Experienced professional - Over 35 years of professional contract work completed. I specialize in structural repairs including Field Stone Foundation - Sill Replacements, Lally Columns, Footings, Beam Replacements - Antiques Bought - that are being listed to be sold. I am fully licensed and insured. Services do not include crack or foundation repair.

"Rene is the best! We reached out to Rene about structural issues on our old home. He responded promptly and scheduled a visit within a few days. He knew just what to do to address some sagging floors and areas of the house that weren't correctly supported. He did all the work himself (he sometimes has his son work with him). I have no idea how he was able to complete all the work on his own, especially pouring new concrete footings in a very small crawl space! He is a machine!!! He is meticulous in his work and really goes above and beyond. He left our basement cleaner than when he started!!! He’s a super nice man and it was a pleasure having him work on our house."

We've been serving York County and the Seacoast for over 25 years. Fully insured. All work is warrantied. We take half the quote amount up front and half upon completion. We will also give as many recommendations from brick yards and customers as needed.

"One word: Don't. They replaced the top 6' of our chimney about 7 years ago as well as parging and sealing all of our chimneys and the new chimney is literally falling apart in chunks, the joints are seeping water, and the parging is flaking off. Besides that, while these two jokers were here (and we weren't) our neighbor told us that they were arguing and throwing chunks of concrete at each other. We also found that rather than haul the old chimney pieces away they hid them in the brush beside our lawn. Also, forget about a warrantee. That is B.S."

Formerly known as Mack's Carpentry & Painting General Contractor - We have always provided our customers with all the services they need in order to complete their projects. After 25 years in the Boston area we have now relocated to Louisiana and operating as McKechnie Enteprieses, LlC. Take some time to read the reviews of our customers. Remember, no project is too big or small for us, give us a call.

"I cannot say enough compliments about Mack and his guys! From the first meet until the project was over, they were courteous, respectful of our space, and responsive. I hired them to expand a closet and turn it into a pantry and create a multi-purpose sink/dog wash and install a barn door. I'm so happy with how it all turned out. Bill was our main Jack of All Trades, and he was amazing! Wayne was our plumber, Tommy was our painter, etc. etc. They were all great guys. Definitely will call them again for future projects."

"I requested a quote by email, clearly specifying it was for 2 cracks and sending 4 pictures (2 from the inside, 2 outside) as requested. One crack was twice as long as the other one, very different and salt leftover from water infiltration. I received a quote for $500 which detailed the total cost, without any mention of additional costs. After the technician performed the work in less than 30 minutes, trouble started: he told me he was directed to work on just one, not two foundation cracks. I received a call from the same woman that set everything and she first stated I only request a quote for a crack: I went back to the email and it clearly stated "quote for 2 cracks", she claimed she got confused by the pictures and thought I sent the same crack from different angles. Honestly, they are in the crack business, I don't know how one could get confused by this. She insisted that, despite her making a mistake, I'd need to pay more. I got a call from the owner which argued with me about paying $350 more, that the quotes I got from other companies were also about a single crack, that their quote has different pricing per crack (I verified, it did not, there was just a single price). After I mentioned this seemed to me a bait and switch technique, he argued some more but in the end agreed to accept the quoted price."

Foundation Repair questions, answered by experts

Water damage in your home’s foundation is gradual, often beginning with small cracks that let water seep in. Over time, this weakens the foundation, which then allows in more water, causing significant structural damage. This process can take months or years to destroy your foundation, and the repairs can be very costly. Have your foundation inspected regularly to prevent significant damage.

Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage.

Always hire a foundation repair contractor the moment you suspect your house doesn't have a good foundation. The longer you wait to address foundation issues, the more likely they can lead to bowing floors, cracks in walls and ceilings, sticking doors and windows, chimney and roof problems, and more. Foundation problems can also let moisture into your home, leading to water damage, mold, and mildew problems.

Yes, you can live with a cracked foundation—in fact, most people do. Virtually all foundations crack from normal settlement, and while settling cracks benefit from sealing to prevent water and moisture intrusion, most aren’t an issue. If you have structural cracks in your foundation, it might be safe to live in your home for some time, but you should address them immediately to prevent structure collapse and major property damage.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.
