"We hired them to build a retaining wall to level out our sloped backyard and install a new patio. They recommended natural bluestone bordered by classic bricks, and wow?what a difference! The stonework is flawless, perfectly level, and handles heavy rain with zero drainage issues. It looks like a high-end resort back here now. Worth every penny."

"This is a review of the *experience* we had with Quality. We had the basement waterproofed, so we won't really know how good the job is until a big rainstorm! So this is just the experience we had before and during the job. We reached out to Quality based on the Angie's List reviews, and were convinced by the visit from Greg. He was so knowledgeable about the water problems, and pointed out the years of experience the company has. Also, we weren't looking for a bargain, we were looking for a dry basement, and Greg was very straightforward about all the costs. Now we haven't had a rainstorm yet, so we still don't know the most important thing about the job! But Victor and his crew were fantastic. They knew what they were supposed to do when they got here, and did the whole job-- as quietly as possible-- in less than 4 hours. They were pleasant to have in the house. They left the place clean. So big thanks to all at Quality. P S: Will update when there's a big rainstorm."

"I have worked with Uprise twice now and both times they did great work. The first house they found and repaired a leak, and in the second house I had them install a new roof. I would not hesitate to call them again for future needs."

"Did a fantastic job fixing the foundation on one side of my house and installing a 10' outdoor sump pump. He also installed a 'rock garden' and french drain to improve drainage on the side of my house near a retaining wall- it not only works great but looks great too. Most importantly, Antonio was patient will all of my detailed questions, and he did a great job keeping me calm throughout the work. His staff was hard working, but also pleasant and respectful, and did a great job cleaning up when done with what was a messy job. Thank you!"

"Nelson the owner from Premier Basement came out and assessed my problem quickly. He is very professional, fair pricing, and walked me through a process that I knew nothing about with his vast knowledge and experience. I highly recommend him and his company. It was a great experience amongst so many who try to take advantage of you and price gouge with high pressure sales."

"The Situation:
We moved into a new home and discovered that the prior owner had created a makeshift water solution in the basement. We had been in the house for about 3 months and were getting increasingly anxious about this. The water was overflowing into the basement  and eventually running into the sump pit (which incidentally was sitting directly below our breaker box). The sump was exiting across the basement via a pvc pipe hung from the ceiling at an inverted angle. So a lot of the drainage water would backflow back into the pit , or just sit in the middle of the sagging pipe. 
Since we live on a high water table, this was the first major project I wanted to tackle. I researched and interviewed a few companies and after meeting with Bob (the salesman/engineer) we felt comfortable with American A-1s solution and timetable for the job. During the initial inspection we also discovered a bulge in our basement floor caused by hydrostatic pressure.

The Solution : 
French Drains running the perimeter of the basement and two new sump pits position away from the circuit breaker, but still at the lowest level. One of these pits houses 2 sump pumps. One positioned higher than the other in case the first one burns out. The second pit houses a water powered backup (http://www.basepump.com/Products/Basepump.html) positioned at a higher elevation than the standard pumps. This is in case of a power failure during a storm such as a hurricane. American A-1 recommended a different, less complicated water pump but after researching several online I decided on BasePump. I ended up having my own plumber install it , because of the comfort level I have with him. (RAM Plumbing)

The exit strategy was well though out. The exit is directly above the pits through our foundation wall. From there the PVC water pipe runs underground to a seepage pit underground in our front yard which pitches away from the house. While I would have preferred the water to run into the town storm sewers, there is an ordinance in Ridgewood that prevents this.

After the installation we were a bit concerned because the pumps were running every 5 minutes. However recently this has died down to about once ever 90 minutes. And I assume will decline further as the ground dries out from the winter melt. If not we may need to raise the level of our pumps a couple inches.

Lou the foreman of the job was amazing. He was EXTREMELY respectful of our property and concerns. This is not a trivial undertaking. You are essentially jack hammering cement from  your basement and having it removed. When you are buying these drains for the price of a down payment on a nice car, its great not to have to worry.

The only minor issue we ran into was with the electrical inspection. The American A-1 recommended electrician used switches that were not matched to my current breaker box. The inspector failed us for that. The electrician was back within a couple days to change them out and we passed with flying colors.

Anyway ... our basement has been dry since and with the exception of the pump frequency we have had ZERO problems.
Here are a couple pictures of the work ... the staining you see on the floor is just the new cements still not fully cured yet."

House Leveling questions, answered by experts

The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.

Mudjacking is suitable for sidewalks, driveways, patios, and nearly all exterior flat structures. However, it may not suit severely damaged or heavily cracked areas.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The total drying time can vary depending on the size of the project. Because the slurry mixture contains cement, it needs to harden fully to prevent the concrete slab from shifting under added weight. You should avoid walking on the concrete or placing heavy items like furniture or vehicles on the surface until it has fully set. Your concrete contractor can provide a precise timeline. As a point of comparison, if you opt for polyjacking, the polyurethane foam can dry in minutes, but it's recommended to wait about an hour before use.

Pros often use mudjacking or polyurethane foam injection to level a sunken concrete patio. Both methods lift the slab by filling voids beneath it. After properly compacting the soil beneath it to prevent future settling, the concrete may need to be removed and re-poured for severe sinking.

A good slump height really depends on the project, but there is a use for nearly all slump levels. For example, low slumps are best in projects that require structure, such as curbs and roads. High slumps often require additional reinforcement, but they flow more freely into hard-to-reach spaces.
