"The workers were skilled and efficient. They did a great job. My project was small, but difficult and they did it very well. I was very concerned that someone would fall and get hurt because the sidewalks were not level. That concern is gone. The price was reasonable, and well worth the money spent to get this work done. I highly recommend this company."

"Thrasher did an excellent job repairing our driveway. They leveled out the entire driveway with amazing precision, and they fixed all the gaps with an attractive sealant that blends beautifully with the concrete. All of the team members I interacted with were professional and polite. I am very pleased with the results and only wish I’d called them sooner."

"Installed 7 push piers in two days and was able to raise the foundation of one wall up one inch to level it back with the rest of the house. The crew of Jonathan H, Manuel A and Gerardo T did an efficient and clean job. I was kept informed at every step of the process."

"Very competent, honest, and knowledgeable in all areas of construction and codes - predicted issues before they came up. Came well prepared. It cost me more than I had hoped because I had not realized the change in support structure required or the complexity of the existing structure. It was still considerably cheaper than other bids and his bid was very detailed. Very good work and exhibited great care in not damaging anything else. Best carpenter I have used in Colorado and probably the best I have talked to. I would use him for anything he thinks he could handle. I trust him and his work."

Customers say: Terrific value

"Francisco Garcia did an excellent job finishing our basement. The work quality is excellent. The communication and flexibility throughout the project was excellent. The project finished on time within budget with zero surprises. Any concerns that arose were addressed expeditiously and professionally. I highly recommend Colorado Paradise Builders for your next project. The building inspections were coordinated by Colorado Paradise Builders and passed easily. We learned while talking to the inspectors that we had a gift by using Francisco as a general contractor. They mentioned other people in the business may not provide the level of customer service and professionalism which Colorado Paradise Builders demonstrated on our basement finishing project. I could not be more enthusiastic with a recommendation."

House Leveling FAQs, answered by experts

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

The method involves lifting settled concrete using pressurized cement slurry via drilled holes. This solves uneven surfaces and prevents further settling.

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.

Many contractors offer warranties for their work. Confirm terms before starting the project.

Concrete leveling is absolutely worth it if you have sunken concrete slabs and want to restore them to level, especially if the slab is part of your home foundation. Concrete leveling is less than half the price of replacing concrete sidewalks, patios, walkways, and pool decks, and it’s about a quarter of the cost of replacing a foundation. If you also treat the underlying problem, it can be a worthwhile and permanent solution.
