"It comes out exactly what I’m expecting. My basement stays dry until now problem solved without the inconvenience of a construction noise in your basement. The duration of the job is very minimal and the price is reasonable. Very professional."

"I would like to express my most sincere gratitude to this company for the excellent work they performed in replacing the bathroom in my home. From the very first moment, they proved themselves to be highly responsible, punctual, and professional. The quality of their work exceeded my expectations; they paid attention to every detail, and the final result turned out beautifully. Their dedication and commitment to what they do are truly evident. Without a doubt, I recommend them 100%. It is difficult to find people who are this reliable and committed nowadays. Thank you so much for doing such an impeccable job. If you like, my dear, I can personalize this with the name of the company or the person who did the work for you, to make it even more special."

"Barrett's Plumbing saved me a ton of headaches and money. Every 2-3 weeks I used to have to call someone to pump or clear my drain, ranging anywhere from $250-$300. Barrett's Plumbing was the only one to actually realize that I needed a whole new septic tank. Finally I no longer have to worry about any backups or flooding in my house."

"Work was done ok however, on follow up when I wanted lines drawn in parking area, no one responded to multiple calls. As a client, even IF they were not available to do this part of the job, I deserved a return call. Had there been a problem, I’m concerned that they would not have responded to that either. Poor communication is the reason for low ratings"

Basement Waterproofing questions, answered by experts

Generally, moisture barrier padding costs $0.75 to $1.50 per square foot, varying by brand and mix. That’s a lot more than standard padding, which runs $0.25 to $0.90 per square foot. The price difference between these two options might seem steep, but think of it as insurance against future carpet replacement costs and subfloor damage. If you have pets or kids, that extra investment in high-risk areas like your living room often pays off.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.

A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.
