"I hired Arnold Masonry to find and fix a water leak in my chimney that had somehow survived two previous masons / chimney repairs, re-flashing twice, and replacing the roof. The good: * He was the only mason (of this round) who even returned my call. * He was the first to suggest that he starts by finding the leak with a garden hose. * He found the leak on the first day, and identified that the problem was a crumbling chimney cap due to inferior construction. * He replaced the chimney cap, and the leak has stopped (even through two hurricanes). * Total time: 3 days of labor, totaling about $4500. The bad: No complaints about the masonry performed, but * The leak-finding method only works if he actually sprays water into the leak. I didn't mind-- The interior stains were so bad that I didn't mind making them worse and I was pretty desperate to fix the problem-- but it makes the damage worse before it makes it better. (And you need to sign a waiver for the damage.) * He wants to be paid cash, on a daily basis. However, he does not seem to like to make predictions about how much each day will cost, so you either need to have a lot of cash on hand or run out to the bank when he finished for the day."

"Honestly, I have never had such a positive experience with a contractor. they showed up on time, were friendly, polite, courteous, clean and efficient. In a single day they installed the entire system and left the place clean (within reason). This included jack hammering more than 30 feet of concrete floor and complete water ejection. Unbelievable. They will never be the cheap solution, but they are worth it!"

"The gentleman who came to my home were absolutely great! Explained everything and made sure I was happy with the work every step of the way. I was nervous in the beginning but my fear subsided after Robert Charlesworth, Marcelo largo, Isaiah belcher and Johnathon Lopez made for a great experience. The attention to detail and dust control, tapping off areas they felt I wouldn’t want getting dusty exceeded my expectations! Thank you for your hard work and kindness. Trucks looked awesome new as well as tools and equipment. Great job guys!!"

"Outstanding! John took our vision and brought it to life in a way that went beyond anything we could have imagined. What could have been a simple repair turned into a complete transformation. The stonework they created not only improved the look of our home but made it stand out in the neighborhood. People keep stopping in front of the house to admire it. The quality, craftsmanship, and attention to detail are second to none."

FAQs for concrete foundation repair projects in Newtown, CT

Visible cracks, water leaks, uneven floors, or walls that won’t line up are classic red flags. You might also notice sticking windows, doors that no longer latch, or exterior cracks crawling up brick or siding. Even a damp, musty basement can hint at trouble. If you spot any of these, call a foundation pro right away. Early inspections cost far less than waiting until the damage threatens your home’s stability.

Yes, foundation problems impact your home’s value. Buyers want proof that the foundation is stable, and a recent, professional repair can actually boost confidence in your home. You’ll need to disclose the work, but documentation showing the structure was properly stabilized, especially with piers in regions known for shifting soil, often reads as a plus, not a problem. Skipping repairs, on the other hand, can cut your sale price and shrink the pool of interested buyers. Taking care of the issue protects both value and peace of mind.

Foundations are engineered for exceptional longevity when constructed correctly and maintained diligently. Concrete slab foundations remain structurally sound for 200 years, while other foundation types deliver integrity between 75 and 100 years. Regular professional inspections and timely maintenance further secure a foundation’s lifespan and ensure your home stays safe over the long term.
