FAQs for foundation repair projects in Rockville, 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

  • Waterproofing materials
