"Steve is a good listener and followed through with our agreed on plan. His workmanship is one of a craftsman: precise and elegant. Our project involved building on an old foundation which needed repair work and strengthening, which he did, before proceeding. The end result was just what we had hoped for. We are very glad that Steve and his son Adam took on this project which met all our expectations."

"I contacted Accurate Basement Repair after my basement decided to spring a leak this spring. If Iâ m going to be honest, itâ s happened before, but not to the extent that it did this year. Iâ ve held off calling anyone out of fear of how expensive basement repairs can be and I was expecting the worst. Accurate was recommended to me by my mother and by another friend of mine. I called to schedule an estimate and the woman I spoke with was great. A few days later, John came out to my house to inspect my basement. He walked around and looked at everything inside and out. John recommended to do a drain tile test because although I had water coming in thru some cracks in the wall, I was not getting any water in the sump crock. He explained the process to me so I knew exactly what to expect. If youâ re curious on how respectful Accurate will be to your property, John did not want to cut into the carpet in my basement, he wanted to roll it back so it wasnâ t damaged.... I cut the carpet myself. Afterwards he wouldâ ve tried to fix the carpet I cut if I hadnâ t told him not to bother. After the drain tile test was completed, John explained the results to me in such a way that I understood. While my basement may need corrective repairs in the future, John made several recommendations for outside work that he suggested that I try first. If those donâ t work, he said I should do the corrective interior work. It wouldâ ve been really easy for John and Accurate Basement Repair to sell me a completely new drain tile installation to correct the issues I was experiencing with my home and I would not have bat an eye at it. If youâ re looking for a repair company that is trustworthy and honest, you donâ t have to look any further than Accurate. If the exterior repairs donâ t do the trick at my house, I will not have anyone else but Accurate do the interior repairs."

"Rivera Concrete Paving's $8,500 bid became $11,000. Owner Magdiel Rivera adds charges after you're committed and doesn't follow through after payment. Cost increases: I mentioned roots upfront - he said equipment could handle it, then charged $450. Said grading unnecessary, then created false urgency claiming we HAD to grade before concrete. Later said could grade after. Added $1,800. Crew broke drainage pipes, charged me $250. Couldn't move AC condenser despite my asking during estimate. Payment tactics: Said pay "when satisfied." Then requested half early, then full payment before done. When I said work incomplete, he asked "Don't you trust me?" then broke promises. Broken promises: Walkway cured wrong, no follow-up. $1,800 grading included 3-month landscaping - no communication. Promised debris cleanup, later said not responsible. Damaged 4-month fence, couldn't repair properly, paid $300 after pressure. Dismisses costs at estimate, adds them later. Makes promises, then excuses."

Foundation Repair FAQs, answered by experts

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Common issues with concrete that may require professional repair or resurfacing include cracks, spalling, uneven surfaces, and weather damage.

Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage.

Although some concrete cracks are cosmetic, others can be more serious. Cracks wider than ⅛ inch or that extend through the slab are serious and can cause structural damage. If you notice these types of cracks in your concrete patio, contact a local contractor who installs concrete patios to inspect the damage and determine how to fix it.

If foundation problems are not fixed, they will likely worsen over time, leading to more complex and expensive repairs. Neglecting a damaged foundation can cause a range of issues, including:

  • Structural Damage: Minor problems like small cracks can escalate into major structural issues. This can damage the house above the foundation and, in severe cases, lead to foundation walls caving in or a total collapse.

  • Water Damage and Pests: Moisture and water intrusion can cause flooding, mold growth, and pest infestations.

  • Health and Safety Risks: Mold can lead to poor indoor air quality and other health risks, while structural instability poses a significant safety hazard.

  • Reduced Home Efficiency: A compromised foundation can negatively impact your home's energy efficiency.

To avoid these escalating problems and costs, it's best to hire a foundation repair company to address any issues as soon as you become aware of them. The earlier problems are discovered and fixed, the lower the repair cost will likely be.
