Local Waterproofing Specialists in Delaware
SMG Plastering INC provides professional waterproofing throughout Delaware, USA. Our crews work out of 830 Crum Creek Road, Media, PA 19063, so Delaware projects get an owner-supervised team that already knows the neighbourhoods, the building stock and the conditions that cause waterproofing problems here.
A wet basement is rarely one problem — it's a drainage system that stopped working. SMG Plastering INC waterproofs basements, crawlspaces and foundations across Media, Chester, Upper Darby and Delaware County using a diagnosis-first approach: we trace the water path from grading and gutters to footing drains before recommending a single product.
Northern Delaware is a short run down I-95 from our Media headquarters, and we've built a steady base of commercial and residential clients in Wilmington, Newark, Claymont and New Castle County. Warehouse and office exteriors, historic brick in Wilmington's older districts, HOA communities and single-family homes all fall within our regular service area.
Every Delaware project begins with a free on-site assessment and a written, itemized proposal within 24 hours — covering preparation, materials, schedule and price with nothing hidden. For water, mold and storm emergencies in Delaware, USA, we answer 24/7.

Frequently Asked Questions
Waterproofing in Delaware — Questions, Answered
Should I waterproof my basement from the inside or the outside?
Exterior waterproofing addresses water before it reaches the wall and is the most complete fix, but it requires excavation. Interior systems manage water that has already entered and are less disruptive and less expensive. We recommend based on your water source, soil and budget — not a one-size-fits-all product.
How much does basement waterproofing cost in Delaware County?
Cost varies with linear footage, wall condition, and whether excavation or a sump system is needed. Targeted crack injection is a small job; a full perimeter system is a larger investment. Your free inspection produces an itemized number with no surprises.
Will waterproofing stop my basement humidity and musty smell?
Usually, yes — when it's paired with the right dehumidification and vapor barrier. If mold has already established itself, remediation must happen first, which our team also performs.
Do you travel to Wilmington and Newark, DE for residential jobs?
Yes. Northern New Castle County is within our standard service area, and estimates there are still free with a 24-hour turnaround.
Can you handle large commercial painting contracts in Delaware?
We can. Our crews scale to job size, work with lift and swing stage access, and phase schedules so warehouse and office operations continue uninterrupted.
