Floor and wall gaps in your Edmonton home are red flags for foundation problems. Ignoring these can escalate to serious structural issues. Temporary surface-level repairs don’t address the actual cause, often foundation shifting.

Groundworks provides a robust solution with foundation piers and crawl space supports. These can elevate a sinking foundation and bolster sagging floor joists, safeguarding your property long-term.

What Are Floor Gaps?

Gaps between walls and floors may occur when flooring separates from walls or baseboards. These gaps can widen over time due to issues with your foundation.

While floor and wall gaps may not seem significant initially, neglecting them could compromise your home’s structural integrity and pose a risk to your family’s safety.

Problem signs associated with floor and wall gaps include:

Causes of Floor and Wall Gaps

Spaces between your walls and floors occur for different reasons, including:

Foundation Shifting

Uneven foundation support primarily causes floor and wall gaps. Issues with the soil beneath your home may cause the foundation to settle or sink, resulting in significant voids.

Damaged Floor Joists

Crawl space floor joists weakened by wood rot, excessive span, and other wear and tear can result in sagging floors and widen existing gaps.

Fluctuating Soil

Clay soils expand or contract in response to excess moisture. Expansive soils can elevate your foundation, while contracting soils may lead to foundation sinking. Both scenarios can result in gaps in floors and walls.

Can You Repair Floor Gaps?

Yes, but temporary solutions such as wood filler or footing trim won’t offer sufficient protection against foundational damage. We recommend addressing the root cause of floor and wall gaps instead.

Groundworks fixes gaps between floors and walls using our custom-engineered, patented products. By tackling both the symptoms and the source of this issue, we can protect your home’s structural integrity and your family’s health.

Our pier options for elevating sinking foundations include:

  • Foundation Piers: Installing helical, push, or slab piers can close gaps by potentially elevating your sinking foundation and stabilizing any movement.

Floor Gap Repair FAQs

Any space between your floor and walls can be a problem. However, gaps that get bigger over time could compromise your home’s structural elements. We recommend contacting an expert like Groundworks for foundation repair in this scenario.

Wood filler, footing trim, and other DIY repairs might temporarily conceal gaps. However, they won’t address the underlying cause. Only professional foundation repair can prevent further damage to your home.

Foundation shifts, weakened floor joists, and soil fluctuations could be to blame. We can pinpoint the specific reason for your gaps during our free inspection.

Cory came to my house, thoroughly evaluated the situation, explained the options to me, and patiently answered all of my questions. He is amazing. There was a crack in my basement wall that needed to be repaired. Paul (I think) did a good and clean Job. The repair was scheduled and completed exactly as was described to me. Great team! I’d definitely recommend this company to others.

Excellent service. Sales was pleasant and quote was thorough enough to proceed. The crew that came out to excavate, and install the interior and exterior basement systems was absolutely top notch – their work was neat and tidy, they showed up on time, and worked hard. To top it off, they (and all the folks involved) have to be the most pleasant contractors I’ve ever dealt with – and this is house #5 for us over the years! Thank you, Basement Authority. Highly recommend.

Yesterday we had our sump pump service by Ben and was very pleased with the work. He was knowledgeable and took care in his work. He was very friendly and explained what he was going to do. Very good at his job and we’ll ask for him if we need any work done in the future.

Fantastic service from start to end. Professional sales call, follow up, and terrific work crew on site. Did an amazing job of raising and leveling my driveway. The crew took great pride and were even excited with the outcome. I HIGHLY recommend their work.
