"I had a bathtub removed and replaced with a walk-in shower. First, they should state that they hope to finish in one day, not advertise as a one-day replacement. I say this because there were only two men working on this project and had there been three, they could have finished in one day. Each time something had to be removed from the bathroom, the second man had to stop what he was doing to help the first. Slowing things down considerably. Also, pre installation day, the actual workers should come out to look at what has to be done, since the sales people are not crafts people. One last thing, they used the wrong sized pipe when piping the drain in the basement (not following 248 CRM 10, Massachusetts Uniform State Plumbing Code). I didn't know this until I had a plumber in to do some work and he pointed it out. In all, I am glad I had the work done, I just wish it had gone more smoothly considering the price."

"Just finished a visit with Foreman Doug and his crew, Devin, Sean, and Mason. Waterproofing the basement and super sound and solid work! Doug was professional and very good at keeping me in the loop with the project over the 3 day visit, and created a solid system that we are confident will keep water out of the basement forever. Above and beyond as well with problem solving when having to find solutions to fit our basement layout, all with a solid financing option/great price and 5 year warranty/ yearly inspection plan. If you are stuck with water in your basement, get Groundworks working for you ASAP!"

"Very well. Craig was very conscientious about my needs and opinion, checkin with me regularly. Working on an old house has a unique challenges, but Craig and David worked together to find solutions. Craig was also a wealth of information for me regarding the finishing touches that I plan to do."

"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

Beyond keeping the entire plumbing system flowing, plumbing vents also help control gas and odors from entering the home. These vents also allow fresh air to enter your plumbing system, which helps improve water flow. A sure sign the plumbing vent is failing or needs repairs is if there’s a strong sewage scent coming from multiple points of the home.

On average, a plumber will take 30 minutes to two hours to clear a clogged drain. If the clog is located close to the drain or an access point and isn’t severe, the project will take about half an hour. If the clog is deep within your plumbing system or is a severe blockage, it can take two or more hours to remove the clog. For this reason, main line clogs tend to take longer, usually between two and three hours.

To keep a walk-in tub in good condition, clean it regularly with non-abrasive cleaners. It is also important to periodically inspect the seals, jets, and faucets to ensure they are functioning correctly.

Repiping your plumbing is when you remove the old plumbing system and replace it with newer, more modern plumbing and drainage pipes. Typically, older homes are repiped to upgrade the plumbing system. If you have frequent issues with your home’s plumbing system or live in an older home with outdated pipes, consult a professional plumber about the best course of action for repiping your plumbing.

Left unattended, a leaking toilet will eventually cause water damage or mold growth. If you’re a homeowner, you can file an insurance claim for water damage. However, that can be a long and tedious process; sometimes, your insurance company may not cover the damage. Therefore, it’s always best to fix any leak you notice right away if you can.
