Gene Whitmore, who leads our company, set the standard back in 1984: one honest price shown before work starts, no bait coupons, no price changes when we arrive. That standard hasn’t changed.

Our Duct Repair & Sealing Services in Nassau Village-Ratliff
Flex Duct Repair
Flex duct is the standard in Nassau Village-Ratliff’s manufactured and modular homes, and it’s where we see the most failure. The insulation wrapping around these ducts sits in crawlspaces where vapor barriers are often missing or shredded. We regularly pull back saturated, mold-harboring insulation that looked fine from the outside. Our Duct Repair & Sealing team uses infrared cameras to find the thermal signatures of degraded flex runs - the only reliable way to assess condition here. We sleeve damaged sections with new rotomolded duct, secure connections with mechanical fasteners, and seal every joint with mastic. A typical flex duct repair in Nassau Village-Ratliff runs $180-$340 per run.
Mastic Sealant Application
Metal duct joints and plenum connections in older site-built homes around Nassau Village-Ratliff loosen over decades of thermal cycling. Mastic is the only sealant we trust for permanent repair - not tape, which dries and fails in this humidity. We brush or trowel mastic into every seam, collar, and penetration, then verify with a pressure test. This is slow work done right. Mastic sealing for a partial system in Nassau Village-Ratliff typically costs $280-$450; full-system sealing runs $480-$650.
Metal Duct Repair
The older wood-frame homes in the 32011 area, particularly near the Hilliard corridor, sometimes have galvanized metal ductwork from the 1970s and 1980s. Rust-through, disconnected collars, and crushed sections are common. We patch or replace metal runs, transition to new flex where appropriate, and always seal with mastic. Metal duct repair in Nassau Village-Ratliff generally falls between $220-$420 depending on accessibility and extent of corrosion.
Duct Insulation Replacement
This is the service we perform most often in Nassau Village-Ratliff, and it’s the one other companies sometimes skip. When flex duct insulation is saturated with crawlspace moisture, the R-value drops to nearly nothing and mold spores circulate through your vents. We remove the degraded wrap, treat the duct exterior, and install new formaldehyde-free insulation with a proper vapor barrier jacket. Insulation replacement for accessible runs in Nassau Village-Ratliff typically runs $260-$480.

Trusted Brands We Service in Nassau Village-Ratliff
We stock parts and materials from Nikro, Honeywell, and Aprilaire - the same brands serious HVAC contractors specify for their own homes. For Nassau Village-Ratliff customers, this means we don’t order parts from a warehouse in another state and make you wait. Our trucks carry rotomolded flex duct, mastic compound, mechanical fasteners, and replacement insulation in standard diameters. Most repairs are completed in a single visit because we’ve learned what this area’s housing stock requires and we bring it with us. That matters when your crawlspace is 95 degrees in July or you’re running heat on a January morning and a duct joint has finally separated.
Common Duct Repair & Sealing Problems We See in Nassau Village-Ratliff Homes
- Flex duct insulation saturated with crawlspace humidity and mold. In Nassau Village-Ratliff’s low-lying lots, absent or degraded vapor barriers allow ground moisture to wick into crawlspaces, saturating flex duct insulation with mold long before homeowners notice air quality issues - making visual duct inspections nearly useless here. Our infrared camera reveals the thermal signature of wet insulation that looks normal to the eye.
- Expansion and contraction from sharp temperature swings loosen duct joints. Sitting inland from the coast, Nassau Village-Ratliff experiences oppressively humid summers and genuine winter freezes. This cycling causes flex duct connections to work loose over time, pulling unfiltered crawlspace air directly into your supply system. We find separated joints in homes from Ratliff Road to the county line every winter.
- Deteriorated or missing vapor barriers in 1980s-2000s pier-and-beam homes. The original 6-mil plastic vapor barriers in these houses have often shredded or were never installed. Without this ground cover, moisture becomes a chronic, hidden problem that attacks ductwork continuously. We install new vapor barriers as part of comprehensive repairs when the source of moisture must be stopped.
- Crushed or kinked flex duct under manufactured homes. The utility room ducts in modular and manufactured housing in Nassau Village-Ratliff sometimes get compressed during maintenance access or by shifting ground. A crushed duct restricts airflow, strains your HVAC system, and can be repaired or replaced without moving the home.
Pricing for Duct Repair & Sealing in Nassau Village-Ratliff, FL
We’re upfront about numbers because that’s how we work. Here’s what duct repair and sealing costs in the Nassau Village-Ratliff market:
- Single flex duct run repair: $180-$340
- Metal duct patch or section replacement: $220-$420
- Mastic sealant application (partial system): $280-$450

What moves the price? Accessibility is the big one. A duct run in a 4-foot crawlspace with good clearance costs less to repair than one in an 18-inch pier foundation where we’re working on our backs. The extent of mold damage matters too - if insulation is saturated through, replacement takes longer than patching a single joint. We inspect with our camera, show you what we find, and give you the exact price before we start. No surprises on the bill. We also honor our standing offers: $50 off any repair over $250, free second opinion on any written estimate, and a permanent 5% senior and veteran discount.

FAQs - Duct Repair & Sealing in Nassau Village-Ratliff
Yes - saturated duct insulation is almost certainly circulating mold spores through your vents, and in Nassau Village-Ratliff’s humid crawlspaces this is one of the most common hidden sources of respiratory irritation we find. The damp insulation loses its thermal protection too, so your HVAC works harder while blowing contaminated air. We inspect with an infrared camera to confirm saturation, replace the insulation, and can install a new 6-mil vapor barrier to stop the moisture source. Call (866) 995-4721 for a free inspection - estimates are free.
We can often repair sections of 1990s flex duct rather than replacing the entire system, depending on the extent of mold penetration and whether the inner liner is intact. We did a duct repair on a 1990s manufactured home on Pine Cone Lane where the original flex duct connections had separated due to freeze-thaw cycling. Crawlspace vapor barrier was missing, so every joint was coated in black mold. We sleeved the accessible sections in new rotomolded duct, sealed all connections with mastic, and installed a new 6-mil vapor barrier to stop the ground moisture wicking. Full replacement is only necessary when the inner core is degraded or mold has penetrated the liner. We’ll show you the camera footage and give you an honest assessment. Call (866) 995-4721 - estimates are free.
Nassau Village-Ratliff’s inland location brings sharper temperature swings than coastal areas, with summer highs in the 90s and winter lows below freezing - this expansion and contraction loosens flex duct connections and metal collar joints over time. We find the most separation damage in January and February, when months of cycling have worked connections loose. Mastic sealant and mechanical fasteners are the permanent fix; tape fails within a season here. If your system is more than 15 years old, we recommend an inspection before the next heating season. Call (866) 995-4721 to schedule.
Yes - we cover all of the 32011 ZIP code including the Hilliard area and rural Nassau County properties west of Nassau Village-Ratliff proper. Response time to the Hilliard corridor is typically 50-65 minutes from our Jacksonville base. The same upfront pricing, same camera inspection, same 90-Day Done Right Promise apply. Call (866) 995-4721 to book.
In nearly all cases, yes - crushed flex duct under a manufactured home can be repaired or replaced by accessing the crawlspace, without any need to move the structure. We cut out the damaged section, install new rotomolded duct with proper support straps to prevent future crushing, and seal with mastic. The repair typically takes 2-3 hours and costs $200-$380 in the Nassau Village-Ratliff market. We also check for what caused the crush - often inadequate support or prior maintenance access - and fix that too so it doesn’t happen again. Call (866) 995-4721 for an exact quote - estimates are free.
