"I waited a few months before posting my review to test the finished product. All I can say is incredible from start to finish to performance! Jordan and Jim are two of the most honest people I have ever met. The estimate process went so smoothly. No pressure, no overselling and scare tactics I had with other large companies. Jordan listened and offered real solutions. In fact they turned out to be over $15K less than the next bidder. Jim who also owns the company and his crew showed up on time. Worked their butts off and explained exactly what and why they were doing certain things.Just another level of transparency. They put in french drains, concrete walls to support the compromised brick ones in the basement. Then two new sump pumps one is a no power required backup, a pump to remove the washing machine water into the sewer line instead of the sump pump. The also wrapped the basement, crawlspace, installed a new crawlspace door. All in two days! The house is so much nicer and dryer. My AC does not run as often, the basement is dry. We used to get water after every rain storm. We have had several heavy downpours and not one single drop of water! I highly recommend them. Fair and honest people!"

"They leveled our sagging floors beautifully and installed a drain system with a sump pump to address basement flooding issues. All was done with punctuality, precision, and professionalism. Additionally, the price was very reasonable especially compared to competitors. Highly recommend."

"I've worked with Donnie on several properties to evaluate structural issues, he's always been very professional and thorough with his inspections and identification of structural issues. Recently I had him perform a structural repair on one of my properties that had a tight deadline due to insurance and he got it done without an issue. I would recommend Donnie and Upstate Structural Repair for any structural repairs or consultation!"

"Overall very good - came out quickly, completed repair the same day and also let me know about some additional issues they found that I was able to fix myself. The price seemed a little high but I don't have a lot to compare it to. I was just glad to get it fixed so quickly."

"Such a great experience! Had another bid from a local company and was jerked around for months. Spaulding Decon got right on the job In my house within a week of my contact and work done within 6 days! My bathroom had terrible black mold all over the ceiling and down the walls. Same in hall . Chris was my contact guy. I wanted more stuff done in the middle of the work. He was so accommodating; and the upgrades were very well priced. Chris, Nick, and cianen were also lovely and tolerant of my special needs dogs, who were in the way a lot. Hire these folks. They WILL meet your expectations!"

Basement Waterproofing questions, answered by experts

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.
