Mold remediation in Dunedin runs between $1,800 and $5,400 for a typical contained removal in a single room or crawl space, with whole-home treatment pushing toward $9,000 and up depending on how far moisture traveled. You get a written price before we start, and our crews can usually be on-site in Dunedin within 90 minutes because we dispatch from the metro office and serve Pinellas County every day. Call (850) 828-8896 and a live person answers, around the clock.
Dunedin’s older homes, the wood-frame bungalows near Edgewater Drive, the 1950s concrete block houses off Bayshore Boulevard, the flat-roof Florida ranches along Pinehurst Road, hold moisture differently than newer construction. Salt air works on galvanized pipes. High humidity feeds whatever spores found a damp corner. That’s exactly the kind of house our Mold Remediation team knows well. We find the tide mark of moisture and dry past it, then remove what grew while it was wet.

Restoration work we handle






Black Mold Removal in Dunedin
Black mold removal in Dunedin often means Stachybotrys or similar toxic mold growing behind a bathroom vanity, under a leaky window in a 1920s bungalow, or inside a wall cavity fed by a slowly failing galvanized supply line. In Dunedin’s older homes near the water, those slow, hidden leaks are the most common cause. Black mold removal in a single Dunedin bathroom or closet typically runs $1,500 – $3,800, and on homes with extensive wall-cavity growth, the written price reflects measured square footage and affected materials. Remediation here means full containment, negative air pressure, HEPA filtration, removal of saturated drywall or plaster, antimicrobial treatment, and drying to verified moisture levels below normal for the building material. Call (850) 828-8896 to schedule an inspection and get the written number before anyone picks up a tool.
Containment and Air Scrubbing
We seal the work area with plastic sheeting and run negative air machines with HEPA filtration so spores don’t travel through your Dunedin home while we work. The air you breathe during remediation matters as much as the mold we remove.
Removal and Prevention
We cut out saturated drywall and plaster, remove hidden mold colonies, and treat affected framing or block with an antimicrobial. Then we dry the structure to a moisture content below what mold needs to grow, so it doesn’t come back next rainy season.
Mold Removal Contractor in Dunedin
A mold removal contractor in Dunedin does not just scrub the surface, we find where the water came from and fix the conditions that let mold grow in the first place. In Dunedin’s concrete block homes with original terrazzo floors under carpet, a slab leak can keep feeding mold even after visible growth is cleaned. Mold remediation through a full contractor in Dunedin typically runs $2,200 – $6,800 for an average single-room job with moisture mapping, containment, removal, drying, and restoration of the finished wall or ceiling. We walk the house first, explain what we see, what we’ll pull back, and what we’ll protect, then hand you the written price. Call (850) 828-8896 for a free estimate from a local crew that knows Dunedin’s old construction.
Moisture Mapping Before Removal
In the Victoria Drive area, our crew responded to a mold outbreak in a 1950s concrete block home where a failed galvanized pipe behind the kitchen wall had been weeping for weeks. We set containment, used moisture mapping to find readings above 40% throughout the block, and removed water-damaged plaster before structural drying with Dri-Eaz dehumidifiers and Phoenix air movers. The hidden mold colony was eliminated with antimicrobial treatment, and we restored the wall to pre-loss condition.
Restoring What We Remove
Removing mold means cutting out material. Restoring it means new drywall, texture, paint, and trim matched to your Dunedin home, whether that’s a 1926 bungalow or a 1972 concrete block ranch. We leave the wall ready for your family to live with, not a construction zone you’ll stare at for weeks.
Trusted Brands We Service in Dunedin
Our Dunedin mold remediation teams work with professional-grade equipment from Dri-Eaz and Phoenix, the same machines trusted by leading restoration specialists and required by our IICRC and RIA standards. We service all the equipment brands common in Dunedin homes, from 1950s-era plumbing systems to modern HVAC condensate lines, and we keep the parts and materials on hand for fast turnaround on local jobs. Whether the moisture came from a corroded galvanized pipe behind a wall near Main Street or a condensate drain in a flat roof off Beltrees Street, we arrive ready to map it, contain it, and dry it correctly, not just wipe the surface and hope.

