"So I live in a older house (1947) so the plumbing is older too. Anytime I used my sink dishwasher or laundry the water would all but flood my basement making it almost unusable. I called and talked to Seth he was able to get to my home the next day and diagnose the problem my pipes in the concrete were old and clogged beyond repair well he managed to completely redo all of my plumbing brand new and have it up and running in a matter of a few hours! I now have a dry usable basement. He gave me a very decent price as well! Now hopefully I don't need another plumber anytime soon but if I do I'm calling seth at SWB!"

"Nate communicated with me quickly when I posted my job to fix an outdoor spigot and replace a toilet. He had availability right away, but it turned out that I didn't need him for several weeks. He was able to do the job when I needed him at a very fair price, managed the job well & left things cleaner than he found them. His business is fairly new, but he is a Master Plumber with a lot of professional experience and a very nice guy. We all need a dependable plumber on call, and I've found mine. Hope you'll give him a call on your next job!"

"I have an old farm house. It is at Least 200 years old. It has a stone foundation. Every spring my cellar fills with water. I was given a quote in November on 2022. They installed the water proofing that December. They kept to quoted price with no surprises The crew kept to the schedule I was given. They were professional and left my cellar looking better than I have ever seen it With the soft winter and dry spring I was afraid that their work would not get a good test. However, last night We got four to five inches of rain. In the past this would at least left a foot of water in my cellar. Today it is bone dry. Basement Improvement is a local family run business that I would highly recommend to anyone."

"I bought a fixer upper a couple months back with a leaky basement and moldy smell. After receiving a quote from a competitor that left me feeling a little uneasy. I contacted Rob based on the stunning reviews found on HomeAdvisor. After reading reviews one after the other about how happy people were, I wanted his opinion and expertise regarding my situation. Rob responded immediately, and came by my house the following Saturday morning even though he was going away for the weekend with his wife to celebrate their 30th Wedding Anniversary. He didn't want me to have to wait a week before he would have a chance to swing by. He was not only prompt, but he took the time to explain the process as well as discuss some other things I have going on in my house. His knowledge is astounding in all areas of building and remodeling. Rob assured me that the "smell" in my basement would no longer be an issue, nor would the water. He arrived with his 3 boys to do the job and I must say watching all them work together and interact with each other the way they did spoke volumes to me. A family doesn't get that way by accident...that just tells you the type of character that Rob has, and the kind of person that his wife must be. Real genuine honest good people and I couldn't be more pleased with the job. His price was definitely fair and I no longer have any smell or water in my basement, whatsoever! I would highly recommend Rob and his crew for any job that you need done. He and his boys have the integrity that lack in so many larger companies today and I look forward to more projects in the Springtime."

"I called Octagon the day after we had an upstairs water leak. The next day, Octagan had scheduled a technician to assess the damage and set up the mitigation solutions to dry out the damage before mold could set in. Everyone from Octagon was friendly, professional and very responsive. If you need a fast, reliable and effective response, you will find it with Octagon!"

"Hilltop Drain and Plumbing came to declog the main sewer drain that had backed up in our basement and had started to flood. It was pretty expensive but they did a good job and their response time was quick. $975 for 3 hours emergency plumbing on a Saturday evening. I would hire them again especially since plumbers in Maine seem to be going extinct."

Basement Waterproofing questions, answered by experts

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.
