"We were getting some water in our basement, which The Real Seal determined was coming from a crack in the foundation. They identified and repaired the crack quickly. Our technician worked neatly and efficiently, and all staff were pleasant and responsive throughout the process."

"Perfecto and his team came to fix the cracks in the foundation and reinforce the foundation wall. The team was efficient. An exterior trench was dug, rods were drilled through the foundation wall and through 12 feet of dirt and secured deep in the trench as well as in the basement. This process was repeated every 4 feet across the width of the wall. The cracks were repaired both within the foundation and on the basement wall. The fact that they were able to do this major amount of work in a two day turnaround is amazing. They backfilled the trench and relined the basement walls. This team clearly knows what they’re doing and they do it well. I would highly recommend Perma Seal to anyone experiencing water problems. I used them 20 years ago to install drain tiles and a sump pump. I am happy to see they still work with high standards and integrity."

"It was through my town home association is why there wasn't a charge to me. As indicated their work was very good. Overall rating of a C is because of the time frame. Almost 5 weeks between initial contact to the repair."

"The worker who came over saw my situation and unoffically suggested a repair that would be cheap for me rather than have him and his crew come out and charge me a few thousand. I appreciated that he wanted what was best for me and not necessarily best for his company."

Foundation Repair FAQs, answered by experts

If your foundation is unfinished, has surface damage, or is just plain unappealing, foundation refacing can be another great way to increase your curb appeal and give your foundation a fresh look. Used in conjunction with foundation planting, refacing can completely change the look of your foundation and your home. 

A slab-on-grade or slab foundation is a great option in many areas—usually in warm or moderate climates—and has been a successful foundation style for many decades. Slab foundations don’t require excavation or concrete block wall construction, so they’re the least expensive foundation type. They’re also the fastest to construct and don’t have many issues with moisture or water intrusion. However, they don’t give you extra storage space or potential living space like a crawl space or basement would, and they’re not ideal in colder areas where utility lines can freeze and frost heave can cause major damage.

Visible cracks, scaling, flaking, and uneven surfaces indicate a bad concrete job. Additional signs vary depending on the project. You may notice poor drainage or even exposed rebar. Quality issues result from using the wrong concrete, rushing the work, or inexperienced workers completing the job.

Trenchless sewer replacements are actually a great solution for sewer lines located under concrete. A professional can still sleeve and burst old piping to make room for a new one without having to dig up your slab.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.
