"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."

"I cannot speak highly enough of Tom and Brad Green of Colonial Restorations. We have lived in our antique house for 16 years now, and like most old homes, some of its previous repairs were good, some not so good. Tom Green worked on this house for its previous owners, and his work was, by far, the best in the house. So, we continued to use Colonial - Tom, then Tom and Brad - as we learned the ropes about caring for an old house - our first house, old or new. Over the years, they have replaced sills and posts and beams, and rebuilt parts of our loose stone foundation. Most recently, they replaced the last original posts in our basement, (one of which was a tree trunk still with bark on it), including pouring new custom footings, in advance of our finally cementing the dirt floor. The work here is never easy - nothing is level, nothing is square - but the Greens' end result has always been beautiful - strong and made to last. Their prices are fair and without hidden costs....maybe not the lowest bid you might get, but you know it's a real bid that they will stand behind. They triage projects for us, giving us an idea of what other items will likely need attention in the next few years. We're not done with this house yet....we've never won the lottery, and there's always another repair..... and plan to use them again soon. I feel confident knowing that the next owners of this house, whoever they might be, will see the quality of the work and know that we cared enough to have the right people help us with the ongoing repair and maintenance of a 275+ year old house. I am a real person, a real customer, with no ties to the company, and was more than happy to write this review."

"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."

Concrete Repair FAQs, answered by experts

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.

A slab-on-grade or slab foundation is a great option in many areas—usually in warm or moderate climates—and has been a successful foundation style for many decades. Slab foundations don’t require excavation or concrete block wall construction, so they’re the least expensive foundation type. They’re also the fastest to construct and don’t have many issues with moisture or water intrusion. However, they don’t give you extra storage space or potential living space like a crawl space or basement would, and they’re not ideal in colder areas where utility lines can freeze and frost heave can cause major damage.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

Mudjacking is usually reserved for light-duty slabs, like patios, driveways, and sidewalks. However, it can be an effective way to lift garage slabs and concrete around the perimeter of the home, which could harm your foundation if it’s not done properly. The risk of damage is why having a professional mudjacking company carry out the work is important. This type of slab or foundation repair is relatively inexpensive, especially if you consider that a DIY job requires that you pay to rent the necessary equipment.

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.
