"Our church was build in 1920s so the scope of the project increased as the initial water damage was worst than anticipated. Waterproofone addressed those issues and, installed a french drain system, rerouted water spouts, and added an external drain behind the rear of the church. Our basement has been dry ever since and all previous water damage has been replaced or repaired."

"Basement Gurus arrived to discuss our basement water issue. Dan patiently went over everything and listened to our concerns and answered our questions. He prepared a proposal to remove 4' of our patio and dig down to the foundation to waterproof the wall and fill the cracks from outside. He also suggested burying a downspout and pipe leading water away from the house and sealing the wall cracks on the inside basement wall. The team arrived as scheduled and worked incredibly hard for several hours a day. They were impressive in the system they followed and how much work they performed each day and were respectful of us and our property. By the end of the job everything was back in place. We wish the expense wasn't necessary, but felt the price was worth it due to the difficulty, the amount, and the quality of the work. We highly recommend Basement Gurus!!"

"I was having some issues with water coming into the basement through the foundation and walls during rainy weather. Not flooding, or even shop vac-able volumes, just enough to be annoying and require mopping. Dominic and his crew were here today to install an under-floor drainage system and a new sump pump. I was dreading the demo (I have a concrete floor) and the mess involved, but these guys came prepared for everything! They used dust abatement measures to protect all my basement-stored items, and they removed and hauled all the debris away when finished with the excavation. What really impressed me was the concrete restoration upon completion. I've previously had a sewer line replaced through the basement floor, and the contractor really "botched" the floor repair. I can't describe how different this experience was! The concrete installed today is immaculate! Dominic takes pride in his work and with good reason! The new concrete is perfect! I am thrilled!"

"Excellent job repairing a crack in our poured concrete basement wall. Had to dig down to the bottom of the foundation, seal the crack, and back fill the hole - clean up was so good you didn't know work was even done. Very satisfied with the initial estimator, the job foreman, and the crew. The price was competitive with other estimates we received. Would recommend this company."

"Led by Brett Boyles (foreman) out of the York/Red Lion area; Brett, Clarence and John took care of some flooding issues that have been plaguing us for years. They fixed cracked cinder block walls, they put in a BDry system that is BEAUTIFUL, they turned a passive French-Drain system into an active system, and they turned an unhealthy basement into one with healthy air quality. They worked so hard and were so courteous, I feel so much more relaxed now. Brett knows his stuff and the other guys were awesome as well. I am so grateful...NOBODY ELSE will touch my basement ever again.....only 58 Foundations!!! Thank you guys, very much. Sincerely, Dan Crum"

Foundation Repair FAQs, answered by experts

Generally, foundation cracks and repair are not covered by standard homeowners insurance policies. This type of damage is often considered normal wear and tear or a result of poor maintenance, which is the homeowner's responsibility. For example, damage caused by settling, shifting soil, or drainage issues is typically excluded.

However, there are exceptions. Coverage may apply if the foundation damage is a direct result of a covered peril, such as a house fire, a burst pipe, vandalism, or a vehicle accident. Coverage for natural disasters like earthquakes and floods often requires a separate, specific policy or add-on.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

Concrete can crack from general wear, improper installation, or in response to uneven support from the soil underneath. Small, thin cracks on the surface of aging concrete are usually a result of normal wear and tear, while cracks on new concrete more likely indicate a problem with installation. Larger cracks or uneven steps can signify a much more severe issue. A concrete contractor should be able to diagnose the cause and repair concrete cracks for you.

Crumbling concrete steps will affect your ability to drill into the material and affix a sturdy railing. If the damage is primarily cosmetic, you might be able to DIY the repair with a patch kit. If the concrete is badly crumbling, hire a professional who specializes in pouring concrete. The average concrete step repair cost is $500 from a professional, but the extent of the damage will determine your actual cost. The professional may recommend a replacement if the damage is extensive.

The best foundation repair method will depend on the issue you’re having, but usually, foundation instability is best fixed using supportive piers, like steel piers or helical piers. A professional foundation repair contractor or structural engineer should always decide what the best course of action is, and even then, it’s imperative that you also take measures to treat the underlying issue as well, like soil erosion or oversaturation from runoff.
