"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."

"The consultation went great. Cary came out and spent about an hour measuring and evaluating our basement. He left me with a quote the same day as well as my options. Although a little pricey we decided to go for it. The guys came out a few weeks later to insulate and were here all day. No issues there. However, the basement has not warmed up since and we spent quite a bit of money and were told it would be about 60-65° down there. It only increased by maybe 5° and still isn’t even close to 60/65°. I emailed the guy Cary who came out and was told he’d talk to his guys about it. No response. I had to follow up. Then he said he’d send someone out. Never got a call or anything to schedule it. Again I had to reach out. Weeks later he finally said he’d come out on 3/18/21 at noon. It’s now almost 1pm and he’s still not here. Their service was great when they wanted our money but now that we have paid, it seems we are not longer a priority and they don’t care to come fix whatever the problem may be. Very disappointing. We spent thousands of dollars and our basement still feels very cold!"

"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!!"

"Budget Dry met my expectations in every way possible! (For the record, I am NOT in any way associated with the business or anyone who works there--this is a real testimonial). I was so pleased with their whole process, the price and the installation that I called their management to rave about how pleased I was. They installed a basement drainage system in an old leaky basement and a dirt floor crawl space encapsulation system where mold had grown. Our home was built in 1959. After several major rainstorms and four winter/spring months of time passing, all is perfectly dry and the obnoxious smell is gone!! The people on the job were skilled, considerate and did whatever it took to do it right. We were even visited by home office management and the salesperson during the job to be sure all was going well. I never take the time to write reviews, but Budget Dry deserves one from me--an extremely satisfied customer!! Folks, you can't go wrong by choosing them to fix your basement problems. Don't hesitate to call them and believe what they tell you needs to be done. They will be right all the way. Bill"

"We were dealing with a stressful basement leak every time it rained heavily, so we called Prime to waterproof our foundation wall. From the initial inspection to the final cleanup, they were professional, transparent, and incredibly thorough. The crew arrived on time, explained exactly how they were going to seal the foundation, and worked tirelessly to get the job done right. We just had our first major storm since the repair, and the basement is bone dry! If you want peace of mind and quality craftsmanship, I highly recommend Prime. They are worth every penny"

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.
