"I strongly caution anyone considering doing business with this company. I gave them a deposit of $4,428.65, and when I canceled a week later they kept almost $900 of it even though my service was not for another 6 weeks. You do sign a very simple, clearly stated document that says, “Should you cancel beyond three business days, you understand your deposit is non-refundable. Northern Basements may choose to refund depending on cancellation circumstances.” I fully acknowledge that I canceled a few days outside that window, but I hoped an honest company that cares about customers and referrals would choose to provide a full refund. I am a sucker for hoping that. They chose to risk my impression, referral and review for $885.53. If nothing else comes out of this, I hope everyone reading at least goes in knowing that this statement on their contract is a real threat and your deposit is hostage. Even Airbnb’s offer full refunds on deposits within just a few days of people’s arrival date. 3 days to cancel with service not scheduled for 6 weeks out, “C’mon man.” No materials were used. No service workers’ time was taken. The manager justified the 20% withholding as credit card fees, restocking fees, time and resources for the estimate, and administrative fees. I wholly accepted responsibility for the credit card fees and time of Paul, the gentleman who performed the assessment, and I offered to settle at 10%. I still believe any reputable company would have provided a full refund at this point in a project, or at most deduct the credit card fees, because nothing more went into this beyond what would have normally been a free estimate. The further arguments the manager made for the additional fees were the scheduling of their team and allocation of materials for my project. Complete nonsense, especially when the project was not set for 6 weeks away. Because they had my deposit hostage, they had control of how much they decided they wanted to keep, it was completely arbitrary, and they kept almost $900 of my money without providing anything. If they wanted to cover their credit card transaction fees, fine, at most 6%, but the rest is absolute robbery. The only solace I can find in this loss of almost $900 now is that I didn’t spend another $13,000 with them. I tried to call Paul after speaking with the manager to ask if he could do me a favor and try to reason with the manager on my behalf because he seemed like a nice enough guy. No answer. No call back. I will never seek out this company’s services again and I will actively discourage others from doing so but, based on my experience, I expect they really don’t care."

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."

Basement Waterproofing questions, answered by experts

Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

Crawl space encapsulation can make repairs more complicated, particularly if you have plumbing or wiring surrounding your crawl space area. Additionally, some home designs benefit from the additional airflow that crawl spaces with vents provide. Vents are no longer an option after encapsulation. Always talk to your crawl space contractor to ensure the pros outweigh the cons before investing in the installation.

In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.
