"They weren't able address part of my project which included fixing a bulkhead wall, and masonry. I wanted to have it all addressed project by project and discovered that there was more damage to one of the walls that needed fixing. As they weren't concrete 'masons', they wouldn't be able to fully address that before installing a drainage system. It was all within my budget. I just didn't want to have the drainage system installed and have it fail because due to the mortar crumbling. The person that went to my house spent a considerable amount of time. He was knowledgeable, courteous, and not pushy. It wasn't until I had another contractor come through that I realized that what I had initially planned on was not going to work. When I went to cancel, the person that handled my estimate was concerned that I was cancelling and that I was being given "bad advice" from another contractor. I thanked him for the time he spent, and the information that he gave me, and sent my cancellation form. I would have hired them had they been able to fully address the entire project(s)."

"Bill was great to work with! He did such a great job. He was very honest and had great ideas. He was extremely professional and kept to his word. He showed up on time and completed the project in a timely manner. His prices are reasonable and fair. I have several future projects lined up with Blake Mountain Home Improvement. I can't say enough great things about Blake Mountain. As a matter of fact I still talk to him!!"

Plumbing FAQs, answered by experts

Signs of a broken drain pipe include slow-draining sinks, tubs, or toilets; foul odors coming from the drain; damp or wet spots on your walls, floors, or ceilings; and gurgling sounds coming from the drain. In severe cases, you may also notice a sudden drop in your water pressure.

In general, PVC (polyvinyl chloride), PEX (polyethylene), and copper are the three piping materials used in new constructions when adding water supply lines. There are some caveats. PEX and copper are considered ideal when running lines that will handle hot water because they are not at risk for melting and warping the way that PVC piping can. At $0.40 to $4 per linear foot, PEX is considered more affordable than copper pipes, which cost $2 to $12 per linear foot. PVC is considered appropriate in water lines for cold taps only.

Applying drain cleaner is a common DIY solution to clogged drains, but it can be extremely harmful to your pipes and lead to corrosion and leaks. It is almost always better to try snaking a clog than using a drain cleaner, but the best solution is to hire a professional plumber. They can locate the clog and gauge the severity using a camera system and then decide if using a plumber’s snake, auger, or drain cleaner is the best option to remove the clog and limit damage to your plumbing system.

Most of the time, homeowners are responsible for replacing a main water shut-off valve. This is because the property owner also owns the water service line from the shut-off valve near their property line to their house. That means they must maintain, repair, or replace it when needed.

No, you should avoid using liquid drain cleaners. These chemicals, often packed with sulfuric or hydrochloric acid, can wreak havoc on your pipes, causing erosion and potential leaks. They’re also dangerous to your health. If you’re dealing with a stubborn clog, manual removal or a professional plumber is your best bet. Chemical drain cleaners can often make things worse, especially if the clog stays put and the chemicals linger in your pipes.
