"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."

"They handled themselves in a professional manner. They explained the process of replacing the retaining wall and reinstalling the fence. They cleaned up the site and checked with us for any problems or concerns. I would highly recommend them to anyone looking for a contractor."

"Palmer Construction — Highly Recommend I called Brad at Palmer Construction about a roofing issue, and from the start he was thorough and professional. He came out to the house, took detailed notes, and gave me an extremely fair price. Once he and his crew got up on the roof, they discovered the damage wasn’t as extensive as originally thought, and instead of running up the bill, Brad was completely honest about it. He was transparent throughout the whole process, showed me everything, and walked me through exactly what needed to be done. Since then, he’s also handled several small projects around my house, and every time it’s the same story: reliable, detailed work done the right way. He really sets you up for success. I couldn’t be happier with Brad and his team, and I’d recommend Palmer Construction to anyone in need of quality, trustworthy work."

"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

Whether or not repairing your foundation is worth it before selling depends on the extent of the damage, the cost of the foundation repair, and your timeline for relocating. If the damage is major or structural in nature, chances are you’ll sell at a higher price if you take care of the problem beforehand. You should consider the cost of the repair first, though, as laying out thousands might not be possible with your budget. Additionally, if you’re in a rush to relocate, you might want to repair before selling so as not to limit your buyer pool.

You'll find a slurry of natural and synthetic polymers, rubbers, epoxies, and resins used to bond old concrete to new concrete. The right bonding agent depends on the method of concrete pouring you choose and whether you're adhering concrete over concrete or concrete over sand and gravel. Some concrete resurfacing mixtures contain bonding chemicals as well.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

Yes, you can replace a cinder block foundation. If a block foundation is too severely damaged to repair cracks and other issues, replacing the entire foundation is a viable option. The job will require a professional and can take between one to seven days on average to complete, depending on how complex the problem is.

It is possible for a slab leak to cause a sinkhole, but it would have to be a particularly serious leak. A slab leak causes the land under your home to erode and if there is enough movement depressions will form in the ground, potentially causing a sinkhole.
