"First let me start withâ ¦I know all of the tradesmen and women are BUSY! Thereâ s never not a need. I respect that. I also value my own time and money. Being a homeowner is stressful and when something goes wrong, you need support and someone you trust that can help you. Iâ m a single mom and I work hard for all that I have. When I began to have a major plumbing issue, I was stressed!!! My home was built in 1900. It has a single pipe drain system to the city sewer. It became clogged (very slow moving) and guess what began slowly backing up into my basement?! You guessed it! Everything being flushed from my home. 𠤢 I called SIX plumbers. You know how many called me back? One, Royal Flush. (Again, respectfully..I understand how busy they are, but just a call back saying I canâ t would have been more helpful than radio silence) I called Royal Flush, left a message. Within minutes received a call back. By the end of the conversation, they would be here this afternoon!!!! What?! No way?! Today?! And guess what else??? They showed up, when they said they would. So informative. So kind. So professional. My stress and anxiety are gone and I can breathe easy again. Listen, owning a home is expensive but Iâ m more than happy to spend my money on quality, professionalism, and a company I can count on! Thank you Royal Flush for helping this mom out and removing some extensive stress!!!"

"Eastern Maine Drainage was quick to assess our problem and Nate was able to set up an appointment within a few days to remedy our drainage issue. He was on time, communicated clearly, and was tidy with his work. Since I was at work while he was installing the new sump pump and drain line, he kept me in the loop about his progress. He had a detailed estimate that he stuck to, and he even deducted the cost of some PVC when he realized he didn't need as much as he initially planned. I would recommend him to anyone needing work in their basement."

"Everything went wonderfully with this company.  They were very professional, listened to exactly what my problem was, and explained to me how they were going to diagnose the problem and/or solve it before doing any actual work.  Once they started, the team (three people came) worked together like a well-oiled machine.  One was in the room with diagnostics, one was at the fuse box looking for possible problems there, and the third went into the crawlspace beneath our house to look at the physical wiring.  Once the problem was found (there was a faulty wire beneath the house that had come loose from the junction box), it was fixed and tested within minutes and another full diagnostic was done to make sure there were no other possible issues.  They cleaned up after themselves very neatly.  They also replaced the light switch with a dimmer switch at no extra cost!  Well within my budget, and came in even lower than their original (FREE) estimate!  I would highly recommend this company to anyone in the Bergen County area.

Basement Waterproofing questions, answered by experts

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

In perfect conditions—meaning, no overexposure to the elements without roofing material on top of it—an ice and water shield can last for decades. In fact, many come with a limited lifetime warranty because they should last for a long time. If, however, the membrane is exposed to the elements during building or if there is a delay in installing the roofing material, it might only last up to 180 days if exposed to the elements. The key is to make it a layer of protection and then protect that layer by installing the roofing.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.
