Foundation Repair, Crawl Space Repair, Basement Waterproofing, Crawl Space Encapsulation, Sump Pump, IntelliJack Crawl Space Support, Helical Piers, BasementGutter Drain, Crawl Space Mold, Crawl Space Humidity, Musty Smell in Basement, Cracked Concrete, Uneven or Bouncy Floors
"JES left my home in worse shape and won’t return my calls to come repair the damage left. I reached out to them to install a joist support system under my kitchen so that I can renovate this year. There were floor joists under the back door that had been cut during a renovation about 30 years ago. JES installed a jack system but then left my foundation under the door where you can literally see daylight from the basement. I brought this up to the crew before they left late Friday night (they worked long hours just to “finish” without even asking me if it was okay to trap me at home that late), and the lead just shrugged at me. Shortly after they left, it rained, and sure enough, water poured into my electrical room and all over the freshly poured concrete. I called Friday night, sent an email and text with videos, and called today 3 times. Each time the “production manager” is “busy.” Before this, they were perfectly capable of blowing up my phone to see if I could schedule sooner. JES is seriously lacking in work planning and professionalism."

FAQs for foundation repair projects in Knoxville, MD
If foundation problems are not fixed, not only do repairs eventually become very costly, but it can lead to structural damage to the house above. Eventually, if the foundation problems are allowed to persist, the foundation walls can cave in or collapse. That’s after other issues like flooding and mold have likely been allowed to develop. Although not all cracks are structural problems, some can be and even if they start out small, they can develop into major problems. The earlier foundation problems are discovered and fixed, the lower the cost to repair will likely be.
Yes, foundation repairs are worth the cost at any stage to avoid a dangerous living condition. A failed foundation can lower the value of your home by up to 20%. Whether it’s the smallest problem like a thin crack less than ⅛-inch wide, a horizontal crack, a crack letting water flow through, or a wall bowing inward, repairing foundation problems as soon as possible is worth the cost. Sometimes a temporary fix can be applied until you have the budget to completely fix the problem, but the longer the problems persist, the more costly repairs may be.
The most common first signs of foundation issues include:
Cracks in the foundation walls that grow
Signs of moisture or water leaking through cracks in the foundation
Standing water in the basement
Sagging floors or walls
Cracked walls in upper floors
Doors and windows that don’t close properly anymore
Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.
If you’re noticing signs of foundation issues, the first step to fixing a foundation problem is to hire a foundation repair inspector. They will determine the problem, the cause, and the severity before recommending a course of action to repair the foundation. The method for fixing foundation problems depends on the problem and what options are available. A few possible solutions include:
Epoxy injections
Mudjacking
Piers made of steel or concrete
Jacks
Hydraulic piers
Carbon or steel reinforcement strips
