"Couldn't be happier with the results, but the best part of the experience is all the amazing, hard-working, highly dedicated and profesisonal people who work for this company. We have an older home (1984 build) with a very large open, back patio. Water erosion and tree roots had wrecked havoc on the concrete causing joint erosion, extensibe wide cracks, shifting and lift. I didn't want to jack it all up and go to the expense of re-pouring and hoped this would be a smart solution. Joe, Kaly and Mark worked an absolute miracle and the results are exactly what I was hoping for. Their approach was thorough and meticulous and I knew from the get-go I was in good hands. I highly recommend you turn to them for all your concrete repair solutions and I won't hesitate to refer my clients to them in the future. You won't regret it!"

"I am very happy with the quality of work and product that I received. I have a decent sized lot and had 9 sprinkler zones installed last summer. Kevin and his crew did a great job. The communication was excellent as well. We had a pretty good rain on the first day and his crew did not come out due to it being too wet to dig. Kevin contacted me ahead of time to tell me they would reschedule for later in the week. They held to that promise. Kevin met with me after the install and showed me how to work the control box and make sure all of my questions were answered. I held off writing this review until spring of the following year. I was really concerned due to the really cold weather that we had during the winter that I would have issues with broken pipes. I tested all of the sprinklers in March and everything worked great. I definitely recommend this company to anyone needing a quality irrigation system installed."

"We used Vesta Foundations for our driveway repair. Mike, Omar, and Rudy did an incredible job and were very professional. They explained the different phrases as they completed each repair which was very helpful. They used a foam to fill in the voids underneath our driveway and also sealed our joints and put a drainage system from our gutters to carry the water on down the side of the driveway."

"Superior Excavations Solutions (Brendon) did an excellent job on my brother's anaerobic sewer system! My brother is a disabled veteran so I manage his affairs from New Mexico which can be challenging at times. But Brendon made it easy. He was working against severe rainy weather on a weekend to get this system in and get it up and running. My brother now has a new system and it is working like a charm.. I would highly recommend Brendon to put in any sewer system."

Oasis started in Tulsa in 2024, hauling and doing demo for local contractors — the kind of customers who drop you fast if you're late, sloppy, or slow. We weren't. They kept calling.\n\nNow we're University of Oklahoma students who've brought the business home to Norman — with crews, trucks, and trailers ready, and one of us running Oasis full-time. Licensed, insured, and building our name here the only way we know: show up on time, quote it straight, work harder than anybody, and leave every property cleaner than we found it.\n

"I recently bought a house and a few issues were pointed out by inspections. These guys were referred to me by friends and after getting a few bids, I had them fix my problems. They werent the cheapest, but they fixed my issues and that was all that really mattered to me.

Basement Waterproofing FAQs, answered by experts

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.
