Licensed & Insured Independent Pros
Excavation work carries real risk, so calls go to independent contractors with liability coverage and licensing where required. Confirm they carry coverage for heavy equipment.
For finished basements you don't want torn apart, exterior waterproofing keeps water off the wall entirely. One call connects you with a licensed, insured independent contractor in Norcross who does it right.

Exterior work is the only method that keeps water off the outside face of the foundation. For a finished basement with drywall, built-ins and flooring you just paid for, that difference matters. Tearing out the bottom of every wall to install interior drain tile can cost almost as much in restoration as the waterproofing itself.
Exterior work also makes sense when the wall itself is deteriorating. Old block foundations with crumbling mortar, poured walls with honeycombing or stone foundations that let water through every joint all benefit from being exposed, repaired and sealed from the outside. Once the wall is open, the contractor can fix cracks, parge the surface and replace a collapsed or missing footing drain at the same time.
The downside is the digging. Exterior waterproofing means excavating a trench along the foundation, sometimes six to nine feet deep. Landscaping, walkways and decks near the wall have to be removed or worked around. The contractors we connect you with in Norcross plan for that up front and include restoration in the quote.

The membrane gets the attention, but the drain at the footing does much of the real work. Water that reaches the wall runs down the drainage board to the footing. If nothing carries it away, it pools there and builds pressure, the same pressure that caused the leak in the first place.
A proper footing drain is perforated pipe laid with a slight, consistent slope, bedded in clean stone and wrapped in filter fabric so silt can't clog it. It has to discharge somewhere reliable: to daylight on a sloped lot, or into a sump pit that pumps the water well away from the house. Many older homes either never had one or have one that collapsed or filled with clay decades ago.
Ask your contractor exactly where the drain will outlet and how they'll confirm the slope. Laser levels make this precise. A cleanout access point is also worth asking about, since it lets the drain be flushed in the future without digging.
Request pictures of the drain and board before the trench is filled. Once the trench is filled, the only way to check the work is to dig it up again.

You want a contractor who treats excavation with the respect it deserves.
Excavation work carries real risk, so calls go to independent contractors with liability coverage and licensing where required. Confirm they carry coverage for heavy equipment.
Quotes are written per wall or per linear foot, with excavation, membrane, drainage board, footing drain, backfill and restoration listed as separate lines.
Contractors who work locally know the soil, the permit process and how to schedule around weather.
Mini excavators, trench shoring or boxes for deep cuts, pressure washers for wall prep, spray rigs for membranes and laser levels for drain pitch.
Every stage, from digging to final grade, affects how long the system lasts.

Before any digging, buried utilities are marked through the local call-before-you-dig service. The trench is then dug down to the footing, with shoring or sloped sides for deeper cuts so the crew can work safely.
Once exposed, the wall is cleaned, cracks are repaired and block is parged smooth, giving the membrane a sound surface.
A rubberized fluid membrane or self-adhered sheet goes on from the footing up to grade level. Thickness is checked as it's applied so it performs as rated.
Drainage board protects the membrane and leads water to a new gravel-bedded footing drain with a reliable outlet.
Clean stone goes in against the wall, topped with soil compacted in layers and graded so the surface slopes away from the house for at least several feet.
Topsoil, seed or sod and reset pavers finish the job. Confirm what's included and how later settling is handled.
Exterior waterproofing is priced mainly by how much wall gets exposed and how hard it is to reach. Depth matters, since a full-height basement means a deeper trench and more soil to move and store. Access matters too. A wall with open lawn beside it is far easier than one under a deck, beside a driveway or tight to a neighbor's property line, where hand digging or smaller equipment may be needed.
Wall condition changes the price once the foundation is exposed. Clean poured concrete needs less prep than old block with failing mortar or stone that needs repointing. Then come the membrane system, the drainage board, the footing drain and its outlet, and finally backfill and restoration. A good quote prices each of those separately. That makes it easy to compare offers and to see the cost of doing one problem wall now and others later.
Timing can affect the price as well. Spring is the busiest season for exterior work, so lead times are longer, while late summer and early fall often bring drier soil and easier scheduling. If one wall is leaking badly and the others are only damp, some homeowners start with the worst wall and plan the rest for a later season, which spreads the cost without leaving the main problem unsolved.
A clear plan keeps an excavation job on time and on budget.
Call +1-866-476-1348 and describe the leaking walls, the interior finish and any decks or patios along the foundation.
A local independent contractor schedules an on-site assessment, usually within a few days, sooner if water is coming in.
The contractor inspects both sides of the wall, checks grading and drainage, discusses access and restoration, and gives you a written quote for each phase.
After utilities are marked and any permits are in place, the work is completed, the yard is restored and the contractor walks you through the warranty and the drain outlet.
One call connects you with a local independent pro who seals foundations from the outside.
Call +1-866-476-1348We'd just finished the basement when the back wall started leaking. The contractor dug that side, sealed it and put in a new footing drain. Not one drop inside since, and the drywall never had to come down.
Heather S., Norcross
Our stone foundation was over a hundred years old and wept everywhere. They exposed the worst two walls, repointed and parged them, then applied a membrane. The basement smells like a basement should now.
Leon M., Norcross
What I appreciated was the planning. Utilities were marked, they shored the trench properly and they put plywood down to protect the driveway. The yard looked great after.
Joan D., Norcross
The old footing drain was crushed and full of clay. After the new system went in, the sump barely runs.
Raj P., Norcross
Down to the footing, which for a full basement is often six to nine feet below grade. Deeper trenches need shoring or sloped sides for safety.
A single wall often takes two to four days, and a full perimeter can take a week or more, depending on depth, access and weather. Membrane cure time and inspections can add time.
It stops water before it reaches the wall, which interior systems can't do. It also costs more and disrupts the yard. For many homes, interior drainage is enough; for finished basements or failing walls, exterior is often worth it.
Excavation is possible in many winters, but frozen ground slows digging and most membranes need temperatures above a minimum to apply properly. Many contractors schedule exterior work from spring through fall.
Plants, pavers and soil along the trench line are removed and either set aside or replaced. Ask what restoration is included and whether the contractor will return to top off soil that settles.
Many local building departments require one, especially when drainage tie-ins or structural repairs are involved. Ask the contractor who pulls the permit and whether an inspection is required before backfill.
Calls from across Norcross and surrounding areas go to local independent contractors who handle excavation and exterior sealing. Block, poured and stone foundations are all covered.
Contractors who work in Norcross know which neighborhoods have heavy clay, high groundwater or tight lots between houses, and they plan excavation and equipment access around those conditions from the first visit.
