"I have an extensive experience with Finn's builders (Chris, James, and Kenny) Over the last 3 years they have revamped my ranch style house with innovative ideas, and expert solutions: rebuilding walls and floors of a veranda, redesigning the interior stairs to the basement. They painted and re-organized the garage. They installed Anderson windows in 2 bedrooms and 2 bathrooms They repaired a walking shower, came up with a clever solution for an uncomfortable shower system. Likewise, they installed electrical outlets and lighting in the living rooms and painted 3 rooms with maximum efficiency and minimum fuss. I like their working style and their ingenuity. I rely on their team for keeping my house in shape and my mind at peace. I recommend them without reservation."

"DryZone Basements kept me up to date on my Appointment, called the morning of, arrived on time, checked in with me at the beginning to review scope of work, set up a dust barrier, two (2) workers and the job lead, worked hard throughout the time here. The lead would check in with me in intervals, they were open to answering any questions. Upon finishing, the lead took me around the whole job, explained the work, and allowed me to ask any questions, and provided me responses, and cleaned up the work area very well. Hopefully, we will never have to use, but definitely worth the piece of mind. Thank you."

"The work performed was incredible. AJ and his team are real pros. The cost for all of the work they performed was more than reasonable. AJ came out for an estimate and explained the work he was going to do and gave me options on what different things he could do to help me out. He kept my wife and I in the loop every step of the way during the project. In addition, the crew didn't rush the job. They made sure the job was done right. Before the work was performed our basement would flood very easily when it rained. After the work was performed it rained and the basement was bone dry. This was a huge relief. Not having to mop up water every fifteen minutes was wonderful. Our sump pump doesn't run half as much as it used to. Basically, my wife and I are thrilled with the work performed and highly recommend AJ and his team to anyone

"I've come across some very unprofessional contractors. I would say 90% of the contractors I have dealt during the remodeling of my home never called back or looked at my job and never returned an estimate as promised. The good news? ALL PRO Waterproofing isn't one of those companies. They were AMAZING. They sent someone to give me an estimate immediately - they called quickly to conform the install and they always showed up on time and ready to go. ** I would have given them 5 stars, but I found the price a little too high - but other than that - if you need basement waterproofing done right, don't waste your time with anyone else and call A"

Basement Waterproofing questions, answered by experts

Delaying basement waterproofing in Amherst can result in foundation settlement, frost heaving, and accelerated concrete damage from acidic soils. Persistent moisture can trigger rapid mold growth and poor indoor air quality, especially with high humidity. Water intrusion may also elevate radon levels and increase energy bills. Neglecting small leaks often leads to extensive repairs after harsh winters or heavy spring storms, making projects more disruptive.

Helpful?

For minor basement waterproofing concerns in Amherst, start by thoroughly drying the area and inspecting for hairline cracks under 1/8 inch wide. Seal these with hydraulic cement or polyurethane caulk, ensuring surfaces are clean and dry. Maintain clear gutters and downspouts, and check that foundation drainage slopes away from your home. Always wear gloves and a mask, and avoid DIY repairs if you spot mold, structural movement, or persistent dampness.

Helpful?

Amherst homeowners increasingly choose integrated solutions, such as combining interior French drains with exterior foundation drainage systems for maximum protection. Smart sump pump installation with battery backup and remote monitoring is popular due to local power outages. Eco-friendly vapor barriers, radon mitigation integration, and seamless wall panels that allow for future basement finishing are also trending, offering both efficiency and long-term flexibility.

Helpful?

To keep basement waterproofing projects in Amherst safe for kids and pets, designate work zones with temporary barriers and ensure all tools and chemicals are stored out of reach. Choose low-VOC sealants and slip-resistant finishes, and ventilate the area thoroughly. Opt for sump pump covers with secure locks and schedule noisy work when children are away. Wait for all materials to cure before allowing family access.

Helpful?

Amherst’s freeze-thaw cycles, heavy spring rains, and snowmelt can intensify basement water intrusion and foundation drainage issues. Schedule major waterproofing or sump pump installation from July to September, when the ground is driest. Winter’s temperature swings can worsen cracks, while summer humidity increases condensation. Planning around these patterns helps ensure waterproofing materials cure properly and reduces the risk of weather-related setbacks.