AfterCommon Mold Remediation Problems We See in Dunedin Homes
- Galvanized pipes weeping behind plaster over concrete block. Dunedin’s original cast-iron and galvanized plumbing corrodes in salt air, causing slow, hidden leaks that saturate block walls long before standing water or visible staining appears. By the time a homeowner sees a discolored patch, the mold colony behind the wall is often extensive.
- Salt air corroding HVAC drains and condensate lines. Flat-roofed Dunedin homes collect water that feeds mold on wooden trusses and attic sheathing. Category 2 water from condensate overflow pools in attics and soaks insulation before anyone sees a ceiling stain.
- Terrazzo floors under carpet trapping slab moisture. Dunedin’s mid-century homes often have original terrazzo, a moisture-holding material hidden under later carpet installation. Without moisture mapping below the surface, a remediation crew dries only the carpet and pad, leaving the slab wet and mold ready to bloom again.
- Plaster over concrete block holding moisture longer than drywall. In a typical inland city, drywall gets wet, swells, and shows the problem quickly. In Dunedin’s older block homes, water-damaged plaster hangs onto moisture for weeks, creating a hidden mold reservoir that standard surface cleaning won’t touch.
Pricing for Mold Remediation in Dunedin, FL
Typical Dunedin mold remediation jobs run $1,800 – $5,400 for a contained single-room removal with drying, and a full-home crawl space or multi-room project ranges $5,000 – $12,000 depending on square footage, how far moisture traveled, and whether walls or ceilings need full restoration. Black mold in a small bathroom usually costs $1,500 – $3,800. A slab leak under terrazzo with mold in the walls can run $3,500 – $8,500 because we remove flooring and wall finishes, dry the block, and put it all back.

FAQs About Mold Remediation in Dunedin
Salt air accelerates corrosion on original galvanized plumbing and HVAC condensate lines, creating slow, hidden leaks that feed mold behind plaster and inside wall cavities for months before visible staining appears. Dunedin’s older wood-frame bungalows and concrete block homes near the water are especially vulnerable, and a surface cleaning won’t fix what’s growing behind the wall. Call (850) 828-8896 and we’ll inspect the whole house, not just the stain.
Concrete block homes hold moisture in the block and in the plaster that covers it, so mold can grow behind the wall with no visible sign for weeks, while wood-frame bungalows with drywall show water damage faster but conceal mold in framing cavities and under original flooring. Both need moisture mapping and proper drying before removal, which is why our Dunedin crews use Dri-Eaz and Phoenix equipment to find the tide mark and dry past it, not just wipe what you can see.
If the patch covers less than about 10 square feet and you know the water source is fixed, a targeted cleaning may be enough, but in Dunedin’s older homes, what you see on the surface is often a small opening into a larger hidden colony behind plaster or under flooring. We’ll inspect at no charge, tell you honestly whether it’s contained or needs full remediation, and put the written price in front of you before any work starts.
We lift the carpet and pad, inspect and moisture-map the terrazzo, and dry the slab from below if water has been trapped there, because cleaning just the carpet lets mold bloom again within months. In Dunedin’s mid-century concrete block homes, this is one of the most common hidden mold sources we find. Our crews photograph the process and show you the clean-up before leaving.
Category 2 water, also called gray water, from HVAC condensate overflow, washing machine discharge, or slow plumbing leaks, is the most common culprit in Dunedin’s flat-roof homes, and it feeds mold on wooden trusses and attic insulation long before a ceiling stain appears. Salt air speeds corrosion on those condensate lines, so a six-year-old drain fails like a twenty-year-old one would inland. Call (850) 828-8896 for an inspection, estimates are free and written before work begins.
