"We just had American Dry Basement install a waterproofing system in our basement. We've had issues with water in our basement and needed a total solution so we can sleep at night and go away without worrying about flooding. Steve T from American Dry came to our house and presented us with what the solution will look like and thoroughly explained the entire process. He also answered all our questions and was always available to talk to. He is extremely knowledgeable and an excellent professional to work with. Then Wilson and his two-man crew came to do the work and they were all professional, extremely hard working and respectful of our home. They always started early and worked all day long to get the job completed. They wrapped up all items that were still exposed after we cleaned out most of our basement, used vacuums and filters to minimize all the dust and left our basement cleaner than it was before. We highly recommend American Dry Basement Systems and we're so happy we chose them over the others we received estimates from. And their price was more than competitive for what we believe is a much better solution."

"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."

"It went well! I expected it to take a long time to get it picked up, but I called for the bag to be emptied on Friday and they were here Saturday! I am already filling it up again. (We have a MESS from the storm and need to finish the kitchen before this weekend's company coming in from out of town.) I have already called them to request my bag be emptied on Friday, and they have me on the schedule! I can't believe the customer service is so great! This is not a regular dumpster company. I have a dumpster delivered last summer and they gouged my driveway. What a nightmare it was to get them to pay for the driveway to be fixed. NEVER AGAIN! It's BullBag only for our future needs."

"

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

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they’re tightly laid on top of each other, creating the effect of a firm wall against accumulating water.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.
