Discover the Difference with 603 Basement Solutions
Basement waterproofing solutions are types of waterproofing systems that help your house keep the basement safe and dry.
Your basement is the foundation of your home. Think of it as a sponge, absorbing all the water coming in contact with your foundation and pushing that moisture into your walls, floors, and ceilings.

That’s where we come in! We have helped thousands of homeowners in New Hampshire, Maine, and Massachusetts to improve the health of their basements, and even the health of their loved ones, by making sure that water and moisture in your basement are a thing of the past!

Say "Goodbye" to leaky basements for good!
If you’ve ever noticed puddling or seepage from the wall/floor joint, or on the floor in your basement, then your home is in need of a quality basement waterproofing system.

When the ground slopes downwards away from the home's foundation, it means your house is at the bottom of a hill, and there is a high chance that rainwater will run under the foundation and into the basement.
If your home is located in an area that has a high water table or is near a body of water, such as a river, wetness may enter your basement through cracks in the walls.
At times, soil from trees and plants can clog up drain pipes leading to your home's sump pump which will cause flooding in your basement and create humid conditions favorable for mold growth.
Rainwater seeps in through the foundations and walls that are not properly waterproofed.
Water sources such as basement windows, broken pipes from the laundry room or sinks, and floor drains. Also, the condensation from moisture in the home like humidity from HVAC systems and water piping systems.
Improper grading around the home can cause improper drainage of water away from the house which can lead to a wet basement.
What is Basement Waterproofing?
Basement water is a serious problem because it can cause structural damage, mold, and structural collapse. This is why it is important to get proper basement waterproofing services done and it’s a specialty of 603 Basement Solutions.
Water entering the basement is not just a problem for homeowners but also for builders and engineers. This type of water intrusion can cause structural damage to the home, create hazardous living conditions and increase energy costs.
Basement water comes from various sources and if you’re tired of the problems it’s causing your home then you can completely solve your basement water problem by having a qualified basement waterproofer come in and assess the situation. That’s where 603 Basement Solutions steps in!
Basement Waterproofing is the process of waterproofing a basement so that water will not leak in from the ground, walls, or floor. This helps to prevent mold growth and can help to prevent the development of other illnesses caused by high humidity in your home and possessions.
There are two major types of basement waterproofing systems: the exterior and interior methods.
Exterior waterproofing involves building an impermeable wall along the foundation perimeter to keep water from entering the basement walls and floor. The exterior walls should either have a sloped drainpipe or be at least six inches above ground level to allow for drainage runoff.
Interior methods involve sealing cracks in the concrete foundation, installing drainage pipes along the walls, and/or installing wallboard on all walls inside of the basement to prevent any water infiltration.
With that being said, there are various ways to stop water from coming into the basement. You could add a sump pump to the drain, install a French drain system, or use a watertight door to prevent water from coming in. But the only way to guarantee your basement stays dry and able to be used for future plans in remodels and finishing your basement is by getting your basement waterproofed by professionals who’ve seen it all and done it all like 603 Basement Solutions.
Basement waterproofing is essential for homeowners in Portsmouth, NH, due to the area’s specific environmental conditions. The coastal climate and varying soil types can cause excessive moisture around homes, leading to water infiltration in basements.
This can result in mold growth, structural damage, and a decrease in property value. Waterproofing your basement ensures a dry, safe, and healthy living environment. At 603 Basement Solutions, we understand these local challenges and offer tailored solutions to keep your basement dry and protected.

Portsmouth basement waterproofing — local context
In Portsmouth (Rockingham County), your basement fights tidal water, not just rain. The Piscataqua is a tidal estuary running ~4 knots through Portsmouth Harbor — one of the swiftest rivers in the U.S. (Wikipedia, citing USGS/NOAA) — so the water table rises and falls with the harbor. The City's own Coastal Resilience Initiative models tidal flooding along the Piscataqua and Sagamore Creek and plans for ~2.5 ft of sea-level rise by 2100, lifting the coastal water table against your foundation. Near-shore lots sit on USDA-NRCS Squamscott marine soils — fast on top, then perching water on dense clay subsoil. FEMA also maps AE/VE flood zones along the waterfront, with floodplain permits run by City Planning (1 Junkins Ave). For Portsmouth's old fieldstone foundations, we install the interior Forever Dry System — full-perimeter drain, a ½ hp sump per 120 ft, wall vapor barrier, and a dehumidifier. We don't dig outside; interior is the durable fix. Basement waterproofing runs $3,000–$30,000.
What a recent customer said
With the crazy wet weather and super high water table this year. Had water just seeping in through the Wall/Floor Joint in basement, that would just NOT stop. … But was leaking in at several points along a 30ft wall. 603 Basement was just a bit more. BUT they put in their patented Channel solution along the entire base of the wall, along with Sump Pump And let me tell you. . IT really worked. — John Weber, 5★ (Google review)
Frequently asked questions
Why do Portsmouth basements stay wet even when it isn't raining?
Because Portsmouth is tidal. The Piscataqua River is a tidal estuary running about 4 knots through the harbor (Wikipedia, citing USGS/NOAA), so the coastal water table rises and falls with the tide and pushes against your foundation. The City's Coastal Resilience Initiative plans for roughly 2.5 ft of sea-level rise by 2100, which only raises that water table further. That's groundwater pressure, not weather — so an interior perimeter drain and sump that manage the water table beat any one-time patch.
Why does water pool against foundations on Portsmouth's near-shore lots?
Many waterfront and North Mill Pond lots sit on USDA-NRCS Squamscott marine soils — very deep, poorly drained soils where water moves fast through the sandy upper layer, then slows on the dense clay-rich subsoil (22–35% clay). Water perches on that clay and presses against the foundation. Our Forever Dry System collects that water with a full-perimeter interior drain and routes it to a ½ hp sump per 120 ft, rather than fighting it from outside.
Is my Portsmouth home in a flood zone, and who handles permits?
FEMA maps high-risk AE flood zones along Portsmouth's waterfront, North Mill Pond, and Sagamore Creek, plus oceanfront VE zones; check the FEMA Map Service Center or NH Flood Hazards Viewer for your parcel. Floodplain permits run through the City Planning Department at 1 Junkins Ave, (603) 610-7216 (City of Portsmouth Floodplain Regulations, Zoning §10.620). We handle the interior waterproofing; the City handles any floodplain permitting.
