"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!"

"Francisco has to be the best service contractor of any trade. Very HONEST, responsive and great quality work. We had several other basement waterproof system contractors out, and all were clueless or gave inaccurate information. Francisco's knowledge and expertise was impressive. Now, after several months and heavy rains, the basement remains perfectly dry. We called Francisco back for some minor cosmetic sealing, and he responded perfectly again, on a weekend day. You won't regret calling Francisco"

"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

When hiring basement waterproofing pros in SC, prioritize those with proven experience handling the region’s clay-heavy soils and high groundwater. Look for specialists familiar with French drains, vapor barriers, and crawl space encapsulation. Choose contractors with strong local references, especially from neighborhoods like Five Forks, and ensure they offer comprehensive warranties and carry proper insurance for peace of mind during storm season.

Helpful?

Basement waterproofing in Simpsonville is designed to combat water intrusion caused by clay soils, frequent storms, and high humidity. It prevents mold growth, structural damage, and foundation shifting, while improving indoor air quality and energy efficiency. By managing groundwater and sealing vulnerable areas, waterproofing protects your home’s value and ensures a healthier, more comfortable living space throughout the year.

Helpful?

After basement waterproofing in Simpsonville, regularly test your sump pump—especially before the rainy spring season—and clear any debris from window wells. Clean gutters and downspouts every few months to handle heavy leaf fall from local trees. Use a hygrometer to keep basement humidity below 50%, and inspect for new cracks or efflorescence annually, as Simpsonville’s clay soil can shift and impact your drainage systems over time.

Helpful?

In Simpsonville, the time to complete basement waterproofing depends on the project’s complexity. Simple interior sealant jobs usually take 1–3 days, while exterior excavation or installing a perimeter drainage system may require 4–10 days, especially if weather delays occur. Crawl space encapsulation typically takes 2–4 days. Local clay soil conditions and permit processing can also influence the overall project timeline.

Helpful?

In Simpsonville, early warning signs include widening wall cracks, persistent musty odors, or water stains that appear after storms. White powdery residue (efflorescence) on walls, humidity consistently above 60%, or minor pooling water can signal underlying drainage issues. Watch for pests, warped baseboards, or increased HVAC use—these often indicate moisture problems that, if left unchecked, can escalate into major repairs.
