"Our experience with Tullo's Home Improvement was good. Mike was very willing to work with us and take the time out of his schedule to meet with us a few times before we made a decision. After all the work was done, we realized that we made the right decision. Work was completed and very professional; once the work was done you couldn't even tell, except for a very nice new roof. Everyone at Tullo's Home Improvement that we have had contact with during this project was very pleasant, understanding and respectful. This was definitely a great project with the help of Tullo's Home Improvement."

"I have now had 4 pickups from this company. Each time it has been with different items: I have had my kitchen remodeled,  a deck torn down and rebuilt, a new roof put on, old fencing disc arded, and a yard cleanup. The only difference in pricing was for the roofing and even though ti was more money it was STILL CHEAPER than a dumpster!!! I don't know how these guys do it, but they pickup on time, without issue andfor the cost quoted. I have turned each of my contractors onto them - now they are using them. SO MUCH cheaper and better service than any dumpster company I have used!"

The first step involved trenching the inside perimeter of the basement slab, which was relatively new and required substantial work with jack hammers (very dusty and noisy). The trench was about 18" wide and 18" deep to accommodate the perforated pipe and the surrounding material consisting of hard plastic "peanuts" to facilitate drainage.  Workmen also installed corrugated plastic on the vertical wall surfaces so that should any water enter higher up on the wall it would be directed into the trench. The trench was then covered with a clear plastic vapor barrier, after which cement was floated over everything and leveled with the rest of the slab.  NOTE: the trenching is very destructive and the workmen will remove any finished elements - baseboard, sheetrock, framing, carpet etc. - to access the walls and foundation. Be prepared to budget repair work on any already-finished areas once the work is done.

The team was invariably punctual, thoughtful and kept the work area clean. Charlie stopped by regularly to ensure the project was moving along as planned and helpful throughout. When finished, the crew cleaned up well and left the site in good shape, although it took some time finally to get rid of the dust.  My only disappointment was that the backup batteries were left in their cases on the floor, when it seemed that they should have been up on a shelf away from harm.

The good news is that our basement has not seen any moisture since the system was installed.  We've experienced some bad storms combining rain over frozen ground and snow and water clearly was getting through the foundation.  We saw the pumps moving significant amounts of water out of the house and the system has been completely reliable.  Finally we were able to finish the basement as we'd hoped because we're confident the drainage system is protecting the investment.

"After getting a really late (several days) or no response from two other plumbers, I contacted Griswold plumbing after finding them here. Jeremy called me back immediately, listened to my concerns and scheduled me for two days later. The other plumber that actually returned my call needed a week after missing the first appointment. Jeremy showed up and identified the issues with my hot water and quoted me a very fair price for the amount of work he ended up having to do on my neglected plumbing. He was friendly, quick, honest, and professional. He had everything completed within a reasonable time and my hot water never worked so good. I decided to go with him again for another project I need help with and I will keep Griswold Plumbing in mind for my next home. The reviews really show what great service these guys provide!"

Basement Waterproofing questions, answered by experts

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.

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.

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.

Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to water-damaged concrete.
