"Northern basements was able to fit us in quickly, pulled our crooked cement wall back in-place and sealed the wall to prevent future leaks.  The work was timely, communication was friendly and detailed, and price was as to be expected for the large amount of work that needed to be done.  We are very pleased with the whole process as well as the results.

"Mac did an outstanding job replacing our poured concrete sidewalk. He was able to do the work quickly, on budget and the result was outstanding! Mac was great to work with...no problems communicating with him. We wanted to make sure our project was done with minimal impact to our yard and Mac did a great job in that regard. He also cleaned up after the work was done. I would recommend Sullivan Stone (Mac is the owner) without hesitation! We're planning another project for next year and I will definitely reach out to Sullivan Stone to assist us with that as well!"

"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."

"When I first called, I was surprised at how quickly they returned my phone call to set up an estimate. He was able to come over the next evening to check out our basement. He was punctual and provided us information about what would need to be done. He stated that he would provide us with an estimate that evening. I waited, but the estimate never came. I called the following week to see the status of the estimate. They stated that they were busy, but I should have it by now and would email it ASAP. After a second week, I called again. They said they would get it to me again. After the third week, I called again and was told the same thing. I gave up at that point and contacted someone else, who will be fixing the basement tomorrow. It's been over a month now and never received an estimate for the work. I understand that it's a busy time of year, but was disappointed to never get the estimate and didn't feel like I should have to pester them for it.

"TJL Construction remodeled our bathroom: took out old tub and vanity and installed new plumbing, shower, sink, light and other fixtures, ceiling, flooring, and painted. Matt Swan was great to work with. He provided a detailed estimate and stuck to it. Work was done on schedule, all materials were cleaned up and cleared away. I would highly recommend their work."

Foundation Repair questions, answered by experts

Cracked tiles can mean foundation problems. Fortunately, most of the time, cracked tiles happen as a result of accidental damage. It is important to determine the cause of cracking to rule out underlying foundation issues. If your tiles were not damaged due to dropped items, heavy loads, poor installation, or inferior tile quality, and the cracks are spreading throughout your flooring and not limited to just one area, you may be dealing with foundation problems. These can include drainage problems and even foundation failure, so it is vital to call a licensed contractor to assess the issue and ensure your foundation is safe.

Violating building codes can lead to a number of consequences, including fines, citations, and even being required to demolish the structure and start over. If your house isn’t compliant with code requirements, you can also run into trouble when it comes time to get homeowners insurance or sell your house. Following all applicable building codes will avert costly consequences.

Most single-story homes don't have foundations strong enough to support a second story, but they can be reinforced for an addition. A structural engineer can assess your foundation and what needs to be done to get it ready. They'll look at any cracks or unevenness in your current foundation and consider any special framing or beams your home needs, especially if it’s in a high-wind or hurricane area.

“To support a second story, many structural engineers will require that you install additional concrete piers in the crawlspace,” says Tschudi. “This involves hand excavating, pouring a large concrete footing—usually with specially coated rebar—and then building concrete piers right up to the girders.”

Yes, thicker concrete is less likely to crack. The thicker the concrete is, the less susceptible it is to extreme changes in weather conditions that often cause concrete to crack or chip. If you’re unable to install a thicker concrete driveway for any reason, you can also ask your professional to install more rebar or wire mesh to provide greater strength and better resilience to damage.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.
