"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 a hostage. Even Air b and bs offer full refunds on deposits within just a few days of their arrival date. 3 days to cancel with service not scheduled for 6 weeks out, Come on 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 the 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 over 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 did not 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 nice enough. No answer. No callback. I will never seek out their services again and I will actively discourage others from doing so but, based on my experience, I expect they do not care."

French Drains questions, answered by experts

Several signs can tip you off to a clogged dishwasher drain. At first, you may notice that it’s taking longer than usual for the dishwasher to drain, or you may hear gurgling sounds during the draining part of the cycle. You might also notice water backing up into your sink or excess food at the bottom of the dishwasher after a load. The most obvious sign, though, is seeing standing water at the bottom of your dishwasher after the cycle has finished.

No, it is not advisable to spray pesticides down the drain in your home. Most drinking water and wastewater treatment systems are not properly equipped to remove pesticides. Should pesticides infiltrate waterways, they can cause harm to plants, fish, or other living things. In most areas, pouring pesticides down the drain is illegal due to the potential harm it causes. 

If the drain pump on your washing machine is continuously draining, it could be that the control board is damaged and requires repair, or there’s a clogged or kinked drain hose. If you can’t locate the problem, you’ll want to have a plumber or appliance repair expert come take a look.

Unlike regular cleanings, snaking your sewer line should be done as needed. There’s no reason to snake your sewer line if you don’t have any noticeable issues, like slow drainage or plugged drains. You can add it to your regular sewer cleaning checklist as a prevention method (on the same 18- to 22-month schedule), but it’s not always necessary. 

To unclog the drain pipe, remove the machine's drain hose from the pipe or sink drain, being careful to contain any water in it. Next, use a plunger for sink drains or a plumbing snake for a wall drain. Test the repair by pouring a small amount of water into the pipe before trying it with a laundry load.
