"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.

"Peter came to my house and I told him the items I wanted him to fix.  He made recommendations, said he would pick up the necessary items and return to do all the projects in one visit.  He returned about 1 week later and made all the repairs.  I was very happy with his work.

"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."

"UPDATE: The owner of the company, Anthony, called me to apologize for the way his inspector handled my mold inspection and refunded me in full for what I paid. He was very sympathetic on the phone and put an emphasis on how important it is to him to have happy customers. I've since upgraded my rating to a "C"....

ORIGINAL REVIEW: I honestly was expecting a third party non-biased mold and water damage inspection when I bought this company's Water Damage and Mold Test special on Angie?s List. However after having the test performed I feel as though this company?s sole mission was to drum up new work for their mold remediation and restoration business.

First off the inspector showed up to my house late and walked in sporting a bit of a condescending attitude. He also answered several phone calls in front of me during his visit, off to an irritating start. He performed a 10 min mold test with a test swab stick labeled 3M ?Clean-Trace Surface Protein Plus? on an area of my water damaged wall. He told me that if the test turns green there is a ?mild amount? of mold present and if it turns purple then there is a ?toxic? level of mold present. Well the test turned purple within 10 minutes and the inspector then advised me that I should get it remediated as soon as possible and essentially not to wait another day or my family could get sick. He told me that it would cost me about $5,600 for his company to do the remediation work on the section of my wall that showed damage (about 60 sq/ft of wall area) and that they could get started in 2 or 3 days.

I always get a few different opinions and do my research before accepting a proposal so the first thing I did after he left was to look up the 3M test stick that he used. I?ve seen, and personally used, a number of DIY mold tests before and had never seen this test before. On 3M?s website they indicate that this test is a ?Surface Hygiene Test? for use in Food Services & Catering industries for determining the effectiveness of cleaning and sanitation in food preparation areas to help to reduce the risk of food safety incidents! No mention of MOLD anywhere. It goes on to state that the test is used to help to reduce the risk of biological contamination, where proteins and food residues on surfaces could potentially provide nutrients for spoilage or pathogenic bacteria to thrive. Ok so it detects if there is a food source for pathogens to potentially survive on a surface but that doesn?t mean that it detects if there is any MOLD growing there or that it is capable of indicating the quantity or toxicity levels of any mold that might be present which is how the inspector was marketing this test to me. Furthermore the documentation for the test states that the visual color change is an indicator of the level of cleanliness and if the test turns green the surface is clean (not mildly moldy as the inspector told me) and if it turns purple the surface is dirty (not that there are toxic levels of mold present).

I did a little more research and found complaints of other companies on the Better Business Bureau?s website using the same test essentially as a scare tactic to get mold remediation work in air-conditioning ducts and another site warning of a ?Mold Scam? where testers offered discounted coupons for mold testing and again inappropriately used this same test stick. Both sites point out that the only accurate way to really determine the amount, type and toxicity of mold potentially present is through laboratory testing.  I?ve since had a sample of the damaged wall sent off to a laboratory that specifically does mold testing and the results came back as negative for any sort of ?toxic? mold.

Over all I feel like this company tried to play me and is dishonest in their approach and the tactics they use to gain business. I would personally not recommend them or use them again."

House Leveling questions, answered by experts

Polyjacking and mudjacking can both be effective solutions for sinking concrete, but they have key differences. Polyjacking, which uses expanding polyurethane foam, is often considered a better option because the foam is significantly lighter than the cementitious material used for mudjacking. This reduced weight puts less pressure on the underlying soil and lowers the risk of future sinking. Polyjacking is suitable for any sinking concrete slab, while mudjacking is typically only recommended for non-structural concrete, such as sidewalks, patios, pool decks, and driveways. The primary drawback of polyjacking is its cost, which can be up to four times higher than mudjacking—as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.

A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.

Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.

The method involves lifting settled concrete using pressurized cement slurry via drilled holes. This solves uneven surfaces and prevents further settling.

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.
