I pride myself on my professionalism, as well as my ability to complete every job to the homeowner's total satisfaction. I never leave a job unfinished, or a homeowner not 100% satisfied with my level of service - Call today!

"Sealtech waterproofing services goes beyond what one can expect! Dani, the owner explains exactly what he will be doing and what he says he will do actually happened and then some! Unlike some companies, you are told one thing then another happens or does not happen! First off, Dani has to be satisfied with his work before he will leave it. He said and proved many times, "I want it done right." This attitude gave us a sense of trust that our work would done correctly and completely in a timely and prideful matter. The job for us was to stop the flow of water from a ditch beside our house which was spilling water over into a swell each time it rained. Dani did a wonderful job of putting in drains, boxes, river rocks and grading our property. He kept us informed each step of the process and we knew what he would be able to do and what we should expect from his work. Since the completion of the job he has come back by just to check to see if we have any questions and that everything is going well. You will not find a better company that Sealtech Waterproofing for your drainage and landscaping needs!"

"After researching about a dozen foundation repair companies and narrowing my selection down to two…We selected Foundation Doctor over a national firm. So glad we did.

DryWorx LLC is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers interests, and make their concerns the basis of our business.

"I hired DRYWORX to waterproof my basement. The founder, Jason Lott, took my deposit but did not start work until 2 months later. Once started work, took another month to finish the work at my house. But less than 2 weeks after paying him in full, the ground started eroding away from the house because he did not compact the ground, so the work was not done! We called him and he did not come to see the problem until almost a month later. After assessing the problem it took him over 2 weeks to come fix the problem. When he showed up to fix the problem, he did not come prepared with the right tools or materials. Not only did he not fix the problem, he was deceptive and tried to covered up the problem with dirt. Upon an inspection with him, it was uncovered that he tried to cover up the problem with dirt, his worker started getting violent and Jason threatened that "you don't want to mess with him". They both left the house and did not return to fix the problem and left my property in worse condition than when they arrived. I paid him in full but now I have to hire contractors to finish the work that he failed to do."

Basement Leak Repair questions, answered by experts

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

There are several reasons why you may find water dripping through your ceiling. This leak could be the result of a plumbing issue or a damaged roof. It’s important to determine the source of the leak before it causes damage to your home and belongings. Taking steps to catch the water immediately will help with additional issues.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Although waterproofing your basement may not directly increase the value of your home, it will protect the value you already have by preventing water damage. A basement without any signs of water will be more appealing to prospective home buyers. A leaky basement is a major red flag during a home inspection, and it will likely reduce the amount that buyers are willing to pay.

Heavy rain can affect a leach field because the extra rain can cause the groundwater level to rise. This leads the soil around the leach field to become saturated with rainwater, so it’s no longer able to take in effluent from the leach lines for final treatment. Heavy rainfall can cause the leach field to flood.
