"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"Rick responded immediately to my e-mail inquiry through the website and called me to set up an appointment.  He was extremely professional, courteous and knowledgeable.  As it turns out, after making the arrangements for the sump pump, we discovered the source of our water was from our heating system.  When we informed Rick of this and the fact the sump pump would not be needed, he promptly refunded our deposit.  I would definitely recommend Rick Jackson and will contact him in the future if the need arises.

"Our house's cinder block foundation is leaky in key spots and the recent monsoons meant some water got inside the house. Sean came out to inspect and quote. The plan was to remove a French drain to dig a trench, waterproof the foundation, and then put the French drain back. The price was reasonable plus he guarantees his work so that made us feel comfortable. His crew led by Hector, started work a week later by moving the French drain and digging a 5-6' deep trench around the offending area. They stuccoed and then waterproofed the foundation. When a couple of issues came up (as they always seem to in-house repair), Sean came over, assessed, and explained the situation and we agreed on the best way to proceed... and they carried on without missing a beat. Post-job care was good too as a few days after they were done, we had an issue with settling which caused the drain pipe to disconnect from the French drain. Sean and Hector came out to take a look and they put it right that day."

"excellent, they arrived on time, did an excellent job, answered all questions to our satisfaction and didn't even mind us watching the work if we wanted to. They left the place as clean if not cleaner than when they arrived. would definitely hire them again, AND they were the low bid of all proposals received."

"When I first met Stavros, he discovered damage that another company completely missed. His inspection was thorough and he explained the situation so we could easily understand what was happening and what we needed to do to repair it. He and his crew then did a very thorough job repairing our concrete foundation that had cracked and was sinking due to problems with the subsoil, as well as leveling the concrete slab in our basement. He took care not to damage our property, and even maneuvered his equipment under our deck so we didn't have to remove it to complete the repair. He and Athena genuinely care about their customers, and were empathetic and kind throughout what was a difficult experience for us as homeowners. I would not hesitate to recommend Arta to anyone who needs foundation work."

FAQs for concrete foundation raise projects in Portsmouth, NH

On average, it takes two to seven days to physically raise your house. However, this does not include the preparation work, which is often the most lengthy process. The entire project, including preparation, obtaining permits, disconnecting utilities, and any subsequent landscaping, can take four to eight weeks. This timeline ensures everything is done safely and that your home remains structurally sound.

If proper safety protocols are not followed, raising a house can cause severe damage, as the process involves applying controlled force to the home's structure. The risks involved make it crucial to hire a skilled contractor who uses engineered methods to secure your home and prevent any harm to your household.

If your foundation shows signs of instability after raising your home, you might need to add structural support. A structural engineer can assess your foundation and recommend reinforcements to ensure your house stays stable and safe for the long term. Available support options include installing additional piers or pilings, reinforcing existing footings, or using steel beams to distribute the load more evenly.

You will need a structural engineer to assess your home before you begin. These professionals determine whether your house is suitable for lifting and identify any issues that could compromise its stability. Their expertise ensures that the project is designed correctly and all risks are managed to achieve a successful lift.
