Have you been doing a slight home improvement here and there but noticed some unsightly cracks spreading across your foundation? If so, you’re probably asking yourself the same question many homeowners think: can I repair foundation cracks myself, or is it a better job left to professionals?
Foundation cracks can be distressing to see, but not all cracks require expensive repair. In this blog, we’ll explore when homeowners can take on a crack repair themselves and when it’s best to leave it to the professionals.
When are Foundation Cracks a Problem?
It’s important to first evaluate the severity of any cracks you notice. Minor, hairline cracks are quite common as a house shift over time. However, major cracks over 1/4 inch wide or those that are growing larger could indicate deeper issues. Another red flag is if cracks form a zig-zag pattern – this may mean the foundation is moving in multiple directions.
The location of cracks also matters. Those running vertically down walls are typically more worrying than horizontal ones along the top of a wall. Cracks near the corners of your home’s foundation or encircling your entire structure raise more concern as well. And obviously, any cracks associated with water leaks, drainage issues or sloping concrete should be attended to promptly.
Isolated small cracks may not require much intervention. But larger, unstable cracks—especially if combined with other signs like noticeably sloped floors—probably warrant professional review to ensure the foundation’s integrity.
DIY Foundation Crack Repairs
Let’s explore some DIY options and when it’s better to call in for help.
Basic Repair Methods
For minor, stable cracks less than 1/4 inch, homeowners can consider basic repair methods for minor, stable cracks less than 1/4 inch. Thoroughly clean out cracks using a wire brush to remove any loose material. Make sure the area is completely dry before proceeding.
Filler Materials
Next, choose crack repair materials carefully. Epoxy crack fillers and hydraulic cement formulas bond strongly and cure hard. Apply strictly according to package directions, filling the crack smoothly from bottom to top.
Tools to have
Common tools needed are a putty knife, trowel, wire brush and, of course, the repair product. Ensure adequate ventilation and read all safety precautions when using chemicals like epoxy. Once dry, paint or seal over the area for protection.
Proper preparation is key – thoroughly cleaning and drying cracks yields the strongest bond. Go slowly, monitor for full curing and be careful not to overfill. With care, basic crack repairs can work well for isolated narrow cracks. But as soon as issues like water come into play, it’s best to seek an expert.
When to Seek Professional Help
Certain situations are simply not feasible or safe for DIY work. Large or complex cracks that fork off in multiple directions may require specialized injection epoxies to fill fully. Vertical cracks spanning load-bearing walls could indicate deeper settling issues impacting structural integrity, too.
Other warning signs include cracks accompanied by sloping concrete, crumbling or disjointed blocks or walls, or water penetration. Groundwater issues demand professional-grade waterproofing systems. An experienced contractor can also evaluate if cracks are indicative of drainage or soil problems requiring excavation repairs.
Distress signs around the perimeter of a home, like misaligned doors or windows, are red flags. So, too, are cracks visible from both the inside and outside – implying a through-wall failure. When in doubt, call in an inspector – they can assess if crack patterns point to past or impending problems. An improperly repaired crack risks further damage down the road.
Professional Foundation Repair
Experts handle all types of crack repairs while protecting homeowners’ structural investments. Larger crack repairs involve chipping out failing material and selectively reinforcing. Epoxies may be injected under pressure deep into cracks to form a permanent seal from the inside out.
Contractors also check for underlying causes like settling, drainage inadequacies or grading issues. Their waterproofing expertise defends against future moisture penetration. Reputable companies provide multi-point inspections, detailed estimates and guarantees on workmanship.
In Calgary, for example, Alberta Parging offers over a decade of residential and commercial foundation services, including crack repairs, parging and structural solutions. They inspect structures, recommend appropriate remedies and expertly complete projects professionally yet affordably for clients.
Conclusion
In summary, repairing a few small, stable cracks around your home is certainly worth a do-it-yourself attempt. With careful preparation and execution, occasional cracks can be maintained independently. However, for complicated crack patterns tied to concrete structure failure or larger through-wall breaches, the risks outweigh the rewards.
Unless you possess specialty concrete skills, it’s safer and wiser to hire a licensed foundation contractor. Professional assessments prevent overlooking issues which, if left untreated, could jeopardize safety and financial investments in the long term.
So, weigh your options – minor cracks may DIY, but complex concerns always call for expert help. With smart choices, you can keep those foundation cracks at bay!
