    "Bobby and the Fortress Techs were very professional, considerate, and thorough. The difference we feel from the crawl space insulation from before to after is amazing. Within just a day or two that musty smell in the house that was coming from the crawl space was gone! Bobby kept us informed throughout the entire process and finished the project on time. I would highly recommend Fortress Foundations Solutions to everyone; we were extremely satisfied with the outcome and the high quality customer service we received."

    "I just wanted to take the time to say thank Aquaguard for the many years of professional, responsible service and also for your recent service at my home. I have had both sides of my basement waterproofed, sump pumps replaced, and then also had them secure a foundation leak in the basement wall. All was done professionally, timely and courteously. Most importantly, Aquaguard has always promptly supported their guarantee and followed up with any problems that occurred over the years. I have referred this company to many friends and family members who also have been very pleased with the quality and professionalism of their company. There have been many friendly, courteous technicians who performed the work at my house but I wanted to give a shout out to Jason, who goes above and beyond amazing customer service. When he arrived many weeks ago to check on a foundation question that we had, he assured me that it was not a major problem but that he would return to fix the cosmetic work. I had forgotten about this issue because of the holidays but was pleasantly surprised when Aquaguard followed up with a phone call to schedule an appointment for Jason to come out to perform the work. Again, he called, arrived promptly and did a wonderful job completing the work. Thank you for your years of service and especially for the peace of mind with waterproofing at my home."

    "It is with deep satisfaction that I recommend Gradys Painting and Plastering & Construction. Mr. George Grady is a skilled craftsman. He was hired to correct long neglected and extensive masonry and window issues on a large, beautiful Presbyterian Church built in the Civil War era in Philadelphia. The property was neglected with only minimal maintenance performed over the last 40+ years. The building was in severe decline and in need of stabilization and restoration on many fronts. Cracked ledge plates were chipped out and reestablished, internal walls damaged by leakage were broken out and repaired, brickwork was repointed and in severe cases reestablished to original strength and beauty. Leaks around the base of the building were addressed to stabilize deterioration of the foundation. Large rotted window sills under beautiful stained glass windows were restored after significant masonry reestablishment due to water damage under the rotted out sills. Broken and missing stained glass windows are in the process of repair and replacement. The process started with new metal frames cast by Mr. Grady. The new frames will hold clear painted replications of the original stained glass, also crafted by Mr. Grady. Regular windows all around the church and manse were also repaired and restored. Roof leaks were accurately identified and repaired. A sagging plaster ceiling has been torn out and restored. All this work was done by Mr. Grady alone or with an occasional helper. He worked with care, expertise and respect for the original structure. The results far exceeded our expectations and have injected new life into a building on the brink. This building, owned by the Presbytery of Philadelphia, now houses a new urban ministry in a newly gentrifying area of the city. We are happy to have had the good fortune to be connected to Gradys Painting and Plastering & Construction by Service Magic."

Modern basements tend to serve as a recreational area for families since they can be finished to hide equipment like the furnace or water heater. For many people, though, the basement is the place where their home’s plumbing, HVAC, and sewage systems collide into an elaborate system of pipes and devices. Because the basement is out of the way of the rest of the residence, many homeowners won’t realize there is a leak until they are knee-deep in water.

A leak needs to be fixed as soon as possible after discovery since the water can cause mold, mildew, and damage to furniture and possessions. Some common sources of basement leaks include:

  • A crack in the wall
  • Damaged mortar
  • A cracked or broken pipe
  • A faulty water heater
  • A failing sump pump

When a leak happens, call a professional. Enter your zip code and HomeAdvisor will locate basement leak repair services near you.

    Desired Completion Date: Timing is flexible
    Request Stage: Planning & Budgeting
    Problems: Excessive dampness
    Problems: Basement flooding
    Comment: Starting in February after we’d gotten some heavy rain, water began to seep under the wall in our basement that we share with our neighbor. (We are in a townhouse.) The water would seep through, we would sop it up with a couple of bath towels, it seeped through again, we would soak up the water, etc.. This only lasted two days off and on and then we didn’t have any problems until about a week ago. Every day for a week we have been sopping up water, even though it hasn’t rained heavily for days. The rain may be coincidental. Our backyard is dry. It could very well be a leaking pipe in the wall. There is an AC drain pipe in that wall. Our AC has been running, as it has been very warm, and we had it running back in February when it was unseasonably warm.
