. Transferability: Can you transfer the warranty if you sell your house? Is there an option for transferring the coverage from one owner to another?

  4. Cost of Renewal: Does the warranty require any additional fees for renewal after its expiration date? Knowing what costs are associated with continuing coverage can help you plan ahead financially and determine whether a particular warranty is worth pursuing.

Knowing what kind of warranties are available can help ensure that you get the most out of your investment in foundation crack repair services. By researching these points ahead of time, you can prepare yourself for any potential problems that may arise and make sure your home remains structurally sound over time. Taking these steps now will save headaches down the road – not just when it comes to foundation crack repair, but also when it comes to maintenance tips for foundations cracks as well.

Maintenance Tips For Foundation Cracks

One example of a maintenance tip for foundation cracks is to check the area regularly. Every few months, take a look at the foundation cracks to make sure they haven’t gotten worse or opened up. If you spot any changes or new cracks, it may be time to call in some professional help.

When it comes to maintaining your foundation cracks, keeping an eye on them is key. It’s important to keep track of any changes and address them as soon as possible. That way, you can prevent further damage and costly repairs down the line. Don’t be afraid to get your hands dirty – patching small cracks yourself can save you money and time!

If the crack has become bigger than 1/4 inch wide or if there’s any sign of water seeping into your home through the crack, then it’s time to contact a structural engineer for assistance. Professional help is needed when dealing with more serious issues like these, as DIY approaches may not be enough to ensure a lasting fix for your foundation problem.

When To Contact A Structural Engineer

When you’re dealing with foundation cracks, it can be hard to know when is the right time to hire a professional and when you should try DIY repairs. It’s like a game of chess – one wrong move and you could end up paying more than necessary. As a handyman, I’ve seen enough foundation cracks to learn that there’s no one-size-fits-all solution.

To illustrate this point, think about it like playing a card game. You wouldn’t want to take out your ace until you were certain the other players had nothing higher in their hands. Similarly, when it comes to foundation cracks, you don’t want to invest in expensive structural repairs until you know they’re absolutely necessary.

So when should you contact a structural engineer? Here are four tell-tale signs: •\tIf the crack is wider than an eighth of an inch •\tIf the crack extends through both sides of the wall •\tIf water seeps into your basement after heavy rainfall •\tIf the crack is located near a corner or joint

Foundation damage can be costly if left unchecked, so if any of these signs apply to your situation, then it’s time for some expert help. Don’t wait around for problems to get worse; contact a structural engineer as soon as possible for an assessment and repair plan that fits your budget and needs.


Foundation crack repair can be a daunting prospect for many homeowners. But with a little knowledge and the right tools, you can tackle most repairs yourself. Just remember to keep an eye out for warning signs of structural damage, such as large cracks or uneven floors. If in doubt, it’s always best to err on the side of caution and contact a professional.

If you do decide to take on the project yourself, a successful foundation crack repair will require patience and attention to detail – but it can be done. Think of the satisfaction you’ll have when the job is done; it’s like that adage “If you want something done right, do it yourself” – only this time it’s literally true!

At the end of the day, foundation crack repair is one of those tasks where it pays to use your best judgment. DIY repairs are fine in some cases, while others may require professional help. Do your research and make sure to follow all safety precautions – then go forth and fix that foundation!
