"Eric and his crew are knowledgeable, prompt, courteous, reliable, and hard-working. Eric listened to my requests, offered helpful guidance, and did a great job. He excavated a trench through a difficult, rocky area; installed electrical conduit; and removed a section of concrete pad for a renovation project. Highly recommend!"

"Paul Swann evaluated our foundation problem and referred us to an engineer who provided a detailed repair plan. Unfortunately, the nature and scope of the proposed repair plan was outside the parameters of what Northern Basement System's themselves could provide. We appreciated their honesty and have been looking for a contractor to take on the project."

"The work itself, the actual basement waterproofing appears to be working but our flood season hasn't come yet so, I'm reserving judgement. But, the way the work was done was a problem and the initial way that they got with the problem wasn't satisfactory. Eventually, months after work I did get some resolution but is wasn't a smooth transaction. We moved some of the finished portions of the basement to do their work and the way that that was handled was very sloppy and rushed, and very expensive to repair. And then, when the initial point of having somebody come and look at all my questions, it was not the owner, it was his foreman and it was not dealt within a professional manner. After 2 contacts, tried to explain what the problems were and has offered that they have an annual service to make sure that everything is working and there's a fee for that, though he offered 2 years of that with no cost, so that was a nice gesture. He tried to make up for the problems but like I said, there were problems."

"Colonial Restorations was superb.   Our family very much enjoyed working with Brad Green and Tom Green.  

At the outset, they made thorough assessments of our family's barn, identifying several problem areas and offering multiple proposals for how best to address each (including strategies and estimates).  They walked through the different proposals with us, addressing all questions and discussing different options.  This was extremely constructive and important to the process. 

They demonstrated very clear understanding of post-and-beam wood construction.  They displayed great expertise in working with wood (white oak, red oak, hemlock) and with the tools, jacks and cribbing needed for this work.  They worked carefully, always putting in place the necessary jacks and cribbing in advance of each phase of this project.

They were clear about their schedule and were very responsible about communicating with us.  If there were a day that they would not be on site, they let us know ahead of time.  With the exception of a snow storm and an illness, they were on site five days a week from the first week in January till the second week in February, 2016.  

By the completion of this project, Colonial Restorations had made significant and important structural repairs to our barn.  This work was done with care, craft, accuracy, and to code.  (All elements of this project were examined and passed by the building inspector.)  Most important, these repairs respected and worked with the existing structure and materials of the barn.

We could not be happier with these repairs or with the work done by Colonial Restorations.  It was a pleasure working with Brad and Tom."

Concrete Repair FAQs, answered by experts

Most building departments will require that a certified and licensed foundation repair professional or a structural engineer pull permits for foundation repair, so homeowners usually cannot pull them themselves. This helps ensure that an experienced professional completes all structural work on your home. Minor repairs that are technically DIYable often won’t require permits, but it’s still a good idea to hire a professional to carry out foundation repairs.

Minor slab leaks normally take around three hours to access and fix, provided the leak is in an accessible location. However, a more extensive leak or a leak in a hard-to-reach location can take several days to fix, depending on the resulting damage. You might also want to consider the timeline for the build-back if the leak damages building materials like flooring or cabinets, which can take several weeks, including delivery of the materials.

Tree roots don’t necessarily break through concrete on their own, but they can certainly take advantage of existing cracks, even very small ones. As roots grow, they expand the cracks, making them larger and leading to serious and costly foundation damage. It’s a good idea to have repairs on any foundation cracks you’re concerned about.

The best foundation repair method will depend on the issue you’re having, but usually, foundation instability is best fixed using supportive piers, like steel piers or helical piers. A professional foundation repair contractor or structural engineer should always decide what the best course of action is, and even then, it’s imperative that you also take measures to treat the underlying issue as well, like soil erosion or oversaturation from runoff.

Foundation repair costs $250 for a minor crack that doesn’t affect the structure’s integrity, although it can cost as much as $800 if it’s a major crack. Call a pro to get it fixed as soon as possible if your crack is bigger than 1/8 inch wide. Additionally, if you need to seal the foundation to fix leaks, it can cost approximately $2,000 to $7,000.
